SPI_execute_plan — execute a plan prepared by SPI_prepare
int SPI_execute_plan(void *plan, Datum *values, const char *nulls, boolread_only, longcount)
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 * valuesAn array of actual parameter values. Must have same length as the plan's number of arguments.
const char * nulls An array describing which parameters are null. Must have same length as
the plan's 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 countmaximum 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.
