Try REORGing the tablespace as well. It will then unload the data, sort it and load it back in the correct order. Try that and see what you get.

Hello,

when i queried the table the rows fetched were out of order
Sorry, but no. . .

If you do not specify an ORDER BY, there is no "out of order". If you want rows returned in a particular order, you need to specify this in your query.
Hope this helps,
d.sch.
