将json插入Postgres中表的字段数组中

Question

PHP将json返回给我：

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

我需要将此对象插入到包含此类对象数组的表的字段中：

{
     "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"
              ]
       }
   ]
}

如何做到这一点？试图使用示例

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

我收到了关于json结构的错误。

基本上你可以在插入数据库之前序列化JSON对象。

 $my_json_var = json_decode($my_json_record)

这个methond采用JSON编码的字符串并将其转换为PHP变量。见http://us2.php.net/json_decode

然后构建您的查询......

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