I have the following expression in ssis
(ISNULL [rowguid]? (DT_WSTR, 255)"00000000-0000-0000-0000-000000000000":[rowguid])
What I want is to assign that guid if there is null present. I just can't seem to get it working
FInally got the answer via trail and error
(DT_STR,50,1252) (ISNULL( [rowguid]) ? "00000000-0000-0000-0000-000000000000" : (DT_STR,50,1252) [rowguid]) != (DT_STR,50,1252) (ISNULL( [rowguid]) ? "00000000-0000-0000-0000-000000000000" : (DT_STR,50,1252) [rowguid])
