RE: Strange behaviour of mysqld after adding/dropping a column
Hello Sinisa, have you already found the origin of the problem ? How does the bugs get fixed - are they solved in patch releases or are they solved in a next release of the MySQL server ? Kind regards, Ismaël -Original Message- From: Sinisa Milivojevic [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 02, 2002 1:43 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: Strange behaviour of mysqld after adding/dropping a column Cams Ismael writes: Hello Sinisa, this has nothing to do with services. I have also tried this without creating a service and the result is the same. Normally the services are also stopped automatically when logging of, so I don't understand why I should stop it manually. Also I have tested this constantly by stopping and restarting the service without rebooting the PC (as I described in my bug report), with the same result. So this has nothing to do with services or with rebooting your PC (this was only how I found the bug). In my opinion this is a heavily bug, keeping in mind that restarting mysql after dropping/adding a column messes up your database ! Can you please check this ?

How to use teh FULLTEXT search?
Hello I have created a table: CREATE TABLE data (no int auto_increment, topic text, author text, date date, description text, file text, note longtext, name varchar(15), password (15), folder text, key(no), FULLTEXT(topic,author,description,file,note)); Then, I would like to a FULLTEXT SEARCH in ONE (or 2 or 3) field: ex: SELECT * FROM data WHERE MATCH(note) AGAINTS(text to find); error 1191: can't find FULLTEXT index matching the column list same problem for MATCH(note,author), by example That works only when I do MATCH(topic,author,description,file,note), so with all the fields in fulltext. But that's not what I would like to do. When I see the error message, I tried to create an other index: ALTER TABLE data ADD key(note); error 1170: BLOB column 'note' used in key specification without a key length I have the same problem with IN BOOLEAN MODE. I'm using MySQL 3.23.51 What should I do to use the FULLTEXT search in the desired number of fields?

Known bug or just me? Take II
Hi all again, I've been experimenting and would like to know if there is a known bug in the std function when used with a group by clause? I'd like to know if others have found this problem or is it just me: I have a query without a groupby clause and the avg and std functions work fine. I add a group by clause on a field brought in from another table and the avg still works as expected but the std function returns all 0's. eg: this works: select count(Test1000.OID) as N, avg(Accuracy) as AccAvg, std(Accuracy) as AccStd from Test1000,ROrders WHERE ROrders.OID=Test1000.OID --- N AccAvg AccStd 545 91.3133 13.0047 this does NOT: select count(Test1000.OID) as N,Language, avg(Accuracy) as AccAvg,std(Accuracy) as AccStd from Test1000,ROrders WHERE ROrders.OID=Test1000.OID Group by Language N Language AccAvg AccStd 521 1 91.4302 0. 24 2 87.3846 0.

SQL select rows conditional on same select
Hi, I have 2 tables, X and Y. table X table Y ++---+ ++---+ | id | title | | id | assoc | ++---+ ++---+ | 1 | one | | 1 | 3 | | 2 | two | | 2 | 3 | | 3 | three | | 2 | 4 | | 4 | four | ++---+ | 5 | five | ++---+ I wish to retrieve the X.id and X.title where X.id=Z and also the X.id and X.title where (X.id=Y.assoc) when (Y.id=X.id) but I'm trouble trying to express this as a single SQL statement. Could someone help me out with this, or at least give me a clue as to how to think this one through? In case I haven't explained it very well, I'll describe exactly what I'm doing. Z is a product number, and I want to retrieve the (table X) data for product Z and also the (table X) data for any other products associated with it, represented by table Y. I know I could do it using 2 select statements, firstly just selecting X.id, X.title, Y.id, Y.assoc where X.id=Z (I'm using perl DBI) and then within the perl program create another SQL statement selecting X.id, X.title WHERE Y.assoc IS NOT NULL in the results from the first select. However, I would like to do this with one SELECT if it's possible, for efficiency.

