Problem with permissions on Windows in 4.0.11a Gamma?
Hello, all: It seems that the 4.0.11a Gamma release on Windows allows all users to connect, even though they don't have connect permissions in the user table. Could this be right? I'm running on WinXP. I apologize - I'm new to MySQL, so please let me know if I am reading the documentation incorrectly. http://www.mysql.com/doc/en/Privileges.html Comment lines are preceded by // in this example // connect to MySQL without providing a username or password C:\mysql\binmysql Welcome to the MySQL monitor.

Re: Help with Query
OK, attempt number two: Let's see what you are after is the number of emails that a member has received (say 25), and then you also want the number of members that have received x-number (say 25) emails. Is this even close to what you want? I think the only way to answer the question(s) is to use more than one query (specially since MySQL doesn't support sub-selects). Here's what I came up with: (it's probably not pretty and more than likely not completely correct, but I haven't been playing with MySQL than long). CREATE TEMPORARY TABLE member_counts SELECT member_id, COUNT(mailing_id) AS mail_count FROM member_mailings GROUP BY member_id; This puts the number of mailings into a temp table. Now we do: SELECT mail_count, COUNT(member_id) FROM member_counts GROUP BY mail_count; I *think* that these to step should give you what you are after. jeff At 22:47 -0800 3/17/03, Daren Cotter wrote: This seems to be doing the same thing as the previously mentioned query...simply listing all mailing IDs, along with the # of members it was sent to.

MySQL/InnoDB-4.0.12 is released
Hi! InnoDB is a MySQL table type which provides transactions, foreign key constraints, and a non-free Hot Backup tool. InnoDB is included in all versions of MySQL-4.0, which you can download from http://www.mysql.com/downloads/mysql-4.0.html. MySQL-4.0.12 is a bugfix release of the MySQL-4.0 branch, which will soon be declared stable. Full changelog: * In crash recovery InnoDB now prints progress information about the rollback of large transactions. * Fixed a bug/feature: if your application program used mysql_use_result(), and used = 2 connections to send SQL queries, it could deadlock on the adaptive hash S-latch in btr0sea.c. Now mysqld releases the S-latch whenever it passes data from a SELECT to the client. * Fixed a bug: MySQL could erroneously return 'Empty set' if InnoDB estimated an index range size to 0 records though the range was not empty; MySQL also failed to do the next-key locking in the case of an empty index range. * An outstanding bug: SQL command SET FOREIGN_KEY_CHECKS=0 is not replicated properly in the MySQL replication.

RE: Problem with permissions on Windows in 4.0.11a Gamma?
Mark, Thanks for your note. I did read this page in the manual, especially this paragraph. The default privileges on Windows give all local users full privileges to all databases without specifying a password. To make MySQL more secure, you should set a password for all users and remove the row in the mysql.user table that has Host='localhost' and User=''. You should also add a password for the root user. The following example starts by removing the anonymous user that has all privileges, then sets a root user password: C:\ C:\mysql\bin\mysql mysql mysql DELETE FROM user WHERE Host='localhost' AND User=''; mysql QUIT C:\ C:\mysql\bin\mysqladmin reload C:\ C:\mysql\bin\mysqladmin -u root password your_password In my example, you will see that I did DELETE FROM user to remove all rows where username is blank. However, I did not reload the service. When I did, it now looks like the correct behavior is happening. -ms -Original Message- From: Mark Matthews [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 18, 2003 5:53 AM To: Michael Shulman Cc: [EMAIL PROTECTED] Subject: Re: Problem with permissions on Windows in 4.0.11a Gamma? -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Michael Shulman wrote: Hello, all: It seems that the 4.0.11a Gamma release on Windows allows all users to connect, even though they don't have connect permissions in the user table.

MySQL Users Conference
Do you plan on attending the first MySQL Users Conference to be held next month in San Jose, Calif? Our company is one of the sponsors for this event and we very much look forward to meeting many of you. If you haven't already registered for this important event, we strongly encourage you to do so. Check out the following link for a special discount on conference passes https://order.mysql.com/?sub=pgpg_no=14ref=blw7 . There will be a wealth of information presented at this event and it will be a great opportunity to network and learn from many of the leading minds in the MySQL community. As I haven't really seen much discussed about this event here, I just wanted to drum up a little interest to make sure folks here were aware of this event. Of course, this is an official MySQL event hosted by MySQL AB and many of the employees of MySQL AB will be on hand. Look forward to meeting many of you next month in San Jose.

