The sqlplus (part of the oracle distribution) command returns 3 lines, the capitalised field names , a separator line and the values.
Code:
$(echo $(sqlplus -s /nolog <<EOQ
connect ${USER}/${PASS}@${SID}
set linesize 1000
select
  file_id, 
  file_desc, 
  file_freq_cd, 
  load_table_nm, 
  load_stored_procd_nm, 
  load_proc_typ_nm, 
  err_rec_cnt_thrsld_nbr, 
  file_expc_rec_cnt 
From Table1 
where file_id=1 ;
quit
EOQ )
| grep -v '-----'|awk 'if(/^FILE_ID/){print "names=("$0")"}else{print "values=("$0")";})
index=0
for i in ${names[@]} ; do
  export $i=${values[$index]}
  index=$(($index + 1 ))
done

So the next step is to read the field names and values into 2 arrays and then step through the arrays assigning and exporting the values

I use grep to remove the unwanted separator line, then use awk to write out my array assignment statements, these are evaluated by the $(...) expansion.

Then we simply step through the 2 arrays...

apache::session::oracle

Apache::Session::Oracle(3pm)				User Contributed Perl Documentation			      Apache::Session::Oracle(3pm)

NAME

       Apache::Session::Oracle - An implementation of Apache::Session

SYNOPSIS

	use Apache::Session::Oracle;

	#if you want Apache::Session to open new DB handles:

	tie %hash, 'Apache::Session::Oracle', $id, {
	   DataSource => 'dbi:Oracle:sessions',
	   UserName   => $db_user,
	   Password   => $db_pass,
	   Commit     => 1
	};

	#or, if your handles are already opened:

	tie %hash, 'Apache::Session::Oracle', $id, {
	   Handle => $dbh,
	   Commit => 1
	};

DESCRIPTION

       This module is an implementation of Apache::Session.  It uses the Oracle backing store and no locking.  See the example, and the
       documentation for Apache::Session::Store::Oracle for more details.

USAGE

       The special Apache::Session argument for this module is Commit.	You MUST provide the Commit argument, which instructs this module to
       either commit the transaction when it is finished, or to simply do nothing.  This feature is provided so that this module will not have
       adverse interactions with your local transaction policy, nor your local database handle caching policy.	The argument is mandatory in order
       to make you think about this problem.

       This module also respects the LongReadLen argument, which specifies the maximum size of the session object.  If not specified, the default
       maximum is 8 KB.

AUTHOR

       This module was written by Jeffrey William Baker <jwbaker@acm.org>.
