如何從 MySQL 中的 Json 多維數組中提取值

Question

列包含下面給出的值。

 [
  {
    "bActive": false,
    "sSubLocation": "",
    "aiSeries": [],
    "iUser": "1"
  },
  {
    "bActive": true,
    "sSubLocation": "Mytestcase",
    "aiSeries": [],
    "iUser": "1"
  }
]

我想將結果作為 sSubLocation 鍵獲得 bActive =true 和 sSubLocation = "Mytestcase";

Answer 1

SELECT test.id, jsontable.*
FROM test
CROSS JOIN JSON_TABLE(test.value,
                      '$[*]' COLUMNS (bActive BOOLEAN PATH '$.bActive',
                                      sSubLocation VARCHAR(255) PATH '$.sSubLocation',
                                      aiSeries JSON PATH '$.aiSeries',
                                      iUser VARCHAR(255) PATH '$.iUser')) jsontable
HAVING bActive = true 
   AND sSubLocation = 'Mytestcase'
