SPI_execp -- executes a plan prepared by SPI_prepare
Synopsis
int SPI_execp(void * plan, Datum * values, const char * nulls, int count)
Description
SPI_execp executes a plan prepared by SPI_prepare. tcount has the same interpretation as in SPI_exec.
Arguments
void * plan
execution plan (returned by SPI_prepare)
Datum *values
actual parameter values
const char * nulls
An array describing which parameters are null. n indicates a null value (entry in values will be ignored); a space indicates a nonnull value (entry in values is valid).
If nulls is NULL then SPI_execp assumes that no parameters are null.
int count
number of row for which plan is to be executed
Return Value
The return value is the same as for SPI_exec or one of the following:
SPI_ERROR_ARGUMENT
if plan is NULL or count is less than 0
SPI_ERROR_PARAM
if values is NULL and plan was prepared with some parameters
SPI_processed and SPI_tuptable are set as in SPI_exec if successful.
Notes
If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the result of SPI_execp for this plan will be unpredictable.
