我已经整理了一个查询来列出一堆相关数据。下面是查询的简化版本以及示例输出。
SELECT DISTINCT
A.NAME AS APP_NAME,
REPLACE(H.ENVIRONMENT,',','/') AS HOST_ENVIRONMENT,
S.NAME AS SERVER_NAME,
(SELECT
LISTAGG(HS.NAME_1, '/') WITHIN GROUP(ORDER BY HS.NAME_1)
FROM
HOST_SERVER HS
WHERE
HS.NAME_2 = S.NAME
) AS HOST_NAMES,
CASE
WHEN S.LOCATION_ID IN (22,28,59) THEN 'ABC'
WHEN S.LOCATION_ID IN (6,8,9,11,53) THEN 'DBA'
WHEN S.LOCATION_ID IN (5,41,52,43,61) THEN 'ADFS'
WHEN S.LOCATION_ID IN (24,27,24,34,62,63,73) THEN 'ADR'
ELSE NULL
END AS HOST_LOCATION
FROM
APP A
FULL OUTER JOIN APP_HOST AH ON A.ID = AH.ID_1
FULL OUTER JOIN HOST H ON AH.ID_2 = H.ID
FULL OUTER JOIN HOST_SVR HS ON H.ID = HS.ID_1
FULL OUTER JOIN SVR S ON HS.ID_2 = S.ID
GROUP BY
A.NAME,
H.ENVIRONMENT,
S.NAME,
H.NAME,
S.LOCATION_ID,
S.LOCATION
ORDER BY
A.NAME
示例输出(未完成,遗漏了一些不重要的列):
APP_NAME HOST_ENVIRONMENT SERVER_NAME HOST_NAMES
ABCD Production server1 host1/host2/host3
ABCD Production server2 host4/host5/host6
ABCD Development server1 host1/host2/host3
ABCD UBD server2 host4/host5/host6
我想要完成的是基本上按照环境对APP_NAME进行分组。我想要一条生产线和一条生产线(只需称为开发就可以了)。以下是我想要的一个例子:
APP_NAME HOST_ENVIRONMENT SERVER_NAME HOST_NAMES
ABCD Production server1/server2 host1/host2/host3/host4/host5/host6
ABCD Development server1/server2 host1/host2/host3/host4/host5/host6
如何通过环境对这些应用程序进行分组?显然这是一个非常简化的版本,但我正在处理数千行。谢谢你的帮助!

请参阅以下查询,可能对您有用:
CREATE TABLE test(
APP_NAME VARCHAR2(100),
HOST_ENVIRONMENT VARCHAR2(100),
SERVER_NAME VARCHAR2(100),
HOST_NAMES VARCHAR2(100)
);
INSERT INTO test VALUES('ABCD','Production','server1','host1/host2/host3');
INSERT INTO test VALUES('ABCD','Production','server2','host4/host5/host6');
INSERT INTO test VALUES('ABCD','Development','server1','host1/host2/host3');
INSERT INTO test VALUES('ABCD','UBD','server2','host4/host5/host6');
/* CHECK THIS QUERY */
SELECT APP_NAME,HOST_ENVIRONMENT,
listagg(SERVER_NAME,'/' ) WITHIN GROUP (ORDER BY SERVER_NAME) AS SERVER_NAME,
listagg(HOST_NAMES,'/' ) WITHIN GROUP (ORDER BY HOST_NAMES) AS HOST_NAMES
FROM test
GROUP BY APP_NAME,HOST_ENVIRONMENT
试试这个,请看 link
注意:这是分组和concatenacion问题的解决方案,而不是问题的完整解决方案,您必须发布更多信息(例如,表格,数据等)。
我知道这不是一个好的解决方案,但你可以用你的查询替换我的表TEST,我想你会得到你需要的东西。

您可以按多列进行分组,例如按app_name,host_environment分组,然后使用listagg聚合函数将server_names组合成单个字符串。您的数据未显示您希望如何处理app_name列中的多个值。
