这是我的分页存储过程，应用过几个项目了，也改过很多次，支持子查询或联表查询。特发出来交流一下，大家请P。

 

 

eg:简单的实例

-->DECLARE    @return_value int,
        @RecordCount int,
        @totalPage int

EXEC    @return_value = [dbo].[p_generalTablePage]
        @strTbName = N'webTable',
        @strFeilds = NULL,
        @strOrder = NULL,
        @strWhere = NULL,
        @PageSize = 20,
        @PageIndex = 1,
        @masterFeilds = N'wid',
        @OrderType = 1,
        @RecordCount = @RecordCount OUTPUT,
        @totalPage = @totalPage OUTPUT

SELECT    @RecordCount as N'@RecordCount',
        @totalPage as N'@totalPage'

SELECT    'Return Value' = @return_value

GO

  

稍稍复杂点

        @strOrder = N'City desc,shortname desc',
        @strWhere = N'siteid=34',
        @PageSize = 20,
        @PageIndex = 1,

        @totalPage = @totalPage OUTPUT

SELECT    @RecordCount as N'@RecordCount',
        @totalPage as N'@totalPage'

DECLARE    @return_value int,
