sql 存储过程分页

首先思想：

利用：
1.
SELECT TOP 页大小 *
FROM TestTable
WHERE (ID >
(SELECT MAX(id)
FROM (SELECT TOP 页大小*页数 id
FROM 表
ORDER BY id) AS T))
ORDER BY ID

需要注意的是如果存在相同记录可能会出错,所以可以将表加入自增队列进行判断即可

2.
：(利用Not In和SELECT TOP分页)
语句形式：

SELECT TOP pagesize *
FROM TestTable
WHERE (ID NOT IN
(SELECT TOP pagesize*page id
FROM 表
ORDER BY id))
ORDER BY ID

很容易理解，然后我们转化为存储过程：
CREATE PROCEDURE hhhb_PageView1
@PageIndex INT, --页面索引,从datagrid中获取
@PageSize INT, --页面显示数量，从datagrid中获取
@RecordCount INT OUT, --返回记录总数
@PageCount INT OUT, --返回分页后页数
@strGetFields nvarchar(1000), -- 需要查询的列 首尾要有空格
@tableName nvarchar(500) , --表名称 首尾要有空格
@ID nvarchar(100), --主键,（为表的主键）
@strWhere nvarchar(1000) ='', -- 查询条件 (注意: 不要加 where)
@sortName nvarchar(50) =' asc ' , --排序方式
@orderName nvarchar(100) --父级查询排序方式

AS
declare @countSelect nvarchar(2000)
--设置统计查询语句
if len(@strWhere) =0
--如果没有查询条件
begin
set @countSelect=N'SELECT @CountRecord = COUNT(*) FROM '+@tableName
end
else
--否则
begin
set @countSelect=N'SELECT @CountRecord = COUNT(*) FROM '+@tableName+' where '+@strWhere
end
--执行并返回总数
exec sp_executesql @countSelect,N'@CountRecord int output',@RecordCount output
SET @PageCount = CEILING(@RecordCount * 1.0 / @PageSize)
SET NOCOUNT ON
DECLARE @SQLSTR NVARCHAR(3000)
--实际总共的页码小于当前页码 或者 最大页码
if @PageCount>=0
--如果分页后页数大于0
begin
if @PageCount<=@PageIndex and @PageCount>0 --如果实际总共的页数小于datagrid索引的页数
--or @PageCount=1
begin
--设置为最后一页
set @PageIndex=@PageCount-1
end
else if @PageCount<=@PageIndex and @PageCount=0
begin
set @PageIndex=0;
end
end
IF @PageIndex = 0 OR @PageCount <= 1 --如果为第一页
begin
if len(@strWhere) =0
begin
SET @SQLSTR =N'SELECT TOP '+STR( @PageSize )+@strGetFields+' FROM '+@tableName+' ORDER BY '+@orderName+@sortName
end
else
begin
SET @SQLSTR =N'SELECT TOP '+STR( @PageSize )+@strGetFields+' FROM '+@tableName+' where '+@strWhere+' ORDER BY '+@orderName+@sortName
end
end
ELSE IF @PageIndex = @PageCount - 1 --如果为最后一页
begin
if len(@strWhere) =0
begin
SET @SQLSTR =N' SELECT '+@strGetFields+' FROM '+@tableName+' where '+@ID+' not in ( SELECT TOP '+STR(/*@RecordCount - */@PageSize * @PageIndex )+@ID+' FROM '+@tableName+'ORDER BY '+@orderName+@sortName+' ) ORDER BY '+@orderName+@sortName

end
end
ELSE --否则执行
begin
if len(@strWhere) =0
begin
SET @SQLSTR =N' SELECT TOP '+STR( @PageSize )+@strGetFields+' FROM '+@tableName+' where '+@ID+' not in ( SELECT TOP '+STR( /*@RecordCount - */@PageSize * @PageIndex )+@ID+' FROM '+@tableName+' ORDER BY '+@orderName+@sortName+' ) ORDER BY '+@orderName+@sortName
end
else

end
EXEC (@SQLSTR)

调用存储过程：
SqlCommand mySqlCommand = new SqlCommand("sp_PageView", acct.dbt.GetSqlConnection());
mySqlCommand.CommandType = CommandType.StoredProcedure;
SqlParameter workParm;

//搜索表字段，以","号分隔
workParm = mySqlCommand.Parameters.Add("@strGetFields", SqlDbType.NVarChar, 1000);

mySqlCommand.Parameters["@strGetFields"].Value = " a.ProId,b.Supplier_Name_Simple,b.Pro_Config, a.SPXZ, a.CDSX, a.GYS,a.XLBM, a.XLMC, a.YWMC," +

"JHJG_Fg_Name = (CASE a.JHJG_Fg WHEN 1 THEN '包含' WHEN 2 THEN '不含' END), " +
"CDSX_Name = (CASE a.CDSX WHEN 1 THEN '国产' WHEN 2 THEN '进口' END), " +

//搜索表名
workParm = mySqlCommand.Parameters.Add("@tableName", SqlDbType.NVarChar, 500);
mySqlCommand.Parameters["@tableName"].Value = " Products a INNER JOIN " +
"Suppliers b ON a.GYS = b.Supplier_No INNER JOIN " +
