在 SELECT 中将两个列表联合在一起

Question

如何将两个表合并为一个不包含主键的新表？

例如：

第一个表：

Team_Code           ID
----------------------------------
433                 203994834
436                 203994834 
436                 309228372
435                 309228373
434                 309228374
433                 399064113

第二个表：

number_of_times       Team_Code
------------------------------------
3                     433
2                     434
1                     435
1                     436

输出的第一行应如下所示：

number_of_times    Team_Code      ID
---------------------------------------------
3                  433            203994834
2                  434            309228374  
1                  435            309228373
1                  436            203994834

Answer 1

; with 
query1 as
(
-- Your Query 1
SELECT * FROM Fireman_Team WHERE Team_Code in (
  SELECT Answer.Team_Code FROM Answer WHERE
  Answer.Call_Number IN(
    SELECT Call_Number FROM (SELECT * FROM Call WHERE Call.Time_Started
      BETWEEN ('2016-01-01 00:00:00') AND 
      ('2016-01-31 23:59:59')) AS SSS)) 
),
query2 as
(
-- Your Query 2
SELECT COUNT(Team_Code) as number_of_times, 
Team_Code FROM (SELECT Answer.Team_Code FROM Answer WHERE
  Answer.Call_Number IN(
    SELECT Call_Number FROM (SELECT * FROM Call WHERE Call.Time_Started
      BETWEEN ('2016-01-01 00:00:00') AND 
      ('2016-01-31 23:59:59')) AS SSS)
) AS re GROUP BY Team_Code
)
select *
from   query1 q1 inner join query2 q2 on q1.Team_Code = q2.Team_Code

Answer 2

使用 CTE 提高可读性 -

WITH CTE1 AS 
(
SELECT [Team_Code],[ID] FROM Fireman_Team WHERE Team_Code in (
  SELECT Answer.Team_Code FROM Answer WHERE
  Answer.Call_Number IN(
    SELECT Call_Number FROM (SELECT * FROM Call WHERE Call.Time_Started
      BETWEEN ('2016-01-01 00:00:00') AND 
      ('2016-01-31 23:59:59')) AS SSS)) 
)

;WITH CTE2 AS
(
SELECT COUNT(Team_Code) as number_of_times, 
Team_Code FROM (SELECT Answer.Team_Code FROM Answer WHERE
  Answer.Call_Number IN(
    SELECT Call_Number FROM (SELECT * FROM Call WHERE Call.Time_Started
      BETWEEN ('2016-01-01 00:00:00') AND 
      ('2016-01-31 23:59:59')) AS SSS)
) AS re GROUP BY Team_Code
)

SELECT b.[number_of_times], b.[Team_Code], a.[ID]
FROM CTE1 a
INNER JOIN CTE2 b
ON a.[Team_Code] = b.[Team_Code]
