UPDATE Client_detail, Release_detail SET Client_detail.Client = "Airtel-India", Release_detail.Client = "Airtel-India"
WHERE (((Client_detail.Client)="Bharati Chennai") AND ((Release_detail.Client)="Bharati Chennai"));

but after running an error message is shown like

Microsoft access didnt update 0 fileds due to a type conversion failure,16 records due to key violations,0 records due to validation rule violations

Hi Adil!

I think the main problem would be that you are going to update multiple records, field "client" to the same value. Fiel "client" is a Primary key so it must not be the same, as it has to be unique.

Adil!

Actually I have realized that I am missing the join between those two tables. If you do not join them the query result affect all combinations of all records from both tables matching your criteria.
I suppose you should try to join the tables via the Primary key fields ("client").
