asp.net中如何调用sql存储过程实现分页

2024-03-28 06:22:05 36

首先看下面的代码创建存储过程

1、创建存储过程，语句如下：

CREATEPROCP_viewPage
@TableNameVARCHAR(200),--表名
@FieldListVARCHAR(2000),--显示列名，如果是全部字段则为*
@PrimaryKeyVARCHAR(100),--单一主键或唯一值键
@WhereVARCHAR(2000),--查询条件不含'where'字符，如id>10andlen(userid)>9
@OrderVARCHAR(1000),--排序不含'orderby'字符，如idasc,useriddesc，必须指定asc或desc
--注意当@SortType=3时生效，记住一定要在最后加上主键，否则会让你比较郁闷
@SortTypeINT,--排序规则1:正序asc2:倒序desc3:多列排序方法
@RecorderCountINT,--记录总数0:会返回总记录
@PageSizeINT,--每页输出的记录数
@PageIndexINT,--当前页数
@TotalCountINTOUTPUT,--记返回总记录
@TotalPageCountINTOUTPUT--返回总页数

END
END
PRINT(@Sql)
EXEC(@Sql)
GO

2、SQLServer中调用测试代码

--执行存储过程

declare@TotalCountint,
@TotalPageCountint
execP_viewPage'T_Module','*','ModuleID','','',1,0,10,1,@TotalCountoutput,@TotalPageCountoutput
Select@TotalCount,@TotalPageCount;

asp.net代码实现：

#region===========通用分页存储过程===========
publicstaticDataSetRunProcedureDS(stringconnectionString,stringstoredProcName,IDataParameter[]parameters,stringtableName)
{
using(SqlConnectionconnection=newSqlConnection(connectionString))
{
DataSetdataSet=newDataSet();
connection.Open();
SqlDataAdaptersqlDA=newSqlDataAdapter();
sqlDA.SelectCommand=BuildQueryCommand(connection,storedProcName,parameters);
sqlDA.Fill(dataSet,tableName);
connection.Close();
returndataSet;
}
}
