Subj:   Parallel processing
 
From:   Jim Downey

Suppose I want to generate a list of values for each column on a table. Which is less intrusive to the environment:

Run each query in series.
Select c1 from t1 group by 1;
Select c2 from t1 group by 1;
Select c3 from t1 group by 1;

Run as a multistatement request (presumably in parallel taking advantage of a synchronized scan)?

Select c1 from t1 group by 1
;Select c2 from t1 group by 1
;Select c3 from t1 group by 1
;


Thanks

Jim
