You are the administrator of a SQL Server 2000 computer. The server contains a database named Sales. You perform full database backups every two days. You also run regular database consistency checks on the server. The most recent check of the Sales database returns the following message.
“CHECKDB found 0 allocation errors and 9 consistency errors in the table ’Orders’ (object ID 214575782).”
You want to correct the data integrity errors while minimizing the amount of data lost. What should you do?
选项
A、Disconnect users from the Sales database.
Enable the single user database option.
Execute the DBCC CHECKTABLE statement for the Orders table, and specify the
REPAIR_REBUILD option.
B、Disconnect users from the Sales database.
Enable the DBO use only database option.
Execute the DBCC CHECKTABLE statement for the Orders table, and specify the
REPAIR_REBUILD option.
C、Disconnect users from the Sales database.
Execute the RESTORE DATABASE statement for the Sales database
D、Execute the DBCC CLEANTABLE statement for the Orders table.
E、Execute the sp_table_validation stored procedure for the Orders table.
答案
A
解析
Explanation: We should repair the database with the DBCC CHECKTABLE REPAIR_REBUILD command. We should run this repair statement when the database is configured to single user.
Note: DBCC CHECKTABLE checks the integrity of the data, index, text, ntext, and image pages for the specified table or indexed view. DBCC CHECKTABLE can take a specified repair option to repair the found errors but must be in single-user mode to use a repair option.
It can specify the REBUILD_FAST option, which performs minor, non time-consuming repair actions such as repairing extra keys in nonclustered indexes and can be done quickly and without risk of data loss; and it can also specify the REPAIR_REBUILD option, which performs all repairs that can done by REPAIR_FAST and as well as time-consuming repairs such as index rebuilding. These repairs can also be done without risk of data loss.
Incorrect Answers:
B: The database option DBO use only, would only allow the database owner running the database. This might be too restrictive.
C: We are not told when how often consistency checks are performed but assuming that consistency occurs more frequently than the database backups then using RESTORE DATABASE to restore a database from the last full backup would result in the loss of data entered into the database since the last full database backup was performed. This would result in data loss.
D: DBCC CLEANTABLE is used to reclaim space after a variable length column or a text column is dropped using the ALTER TABLE DROP COLUMN statement.
E: The sp_table_validation stored procedure returns rowcount or checksum information on a table or indexed view, or compares the provided rowcount or checksum information with the specified table or indexed view. This stored procedure is used in replication and checks that the structure of the table being replicated between two tables are identical, i.e., that the tables have the same columns existing in the same order, same data types and lengths, and same NULL/NOT NULL conditions.
