Re: InnoDB create table error 150
Hi! It is a bug in the FOREIGN KEY syntax parser. It is confused by the column name e_foreigncurrency The bug appears if the string 'foreign' is succeeded by a non-space character in a CREATE TABLE statement. Workaround: change the column name to e_currencyforeign, for example. Fixed in 3.23.50.

AND connected Selects on a n-to-m table.
Hi, I have 2 Tables one with the data (lets call the Table Data) and one with Category information (let's call it Category). I have a third Table (dat2cat) with FK_Data and FK_Category that i use to assign up to n categorys to each Dataset in Data. I now want to get a list of datasets with just on datafield with a Unique index on it (lets call it name) from Data that have a certain combination of Categorys (And connected). Normaly i would use Subquerys but since mySql dont support them i have tried following Query: select data.name from data, dat2cat where data.pk_data = dat2cat.fk_data and (dat2cat.fk_category=44 or dat2cat.fk_category = 18) having count(data.name) 1; ( In this example i used just two categorys (Key 44 and 18) when i use more i would put mor 'or' statements in and adjust the having clause) This works fine when there are Results but when there shouldn't be Results i get bacj the first dataset of the Query without the having clause. (That seems rather strange to me ;-) ) Do anyone know what is my error ord knows someone a better way to solve this task (i would like to avoid the usage of temporary tables) Thanks in Advance Simon mail2web - Check your email from the web at http://mail2web.com/ . - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: AND connected Selects on a n-to-m table.
Oh sorry, in my posted version of the Query i forgot a Group by clause. the Query that i have used is: select data.name from data, dat2cat where data.pk_data = dat2cat.fk_data and (dat2cat.fk_category=44 or dat2cat.fk_category = 18) group by data.name having count(data.name) 1; Simon Klaiber mail2web - Check your email from the web at http://mail2web.com/ . - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Change column names
Hi there. Just recently I have started to investigate a possible future use of mySql at my company. As part of this investigation I have come across one seemingly trivial obstacle, but an obstacle very important for me. What I wonder is if there is no means of renaming a column in a sql select phrase in mySql? In, par example, Oracle this i simply done with SELECT group_id g, time t FROM tbl_Groupsn if the desired outcome is that the group_id column is presented as g.

Strange install problem
Hi, after ./configure, make, make install of Version 4.0.1-alpha I executed the mysql_install_db script to finish the installation of mysql. The script says I should execute the commands $/mysql/bin/mysqladmin -u root password 'mypass' $/mysql/bin/mysqladmin -u root -h admin08-1 password 'mypass' The first command worked but when I try the second I get the message: #error: 'HOST 'XXX.XXX.XXX.XXX' is not allowed to connect to this MySQL server' Are there already set rights or what might be the problem?

Thanks for all the answers, you all seemed very surprised by the seemingly easy answer SELECT old_name as new_name FROM ... which made me feel rather at ease.

Replication question
Hi Currently, I maintain two mysql server, hosted by separate ISPs, and keep them synchronised using standard MySQL replication. Server A is master+slave to server B, and likewise server B is master +slave to server A. This allows both servers to receive inserts/updates/deletes and replicate them accordingly. This has, and continues to work well. The problem I have is simple, it has been decided to have a third web site, with an associated database. The replication model I have implemented only works with TWO servers. The only solution to this is to add to one servers my.cnf the option LOG-SLAVE-UPDATES and enable read-only replication to this new server. If I do add this option, and one server logs all its 'native' transactions + 'replicated' transactions, will this confuse the second server ? Will the second server try and apply the remote native transaactions only, or will I get into a loop of a machine applying its own transactions back on to itself ?

MySQL skips a match
Hi!
On a site I'm developing I need to conduct boolean searches. I use a
piece of code I found on:
http://www.evolt.org/article/comment/18/15665/http://www.evolt.org/art
icle/comment/18/15665/
and I've got to say it works really well.
The problem is I cannot search for one specific word because, even
though the word exists on several records, MySQL never returns any
rows.
The word I can't look for is portaria. Any other word works just
fine. I have tried every word I could think of and it works... except
for that one: portaria.
Here is the syntax for the query:
SELECT *, match (titulo,estado,sumario,categoria,tipo,pachave)
against (' portaria ') as relevance FROM dgf_net.dgf_lex WHERE=
match
(titulo,estado,sumario,categoria,tipo,pachave) against=
('portaria')0
HAVING relevance0 ORDER BY relevance DESC
And here is a view of the table:
Field Type Attributes Null Default Extra
id int(11) Noauto_increment
estado varchar(255) Yes NULL
titulo varchar(255) Yes NULL
sumario text Yes NULL
url text Yes NULL
autor varchar(255) Yes NULL
insdata datetime Yes NULL
dipdata date Yes NULL
categoria varchar(255) Yes NULL
tipo varchar(255) Yes NULL
pachave varchar(255) Yes NULL
Indexes : Keyname Type Cardinality Field
PRIMARY PRIMARY 81 id
id UNIQUE 81 id
titulo FULLTEXT None titulo
estado
sumario 1
categoria
tipo
pachave
I'm puzzled! Why is MySQL picky about this specific word?
MySQL is 3.23.36 and PHP 4.0.4pl1
Any help is appreciated! :-)

