How to delete my tables who all have the prefix myprefix_?

Note: need to execute it in phpMyAdmin

Answer 1

I found that the prepared statements were a little tricky to get working for me but setting the GROUP_CONCAT_MAX_LEN was essential when you have a lot of tables. This resulted in a simple three-step process with cut-and paste from the mysql command line that worked great for me:

SET GROUP_CONCAT_MAX_LEN=10000;
SELECT CONCAT( 'DROP TABLE ', GROUP_CONCAT(table_name) , ';' ) 
    AS statement FROM information_schema.tables 
    WHERE table_name LIKE 'myprefix_%';

Then carefully cut-and-paste the resulting long DROP statement.
