Oracle Query results to be stored in variables
Hi

I would like to know if there is a way to just have one ORACLE connection established, using which we can execute different queries and store the results under different variables.

For e.g the following uses to two silent ORACLE connection to store the result under two different variables. Instead can we just be able to modify the code to use the same connection against multiple queries?

#!/bin/bash
Query1=`sqlplus -s user/pwd@host<<eof
set serveroutput on;
set feedback off;
set linesize 1000;
select name from success; --Just for e.g.
EXIT;
eof`
....Operation on $Query1

Query2=`sqlplus -s user/pwd@host<<eof
set serveroutput on;
set feedback off;
set linesize 1000;
select name from failure; --Just for e.g.
EXIT;
eof`
....Operation on $Query2

The reason for asking is that the same code is required to be repeated multiple times.

Also, can you pls explain how to read the results stored in the variable line by line.

For e.g.

if Query1 results are:

int1
int4
int5

I would like to be able to get int1 value first, get the second one int4 and get the last one int5. Just would like to know how to perform a loop and read each line.

Thanks for your help.
Ashok

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.

SEE ALSO

       tcp-environ(5), inetd(8)

                                                                                                                                        tcp-env(1)
