使用HR数据库进行练习之基本查询练习

这部分内容是从 https://www.w3resource.com/mysql-exercises/basic-simple-exercises/ 中找到练习，这里分享给大家，同时下面是自己做练习时写的一些笔记

要进行练习首先需要创建HR数据库，大家可以通过下面的语句进行来构建一个完整的HR数据库

Practice 1

编写一条SQL查询语句使用别名“First Name”和“Last Name”来显示employees表中的名字（first_name，last_name）

记住别名控制就行。

SELECT first_name 'First Name', last_name 'Last Name' FROM employees;

1	SELECT first_name 'First Name', last_name 'Last Name' FROM employees;

Practice 2

编写一条SQL查询语句从employees表中获取department ID，相同的department ID只显示一条

SELECT DISTINCT department_id FROM employees;

1	SELECT DISTINCT department_id FROM employees;

Practice 3

编写一条SQL查询语句，从employees表中获取employee的所有数据，并以first_name进行降序排列显示

SELECT * FROM employees ORDER BY first_name DESC;

1	SELECT * FROM employees ORDER BY first_name DESC;

Practice 4

编写一条SQL查询语句，获取所有employee的names(first_name, last_name), salary, PF（PF是salary的15%计算而来）

SELECT CONCAT(first_name, " ", last_name) names, salary, salary*0.15 PF FROM employees;

1	SELECT CONCAT(first_name, " ", last_name) names, salary, salary*0.15 PF FROM employees;

Practice 5

编写一条SQL查询语句，获取employee ID，name（first_name，last_name），salary，并以salary升序排列

ORDER BY关键字进行排序时，默认就是以升序排列的。

SELECT employee_id, CONCAT(first_name, " ", last_name) names, salary FROM employees ORDER BY salary;

1	SELECT employee_id, CONCAT(first_name, " ", last_name) names, salary FROM employees ORDER BY salary;

Practice 6

编写一条SQL查询语句来计算总共需要支付给employee的salary

使用sum()进行计算。

SELECT sum(salary) total_salary FROM employees;

1	SELECT sum(salary) total_salary FROM employees;

Practice 7

编写一条SQL查询语句来获取employees表中的最大和最小salary

使用max()和min()进行计算

SELECT MAX(salary) max_salary, MIN(salary) min_salary FROM employees;

1	SELECT MAX(salary) max_salary, MIN(salary) min_salary FROM employees;

Practice 8

编写一条SQL查询语句，从employees表中获取平均salary和employee的数量

SELECT AVG(salary) avg_salary, COUNT(*) num_employees FROM employees

1	SELECT AVG(salary) avg_salary, COUNT(*) num_employees FROM employees

Practice 9

编写一条SQL查询语句，获取为该公司工作的employee数量

SELECT COUNT(*) FROM employees;

1	SELECT COUNT(*) FROM employees;

Practice 10

编写一条SQL查询语句，从employees表中获取可用的jobs数量

SELECT COUNT(DISTINCT job_id) FROM employees;

1	SELECT COUNT(DISTINCT job_id) FROM employees;

Practice 11

编写一条SQL查询语句，从employees表中获取所有employee的first_name，使用大写显示

SELECT UPPER(first_name) upper_first_name FROM employees;

1	SELECT UPPER(first_name) upper_first_name FROM employees;

Practice 12

编写一条SQL查询语句，从employees表中获取first_name的钱三个字母

SELECT SUBSTRING(first_name, 1, 3) FROM employees;

1	SELECT SUBSTRING(first_name, 1, 3) FROM employees;

Practice 13

编写一条SQL查询语句计算171*214+625的值

SELECT 171*214+625 sum;

1	SELECT 171*214+625 sum;

Practice 14

编写一条SQL查询语句，从employees表中获取名字（例如 Ellen Abel， Sundar Ande）

使用CONCAT()字符串函数。

SELECT CONCAT(first_name, " ", last_name) name FROM employees;

1	SELECT CONCAT(first_name, " ", last_name) name FROM employees;

Practice 15

编写一条SQL查询语句，从employees表中获取first_name，并去掉first_name两边的空格

使用TRIM()字符串函数。

SELECT (first_name) FROM employees;

1	SELECT (first_name) FROM employees;

Practice 16

编写一条SQL查询语句，从employees表中获取names（first_name，last_name）的长度

使用LENGTH()字符串函数。

SELECT LENGTH(first_name) first_name_length, LENGTH(last_name) last_name_length FROM employees;

1	SELECT LENGTH(first_name) first_name_length, LENGTH(last_name) last_name_length FROM employees;

Practice 17

编写一条SQL查询语句，检查employees表中first_name列是否有包含数字的行

使用REGEXP

SELECT first_name FROM employees WHERE first_name REGEXP '[0-9]';

1	SELECT first_name FROM employees WHERE first_name REGEXP '[0-9]';

Practice 18

编写一条SQL查询语句，选择employees表中的前十条记录

SELECT * FROM employees LIMIT 10;

1	SELECT * FROM employees LIMIT 10;

Practice 19

编写一条SQL查询语句，获取每个employee的月薪，精确到小数点后两位。

SELECT first_name, last_name, round(salary/12,2) 'Monthly Salary' FROM employees;

1	SELECT first_name, last_name, round(salary/12,2) 'Monthly Salary' FROM employees;
