declare @TopCount int
set @TopCount = 100
select top (@TopCount) * from AdventureWorks.HumanResources.Employee

如果有Like等字句,一定要拼Sql的话,也应该使用sp_executesql来执行,示例如下:

declare @TopCount int --定义top 数量
set @TopCount = 100
declare @Title nvarchar(100) --定义like内容
set @Title = '%n%'
declare @SelectSql nvarchar(max)
set @SelectSql = '
select top (@TopCountPar) *
from AdventureWorks.HumanResources.Employee
where Title like @TitlePar' --使用参数化的top和like

--使用sp_executesql 来执行,可以提高效率
exec sp_executesql @SelectSql,
[email protected] as int,@TitlePar as nvarchar(100)',
@TopCountPar = @TopCount,@TitlePar = @Title
