SPI_execp — execute a statement in read/write mode
int SPI_execp(SPIPlanPtrplan, Datum *values, const char *nulls, longcount)
SPI_execp is the same as SPI_execute_plan, with the latter's read_only parameter always taken as false.
SPIPlanPtr planprepared statement (returned by SPI_prepare)
Datum * valuesAn array of actual parameter values. Must have same length as the statement's number of arguments.
const char * nullsAn array describing which parameters are null. Must have same length as the statement's number of arguments.
If nulls is NULL then SPI_execp assumes that no parameters are null. Otherwise, each entry of the nulls array should be ' ' if the corresponding parameter value is non-null, or 'n' if the corresponding parameter value is null. (In the latter case, the actual value in the corresponding values entry doesn't matter.) Note that nulls is not a text string, just an array: it does not need a '\0' terminator.
long countmaximum number of rows to return, or 0 for no limit

SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
