How can I change case of database name in MySQL?

Question

My Database name is SPM and I want to change it to spm (small letters).

I tried using

RENAME DATABASE SPM TO spm;

, but I am getting the following error message:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DATABASE SPM to spm' at line 1

My server version: 5.0.45

Answer 1

There is no database command to do it. You basically have to do it outside the database. Below are some references outlining possible solutions. It has been answered pretty good in this question

This is probably what it should look like in your case

mysqladmin create spm
mysqldump SPM | mysql spm

After you have verified that everything is in order you can drop the original database.

drop database SPM

[Note on "RENAME DATABASE" command: This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23.]

Answer 2

RENAME {DATABASE | SCHEMA} db_name TO new_db_name;

This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. It was intended to enable upgrading pre-5.1 databases to use the encoding implemented in 5.1 for mapping database names to database directory names . However, use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.

To perform the task of upgrading database names with the new encoding, use ALTER DATABASE db_name UPGRADE DATA DIRECTORY NAME instead.
