问题描述
我有以下数据进入 SSIS
I have the following data coming in to SSIS
Set Value
--- -------
1 One
1 Two
1 Three
2 Four
2 Five
2 Six
我想把它转换成阅读
Set ValueList
--- -------
1 One, Two, Three
2 Four, Five, Six
如何在 SSIS 中执行此操作?
How do I do this in SSIS?
推荐答案
我使用脚本组件进行跨行的字符串连接
I used the Script Component to do the string concatenation across rows
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;
}
