depending on what exactly you want do AND what exactly separates your columns...

Code:
#!/bin/ksh
while read c1 c2
do
   echo "column1->[${c1}] column2->[${c2}]"
done < myTableFile

Smilie Are you trying to read from a database table or a flat file? My guess is that you are trying to read for a database table.

If so, use a coprocessor to control your query to the row level. Here is a link that may help.