RE: mysql primary key question!
if this interests you at all, i found this yesterday on the evolt.org mailing list. the gentleman who has put this very useful code basically suggested that i could base36 my auto_increment IDs. i will leave this here for those of you who are intersted: http://www.faqts.com/knowledge_base/view.phtml/aid/17710 i use this in the same table. one of the ID fields is auto_incremented. when an ID is generated, i calculate the base36 of that number and put it into my other field which i have to use for my purposes. php or mysql should consider putting this code in their language itself, especially mysql because it can be used for alphanumeric sequences! i dont know if i am making sense, but my problem is solved. hope this helps someone! :) cheers/erick --- Carl McNamee [EMAIL PROTECTED] wrote: Erick, We did that very thing here. Our staff wrote a Unique Record Identifier (URI) program that was called by the programs that actually put the data into the database. The generated URI was then used as the primary key. However, I must say up front that this type of thing is fraught with problems. Here are the ones we ran into that I'm aware of. 1. Performance can stink. If you ask the URI generator for each record things are slow. We got around this somewhat by figuring out how many records a program was working with and requresting a block of URI's. So now you have to modify your programs too! 2. The URI generator must keep track of the URI's it hands out. So you need another database table, and its associated overhead, just to keep track of this. 3. If the system crashes and the URI tables were not updated you could start handing out duplicate URI's after the system recovers. How will your application handle this? The database will reject the records assuming that the URI is your primary key but how do you fix the URI database? If anyone responds with a better way it would be great if you'd post it to the mysql list.

Hi Toby,

I think you should include id, to get the row id
where ctnt_id ORDER BY RAND() LIMIT 5;
$query_result_handle_nme = mysql_query ($query_nme)
or die ('qry failed ! DA tbl must xixt in DA db specifyd bov ');

$row_nme = mysql_fetch_row ($query_result_handle_nme);
echo (brbr);
$tID = $row_id[0];
^^
If you include id in the query this should read $row_nme[0]
$tName = $row_nme[0];
^^
If you include id in the query this should read $row_nme[1]
You can retrieve the other fields by using an increasing index (i.e.
$row_nme[2], $row_nme[3]...)
echo ( $tID );
echo ( $tName );
} // echo (brbr);

Read-Only MySQL
I want to create a CD-ROM which contains a copy of MySQL (for Windows) and a set of MySQL databases. Is it possible to set up a read-only MySQL, that is, a MySQL running from a r/o media?

General query log option in my.cnf?
Is there a way of turning on the general query log in the my.cnf file or do I have to edit the init-script? Personally, I would very much like to have only one place to set all the configuration options (preferrably my.cnf). Setting datadir and other options both in the my.cnf file and the init-script seems to me like a great way of obfuscating the system setup. -- - håkon - 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: minor enhancement request -- adding files to innodb
Chuck, - Original Message - From: Chuck Simmons [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Tuesday, July 09, 2002 5:24 AM Subject: minor enhancement request -- adding files to innodb As a minor enhancement, the innodb database could look at improving its handling of data files. Specifically: 1) Provide mechanisms to allow data and log files to be filled with zeroes while normal operations occur, thus minimizing downtime when the database is grown. version 3.23.50 supports an auto-extending last data file. It solves this by extending the last data file in 8 MB blocks on demand at runtime. Log files are less critical since they are smaller than data files, and you do not need to add new log files because InnoDB writes to them in a circular fashion. 2) Don't store the list of data and log files in the my.cnf configuration file, but provide separate commands to add and remove files or partitions from these lists, and store the list within the database. In Oracle you can do ALTER TABLESPACE and add a new data file at runtime. It would be a nice feature, but no timetable for it is set yet. 3) Provide more robust error recovery so that when we, say, run out of disk space while initializing the data and log files, we don't have to delete all the files and re-create them. The auto-extend option fortunately reduces the probability here because much less disk space needs to be pre-allocated.

