  • mysql在命令行中,指定要连接的数据库?

    需求描述

      mysql客户端,可以在登录到mysql数据库时,指定要连接到哪个数据库

      这里进行一个测试。

    测试过程:

    1.mysql通过-D参数指定连接到test数据库

    [mysql@redhat6 scripts]$ mysql -uroot -p -D test
    Enter password: 
    ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
    [mysql@redhat6 scripts]$ mysql -uroot -p -D test
    Enter password: 
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 14
    Server version: 5.5.57-log MySQL Community Server (GPL)
    
    Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.

    owners.
    
    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.
    
    mysql> select database();
    +------------+
    | database() |
    +------------+
    | test       |
    +------------+
    1 row in set (0.00 sec)

    备注:通过在-D参数后面指定数据库名字,就连接到了test数据库。

    2.通过-D参数,连接到test01数据库

    [mysql@redhat6 scripts]$ mysql -uroot -p -D test01
    Enter password: 
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 15
    Server version: 5.5.57-log MySQL Community Server (GPL)
    
    Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.
    
    Oracle is a registered trademark of Oracle Corporation and/or its
    affiliates. Other names may be trademarks of their respective
    owners.
    
    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.
    
    mysql> select database();
    +------------+
    | database() |
    +------------+
    | test01     |
    +------------+
    1 row in set (0.00 sec)
    
    mysql> 

    备注:通过在-D参数后面指定数据库名字,就连接到了test01数据库。

    小结:通过-D 参数指明要直接连接到哪个数据库。
