Data "for" Loop Problem

Hello Everyone,

I'm having a wee bit of a problem. I would like to pass a DB2 query to a variable and then using that variable to perform a 'For' loop.

For example....
Code:
tempfile1=`db2 -x "select cast(OBJECT_ID as integer) from $temp_table where SEQUENCE_NO = $sequence_no"` 

for id in ${tempfile1}
do  

statename=`db2 -x "select STATE_NAME from $temp_table where object_id = $id"`
domain_name=`db2 -x "select domain_name from $temp_table where object_id = $id"`

echo "ID = [$id]"
echo "State = [$statename]"
echo "Domain = [$domain_name]"

done

The problem is when I run this if there are multiple object_id's with the same value but not the same state_name then when it's passed through an echo it looks like this....

Code:
ID = [5132]
State = [State1 State2]
Domain = [Domain1 Domain2]
ID = [5146]
State = [State1]
Domain = [Domain1]
ID = [5156]
State = [State1 State2]
Domain = [Domain1 Domain2]
ID = [5132]
State = [State1 State2]
Domain = [Domain1 Domain2]
ID = [5156]
State = [State1 State2]
Domain = [Domain1 Domain2]

However I would like it to look like this...
Code:
ID = [5132]
State = [State1]
Domain = [Domain1]
ID = [5146]
State = [State1]
Domain = [Domain1]
ID = [5156]
State = [State1]
Domain = [Domain1]
ID = [5132]
State = [State2]
Domain = [Domain2]
ID = [5156]
State = [State2]
Domain = [Domain2]

Would someone be able to see what I'm doing wrong.

Thanks in advance.....

NAME
Excel::Template::Container::Loop - Excel::Template::Container::Loop PURPOSE
To provide looping NODE NAME
LOOP INHERITANCE
Excel::Template::Container ATTRIBUTES
o NAME This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each iteration. CHILDREN
None EFFECTS
None DEPENDENCIES
None USAGE
<loop name="LOOPY"> ... Children here ... </loop> In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array would expose a different hash of parameters to the children. These loops work just like HTML::Template's loops. (I promise I'll give more info here!) There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly acceptable. You can also hide outside variables with inner values, if you desire, just like Perl. AUTHOR
