It is written in JavaScript,crud for mysql.You can also use transactions very easily.node
mysqls 一款专为node.js生成sql语句的插件,链式调用,使用灵活。支持生成sql语法,也支持生成语法以后直接调用,支持事物等特性。
API参考很流行的ThinkPHP模型API。mysql
npm install mysqls --save-dev
- init: sql初始化API
- exec: 执行sql语句
- sql: 链式调用生成sql语句,支持生成后直接执行sql语句
- transaction: 执行事务API
//import方式 import { init, exec, sql, transaction } from 'mysqls' //require方式 let { init, exec, sql, transaction } = require('mysqls')
// 可在项目的启动时初始化配置 init({ host: 'localhost', user: 'root', password:'123456', database: 'test', port: 3306, })
- ispool: 是否以链接池的方式初始化 (default:true)
- host: host地址 (default:'127.0.0.1')
- user: 用户名 (default:'root')
- password: 数据库密码 (default:'root')
- database: 使用的数据库 (default:'test')
- port: 端口 (default:'3306')
- waitConnection: 是否等待连接(链接池时使用) (default:true)
- connectionLimit: 链接池大小 (default:10)
- queueLimit: 排队限制 (default:0)
sql .table('node_table') .field('id,name') .where({id:1}) .select() // result SELECT id,name FROM node_table WHERE id=1
const sqlstr = sql .table('node_table') .field('id,name') .where({id:1}) .select(); const result = await exec(sqlstr);
const result = sql .table('node_table') .field('id,name') .where({id:1}) .select(true) .exec();
//使用 exec 函数 exec(sql.table('web_pages').where({id:147}).select()) .then(res=>{ console.log(res) }).catch(err=>{ console.log(err) }) // 使用 exec 方法 sql.table('web_pages').where({id:147}).select(true).exec() .then(res=>{ console.log(res) }).catch(err=>{ console.log(err) })
//使用 exec 函数 const result = await exec(sql.table('web_pages').where({id:147}).select()) // 使用 exec 方法 const result = await sql.table('web_pages').where({id:147}).select(true).exec()
const tranSqlArr = [ sql.table('table1').data({number:'number-5'}).update(), sql.table('table2').data({number:'number+5'}).update() ] const result = await transaction(tranSqlArr)
查询web
sql .table('node_table') .field('id,name') .where({id:1}) .select() SELECT id,name FROM node_table WHERE id=1
插入sql
sql .table('node_table') .data({name:'zane',email:'752636052@qq.com'}) .insert() INSERT INTO node_table (name,email) VALUES (`zane`,`752636052@qq.com`)
更新数据库
sql .table('node_table') .data({name:'zane',email:'752636052@qq.com'}) .update() UPDATE node_table SET name=`zane`,email=`752636052@qq.com`
删除npm
sql .table('node_table') .where({name:'zane'}) .delet(); DELETE FROM node_table WHERE name=`zane`
//参数json多字段 sql .table('node_table') .where({id:1,name:'zane'}) .select() SELECT * FROM node_table WHERE id=1 AND name=`zane` //参数数组 let data=[ {id:1,name:'zhangsan',_type:'or'}, {sex:1,number:3} ] sql.table('node_table').where(data).select() SELECT * FROM node_table WHERE (id=1 OR name=`zhangsan` ) AND (sex=1 AND number=3 ) //多字段链接方式 let data=[ {id:1,name:'zhangsan',_type:'or',_nexttype:'or'}, {sex:1,number:3,_type:'and'} ] sql.table('node_table').where(data).select() SELECT * FROM node_table WHERE (id=1 OR name=`zhangsan`) OR (sex=1 AND number=3) //表达式查询 let data={ id:{eq:100,egt:10,_type:'or'}, name:'zhangshan' } sql.table('node_table').where(data).select() SELECT * FROM node_table WHERE ((id=100) OR (id>=10)) AND name=`zhangshan` //混合查询 let data=[{ id:{eq:100,egt:10,_type:'or'}, name:'zhangshan', _nexttype:'or' },{ status:1, name:{like:'%zane%'} }] sql.table('node_table').where(data).select() SELECT * FROM node_table WHERE (((id=100) OR (id>=10)) AND name=`zhangshan`) OR (status=1 AND ((name LIKE `%zane%`))) //UNION , UNION ALL 组合使用 sql .union('SELECT * FROM think_user_1',true) .union('SELECT * FROM think_user_2',true) .union(['SELECT * FROM think_user_3','SELECT name FROM think_user_4']) .union('SELECT * FROM think_user_5',true) .select() 获得 (SELECT * FROM think_user_1) UNION ALL (SELECT * FROM think_user_2) UNION ALL (SELECT * FROM think_user_3) UNION (SELECT name FROM think_user_4) UNION (SELECT * FROM think_user_5)
