3.删除区间数据
    $code=Db::table("user")->where("id>0 and id<5")->delete();
Copy after login
Copy after login

6. Transaction mechanism

1.mysql transaction

The engine that requires data must be InnoDB
Key point: execute the statement on the data table to be operated: ALTER TABLE user ENGINE=INNODB;

2. Use

1. Automatically control transactions

Db::transaction(function(){    // 删除一条数据    Db::table("user")->delete(11);    Db::table("user")->deletes(40);});
Copy after login
Copy after login

2. Manually control transactions

// 手动控制事务
    // 开启事务
    Db::startTrans();    try{        // 删除数据
        $a=Db::table("user")->delete(11);        // 判断是否删除成功
        if(!$a){            throw new  \Exception("删除11没有成功");
        }        // 删除不存在的数据
        $b=Db::table("user")->delete(12);        if(!$b){            throw new  \Exception("删除12没有成功");
        }        // 执行提交操作
        Db::commit();`这里写代码片`        echo "成功";
    }catch(\Exception $e){        // 回滚事务
        echo "失败";
        Db::rollback();
        dump($e->getmessage());
    }
Copy after login

    // 开启事务
    Db::startTrans();    // 删除数据
    $a=Db::table("user")->delete(1);    $b=Db::table("user")->delete(2);    // 判断条件
    if($a && $b){        // 提交事务
        Db::commit();
    }else{
        Db::rollback();
    }

        $data=Db::table("user")->field("count(*) as tot")->select();
        $data=Db::table("user")->field(["count(*)"=>"tot"])->select();
    //排除字段
        $data=Db::table("user")->field("name,pass",true)->select();
        $data=Db::table("user")->field(["name","pass"],true)->select();
9.Page实现分页效果
    $data=Db::table("user")->page(3,5)->select();
    $data=Db::table("user")->page("3,5")->select();
10.分组聚合
    $data=Db::table("user")->field("pass,count(*) tot")->group("pass")->select();
11.having过滤
    // 只能结合分组使用
        $data=Db::table("user")->field("pass,count(*) tot")->having("tot >=4")->group("pass")->select();
12.多表查询
    // 内敛实现数据库连接
        $data=Db::query("select product.*,fenlei.name tname from fenlei,product where product.cid=fenlei.id");
        $data=Db::table("product")->field("product.*,fenlei.name tname")->join("fenlei","product.cid=fenlei.id")->select();
        // 右链接
        $data=Db::table("product")->field("product.*,fenlei.name tname")->join("fenlei","product.cid=fenlei.id",&#39;right&#39;)->select();
        // 左链接
        $data=Db::table("product")->field("product.*,fenlei.name tname")->join("fenlei","product.cid=fenlei.id",&#39;left&#39;)->select();
13.别名使用-给表起别名
    $data=Db::table("product")->alias(&#39;p&#39;)->field("p.*,f.name fname")->join("fenlei f","p.cid=f.id",&#39;left&#39;)->select();
14.union集合
    $data=Db::field("name")->table("user")->union("select name from product")->select();
15.参数绑定bind为了防止sql注入
    //自动轻微防止sql注入
    $data=Db::table("user")->where("id",$id)->delete(); 
    //不防注入 建议不要使用原生的sql语句
    $data=Db::execute("delete from user where id=$id");
    //防注入
    $data=Db::table("user")->where("id",":id")->bind([&#39;id&#39;=>[$id,\PDO::PARAM_INT]])->delete();
16.统计数据
        $data=Db::table("user")->max("age");
        $data=Db::table("user")->min("age");
        $data=Db::table("user")->avg("age");
        $data=Db::table("user")->sum("age");
        $data=Db::table("user")->count();
17.视图查询(多表查询)
        $data=Db::view("goods","id,name,price")->view("type","name","type.id=goods.cid")->select();
        // 左连接
        $data=Db::view("goods","id,name,price")->view("type","name","type.id=goods.cid","right")->select();
        // 右连接
        $data=Db::view("goods","id,name,price")->view("type","name","type.id=goods.cid","left")->select();
Copy after login
Copy after login

2.插入操作

1.插入单条数据
    // 数组中的字段名必须和数据库中字段名一致
        $data=[
            &#39;name&#39;=>&#39;张三&#39;,
            &#39;pass&#39;=>&#39;123&#39;,
            &#39;age&#39;=>18
        ];
        // 返回值:影响行数
        $code=Db::table("user")->insert($data);
        $code=db("user")->insert($data);
2.插入多条数据
    $data=[
        [
            &#39;name&#39;=>&#39;张三1&#39;,
            &#39;pass&#39;=>&#39;123&#39;,
            &#39;age&#39;=>18
        ],
        [
            &#39;name&#39;=>&#39;张三2&#39;,
            &#39;pass&#39;=>&#39;123&#39;,
            &#39;age&#39;=>18
        ]
    ];
    //返回值:影响行数 
    $code=Db::table("user")->insertAll($data);
    $code=db("user")->insertAll($data);
3.获取最后一次插入的id
    $data=[
        &#39;name&#39;=>&#39;张三1&#39;,
        &#39;pass&#39;=>&#39;123&#39;,
        &#39;age&#39;=>18
    ];
    $code=Db::table("user")->insertGetId($data); 
    $code=db("user")->insertGetId($data);
Copy after login
Copy after login

3.更新数据

1.修改数据
    $code=Db::table("user")->where("id",">",5)->update(["age"=>111,"pass"=>&#39;111&#39;]);
    $code=Db::table("user")->update(["id"=>5,"age"=>60]);
    code=Db::table("user")->where("id",5)->setField("age",111);
2.设置自增
    $code=Db::table("user")->where("id",6)->setInc("age");
3.设置自减
    $code=Db::table("user")->where("id",7)->setDec("age");
    $code=Db::table("user")->where("id",5)->setDec("age",3);
Copy after login
Copy after login

4.删除数据

1.删除一条数据
    $code=Db::table("user")->where("id",6)->delete();
    $code=Db::table("user")->delete(7);
2.删除多条数据
    $code=Db::table("user")->where("id in(1,2)")->delete();
    $code=Db::table("user")->delete([2,3]);
3.删除区间数据
    $code=Db::table("user")->where("id>0 and id<5")->delete();
Copy after login
Copy after login

六、事务机制

1.mysql事务

要求数据的引擎必须是InnoDB
重点:对要操作的数据表执行语句:ALTER TABLE user ENGINE=INNODB;

2.使用

1. 自动控制事务

Db::transaction(function(){    // 删除一条数据    Db::table("user")->delete(11);    Db::table("user")->deletes(40);});
Copy after login
Copy after login

2. 手动控制事务

// 手动控制事务
    // 开启事务
    Db::startTrans();    try{        // 删除数据
        $a=Db::table("user")->delete(11);        // 判断是否删除成功
        if(!$a){            throw new  \Exception("删除11没有成功");
        }        // 删除不存在的数据
        $b=Db::table("user")->delete(12);        if(!$b){            throw new  \Exception("删除12没有成功");
        }        // 执行提交操作
        Db::commit();`这里写代码片`        echo "成功";
    }catch(\Exception $e){        // 回滚事务
        echo "失败";
        Db::rollback();
        dump($e->getmessage());
    }    // 开启事务
    Db::startTrans();    // 删除数据
    $a=Db::table("user")->delete(1);    $b=Db::table("user")->delete(2);    // 判断条件
    if($a && $b){        // 提交事务
        Db::commit();
    }else{
        Db::rollback();
    }
Copy after login
