Hello,

Cheking with HEX ON, i found that they were null charecters.

There is no such thing as a "null character". . . The Null Indicator might be set, but no value from x'00' to x'FF' is a null value - every value is valid as data. . .

You still have not posted some data in HEX with the "Code" tag. . .

With a left outer join it is possible that some columns are null, even when defined not null in the table.

Hence dsntiaul will generate place for those null indicators
