MySQL Table Names revert to LOWER CASE ?

Posted on 2004-08-23
Last Modified: 2012-06-21

I currently administer our MySQL db version 3.23.56 on a LINUX Cobalt Qube server via an external fron-end piece of software.
My Table Names have capital letters at the beginning, i.e. StockMovements, OrderLines.....

We are now implementing a cross-over to a Windows Server 2003 machine.
I have installed MySQL version 4.0.20a and initially it was stated as 4.0.20a-debug. I managed to find another piece of software to take it out of debug mode as I thought this would help with the table names.
The version is now 4.0.20a-max.

If I rename the imported tables say from orderlines to OrderLines, it stays, but if I refresh or close/re-open my front-end, all the table names have reverted back to lower case ?

I have lots of .asp apps which are currently working of my Linux MySQL db using Capitals in the table names and fields. Obviously I do not wish to start re-coding all my web pages.

Please can anyone shed some light on this issue ?

In windows, there is no Case Sensitive options.

If you do "show variables like '%case%' you should get...
| Variable_name          | Value |
| lower_case_table_names | 1     |

You can rename the tables, but it shouldn't matter.  Since your MySQL server is not case sensitive (on windows) you shouldn't have to recode your web apps.  They will just default to the lowercase versions.  Let me know if you end up getting errors.  My guess is it will work just fine as is.

Oh, the reason is that the table name case doesn't matter is the name of the table is taken from a file search (FRM, MYD, MYI) in the database directory.  So unless you have two tables like "orderlines" and "OrderLines", you won't have any problems.

Thanks for your posts.
IOn my current Linux version I have the variable

 lower_case_table_names = 0 (Not 1)

Should I not find a way to change the variable in the windows version to also show 0 ?
I have tried adding a line to the my.ini file, but this seems to make no difference ?

Well windows itself is not case sensitive.  So telling MySql to try to be case sensitive when the underlying operating system isn't doesn't work.  MySQL is really simple, and table names are taken from file names.

This is also the reason why it won't affect your scripts.  On Linux your select statements had to be case sensitive.  On Windows they don't have to be.  So "select * from orderlines" and "select * from OrderLines" will both work.  Try the MySQL commaind line client connected to your windows db server.  You should see that both work with no errors.

Hello scene.  It's been about a week.  Have you had a chance to test things out?  You should find it all works for you regardless of case on Windows.  The lower_case_table_names is more to make thing on Linux work the way they do on Windows the the other way around.
