SPI_keepplan — save a prepared statement


int SPI_keepplan(SPIPlanPtr plan)


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.


SPIPlanPtr plan

the prepared statement to be saved

Return Value

0 on success; SPI_ERROR_ARGUMENT if plan is NULL or invalid


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.
