配置里用json怎么改为sql

发布时间: 2022-09-03 19:16:08

㈠ json格式的数组，怎么转成其他格式数据库比如xls csv sql

利用代码将其转化，不同语言不同操作也

㈡ 如何用C#将序列化为json的字符串导入到sql server中数据库

将序列化为json的字符串tostring，然后，直接当成字符存入数据库即可。

㈢ 如何把多种数据转为json存储到sql

这个 一般就是 一个拼接字符串的问题吧你把 String aaa ="aaa"; int bbb = 101;就可以这样拼接啊 StringBuffer sb sb。apand（“｛”）；sb。apand（“aaa:"+""+aaa);sb。apand（“,bbb:"+""+bbb);sb。apand（“｝”）；封装成一个字符串 就可以 存了 json只是一种数据格式 本质 可以理解为 字符串 而已 可以用字符串保存到数据库 很简的啊

㈣ java将json数据解析为sql语句

importjava.util.Iterator;
importjava.util.Set;
importjava.util.Map.Entry;

importcom.google.gson.JsonArray;
importcom.google.gson.JsonElement;
importcom.google.gson.JsonObject;
importcom.google.gson.JsonParser;

publicclassSql
{
	publicstaticStringparseSQL(Stringjson)
	{
		JsonParserparser=newJsonParser();
		JsonObjectobj=(JsonObject)parser.parse(json);;
		Stringtable=obj.get("table").getAsString();
		Stringop_type=obj.get("op_type").getAsString();
		Stringsql="";
		if("I".equals(op_type))
		{
			sql+="INSERTINTO"+table+"(";
			JsonObjectafter=(JsonObject)obj.get("after");
			Set<Entry<String,JsonElement>>entry=after.entrySet();
			Iterator<Entry<String,JsonElement>>it=entry.iterator();
			Stringvs="values(";
			while(it.hasNext())
			{
				Entry<String,JsonElement>elem=it.next();
				Stringkey=elem.getKey();
				Stringval=elem.getValue().toString();
				sql+=key+",";
				vs+=val+",";
			}
			sql=sql.replaceAll(",\s*$","");
			vs=vs.replaceAll(",\s*$","");
			sql+=")"+vs+")";
		}
		elseif("U".equals(op_type))
		{
			sql+="UPDATE"+table+"SET";
			JsonObjectafter=(JsonObject)obj.get("after");
			Set<Entry<String,JsonElement>>entry=after.entrySet();
			Iterator<Entry<String,JsonElement>>it=entry.iterator();
			while(it.hasNext())
			{
				Entry<String,JsonElement>elem=it.next();
				Stringkey=elem.getKey();
				Stringval=elem.getValue().toString();
				sql+=key+"="+val+",";
			}
			sql=sql.replaceAll(",\s*$","");
			sql+="WHERE";
			after=(JsonObject)obj.get("before");
			entry=after.entrySet();
			it=entry.iterator();
			while(it.hasNext())
			{
				Entry<String,JsonElement>elem=it.next();
				Stringkey=elem.getKey();
				Stringval=elem.getValue().toString();
				sql+=key+"="+val+"AND";
			}
			sql=sql.replaceAll("\s*AND\s*$","");
		}
		elseif("D".equals(op_type))
		{
			sql+="DELETEFROM"+table+"WHERE";
			JsonObjectafter=(JsonObject)obj.get("before");
			Set<Entry<String,JsonElement>>entry=after.entrySet();
			Iterator<Entry<String,JsonElement>>it=entry.iterator();
			while(it.hasNext())
			{
				Entry<String,JsonElement>elem=it.next();
				Stringkey=elem.getKey();
				Stringval=elem.getValue().toString();
				sql+=key+"="+val+"AND";
			}
			sql=sql.replaceAll("\s*AND\s*$","");
		}
		returnsql;
	}

	publicstaticvoidmain(String[]args)
	{

㈤ 如何将拼凑的json串存入sqlserver中

先检查数据库中保存这个数据的字段的数据类型是否设置有误，这种大量字符的字段，数据类型可以使用text或者varchar(max),如果数据库的字段设置没有问题，请检查存储前的代码，是否有字符串截断操作。

㈥ 如何将从接口取到的json数据存入mysql数据库

mysql数据库建立表，存储json字段用text类型
然后从接口中获取JSON数据，转成STRING格式，直接插入到这个字段就可以了。

㈦ 如何将网上json数据库解析到本地的sql数据库中啊

取得数据最开始是json字符串->转化为json数据->保存到数据库

json数据知道的话，很简单了

㈧ java将json格式转换嫒虽ysql的java脚本，有没有

执行环境
需要以下类库支持
commons-lang 2.5
commons-beanutils 1.8.0
commons-collections 3.2.1
commons-logging 1.1.1
ezmorph 1.0.6
4.功能示例
这里通过JUnit-Case例子给出代码示例

复制代码代码如下:

package com.mai.json;

import static org.junit.Assert.assertEquals;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import net.sf.ezmorph.Morpher;
import net.sf.ezmorph.MorpherRegistry;
import net.sf.ezmorph.bean.BeanMorpher;
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
import net.sf.json.util.JSONUtils;
import org.apache.commons.beanutils.PropertyUtils;
import org.junit.Test;
public class JsonLibTest {
/*
* 普通类型、List、Collection等都是用JSONArray解析
*
* Map、自定义类型是用JSONObject解析
* 可以将Map理解成一个对象，里面的key/value对可以理解成对象的属性/属性值
* 即{key1:value1,key2,value2......}
*
* 1.JSONObject是一个name:values集合，通过它的get(key)方法取得的是key后对应的value部分(字符串)
* 通过它的getJSONObject(key)可以取到一个JSONObject，--> 转换成map,
* 通过它的getJSONArray(key) 可以取到一个JSONArray ，
*
*

㈨ 如何获取从his系统json的数据解析为xml插入sql用c#实现

序列化只是将数据序列化为完整的准确无误的json格式的数据！
解析指的就是将你上面的json数据一一从json格式中分解出来，的到字符串格式的便于封装bean对像
建立一对多的对象
将value setter给你的bean对象！
最后将bean存数据库

㈩ 如何解析JSON数组到SQL表

例如：

源JSON数据：

{
"item1":{
"title":"2",
"value":null,
"visible":true,
"name":"item1",
"enabled":true,
"readonly":false,
"id":"f1f46ce6-9d0b-4eaf-88b7-d35b23a4d2e4"
},
"item2":{
"title":null,
"value":null
"visible":true,
"name":"item2",
"enabled":true,
"readonly":false,
"id":"da2b8a02-cfbd-4de8-8a33-74e2a484475a"
},
"item3":{
"title":"",
"value":null,
"visible":true,
"name":"item3",
"enabled":true,
"readonly":false,
"id":"57ee45d6-41d7-45c2-b022-13220e31d2d2"
}}

SQL查询

SELECT[Key].[key]AS[ItemName],[Value].*FROMOPENJSON(@json,'$')AS[Key]CROSSAPPLYOPENJSON([Key].value)
WITH(
TitleVARCHAR(100)'$.title',
ValueVARCHAR(100)'$.value',
VisibleVARCHAR(100)'$.visible',
NameVARCHAR(100)'$.name',
EnabledVARCHAR(100)'$.enabled',
ReadOnlyVARCHAR(100)'$.readonly',
IdVARCHAR(500)'$.id'
)AS[Value]
