Code:
#!/bin/ksh
>example.sql
cat example.dat | while read NUMBER
do
        sed -e "s/DATA/${NUMBER}/g" example.skl >> example.sql
done

sorry but after running the command the example.sql file is getting empty. If i remove the part
>example.sql
and run it it works but replacing NUMBER with each DATA on each line , not replacing with the real numbers.
