4 SPI_execute_plan — execute a statement prepared by SPI_prepare
8 int SPI_execute_plan(SPIPlanPtr plan, Datum * values, const char * nulls,
9 bool read_only, long count)
13 SPI_execute_plan executes a statement prepared by SPI_prepare or one of
14 its siblings. read_only and count have the same interpretation as in
20 prepared statement (returned by SPI_prepare)
23 An array of actual parameter values. Must have same length as
24 the statement's number of arguments.
27 An array describing which parameters are null. Must have same
28 length as the statement's number of arguments.
30 If nulls is NULL then SPI_execute_plan assumes that no
31 parameters are null. Otherwise, each entry of the nulls array
32 should be ' ' if the corresponding parameter value is non-null,
33 or 'n' if the corresponding parameter value is null. (In the
34 latter case, the actual value in the corresponding values entry
35 doesn't matter.) Note that nulls is not a text string, just an
36 array: it does not need a '\0' terminator.
39 true for read-only execution
42 maximum number of rows to return, or 0 for no limit
46 The return value is the same as for SPI_execute, with the following
47 additional possible error (negative) results:
50 if plan is NULL or invalid, or count is less than 0
53 if values is NULL and plan was prepared with some parameters
55 SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
