项目中用到的SQLServer分页查询存储过程。

【存储过程】

create PROCEDURE prcPageResult

-- 获得某一页的数据 --

@currPage int = 1,                         --当前页页码 (即Top currPage)

@showColumn varchar(2000) = '*',           --须要得到的字段 (即 column1,column2,......)

@strCondition varchar(2000) = '',          --查询条件 (即 where condition......) 不用加wherekeyword

@ascColumn varchar(100) = '',              --排序的字段名 (即 order by column asc/desc)

@bitOrderType bit = 0,                     --排序的类型 (0为升序,1为降序)

@pkColumn varchar(50) = '',                --主键名称

@pageSize int = 20,                        --分页大小

@RecordCount int output --返回总行数

AS

BEGIN -- 存储过程開始

-- 该存储过程须要用到的几个变量 --

DECLARE @strTemp varchar(1000)

DECLARE @strSql varchar(4000)                   --该存储过程最后运行的语句

DECLARE @strSql01 varchar(4000) 

DECLARE @strOrderType varchar(1000)      --排序类型语句 (order by column asc或者order by column desc)

BEGIN

IF @bitOrderType = 1   -- bitOrderType=1即运行降序

BEGIN

    SET @strOrderType = ' ORDER BY '+@ascColumn+' DESC'

    SET @strTemp = '<(SELECT min'

END

ELSE

BEGIN

    SET @strOrderType = ' ORDER BY '+@ascColumn+' ASC'

    SET @strTemp = '>(SELECT max'

END

IF @currPage = 1    -- 假设是第一页

BEGIN

    IF @strCondition != ''

        SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@showColumn+' FROM dbo.DemoData '+

            ' WHERE '+@strCondition+@strOrderType

    ELSE

        SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@showColumn+' FROM dbo.DemoData '+@strOrderType

END

ELSE    -- 其它页

BEGIN

    IF @strCondition !=''

        SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@showColumn+' FROM dbo.DemoData '+

        ' WHERE '+@strCondition+' AND '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currPage-1)*@pageSize)+

        ' '+@pkColumn+' FROM dbo.DemoData '+@strOrderType+') AS TabTemp)'+@strOrderType

    ELSE

        SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@showColumn+' FROM dbo.DemoData '+

        ' WHERE '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currPage-1)*@pageSize)+' '+@pkColumn+

        ' FROM dbo.DemoData '+@strOrderType+') AS TabTemp)'+@strOrderType

END

END

select @RecordCount=COUNT(*) from dbo.DemoData

EXEC (@strSql)

END  -- 存储过程结束

GO

【调用方式】

DECLARE @RecordCount int

exec prcPageResult 1,'*','','id',1,'id',10,@RecordCount out

SELECT @RecordCount

---

DECLARE @RecordCount int

exec prcPageResult 1,'*','name=''hugh''','id',0,'id',10,@RecordCount out --存储过程中转义字符为‘。所以name=’hugh'正确的写法应该是'name=''hugh'''而不是'name=/'hugh/''

SELECT @RecordCount
