Code example of SQLserver stored procedure paging query

The content of this article is about the code example of SQL server stored procedure paging query. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Use stored procedures to implement paging queries. The SQL statement is as follows:

USE [DatebaseName]  --数据库名
GO
/****** Object:  StoredProcedure [dbo].[Pagination]    Script Date: 03/30/2019 10:36:52 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

Create PROCEDURE [dbo].[Pagination]
(
    @SqlTable varchar(1000),--要查询的表或视图,也可以一句sql语句
    @SqlPK varchar(50),--主键
    @SqlField varchar(1000),--查询的字段
    @SqlWhere varchar(1000)='', --查询条件 
    @SqlOrder varchar(200),--排序
    @PageSize int=20,--每页的记录数
    @PageIndex int=1, --第几页,默认第一页
    @IsCount bit, --是否获取记录数
    @RecordCount int=0 output
)
AS
SET NOCOUNT ON
DECLARE @PageLowerBound int
DECLARE @PageUpperBound int
DECLARE @sqlstr nvarchar(2000)

--获取记录数
IF @IsCount=1
BEGIN
    SET @sqlstr=N'select @sCount=count(1) FROM '+@SqlTable+' WHERE 1=1 '+@SqlWhere
    Exec sp_executesql @sqlstr,N'@sCount int outPut',@RecordCount OUTPUT
END

SET @PageLowerBound=(@PageIndex-1)*@PageSize
SET @PageUpperBound=@PageLowerBound+@PageSize
CREATE TABLE #pageindex(id int identity(1,1) not null,nid varchar(100))
SET rowcount @PageUpperBound 
SET @sqlstr=N'insert into #pageindex(nid) select '+@SqlPK+' from '+@SqlTable+' where 1=1 '+@SqlWhere+' '+@SqlOrder

Exec sp_executesql @sqlstr
SET @sqlstr=&#39;select &#39;+@SqlField+&#39; FROM &#39;+ @SqlTable +&#39; inner join #pageindex p on &#39;+@SqlPK+&#39;=p.nid and (p.id>&#39;+STR(@PageLowerBound)+&#39;) and (p.id<=&#39;+STR(@PageUpperBound)+&#39;)&#39; +&#39; &#39;+@SqlOrder

Exec sp_executesql @sqlstr
SET NOCOUNT OFF
DROP TABLE #pageindex

But if you have some strange needs, such as not returning to the first page after deleting the current page data, then Continue to request the next page. At this time, there will be a query where the data has been skipped.

The solution is as follows:

USE [DatebaseName]
GO

/****** Object:  StoredProcedure [dbo].[Pagination]    Script Date: 03/30/2019 14:41:39 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE PROCEDURE [dbo].[PaginationSkip]
(
    @SqlTable varchar(1000),--要查询的表或视图,也可以一句sql语句
    @SqlPK varchar(50),--主键
    @SqlField varchar(1000),--查询的字段
    @SqlWhere varchar(1000)='', --查询条件 
    @SqlOrder varchar(200),--排序
    @PageSize int=20,--每页的记录数
    @PageIndex int=1, --第几页,默认第一页
    @IsCount bit, --是否获取记录数
    @RecordCount int=0 output,
    @Skip int=0 --跳过记录数
)
AS
SET NOCOUNT ON
DECLARE @PageLowerBound int
DECLARE @PageUpperBound int
DECLARE @sqlstr nvarchar(2000)

--获取记录数
IF @IsCount=1
BEGIN
    SET @sqlstr=N'select @sCount=count(1) FROM '+@SqlTable+' WHERE 1=1 '+@SqlWhere
    Exec sp_executesql @sqlstr,N'@sCount int outPut',@RecordCount OUTPUT
END

SET @PageLowerBound=(@PageIndex-1)*@PageSize-@Skip  --减去删除的条数,以适应需求
SET @PageUpperBound=@PageLowerBound+@PageSize-@Skip 
CREATE TABLE #pageindex(id int identity(1,1) not null,nid varchar(100))
SET rowcount @PageUpperBound 
SET @sqlstr=N'insert into #pageindex(nid) select '+@SqlPK+' from '+@SqlTable+' where 1=1 '+@SqlWhere+' '+@SqlOrder

Exec sp_executesql @sqlstr
SET @sqlstr=&#39;select &#39;+@SqlField+&#39; FROM &#39;+ @SqlTable +&#39; inner join #pageindex p on &#39;+@SqlPK+&#39;=p.nid and (p.id>&#39;+STR(@PageLowerBound)+&#39;) and (p.id<=&#39;+STR(@PageUpperBound)+&#39;)&#39; +&#39; &#39;+@SqlOrder

Exec sp_executesql @sqlstr
SET NOCOUNT OFF
DROP TABLE #pageindex
GO

Added a Skip parameter to indicate how much to advance. pieces of data, this parameter is the number of pieces you deleted before requesting
