SPI_keepplan
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 C function in the current session.
Arguments
-
SPIPlanPtrplan -
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.
