7.笔记 MySQL学习——向表中添加行

往表中添加内容可以是insert语句，也可以是LOADDATA语句或者mysqlimport客户端程序。

1. 查看表中行数量

mysql> select * from student;

Empty set (0.00 sec)

显示为空

2. 利用INSERT添加行

mysql> insert into student values('Kyle','M',NULL);

Query OK, 1 row affected (0.00 sec)

mysql> insert into grade_event values('2012-09-03','Q',NULL);

Query OK, 1 row affected (0.00 sec)

mysql> insert into student (name,sex)values ('Abby','F'),('Joseph','M');

Query OK, 2 rows affected (0.00 sec)

Records: 2 Duplicates: 0 Warnings: 0

mysql> insert into member setlast_name='Stein',first_name='Waldo';

Query OK, 1 row affected (0.00 sec)

3. 利用文件添加新行

有两种方式，一种是直接执行如下：

[root@OEL sampdb]# mysql sampdb <insert_president.sql -u root -p

Enter password:

另一种在MYSQL下执行

mysql> source insert_president.sql

Query OK, 0 rows affected (0.02 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.01 sec)

Query OK, 1 row affected (0.00 sec)

其中insert_president.sql 文件内容如下：

Query OK, 102 rows affected (0.09 sec)

Records: 102 Deleted: 0 Skipped: 0 Warnings: 0

其中member.txt文件如下：

其中LOCAL会引发客户端程序读取数据文件，并把文件内容发送到服务器进行加载。

也可以如下

[root@OEL sampdb]# mysqlimport --local sampdb member.txt -u root -p

Enter password:

sampdb.member: Records: 102 Deleted: 0 Skipped: 0 Warnings: 0

mysqlimport 程序是根据数据文件的名字来确定表名的。
