在 SSIS 中,我有一个查找转换,它执行仅将新数据插入表的功能,称为 tableY。所以过程如下:
0) Aggregate (group by) the primary key for the input row
1) Do a lookup with the current input row on tableY using the primary key
2) Insert the input row if there is not a match (the current row does not exist in tableY)
我收到“违反主键列的完整性约束”的错误
这怎么可能,因为所有输入都是唯一的,并且转换的输出是“查找不匹配输出”?
