Easier way to access mysql database tables? - mysql

In postgresql all you needed to do was type in postgres <database_name>
to access the database. In MySql, you need to do this:
mysql -u root

Is there a way to not have to specify the user name and specify the database all in one line?

Use the -D option of the program mysql the default login with a database.
The -p option let's you enter a password into the mysql program

Enter password: **

Answer 2

Other answers mention the --database / -D option, but you don't even need that.
https://dev.mysql.com/doc/refman/5.7/en/mysql.html shows the simpler example:
Using mysql is very easy. Invoke it from the prompt of your command
interpreter as follows:
shell> mysql db_name
In other words, exactly like the usage you showed for postgres <database_name>.
You may also need to supply username and password to authenticate for the MySQL instance, but I prefer to put those into an option file so I don't have to type them repeatedly.
$ cat ~/.my.cnf
[client]
username = scott
password = tiger
See https://dev.mysql.com/doc/refman/5.7/en/option-files.html for more on these files.
There's also an optional way to store the user credentials encrypted. For this https://dev.mysql.com/doc/refman/5.7/en/mysql-config-editor.html
Any software is easier to use if you try reading a little bit of the documentation! :-)

Answer 3

Using man mysql to view the mysql manpage you'll find the -D flag:
· --database=db_name, -D db_name
The database to use. This is useful primarily in an option file.