Re: hundreds of undefined references from innobase when linking mysql
William, I assume you are compiling with the -O3 gcc flag? Otherwise gcc does not handle 'extern inline' functions right. The problem is probably that your gcc/libtool/linker is configured in a way that it does not do inlining as instructed by the 'extern inline' directive, or it removes the generated code from the archives.

Binding Timestamp Columns with myODBC
Hi, I´ve emailed the list but my problem doesnt seem to have catch much attention. I guess a re-phrasing might help.. It´s pretty simple (I´m using myODBC 3.51 and VC++ 6.0 ) : how do I declare and bind variables/parameters for a TIMESTAMP column? Here´s what I´ve done so far: I declare my starttime var: SQLTIMESTAMP starttime = (SQLTIMESTAMP)(LPCTSTR)20020705195302; Prepare my statement: retcode = SQLPrepare(hstmt,(unsigned char*)SELECT * FROM datav WHERE date_time = ?, SQL_NTS); And bind the parameter: retcode = SQLBindParameter(hstmt,1,SQL_PARAM_INPUT, SQL_C_TIMESTAMP, SQL_TIMESTAMP, 0,0, (void*)starttime, 14, NULL); The application crashes. I tried setting my starttime var to SQLCHAR and SQLINTEGER, with the proper column binding, but it wont work either. Directly executing the statement works, but I my starttime var will change very frequently. Is there any hope for me TIMESTAMP, or should I alter my table and use a integer column with TIMESTAMP-style values...

AUTO_INCREMENT problem even worse!
Hi,
I've continued trying to solve the problem that I emailed yesterday
regarding AUTO_INCREMENT, and I just seem to be going backwards.
The sample database/software that I sent yesterday had a UNIQUE
constraint and a couple of SELECT statements. I thought that removing
them bizarrely made it all work, but it turns out that it doesn't -- it
just takes longer to fail!
I've now reduced the problem to the following simple database/program:
--
CREATE DATABASE test;
CREATE TABLE foo (
id INT NOT NULL AUTO_INCREMENT,
num INT,
str VARCHAR(10),
PRIMARY KEY (id)
) TYPE=BDB;
--
--
use strict;
use warnings;
use DBI;
my $dbh = DBI-connect(
'dbi:mysql:test', 'root', '',
{AutoCommit = 0, PrintError = 0, RaiseError = 1}
);
for (my $deadlocks = 0, my $total = 0, my $i = 1; $i = 5; $i++) {
$total++;
eval {
$dbh-do(INSERT INTO foo (num, str) VALUES (1, 'a'));
$dbh-commit();
};
if ($@) {
if ($DBI::err == 1213) {
$deadlocks++;
print $total: $i: $$: Deadlock! ($deadlocks)\n;
eval {
$dbh-rollback();
};
if ($@) {
print Rollback Error! ($@)\n;
last;
}
redo;
}
else {
print $total: $i: $$: Error! ($@)\n;
last;
}
}
else {
$deadlocks = 0;
print $total: $i: $$: Success!\n;
}
}
$dbh-disconnect();

If I run two of these program simultaneously then one of them always
exits before the 50,000 iterations are up with the error:
Duplicate entry '1' for key 1
Can anybody help explain why?
This looks like a bug to me.

Basic Q's: Numerical Sorting
I have a fairly basic question: How do I sort numerically? Normally when I query using ORDER BY (field), it orders by the first digit (i.e. 1, 10, 2, 21, 3, 32) rather than by number (1, 2, 3, 10, 21, 32). Thanks for any help Dave __ Do You Yahoo!?

Re: Basic Q's: Numerical Sorting
It looks like your field is a text field rather than BIGINT or some numerical field. Changing the field type should solve your problem.

