CYQ.Data 数据框架 SQL2005 分页存储过程

Principles | | | pubdate :2011/5/18 1:56:38#TopicOwner  

下面是CYQ.Data 数据框架在SQL2005的分页存储过程的代码：

Create procedure [SelectBase]
@PageIndex         int,
@PageSize      int,
@TableName    nvarchar(4000),
@Where     nvarchar(max)=''
as
Declare @rowcount    int
Declare @intStart    int
Declare @intEnd         int
Declare @SQl nvarchar(max), @WhereR nvarchar(max), @OrderBy nvarchar(max)
set @rowcount=0
set nocount on
if @Where<>''
begin
set @Where=' and '+@Where
end
if CHARINDEX('order by', @Where)>0
begin
set @WhereR=substring(@Where, 1, CHARINDEX('order by',@Where)-1) --取得条件
set @OrderBy=substring(@Where, CHARINDEX('order by',@Where), Len(@Where)) --取得排序方式(order by 字段 方式)
end
else
begin
set @WhereR=@Where
set @OrderBy=' order by id asc'
end
set @SQl='SELECT @rowcount=count(*) from '+cast(@TableName as varchar(4000))+' where 1=1 '+@WhereR
exec sp_executeSql @SQl,N'@rowcount int output',@rowcount output
if @PageIndex=0 and @PageSize=0 --不进行分页,查询所有数据列表
begin
set @SQl='SELECT * from '+cast(@TableName as varchar(4000))+' where 1=1 '+@Where
end
else --进行分页查询数据列表
begin
set @intStart=(@PageIndex-1)*@PageSize+1;
set @intEnd=@intStart+@PageSize-1
set @SQl='select * from(select *,ROW_NUMBER() OVER('+cast(@OrderBy as nvarchar(400))+') as row from '
set @SQl=@SQL+@TableName+' where 1=1 '+@WhereR+') as a where row between '+cast(@intStart as varchar)+' and '+cast(@intEnd as varchar)
end
exec sp_executeSql @SQl
return @rowcount
set nocount off