Re: re-ordering rows
Brent, What Rick said is absolutely correct and you probably are obsessing about something that doesn't matter. But I would venture you are using an auto-number field as the primary key when you could easily change it to a function something similar to: set ID = MAX(ID) + 1. Keith, I agree with what everyone is saying. But for display purposes, it would be nice if MySQL could display a row# for the result set. This could be used to display a line# at the start of each row, like Select count, col1, col2 from table1 where ... and the running count would show Count Col1 Col2 1 ABC DEF 2GHI KLM It would act as sort of a line item# for display purposes only. As everyone mentioned, it doesn't make any sense to store this number in the table. But it might come in handy for display purposes. Few people use native-MySQL to present production/user results. Most interface to MySQL from some other tool/programming language. Storing the data and retrieving it according to use is the job of MySQL. Isn't using the output in some way and/or making it look 'pretty' is a job for that tool?

Re: Suspected Bug
Once tables are CREATEd, the name is listed in SHOW tables using lower case characters, regardless of the case used in the CREATE command. Using upper case table names in RENAME results in the error. Workaround: Using lower case equivalent table names works, regardless of the case used in the CREATE command. Windows does not differentiate between X1 and x1 as table/filenames. *nix does. Perhaps CREATE has been Window-ised but RENAME has not (yet).

RE: Suspected Bug
Hi, this has to be a bug. It seems on windows RENAME TABLE old TO new only works for uppercase table names _after_ an ALTER TABLE old RENAME AS new _or_ if you first rename the table using lower case letters: mysql create table U1 (id int); Query OK, 0 rows affected (0.04 sec) mysql insert into U1 values (1); Query OK, 1 row affected (0.01 sec) mysql rename table U1 to U2; ERROR 7: Error on rename of '.\test\u1.MYI' to '.\test\u2.MYI' (Errcode: 13) mysql alter table U1 rename as U2; Query OK, 0 rows affected (0.01 sec) mysql rename table U2 to U1; Query OK, 0 rows affected (0.00 sec) mysql rename table U1 to U2; Query OK, 0 rows affected (0.01 sec) I think there is some confusion within the mysql server because windows has case insensitive file names. The table is created with lowercase letters on the OS level: mysql create table W1 (id int); Query OK, 0 rows affected (0.05 sec) mysql insert into W1 values (1); Query OK, 1 row affected (0.00 sec) mysql show tables like W%; Empty set (0.01 sec) mysql show tables like w%; +-+ | Tables_in_test (w%) | +-+ | w1 | +-+ 1 rows in set (0.00 sec) C:\mysql\data\testdir w1* Volume in drive C has no label.

A sum of a few columns in where clause?
Hi, I've got query like this: select count(ID) from TABLE where (TABLE.A + TABLE.B + TABLE.C + TABLE.D) 0 A,B,C,D are decimal values. There are over 1 records where A is greater than 0, about 1000 where B is greater than 0, about 500 where C is greater than 0, and about 300 where D is greater 0. I want to get a value of at least 1 of course. But I get a very small value, near 50. The problem is, I think, with NULL columns. Often B,C and D don't have decimal value, but NULL. I thought, that this should be counted like zero.

mysql from localhost vs. remote
Hi mysql list members,
We use the following statements to setup users and rigts for a mysql
server which is accessible locally and via internet:
INSERT INTO mysql.user VALUES
('%','xyz00',PASSWORD('...'),
'N','N','N','N','N','N','N','N','N','N','N','N','N','N');
INSERT INTO mysql.db VALUES
('%','xyz00_%','xyz00','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
The server runs on 66.70.34.150:3307. We can connect via socket locally
and via Host:Port remote:
remote-system mysql -h 66.70.34.150 -P 3307 -u xyz00 -p
= works
local-system mysql -S /var/run/mysql-ext/mysql.sock -u yxz00 -p
= works
But we can NOT connect locally by host:port:
local-system mysql -h 66.70.34.150 -O 3307 -u xyz00 -p
= ERROR 1045: Access denied for user: 'xyz00@localhost' (Using
password: YES)
On a mysqld which is accessible only locally the both INSERT statements
above would have localhost instead of %. Why does localhost not
qualify for %? Do we have to double the entries, having separate ones
for localhost? It does not make sense, does it?
Thanks
Michael

