-- Assuming the user wants to delete all tables in a MySQL database
-- Connect to your database first

-- Get a list of all tables in the database
SELECT GROUP_CONCAT(table_name) INTO @tablesToDelete
FROM information_schema.tables
WHERE table_schema = 'your_database_name';

-- Construct the SQL query to delete all tables
SET @query = CONCAT('DROP TABLE IF EXISTS ', @tablesToDelete);

-- Execute the SQL query to delete all tables
PREPARE stmt FROM @query;
EXECUTE stmt;
