mysql create创建表、insert into插入数据、select查询数据实例

mysql创建表的sql代码如下：

CREATE TABLE Employee(
     id            int,
     first_name    VARCHAR(15),
     last_name     VARCHAR(15),
     start_date    DATE,
     end_date      DATE,
     salary        FLOAT(8,2),
     city          VARCHAR(10),
     description   VARCHAR(15)
);

或者是

CREATE TABLE IF NOT EXISTS Employee(
     id            int,
     first_name    VARCHAR(15),
     last_name     VARCHAR(15),
     start_date    DATE,
     end_date      DATE,
     salary        FLOAT(8,2),
     city          VARCHAR(10),
     description   VARCHAR(15)
);

mysql insert into插入数据代码如下：

insert into Employee(id,first_name,last_name,start_date,end_Date,salary,City,Description) values (8,'James','Cat','19960917','20020415',1232.78,'Vancouver','Tester');

或批量插入：

insert into Employee(id,first_name,last_name,start_date,end_Date,salary,City,Description) values (8,'James','Cat','19960917','20020415',1232.78,'Vancouver','Tester'),(7,'David','Larry', '19901231','19980212',7897.78,'New York', 'Manager');

select查询表数据：

SELECT * FROM Employee WHERE (id,first_name) = (1,'Jason');
