SPI_execute_plan − execute a plan prepared by SPI_prepare
int
SPI_execute_plan(void * plan, Datum * values,
const char * nulls,
bool read_only, long count)
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 * values
An 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 count
maximum 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.
If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the result of SPI_execute_plan for this plan will be unpredictable.
