Had we used a non-existent condition in the WHERE clause (for instance, an employee number of 999909), My SQL would have allowed the execution of the query, given that the SQL syntax is correct.Through the ticking of this option, the software could prevent you from losing significant amounts of data or some of the changes you made earlier.However, it could also eliminate the possibility of the state of the data in our database.Now, we are ready to dive into the UPDATE statement. By using this code structure, SQL will change the record or records satisfying the WHERE condition, updating the old values of the columns listed with the new ones.We can see that employee number 999901 is John Smith.
