drop tables using regex - MySQL

mysql

Solution

You can use this MySQL procedure:

DELIMITER $$
CREATE PROCEDURE drop_tables_like(pattern VARCHAR(255), db VARCHAR(255))
BEGIN
    SELECT @str_sql:=CONCAT('drop table ', GROUP_CONCAT(table_name))
    FROM information_schema.tables
    WHERE table_schema=db AND table_name LIKE pattern;

    PREPARE stmt from @str_sql;
    EXECUTE stmt;
    DROP prepare stmt;
END$$

DELIMITER ;

For dropping all tables starting with 'a' in 'test1' database you can run:

CALL drop_tables_like('a%', 'test1');

Problem

I have a bunch of tables in a `MySQL` database, some of them starting with phpbb_* which I wanted to delete all of them. Does someone know a way to do so instead of doing ``` drop table <tablename>; ``` every single time? Like a regex? ``` drop table phpbb* ``` or something like?
