An extended version of FNC_GetPhase that provides additional options for variable mode table functions.
FNC_GetPhaseEx returns an FNC_Mode value that indicates whether the arguments to the table function are constant or vary.
FNC_Mode is defined as:
typedef enum FNC_Mode
{
TBL_MODE_VARY = 1,
TBL_MODE_CONST = 2
} FNC_Mode;
| This value … | Means that the table function arguments … |
|---|---|
| TBL_MODE_CONST | are constant. |
| TBL_MODE_VARY | vary and are based on the rows produced by the correlated table specification in the SELECT statement. The table function might only be called on specific AMP vprocs in this mode. |
