F. ALTER DATABASE [ProdDB] SET READ_COMMITTED_SNAPSHOT ON
G. Use (SNAPSHOT] hints in the report queries
H. Use (SNAPSHOT] hints in the update statements
Answer: D,F,G
Explanation:
*Scenario:
The SalesOrderDetail table holds the details about each sale. It is in the Sales schema
owned by the SalesStaff Windows group.
This table is constantly being updated, inserted into, and read.
*Regardless of which office runs a sales force report, the SalesOrderDetail table should only return
valid, committed order data; any orders not yet committed should be ignored.
*READ_COMMITTED_SNAPSHOT { ON | OFF } ON Enables Read-Committed Snapshot option at the
database level. When it is enabled, DML statements start generating row versions even when no
transaction uses Snapshot Isolation. Once this option is enabled, the transactions specifying the read
committed isolation level use row versioning instead of locking. When a transaction runs at the read
committed isolation level, all statements see a snapshot of data as it exists at the start of the
statement. OFF Turns off Read-Committed Snapshot option at the database level. Transactions
specifying the READ COMMITTED isolation level use locking. ALTER DATABASE SET Options (Transact-
SQL) SET Statements (Transact-SQL)
