我有一个C#方法来执行SQL作业.它成功执行SQL作业.
代码工作得很完美.

我正在使用标准SQL存储过程msdb.dbo.sp_start_job.

这是我的代码..

public int ExcecuteNonquery()
{
     var result = 0;
     using (var execJob =new SqlCommand())
     {
          execJob.CommandType = CommandType.StoredProcedure;
          execJob.CommandText = "msdb.dbo.sp_start_job";
          execJob.Parameters.AddWithValue("@job_name", "myjobname");
          using (_sqlConnection)
          {
               if (_sqlConnection.State == ConnectionState.Closed) 
                  _sqlConnection.Open();

               sqlCommand.Connection = _sqlConnection;
               result = sqlCommand.ExecuteNonQuery();

               if (_sqlConnection.State == ConnectionState.Open) 
                 _sqlConnection.Close();
          }
     }
     return result;
}

这是在作业内执行的sp

ALTER PROCEDURE [Area1].[Transformation]
              AS 
              BEGIN
              SET NOCOUNT ON;

              SELECT NEXT VALUE FOR SQ_COMMON
              -- Transform Master Data
              exec [dbo].[sp_Transform_Address];
              exec [dbo].[sp_Transform_Location];
              exec [dbo].[sp_Transform_Product];
              exec [dbo].[sp_Transform_Supplier];
              exec [dbo].[sp_Transform_SupplierLocation];

              -- Generate Hierarchies and Product References
              exec [dbo].[sp_Generate_HierarchyObject] 'Area1',FGDemand,1;
              exec [dbo].[sp_Generate_HierarchyObject] 'Area1',RMDemand,2;
              exec [dbo].[sp_Generate_Hierarchy] 'Area1',FGDemand,1;
              exec [dbo].[sp_Generate_Hierarchy] 'Area1',RMDemand,2;
              exec [dbo].[sp_Generate_ProductReference] 'Area1',FGDemand,1;
              exec [dbo].[sp_Generate_ProductReference] 'Area1',RMDemand,2;

              -- Transform Demand Allocation BOM 
              exec [Area1].[sp_Transform_FGDemand];
              exec [Area1].[sp_Transform_FGAllocation];
              exec [Area1].[sp_Transform_RMDemand];
              exec [Area1].[sp_Transform_RMAllocation];
              exec [Area1].[sp_Transform_BOM];
              exec [Area1].[sp_Transform_RMDemand_FK];

              -- Transform Purchasing Document Data
              exec [dbo].[sp_Transform_PurchasingDoc];
              exec [dbo].[sp_Transform_PurchasingItem];
              exec [dbo].[sp_Transform_ScheduleLine];


              exec [dbo].[sp_CalculateRequirement] 'Area1'
              exec [dbo].[sp_Create_TransformationSummary] 'Area1'
              -- Trauncate Integration Tables 
              exec [dbo].[sp_TruncateIntegrationTables] 'Area1'

              END

问题是,即使作业成功执行或不成功,它总是返回-1.如何识别作业是否成功执行.

解决方法:

运行msdb.dbo.sp_start_job后,返回代码将映射到输出参数.您有机会在执行之前控制参数的名称：

public int StartMyJob( string connectionString )
{
 using (var sqlConnection = new SqlConnection( connectionString ) )
 {
   sqlConnection.Open( );
   using (var execJob = sqlConnection.CreateCommand( ) )
   {
      execJob.CommandType = CommandType.StoredProcedure;
      execJob.CommandText = "msdb.dbo.sp_start_job";
      execJob.Parameters.AddWithValue("@job_name", "myjobname");
      execJob.Parameters.Add( "@results", SqlDbType.Int ).Direction = ParameterDirection.ReturnValue;      
      execJob.ExecuteNonQuery();
      return ( int ) sqlCommand.Parameters["results"].Value;
    }
  }
}

您需要知道返回代码的数据类型才能执行此操作 – 对于sp_start_job,它是SqlDbType.Int.

但是,这只是启动工作的结果,值得了解,但不是运行工作的结果.要使结果运行,您可以定期执行：
