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.....

Case 5132 gets returned twice by your first select because it's in two rows.

Then in the state select, two states get returned because there are two states associated with 5132.

I suggest doing something like....

Code:
db2 -x ..... | while read A B C D
do
....
done
