Learn How To Use MySQL Online
Most webmasters have started to learn HTML before they moved on to programming languages such as PHP. With PHP come databases like MySQL as the primary storage for project data. Many popular on-line applications, such as WordPress, use the PHP and MySQL combination to power sites online.
You usually do not need to know PHP or MySQL if you download and install an application like WordPress. But if you want to begin developing your own applications, or modifying existing ones, then you need to know the ins and outs of SQL database commands.
Head first SQL: Hands On is a free service by O’Reilly that can be used to learn and execute MySQL queries online. when you open the Head First Labs site for the first time you see a form near the top that you can use to run MySQL commands.
The service provides access to several tables that are listed above the form. All you need to do is to enter a SQL query in the form to execute it. The core benefit of testing SQL commands here is that you do not have to create your own database first and fill it with data. Plus, you can’t really damage the database or tables this way.
The results are displayed right beneath the for. But the site offers more than just an option to run your own MySQL queries, which is especially useful for users who are just getting started and do not know anything about SQL.
The Get Started section of the page lists 33 MySQL lessons. The majority of lessons teach a specific command or command sets. This ranges from basic queries such as SELECT or INSERT to more complex operations. Not all lessons make sense, which can be attributed that some require that you have read the Head First SQL: Hands On book.
Some on the other hand can be used without having the book in reach. MySQL beginners will probably like the form on the begin page the most, as it grants them to run custom SQL queries on sample database tables.
