The result type returned by the external function that is to be converted to the type specified by the RETURNS clause.

Example:

  ...RETURNS DECIMAL(9,5) CAST FROM FLOAT...

Whenever a LOB that requires data type conversion is passed to an external UDF, the LOB must first be materialized for the conversion to take place.

The value for data_type can be a UDT.

You cannot specify a character server data set attribute of KANJI1. Otherwise, Teradata Database returns an error to the requestor.