RE: Basic Q's: Numerical Sorting
Here is the solution I posted about t months ago. I would also add, this solution can handle both text and numbers in the same field...: my boss figured out a nice solution to this ORDER BY IF(ABS(Item) 0,LPAD(Item,9,'0'),Item) This will pad numbers ( ok it might not do so hot with DECIMAL, but it can be fixed to work I supposed) with 0 So it should sort 1 2 00010 00022 00050 00230 instead of 1 10 2 22 230 50 And it will skip padding text cause I guess the ABS of text is 0, and the numbers and words will appear separated from each other My boss is smart :) -Original Message- From: CVIOG at UGA [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 09, 2002 4:22 PM To: [EMAIL PROTECTED] Subject: Basic Q's: Numerical Sorting I have a fairly basic question: How do I sort numerically?

No, nothing other than the startup and shutdown messages.
And every once and a while:

But this doesn't happen all the time after restarting the database and I

MResult not in MQuery (here was :...mysql_store_result(MQuery))
mysql_data_seek(MResult, 1); //it's ok here...i suppose you whish to
retrieve data from 2-nd row
row = mysql_fetch_row( MResult) ;// if you have a valid connection(or

Subject: C API: mysql_data_seek
Hi,
I'm using the MySQL built-in C function, mysql_data_seek, for accessing a
particular row from the Result (MYSQL_RES) returned by mysql_store_result.
int sql_result;
MYSQL_RES *MResult;
MYSQL_ROW row;
MYSQL MQuery;
char SQLQuery[];
sprintf( SQLQuery, SELECT * FROM Profile );
sql_result = mysql_query(SQLQuery);
MResult = mysql_store_result(MQuery);
mysql_data_seek(MResult, 1);
row = mysql_fetch_row(MResult);
However, row returns NULL. I wonder if I've made any mistake in the
process. Can someone please help to check? In addition, is there any
special considerations when using this function?
Thanks in advance.

There is no last function in mysql. I know you can do a descending sort by ID and grab the first row to get the same thing.

I have been trying to write a aggregate last UDF function in mysql, and would consider this to be very simple, however, I can't get it to work. I don't really know how to program in C and my understanding of it is quite vague. I really need some help to do this from someone in the community. I have posted several times in the past and haven't heard anything from anyone. I am getting quite frustrated and are about ready to flag this exercise as a great waste of time. I have successful so far got the UDF to compile, and installed. I had to recompile mysql for HPUx to get it to support UDFs in the first place. It has taken me 50+ hours to export several hundred meg of data from access to mysql. I have even written quite a bit of code/scripts to get it to the point where I can start fixing things. So, please, can anyone help me with this. I don't expect someone to do this all for me, but just a LITTLE help would be nice.

undocumented change in behavior?
There appears to be an undocumented change from 3.23.49 to 3.23.51, possibly for the worse. Consider two sessions executing the following sequence of commands on an innodb table (assume maximum ACID properties): session 1 begin; session 1 update table set field = field + 1 where primary_key = 1; session 2 select * from table where primary_key = 1; In version 3.23.49, session 2 returns a row relatively quickly. In version 3.23.51, session 2 blocks. The 3.23.49 behavior is reasonable -- the 2nd session is not required to block because the database is allowed to choose an ordering of transactions when transactions are concurrent and it is reasonable to choose the order where session 2 completes before session 1. So, it appears that version 3.23.51 has different behavior and I don't see this documented in the list of changes. And it could be argued that the 3.23.49 behavior was better. [fyi... one other undocumented change would be the change to the client libraries so that when an application tries to parse a group out of a configuration file, there won't be a core dump. I think this was a bug fix to libmysql.c, adding a '*' to the statement 'for (end= *option ; *(end= strcend(end,'_')) ; )'.] chuck - 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: Lost connection to MySQL server during query
Hi,
My opinion:
This can be a very good reason to kill the socket(is a file too) which is
open during query.
This error show you that you have too many open files in the system.I tested
something like this(Linux - Red Hat 7.2) some time ago and after 2000 (this
mean sockets) clients connected this error occured.

