Questions:

I am using windows 7 and xampp i am trying to export my database and while in the process the table names are converted to lower case. I have searched a lot, i know i have to change the value of lower_case_table_names from 0 to 2 but where i have to change this value, in which file?

Answers:

Do these steps:

  1. open your MySQL configuration file: [drive]\xampp\mysql\bin\my.ini
  2. look up for: # The MySQL server [mysqld]
  3. add this right below it: lower_case_table_names = 2
  4. save the file and restart MySQL service

Answers:

On linux I cannot set lower_case_table_names to 2 (it reverts to 0), but I can set it to 1.

Before changing this setting, do a complete dump of all databases, and drop all databases. You won’t be able to drop them after setting lower_case_table_names to 1, because any uppercase characters in database or table names will prevent them from being referenced.

Then set lower_case_table_names to 1, restart MySQL, and re-load your data, which will convert everything to lowercase, including any subsequent queries made.

Try adding/editing lower_case_table_names = 2 in my.ini or my.cnf

I have same problem while importing database from linux to Windows.
It lowercases Database name aswell as Tables’ name.
Use following steps for same problem:

  1. Open c:\xampp\mysql\bin\my.ini in editor.
  2. look for

# The MySQL server

[mysqld]

3 . Find

lower_case_table_names

and change value to 2


if not avail copy this at the end of this [mysqld] portion.

lower_case_table_names = 2

This will surely work.

Look for a file named my.ini in your hard disk, in my system it’s in

c:\program files\mysql\mysql server 5.1

If it’s not my.ini it should be my.cnf

If you have the file my-default.ini rename it to my.ini

Also works in Wampserver.
Click on the Green Wampserver Icon, choose MySql, then my.ini.
This will allow you to open the my.ini file.
Then –

  1. look up for: # The MySQL server [mysqld]
  2. add this right below it: lower_case_table_names = 2
  3. save the file and restart MySQL service

Important Note – add the lower_case_table_names = 2 statement NOT under the [mysql] statement, but under the [mysqld] statement
