DECLARE TEMPORARY TABLE statement allows you to define a temporary table for the current session.

Syntax:

DECLARE [GLOBAL] TEMPORARY TABLE table_name
(
   column_name data_type [NULL | NOT NULL]
   [, ...]
)
[ ON COMMIT DELETE ROWS | ON COMMIT PRESERVE ROWS]

The following options are supported for compatibility with other databases:

IBM DB2:

IN tablespace_name
WITH REPLACE
DISTRIBUTE BY HASH (col, ...) 
LOGGED | NOT LOGGED

For more details how temporary table support is implemented in HPL/SQL, see Native and Managed Temporary Tables.

Example:

Create a managed temporary table and use it in other SQL statements:

SET hplsql.temp.tables = managed;
 
DECLARE TEMPORARY TABLE temp1
(
   c1 INT,
   c2 STRING
);
 
INSERT INTO temp1 SELECT 1, 'A' FROM dual;
 
SELECT * FROM temp1;

Compatibility: IBM DB2

Version: HPL/SQL 0.03
