Question

我之前设法做到了但是不记得怎么也找不到答案：我正在尝试在数据库中查询sum（）并将结果传播到2行例如sum（男性）为'男性'，sum（女性）为'女性'，sum（男性+女性）为'总' 新行总和（年龄> 45岁的男性），总和（年龄> 45岁的女性），总和（男性+女性超过45岁）为“总计” 我确信这很简单但很烦我，请帮忙

尝试类似......

SELECT SUM(CASE WHEN Age <=45 THEN MEN       ELSE 0 END) AS Men
      ,SUM(CASE WHEN Age <=45 THEN WOMEN     ELSE 0 END) AS Women
      ,SUM(CASE WHEN Age <=45 THEN Men+WOMEN ELSE 0 END) AS Total
      ,'45 or Under'                                     AS AgeGroup
FROM Table
UNION ALL
SELECT SUM(CASE WHEN Age > 45 THEN MEN       ELSE 0 END) AS Men
      ,SUM(CASE WHEN Age > 45 THEN WOMEN     ELSE 0 END) AS Women
      ,SUM(CASE WHEN Age > 45 THEN Men+WOMEN ELSE 0 END) AS Total
      ,'above 45'                                        AS AgeGroup
FROM Table

或者你可以做一些......

SELECT SUM(MEN)       AS Men
      ,SUM(WOMEN)     AS Women
      ,SUM(Men+WOMEN) AS Total
      ,'45 or Under'  AS AgeGroup
FROM Table WHERE Age <= 45
UNION ALL
SELECT SUM(MEN)       AS Men
      ,SUM(WOMEN)     AS Women
      ,SUM(Men+WOMEN) AS Total
      ,'45 or Under'  AS AgeGroup
FROM Table WHERE Age > 45

SQL查询结果超过两行
