Example: USING Request Modifier - Teradata Database - Teradata Vantage NewSQL Engine

In this example, the USING request modifier establishes three variable parameters whose constant values are used both for data input and as WHERE clause predicates in a multistatement request:

     .SET RECORDMODE ON
     .IMPORT DATA FILE = r13sales.dat;

     USING (var_1 CHARACTER, var_2 CHARACTER, var_3 CHARACTER)
     INSERT INTO testtabu (c1) VALUES (:var_1)
    ;INSERT INTO testtabu (c1) VALUES (:var_2)
    ;INSERT INTO testtabu (c1) VALUES (:var_3)
    ;UPDATE testtabu
       SET c2 = c1 + 1
       WHERE c1 = :var_1
    ;UPDATE testtabu
       SET c2 = c1 + 1
       WHERE c1 = :var_2
    ;UPDATE testtabu
       SET c2 = c1 + 1
       WHERE c1 = :var_3;
