SqlServer 操作 Json（sqlserver 操作日志）

SqlServer 操作 Json（sqlserver 操作日志）

Sql Server 从 2016 开始支持了一些 json 操作，最近的项目里也是好多地方直接用字段直接存成了 json ，需要了解一下怎么在 Sql Server 中操作 JSON.

JSON支持适用于 SqlServer 2016 及以上版本 和 Azure SQL Database。

SqlServer 中内置了一些 JSON 相关的方法：
可以判断一段字符串是否是标准的 json（ISJSON）
可以直接查询数据成 json 格式(FOR JSON PATH) 类似于之前的查询一个 xml (FOR XML PATH)，
查询一个 json 对象的值(JSON_VALUE)
查询一个 json 数组值
更新一段JSON的内容，修改 JSON 对象里的属性值，删除 JSON 对象里的某一个属性，增加属性
解析一段 json 内容 (OPENJSON)

JSON 操作

JSON 存储

数据库里 JSON 存储一般用 NVARCHAR(MAX) 类型来保存，如果一定是 JSON 形式的数据可以设置一个约束，可以通过 ISJSON 来给字段加约束，详情参考

JSON 属性加索引

要给 JSON 对象的某个属性加字段时，需要增加一个虚拟的列，然后在这个列中建立一个索引。

1 ALTER TABLE Sales.SalesOrderHeader
2 ADD vCustomerName AS JSON_VALUE(Info,''$.Customer.Name'')
3 
4 CREATE INDEX idx_soh_json_CustomerName
5 ON Sales.SalesOrderHeader(vCustomerName)

 

JSON 基本操作

{
    "name": "小明",
    "info": {
        "address": {
            "province": "河南省",
            "city": "郑州市",
            "district": "郑东新区"
        },
        "hobbies": [
            "篮球",
            "足球",
            "乒乓球"
        ]
    }
}
 1 -- 查询某一属性值
 2 SET @name = JSON_VALUE(@jsonInfo, ''$.name'');
 3 SET @city = JSON_VALUE(@jsonInfo, ''$.info.address.city'');
 4 
 5 -- 查询数组
 6 SET @hobbies = JSON_QUERY(@jsonInfo, ''$.info.hobbies'');
 7 
 8 -- 增加属性 tempProp
 9 
10 SET @jsonInfo = JSON_MODIFY(@jsonInfo, ''tempProp'', 1);
11 
12 -- 删除属性 tempProp
13 SET @jsonInfo = JSON_MODIFY(@jsonInfo, ''tempProp'', null);

如图是两张表 一张key表和value表，通过链接查询查询出来的，我如何在代码中循环取值出来，，，问题是他是两张表啊。。。。。

登录后复制

这样，可以方便地构造出自己的连接字符串。

同时这里用到几个比较有用的有关数据库服务器及数据库结构的函数。比如查询局域网中所有数据库实例，获取目标实例所有数据库，获取指定数据库的所有表，获取指定表所有行：

2、错误原因

        在Java连接Sql Server数据库，做查询语句时，利用静态常量编写sql语句

 

private static final String QUERY_STUDENT = "";

        sql语句没有加进去，并且student表中存在索引，导致报错

 

3、解决办法

      将sql语句插入到静态常量里，重新运行测试用例

2、错误原因

 

      本地连接Sql Server数据库，未打开telnet协议

 

3、解决办法

（1）打开开始输入“cmd”，在命令窗口输入：telnet 127.0.0.1

（2）如果提示“不是内部命令”，需要设置telnet协议‘

（3）控制面板--->程序--->打开或关闭Windows功能，将telnet客户端和服务端都勾选上

（4）计算机--->管理--->服务--->开启telnet服务
