SPI_execute_plan — execute a statement prepared by SPI_prepare
int SPI_execute_plan(SPIPlanPtrplan, Datum *values, const char *nulls, boolread_only, longcount)
SPI_execute_plan executes a statement prepared by
SPI_prepare or one of its siblings.
read_only and
count have the same interpretation as in
SPI_execute.
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_execute_plan 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.
bool read_onlytrue for read-only execution
long count
maximum number of rows to return,
or 0 for no limit
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 invalid,
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.
