在一个sql查询输出中包含排除

Question

MainAccountID 是一棵树的根，该树可以有许多帐户，每个帐户可以有许多城市节点，每个子城市节点可以有许多城市。

有一个表ConfigFlow.tb，其中每个条目代表特定的流信息，需要使用包含和排除城市Id来创建

ConfigFlow.tb
MainAccountID,IncludeMainCityId,ExcludeMainCityId
1100,100,200
1200,200,300

AccountIds.tb

AccountId,MainAccountID
1,1100
2,1100
3,1200

城市 ID.tb

CityId,MainCityId 
11,100
12,100
13,200
14,300

将 ConfigFlow.tb 与 AccountIds.tb（在 MainAccountID 上）内连接以获取所有子帐户节点，然后与 CityIds.tb 内连接以获取 IncludeMainCityId 下的所有 Cityid

Output only for IncludeMainCityId
1100,100,200,   1,1100,     11,100
1100,100,200,   2,1100,     12,100
1200,200,300,   3,1200,     13,200

有没有办法编写sql查询来同时获取 IncludeMainCityId,ExcludeMainCityId 的输出，像这样？

{ConfigFlow.tb}     {AccountIds.tb}     {IncludeCityIds}    {ExcludeCityIds}
1100,100,200,       1,1100,             11,100               0,0
1100,100,200,       2,1100,             12,100               0,0
1200,200,300,       3,1200,             13,200               0,0
1100,100,200,       1,1100,             0,0                  13,200
1200,200,300,       3,1200,             0,0,                 14,300 

Note:

没有提到所有列名称，但提到了表名称（只是为了避免编写太多有问题的列，但每个逗号分隔都是提到的特定表的一个列）

Answer 1

您可以通过

JOIN

IncludeMainCityId

表格，然后通过

UNION ALL

再次使用

JOIN

和

ExcludeMainCityId

表格：

SELECT cf.*,
       a.AccountId,
       ic.CityId AS IncludeCityId,
       ic.MainCityId AS IncludeMainCityId,
       0 AS ExcludeCityId,
       0 AS ExcludeMainCityId
FROM   configflow cf
       INNER JOIN accountids a
       ON cf.mainaccountid = a.mainaccountid
       INNER JOIN cityids ic
       ON cf.IncludeMainCityId = ic.MainCityId
UNION ALL
SELECT cf.*,
       a.AccountId,
       0,
       0,
       ec.CityId,
       ec.MainCityId
FROM   configflow cf
       INNER JOIN accountids a
       ON cf.mainaccountid = a.mainaccountid
       INNER JOIN cityids ec
       ON cf.ExcludeMainCityId = ec.MainCityId;

对于样本数据：

CREATE TABLE ConfigFlow (MainAccountID,IncludeMainCityId,ExcludeMainCityId) AS
SELECT 1100,100,200 FROM DUAL UNION ALL
SELECT 1200,200,300 FROM DUAL;

CREATE TABLE AccountIds (AccountId,MainAccountID) AS
SELECT 1,1100 FROM DUAL UNION ALL
SELECT 2,1100 FROM DUAL UNION ALL
SELECT 3,1200 FROM DUAL;

CREATE TABLE CityIds (CityId,MainCityId) AS
SELECT 11,100 FROM DUAL UNION ALL
SELECT 12,100 FROM DUAL UNION ALL
SELECT 13,200 FROM DUAL UNION ALL
SELECT 14,300 FROM DUAL;

输出：

主帐户ID	包括城市 ID	排除EMANCITYID	账号	包含城市ID	包括城市 ID	排除城市ID	排除EMANCITYID
1100	100	200	1	11	100	0	0
1100	100	200	2	11	100	0	0
1100	100	200	1	12	100	0	0
1100	100	200	2	12	100	0	0
1200	200	300	3	13	200	0	0
1100	100	200	1	0	0	13	200
1100	100	200	2	0	0	13	200
1200	200	300	3	0	0	14	300
