Question

If the WHERE clause is omitted from the UPDATE command, then all columns in the table will be changed.

a) True
b) False

Answer 1

If the WHERE clause is omitted from the UPDATE command, all rows in the table will be affected, but not all columns will be changed. The columns that will be updated depend on the SET clause specified in the UPDATE command.

Step-by-step explanation:

The statement is False. If the WHERE clause is omitted from the UPDATE command, all rows in the table will be affected, but not all columns will be changed. The columns that will be updated depend on the SET clause specified in the UPDATE command. For example, if the SET clause specifies to update only the 'name' column, then only the 'name' column will be changed for all rows in the table.
