Connecting from UNIX

Question

I need to connect to oracle from UNIX by a script. I need the script to prompt for a variable and that variable to be used for dml in sql statment but not able to do so..
Script 1 will be something like this
#!/bin/bash
USER=$1
PASSWD=$2
DB=$3
exec >output/$DB$USER.out 2>&1
sqlplus ${USER}/${PASSWD}@${DB} << THEEND
set serveroutput on;
set pages 0;
set lines 32000;
start $4
quit
THEENDdone
wait
The parameter $4 will be calling a sql script (.sql) where i want to prompt and accept few variables
PROMPT Tracking ID of product to be ended
ACCEPT v_ti NUMBER PROMPT "Tracking ID: "
SELECT *
FROM products
WHERE tracking_id = &v_ti ;
But this is not working as script comes out without prompting for variable..
Any help ?

Answer 1

Just did a quick test and it only seems to have the issue when getting the script from STDIN. If you pass it a file "sqlplus user/pass@db @myscript.sql" then it will wait for the input. So if it's going to be a wrapper for scripts you should have no problems, otherwise you will have to cat your script into a temp file and then call sqlplus.
Hope that helps
