This differs from other types of joins, like inner joins, which only include rows that have matching values in both tables.

One of the most basic functions of database management is running a SQL database query. It is essential that anybody using a database-driven website know how to run a successful SQL database query as well. These queries can be used for a number of reasons, and can also make many tasks that need to be completed much easier. If you want to know how to run a successful SQL database query, then follow the steps below. • The first step you will want to take is to log into the control panel for you web host. Once you have logged into the control panel, look for the phpMyAdmin option. Click this link to be taken to the administration area of your databases. • Once you have entered into the phpMyAdmin screen, the list of SQL databases available on your server will be listed on the left side of the screen. Find the database you want to run queries on, and click that database. Once you have clicked the database you want to run queries on, you will be taken to the administration screen for that specific database. • After you have opened the administration screen for the specific database you want to run queries on, you will want to open the query window. You can open the query window by clicking on the SQL link for that database. You can find this link in two locations, the first being in the left column of the screen. In the middle of probably five different icons you should find one that says SQL. The other place this will be located is in the main window, the second tab will be labeled as SQL. • In the SQL database screen, you will simply type your database query in the box and click “Go.” Once you have clicked Go, your database query will be run and any changes that need to be made will be done so automatically. Before performing these steps, or any steps which involve making changes to your software, you should make sure you know what you are doing. Running a SQL database query without knowing what you are truly doing can cause harm to your computer or completely damage your website.
