2. Query the data of articles 1 to 5 of the collection

Select * from (select ROW_NUMBER () over (order by id asc) as' rowNumber', * from table1) as temp where rowNumber between 1 and 5

Complete Sql statement

Declare @ pagesize int; declare @ pageindex int; set @ pagesize = 3set @ pageindex = 1;-- first page select * from (select ROW_NUMBER () over (order by id asc) as' rowNumber', * from table1) as temp where rowNumber between (@ pageindex-1) * @ pagesize) + 1) and (@ pageindex*@pagesize) set @ pageindex = 2 -second page select * from (select ROW_NUMBER () over (order by id asc) as' rowNumber', * from table1) as temp where rowNumber between (@ pageindex-1) * @ pagesize) + 1) and (@ pageindex*@pagesize) set @ pageindex = 3;-third page select * from (select ROW_NUMBER () over (order by id asc) as' rowNumber', * from table1) as temp where rowNumber between (@ pageindex-1) * @ pagesize) + 1) and (@ pageindex*@pagesize) set @ pageindex = 4 Page 4 select * from (select ROW_NUMBER () over (order by id asc) as' rowNumber', * from table1) as temp where rowNumber between ((@ pageindex-1) * @ pagesize) + 1) and (@ pageindex*@pagesize)

Let's write a stored procedure paging.

Alter Procedure PagePager @ TableName varchar (80), @ File varchar (1000),-- @ Where varchar (1000),-with and connection @ OrderFile varchar (100),-- sort field @ OrderType varchar (10),-- asc: order, desc: reverse @ PageSize varchar (10),-- @ PageIndex varchar (10)-- as if (ISNULL (@ OrderFile,'') ='') begin set @ OrderFile = 'ID' End if (ISNULL (@ OrderType,'') =') begin set @ OrderType = 'asc' end if (ISNULL (@ File,'') ='') begin set @ File ='* 'end declare @ select varchar (8000) set @ select =' select'+ @ File + 'from (select *) ROW_NUMBER () over (order by'+ @ OrderFile +'+ @ OrderType +') as''rowNumber'' from' + @ TableName + 'where 1room1' + @ Where +') temp where rowNumber between (('+ @ PageIndex +'- 1) *'+ @ PageSize+') + 1) and ('+ @ PageIndex +'*'+ @ PageSize+') 'exec (@ select) above is how to use row_number to implement paging in SQL Server shared by the editor.
