分享一个通用的分页SQL

复制代码
代码如下:————————————
–用途:分页存储过程(对有主键的表效率极高) –说明:
———————————— ALTER PROCEDURE
[UP_GetRecordByPage] @tblName varchar(255), — 表名 @fldName
varchar(255), — 主键字段名 @PageSize int = 10, — 页尺寸 @PageIndex int
= 1, — 页码 @IsReCount bit = 0, — 返回记录总数, 非0 值则返回
@OrderType bit = 0, — 设置排序类型, 非0 值则降序 @strWhere
varchar(1000) = ” — 查询条件(注意: 不要加where) AS declare @strSQL
varchar(6000) — 主语句 declare @strTmp varchar(100) — 临时变量 declare
@strOrder varchar(400) — 排序类型 if @OrderType != 0 begin set @strTmp
= ‘(select min’ set @strOrder = ‘ order by [‘ + @fldName +’] desc’ end
else begin set @strTmp = ‘(select max’ set @strOrder = ‘ order by [‘ +
@fldName +’] asc’ end set @strSQL = ‘select top ‘ + str(@PageSize) + ‘
* from [‘ + @tblName + ‘] where [‘ + @fldName + ‘]’ + @strTmp +
‘([‘ + @fldName + ‘]) from (select top ‘ +
str((@PageIndex-1)*@PageSize) + ‘ [‘ + @fldName + ‘] from [‘ +
@tblName + ‘]’ + @strOrder + ‘) as tblTmp)’ + @strOrder if @strWhere !=
” set @strSQL = ‘select top ‘ + str(@PageSize) + ‘ * from [‘ +
@tblName + ‘] where [‘ + @fldName + ‘]’ + @strTmp + ‘([‘ + @fldName

又很久没写博客,今天记录一个SQLserver通用分页存储过程(适用于SqlServer2000及以上版本)

复制代码 代码如下: CREATE PROCEDURE page
@tblName varchar(255), — 表名 @strGetFields varchar(1000) = ‘*’, —
需要返回的列 @fldName varchar(255)=’id’, — 排序的字段名 @PageSize int =
10, — 页尺寸 @PageIndex int = 1, — 页码 @doCount bit = 0, —
返回记录总数, 非 0 值则返回 @OrderType bit = 0, — 设置排序类型, 非 0
值则降序 0:asc 1:desc @strWhere varchar(1500) = ”, — 查询条件 (注意:
不要加 where) @ID nvarchar(50)=’id’ –主表的列。。最好是主键 AS declare
@strSQL varchar(5000) — 主语句 declare @strTmp varchar(110) — 临时变量
declare @strOrder varchar(400) — 排序类 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’
–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’
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 + ‘( ‘+ @ID + ‘ ) from (select top ‘ +
str((@PageIndex-1)*@PageSize) + ‘ ‘+ @fldName + ‘ from ‘ + @tblName +
@strOrder + ‘) as tblTmp)’+ @strOrder if @strWhere != ” set @strSQL =
‘select top ‘ + str(@PageSize) +’ ‘+@strGetFields+ ‘ from ‘ + @tblName +
‘ where ‘ + @fldName + ‘ ‘ + @strTmp + ‘(‘ + @ID + ‘) from (select top ‘

  • ‘]) from (select top ‘ + str((@PageIndex-1)*@PageSize) + ‘ [‘ +
    @fldName + ‘] from [‘ + @tblName + ‘] where ‘ + @strWhere + ‘ ‘ +
    @strOrder + ‘) as tblTmp) and ‘ + @strWhere + ‘ ‘ + @strOrder if
    @PageIndex = 1 begin set @strTmp =” if @strWhere != ” set @strTmp = ‘
    where ‘ + @strWhere set @strSQL = ‘select top ‘ + str(@PageSize) + ‘ *
    from [‘ + @tblName + ‘]’ + @strTmp + ‘ ‘ + @strOrder end if @IsReCount
    != 0 set @strSQL = ‘select count(*) as Total from [‘ + @tblName +
    ‘]’+’ where ‘ + @strWhere exec (@strSQL)

1.支持连表

  • str((@PageIndex-1)*@PageSize) + ‘ ‘ + @fldName + ‘ from ‘ + @tblName
  • ‘ where ‘ + @strWhere + ‘ ‘ + @strOrder + ‘) as tblTmp) and ‘ +
    @strWhere + ‘ ‘ + @strOrder end end exec (@strSQL)

2.支持条件查询
