Expressions passed to this function must have one of the following data types:

CHAR, VARCHAR, or CLOB

You can also pass arguments with data types that can be converted to the above types using the implicit data type conversion rules that apply to UDFs.

The UDF implicit type conversion rules are more restrictive than the implicit type conversion rules normally used by Vantage. If an argument cannot be converted to the required data type following the UDF implicit conversion rules, it must be explicitly cast.
