Question

If the ____ clause of the UPDATE command is omitted, then all the rows in the specified table will be changed.​

a. WHERE
b. SET
c. FROM
d. INTO

Answer 1

The correct answer is a. WHERE clause. Without the WHERE clause in an UPDATE command, all rows in the table will be affected. The WHERE clause is used to specify which rows to update.

Step-by-step explanation:

If the WHERE clause of the UPDATE command is omitted, then all the rows in the specified table will be changed. The correct answer is a. WHERE.

The UPDATE command in SQL is used to modify existing records in a table. The SET clause indicates which columns to modify and the values they should be given. If you do not specify a WHERE clause, the UPDATE command will apply to all records in the table. Therefore, to restrict the update to specific rows, the WHERE clause needs to be used to filter out the records that should not be affected by the update.
