int SPI_execute_plan(void * plan, Datum * values, const char * nulls, bool read_only, int count)
SPI_execute_plan executes a plan
SPI_prepare. read_only and count
have the same interpretation as in
execution plan (returned by
An array of actual parameter values. Must have same length as the plan's number of arguments.
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.
true for read-only execution
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:
if plan is NULL or count is less than 0
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
SPI_execute_plan for this plan
will be unpredictable.
