In this tutorial, you have learned how to use the MySQL DROP TABLE statement to remove existing tables from a database.How do I import an SQL Dump file into MySQL database? If you often have to deal with this task, you can develop a stored procedure based on the script and reuse this stored procedure. All you need to do is replacing the pattern and the database schema in and variables. Be very careful with this statement To use DROP DATABASE, you need the DROP privilege. So if you want to drop multiple tables that have a specific pattern in a database, you just use the script above to save time. DROP DATABASE drops all tables in the database and deletes the database.

To execute the DROP TABLE statement, you must have DROP privileges for the table that you want to remove. The RESTRICT and CASCADE options are reserved for the future versions of MySQL. Therefore, if you create a table with the same name as the dropped one, MySQL will apply the existing privileges to the new table, which may pose a security risk. It doesn’t remove specific user privileges associated with the tables. Note that the DROP TABLE statement only drops tables. If you drop a non-existing table with the IF EXISTS option, MySQL generates a NOTE, which can be retrieved using the SHOW WARNINGS statement. The IF EXISTS option conditionally drop a table only if it exists. It ensures that you do not accidentally remove non-temporary tables.
The TEMPORARY option allows you to remove temporary tables only. In MySQL, you can also remove multiple tables using a single DROP TABLE statement, each table is separated by a comma (,).
The DROP TABLE statement removes a table and its data permanently from the database. Code language: SQL (Structured Query Language) ( sql )
