基于swoole的mysql协程连接池,简单封装。
实现多个协程间共用同一个协程客户端
[1]:nowbe -> 新增数据返回insert_id
1、初完成
1、修复find()查询bug
1、将splqueque修改为channel
2、添加lock()
3、添加日志
4、表前缀
1、添加setDefer -> 设置是否返回结果(默认为true。部分操作,例如insert,update等,如果不需要返回返回结果,则可以设置为false)
2、使用go处理协程
3、完善日志功能
1、去掉日志功能,修改为在log文件打印错误信息和抛出异常
2、添加断线重连功能
3、添加instance()函数,如果有特殊需求扩展无法实现,又想共用连接池时,譬如事务处理,此时可以通过instance获取一个连接
4、添加put()函数,配合instance使用,使用完连接后,将连接put回连接池里
5、find()函数bug修复,返回一维数组
1、修复返回类型报警提示
2、修复where bug
1、where的or修复

$server为swoole服务器
如果有特殊需求扩展无法实现,又想共用连接池时,譬如事务处理,此时可以通过instance获取一个连接
例子:
<?php
$mysql = Db::init($this->MysqlPool)->instance();
配合instance使用,使用完连接后,将连接put回连接池里
例子:
<?php
$mysql = Db::init($this->MysqlPool)->instance();
$mysql->query('select * from `user_info`');
Db::init($this->MysqlPool)->put($mysql);
$tableName为表名 -- 字符串
$field为查询的字段名 -- 字符串
order by排序 -- 数组(一维数组或者二维数组)
例子: $order为一维数组时
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->order(['id'=>'desc'])
->select();
$order为二维数组时
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->order([['id'=>'desc'],['info'=>'asc']])
->select();
group by分组 -- 字符串
例子:
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->group('info')
->select();
### having($having)
用于配置group从分组中筛选数据 -- 字符串
例子:
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->group('info')
->having('count(info) > 5')
->select();
数据去重
$distinct为bool值
例子:
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->distinct(true)
->select();
加锁
例子:
<?php
//1、传入bool值
Db::init($this->MysqlPool)
->name('user_info')
->where(['id'=>1])
->lock(true)
->find();
//会自动在sql语句加上FOR UPDATE
//2、传入字符串
Db::init($this->MysqlPool)
->name('user_info')
->where(['id'=>1])
->lock('lock in share mode')
->find();
//特殊锁要求
获取sql语句
例子:
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->fetchSql()
->select();
$whereArray为数组
例子1:
<?php
//1、
$where = [
'id'=>'1'
];
//2、
$where = [
'id'=>['>',5]
];
//3、
$where = [
'username'=>['LIKE','%seth%']
];
//4、
$where = [
'id'=>['in',['1','5']]
];
//5、
$where = [
'note_info'=>['=','sethink','or']
];
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->where($where)
->select();
<?php
Db::init($this->MysqlPool)
->name('user_info')
->field('id,username')
->where(['id'=>['>',5]])
->where(['id'=>['<=',10]])
->select();
查询一条数据,返回一维数组
查询一条或多条数据,返回二维数组
插入单条数据
$data为一维数组
插入多条数据
$data为二维数组
更新数据
$data为一维数组
删除数据
执行sql语句 -- 字符串
例子:
<?php
$sql = 'select * from `user_info`';
Db::init($this->MysqlPool)->query($sql);
部分操作,例如insert,update等,如果不需要返回结果,则可以设置为false。
相对于$bool为true,sql执行后,由于主进程和协程间不需要再通信,可以立即往下执行程序
也可以全局设置,添加配置
$config = [
'setDefer' => true //设置是否返回结果,默认为true
];
$this->MysqlPool = new MysqlPool($config);
<?php
//此操作不会返回结果
Db::init($this->MysqlPool)
->name('user_info')
->setDefer(false)
->insert(['username'=>'sethink_5']);
