有一個各個部門的領(lǐng)導表dept_manager簡況如下:
請你查找各個部門當前領(lǐng)導的薪水詳情以及其對應部門編號dept_no，輸出結(jié)果以salaries.emp_no升序排序，并且請注意輸出結(jié)果里面dept_no列是最后一列，以上例子輸出如下:
表結(jié)構(gòu)
drop table if exists `salaries` ;drop table if exists `dept_manager` ;CREATE TABLE `salaries` (`emp_no` int(11) NOT NULL,`salary` int(11) NOT NULL,`from_date` date NOT NULL,`to_date` date NOT NULL,PRIMARY KEY (`emp_no`,`from_date`));CREATE TABLE `dept_manager` (`dept_no` char(4) NOT NULL,`emp_no` int(11) NOT NULL,`to_date` date NOT NULL,PRIMARY KEY (`emp_no`,`dept_no`));
