Question

我在SSIS下创建了Logging，它在我的数据库的系统表中生成为[dbo].[sysssislog]。我试图获取Id，Source，starttime，endtime和message等特定列到另一个SQL Server表，client.EximLog和Client.EximLogHistory。

每次运行包时都会抛出以下错误：

at System.Data.SqlClient.SqlConnection.OnError（SqlException异常，Boolean breakConnection，Action1 wrapCloseInAction）在System.Data.SqlClient.SqlInternalConnection.OnError（SqlException异常，Boolean breakConnection，Action1 wrapCloseInAction）在System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning（TdsParserStateObject stateObj，Boolean callerHasConnectionLock，Boolean asyncClose）在System.Data.SqlClient.TdsParser.TryRun（RunBehavior runBehavior，SqlCommand cmdHandler，SqlDataReader dataStream，BulkCopySimpleResultSet bulkCopyHandler，TdsParserStateObject stateObj，Boolean＆amp; dataReady）在System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds（String methodName，Boolean async，Int32 timeout，Boolean asyncWrite） at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery（TaskCompletionSource`1 completion，String methodName，Boolean sendToPipe，Int32 timeout，Boolean＆amp; usedCache，Boolean asyncWrite，Boolean inRetry）在System.Data.SqlClient.SqlCommand.ExecuteNonQuery（）在ScriptMain.Input0_ProcessInputRow（Input0Buffer Row）在UserComponent.Input0_ProcessInput（Input0Buffer Buffer） at UserComponent.ProcessInput（Int32 InputID，String InputName，PipelineBuffer Buffer，OutputNameMap OutputMap）在Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.ProcessInput（Int32 InputID，PipelineBuffer buffer）在Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput（Int32 inputID，PipelineBuffer buffer）

我创建了一个事件处理程序'Onerror'来执行数据流任务，比如说'连接到SSIS日志表'。

在数据流任务中，我使用OLD DB Connection连接到sysssislog表。

SELECT Id, source, starttime, endtime, message 
FROM dbo.sysssislog
WHERE event = 'onerror' AND ID NOT IN (SELECT ISNULL(cast(LogId as int), 0)  FROM [Client].[EximLog])

我已将OLD DB源连接连接到Script组件作为Destination。我正在执行以下存储过程。

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[spEximLog]
--Add parameters for the stored procedure
    @pSystemID nvarchar(max) = NULL,
    --@sEvent nvarchar(max) = NULL,
    @pSource nvarchar(max) = NULL,
    @pStarttime nvarchar(max) = NULL,
    @pEndtime nvarchar(max) = NULL,
    @pMessage nvarchar(max) = NULL
    WITH EXECUTE AS OWNER
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @vJoboutcome nvarchar(max);
    DECLARE @vGUID nvarchar(40);
    DECLARE @vTimeStamp timestamp;
    DECLARE @vEximID int;
    DECLARE @vDefaultOperation nvarchar(40);
    DECLARE @vDefaultEventRegistrationId int;
    DECLARE @vDefaultVersion int;

    SET @vJoboutcome = 'F';
    SET @vDefaultOperation = 'Insert';
    SET @vDefaultEventRegistrationId = 1;
    SET @vDefaultVersion = 1;


    IF NOT EXISTS (SELECT * FROM [dbo].[sysssislog] WHERE ID = @pSystemID)

    BEGIN

        SET @vGUID = CAST((SELECT NEWID()) as nvarchar(40));

        --Inserting 8 cloumns into Exim table
        INSERT INTO [Client].[EXIMLog]
        (
          [JobName], [JobMessage], [JobOutCome], [LogID], [DtmJobStart], [DtmJobEnd]
        , [EventRegistrationId], [ObjectId]
        )

        VALUES(@pSource, @pMessage, @vJoboutcome, @pSystemID, @pStarttime, @pEndtime
        , @vDefaultEventRegistrationId, @vGUID);

        SET @vEximID = (SELECT @@IDENTITY); /*Same EximId is used in Malvern import and in its history table*/

        --Stores the timestamp for the row using where clause
        SET @vTimeStamp = (SELECT [TimeStamp] from [Client].[EXIMLog] where Id = @vEximId);


        --Inserting 12 cloumns into Exim History table
        INSERT INTO [Client].[EXIMLogHistory]
        (
          [Id], [Version], [JobName], [JobMessage], [JobOutCome], [LogID], [DtmJobStart]
        , [DtmJobEnd], [EventRegistrationId], [ObjectId], [Operation], [TimeStamp]
        )
        VALUES(@vEximID, @vDefaultVersion, @pSource, @pMessage, @vJoboutcome, @pSystemID,  @pStarttime, @pEndtime, @vDefaultEventRegistrationId, @vGUID
        , @vDefaultOperation, CAST(@vTimeStamp as varbinary));
    END
END;
GO

以下是我在脚本组件中使用的脚本，连接管理器是ADO.net连接。

#region Namespaces
using System;
using System.Data.SqlClient;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
#endregion

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    System.Data.SqlClient.SqlConnection conn =
        (System.Data.SqlClient.SqlConnection)Connections.SecondConnection.AcquireConnection(null);
    System.Data.SqlClient.SqlCommand cmd = new
        System.Data.SqlClient.SqlCommand("Exec [dbo].[spEximLog]'" + Row.Id + "', '" + Row.source + "', '" + Row.starttime +"', '" + Row.endtime + "' , '" + Row.message + "'", conn);
    cmd.ExecuteNonQuery();
}

更改脚本组件代码如下并解决了问题。

public override void PostExecute()
    {
        base.PostExecute();

        conn.Close();

    }

public override void Input0_ProcessInputRow(Input0Buffer Row)
    {
        if(conn.State != System.Data.ConnectionState.Open)
        {
            conn.Open();
        }
        System.Data.SqlClient.SqlCommand cmd = new
            System.Data.SqlClient.SqlCommand("[dbo].[spEximLog]", conn);
        cmd.CommandType = System.Data.CommandType.StoredProcedure;
        cmd.Parameters.Add(new SqlParameter("@pSystemID", Row.Id));
        cmd.Parameters.Add(new SqlParameter("@pSource", Row.source));
        cmd.Parameters.Add(new SqlParameter("@pstarttime", Row.starttime));
        cmd.Parameters.Add(new SqlParameter("@pendtime", Row.endtime));
        cmd.Parameters.Add(new SqlParameter("@pmessage", Row.message));

        cmd.ExecuteNonQuery();
    }

独立分配参数。在post执行中关闭连接，以便它不会达到最大连接池。
