SSIS转型(几乎像一个支点)

我有以下数据进入SSIS

Set   Value
---   -------
1     One
1     Two
1     Three
2     Four
2     Five
2     Six

我想将其转换为阅读

Set   ValueList
---   -------
1     One, Two, Three
2     Four, Five, Six

我如何在SSIS中执行此操作?

数据流转换中有一个数据透视任务。你可以尝试一下,但我会警告你,我们对它的执行情况不太满意。

或者,您可以使用数据流将数据放入登台表,并使用SQL进行透视或在用于创建传入数据源的SQL中执行透视。如果您想在SQl代码中执行此操作,这可能会有所帮助:

select 1 as Item 
into #test 
union select 2 
union select 3 
union select 4 
union select 5 

select STUFF((SELECT  ', ' + cast(Item as nvarchar) 
        FROM #test 
        FOR XML PATH('')), 1, 1, '')

我使用Script Component跨行进行字符串连接

string TagId = "-1";
string TagList = "";
bool IsFirstRow = true;

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    if (Row.TAGSId.ToString() == TagId)
    {
        TagList += Row.TAG + ",";
    }
    else
    {
        if (IsFirstRow)
        {
            Output0Buffer.AddRow();
            IsFirstRow = false;
        }

        TagId = Row.TAGSId.ToString();
        TagList = Row.TAG.ToString() + ",";
    }

    Output0Buffer.TagId = int.Parse(TagId);
    Output0Buffer.TagList = TagList;
    Output0Buffer.TagLength = TagList.Length;

    //variable used in subsequent queries
    this.Variables.TagList = TagList;
}
