How to update the restricted rows that were selcted using fetch

Question

Hi
I have to fetch  one row at a time from my staging table using JDBC Sender Adapter,  which is configured against AS400 DB2 and push it to R/3.
The select  SQL looks like this in JDBC Sender Adapter
     <b>select  jedata, oxruns from fxjrnep2 where oxsts=' '   fetch first 1 rows only</b>
                                   and
update sql is
     <b>update suplib.FXJRNEP2 set OXSTS='SUC' where OXSTS=' ' </b>
The problem here is my select gets one row, which is what i want, but my update actually updates all the rows that satisfied the where condition oxsts=' ' instead of one.
  I couldn't  use <b>fetch first 1 rows only</b> at the end of the update sql to update the selected row. DB2 does not allow  fetch in update sql.
Can anyone suggest solution here or recommend alternative?
Best Regards
Venkat

Answer 1

check for update query where u can club the select stmt u had used with udpate like:
update suplib.FXJRNEP2 set OXSTS='SUC' where OXSTS = (select jedata, oxruns from fxjrnep2 where oxsts=' ' fetch first 1 rows only
just need to try combinations of this type.
if still this is not working use a bpm and get all the records where OXSTS is null and process record one by one within a block