Problem with large file support

Fulltext Search Problem
Hi,
Why does this not work?
SELECT * FROM News WHERE category='sport' AND MATCH
(subcategory,headline,summary) AGAINST ('madrid') LIMIT 1,25
If i remove the category='sport' AND from the WHERE clause it works - yet all
documents in the db currently have category='sport'. Is it not possible to mix
a MATCH with another condition?
Any ideas, or is the only solution to run the first query, store the results in
a temp table, and then run a 2nd query.

@strong{DATETIME}

@code{hexadecimal B5 2E 11 5A 02 00 00 00}
@end itemize
At first I thought this example made sense, since 0x025a112eb5 is
decimal 10101010101. But it's supposed to be two 32-bit integers
rather than one 64-bit integer, and the two parts would be 0x0002
and 0x5a112eb5, which don't seem to convert to a date and time.
Anyway, it appears that the date part of a DATETIME is stored less
efficiently than a DATE, and the time part is stored less efficiently
than a TIME (though that's just because 1 byte of the 4 is always
00). Presumably that's for ease (and hopefully speed) of
calculation.
@strong{TIME}
@itemize @bullet
@item
Storage: a value offset from 8385959, always three bytes long.
@item
Example: a TIME column containing '01:01:01' looks like:@*
@code{hexadecimal 75 27 00}
@end itemize
0x2775 is decimal 10101, so the example doesn't seem to involve an
offset.

maximum manageable table sizes for performance
Hi all, I am in the process of planning for the construction of a very large database and I wanted to do a reality check before hand. in this database a typical table would be 100,000,000 rows and some tables could be as large as 100 times that, 10,000,000,000. I am wondering: 1- is it possible? 2- how do the indices files grow with the number of rows. is it more or less linear or should I expect some explosion in size as the number of rows increases. 3- I would need to do joins on as many as 5 tables of that size. providing that joins are done on appropriately indexed columns. how would you expect the performance to be like? for my purposes it doesn't need to be real time. but a response within 15 minutes is probably necessary. 4- some of these tables might need to sit on an nfsed file system. would that be a completely crazy thing to do? 5- what sort of server memory you would think be a minimum to handle this DB. and lastly: 6-would any other DBMS (than mysql), say commercial ones, be better equipped to handle such data sizes? thanks. any relayed experiences the subject of large database is very much appreciated. best Murad - 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?

Selecting only ONCE from multiple tables
I'm just getting used to SQL/MySQL, so there is likely a name for this or it may be well known -- I just haven't either come across it, or haven't made the associations between all the parts yet. I have 2 tables, one a temp table, and they have the same columns. I'd like to be able to select from both tables and get one listing. Table 1 is Cases, Table 2 is Temp. They have columns Name, Amount, Zip. SELECT * FROM Cases AS C, Temp AS T WHERE (C.Amount 500 OR T.Amount 500); produces a list of 38 rows w/ 6 columns (the first 3 columns from Cases, the 2nd 3 columns from Temp). This should select 2 rows from Temp and 4 from Cases. (The 2 rows in Temp are duplicates of the ones in Temp.) Instead of getting one list with 3 columns, this list iterates through each row in Temp once for each row in Cases and also includs the duplicated rows a 2nd time. While I expect the duplicated rows to show up twice, how do I produce a combined list. Another way to put it is that I have 2 tables w/ similar columns and want to select from the 2 of them and take the results and either output it or put it into a new table. Thanks for any suggestions or help.

Re: Selecting only ONCE from multiple tables
UNION is new in MySQL 4. Be careful of that. http://www.mysql.com/doc/en/UNION.html If you don't have MySQL 4, your problem becomes a bit tricky, because MySQL doesn't know that T.Amount and C.Amount are conceptually the same, so it won't group the columns. Basically, you want to select T.* if T.Amount 500 and C.* if C.Amount 500. Which, without UNION, is only possible through separate queries, unless I'm missing something.

