如何使用SQL查询加载第n个到第n个记录？

像

这样的东西

select 10 to 20 columnname from tbl order by columnname

Answer 1

SQL Server 2012有一项名为OFFSET和FETCH的新功能：

SELECT (list of columns)
FROM YourTable
ORDER BY columnName
  OFFSET 10 ROWS 
  FETCH NEXT 10 ROWS ONLY

在2012年之前的版本中，最好的方法是使用带有ROW_NUMBER()函数的CTE（公用表表达式），并使用行号从该CTE中选择 - see more details here

Answer 2

对于SQL 2005及更高版本，您可以使用ROW_NUMBER()

 DECLARE @p0 Int = 10
 DECLARE @p1 Int = 10

 SELECT [t1].[pkCompanyID]
 FROM (
     SELECT ROW_NUMBER() OVER (ORDER BY [t0].[pkCompanyID]) AS [ROW_NUMBER], [t0].[pkCompanyID]
     FROM [tblCompany] AS [t0]
     ) AS [t1]
 WHERE [t1].[ROW_NUMBER] BETWEEN @p0 + 1 AND @p0 + @p1
 ORDER BY [t1].[ROW_NUMBER]