RE: Suspected Bug
I think there are a couple of bugs here: First, per the documentation, 6.1.3 Case Sensitivity in Names (http://www.mysql.com/doc/N/a/Name_case_sensitivity.html), the Windows mysqld is starting with -O lower_case_table_names=1 by default, so all filenames should be converted to lowercase automatically. The create and insert statements are performing as they should. But the RENAME is not, RENAME will create a table in upper case. I believe the first bug is that the RENAME is not respecting the lower_case_table_names option. Second, the error, 7 - Error on rename '.\db\X1.MY1' to '.\db\X2.MYI' (Errcode: 13) is with the index file. After playing around a bit, the following SQL does work: CREATE TABLE X1 (x smallint); insert into X1 values(5); FLUSH TABLES; RENAME TABLE X1 TO X2; My guess is that RENAME is not closing the index file, but FLUSH takes care of that. And the workaround as stated before is to just use lowercase table names. BTW, the following works fine: CREATE TABLE X1 (x smallint); insert into X1 values(5); RENAME TABLE x1 TO x2; -- note names are lowercase --Fred -Original Message- From: DL Neil [mailto:[EMAIL PROTECTED]] Sent: Friday, February 15, 2002 7:20 AM To: SubbaReddy M; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Suspected Bug Once tables are CREATEd, the name is listed in SHOW tables using lower case characters, regardless of the case used in the CREATE command.

table type comparison (poor SELECT performance with HEAP tables ?)
Hello, Well, for my project at work, I've done some small benchmarking of different table types for relatively small sizes (some tens or hundreds of thousands rows - small enough so that key buffer size and other memory factors should not limit performance) and lots of very simple operations. I have the following observation from it : - INSERTs : HEAP tables are incredibly faster than everything else. Then come MYISAM tables (10 to 50 times slower than HEAP), and then the transactional tables (BDB and InnoDB). However the INSERTs were not contained in a single transaction, so this may improve performance. - SELECTs using indexes : HEAP are the best again, but with quite erratic performance. On some occasions they were extremely fast (100 times faster than other tables), and with other record sets they were only twice faster than other tables (which had, on their side, very stable results) - which means even SELECT COUNT(*) FROM my_table is slower than an INSERT ! I find this quite disturbing, and wonder about the reliability of HEAP tables. I wonder if anyone has had performance problems with HEAP tables (erratic performance given that at some time they can be really light-speed, and at others just *a bit* faster than disk-based tables) ? Another problem for HEAP tables is the slowness of DELETE and even TRUNCATE TABLE (you'd better DROP then re-CREATE them). Also, for disk-based tables, setting the 'noatime' flag was a real benefit for lots of very small queries (some tens of percent faster). Endly, it seems that restarting MySQL has some positive impact on SELECTs (strangely enough, because one could think that it would have to reload the indexes and thus spend some more time), expect on HEAP tables (!) ; INSERTs weren't affected though. Are there explanations for some of these facts ?. For HEAP tables, I was wondering if the client side was the bottleneck, but 'top' showed me that MySQL really took most CPU time. This was done with MySQL 3.23.43 source distribution, on a bi-processor Intel Redhat box. The machine is at the same time a production machine but with small loads, and each test was run several times. I can send the test files (4 small PHP scripts ;-)) to the MySQL developpers if they find it interesting.

Re: MySQL 4.0 released
Hello, I'm encountering a serious program fault at using MySQL Win32 client library LIBMYSQL.DLL. I found LIBMYSQL.DLL not thread-safe. When 10 threads are launched to run the following two blocks of C statements, very quickly a program fault window pops up to LIBMYSQL.DLL. block #1 - EnterCriticalSection(dcs); mysql_real_query(db,stmt,strlen(stmt)); res=mysql_store_result(db); LeaveCriticalSection(dcs); block #1 - (in another C function) EnterCriticalSection(dcs); row=mysql_fetch_row(res); nfld=mysql_num_fields(res); flds=mysql_fetch_fields(res); LeaveCriticalSection(dcs); But, if I merged the two blocks into one as: EnterCriticalSection(dcs); mysql_real_query(db,stmt,strlen(stmt)); res=mysql_store_result(db); row=mysql_fetch_row(res); nfld=mysql_num_fields(res); flds=mysql_fetch_fields(res); LeaveCriticalSection(dcs); then, the threads run fine for hours without any program fault pop up. HOWEVER, the second scenario is irrelevant to my (and most multithreaded) application where there are many nested queries of rows. Is there any thread-safe LIBMYSQL.DLL downloadable on mysql.com?? or is there any other solution to make SQL queries by simultaneous threads safe? Thank You!

