SQL Server自己收集比较强大的分页存储过程 推荐

感兴趣的小伙伴，下面一起跟随脚本之家 jb51.cc的小编两巴掌来看看吧！

代码如下:

 
set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 
ALTER PROCEDURE [dbo].[proc_page]

@tblName nvarchar(200),----要显示的表或多个表的连接lihu 
@fldName nvarchar(500) = '*',----要显示的字段列表 
@pageSize int = 10,----每页显示的记录个数 
@page int = 1,----要显示那一页的记录 
@fldSort nvarchar(200) = null,----排序字段列表或条件 
@Sort bit = 0,----排序方法，0为升序，1为降序(如果是多字段排列Sort指代最后一个排序字段的排列顺序(最后一个排序字段不加排序标记)--程序传参如：' SortA Asc,SortB Desc,SortC ') 
@strCondition nvarchar(1000),----查询条件,不需where 
@ID nvarchar(150),----主表的主键 
@Dist bit = 0,----是否添加查询字段的 DISTINCT 默认0不添加/1添加 
@pageCount int = 1 output,----查询结果分页后的总页数 
@Counts int = 1 output ----查询到的记录数 
)
