+
+ ON COMMIT
+
+ The behavior of temporary tables at the end of a transaction
+ block can be controlled using ON COMMIT.
+ The three options are:
+
+
+
+ PRESERVE ROWS
+
+ No special action is taken at the ends of transactions.
+ This is the default behavior.
+
+
+
+
+
+ DELETE ROWS
+
+ All rows in the temporary table will be deleted at the end
+ of each transaction block. Essentially, an automatic
+ linkend="sql-truncate" endterm="sql-truncate-title"> is done
+ at each commit.
+
+
+
+
+
+ DROP
+
+ The temporary table will be dropped at the end of the current
+ transaction block.
+
+
+
+
+
+
+
+
+
+ TABLESPACE tablespace
+
+ The tablespace is the name
+ of the tablespace in which the new table is to be created.
+ If not specified,
+ is used, or the database's
+ default tablespace if default_tablespace is an empty
+ string.
+
+
+
+
query
CREATE TABLE films_recent AS
SELECT * FROM films WHERE date_prod >= '2002-01-01';
+
+
+
+ Create a new temporary table that will be dropped at commit
+ films_recent with oids consisting of only
+ recent entries from the table films using a
+ prepared statement:
+
+PREPARE recentfilms(date) AS
+ SELECT * FROM films WHERE date_prod > $1;
+CREATE TEMP TABLE films_recent WITH OIDS ON COMMIT DROP AS
+ EXECUTE recentfilms('2002-01-01');
-
- The standard defines an ON COMMIT clause;
- this is not currently implemented by
PostgreSQL.-
-
-
The standard defines a WITH [ NO ] DATA clause;
for details.
+
+
+ The
PostgreSQL concept of tablespaces is not
+ part of the standard. Hence, the clause TABLESPACE
+ is an extension.
