String collating support
Hi, I've read in the MySQL manual that If the sorting rules for your language are too complex to be handled with the simple sort_order[] table, you need to use the string collating functions I also read that the best documentations about how to use this feature are the already implemented character sets. (czech, gib5, gbk, sjis, tis160) So, my native language is in this category. Can somebody help me, how to create character sets using this feature?

problem importing null values in mysql 3.23.49 Win32
There appears to be a bug in the Win32 version of Mysql 2.23.49. When I try to read data in (using the load data infile syntax) that contains null values they are converted to 0s. The fields in question are numeric, nulls allowed, default value is NULL. I tried coding them blank, \N and NULL (with and without quotes) and the result seems to be the same. Identical procedure (using \N) in the unix version 3.23.41 seems to work fine. This is a serious problem, as it is necessary to get the database working properly, with automated updates, on a Windoze system. I am surprised not to see any notes or bug reports on this issue. Any suggestions?

Re: max_connections recovery
ok, i turns out I have lots of sleeping connections. This is because I'm using PHP's mysql_pconnect which opens persistent connections so the next connect (on the same process) will reuse the connection. this does appear to improve performance overall, which is good. but it seems to leave lots of sleeping processes on the SQL server. so my question is this: do sleeping connections ever get reused by MySQL? or do they just timeout eventually and waste resources while they're sleeping? Thanks!

Re: 4.0.2 libmysqlclient.so.10 not found
In the last episode (Jul 25), Darren Young said: I am in the process of testing out the 4.0 series of MySQL and am having some problems when I try to install the php-mysql RPM. The machine is a RedHat 7.2 i386 box with all current patches. I pulled down the source RPM for 4.0.2-2 and rebuilt the RPM's with debug enabled then installed all the necessary RPM's. Everything seems to be working ok on the MySQL side except that php is asking for libmysqlclient.so.10 and the only library installed with MySQL-shared is libmysqlclient.so.11. I tried a manual symlink from libmysqlclient.so.10 to libmysqlclient.so.11 and the php-mysql still complains that the library isn't present. I installed the php-mysql RPM with --nodeps just to test it out and sure enough I get 'Call to undefined function: mysql_pconnect' which is the same message you receive if you don't install the MySQL-shared RPM in the 3.0 series. I tried adding /usr/lib /usr/lib/mysql /etc/ld.so.conf and ran ldconfig which yielded the same results. Any thoughts on how I could get this library in place with 4.0.2? The php you installed is linked to the mysql 3.23 shlibs.

Newbie Index Question
I have just begun playing around with MySQL and I have a question about indexing on dates. Part of our system is a work flow management system and we have a table for all documents that we receive. Each document record has several dates to indicate when various processing functions have been completed. In addition to the date we also wish to know the time. In setting up my first table I set the dates up as DATETIME fields. However, indexing on these forces me to specify a date and time or a range. i.e. where ReceivedDate = '2002-07-26 08:15:05' or where ReceivedDate = '2002-07-26' and ReceivedDate '2002-07-27' Since most of the queries I would run that would take the date into consideration would be to find every document that was received on a given date am I better off making two fields, one for ReceivedDate and one for ReceivedTime or is there a way to create an index only on the Date portion of a DATETIME field?

4.0.2 libmysqlclient.so.10 not found
I am in the process of testing out the 4.0 series of MySQL and am having some problems when I try to install the php-mysql RPM. The machine is a RedHat 7.2 i386 box with all current patches. I pulled down the source RPM for 4.0.2-2 and rebuilt the RPM's with debug enabled then installed all the necessary RPM's. Everything seems to be working ok on the MySQL side except that php is asking for libmysqlclient.so.10 and the only library installed with MySQL-shared is libmysqlclient.so.11. I tried a manual symlink from libmysqlclient.so.10 to libmysqlclient.so.11 and the php-mysql still complains that the library isn't present. I installed the php-mysql RPM with --nodeps just to test it out and sure enough I get 'Call to undefined function: mysql_pconnect' which is the same message you receive if you don't install the MySQL-shared RPM in the 3.0 series. I tried adding /usr/lib /usr/lib/mysql /etc/ld.so.conf and ran ldconfig which yielded the same results. Any thoughts on how I could get this library in place with 4.0.2?

It keeps telling me that someone else is trying to access or alter the data and that I have to Copy to Clipboard or Drop Changes.

Index Corruption
I am just getting started with MySQL and one of the first things I was trying is converting one of my larger tables to MySQL to see what kind of performance I would get from some standard queries that I run against it. I built the table and created some indices that I thought would boost the performance for my standard queries. I setup the ODBC on a Windows NT client (the MySQL database is on Red Hat Linux 7.3 and the MySQL version is 3.23.51 that I downloaded on Wednesday.) I ran the query below about 15 times successfully using a Visual Basic program through the ODBC connection. The only queries taking place are SELECT queries. There are no update queries of any kind being run, yet after running the select query about 15 times I start getting the error message below. Is this a standard problem that has a work around? I have dropped the index and recreated it and I get the same behavior. It works fine for a few queries and then the message appears. Thanks for any help. - mysql select * from Documents where type = 1 and (medplancd = ' ' or empno =' '); ERROR 1034: Incorrect key file for table: 'Documents'.

Re: Newbie Index Question
Hi. On Fri 2002-07-26 at 08:34:51 -0400, [EMAIL PROTECTED] wrote: [...] set the dates up as DATETIME fields. However, indexing on these forces me to specify a date and time or a range. i.e. where ReceivedDate = '2002-07-26 08:15:05' or where ReceivedDate = '2002-07-26' and ReceivedDate '2002-07-27' Since most of the queries I would run that would take the date into consideration would be to find every document that was received on a given date am I better off making two fields, one for ReceivedDate and one for ReceivedTime or is there a way to create an index only on the Date portion of a DATETIME field? Your perception of the concept index seems a bit bend. Even if you could specify such an index, you would still have the same problem, as in queries you can access columns, not indexes. Indexes are only used by the query optimizer to retrieve the rows in question faster. Ideally, this is a transpararent mechanism. In your example, the index on ReceivedDate will also be used to retrieve the result for WHERE ReceivedDate = '2002-07-26' AND ReceivedDate '2002-07-27' To accomplish what you want, you could write the Date with LIKE, e.g. WHERE ReceivedDate LIKE '2002-07-26 %' but this would quite surely prevent the use of any index on this column, as would any try to extract the date part with a function (this would be an expression and expressions cannot use indexes in MySQL). You could, as you suggested, split this into two fields. And if your common usage does not use the time part, this looks like a reasonable solution. I, personally, need the time part more often and simply write my queries this way: WHERE Received BETWEEN '$date 00:00:00' AND '$date 23:59:59' where $date is a variable from my application. Not really pretty, but works fine. In short: There probably is not The One, Right Solution.

However, you should first review the text of the message to make sure it has something to do with MySQL. Just typing the word MySQL once will be sufficient, for example. You have written the following: Does anybody know if connecting with named pipes has changed in 4.02? I used to use . For the host name in 4.01 , after I switched to 4.02 I get the error Failed to open named pipe when I try to connect? Any Ideas? As of MySQL 3.23.50, named pipes are off by default (they caused certain kinds of shutdown problems on some systems). To enable them use an --enable-named-pipes option or put an enable-named-pipe line in the [mysqld] group in an option file. I don't know, but would guess that the same change was made in the 4.0.x series between 4.0.1 and 4.0.2, from what you're describing. mike - 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?
