如何在Postgres中导入JSON文件

Question

我正在尝试将json文件导入PostgreSQL。 示例数据：

 {
  "asin":"2094869245",
  "title":"5 LED Bicycle Rear Tail Red Bike Torch Laser Beam Lamp Light",
  "price":8.26,
  "imhUrl":"http://ecx.images-amazon.com/images/I/51RtwnJwtBL._SY300_.jpg"
 }

 {
  "asin":"7245456259",
  "title":"Black Mountain Products Single Resistance Band - Door Anchor,
  "price":10.49,
  "imhUrl":"http://ecx.images-amazon.com/images/I/411Ikpf122L._SY300_.jpg"
 }`

希望结果看起来像：

data
--------------------------------------------------------------------
{
  "asin":"2094869245",
  "title":"5 LED Bicycle Rear Tail Red Bike Torch Laser Beam Lamp Light",
  "price":8.26,
  "imhUrl":"http://ecx.images-amazon.com/images/I/51RtwnJwtBL._SY300_.jpg"
}

--------------------------------------------------------------------
{
  "asin":"7245456259",
  "title":"Black Mountain Products Single Resistance Band - Door Anchor,
  "price":10.49,
  "imhUrl":"http://ecx.images-amazon.com/images/I/411Ikpf122L._SY300_.jpg"
}

数据是json类型。

我的JSON FILE将存储在一个名为data的JSON列中。

如果您像这样删除JSON文件中的换行符：

{ "asin":"2094869245", "title":"5 LED Bicycle Rear Tail Red Bike Torch Laser Beam Lamp Light","price":8.26,  "imhUrl":"http://ecx.images-amazon.com/images/I/51RtwnJwtBL._SY300_.jpg"}
{ "asin":"7245456259",  "title":"Black Mountain Products Single Resistance Band - Door Anchor",  "price":10.49,  "imhUrl":"http://ecx.images-amazon.com/images/I/411Ikpf122L._SY300_.jpg" }

您可以使用copy命令加载到表中：

create table js (a json);

copy js from '/tmp/data.json'  DELIMITER '^'  CSV  QUOTE ''''  ESCAPE '\'
