使用 MS SQL Server 读取包含多个 JSON 对象的文件 [英] Reading file containing multiple JSON objects using MS SQL Server

问题描述

我需要帮助在 MSSQL 中读取 JSON 文件

I need help reading JSON file in MSSQL

我有一个这样的json格式

I have a json format like this

{ 
   "_id":{ 
      "$oid":"5c6ceb395916c77f71d9f531"
   },
   "uuid":"8337df01-7d98-4cdd-b5eb-7fafa88d3740",
   "firstName":"TESTFN",
   "lastName":"TESTLN",
   "middleName":"TESTMN",
   "gender":"MALE",
   "nationality":"",
   "mobileNumber":"",
   "card":"TACC-00001",
   "claims":{ 
      "$numberLong":"1"
   },
   "hisId":{ 
      "$numberLong":"0"
   },
   "hospitals":[ 
      { 
         "$ref":"hospital",
         "$id":{ 
            "$oid":"5bd80e4e36ec8c600f3e750a"
         }
      }
   ]
}

我正在尝试使用以下代码读取 json.它工作正常.但是当我使用重复上述格式并且有很多字段的确切源文件时，我只检索一行.

I'm trying to read json using below code. It is working fine. But when I use the exact source file which is repeated of above format and has a lot of fields, I'm only retrieving one row.

SELECT *
 FROM OPENROWSET (BULK 'C:demo_jsonclaims.json', SINGLE_CLOB) as j
 CROSS APPLY OPENJSON(BulkColumn)

我搜索了一下，发现是因为多嵌套 json.使用下面的代码..

I've searched it and found out it is because of multi nested json. Used below code..

SELECT *
 FROM OPENROWSET (BULK 'C:demo_jsonclaims.json', SINGLE_CLOB) as j
 CROSS APPLY OPENJSON('['+BulkColumn+']')

但我收到错误消息:JSON 文本格式不正确.在位置 2760 处发现了意外字符{".

注意:我无法控制或无法编辑源文件 JSON我该怎么做才能确保 JSON 文件的格式正确或让我可以正确阅读它.

Note: I have no control or cant edit the source file JSON What can I do to make sure JSON file is in correct format or make it correct for me to read it.

源文件:声明

推荐答案

看来，您的输入文件包含行，这些行是有效的 JSON 对象.在这种情况下，一种可能的方法是使用 BULK INSERT 和适当的 ROWTERMINATOR 导入此文件:

It seems, that your input file has lines, which are valid JSON objects. One possible approach in this situation is to import this file using BULK INSERT and appropriate ROWTERMINATOR:

文本文件(claims.json):

Text file (claims.json):

声明:

CREATE TABLE #Data (
    BulkColumn nvarchar(max)
)
BULK INSERT #Data 
FROM 'C:demo_jsonclaims.json'
WITH (ROWTERMINATOR = '0x0A')

SELECT *
FROM #Data d
CROSS APPLY OPENJSON(d.BulkColumn) j

注意事项:

您可以尝试使用基本的字符串转换来构建有效的 JSON 数组，但逐行读取文件应该是您的第一选择:

You may try to use basic string transformations to build a valid JSON array, but reading the file line by line should be your first option:

SELECT *
FROM OPENROWSET (BULK 'C:demo_jsonclaims.json', SINGLE_CLOB) d
CROSS APPLY OPENJSON('[' + REPLACE(d.BulkColumn, '}' + CHAR(10) + '{', '},{') + ']') j
