PI JDBC sender Adapter

i have wroten one join query which is picking a lot of records

and after picking it is updating WSTAT field 2

so every time

pi is picking new record which have value 1

now issue is that

once PI is picking bulk data

for example 100 records at one time

if there is any one record fails in mapping all data is stucked in PI

so i need to process 1 record at a time.

How to achieve it.

Regards

Mohit
