How-to copy a column
Does anyone know the easiest way to copy a column in mysql? I have a table (table1) which has 4 columns, I want to copy all the contents of col1 into col2. Col3 is the primary unique key, so the copy has to keep the data matched with col3. I guess one possible way is to do a select and output to a file and then read from the file for input into col2.

MySQL and Perl DBI Persistent Connection
Hello, I have a Perl CGI script which uses DBI to access MySQL. I noticed that each query through the Perl CGI script using DBI has a connect, query and then quit. I was wondering if there is a way of keeping the connection persistent to Mysql through the Perl CGI script. In my Apache httpd.conf I inserted PerlModule Apache::DBI before all LoadModule lines, but that does not solve the problem. I also downloaded the Apache::DBI module from CPAN and installed it. Perhaps I need to do something else? I also removed any disconnect statements in my Perl CGI script, but I still see the quit in mysql.query.log.

How to move data between tables in a database?
Hello, I would like to move data between tables in mysql within the same database, I am not sure what the best way to go about it is. I do not need to move all the data in the tables, just the output of some select statements. I am using Perl DBI and MySql 4.0.15-standard on RedHat 8.0. I guess I can run a select statement and copy all the data into a Perl array, then copy the data into another MySql table and then delete from the original table. But this seems like too much work, perhaps there is an easier way?

Representing time sheet data in Mysql
Hello, I am trying to store our timesheet data in the Mysql database. I would appreciate suggestions on the database scheme to use. One of the possible ways to do it is to have a table indexed with the employee ID and then having as many columns as there are days in the year. This approach would mean that the table has 200 rows if we have 200 employees and it has 365 columns for each day of the year. Another approach would be to index based on the number of days, i.e., have 365 rows and have as many columns as employees, i.e., 200 columns. If an employee takes half a day off, then I can store an array in the value for that employee ID and that particular day. I am sure there are other approaches to, and I would appreciate any suggestions. Thank you...
RE: Representing time sheet data in Mysql
So if you needed to know status of a work day for an employee day (say 9/1/2003), how did you go about looking it up in your table? Assuming that a employee can be present (p), on vacation (v), sick day (s)? Your table seems to store only the number of hours worked Thank you, Syed Ali (609) 951-2989 -Original Message- From: Dan Greene [mailto:[EMAIL PROTECTED] Sent: Monday, September 29, 2003 11:12 AM To: Syed Ali; [EMAIL PROTECTED] Subject: RE: Representing time sheet data in Mysql In the last timetracking system I built, I used a 'timeentry' table which was basically timeentry_id (pk) employee_id date num_hours_worked task_id I put a few other indexes in there based on the searching that I had to do, but to each their own... -Original Message- From: Syed Ali [mailto:[EMAIL PROTECTED] Sent: Monday, September 29, 2003 11:04 AM To: [EMAIL PROTECTED] Subject: Representing time sheet data in Mysql Hello, I am trying to store our timesheet data in the Mysql database.

Re: how include library correctly in a visual c++ 6 project
Hi Thomas In VC++, go to project file, right clik there, select setting then choose C/C++ then preprocessor. Here type the path c:/mysql/include at include path options. Also you have to add mysqlclient.lib for linker. To do so you should go to Linker tab and explicitly type the file in lib file text box (don't sperate files by ;). Also put the path for additional lib i.e c:\mysql\lib\debug. I've tried this it works... But I want to use Borland C++.do you or any one else can reply to my previous mail Regards, Ali --- thomas WOLFF [EMAIL PROTECTED] wrote: one question how to include your library in visual c++ 6 project because y have many problem y must redefine all path for include ex #include mysql++ - #include ..\directory\mysql++ thank you for your answer Thomas Wolff - Akosystem Am Tiefen Weg 17b 76547 Sinzheim Email: mailto:[EMAIL PROTECTED] Telefon: +49 (0) 7221 / 98 78 40 Fax: +49 (0) 72 21/98 78 42 Handy France : +33 (0)6 84 20 50 86 - 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?

BCC32 problem.................
Hi I'm using Borland BCC32 ILINK32 command line tools for windows to compile link the C source code which contains calls for mySQL C APIs. I've downloaded the borland libraries. The problem I'm having is unable to refer to mysqlclient.lib file from BCC32. The problem is bit confusing. Even for a normal C code (not involving mySQL APIs) it compiles link perfectly when I use BCC32 without -c option (no supression of linker). But if I use BCC32 with -c option it compiles OK and even ILINK32 links the file ok (apparently) but somehow it is not reading the different .obj files present at \BCC55\bin ( i know this because I put remove the path from options and makes no difference). The result is the corrupted exe which throws run time errors. Why I bother to use the -c option and link the objs by ILINK32Because I've to put the mysqlclient.lib file at the link time to avoid unreferrenced symbol error at link time. Could any one pass me through this stage..My mind is now almost dead on this issue..Please help me out!

C IDE for Windows...........?
Hi... I'm new to MySQL. I can play it by ODBC connectivity using JDBC-ODBC bridge. But I want to write code in C using MySQL native C-APIs. One reason for me to switch to MySQL is its C-APIs. I've been using Borland Turbo C/C++ 3.0 for a long time on DOS/Windows OS. When I try to include MySQL headers, it throws errors...which I guess is the problem of long header file names (not complaint with DOS 8.3 file name convention). I'm in search of an IDE that can support MySQL and that should not be much different from the one I'm used to. Could anybody help me out Cheers..