MySQL 4.0.12 has been released
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, MySQL 4.0.12, a new version of the popular Open Source Database, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ and mirror sites. Note that not all mirror sites may be up to date at this point of time - if you can't find this version on some mirror, please try again later or choose another download site. Starting with MySQL 4.0.12, MySQL 4.0 is now labelled as production instead of gamma. Users of MySQL 3.23 are encouraged to upgrade, since MySQL 3.23 will now be phased out slowly. It will still be supported, but only critical bug and security fixes will be applied to the 3.23 code base. News from the ChangeLog: Functionality added or changed: * `mysqld' no longer reads options from world-writeable config files. * Integer values between 9223372036854775807 and 999 are now regarded as unsigned longlongs, not as floats. This makes these values work similar to values between 1000 and 18446744073709551615. * `SHOW PROCESSLIST' will now include the client TCP port after the hostname to make it easier to know from which client the request originated. Bugs fixed: * Fixed `mysqld' crash on extremely small values of `sort_buffer' variable. * `INSERT INTO u SELECT ... FROM t' was written too late to the binary log if t was very frequently updated during the execution of this query. This could cause a problem with `mysqlbinlog' or replication. The master must be upgraded, not the slave. (bug #136). * Fixed checking of random part of `WHERE' clause (bug #142). * Fixed a bug with `multi-table updates' with `InnoDB' tables. This bug occured as, in many cases, `InnoDB' tables can not be updated on the fly, but offsets to the records have to be stored in a temporary table. * Added missing file `mysql_secure_installation' to the `server' RPM subpackage (bug #141). * Fixed MySQL (and `myisamchk') crash on artificially corrupted `.MYI' files. * Don't allow `BACKUP TABLE' to overwrite existing files. * Fixed a bug with multi-table `UPDATE's when user had all privileges on the database where tables are located and there were any entries in `tables_priv' table, i.e. `grant_option' was true. * Fixed a bug that allowed a user with table or column grants on some table, `TRUNCATE' any table in the same database. * Fixed deadlock when doing `LOCK TABLE' followed by `DROP TABLE' in the same thread. In this case one could still kill the thread with `KILL'. * `LOAD DATA LOCAL INFILE' was not properly written to the binary log (hence not properly replicated). (bug #82). * `RAND()' entries were not read correctly by `mysqlbinlog' from the binary log which caused problems when restoring a table that was inserted with `RAND()'. `INSERT INTO t1 VALUES(RAND())'. In replication this worked ok. * `SET SQL_LOG_BIN=0' was ignored for `INSERT DELAYED' queries. (bug #104). * `SHOW SLAVE STATUS' reported too old positions (columns `Relay_Master_Log_File' and `Exec_master_log_pos') for the last executed statement from the master, if this statement was the `COMMIT' of a transaction. The master must be upgraded for that, not the slave. (bug #52). * `LOAD DATA INFILE' was not replicated by the slave if `replicate_*_table' was set on the slave. (bug #86). * After `RESET SLAVE', the coordinates displayed by `SHOW SLAVE STATUS' looked un-reset (though they were, but only internally). (bug #70). * Fixed query cache invalidation on `LOAD DATA'. * Fixed memory leak on `ANALYZE' procedure with error. * Fixed a bug in handling `CHAR(0)' columns that could cause wrong results from the query. * Fixed rare bug with wrong initialization of `AUTO_INCREMENT' column, as a secondary column in a multi-column key (*note `AUTO_INCREMENT' on secondary column in a multi-column key: example-AUTO_INCREMENT.), when data was inserted with `INSERT ... SELECT' or `LOAD DATA' into an empty table. * On windows, `STOP SLAVE' didn't stop the slave until the slave got one new command from the master (this bug has been fixed for MySQL 4.0.11 by releasing updated 4.0.11a windows packages, which include this individual fix on top of the 4.0.11 sources). (bug #69). * Fixed a crash when no database was selected and `LOAD DATA' command was issued with full table name specified, including database prefix. * Fixed a crash when shutting down replication on some platforms (e.g. Mac OS X). * Fixed a portability bug with `pthread_attr_getstacksize' on HP-UX 10.20 (Patch was also included in 4.0.11a sources). * Fixed the `bigint' test to not fail on some platforms (e.g. HP-UX and Tru64) due to different return values of the `atof()' function. * Fixed the `rpl_rotate_logs' test to not fail on certain platforms

No, that should work. Do any items in the db have the text 'madrid' in
them?
Does it fail with an error or does it simply not return any results? Are
you
executing it on the command line? If not, are you checking for errors?
What
version of MySQL do you have?

