Try this
Code:
$ cat x
#!/bin/ksh

##  The command in $() returns COUNT=<nbr> which is then eval'd to create
##  and set a shell variable called COUNT. There is a carriage return after the
##  set heading off; command.
eval $(print "set heading off;
select 'COUNT='||count(*)||';SYSDATE='||sysdate from dual;" | sqlplus -s / )

print "The shell variable COUNT is   [$COUNT]"
print "The shell variable SYSDATE is [$SYSDATE]"

exit 0
$ ./x
The shell variable COUNT is   [1]
The shell variable SYSDATE is [27-FEB-2013]
$

dbix::class::storage::dbi::oracle::wherejoins

DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm)	User Contributed Perl Documentation	DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm)

NAME

       DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI).

PURPOSE

       This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.

SYNOPSIS

       DBIx::Class should automagically detect Oracle and use this module with no work from you.

DESCRIPTION

       This class implements Oracle's WhereJoin support.  Instead of:

	   SELECT x FROM y JOIN z ON y.id = z.id

       It will write:

	   SELECT x FROM y, z WHERE y.id = z.id

       It should properly support left joins, and right joins.	Full outer joins are not possible due to the fact that Oracle requires the entire
       query be written to union the results of a left and right join, and by the time this module is called to create the where query and table
       definition part of the SQL query, it's already too late.

METHODS

       See DBIx::Class::SQLMaker::OracleJoins for implementation details.

BUGS

       Does not support full outer joins.  Probably lots more.
