Subj:   OR in a WHERE clause
 
From:   Rudel Simard

Hi everybody,

We using Impromptu catalog with our Teradata. The report, the user does, generate a SQL including a OR in the WHERE clause. I know the Teradata ignore the NUPI with a OR.

Does anybody have a idea how force Impromptu to create a good SQL to use the NUPI of the Teradata.

     SELECT  T1.COL1 (NAMED "c1" ) ,
                     T2.COL2 (NAMED "c2" )

     FROM
         "TABLE2" T2 LEFT OUTER JOIN "TABLE1" T1 ON
          T2."COL3" = T1."COL4")

     WHERE   (1 = 1 AND 25113 = T2.COL5_NUSI OR
             1 = 2 AND 25113 = T1.COL6_NUSI  ) AND
             T2.COL7_NUSI BETWEEN 990101 AND 991231

Thank you for your help,