Hi,
Why does this not work?
SELECT * FROM News WHERE category='sport' AND MATCH
(subcategory,headline,summary) AGAINST ('madrid') LIMIT 1,25
If i remove the category='sport' AND from the WHERE clause it works -
yet all
documents in the db currently have category='sport'. Is it not possible
to
mix
a MATCH with another condition?
Any ideas, or is the only solution to run the first query, store the
results in
a temp table, and then run a 2nd query.

Hi, I do understand what you're saying and I did read the 4.0.12 changelog and appreciate the addition of the TCP port in that display, but all the hostnames in the processlist are displaying as the localhost of the mysql server that they are connecting to instead of the hostnames of the server that is connecting.

Search back through the archives of this list and the MyODBC list. The short answer is that Access is f**ked and will crash when left unattended. I had originally thought that it only affected Access 2002, as Venu couldn't reproduce my problem under Access 2000. But apparently not. One dodgy fix which I've considered but not used is to have a hidden form with a timer event which opens an ADO connection to MySQL and closes it every 3 minutes. I haven't tested it but since the problem only happens when there is no activity between Access and MySQL, I assume this will work.

Exactly. There's a bit of an explanation it the manual here: http://www.mysql.com/doc/en/Multiple-column_indexes.html I try to think of it this way: if I have a query that *always* uses more than one column to search for data, it's a great candidate for a multiple column index. The user/pass query you have above is a good example. I tend to use multi-column indexes in reporting queries a lot. In sales reports, for example, I'm almost always querying by date as well as some other criteria like sales rep id. Having a multi-column index on (sales_rep_id, date) would help when searching by sales_rep_id alone, or sales_rep_id and a date range -- but wouldn't help when searching by date alone. In contrast, having an index on (date, sales_rep_id) would help searching by date alone, or date and sales_rep_id -- but not on sales_rep_id alone. The order of the columns in the index really depends on your particular queries. Another thing to keep in mind is that if all the columns in your query exist in the index, then mysql can use *just* the index to return the data -- which means it never even has to open the table. That can be a great optimization for big tables with lots of columns. Furthermore, if I understand correctly, if I did the query like so: SELECT * FROM rep_table WHERE rep_password = '$pass' AND rep_login = '$user'; I would NOT get the benefit of the index either since I changed the order of my search, is that true? No, the mysql query optimizer is smart enough to figure this out. To see it working, you can always use the EXPLAIN keyword: http://www.mysql.com/doc/en/EXPLAIN.html EXPLAIN will show you which index is being used for your SELECT statement (or if no index is being used...). Invaluable when trying to optimize your SELECTs. --jeff -Original Message- From: Bruce Feist [mailto:[EMAIL PROTECTED] Here's a close analogy for you. In a library, fiction books are typically sorted first by author's last name, and then by author's first name. Think KEY (author_last, author_first). This makes it fast to find all books by an author with a given last name, and even faster to find all books given the author's first and last names... but it doesn't help if you need to find books by author's first name.

With two separate indices, it'll use the index with the lowest cardinality, pull all the matching records, and discard the ones where the other field doesn't match your criteria. The field order only matters if you also want to be able to do a query on a_id. Mysql will be able to use a KEY (a_id,b_id), but not a (b_id,a_id) one, since the field it's interested in is not the first one. most of the time, you'll end up generating two indexes: (a_id,b_id), and (b_id). - 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?

link error with MyODBC 3.51 on Mac OS X
Hi, I found a problem with your binary distribution of MyODBC 3.51 for Mac OS X. I downloaded the binary distribution of MyODBC 3.51 for Mac OS X (I am currently using Mac OS X 10.2.4 Darwin 6.4). When I tried to use iODBC I got a dynamic linking problem. More specifically, when running odbctest, I get: dyld errors during link edit for file /Users/mysqldev/venu/local/mysql/lib/mysql/libmysqlclient.10.dylib dyld: odbctest version mismatch for library: /Users/mysqldev/venu/local/mysql/lib/mysql/libmysqlclient.10.dylib (compatibility version of user: 11.0.0 greater than library's version: 4.0.0) So I checked your driver with otool: otool -LD libmyodbc3.so libmyodbc3.so: /Users/mysqldev/venu/local/lib/libiodbcinst.2.dylib (compatibility version 4.0.0, current version 4.6.0) /Users/mysqldev/venu/local/mysql/lib/mysql/libmysqlclient.10.dylib (compatibility version 11.0.0, current version 11.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 63.0.0) So at this point I am stuck (unless I rebuild the driver).

