执行 SQL 任务的 SSIS 2008 R2 OnProgress 日志记录会截断 SQL 语句

Question

我的执行 SQL 任务配置为记录到自动创建的 dbo.sysssislog table。我真的很想在 2K 消息列中记录任何 SQL 语句的全文，但 SSIS 只记录前 40 个字符。有没有办法覆盖该截断？我是否试图解决错误的问题，因为有更好的方法来实现我的目标？

我创建了一个新的（简单的）包来演示我的问题...

执行SQL任务中的表达式

通过 SSIS 生成的过程

将 OnProgress 记录到生成的默认 SSIS table

table中的截断数据（注意省略号）

Answer 1

您所看到的是如何构建默认 OnProgress 记录器的人工制品（以及我从未注意到的东西）。为什么它的结构如此，这对微软来说是一个问题。

如果您显式调用 sp_ssis_addlogentry，那么它会正确地记录最大 nvarchar(2048) 的文本。但是，如果您记录 OnProgress 事件，则传递给存储过程的文本已被事件记录器的内部工作截断。

在您提供的屏幕截图中有两条注意事项。

您正在组件的表达式构建器中构建字符串。我强烈警告不要这样做，因为一个简单的事实，即如果你在那里有一个不正确的表达式，你就没有能力调试它。在对象上设置断点，太棒了。您仍然无法检查您构建的内容的值，因为它在对象内部。相反，我发现我在一个变量中构建所有字符串更成功，然后我的任务表达式只是 @[MyVariable]
在 2012 版之前，表达式有 4k 个字符的限制。您可以初始化和分配大于该长度的字符串，但如果您尝试使用表达式来执行此操作，则它不起作用。我现在不记得它是截断还是完全失败。

第 1 轮，脚本方法

我创建了两个 SSIS 变量：Query 和 QueryLength。 Query的Value是SSMS

中我运行下面的查询

SELECT REPLICATE('SELECT 100 AS col UNION ALL ', 70) + ' SELECT 0'

查询是一个使用以下表达式的整数值：LEN(@[User::Query]) 它的值应为 1968

我在我的包中添加了一个脚本任务并使用了以下代码

using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;

namespace ST_b3643f349be14c7a9d004a35aaa0422e
{
    [Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute]
    public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
    {

        public void Main()
        {
            // User::Query,User::QueryLength
            string query = this.Dts.Variables["User::Query"].Value.ToString();
            string queryLength = this.Dts.Variables["User::QueryLength"].Value.ToString();

            bool fireAgain = false;
            string message = string.Format("Query => {0}", query);
            this.Dts.Events.FireInformation(0, "Query", message, string.Empty, 0, ref fireAgain);
        this.Dts.Events.FireProgress(message, 50, 0, 1, "query", ref fireAgain);

            message = string.Format("QueryLength => {0}", queryLength);
            this.Dts.Events.FireInformation(0, "QueryLength", message, string.Empty, 0, ref fireAgain);
        this.Dts.Events.FireProgress(message, 50, 0, 1, "queryLength", ref fireAgain);

            Dts.TaskResult = (int)ScriptResults.Success;
        }

        enum ScriptResults
        {
            Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
            Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
        };
    }
}

最后，我打开了登录到 SQL 服务器并记录了 OnInformation 和 OnProgress 事件

我执行了包，然后运行下面的查询

USE msdb
SELECT
    S.source
,   S.event
,   LEN(S.message) AS lenMsg
,   S.message
FROM
    dbo.sysssislog AS S
WHERE
    S.event = 'OnInformation'
    OR S.event = 'OnProgress';

如您所见，它记录了 40 多个字符。

第二轮，执行SQL任务方法

根据下面的评论，我修改了程序包以使用调用 sp_ssis_addlogentry 的执行 SQL 任务我仍然将完整消息记录到 message 列dbo.sysssislog

这导致生成此包。

包运行时运行探查器跟踪的结果

    N'exec sp_ssis_addlogentry @P1, @P2, @P3, @P4, @P5, @P6, @P7, @P8, @P9, @P10, @P11'

,   N'Executing query "EXECUTE dbo.sp_ssis_addlogentry

这与手动生成的对 sp_ssis_logentry
