SQL Server：テーブル変数の更新

Question

SQL Serverで四半期ごとにグループ化された3列のデータを含むテーブル変数を作成しようとしています。 3つの列のそれぞれに適切なデータを選択することに成功しましたが、追加のクエリごとにテーブル変数の内容を更新する方法はわかりません。

したがって、4つの行（四半期ごとに1つ）と3つのデータ列を持つ表ではなく、データ列に12行（4/4が3回重複しています）と多数のNULLがあります。

NULLSなしでテーブルの4行のみのバージョンを作成するにはどうすればよいですか？

クエリ：クエリから設定

DECLARE @temp TABLE (oYear INT, oQuarter INT, chin FLOAT, press FLOAT, pull FLOAT) 
DECLARE @sDate AS DATE, @eDate AS DATE, @athName AS VARCGAR(50), 
     @chin1RM AS FLOAT, @press1RM AS FLOAT, @pull1RM AS FLOAT; 

SET @sDate = '2016-10-01'; 
SET @eDate = '2017-10-01'; 

SET @athName = 'Steve'; 

INSERT INTO @temp (oYear, oQuarter, chin) 
    SELECT 
     DATEPART(YEAR, Day.Date), 
     DATEPART(QUARTER, Day.Date), 
     MAX(Pred1RMBMF) 
    FROM 
     GymLoad 
    JOIN 
     Session ON Session.id = GymLoad.SessionID 
    JOIN 
     Day ON Day.id = Session.DayID 
    JOIN 
     Athlete ON Athlete.id = Day.AthleteID 
    WHERE 
     (ExerciseID = 200 OR ExerciseID = 198) 
     AND FullName = @athName 
     AND Day.Date >= @sDate 
     AND Day.Date <= @eDate 
    GROUP BY 
     DATEPART(YEAR,Day.Date), DATEPART(QUARTER,Day.Date); 

INSERT INTO @temp (oYear, oQuarter, press) 
    SELECT 
     DATEPART(YEAR, Day.Date), 
     DATEPART(QUARTER, Day.Date), 
     MAX(Pred1RMBMF) 
    FROM 
     GymLoad 
    JOIN 
     Session ON Session.id = GymLoad.SessionID 
    JOIN 
     Day ON Day.id = Session.DayID 
    JOIN 
     Athlete ON Athlete.id = Day.AthleteID 
    WHERE 
     (ExerciseID = 164 OR ExerciseID = 174) 
     AND FullName = @athName 
     AND Day.Date >= @sDate 
     AND Day.Date <= @eDate 
    GROUP BY 
     DATEPART(YEAR, Day.Date), DATEPART(QUARTER, Day.Date); 

INSERT INTO @temp (oYear, oQuarter, pull) 
    SELECT 
     DATEPART(YEAR, Day.Date), 
     DATEPART(QUARTER, Day.Date), 
     MAX(Pred1RMBMF) 
    FROM 
     GymLoad 
    JOIN 
     Session ON Session.id = GymLoad.SessionID 
    JOIN 
     Day ON Day.id = Session.DayID 
    JOIN 
     Athlete ON Athlete.id = Day.AthleteID 
    WHERE 
     (ExerciseID = 183 OR ExerciseID = 183) 
     AND FullName = @athName 
     AND Day.Date >= @sDate 
     AND Day.Date <= @eDate 
    GROUP BY 
     DATEPART(YEAR, Day.Date), DATEPART(QUARTER, Day.Date); 

SELECT * FROM @Temp 

現在返される結果：

oYear oQuarter chin press pull 
------------------------------------------ 
2017 1   104.02 NULL NULL 
2017 2   102.22 NULL NULL 
2017 3   100.54 NULL NULL 
2016 4   104.3 NULL NULL 
2017 1   NULL  81.61 NULL 
2017 2   NULL  71.26 NULL 
2017 3   NULL  75.86 NULL 
2016 4   NULL  80  NULL 
2017 1   NULL  NULL 91.95 
2017 2   NULL  NULL 68.97 
2017 3   NULL  NULL 73.75 
2016 4   NULL NULL 85.33

年および四半期ごとに集計し、データ列に集計関数（例：MAX）を使用してNULLを削除します。

SELECT 
    oYear, 
    oQuarter, 
    MAX(chin) AS chin, 
    MAX(press) AS press, 
    MAX(pull) AS pull 
FROM @Table 
GROUP BY 
    oYear, 
    oQuarter;
