从用户选择top（@count）* 
 

如果 @count 是常数，可以删除括号：

 从用户中选择top 42 * 
 

（后者适用于SQL Server 2000，而前者至少需要2005年）

Is there any way to select, for example, first 10 rows of a table in T-SQL (working MSSQL)?
I think I saw something in Oracle defined as rownum meta variable, used in a following way

select * from Users where rownum<=10

But what about MSSQL?

select top(@count) * from users

If @count is a constant, you can drop the parentheses:

select top 42 * from users

(the latter works on SQL Server 2000 too, while the former requires at least 2005)
