int SPI_execute_plan(void * plan, Datum * values, const char * nulls, bool read_only, int count)
SPI_execute_plan executes a plan prepared by SPI_prepare. read_only and count have the same interpretation as in SPI_execute.
execution plan (returned by SPI_prepare)
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 of SPI_execute_plan for this plan will be unpredictable.
