將json插入Postgres中表的字段數組

Question

PHP向我返回json：

{          
      "date"    : "2014-02-06",
      "typeDate": "local",
      "events"  : [
                    "To get know how Sherlock survived",
                    "Find who killed the President Kennedy",
                    "Cook met"
                  ]
       }

我需要將此對象插入具有此類對象數組的表字段中：

{
     "dates": [   
     {          
      "date"    : "2014-02-06",
      "typeDate": "local",
      "events"  : [
                "Kill John Connor",
                "Kill T-1000",
                "Listen Moon sonata"
              ]
     },
     {        
      "date"    : "2014-02-07",
      "typeDate": "local",
      "events"  : [
                "Fix Enstain's theory",
                "Take pizza"
              ]
       }
   ]
}

如何做到這一點正確？ 嘗試使用示例

INSERT INTO aa VALUES (1, 'my_json_record');

我收到有關json結構的錯誤。

Answer 1

通常，您應該先序列化JSON對象，然后再插入數據庫。

 $my_json_var = json_decode($my_json_record)

此方法使用JSON編碼的字符串並將其轉換為PHP變量。 參見http://us2.php.net/json_decode

然后建立您的查詢...

 $sql = "INSERT INTO aa (field1, field2) VALUES (1, '$my_json_var')";
