Example: Displaying a Java UDF with Array and Period Data Types - Teradata Vantage

This statement creates a user defined type named phonenumbers_ary as an array:

CREATE TYPE phonenumbers_ary AS CHAR(10) ARRAY[5];

This statement creates a user defined type named MYINT as an integer:

CREATE TYPE MYINT AS INTEGER FINAL;

The UDF is created using phonenumber_ary and Period(date) type parameters and returns a MYINT type value.

CREATE FUNCTION getPhoneNums(parameter_1 phonenumber_ary,
                  parameter_2 Period(Date))
        RETURNS MYINT
        LANGUAGE JAVA
        NO SQL
        PARAMETER STYLE JAVA 
        EXTERNAL NAME 
        'UDF_JAR:UserDefinedFunctions.getPhoneNums';

Following is an example of HELP FUNCTION for a Java UDF:

HELP FUNCTION getPhoneNums;

Result:

*** Help information returned. 3 rows.
 *** Total elapsed time was 1 second.