MySQL 4.0.0-alpha is now available at: http://www.mysql.com/downloads/mysql-4.0.html You can find information about upgrading from MySQL 3.23 to 4.0 at: http://www.mysql.com/doc/U/p/Upgrading-from-3.23.html The MySQL 4.0 release includes a lot of new exciting features, like MySQL as an embedded library, InnoDB (transactions) as standard table type, UNION, multi table delete and much more. MySQL 4.0 is basically a 'reconstruction release' that will enable us to easier add new features to MySQL in the future. The intention is to quickly add features list at: http://www.mysql.com/doc/T/O/TODO_MySQL_4.0.html and then start to work on the 4.1 branch while 4.0 stabilizes. Changes in release 4.0.0 * Added documentation for `libmysqld', the embedded MySQL server library. Also added example programs (a `mysql' client and `mysqltest' test program) which use `libmysqld'. * Removed all Gemini hooks from MySQL. * Removed `my_thread_init()' and `my_thread_end()' from mysql_com.h, and added `mysql_thread_init()' and `mysql_thread_end()' to mysql.h. * Secure connections (with SSL). * Unsigned `BIGINT' constants now work. `MIN()' and `MAX()' now handles signed and unsigned `BIGINT' numbers correctly. * New character set `latin_de' which provides correct German sorting. * `TRUNCATE TABLE' and `DELETE FROM table_name' are now separate functions. One bonus is that `DELETE FROM table_name' now returns the number of deleted rows. * `DROP DATABASE' now executes a `DROP TABLE' on all tables in the database, which fixes a problem with InnoDB tables. * Added support for `UNION'. * A new `HANDLER' interface to `MyISAM' tables. * Added support for `INSERT' on `MERGE' tables. Patch from Benjamin Pflugmann. * Changed `WEEK(#,0)' to match the calender in the USA. * `COUNT(DISTINCT)' is about 30% faster. * Speed up all internal list handling. * Speed up `IS NULL()' and some other internal primitives. * Creating full text indexes are now much faster. * Tree-like cache to speed up bulk inserts and `myisam_bulk_insert_tree_size' variable. * Searching on packed (`CHAR'/`VARCHAR') keys are now much faster. * Optimized queries of type: `SELECT DISTINCT * from table_name ORDER by key_part1 LIMIT #' * `SHOW CREATE TABLE' now shows all table attributes. * `ORDER BY ... DESC' can now use keys. * `LOAD DATA FROM MASTER' auto-magically sets up a slave. * Renamed `safe_mysqld' to `mysqld_safe'. * Added support for symbolic links to `MyISAM' tables. Symlink handling is now enabled by default for Windows. * `LOAD DATA FROM MASTER' auto-magically sets up a slave. * Added `SQL_CALC_FOUND_ROWS' and `FOUND_ROWS()'. This makes it possible to know how many rows a query would have returned without a `LIMIT' clause. * Changed output format of `SHOW OPEN TABLES'. * Allow `SELECT expression LIMIT ...'. * Added `IDENTITY' as a synonym for `AUTO_INCREMENT' (like Sybase). * Added `ORDER BY' syntax to `UPDATE' and `DELETE'. * `SHOW INDEXES' is now a synonym for `SHOW INDEX'. * Added `ALTER TABLE table_name DISABLE KEYS' and `ALTER TABLE table_name ENABLE KEYS' commands. * Allow one to use `IN' instead of `FROM' in `SHOW' commands. * Allow ANSI SQL syntax `X'hexadecimal-number'' *

Problem in MySql while inserting '\'
Hi everybody, This seems to be a definite defect in MySql. While inserting a String into a MySql attribute defined as VARCHAR or VARCHAR BINARY, etc., if a '\' is present in the String, it is simply disregarded, and the remaining part of the String gets inserted. For inserting a '\', we have to use '\\'. However, the question remains that why should I give a special treatment to a String containing '\' ? Normally I am not bothered by the values I insert, as long as it is a String. I think I should be able to insert any String, irrespective of its value, into an attribute specified as VARCHAR, without any special treatment. What do you say about this, and is there any justification for this kind of behaviour ?

