From the easy way to the crazy way here is how to rename a Mysql Database.
1. Using phpMyAdmin
Log into your phpMyadmin select the database that you want to rename and click on the Operations tab

2. You can use mysqldump (This is the one I use or very large databases)
mysqldump -u username -p -v SourceDB > SourceDB.sql mysqladmin -u username -p create NewDB mysql -u username -p NewDB < SourceDB.sql
3. Create a new database and migrate all the tables from the old one to the new one.
4. The Crazy Option
Shutdown the MYSQL Database Locate the location where MYSQL save the databases. (ususally they are located in /var/lib/mysql/ on a Linux platfrom) Rename All Old database Files to new Database filenames (something like mv olddb.* to Nename.*) Restart The Database Make sure you check the Grant permission.

. Note If the check box has a gray background, click Form Field Shading
on the Forms toolbar to remove the gray shading.
Click the next cell where you want to insert a check box, and then press CTRL+Y to insert another check box.
After you insert a check box for each item that you want, click the top right cell and type the text for the first item. Repeat this step for each item in the list."
