資料庫 '%1' 無法使用快照集隔離或 READ COMMITTED 快照集，因為 SQL Server 啟動時，使用了一或多個未記載的追蹤旗標，所以防止針對版本控制啟用資料庫。以快照集隔離啟動的交易會失敗，在 READ COMMITTED 快照集下執行的查詢會成功，但會回到以鎖定為基礎的 READ COMMITTED。

Snapshot isolation or read committed snapshot is not available in database '%1' because SQL Server was started with one or more undocumented trace flags that prevent enabling database for versioning. Transaction started with snapshot isolation will fail and a query running under read committed snapshot will succeed but will resort back to lock based read committed.
