SPI_KEEPPLAN(3) 		  PostgreSQL 9.2.7 Documentation		  SPI_KEEPPLAN(3)

NAME
       SPI_keepplan - save a prepared statement

SYNOPSIS
       int SPI_keepplan(SPIPlanPtr plan)

DESCRIPTION
       SPI_keepplan saves a passed statement (prepared by SPI_prepare) so that it will not be
       freed by SPI_finish nor by the transaction manager. This gives you the ability to reuse
       prepared statements in the subsequent invocations of your procedure in the current
       session.

ARGUMENTS
       SPIPlanPtr plan
	   the prepared statement to be saved

RETURN VALUE
       0 on success; SPI_ERROR_ARGUMENT if plan is NULL or invalid

NOTES
       The passed-in statement is relocated to permanent storage by means of pointer adjustment
       (no data copying is required). If you later wish to delete it, use SPI_freeplan on it.
