Home -> Community -> Usenet -> c.d.o.misc -> Re: Substitution of column names
try:
select fund, orgn, acct,
decode( :UserInput, 1, total_01_budg,
2, total_02_budg,
3, total_03_budg,
.....
12, total_12_budg ) total_budg
from mytable
Bind in the value for UserInput when you open the cursor. decode is sort of like a case statement in sql....
