Subj:   UDF + NOT EXISTS + CASE
 
From:   Shaju Kodian

When I am using user defined function in CASE statement along with NOT EXISTS clause teradata gives strange error 3610. Where as this same function used with different combination i.e. either one, NOT EXISTS or CASE statement, if not used, it works.

Below I have pasted the query as well as error, where 'lpad' is the function which simulates Oracle's 'LPAD'.

There is no problem with the UDF. It works very well.

This behaviour I am finding only, when UDF is used in 'CASE' which is within 'NOT EXISTS' clause.

Can anybody justify ?

     SELECT    *
     FROM      taoa
     WHERE     NOT EXISTS
               (
               SELECT    1
               FROM      tas01
               WHERE     taoa.oan  =    CASE
                                             WHEN taoa.appli_cd = '80' THEN
                                                  ( lpad( COALESCE( CAST(
     CAST( tas01.pinsuper AS INTEGER) AS VARCHAR(5) ), '' ), 5, '0') )
                                                  || ( COALESCE(
     tas01.pintycon, '' ) )
                                             ELSE
                                                  '90000' || ( COALESCE(
     tas01.pintycon, '' ) )
                                        END
               )
