MySQL/MariaDB JSON_EXTRACT 和 JSON_CONTAINS

Question

我有一个 table 结构如下：

select * from test_table;

id |load_balancer_name |listener_descriptions                                                                                                                                                                                       |
---|-------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
1  |with_cert_1        |[{"Listener": {"Protocol": "HTTPS", "LoadBalancerPort": 443, "InstanceProtocol": "HTTP", "InstancePort": 9005, "SSLCertificateId": "arn:aws:acm:us-west-2:xxxx:certificate/xxx"}, "PolicyNames": ["xxxx"]}] |
2  |with_cert_1        |[{"Listener": {"Protocol": "HTTPS", "LoadBalancerPort": 443, "InstanceProtocol": "HTTP", "InstancePort": 9005, "SSLCertificateId": "arn:aws:acm:us-west-2:xxxx:certificate/xxx"}, "PolicyNames": ["xxxx"]}] |
3  |with_cert_2        |[{"Listener": {"Protocol": "HTTPS", "LoadBalancerPort": 443, "InstanceProtocol": "HTTP", "InstancePort": 9005, "SSLCertificateId": "arn:aws:acm:us-west-2:xxxx:certificate/yyy"}, "PolicyNames": ["xxxx"]}] |
4  |no_cert            |                                                                                                                                                                                                            |

我需要的是根据 listener_descriptions 列进行一些搜索。为了确保 JSON_* 方法有效，我做了这个查询，效果很好：

select 
id, load_balancer_name,
JSON_EXTRACT(listener_descriptions, "$[*].Listener.SSLCertificateId")
from test_table;

id |load_balancer_name |JSON_EXTRACT(listener_descriptions, "$[*].Listener.SSLCertificateId") |
---|-------------------|----------------------------------------------------------------------|
1  |with_cert_1        |["arn:aws:acm:us-west-2:xxxx:certificate/xxx"]                        |
2  |with_cert_1        |["arn:aws:acm:us-west-2:xxxx:certificate/xxx"]                        |
3  |with_cert_2        |["arn:aws:acm:us-west-2:xxxx:certificate/yyy"]                        |
4  |no_cert            |                                                                      |

现在我想 select 所有匹配的行 SSLCertificateId:

select 
*
from test_table
where JSON_CONTAINS(listener_descriptions, '"arn:aws:acm:us-west-2:xxxx:certificate/xxx"', "$[*].Listener.SSLCertificateId")
;

但是没有找到结果。我尝试在 JSON_CONTAINS 的第二个参数中使用单引号和双引号的多种组合，但没有成功。

Answer 1

JSON_CONTAINS() 不允许在其路径中使用 [*]。相反，使用 JSON_EXTRACT() 提取所有证书的数组，并在其上使用 JSON_CONTAINS()。

select *
FROM test_table
WHERE JSON_CONTAINS(JSON_EXTRACT(listener_descriptions, "$[*].Listener.SSLCertificateId"), '"arn:aws:acm:us-west-2:xxxx:certificate/xxx"')
;
