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

  • date_value = DATE, TIMESTAMP, or TIMESTAMP WITH TIME ZONE
  • fmt = VARCHAR

For the fmt argument, you can also pass values with data types that can be converted to VARCHAR using the implicit data type conversion rules that apply to UDFs. Implicit type conversion is not supported for the date_value argument.

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.
