Features of phpMyAdmin

Accessing phpMyAdmin

The Interface

The left-hand side of the screen contains the following icons; home, log out, query window (for executing SQL queries), phpMyAdmin documentation and the link to the MySQL Reference Manual. Below the icons is a Databases drop-down menu, that allows you to jump to the database of your choice. The tables will be displayed below the database you selected.

The Interface

The root account has all privileges and should be used for administration purposes only. For security reasons, we are going to create a different user account with restricted access. On the home page click Privileges and then click Add a new User.

The password field is optional. You can chose a password yourself or have one generated for you. We are giving the user basic access, therefore we're only ticking the checkboxes that will give them basic rights. For instance, they will not be able to delete a database. Click Go to set the privileges. You can apply privileges to databases and tables and columns within a database.

You should then be prompted to create a table in the database. We're going to create a table called books and enter 4 in the number of fields. Enter the following fields: ISBN, Author, Title and Price.

Next, set the data types and length/values as show below. The ISBN will serve as the primary key.

Create Table

To set the primary key, choose the database and then the table and click on the primary icon as shown below.

To insert data into the table, select book_shop from the drop-down on the left-hand side and then the books table below it. Click on the Insert tab and continue to fill in the different fields with values, as shown below.

Insert Data into table

To view and manage your database, select it in the drop-down on the left-hand side. You will get an overview of your database and nine tabs for carrying out certain actions. Below is a description of the different tabs.

Structure: displays the different tables in the database and allows you to create a new table. A small drop-down menu, lets you perform the following on table/s you have selected; empty, drop, print view, check, optimise, repair and analyse. The Action section provides the following options: browse, search, display the structure, insert a record, empty or drop a table.

SQL: lets you execute SQL queries on the database. Search: lets you search for words and phrases in the

database. Query: allows queries to be executed using the interface

components and manual SQL queries to be run.

Managing your databases

rename and copy the database. Privileges: shows what users have access to

the current database and their rights. You also have an edit option next to each user. Drop: lets you delete the database if you need to.
