How to update the field status in RUN time

Hi,

In my JDBC to file scenario when ever the JDBC channel picking the data of TXN_D field I want to update the STATUS field to 'Y' in oracle DB.

EX: I have 1 table XXX

      FIELDS:  TXN_ID         ,STATUS
          Data       10                       N

                         20                      N

                         30                      N

                         40                      N

When ever my JDBC sender channel picking the data of TXN_ID field then STATUS filed data had to be update to Y. Plese help me on this.