Re: re-ordering rows
Bryan, I apologise, did I mistakenly call you Brent earlier!? Indeed. I have a relatively large (few dozen) number of tables that are accessed via PHP and a web interface. The script pulls information from these tables to generate pull-down menus. It would be nice if these pull-down menus were in some inherent logical order--alphabetical, say--as they were when I initially populated the tables. =presentation sequence should be logical: no question about it. =initial table population sequence has little to do with 'real life' - if things changed and a load more rows were added to the table, you would still want to achieve the first objective. Which brings us to... However deleting and adding rows have caused the order to become jumbled--althought the ID numbers are still associated with the name fields in alphabetical order, they are no longer returned in order automatically with a simple SELECT statement. I had hoped there would be some simple command I could run to shuffle the rows back around to inherently be in logical order, so that I wouldn't have to go through scores of SQL statements in my scripts adding ORDER BY statements. Perhaps this is not possible, though. Perhaps MySQL does not care in what order rows are stored internally, and an ORDER BY clause is the only way to impose an outside order on them. This is NOT a MySQL issue, it is rooted in relational theory. In a RDBMS there is no concept of storing data in any particular sequence. Concepts of sequence come into such things as indexing that data, and retrieving the data. BTW this is a common question from people who have 'started' with serial file systems and even certain 'personal' database systems, and are now moving into the SQL/relational world. Let's think about adding data to an existing tbl (as a 'for instance'): it would be fastest if the RDBMS INSERTed the data at the end of the existing file - in file system terminology: open file for write-append, write the row, close the file. If the data was to be inserted somewhere mid-file in order to preserve a 'sequence', what would be involved? Boy do I remember struggling with all this different file formats, and their pros and cons, back at Uni! I mentioned indexing. If the index (let's say a single column for 'purity of thought') is 'small' when compared to the size of the row as a whole, an entire file of indexes/indices is going to be significantly smaller (read: easier to manipulate) than the data-table itself. Consequently when rows are added to indexed tbls, the 'data' can be 'thrown in' (he says most unscientifically) and the indexed data can be inserted (using some suitably smart algorithm) into the correct place in the sequence (of the index file). So data is kept as a 'hodge-podge' (with absolutely no predictable/reliable sequence), but indexes/indices are properly maintained. However, if you are a thinking-reader, when I described INSERTing a para back, you may have thought, 'yes slow storing, but faster retrieval - it's a tradeoff' - and you'd be right (in the trade-off notion)! Trouble is, when you stored the data, yesterday, ready for its retrieval today, did you know the sequence that would be demanded, in advance? Another aspect of relational theory is that the way you build the table, with the access methods/relationships you have in mind today, should not 'fix' things so that you can't react/cope with unanticipated requests/demands tomorrow! In order words, just because you want to pull data out of a table in x-sequence today, doesn't limit you to only that (as some older file systems used to do), if you want to use another sequence, even on another column, tomorrow! That's the good news! The bad news is, yes, you either accept SELECTed data back in some random order; or you add an ORDER BY clause. At least it is not as bad as herding cats! =dn - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

replication and transaction problem
Hello everyone I've read about replication mechanism in MySQL, but I've still got some reservations regarding transactions. In the manual thay say that in case of a transaction, all update instructions are hold in a cache, and on commit they are written to the binary transaction log. After the update instructions are written in binary update log, the slave starts reading them and executint. But what happends if a client executes a query on the slave machine in this period of time? Wouldn't he see an inconsistent database state (a state in the middle of the transaction)? So, actually, on the slave machine it's like there are no transactions at all. Am I wrong somewhere?

Replication + Tmp tables + Flush master/slave = crash
Hei I think we have found a bug in mysql replication. We have some programs that are working against a master DB and that use temporary tables. The hole system works without problems until we run a flush master/slave. Then the replication in the slave DB stops working because of this. How to produce the crash: - We need a system with replication working master-slave. Run f.ex: MASTER: create temporary table testtmp(id text); MASTER: insert into testtmp values (testing); Until here everything works fine. You can continue working with this tmp table without problems. But if we run: MASTER: flush tables with read lock; MASTER: flush master; SLAVE: flush slave; MASTER: unlock tables; MASTER; insert into testtmp values(testing2); The replication in slave will stop working with a error message saying that table testtmp does not exist. This is a huge problem for us. We have many programs working against the master DB, they run for weeks and the process of stopping/starting all of them is not trivial, so we can not stop all of them to run a flush master/slave when the binary update log file gets to big. Is this a bug?, is it another way of doing what we want to do without crashing replication? Do you need more information?

Aborted connection using myodbc
Hi, we're using myodbc2.50.36 with W2k and W98 to connect to our mysql-server (Linux Kernel 2.2.18 - MySQL Version 3.23.38) in the internet. When we send or receive larger amounts of data (we're using Visual Foxpro 7.0 as frontend) we get the aborted connections-Message in the mysql errorlog very often. In my.cnf the wait_timeout is set to 1800 seconds but the connection is aborted much earlier. Here's a piece of the most recent logfile: 020215 16:22:22 Aborted connection 22987 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:25:27 Aborted connection 22991 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:26:02 Aborted connection 22999 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error writing communication packets) 020215 16:28:58 Aborted connection 23574 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:32:38 Aborted connection 24381 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:34:41 Aborted connection 24877 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:34:53 Aborted connection 24970 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error reading communication packets) 020215 16:43:23 Aborted connection 25296 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got an error writing communication packets) 020215 16:48:47 Aborted connection 22968 to db: 'dummy' user: 'dummyusr' host: `my.server.com' (Got timeout reading communication packets) Does anybody know what to do to stop this aborted connections?

