Executing a SQL file - mysql

Question

I am very new to MySQL. I have an SQL file called tables.sql as shown below.
I uploaded it to a subfolder in my public_html folder.
When I copy the below into a MySQL query and run it, I get this error: "Documentation #1046 - No database selected".
How can I execute this to create a table? When I go to http://mywebsite.com/subfolder/tables.sql it says Page not found

Answer 1

Connect to the MySQL Client, and when you have authenticated yourself, and created the database (create database [database name];) then just execute the script with the command:
\. tables.sql

Answer 2

If your database was not created, create it first like this:
mysqladmin -uroot -p myRootPassword create myDatabaseName
If root has no password setup, forget the -p myRootPassword
Then run the following command from your the command line, being in your public_html folder:
mysql -u root -p myRootPassword mydatabaseName < tables.sql
Replace myRootPassword by your mysql root password and mydatabaseName by your database name.
If root has no password setup run it like this:
mysql -u root -p myRootPassword mydatabaseName < tables.sql

Answer 3

The geeky approach:
Step 1. Create your database:
mysql -h yourHost -u yourUser -pYourPassword -e"create database dbName";
(if you are working on localhost, you can omit the -h yourHost piece.
Step 2. Load your file on the newly created database:
mysql -h yourHost -u yourUser -pYourPassword dbName < tables.sql
