我正在尝试执行以下命令以强制更新使用非聚集索引：
- UPDATE Flights
- SET Airtime=5555678
- WHERE Distance=10000
- OPTION (TABLE HINT(Flights,INDEX (DistanceIndex)))
……这是错误的：
Msg 8724,Level 16,State 1,Line 75
Cannot execute query. Table-valued or OPENROWSET function ‘Flights’ cannot be specified in the TABLE HINT clause.
关于如何在TABLE HINT语句中正确形成语法,我找不到任何明确的建议.
请问任何人都可以告诉我哪里出错了？
解决方法
试试以下：
- UPDATE F
- SET F.Airtime=5555678
- FROM Flights F WITH (INDEX (DistanceIndex))
- WHERE F.Distance=10000
要么
- UPDATE Flights
- SET Airtime=5555678
- FROM Flights -- this line is added to your initial query
- WHERE Distance=10000
- OPTION (TABLE HINT(Flights,INDEX (DistanceIndex)))