RE: MySQL + Access + MyODBC + LARGE Tables
Spoiler: Venu's Suggestion about Dynamic Cursor is the answer On Thu, 2002-02-14 at 20:34, Venu wrote: MyODBC, as compiled today, uses mysql_store_result to get records. This is fine for reasonably sized tables. However, if the table has millions of records, writing the results to a temporary table has many detrimental effects, e.g.: Access seems to hang from the user's perspectiv, Access crashes because there are too many records for it to handle at once (data requirements to great); MySQL creates HUGE temporary tables or bombs if SQL_BIG_RESULT was not set. Probably we can add extra DSN options, to make use of either mysql_store_result() or mysql_use_result(). In the second case, lot of code change is needed in all result set dependency APIs too. That would be nice but perhaps unneeded (see below about your suggestion). So in the case of a very long table, it is important to use mysql_use_result instead. This makes it so that results are returned right away and eases the load on all programs involved. The astute reader will realize that if one uses mysql_use_result and does not fetch all of the records, the next query will return the remaining records from the previous query first. It follows that Access bombs because in statement #2 it is getting results from statement #1. (This is seen from the myodbc.log line: | error: message: Commands out of sync; You can't run this command now in the myodbc3.dll changed to use the said function.) Can you be more specific on this ? And a MS ODBC DM trace will be better to analyze. Sorry, I should have been clearer about this. Yesterday (Thursday) I downloaded the bk source. Aside from many other hacks, I changed execute.c:do_query to use mysql_use_result() instead of mysql_store_result(). In THIS version, I got the Commands out of sync error. To better show what is happening, I just got the souce again, made the said modification and a couple of more verbose debugging output modifications. In the setup, I had checked off Return Matching Records and Trace Here is the sequence of what is happening: [bill@badams myodbc-3.51]$ grep -E 'SQLFree|SQLPre|sync' myodbc.log SQLFreeHandle | info: SQLFreeHandle: 157150 | SQLFreeConnect | SQLFreeConnect SQLFreeHandle SQLFreeHandle | info: SQLFreeHandle: 154988 SQLFreeHandle | SQLPrepare | | info: SQLPrepare: 15bd68 SELECT Config, nValue FROM MSysConf | SQLPrepare | SQLFreeStmt | | enter: SQLFreeStmt: 15bd68 option: 1000 | SQLFreeStmt SQLFreeHandle | info: SQLFreeHandle: 15bd68 | SQLFreeStmt | | enter: SQLFreeStmt: 15bd68 option: 1 | SQLFreeStmt SQLFreeHandle | SQLPrepare | | info: SQLPrepare: 15bd68 SELECT `pcm_test_header_200202`.`serial_hi`,`pcm_test_header_200202`.`ymd_ts` FROM `pcm_test_header_200202` | SQLPrepare | SQLFreeStmt | | enter: SQLFreeStmt: 15bd68 option: 1000 | SQLFreeStmt SQLPrepare | info: SQLPrepare: 15c780 SELECT [column names removed --bill] FROM `pcm_test_header_200202` WHERE `serial_hi` = ?

Try to use Dynamic Cursor Type (OPTION=32) in MyODBC 3.51. YES! The stock 3.51.01.01 myodbc3.dll with Dynamic Cursor Type, Allow BIG Results, and Return Matching rows is the ticket. AFAIK, this satisfies my needs.

API and IPC@CHIP
Dear Sir/Madam I'm fifth year student from Poland. I'm studying at Academy of Minnig and Metalurgy in Cracow (major Electrical Engineering). At the present I'm writing my master thesis. I consider how processors with embedded interface TCP/IP can be used in distributed system data collecting. I use processor German firm Beck (IPC@CHIP; processor family 80186 ). I have access to this processor by web browser and cgi interface (BIOS's this processor include server www ). I must write application which will collect data from outputs this processor. So, I have to (it's one of parts my thesis) write client program for this processor which will connecting with database server. There is atypical operating system similar to DOS. I must write new API to databse. I would like to choose MySQL. In this connection I have a few questions about MySQL. 1. I have open source MySQL but I can't find body of some functions (on base existing API for Windows or Linux I want to write my own API). For example, I can't find body of my_init() function. Where can I find it? Is it possible to see body of this function? (MySQL server will be working in Windows operating system). 2. Do you think that it's possible to write API (at least tiny) for this processor if I have more or less 150k free space on flashdisc whether I should look for another way to solve this problem. 3. I would like to write also another solutions. I wrote application for QNX (because it's hard real time operating system) which uses sockets to communication between Personal Computer and IPC@CHIP by TCP protocol. But now I'm looking for SQL database sytem for QNX. Is it possible to find MySQL for QNX? Where can I find it? If it's impossible, may you recommended me another sql database (shareware or freeware which I can download)? I will be very grateful for any suggestions and advices. I'm not fluent with database at the moment but I think that with your help I will change it pretty soon. If you are interested my work I will describe it for you in details.

Re: When does the timestamp field gets updated?
Only the first TIMESTAMP field gets updated when an updat to a record is made, so if you want to maintain the time a record was created, and when it was updated, use two timestamp fields, the first field will be the time updated, but to do this you must initialize the second timestamp field with NOW() when the record is created.

