Select columns into local variable from sql script using shell script

im trying to write a unix script that will retrieve a parameter using sql query and run a script afterwards with this parameter.
for the time being, im just tryin to make it echo the retrieved parameter.
the sql query that works fine on toad (oracle 8) is :

select billcycle from bc_run
where billcycle not in (50,16)
and control_group_ind is null
and billseqno=6043    

the above query give a number.

now the script i wrote is:

#!/bin/bash

echo "this script will print the billcycle date"

v_bc=`sqlplus -s /@bscsprod <<EOF
select billcycle from bc_run
where billcycle not in (50,16)
and control_group_ind is null
and billseqno=6043`

echo "billcycle number is $v_bc" 

the result when i run the file is

billcycle number is

with no number that follows.

any ideas what’s wrong ? maybe the syntax for connecting to the sql server ?

thanks
Assaf.

Answer 1

The duplicate question APC linked to shows a working example, but to clarify you have two problems. The first is non-fatal and is just that you don’t have EOF, as Rembunator pointed out (though it’s in the wrong place in that answer).

More importantly though you don’t have a terminating ; in your query, so SQL*Plus won’t execute it – it just exits with no output.

If you typed your original query in as the SQL*Plus command prompt it would leave you at a further prompt waiting for input, and then go back to a normal prompt if you just hit return again, without actually executing the query:

SQL> select billcycle from bc_run
  2  where billcycle not in (50,16)
  3  and control_group_ind is null
  4  and billseqno=6043
  5
SQL> 

You also probably want at least some formatting of the output. So this should work:

v_bc=`sqlplus -s /@bscsprod <<EOF
set pagesize 0
select billcycle from bc_run
where billcycle not in (50,16)
and control_group_ind is null
and billseqno=6043;
EOF`
