SPI_keepplan

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.
