Create a temporary table in a MySQL procedure?

To create a temporary table in a MySQL procedure, following is the syntax −

CREATE PROCEDURE yourProcedureName()    BEGIN       CREATE TEMPORARY TABLE yourTemporaryTableName SELECT yourValue;    END

Let us implement the above syntax to create a temporary table and insert some records in the table. Following is the query to create a stored procedure and a temporary table in it −

mysql> DELIMITER // mysql> CREATE PROCEDURE create_Temporary_Table()    -> BEGIN    ->    CREATE TEMPORARY TABLE tmpDemoTable SELECT 500;    -> END// Query OK, 0 rows affected (0.15 sec)

Following is the query to insert record in the table −

mysql> CREATE PROCEDURE insert_Record_InTempTable()    -> BEGIN    ->    INSERT INTO tmpDemoTable VALUES (300);    -> END// Query OK, 0 rows affected (0.06 sec)

mysql> DELIMITER

Now you can call the above stored procedure to create a temporary table −

mysql> call create_Temporary_Table(); Query OK, 1 row affected (0.00 sec) mysql> call insert_Record_InTempTable(); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select *from tmpDemoTable;

Output

This will produce the following output −

+-----+ | 500 | +-----+ | 500 | | 300 | +-----+ 2 rows in set (0.00 sec)
