两个分页存储过程
1、分页存储过程
Create PROCEDURE [dbo].[PageRead]
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = '*', -- 需要返回的列
@fldName varchar(255)='',--主键
@ascName varchar(255)='', -- 排序的字段名
@PageSize int , -- 页尺寸
@PageIndex int, -- 页码
@doCount bit , -- 返回记录总数, 非 0 值则返回
@OrderType bit , -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = '''' -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400)
declare @strOrder1 varchar(400) -- 排序类型
if @doCount != 0
begin
if @strWhere !=''''
set @strSQL = 'select count(*) as Total from [' + @tblName + '] where '+@strWhere
else
set @strSQL = 'select count(*) as Total from [' + @tblName + ']'
end
--以上代码的意思是如果@doCount传递过来的不是0,就执行总数统计。以下的所有代码都是@doCount为0的情况
else
begin
if @OrderType != 0
begin
set @strTmp = '<(select min'
set @strOrder = ' order by [' + @fldName +'] desc'
set @strOrder1 = ' order by [' + @ascName +'] desc'
--如果@OrderType不是0,就执行降序,这句很重要!
end
else
begin
set @strTmp = '>(select max'
set @strOrder = ' order by [' + @fldName +'] asc'
set @strOrder1 = ' order by [' + @ascName +'] asc'
end
if @PageIndex = 1
begin
if @strWhere != ''''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from [' + @tblName + '] where ' + @strWhere + ' ' + @strOrder
else
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['+ @tblName + '] '+ @strOrder
--如果是第一页就执行以上代码,这样会加快执行速度
end
else
begin--以下代码赋予了@strSQL以真正执行的SQL代码
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['+ @tblName + '] where [' + @fldName + ']' + @strTmp + '(['+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['+ @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)'+ @strOrder1
if @strWhere !=''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from [' + @tblName + '] where [' + @fldName + ']' + @strTmp + '([' + @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' [' + @fldName + '] from [' + @tblName + '] where ' + @strWhere + ' ' + @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder1
end
if @strWhere !='' --得到记录的总行数
set @strSQL =@strSQL+ '; select count(*) as Total from [' + @tblName + '] where '+ @strWhere
else
set @strSQL =@strSQL+ '; select count(*) as Total from [' + @tblName + ']'
end
exec (@strSQL)
2、分页存储过程
Create PROCEDURE [dbo].[newpPageSel](@start int,@pageSize int)
AS
BEGIN
declare @sql nvarchar(max)
set @sql='select top '+str(@pageSize)+' username,name,erpBook,hrs,newpro,fixed,sales,skperm,financial,supply '+
'from dbo.tblpermission where username not in ('+
'select top '+str(@start)+' username from dbo.tblpermission order by username)'+
' order by username'
execute(@sql) --因select top后不支技直接接参数,所以写成了字符串@sql
--select @sql
END
