2.  phpMyAdmin is a handy, graphical
administration tool written in php for
creating and managing MySQL databases ,
using a web user interface. The interface is
straight-forward and easy to learn and it
allows users to execute SQL queries manually.
It is also open source, so you can download
and use it for free.

3.  Create, drop, browse and modify databases.
 Perform maintenance on databases.
 Run query operations, drop, create, update,
check, repair tables and more.
 Manage MySQL users and privileges.
 Administering multiple servers.
The full list of features can be found on official
Document on phpMyAdmin website.

4.  You can access phpMyAdmin directly visting
the following URL;
 http://localhost/phpMyAdmin
Or ur server ip address
http://192.168.13.2/phpmyadmin

6.  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.

7.  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.

9. Here are some basic operations you
can perform on your databases and
tables in phpMyAdmin:
1. Select the database you want to
use from the list on the left.

10.  Let's now create a database and call it
book_shop. Type in the name into the Create
New database field and click Create.

11.  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.

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

14.  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.

15. 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.

16.  Export: allows you to save your database into
a file format of your choice.
CSV, Excel, Word, LaTex, PDF, SQL and XML
are some of the formats available.
 Import: import an SQL file.
 Operation allows you to create a new
table, 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.

17. 2. Select the tables you want to use. When
optimizing or repairing, you should select
Check All.

18. 3. In the "With selected" dropdown
menu, select one of the following:

19.  Empty - This will empty all data from the selected
tables.
 Drop - This will drop (delete) the selected tables.
 Check Table - This will check the tables for errors.
 Optimize Table - This will perform some basic table
optimizations.
 Repair Table - This will attempt to repair your tables.
 Analyze Table - This will analyze your tables.

20.  Export – Backup database
 Import – restore database

21. 1. Select your database from the list on the
left.

22. 2. Click on "Export" from the top set of tabs.

23. 3. Select the tables from
the list that you would
like to back up. If you
want to back up the
entire database, click
"Select All."

24. 4. Make sure both the "Structure" and "Data"
boxes are selected on the right. They should
be, by default. In the Structure section, check
the "Add DROP TABLE / DROP VIEW" box if
you want this export to be able to replace
existing tables of the same name. If you want
to merge this backup with another database,
do not select this.

26. 5. Check the "Save as file" box. Also select a
compression option (such as "gzipped") if you
want to compress the backup before
downloading it from the server.
6. Click the "Go" button, and, at the prompt,
save the file to your local computer.

27. 1. Make sure the database you need has

while your database imports. Depending on
the size, this can take a few minutes.
