SPI_execp — execute a statement in read/write mode
int SPI_execp(SPIPlanPtrplan, Datum *values, const char *nulls, longcount)
SPI_execp is the same asSPI_execute_plan, with the latter'sread_only parameter always taken asfalse.
SPIPlanPtrplanprepared statement (returned bySPI_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.
Ifnulls isNULL thenSPI_execp assumes that no parameters are null. Otherwise, each entry of thenulls 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 correspondingvalues entry doesn't matter.) Note thatnulls is not a text string, just an array: it does not need a'\0' terminator.
longcountmaximum number of rows to return, or0 for no limit

SPI_processed andSPI_tuptable are set as inSPI_execute if successful.