RE: Left Join problem - Please Help

mysqld unexpectedly crashes
Hello, I am having trouble with Mysqld unexpectedly crashing. I am running mysqld in a situation where there is a nearly constant load on 6 databases, each with about 20 open connections (mostly inserts and selects, occasionally a delete). Once every 3-4 days, at seemingly random points (i.e. in several crashes, it has yet to crash on the same SQL query), one of the mysqld processes crashes and posts to the mysqld.log, complaining of receiving either a signal 11 or a signal 4. One of the running mysqld processes becomes listed as defunct, and the rest just seem to hang there. Stopping the mysqld (/etc/rc.d/init.d/mysqld stop) does not kill the mysql processes. The reset procedure is to kill all of the running clients, re-stop the server, and then start the server. The only thought I have is that I am running Red Hat Linux 7.2, and thus as a result, /usr/bin/safe_mysqld by default forces mysqld to run with --skip-locking (apparently due to locking issues in some Linux systems). -- maybe the combination of a heavy load on the database and running without locking is causing some serious problems. Has anyone out there exerienced a similar problem, or have a better explanation for what's going on? Many thanks, john Siirola [EMAIL PROTECTED] Attached below are excerpts from mysqld.log (with stack traces), as well as other information generated by mysqlbug: -- -- mysqld got signal 11; [.] key_buffer_size=8388600 record_buffer=131072 sort_buffer=2097144 max_used_connections=110 max_connections=255 threads_connected=94 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 563070 K bytes of memory [Note: the server is running with 1024 MB RAM, so this should not be a problem.] [.] Stack range sanity check OK, backtrace follows: 0x80cf68d 0x400287fc 0x400232c4 0x829ae29 0x8283f61 0x82834ab 0x8278df3 0x8116fc8 0x80f4b8e 0x80f42f6 0x80f43a4 0x80f3fa9 0x80eca3d 0x80d5a9f 0x80d8dd3 0x80d4cb0 0x80d4210 Stack trace seems successful - bottom reached [.] Trying to get some variables.

remote file processing with MySQL C API
I have a written a Windows client that accesses a MySQL server (Linux) via the MySQL C API. Stored in the MySQL database are large files (larger than a Mbyte). The C API makes it very easy for the client to query and alter the database. However, I have some special needs that don't appear to be addressed by the C API. The windows client needs the ability to download files from the database. But, before the files can be downloaded to the client, the server needs to insert (into the file) some custom information and then encrypt the entire file. Here are my questions: 1. Is there any way I can get MySQL (by means of the C API) to execute a custom process on certain entries in the database? 2. Once the custom processing has been accomplished, how can I transfer the customized file from the server to the client? 3. Apache is not part of the equation, but I would love to use PHP to solve the above problems. Is there any way that this could be accomplished? Thanks in advance for any advice that you might have.

Selecting records with the highest value no greater than x
I need some help here. Let's see if I can clearly describe it. I have a database containing news stories. Each story is assigned a rating (1 thru 5) indicating its importance. (A story with a rating of 5 is more important than a story with rating of 1.) Now, lets say that there are ten stories in the DB with a rating of 4 and I want to randomly pick one of those stories. I am doing something like this: SELECT * FROM NEWS WHERE RATING=4 ORDER BY RAND() LIMIT 1 That gives me the results I want, but there is a problem. There is no guarantee that there will be any stories in the DB with a rating of 4. If that happens, I want to randomly select a story with the next rating (three in this case) and if there are no stories with a rating of 3 as well, I want to select a story with a rating of 2, and so on and so forth. I would really like to be able to do this with one SELECT statement as opposed to running the above query over and over again, each time decrementing the value of the rating until a record is returned. Any Suggestions? Thanks.

It is also possible that this binary or one of the libraries it was linked agaist is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail key_buffer_size=402649088 record_buffer=1044480 sort_buffer=1048568 max_used_connections=463 max_connections=600 threads_connected=463 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 1619607 K bytes of memory Hope that's ok, if not, decrease some variables in the equation You seem to be running 32-bit Linux and have 463 concurrent connections.

