Beginning with ODBC Driver for Teradata Release 14.10, scalar functions had to be used within escape sequences. This restriction is removed. Scalar functions can be used without escape sequences because Teradata Database natively supports them. In addition, ODBC Driver for Teradata now supports the following scalar functions:
