我有一個輸入csv文件,列的position_Id,Asofdate等必須加載到登臺表中。在我的表中,列Position_Id,AsofDate是主鍵。我們收到了這個輸入文件2個小時。對於Exmaple,我們在今天上午10點收到了File,並將這些文件加載到表格中。再過2個小時後,我們再次收到另一個文件,其中包含與我們在2小時前收回的文件相同的數據,並將數據加載到表格中。SSIS中的增量負載
Now my table contains the data of the file that we recived at 10 Am and 12 pm. At 12:10 pm we received modified input file with different data inside it. Now, my actual requirement is, before the latest input file (12:10 Pm) data is loaded int table, it has to see that only new and updated data has to be loaded into the table.
