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 plan prepared 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 count maximum number of rows to return,
or 0 for no limit
See SPI_execute_plan.
SPI_processed and
SPI_tuptable are set as in
SPI_execute if successful.