UDF Last Solution
Hi All,
Well I think I actually managed to fumble my way to a solution to this. I
took the example avg_cost UDF function and modified it somewhat (well,
hacked it to pieces). I've tried this before but I actually tried to
rewrite it, bad mistake. This time I just deleted all the bits I didn't
need :o)
This seems to work pretty well, I've tested it with queries dealing with
100,000+ records and seems stable. Of course I don't give any guarantee
that it will work for you, or that it won't blow up your server if you try
it.
Here is the source. Note that it can only get the last value of integers,
not text, real numbers.
Remember, I don't really know what I'm doing in C, so if there is any bad
coding, don't be nasty :o)
Cheers
Miles

Re: undocumented change in behavior?
Chuck, - Original Message - From: Chuck Simmons [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Wednesday, July 10, 2002 1:08 AM Subject: undocumented change in behavior? There appears to be an undocumented change from 3.23.49 to 3.23.51, possibly for the worse. Consider two sessions executing the following sequence of commands on an innodb table (assume maximum ACID properties): session 1 begin; session 1 update table set field = field + 1 where primary_key = 1; session 2 select * from table where primary_key = 1; In version 3.23.49, session 2 returns a row relatively quickly. In version 3.23.51, session 2 blocks. The 3.23.49 behavior is reasonable -- the 2nd session is not required to block because the database is allowed to choose an ordering of transactions when transactions are concurrent and it is reasonable to choose the order where session 2 completes before session 1. normally InnoDB performs a simple SELECT as a consistent non-locking read. That is why the query in .49 returned immediately. But how do you get it to wait in .51? Have you done SET SESSION TRANSACTION ISOLATION LEVEL SERIALIZABLE? In .49 that did not have any effect, but in .50 it changes all SELECTs to use LOCK IN SHARE MODE. This is documented in section 16 of http://www.innodb.com/ibman.html. Below is an example run: Session 1: ... mysql begin; Query OK, 0 rows affected (0.00 sec) mysql update t40 set c = now() where a = 2; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql . Session 2 (started later): mysql select * from t40 where a = 2; +---++-+ | a | b | c | +---++-+ | 2 | jhgjhghghj | 2002-07-10 01:03:48 | +---++-+ 1 row in set (0.00 sec) mysql set session transaction isolation level serializable; Query OK, 0 rows affected (0.00 sec) mysql select * from t40 where a = 2; ERROR 1205: Lock wait timeout exceeded; Try restarting transaction mysql So, it appears that version 3.23.51 has different behavior and I don't see this documented in the list of changes. And it could be argued that the 3.23.49 behavior was better. [fyi... one other undocumented change would be the change to the client libraries so that when an application tries to parse a group out of a configuration file, there won't be a core dump. I think this was a bug fix to libmysql.c, adding a '*' to the statement 'for (end= *option ; *(end= strcend(end,'_')) ; )'.] chuck Best regards, Heikki Tuuri Innobase Oy --- InnoDB - transactions, row level locking, and foreign key support for MySQL See http://www.innodb.com, download MySQL-Max from http://www.mysql.com sql database - 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?

bug with like, latin1 and umlaut ü/y
Description: I was trying to find every row in a table which contains the umlaut ü (ue). MySQL listed every row which contained the umlaut and rows which contained the letter y, but no umlaut... Client and server characterset is latin1. How-To-Repeat: CREATE TABLE test ( name VARCHAR(2) ); INSERT INTO test VALUES ( a ); INSERT INTO test VALUES ( b ); INSERT INTO test VALUES ( ü ); INSERT INTO test VALUES ( y ); mysql SELECT * FROM test WHERE name LIKE %ü%; +--+ | name | +--+ | ü| | y| +--+ 2 rows in set (0.00 sec) mysql SELECT * FROM test WHERE name LIKE %y%; +--+ | name | +--+ | ü| | y| +--+ 2 rows in set (0.00 sec) mysql SELECT * FROM test WHERE name REGEXP .*ü.*; +--+ | name | +--+ | ü| +--+ 1 row in set (0.00 sec) Fix: One can workaround this bug by using REGEXP instead of LIKE.

