mysql - 如何搜索JSON数据关联数组mysql 5.5

Question

我在MySQL 5.5中的表的列中存储了JSON关联数组数据。我想在 JSON 中搜索具有键和值的一个特定数组键我的 JSON 结构:

   {
   "Interface_1":{
      "Caption":"[00000004] Intel(R) Dual Band Wireless-AC 3160",
      "MACAddress":"D0:7E:35:D3:C1:52",
      "DHCPServer":"192.168.1.1",
      "IPAddress":"192.168.1.101",
      "DNSServerSearchOrder":[
         "8.8.8.8",
         "9.9.9.9"
      ],
      "DefaultIPGateway":"192.168.1.1",
      "IPSubnet":"255.255.255.0"
   },
   "Interface_2":{
      "Caption":"[00000011] VMware Virtual Ethernet Adapter for VMnet1",
      "MACAddress":"00:50:56:C0:00:01",
      "IPAddress":[
         "192.168.29.1",
         "fe80::d9f4:2bfa:59f:b9ba"
      ],
      "IPSubnet":[
         "255.255.255.0",
         "64"
      ]
   },
   "Interface_3":{
      "Caption":"[00000013] VMware Virtual Ethernet Adapter for VMnet8",
      "MACAddress":"00:50:56:C0:00:08",
      "IPAddress":[
         "192.168.71.1",
         "fe80::acec:db96:af3a:4680"
      ],
      "IPSubnet":[
         "255.255.255.0",
         "64"
      ]
   }
}

因此，对于按键值搜索，我有以下查询:

SELECT * FROM `extable` 
WHERE network RLIKE '"MACAddress":"[[:<:]]00:50:56:C0:00:08[[:>:]]"'

它工作正常，但我的问题是我无法选择 Interface_1 并在其上搜索 MACAddress。我想选择 Interface_1 并在其上搜索 MACAddress。

Answer 1

您可以将 Interface_1 对象键包含到正则表达式中，从该点开始搜索，但不超过任何 }(对象结尾)字符来查找 MAC 地址:

SELECT * FROM `extable` 
WHERE network RLIKE '"Interface_1":{[^}]*"MACAddress":"[[:<:]]00:50:56:C0:00:08[[:>:]]"'
