To access SQL via the command line we simply navigate to the xampp folder. the folder is usually on the c: drive.
type: cd c:xamppmysqlin then press enter.
type: in mysql -u root -p then press enter.
in the new line enter the password of the database.
type: show databases; to see all the databases that you have access to.
once you know what database you want to use type (ex. cms_database), type use cms_data or any other db_name, it should say Database changed
// Bonus Note you shouldn't use the root user when working with databases. you would want to create a separate account (ex. cms_user) with special privileges to limit errors.
to do that type:
GRANT ALL PRIVILEGES IN cms_database.*
TO 'cms_user'@'localhost'
IDENTITIED BY 'yourpassword'
double check by using the command:
SHOW GRANT FOR 'cms_user'@localhost;
if you already have the name of the user and the specific database you wish to use, change step 2 to this.
mysql -u cms_user -p cms_database
