Teradata Vantage™

You can invoke an SQL UDF from embedded SQL requests in the same way you would invoke an SQL UDF from an interactive SQL request. Other than restrictions that apply to the use of SQL expressions in an embedded SQL program (see Teradata Vantage™ - SQL Stored Procedures and Embedded SQL, B035-1148) you can invoke SQL UDFs from an embedded SQL request without any restrictions.

The following example shows one possible way to invoke an SQL UDF, in this case common_value_expression, from an embedded SQL request.

EXEC SQL FOR 19
  INSERT INTO t1
  VALUES (:var1, df2.common_value_expression(:var2, 2), :var3);
