Updating field from one table to another sql

None of these two features will help us here, though.

On the right-hand side, scroll down to get to the box that says, “Safe Updates”. If you omit the WHERE clause, all records in the table will be updated! The WHERE clause specifies which record(s) that should be updated.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.
