SPI_SAVEPLAN(3) PostgreSQL 9.1.9 Documentation SPI_SAVEPLAN(3)NAMESPI_saveplan - save a plan
SYNOPSIS
SPIPlanPtr SPI_saveplan(SPIPlanPtr plan)
DESCRIPTIONSPI_saveplan saves a passed plan (prepared by SPI_prepare) in memory
that will not be freed by SPI_finish nor by the transaction manager,
and returns a pointer to the saved plan. This gives you the ability to
reuse prepared plans in the subsequent invocations of your procedure in
the current session.
ARGUMENTS
SPIPlanPtr plan
the plan to be saved
RETURN VALUE
Pointer to the saved plan; NULL if unsuccessful. On error, SPI_result
is set thus:
SPI_ERROR_ARGUMENT
if plan is NULL or invalid
SPI_ERROR_UNCONNECTED
if called from an unconnected procedure
NOTES
The passed-in plan is not freed, so you might wish to do SPI_freeplan
on it to avoid leaking memory until SPI_finish.
If one of the objects (a table, function, etc.) referenced by the
prepared plan is dropped or redefined, then future executions of
SPI_execute_plan may fail or return different results than the plan
initially indicates.
