SQLServer实现分页

– exec prcPageResult 1,’*’,‘SysRole’,’’,‘RoleID’,0,‘RoleID’,1

alter PROCEDURE prcPageResult
– 获得某一页的数据 –
@currPage int = 1, --当前页页码 (即Top currPage)
@showColumn varchar(2000) = ‘*’, --需要得到的字段 (即 column1,column2,…)
@tabName varchar(2000), --需要查看的表名 (即 from table_name)
@strCondition varchar(2000) = ‘’, --查询条件 (即 where condition…) 不用加where关键字
@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

AS
BEGIN – 存储过程开始
– 该存储过程需要用到的几个变量 –
DECLARE @strTemp varchar(1000)
DECLARE @strSql varchar(4000) --该存储过程最后执行的语句
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即执行降序
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 – 如果是第一页
BEGIN
IF @strCondition != ‘’
SET @strSql = 'SELECT TOP ‘+STR(@pageSize)+’ ‘+@showColumn+’ FROM '+@tabName+
’ WHERE '+@strCondition+@strOrderType
ELSE
SET @strSql = 'SELECT TOP ‘+STR(@pageSize)+’ ‘+@showColumn+’ FROM '+@tabName+@strOrderType
END

ELSE – 其他页
BEGIN
IF @strCondition !=’’
SET @strSql = ‘SELECT TOP ‘+STR(@pageSize)+’ ‘+@showColumn+’ FROM ‘+@tabName+
’ WHERE ‘+@strCondition+’ AND ‘+@pkColumn+@strTemp+’(’+@pkColumn+’)’+’ FROM (SELECT TOP ‘+STR((@currPage-1)@pageSize)+
’ ‘+@pkColumn+’ FROM ‘+@tabName+@strOrderType+’) AS TabTemp)’+@strOrderType
ELSE
SET @strSql = ‘SELECT TOP ‘+STR(@pageSize)+’ ‘+@showColumn+’ FROM ‘+@tabName+
’ WHERE ‘+@pkColumn+@strTemp+’(’+@pkColumn+’)’+’ FROM (SELECT TOP '+STR((@currPage-1)@pageSize)+’ ‘+@pkColumn+
’ FROM ‘+@tabName+@strOrderType+’) AS TabTemp)’+@strOrderType
END

END
EXEC (@strSql)
END – 存储过程结束