Bug in drop database mysql 4.0.1-2
I posted a couple of days ago on what appears to be a bug in drop database of mysql-max-4.0.1-2. Here is a recipe to see if others are seeing the same problem. This is on Red Hat Linux 7.2 and is extremely repeatable nor is it limited to a single linux box (ie. not likely hardware problem). When drop database is called in a loop it will eventually cause a hang and most commands will fail thereafter. (except stuff like show variables, show processlist) show processlist shows drop database sitting around waiting for something that never comes :) The server is pretty much dead in the water at this point since nothing else is processed as far as selects, updates etc. While composing this email I've discovered that adding a flush tables command immediately before the drop database seems to solve the problem. While that is a workaround it would be nice to solve the underlying problem :) I've included test.sql and rundeath.csh to help replicate the problem. contents of rundeath.csh #!/bin/csh while 1 date mysql -uroot test.sql end contents of test.sql drop database if exists death; create database death; use death; create table bogus ( crap int default '' not null ); -- Scott Olson Senior Systems Analyst Pason Systems Corp.

In the last episode (Jul 09), Pichan M. said: Is there a query to update record by specify the position of record or row? update tableA set col_name = somthing ...( at row number 123) SQL tables do not have row numbers. The only way to absolutely identify a record is by a unique ID in the record. SQL queries have row numbers, but the only way to guarantee a particular record appears in the same row every time you do the query is by adding an ORDER BY unique_column clause. Just add an INTEGER AUTO_INCREMENT column to your table and use that when you want a particular record. -- Dan Nelson [EMAIL PROTECTED] - 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?

Token parsing incorrect behavior
Description: I have been writing an SQL tokenizer for the phpMyAdmin project, on which I am a core developer. I used this page (Manual 6.1.2 Database, Table, Index, Column, and Alias Names) for reference as to what a valid token was. As well as this reference on SQL User Variables (Manual 6.1.4 User Variables). Most specificly, it states that an identifier CAN start with a number. Ergo, 0xff could be an identifer or a hexadecimal number. However, 0xgff and 0xffg are not valid hexadecimal numbers, and are only valid as identifiers. Use my SQL fragment below, and note the results of the two SELECT queries. While the 0xgff column produces correct results, The 0xfge column does not. The column title is garbled. How-To-Repeat: CREATE TABLE `strtest` ( `0xfge` int(10) unsigned zerofill NOT NULL auto_increment, `0xgff` varchar(255) NOT NULL default '', PRIMARY KEY (`0xfge`) ) TYPE=MyISAM; INSERT INTO strtest VALUES (01, 'Foo'); SELECT * FROM strtest; SELECT 0xfge,0xgff FROM strtest; Fix: Make tokens that fail as being hexadecimal numbers be recognized as identifiers only.

Therefore, if a table contains any variable-length columns (VARCHAR, TEXT, or BLOB), all CHAR columns longer than three characters are changed to VARCHAR columns. This doesn't affect how you use the columns in any way; in MySQL, VARCHAR is just a different way to store characters.

If you want to change them back to Char(x), then you need to change them all at once using a single Alter Table command. You could also try MySQLFront or MySqlMgr. See section 6.5.3.1 Silent Column Specication Changes. Here is an excerpt from the manual: If any column in a table has a variable length, the entire row is variable-length as a result. Therefore, if a table contains any variable-length columns (VARCHAR, TEXT, or BLOB), all CHAR columns longer than three characters are changed to VARCHAR columns. This doesn't aect how you use the columns in any way; in MySQL, VARCHAR is just a dierent way to store characters. MySQL performs this conversion because it saves space and makes table operations faster.

Re: Significance of /*!32312 IF NOT EXISTS*/;

Mysql++
I downloaded mySql++ for mac OS X. It didn't give me any header files but the examples required them. Where can I get those or do I not need them? === Hari Dass S.
