int SPI_execute_plan(SPIPlanPtr plan, Datum * values, const char * nulls,
bool read_only, long count)
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.
prepared statement (returned by SPI_prepare)
An array of actual parameter values. Must have same length as the statement's number of arguments.
An array describing which parameters are null. Must have same length as the statement'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 return, or 0 for no limit
The return value is the same as for SPI_execute, with the following additional
possible error (negative) results:
if plan is NULL or invalid, 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.
