組合での集計すべて

Question

従業員は1週間に最大3つのプロジェクトに関わり、各プロジェクトでは2つの異なるタスクを実行できます。 私はunion allを使用して1つのテーブルから別々のフィールドに参加していますので、実行されたタスクごとに別々の行が表示されます（従業員1人あたり最大6行）。最終的にシステム内の時計に参加するので、各従業員に支払う金額を特定のプロジェクトのタスクに割り当てることができ、お金がどこにあるかをより正確に把握することができます。

私は分割する番号があるので、タスクの量を数えて（各従業員の行数を数える）手段が必要です。

私はいくつかの場所でグループを試してみましたが、1つしか表示されません（おそらく選択範囲内に一意のフィールドがないためです。

特定のフィールドでカウントを行うべきですか？または別の方法がありますか？

私はCOUNT(*) OVER (PARTITION BY SAGEID, A.EmployeeID) AS RC を追加し、ジャンがあまりにもhttps://stackoverflow.com/help/mcveを読んで、
