Subj:   Hash Join Vs Merge Join
 
From:   Kambhoji, Naveen

Hello,

I am not sure I understand the difference between Hash Join and Merge Join. How do we enable Hash joins and in what situations Hash join takes place?


Also I am trying a SQL like below

     SELECT ROUND(195.89,0)

Its giving error as

The user doesnt have the EXECUTE FUNCTION access to syslib.RoundDec8


Can someone tell me what it mean, I tried the same in both BTEQ and QUERYMAN.


Appreciate your help,

Naveen.
