mysql在命令行中，指定要连接的数据库？

[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:

mysql> select database();

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

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。
