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.
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.
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.