Or even KEY (`rep_password`, `rep_login`) This would actually be just as good if you were doing a lookup on both fields. Given that the query would most likely be something like: SELECT * FROM rep_table WHERE rep_login = '$user' AND rep_password = '$pass'; And I would never really search for just the password, so the KEY `rep_password` (`rep_password`) Is sorta a useless index? Yes. Furthermore, if I understand correctly, if I did the query like so: SELECT * FROM rep_table WHERE rep_password = '$pass' AND rep_login = '$user'; I would NOT get the benefit of the index either since I changed the order of my search, is that true? Almost certainly *not*. Most RDBMSs have optimizers good enough to realize that the order of the conditions is irrelevant. I assume that this is true of MySql.

Strange problem on the difference of mysql connection between cgi and shell
Hi, I am coding a cgi program to query the records from the mysql tables. When I execute the sql query (which is a join operation on two tables) in the mysql shell, the results are shown correctly. However, if I use cgi script to execute the same query, the web browser just crashed after a while (5 or 6 minutes which is the same as the query execution time ). I am guessing the problem is relevant to the larger result (more than 10,000 records), because if I execute the query against another two tables which have the same structure but contain the less records, both cgi script and shell method can work. So anybody can help me figure out the problem? I have adjusted the configuration of mysqld to be a huge one but still failed.

mysql using wrong indexing keys
I am running this query that is awfully slow. It's a simple query between two heap tables with two joins. I ran a explain statement to see why it is running so slow and realized that mysql was using indexing for one of the lesser inefficient joins! I fixed this problem by adding a STRAIGHT_JOIN to the SQL statement. However, this seems kinda inelegant. Is there a way to specifically specify which index to use in the join? I looked it up on google and there seems to be a USE KEY command which forces mysql to use a particular index. However, it does not seemed to be supported in MySQL 3.2.3 .

Trouble upgrading to 4.0 on Mandrake Linux
I am running Mandrake Linux 8.2, with the RPMs upgraded to 9.0. It had MySQL 3.23 running on it. I downloaded the current version of 4.0 from mysql.com tonight and isntalled it. I changed the old files from /usr/share/mysql to /usr/share/mysql3.23 and /var/lib/mysql to /var/lib/mysql3.23 (where the databases are stored). I created a new /usr/share/mysql and unpacked the MySQL 4.0.x tarball into the directory, then followed the install instructions (basically changing /usr/local/ to /usr/share/ in bin/mysqlaccess and running scripts/mysql_install_db). I copied the 4.0 executables to /usr/bin (which I did without thinking -- realizing I forgot to backup the original 3.23 binaries in that directory -- my big mistake). Now when I type mysqld_safe --user=mysql the daemon starts, but I get another message almost immediately that it is exiting. What's wrong and what do I need to do to get 4.0 working? Why is the daemon quitting on me? Is anyone else using Mandrake and encountering similar problems? Thanks!

a conundrum -- php/mysql script
Dear all, Have written a wrapper to Christian Novak's excellent biffwriter class which writes out excel files based on query to a mysql database. A for loop, $zz=1; $zz =61; $zz++: generates the id needed for the WHERE condition: $sql = SELECT $arv, DATE_FORMAT(date_rec,'%m-%d-%Y') as nice_date from arviContacts WHERE fid=$zz; which is then passed to a function writeARV($sql); which then loops through the database for all data pertaining to that id, ($numoffields=mysql_num_fields($result);) opens a file, writes out the column heads and then loops through the data and parses into an excel file. 1. The counter is being incremented correctly, 2. all the files are created correctly, 3. all the column heads are generated correctly 4. and the data for 4 specific files do NOT get written in. 5. The file id numbers are 47,49,51 and 57 (all odd numbers but only 3 are in sequence) 6. These files are generated with NO DATA while all the other files are generated with the data. 7. If I explicity change the counter to one of these numbers and run the script singly, then these specific files get generated correctly WITH all the data. I do not even know how to begin to debug this which is why I posted to both lists -- any pointers? clues?
