You request involves alot of stuff; the first thing that you need to do is search the forums for "sqlplus". This will help you get the best start in the right direction.

your shell script may look like this

//to read from file
cat filename |while read line
//do some thing
//create sql script
echo "sql command" >>query.sql
//connect to database
sqlplus username/password@query.sql<<STOP

Just be careful with comments. Proper shell comments are with the # character, not //.

Do it all in PL/SQL


EXIT WHEN End of file

Perform update using TradeNo
