Oops.. i have another problem here if it is just a normal sql statement it will work but however when i create this with a view it give me error...

"create view test as select * from tablename fetch first 5 rows only"

and the error saying :

DB21034E  The command was processed as an SQL statement because it was not a valid Command Line Processor command.  During SQL processing it returned:
SQL0104N  An unexpected token "from tablename" was found following "iew test as
select *".  Expected tokens may include:  "<space>".  SQLSTATE=42601

so wat is the problem now? :-(

I suspect you can't do this in a view.
you need the select in the view and the fetch in the sql statement.

In sql server I never use views as they are not necessary as you have SPs. I believe they are in Oracle - don't know about DB2.
