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

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:
- Open c:\xampp\mysql\bin\my.ini in editor.
- 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.

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 -
- look up for: # The MySQL server [mysqld]
- add this right below it: lower_case_table_names = 2
- 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

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
回答7:
If you have the file my-default.ini rename it to my.ini

ADD following -
- look up for: # The MySQL server [mysqld]
- add this right below it: lower_case_table_names = 1 In file - /etc/mysql/mysql.conf.d/mysqld.cnf
It's works for me.
