MariaDB: DROP TABLE Statement
This MariaDB tutorial explains how to use the MariaDB DROP TABLE statement with syntax and examples.
Description
The MariaDB DROP TABLE statement allows you to remove or delete a table from the MariaDB database.
Syntax
In its simplest form, the syntax for the DROP TABLE statement in MariaDB is:
DROP TABLE table_name;
However, the full syntax for the MariaDB DROP TABLE statement is:
DROP [ TEMPORARY ] TABLE [ IF EXISTS ] table_name1, table_name2, ... [ RESTRICT | CASCADE ];
Parameters or Arguments
- TEMPORARY
- Optional. It specifies that only temporary tables should be dropped by the DROP TABLE statement.
- table_name
- The name of the table to remove from the database.
- table_name1, table_name2
- The tables to remove from the database, if removing more than one table in the DROP TABLE statement.
- IF EXISTS
- Optional. If specified, the DROP TABLE statement will not raise an error if one of the tables does not exist.
- RESTRICT
- Optional. It has no impact or effect on the DROP TABLE statement but is included in the syntax to make porting the tables to different databases easier.
- CASCADE
- Optional. It has no impact or effect on the DROP TABLE statement but is included in the syntax to make porting the tables to different databases easier.
Note
- If you use the MariaDB DROP TABLE statement to drop one or more tables that do not exist, the database will raise an error (unless you specify the IF EXISTS parameter in the DROP TABLE statement).
Example
Let's look at an example that shows how to drop a table using the MariaDB DROP TABLE statement.
Drop One Table
First, let's look at a simple DROP TABLE example that shows how to use the DROP TABLE statement to drop one table in MariaDB.
For example:
DROP TABLE websites;
This DROP TABLE example would delete the table called websites.
Drop Multiple Tables
Let's look at an example where we want to drop more than one table using the DROP TABLE statement:
For example:
DROP TABLE websites, stats;
This DROP TABLE statement example would delete two tables - websites and stats. If we were worried that one of the tables doesn't exist and we don't want to raise an error, we could modify our DROP TABLE statement as follows:
DROP TABLE IF EXISTS websites, stats;
This example would delete the websites and stats tables and would not raise an error if one of the tables didn't exist.
Drop Temporary Table
Finally, let's look at an example that shows how to use the DROP TABLE statement to drop a temporary table.
DROP TEMPORARY TABLE IF EXISTS page_loads;
This DROP TABLE example will only delete the temporary table called page_loads. If there was also a permanent table called page_loads, this DROP TABLE statement would not delete it because TEMPORARY is specified.
