Hi, How to append a new dataset to the old dataset (only new records/rows)? I have dataset one, cid is the key. Then there is the second dataset, same column number, same data structure, cid is also the key. (cid means contracts id) So now I hope to do this: If the contracts in the second dataset are not in the old dataset, then append these contracts (these rows) to the old dataset. Basically, I updated the table by adding the new contracts. Thank you so much.
