====== DECLARE TEMPORARY TABLE ====== DECLARE TEMPORARY TABLE statement allows you to define a temporary table for the current session. **Syntax**: <code language=sql> DECLARE [GLOBAL] TEMPORARY TABLE table_name ( column_name data_type [NULL | NOT NULL] [, ...] ) [ ON COMMIT DELETE ROWS | ON COMMIT PRESERVE ROWS] </code> ==== Compatibility Options ==== The following options are supported for compatibility with other databases: **IBM DB2:** <code language=sql> IN tablespace_name WITH REPLACE DISTRIBUTE BY HASH (col, ...) LOGGED | NOT LOGGED </code> For more details how temporary table support is implemented in HPL/SQL, see [[temporary-tables|Native and Managed Temporary Tables]]. **Example**: Create a managed temporary table and use it in other SQL statements: <code language=sql> SET hplsql.temp.tables = managed; DECLARE TEMPORARY TABLE temp1 ( c1 INT, c2 STRING ); INSERT INTO temp1 SELECT 1, 'A' FROM dual; SELECT * FROM temp1; </code> **Compatibility:** IBM DB2 **Version**: HPL/SQL 0.03 See also: * [[temporary-tables|Native and Managed Temporary Tables]] * [[create-local-temporary-table|CREATE LOCAL TEMPORARY TABLE]] * [[create-volatile-table|CREATE VOLATILE TABLE]] ~~NOTOC~~
