If Vantage invokes a function that defines compatible parameter types, but not exact parameter types, input arguments are converted to the type expected in the function definition.
UDF arguments do not follow the implicit type conversion rules that permit the assignment and comparison of some types without requiring explicit conversion. For example, Vantage implicitly converts DATE types to numeric types for assignment.
If the arguments of the calling function are not compatible with an existing function, they must be explicitly cast to the proper type.
Vantage does not perform implicit data type conversions for TD_ANYTYPE parameters.
