MySQL Query Browser
The MySQL Query Browser online documentation clearly mentions that it runs on 32-bit Windows operating systems, including Windows 95, 98 and Me. However, while installing it on WinME, I get the following error: The Operating System is not adequate for running MySQL Query Browser 1.1 Can anyone please explain? Thanks.

Re: Concat. operator ||
Hi Paul, Using the following fixed things. However, I am surprised at why it is not working in 4.0.18 (Win32)? Previously I had 4.0.17 (Win32) and things work perfectly. I guess you are right, it's a bug. [mysqld] sql-mode=REAL_AS_FLOAT,PIPES_AS_CONCAT,ANSI_QUOTES,IGNORE_SPACE,ONLY_FULL_GROUP_BY transaction-isolation=SERIALIZABLE Thanks.

Customized auto-increment serial number
Hi, I've a unique requirement where the transaction number should be automatically generated (increment). I can't use AUTO_INCREMENT column. The TRAN_NO is supposed to be in MF format, where: Field: TRAN_NO CHAR(10) M = Encoded current month (A: January, B: February, C: March . L: December) = Current year (e.g. 2004, 2005, ...) F = Running serial number in hexadecimal format (so the smallest number is 1 and the largest number would be F; the serial number will reset to 1 at the beginning of each month) How can I generate this number using MySQL without running into concurrency problem? Also, this is a web-based app and I am planning to use PHP for coding. My production environment is MySQL 4.0.17 on Linux. Development platform is Windows XP with MySQL 4.0.17. TIA.

Validate date
Quote from MySQL documentation ... MySQL allows you to store some wrong date values into DATE and DATETIME columns (like 2000-02-31 or 2000-02-00). The idea is that it's not the SQL server job to validate date. If MySQL can store a date and retrieve exactly the same date, then MySQL will store the date. If the date is totally wrong (outside the server's ability to store it), then the special date value -00-00 will be stored in the column. IMHO, it is the database job to ensure that date/time is valid as it's stored. Hassan Shaikh

Which one is better: CHAR or VARCHAR?

Automatic conversion from `char` TO `varchar`

DST
Gentlemen, Thank you for your informative coverage regarding the captioned. According to your recommendations I've created a separate location table which contains time zone difference in (+/-) minutes. As per the server, my assumptions is that it's located somewhere in California, U.S. (my hosting provider is using EV1). My question is, how to write bulletproof code so that my server code (in PHP) would always store date/time in GMT? Also, how do I tackle DST, and automatically adjust incoming time for daylight saving changes. Appreciate your input and help. Thanks!
