Chapter 24 - MySQL

Using The MySQL Control Panel

The MySQL feature inside your Control Panel is where you manage your database, including desiging tables, adding, deleting, and updating records, all from within your web browser.

When you first click on the MySQL feature, you will be asked to provide a name for your database and a password, you can use the same username and password that you use for your Control Panel if you so desire. Once the database is created, and you return to this feature inside your Control Panel it will then become the Welcome page for your database. A tree view is on the left. The name of your database and the version of MySQL are displayed to the right of the tree.

The Tree

The top entry in the tree, “Home,” will return you to the Welcome page. Beneath that is your database name and a square with a plus or minus sign in it. Clicking the square will show and hide the names of the tables in the database in the tree. Clicking on the database name in the tree will display the main database management page. Clicking on one of the tables names in the tree will display the properties of that table.

The Main Database Management Page

This page displays a list of all the tables in your database and the number of records in each. You can also execute an SQL statement, perform advanced queries, dump the database, and create new tables.

The List of Tables

Next to each table name are links to various actions you can perform on a table.

Browse Display the records in the table 30 at a time. From the Browse page you can edit or delete a record.
Select Build and execute a SELECT query on the table. Only those records which match the criteria you provide will be displayed.
