Hi Michael,

I was thinking why one SQL works while the other doesn't? I even tried doing the TRIM after converting the data type (as you suggested) but that still doesn't explains the behavior. I pasted the explains as I saw some difference in the optimizer plan in the two cases, however that doesn't explains why one case is working while the other is failing!

     sel *
     From tt1,t1
     Where TRIM (tt1.a (varchar(10))) =t1.a;

     CREATE SET TABLE tt1
          (
           a INTEGER,
           b INTEGER)
     UNIQUE PRIMARY INDEX ( a );

     CREATE SET TABLE t1
          (
           a VARCHAR(5) CHARACTER SET LATIN NOT CASESPECIFIC,
           b CHAR(5) CHARACTER SET UNICODE NOT CASESPECIFIC)
     PRIMARY INDEX ( a );


     sel * From tt1,t1;

          a     b     a     b
          1     1     1     1

Thanks, Vivek
