MySQL DROP TABLE
statement syntax
To remove existing tables, you use the MySQL DROP TABLE
statement.
Here is the basic syntax of the DROP TABLE
statement:
DROP [TEMPORARY] TABLE [IF EXISTS]
table_name [, table_name] ...
[RESTRICT | CASCADE]
- The
DROP TABLE
statement removes a table and its data permanently from the database. In MySQL, you can also remove multiple tables using a singleDROP TABLE
statement, each table is separated by a comma (,). - The
TEMPORARY
option allows you to remove temporary tables only. It ensures that you do not accidentally remove non-temporary tables. - The
IF EXISTS
option conditionally drop a table only if it exists. If you drop a non-existing table with theIF EXISTS
option, MySQL generates a NOTE, which can be retrieved using theSHOW WARNINGS
statement. - Note that the
DROP TABLE
statement only drops tables. It doesn’t remove specific user privileges associated with the tables. 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. RESTRICT | CASCADE
: These are optional keywords that specify what should happen if other tables have foreign key references to the table you're trying to delete.RESTRICT
prevents the deletion of the table if there are any references, whileCASCADE
deletes the table and any rows in other tables that reference it.