RE: Left Join problem - Please Help
* Miretsky, Anya Select distinct biblio.* from biblio left join keyword on biblio.p_biblio=keyword.fk_biblio where keyword=SOMESTRING; Try swapping the tables: Select distinct biblio.* from keyword left join biblio on biblio.p_biblio=keyword.fk_biblio where keyword=SOMESTRING; The left join is used when there may exist rows in the left table which may not have a related row in the right table, but you still want to include the fields from the left table. The fields from the right table are all NULL in the result row in this case. In this case you probably don't need the left join: Select distinct biblio.* from keyword, biblio where biblio.p_biblio=keyword.fk_biblio and keyword=SOMESTRING; The above statements does not select anything from the keyword table, but the where clause use the keyword table only, not the biblio table... In your case you read all the biblio rows (11,901), and for each of them you do a lookup on the related keywords matching SOMESTRING... this is rarely what you want, the exception beeing when there are very very many keywords and very few biblio rows. It is faster to use the index for all mathing keywords, and then do the lookup to find the related biblio row. By simply swapping the table names, you select FROM the keyword table, and then join with the matching biblio rows. -- Roger query - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Query OK, 0 rows affected (0.00 sec)
mysql insert into flaf VALUES ('hest');
Query OK, 1 row affected (0.00 sec)
mysql insert into flaf VALUES ('Hest');
ERROR 1062: Duplicate entry 'Hest' for key 1
Here, the unique index sees Hest as hest, and because of that the
second row is not inserted.
Why does MySQL have this strange behavoir, treating unique indexes
case-insensitive?
Same thing happens if I use a primary key for the column 'lala'.
Similar test in postgresql seems more logical to me:
hroi=# create table flaf(gnyf char(4) unique);
NOTICE: CREATE TABLE/UNIQUE will create implicit index
'flaf_gnyf_key' for table 'flaf'
CREATE
hroi=# insert into flaf values ('hest');
INSERT 2722204 1
hroi=# insert into flaf values ('hest');
ERROR: Cannot insert a duplicate key into unique index flaf_gnyf_key
hroi=# insert into flaf values ('Hest');
INSERT 2722206 1
Can anyone explain MySQL's behaviour and how I do a workaround making
unique indexes and primary keys case sensitive?
I've been over the documentation a couple times now unable to find
anything.

Re: When does the timestamp field gets updated?
George/Rick, a quick addition. It is not clear from the question: do you want to have the timestamp updated, or do you want to leave it be? RTFM: 6.2.2.2 The DATETIME, DATE, and TIMESTAMP Types ... The TIMESTAMP column type provides a type that you can use to automatically mark INSERT or UPDATE operations with the current date and time. If you have multiple TIMESTAMP columns, only the first one is updated automatically. Automatic updating of the first TIMESTAMP column occurs under any of the following conditions: The column is not specified explicitly in an INSERT or LOAD DATA INFILE statement. The column is not specified explicitly in an UPDATE statement and some other column changes value. (Note that an UPDATE that sets a column to the value it already has will not cause the TIMESTAMP column to be updated, because if you set a column to its current value, MySQL ignores the update for efficiency.) You explicitly set the TIMESTAMP column to NULL. If you want to retain the original value, then you need to use the opposite of clause 2! Regards, =dn timestamp is automatically updated If one uses the timestamp data type for a column inside a table, when executing an update query on said table on a spesific record, will the timestamp column be updated as well or will it retain its first value? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Unique index/primary key case-insensitive?
Hi Andreas, On Sat, 2002-02-16 at 08:52, Andreas Frøsting wrote: Why does MySQL have this strange behavoir, treating unique indexes case-insensitive? Can anyone explain MySQL's behaviour and how I do a workaround making unique indexes and primary keys case sensitive? I've been over the documentation a couple times now unable to find anything. It's a conceptual issue; what you are looking for is not directly related to indexes. Rather, the case sensitivity of a column (and any key taken from there) is dependent on the type of that column. If the type is char, then any operation on that column will by default be case-insensitive. This is actually noted in the manual too, when you look at the sections on CHAR and CREATE TABLE. If you want the column to be case-sensitive, define the column as BINARY CHAR. In your CREATE/ALTER TABLE statement: lala VARCHAR(20) BINARY NOT NULL. That should solve your problem 100% !

RE: [PHP] MySQL question...not sure if this is the correct forum to ask.
Wouldn't replace change all the entries in your table row, same effect as update?
I believe the question is how to test which entry in a form has a new value and
replace/update only that value in the table.
If I have a form...
__
|Employee Record Update|
| |
|ID No: 1234 |
|Name:_|
|Address: _|
|Status: Married |
| |
|Submit|
--
If I have this table...
_
|idnonameaddressstatus|
|-|
|1234Peter45 street Single|
|_|
Which means I only want to replace the status and the name and address remains the
same.
How do you test w/c entries in the form have new values and change only those entries
in the table?
Peter, this is basically what your asking, right?
I actually need to figure this one out myself so I would appreciate any info.
thanks...
luie
What about REPLACE?
http://www.mysql.com/doc/R/E/REPLACE.html
'REPLACE works exactly like INSERT, except that if an old record in the
table has the same value as a new record on a unique index, the old record
is deleted before the new record is inserted'
Hi,
Can the UPDATE statement have conditional check embedded in it? I
have a page that displays a record (in a FORM format) that the user can
change the information on each column. I want to check each column and
see which has been changed and update the table for entries that were
changed only.
for each column data {
if column is changed
then update;
else
do nothing;
}
Maybe I am making this too complicated than it needs and just go ahead
and update all of the columns regardless with the new values, regardless
they are actually different or not.
Thanks in advance,
-Peter
