SPI_execute_plan - execute a plan prepared by SPI_prepare
int SPI_execute_plan(void * plan, Datum * values, const char * nulls, bool read_only, long count)
SPI_execute_plan executes a plan prepared by SPI_prepare. read_only and count have the same interpretation as in SPI_execute.
void * plan execution plan (returned by SPI_prepare) Datum * values An array of actual parameter values. Must have same length as the plans number of arguments. const char * nulls An array describing which parameters are null. Must have same length as the plans number of arguments. 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_execute_plan assumes that no parameters are null.
bool read_only true for read-only execution long count maximum number of rows to process or return
The return value is the same as for SPI_execute, with the following additional possible error (negative) results:
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_execute if successful.
If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the result of SPI_execute_plan for this plan will be unpredictable.
