In an SQL UPDATE statement, what does the SET keyword represent?

  1. The condition to identify records

  2. The new values to be assigned

  3. The table from which to delete records

  4. The fields to be retrieved

The correct answer is: The new values to be assigned

The SET keyword in an SQL UPDATE statement is used to specify the new values that should be assigned to the fields in the records that meet the criteria defined in the WHERE clause. Essentially, it allows you to define what changes you want to make to the existing data in the specified columns of the selected records. This is crucial for updating information to reflect new data accurately. The other options do not accurately represent the function of the SET keyword. Identifying records is typically done with the WHERE clause, while deleting records involves different SQL commands. Retrieving fields is associated with SELECT statements rather than UPDATE operations.
