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.
count have the same interpretation as in
prepared statement (returned by
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
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_tuptable are set as in
SPI_execute if successful.
