1.后台调用带参数的存储过程详解
例：
注明：@AnalysisDate，@Process_PTR为存储过程参数
IDataParameter[] iDataDi = new SqlParameter[2]; iDataDi[0] = new SqlParameter("@AnalysisDate", showDate); iDataDi[1] = new SqlParameter("@Process_PTR", ID); //获取检测项所选日期的不同时间 dtDifferTime = SqlHelper.RunProceduresByParameter("pro_GetDifferenceTimeInfos", iDataDi); //SqlHelper中的 RunProceduresByParameter(string storedProcName, IDataParameter[] parameters)方法： /// <summary> /// 执行带参数的存储过程，返回DataSet类型 /// </summary> /// <param></param> /// <param></param> /// <returns></returns> public static DataSet RunProceduresByParameter(string storedProcName, IDataParameter[] parameters) { using (SqlConnection connection = new SqlConnection(connectionString)) { DataSet dataSet = new DataSet(); connection.Open(); SqlDataAdapter sqlDA = new SqlDataAdapter(); sqlDA.SelectCommand = BuildQueryCommand(connection, storedProcName, parameters); sqlDA.Fill(dataSet); connection.Close(); connection.Dispose(); return dataSet; } } /// <summary> /// 构建 SqlCommand 对象(用来返回一个结果集，而不是一个整数值) /// </summary> /// <param>数据库连接</param> /// <param>存储过程名</param> /// <param>存储过程参数</param> /// <returns>SqlCommand</returns> private static SqlCommand BuildQueryCommand(SqlConnection connection, string storedProcName, IDataParameter[] parameters) { SqlCommand command = new SqlCommand(storedProcName, connection); command.CommandType = CommandType.StoredProcedure; foreach (SqlParameter parameter in parameters) { command.Parameters.Add(parameter); } return command; }
2.存储过程创建语句
USE [RedBSys_DB] GO /****** Object: StoredProcedure [dbo].[pro_GetDifferenceTimeInfos] Script Date: 2017-03-22 16:34:13 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO --获取检测项当天日期不同时间 CREATE proc [dbo].[pro_GetDifferenceTimeInfos] @AnalysisDate varchar(50), @Process_PTR int AS select distinct(AnalysisDate) from Assay_BillMain where CONVERT(varchar(100),AnalysisDate, 23)=@AnalysisDate and Process_PTR=@Process_PTR order by AnalysisDate ASC GO
