Question

I am trying to update the SSN for a customer by searching for them based on the old SSN then updating it. What am I missing? This will not return a result even though i know i have matches for ssNum in the database. Thanks.

String query = "UPDATE Customers SET ss_num = ('" + updateSsn
                + "') WHERE ss_num = ('" + ssNum + "')";

Answer 1

you need to use executeUpdate() method, which doesn’t return ResultSet, but it will return numberOfRowsUpdated

Use PreparedStatement instead
