Hashed File
Posted: Thu Oct 31, 2002 10:50 pm
Hi All,
I have some doubts regarding Hashed File. In Datastage Ver4, Key column is a must in column definition otherwise it will give the message box saying "Key column should be selected" and it wont allow the users to press OK button without key column. But in DataStage Ver 5 and V6, it is not explicitily asking for the Key column. Even if there is no key column, it is accepting. Can anyone explain abt this in detail???
One more thing, I want to know the basic difference between Universe Table and Hashed File.
Also, what is difference between key column in between these two??? Because, I have created a Universe table and I am able to access the same table thro hashed file stage. So, I want to know the differenc ein detail. Can anyone throw light on this???
Thanks in advance,
Bala
