A.7.3. TEMPORARY TABLE Problems

The following list indicates limitations on the use of TEMPORARY tables:

  • A TEMPORARY table can only be of type HEAP, MyISAM, MERGE, or InnoDB.

  • You cannot refer to a TEMPORARY table more than once in the same query. For example, the following does not work:

    mysql> SELECT * FROM temp_table, temp_table AS t2;
    ERROR 1137: Can't reopen table: 'temp_table'
    
  • The SHOW TABLES statement does not list TEMPORARY tables.

  • You cannot use RENAME to rename a TEMPORARY table. However, you can use ALTER TABLE instead:

    mysql> ALTER TABLE orig_name RENAME new_name;
    
  • There are known issues in using temporary tables with replication. See Section 6.8, “Replication Features and Known Problems”, for more information.
