How to remove all MySQL tables from the command-line without DROP database permissions?


How do I drop all tables in Windows MySQL, using command prompt? The reason I want to do this is that our user has access to the database drops, but no access to re-creating the database itself, for this reason we must drop the tables manually. Is there a way to drop all the tables at once? Bear in mind that most of the tables are linked with foreign keys so they would have to be dropped in a specific order.


Solution

  • You can generate statement like this: DROP TABLE t1, t2, t3, ... and then use prepared statements to execute it:

    SET FOREIGN_KEY_CHECKS = 0; 
    SET @tables = NULL;
    SELECT GROUP_CONCAT('`', table_schema, '`.`', table_name, '`') INTO @tables
      FROM information_schema.tables 
      WHERE table_schema = 'database_name'; -- specify DB name here.
    
    SET @tables = CONCAT('DROP TABLE ', @tables);
    PREPARE stmt FROM @tables;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
    SET FOREIGN_KEY_CHECKS = 1;
