这是我的第一个查询，它给出了与工资相关的实际和估计费用总和

SELECT
  d.y_                                   AS `salaries`
 , IFNULL(SUM(d.actual),0)               AS `Estimated`

GROUP
     BY YEAR(it.Date_expenses_table)
) d
 GROUP

ORDER

Answer 1

您可以使用UNION合并这些查询：

SELECT [First query]
UNION ALL 
SELECT 'Equipments', 'Estimated', 'Actual'
UNION ALL
SELECT [Second query]

请注意，在第一个UNION ALL之后选择只会选择第二个查询的标题。你也可以使用UNION（没有全部），因为它看起来不像你有重复。

Answer 2

如果你有重复的注册表并且不想看到它们，你可以使用UNION ALL。如果你不介意重复的注册表，你可以使用UNION。这是和示例

SELECT [query_1] UNION ALL SELECT [query_2] UNION ALL SELECT [query_3]

我想合并两个查询有一个结果
