| 实例如下： 创建数据表： mysql> CREATE TABLE Employee( -> id int, -> first_name VARCHAR(15), -> last_name VARCHAR(15) -> );Query OK, 0 rows affected (0.03 sec)
向表中插入数据： mysql> insert into Employee(id,first_name, last_name)values (1,'Jason','Martin');Query OK, 1 row affected (0.00 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(2,'Alison','Mathews');Query OK, 1 row affected (0.00 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(3,'James','Smith');Query OK, 1 row affected (0.00 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(4,'Celia','Rice');Query OK, 1 row affected (0.00 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(5,'Robert','Black');Query OK, 1 row affected (0.00 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(6,'Linda', 'Green');Query OK, 1 row affected (0.01 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(7,'David','Larry');Query OK, 1 row affected (0.02 sec)mysql>mysql> insert into Employee(id,first_name, last_name)values(8,'James','Cat');Query OK, 1 row affected (0.00 sec)
select语句中使用函数 mysql> SELECT concat(First_Name, " ",Last_Name) AS Name FROM Employee;+----------------+| Name |+----------------+| Jason Martin || Alison Mathews || James Smith || Celia Rice || Robert Black || Linda Green || David Larry || James Cat |+----------------+8 rows in set (0.00 sec)
