Question

If the SET clause of the UPDATE command is omitted, then all rows in the table will be updated with the new data value ______

a) Partial update
b) Conditional update
c) Full update
d) No update

Answer 1

If the SET clause of the UPDATE command is omitted, no changes will be made to the data in the table, resulting in 'd) No update.' The SET clause is essential for specifying which columns and values to modify in an SQL statement.

Step-by-step explanation:

If the SET clause of the UPDATE command is omitted in SQL, the result would be d) No update. The SET clause specifies the columns that should be modified and the values they should be given. Without the SET clause, the UPDATE statement doesn't have the necessary information to change the data in the table, so no changes will be made. Therefore, omitting the SET clause would not result in a full update, conditional update, or partial update; instead, there would be no action taken on the data within the table at all.
