sql-server - UNION への条件の追加

Question

私は長く複雑なクエリに取り組んでいます:

生成して行タイプ 3 に入れることができる行が 2 つあります。それらの間には UNION があるため、両方の結果が表示されますが、重複は表示されません。これは期待どおりに機能していますが、すべてのセルが行間で合計されるわけではないため、行の 2 つのバージョンが表示される場合があります。これが発生した場合、最後のセルが大きい（合計列）行を表示したいだけです。

どうすればこれを達成できますか?

編集（明確にする試み）：

私は時々同じ人のために2つの行になるユニオンを持っています:

これが発生した場合、両方ではなく合計が高い行を表示したいだけです。それ、どうやったら出来るの？

提案で更新されました..それでも同じ結果が得られます。なにが問題ですか？
