  • 第4题：

    The BOOKINGS table contains online booking information. When a booking is confirmed, the details are transferred to an archival table BOOKINGS_HIST and deleted from the BOOKINGS table. There is no fixed time interval between each online booking and its confirmation. Because sufficient space is not always available from the delete operations the high-water mark (HWM) is moved up and many rows are inserted below the HWM of the table. The BOOKINGS table has Automatic Segment Space Management (ASSM) and row movement enabled. The table is accessible in 24x7 mode. What is the most efficient method to reclaim the space released by the delete operations in the BOOKINGS table？（）

    • A、Perform EXPORT, DROP, and IMPORT operations on the BOOKINGS table sequentially
    • B、Shrink the BOOKINGS table by using the ALTER TABLE SHRINK SPACE command
    • C、Move the BOOKINGS table to a different location by using the ALTER TABLE MOVE command
