Altering Tables ( Drop Tables )

DROP TABLE removes one or more tables. All table data and the table definition are  removed, so  be careful with this statement!   DROP [TEMPORARY] TABLE [IF EXISTS] table1;  Use IF EXISTS to prevent an error from occurring for tables that do not exist. An error is generated for each non-existent table when using IF EXISTS. The TEMPORARY keyword has the following effects:               1.  The statement drops only TEMPORARY tables.               2.  The statement does not end an ongoing transaction Using TEMPORARY is a good way to ensure that non-TEMPORARY table is not deleted by accident. DROP TABLE examples:  DROP TABLE table1;  DROP TABLE IF EXISTS table1;  DROP TEMPORARY TABLE eu_countries_temp;
