That is not going to work either.  That is actually what it is doing
now, the sql error out the open and the execution continue on to do the
fetch statement.  The fetch is using the parent cursor and getting the
result of the parent select statement.

Looks like, I'm going to need to use the good old RPG.

OK....one other possibility...

Open the cursor on the first call only...then have a separate procedure
close the cursor at termination time....

Subject: RE: Is SQL cursor open at the job level?

I can't close the cursor, the parent thread still needs it.  See below
for detail on what I'm doing:

This is what I try to achieve:
Example: 
1) MYFILE has 2 fields: CHILD and PARENT.  
2) If the data looks like below
CHILD           PARENT
AAA             BBB
CCC             AAA
DDD             BBB
EEE             JJJ
3) This procedure basically need to return all family member back to the
caller.  If say the caller pass DDD, this procedure should return:
DDDBBBAAACCC

Below is what I got (Not able to test it because when it recursive calls
the getFamilyMember, it gets the cursor already open error and the
return result become incorrect:

D getFamilyMember...                                          
D                 pr            90    varying

Is this a SQL Procedure or RPG Procedure using SQL?

If RPG, add the HSPEC
