Example: Setting the Transaction Query Band Using a Parameter - Teradata Vantage - Analytics Database

Both of the following procedures set the transaction query band using a parameter named qbin:

     CREATE PROCEDURE setqbmsr(
       IN qbin VARCHAR(60))
      BEGIN REQUEST
        SET QUERY_BAND = :qbin FOR TRANSACTION;
        INS abc(1,2);
      END REQUEST;

     CREATE PROCEDURE qbparm1 (
       IN  par1 INTEGER,
       IN  qbin VARCHAR(60),
       OUT qbout VARCHAR(60))
      BEGIN REQUEST
       BEGIN TRANSACTION;
        SET QUERY_BAND = :qbin FOR TRANSACTION;
        SELECT GetQueryBand() INTO qbout;
       END TRANSACTION;
      END REQUEST;

Result:

     CALL qbparm1(10, 'kid=kate;', par3);
       *** Procedure has been executed. 
       *** Total elapsed time was 1 second.
     qbout
