Update Table from Data set

Question

Hi, Good morining every one.

I am able to insert a record but not able to update it.

I have to update the records in TANLUSR_DUP based on  USR_ID which is the P.Key in this table.

How do I write a code for the following function.

Update table TANLUSR_DUP where Data set. user_id = TANLUSR_DUP.USR_ID

Please find the code I am using.

Any help is appreciated.
