Returns a value that indicates whether the arguments to the table function are constant or vary.

Value Meaning
Tbl.TBL_MODE_CONST The table UDF arguments are constant. The SELECT statement invoked the table function with constant expression input arguments.
Tbl.TBL_MODE_VARY The table UDF arguments vary and are based on the rows produced by the correlated table specification in the SELECT statement.

The table UDF might only be called on specific AMP vprocs in this mode.
