Sorry,I found the problem of this,there was a "union" keyword being used,so it was the problem,this is fixed by adding "all" like "union all". – user1495475 Nov 05 '12 at 07:23

But is `union all` what you realley need ? – A.B.Cade Nov 05 '12 at 08:19

@A.B.Cade:No,i needed "dbms_lob.getlength" to be used to a CLOB column. – user1495475 Nov 05 '12 at 09:56

`union all` is not like `union` (http://stackoverflow.com/a/49928/1083652). Are you sure that changing the `union` keyword to `union all` gives you correct results? – A.B.Cade Nov 05 '12 at 11:09
