RE: SQL Question

If I
remember correctly it would be executed once for every resulting row.
if
you placed it in the where clause it would be diffierent.

  Good morning,
 

  Env't:  Oracle 8.1.5, HP-UX 11.0 (64
  bit)
 

  Given the following tables:
  emp with 100 rows
  dept with 10 rows
 

  and this SQL:
  select emp.ename,
  initcap(dept.deptname)
  from emp.dept
  where emp.deptno = emp.deptno;
 

  The questions -
  How many times is the initcap(dept.deptname)   function actually "executed"?
  Is it once for each emp row (100 times) or once   for each dept row (10 times) or some other value?
 

  Another scenario -
  Would it be faster to retrieve rows with a   bunch of similar functions (initcap, concatenations of columns and/or   literals, etc) or to have and maintain the data in columns with the data   formatted as such?
 

  TIA gurus...
