Sender JDBC adapter

Question

Hi All,
I have 2 tables. First table
Header
Name    EmpId  Status
Jai     5601    0
Karthik 5579    0
Item
Name     Contactnumber
Jai      9894268913
Jai      04312432431
Karthik  98984110335
Karthik  04222643993
Now I need to select a single record from Header and all its corresponding records from Item then I need to update the status field to prevent processing the same record and move to next header and all its corresponding Item records. How can I achieve this in a scenario with out BPM? How should I write my SQL and Update SQL in sender commn channel?
Appreciate your help in this.
Thanks & Regards,
Jai Shankar.

Hi Jai,
I guess I got it.
You have to select a single document from the database. The problem is to qualify your select statement.
a) The solution is to select the MIN record (MIN means you select only ONE)!
b) On the other hand you want wo select corresponding from a second table.
So you have to combine a) with b)
a) select * from table_1 where event_id = (select min(event_id) from table_1 where status = 0)
b) select * from table_2 t1, table_1 t2 where t1.name = t2.name
Unfortunately I am not a SQL specialist.
Somebody else should be able to combine the statements a) and b)
