OFFSET & FECTH 关键字与ORDER BY结合使用,实现对查询结果的分页

一、单独使用OFFSET:

示例:查询所有职员的信息,按雇佣日期排序并跳过前285条记录(共290条)

1 USE AdventureWorks2014
2 SELECT [BusinessEntityID],[HireDate],[JobTitle]
3 FROM [HumanResources].[Employee]
4 ORDER BY [BusinessEntityID]
5 OFFSET 285 ROWS

查询结果:

BusinessEntityID HireDate JobTitle
1 286    2013-05-30    Sales Representative
2 287    2012-04-16    European Sales Manager
3 288    2013-05-30    Sales Representative
4 289    2012-05-30    Sales Representative
5 290    2012-05-30    Sales Representative

二、OFFSET和FECTH结合使用:

示例:查询所有职员的信息,按雇佣日期排序并跳过前10条记录再显示之后的5条记录

1 USE AdventureWorks2014
2 SELECT [BusinessEntityID],[HireDate],[JobTitle]
3 FROM [HumanResources].[Employee]
4 ORDER BY [BusinessEntityID]
5 OFFSET 10 ROWS
6 FETCH NEXT 5 ROWS ONLY

查询结果:

BusinessEntityID HireDate JobTitle
1 11    2010-12-05    Senior Tool Designer
2 12    2007-12-11    Tool Designer
3 13    2010-12-23    Tool Designer
4 14    2010-12-30    Senior Design Engineer
5 15    2011-01-18    Design Engineer
