SELECT语句
SELECT *
; FROM employee
SELECT *
; FROM employee
; ORDER BY emp_lname ASC
SELECT *
; FROM employee
; ORDER BY emp_lname DESC
SELECT emp_lname, dept_id, birth_date
; FROM employee
SELECT *
; FROM employee
; WHERE emp_fname='John'
(一定使用单引号)
SELECT emp_fname, emp_lname, birth_date
; FROM employee
; WHERE emp_fname = 'John'
; ORDER BY birth_date
SELECT emp_lname, birth_date
; FROM employee
; WHERE birth_date < 'March 3, 1964'
(=、<、>、<=、>=、<>，加上AND与OR)
SELECT emp_lname, emp_fname
; FROM employee
; WHERE emp_lname LIKE 'br%'
(%、_)
SELECT emp_lname, emp_fname
; FROM employee
; WHERE SOUNDEX( emp_lname ) = SOUNDEX( 'Brown' )
(找出英文中发音相同的记录，中文下用处不大)
SELECT emp_lname, birth_date
; FROM employee
; WHERE birth_date BETWEEN '
1965-1-1' AND '
1965-3-31'
SELECT emp_lname, emp_id
; FROM employee

连接表
SELECT *
; FROM sales_order, employee
; WHERE sales_order.sales_rep = employee.emp_id
SELECT E.emp_lname, S.id, S.order_date
; FROM sales_order as S, employee as E
; WHERE S.sales_rep = E.emp_id
; ORDER BY E.emp_lname
连接两表的快捷键：KEY JOIN及NATURAL JOIN，最好用WHERE.
SELECT emp_lname, id, order_date
; FROM sales_order
; KEY JOIN employee
(主键与外部键对应的地方，就可以用KEY JOIN)
SELECT company_name,
; CAST( SUM(sales_order_items.quantity * product.unit_price) AS INTEGER) AS value
; FROM customer
; KEY JOIN sales_order
; KEY JOIN sales_order_items
; KEY JOIN product
; GROUP BY company_name
SELECT emp_lname, dept_name
; FROM employee
; NATURAL JOIN department
(找出两表间有相同的字段名，进行连结)
集合
SELECT count( * )
; FROM employee
SELECTcount( * ),
; min( birth_date ),
; max( birth_date )
; FROM employee
(MIN, MAX, COUNT, AVG, SUM, LIST，作为单独的一列选出)
SELECT sales_rep, count( * )
; FROM sales_order
; GROUP BY sales_rep
(在使用GROUP BY时，对于GROUP BY指定的字段，其每一个不同的值都会组成一行)
SELECT sales_rep, count( * )
; FROM; sales_order
; KEY JOIN employee
; GROUP BY sales_rep
; HAVING count( * ) > 55

视图
CREATE VIEW emp_dept AS

SELECT *

(视图能自动更新状态)
DROP VIEW emp_dept
CREATE VIEW emp_dept(FirstName, LastName, Department) AS

(创建视图不能使用ORDEY BY，但使用视图可以使用)
SELECT LastName, dept_head_id
; FROM emp_dept, department
; WHERE emp_dept.Department = department.dept_name
(将视图与其他表进行进一步的连结)
