Description
SPI_execp
executes a plan prepared by SPI_prepare.
tcount has the same
interpretation as in SPI_exec.
Usage
If nulls
is NULL then
SPI_execp
assumes that all parameters (if any) are NOT NULL.
Note: If one of the objects (a relation, function, etc.) referenced by the prepared
plan is dropped during your session (by your backend or another process) then the
results of SPI_execp for this plan will be unpredictable.
