SQL Server 中的行偏移量
SQL Server 中是否有任何方法可以从给定偏移量开始获取结果?例如,在另一种类型的 SQL 数据库中,可以这样做:
Is there any way in SQL Server to get the results starting at a given offset? For example, in another type of SQL database, it's possible to do:
SELECT * FROM MyTable OFFSET 50 LIMIT 25
获得结果 51-75.SQL Server 中似乎不存在此构造.
to get results 51-75. This construct does not appear to exist in SQL Server.
如何在不加载所有我不关心的行的情况下完成此操作?谢谢!
How can I accomplish this without loading all the rows I don't care about? Thanks!
推荐答案
我会避免使用 SELECT *
.指定您实际需要的列,即使它可能是所有列.
I would avoid using SELECT *
. Specify columns you actually want even though it may be all of them.
