题目 已知下列员工关系表EMPLOYEES 员工号 部门 工资 04501 财务 3000 05601 市场 4000 03020 研发 3500 对该表的工资属性和完整性约束为：2000≤工资≤ 操作1：INSERT INTO EMPLOYEES VALUES('03650','研发','4600'); 操作2：UPDATE EMPLOYEES SET 工资=工资*1.2 WHERE 部门='市场 ' OR 部门='研发'; 事务T执行完毕后，关系表EMPLOYEES的数据是（） A、 员工号 部门 工资 04501 财务 3000 05601 市场 4000 03020 研发 3500 03650
这个问题很多时候是没有为该表建立触发器导致的，或者是sequence没建立，或者是trigger没建立。
1、用户 已经存在了employees、employees_read用户，新建一个写用户 mysql> CREATE USER 'employees_write'@'%' IDENTIFIED BY ; Query OK, 0 rows affected (0.01 sec) （2）只读角色 mysql> grant select on employees.* to employees_r; Query | % | employees | N | | % | employees_r | % | employees_read `employees` TO `employees_read`@`%` | | GRANT `employees_r`@`%` TO `employees_read`@`%` `employees`@`%` | | GRANT `employees_admin`@`%` TO `employees`@`%` | +----
`id` AS `id`,`employees`.`name` AS `name`,`employees`.`age` AS `age`,`employees`. `position` AS `position`,`employees`.`hire_time` AS `hire_time` from `employees` where (`employees`. `name` > 'a') order by `employees`. `id` AS `id`,`employees`.`name` AS `name`,`employees`.`age` AS `age`,`employees`. `position` AS `position`,`employees`.`hire_time` AS `hire_time` from `employees` where (`employees`.
`employees_1`.`emp_no` AS `emp_no`,`employees`.`employees_1`. `hire_date` AS `hire_date` from `employees`.`employees_1` where (`employees`.`employees_1`. `employees_1`.`emp_no` AS `emp_no`,`employees`.`employees_1`. `hire_date` AS `hire_date` from `employees`.`employees_1` where (`employees`.`employees_1`. `employees_1`.`emp_no` AS `emp_no`,`employees`.`employees_1`.
这里测试基于 employees 表创建 employees_ptosc 表： mysql root@localhost:employees> create table employees_ptosc `employees_ptosc`... `employees`.`employees_ptosc` was not altered. `employees` FOR EACH ROW DELETE IGNORE FROM `employees`.`_employees_new` WHERE `employees`. `employees` 200 Query RENAME TABLE `employees`.`_employees_new` TO `employees`. `employees` TO `employees`.`_employees_old`, `employees`.`_employees_new` TO `employees`.

题目 有一个员工employees表简况如下: 请你查找employees里入职员工时间排名倒数第三的员工所有信息，以上例子输出如下: 2 表结构 drop table if exists ` employees` ; CREATE TABLE `employees` ( `emp_no` int(11) NOT NULL, `birth_date` date NOT NULL, `first_name VALUES(10001,'1953-09-02','Georgi','Facello','M','1986-06-26'); INSERT INTO employees VALUES(10002,' employees VALUES(10007,'1957-05-23','Tzvetan','Zielinski','F','1989-02-10'); INSERT INTO employees VALUES -01-22'); 答案 select * from employees where hire_date = ( select distinct hire_date from employees
浏览器中打开链接：http://www.itsoku.com/article/209 mysql中执行里面的javacode2018_employees库部分的脚本。 成功创建javacode2018_employees库及5张表，如下： 表名 描述 departments 部门表 employees 员工信息表 jobs 职位信息表 locations 位置表（部门表中会用到 ①的结果*/ SELECT * FROM employees a WHERE a.salary > (SELECT salary FROM employees (salary) FROM employees; /*③方式1：查询员工信息*/ SELECT * FROM employees a WHERE a.employee_id = (SELECT min( FROM employees); /*方式2*/ SELECT * FROM employees a WHERE (a.employee_id, a.salary) = (SELECT
有一个员工employees表简况如下: 0BFB4D140D9C3E92AF681D9F9CB92D55 请你查找employees里最晚入职员工的所有信息，以上例子输出如下: D2ABA1E2F5834850B16146F168AC5476 对应SQL语句: DDL drop table if exists `employees` ; CREATE TABLE `employees` ( `emp_no` int(11) NOT NULL VALUES(10001,'1953-09-02','Georgi','Facello','M','1986-06-26'); INSERT INTO employees VALUES(10002,' employees VALUES(10007,'1957-05-23','Tzvetan','Zielinski','F','1989-02-10'); INSERT INTO employees VALUES -01-22'); 参考答案: SELECT * FROM employees where hire_date = (SELECT hire_date from employees order by

题目：有一个员工employees表简况如下: 0BFB4D140D9C3E92AF681D9F9CB92D55 (1) 结果：请你查找employees里入职员工时间排名倒数第三的员工所有信息，以上例子输出如下 : 2A26AB183839E3A01C933AE5A75B6D2F 数据表：表结构 drop table if exists `employees` ; CREATE TABLE `employees employees VALUES(10007,'1957-05-23','Tzvetan','Zielinski','F','1989-02-10'); INSERT INTO employees VALUES select * from employees where hire_date = (select distinct hire_date from employees order by hire_date select * from employees where hire_date = (select hire_date from employees group by hire_date order

表及employees_mask视图。 /employees/employees.csv [root@ip-172-31-16-68 datamasking]# （可左右滑动） [eoosedypu9.jpeg] 4.验证employees 通过上图可以看出Group A可以访问视图employees_unmasked里未经遮蔽的数据，但是不能直接访问表employees，当然也不能访问底层文件。 而Group B只能访问employees_masked视图里的数据，这个是有敏感数据被屏蔽了的，因为Sentry的控制，他没权限直接访问employees表或者通过HDFS文件去获取真实的被屏蔽的值。 和employees_masked视图数据 Hive引擎查询employees_masked脱敏视图数据 [clm7jku5l5.jpeg] Hive引擎查询employees_unmasked未脱敏视图
CASCADE，表明此表的emp_no引用的是employees表的emp_no，同时ON DELETE CASCADE指明一旦删除employees的某emp_no的记录，相应也会在这个表中删除这条记录 02 employees示例库 看这个概念前，先介绍一个实例库。 导入MySql的employees库，下载地址： https://dev.mysql.com/doc/employee/en/employees-installation.html 解压缩后，找到 employees.sql 没有添加组合索引前的查询： SELECT * FROM employees.employees WHERE first_name='Eric' AND last_name='Anido' 耗时：0.609s 添加组合索引： ALTER TABLE employees.employees ADD INDEX `first_name_last_name4` (first_name, last_name(4))
