DB::insert('insert into users (id, name) values (?, ?)', [1,'Dayle']); 基本插入操作 DB::table('users')->insert( ['email' =>'john@example.com','votes' =>0] ); DB::table('users')->insert([ ['email' =>'taylor@example.com','votes' =>0], ['email' =>'dayle@example....

$db -> select(DB::raw(‘name,age’)) -> get(); // 不解析字段,原样使用 注意:有多少个字段就有多少个参数(select方法),除了DB::raw之外。 (5)排序操作 DB::table(‘member’)->orderBy(‘age’,‘desc’)->get(); desc降序 asc 升序 默认升序 (6)分页操作 DB::table(‘member’)->limit(...
3、DB::raw()方法:可以在select()内部实现原生表达式,否则解析错误; //结合原生SQL 实现复杂查询 $users = DB::table('users')->select(DB::raw('COUNT(*) AS count, gender')) ->groupBy('gender') ->get(); // ->toSql(); 1. 2. 3. 4. 5. SQL 为: select COUNT(*) AS count, gende...
$query = DB::table('users')->select('name'); $users = $query->addSelect('age')->get(); 原生表达式 有时候你可能需要在查询中使用原生表达式,使用DB::raw方法可以创建原生表达式: $users = DB::table('users') ->select(DB::raw('count(*) as user_count, status')) ...
The query builder also provides an insert method for inserting records into the database table. The insert method accepts an array of column names and values to insert:1DB::table('users')->insert( 2 ['email' => 'john@example.com', 'votes' => 0] 3);...
$res = DB::select('SELECT * FROM tf_admin'); 运行查询的sql语句 print_r($res); echo 'hello laravel!'; } } 3.添加: 在类前面 use Illuminate\Support\Facades\DB; //引用数据库操作的命名空间 $res = DB::insert("insert into tf_aboutus (title,content) value('aaaaaa','assss')");/...
Raw MethodsInstead of using DB::raw, you may also use the following methods to insert a raw expression into various parts of your query.selectRawThe selectRaw method can be used in place of select(DB::raw(...)). This method accepts an optional array of bindings as its second argument:1...

在Laravel 9中,我们可以使用`DB::raw()`方法来使用Raw SQL语句。下面是一个使用Raw SQL语句执行INSERT查询的示例: DB::insert('INSERT INTO users (name, email) VALUES (?, ?)', ['John Doe', 'johndoe@example']); 上述代码使用原始的SQL语句将数据插入到名为"users"的表中。`DB::insert()`方法...
