I’ve been using Eclipse PDT for some time now, and since PHP programming invariably involves connecting to a database at some point or another, I wanted to be able to access my MySQL databases from within the Eclipse IDE - even if only to quickly debug SQL statements. I generally use a combination of a locally installed phpMyAdmin, MySQL Administrator, MySQL Query Browser, and now the Eclipse SQL Explorer Plugin, which give me all the functionality I need for Web Application development.
phpMyAdmin, MySQL Administrator and MySQL Query Browser can be installed as follows, by the way:
sudo apt-get install phpmyadmin mysql-admin mysql-query-browser
Installing Eclipse SQL Explorer was pretty straight forward - I simply downloaded the archive package from Sourceforge, saved it to a directory in on my desktop (there is also a standalone client available, so be sure to download “Eclipse SQL Explorer [RCP/Plugin]” if you’re setting it up as an Eclipse plugin - here’s a direct link to the latest plugin file), and extracted the files:
cd ~/Desktop/sqlexplorer
unzip sqlexplorer_plugin-3.5.0.RC5.zip
This created two directories (features and plugins) along with two text files. To install the plugin, I just copied the two directories to my Eclipse root installation directory (see my previous post “Eclipse PDT IDE for PHP MySQL 32 Bit install on 64 Bit Ubuntu“), which is /opt/eclipse32
cp -R features plugins /opt/eclipse32/
Notice there was no need to use the sudo command before copying, since my user owns the eclipse32 folder.
Once installed, I also had to do some additional setup before I could configure SQL Explorer to connect to my local MySQL databases via Eclipse - namely, download and install the Java Connector for MySQL (MySQL JDBC Driver), to enable JDBC connections. The latest driver (5.1 at the time of writing) tar.gz file can be downloaded from the MySQL site here.
Once downloaded, I just extracted the files, and entered the new directory:
cd ~/Desktop/mysqljdbc
tar -zxvf mysql-connector-java-5.1.6.tar.gz
cd mysql-connector-java-5.1.6
The important file here (along with the documentation, of course) is the mysql-connector-java-5.1.6-bin.jar file, which is the driver itself. I guess this could be placed anywhere, since we just need to point the SQL Explorer plugin to it when setting it up in Eclipse, but for convenience and tidiness, I moved it to the /usr/share/mysql directory:
sudo cp mysql-connector-java-5.1.6-bin.jar /usr/share/mysql
With the JDBC driver installed, I could set up the Eclipse SQL Explorer plugin. In Eclipse, I went to Window->Preferences and expanded the new SQL Explorer section, highlighting “JDBC Drivers”, then double clicking on “MySQL Driver” to open the MySQL setup dialog:
In the MySQL Driver setup, I had to point the plugin to the MySQL JDBC Driver, by clicking on the “Extra Class Path” tab, and then clicking “Add” to point it to /usr/share/mysql/mysql-connector-java-5.1.6-bin.jar. Once added, clicking on “List Drivers” will bring up the list of available drivers in the “Driver Class Name” pull down menu. Only one is listed, and it just so happens to be the one we need - com.mysql.jdbc.Driver:
Click OK, and the driver is set up! I also clicked the “Set Default” button, since MySQL is currently the only database I connect to. With the Driver set up, I could then set up a connection to my database system. If the “Connections” view is not already available, it has to be selected via the Window->Show View->Other menu, and clicking on the “Connections” view within the “SQL Explorer” folder in this dialog.
With the Connections View available, I could set up the new connection profile, by right clicking in the view and selecting “New Connection Profile”, which opens up a new dialog, in which the new connection data is input:
It was a pretty simple process to create the connection - I just needed to replace the relevant parameters in the JDBC connections string with my connection details, so
jdbc:mysql://<hostname>[<:3306:>]/<dbname>
became
jdbc:mysql://localhost:3306/mydatabase
Entered the DB username and password, gave the connection a name, selected the newly created MySQL Driver, and clicked OK to save the connection. Double clicking the connection name in the Connections View connects to the DB and brings up an SQL window form which Queries may be run. By default, the results are displayed in a small view at the bottom of the main Eclipse IDE window - although, this can be dragged and placed anywhere. There are also several other views available via the Window->Show View->Other menu within the SQL Explorer section to peruse.
The Eclipse SQL Explorer homepage has extensive documentation available, including a cool section on extending the plugin. Maybe I should learn Java too?
That’s all Folks.

Hi,
Thank you for the tutorial. Everything works i have connected my eclipse to phpmyadmin. with the editor the queries works.
Created the connetion everything perfect.
But now my question when write my connection file in php what is the variables values :
$host=”localhost”?
$username=”root” ?
$password=”" ?
(the “?’ means is it the write value? and between”" are the current value not working)
I am getting the problem my php file doesn’t connect to the sql server giving me the error :
“Warning: mysql_connect() [function.mysql-connect]: Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2) in /home/www/Desktop/deitel&deitel/Test/login/membercreatetable.php on line 8″
Would you please explain to me what i am doing wrong!
thank you

(the “?’ means is it the right value? and between”” are the current value not working)

Hi Abibabou,
the error you’re getting is actually due to the MySql client being unable to locate the socket to connect to the server, and not your PHP script. The client is looking for the socket in /tmp/mysql.sock, but for your istallation, the mysql.sock is located somewhere else. You’ll need to find where this file is on your system (possibly /var/lib/mysql/mysql.sock), which can be done by running:
sudo find / | grep 'mysql.sock'Once you know where it is, edit your my.cnf file (/etc/my.cnf or /etc/mysql/my.cnf - location depends on your system) to tell mysql to point to the correct socket file. If there isn’t a [client] section in the my.cnf file, add it, or if it currently exists, edit the section with the new socket location, e.g.:
[client]socket=/var/lib/mysql/mysql.sock
Save the file, and restart Mysql.
Hope that helps!

After the installation of SQL Explorer plugin for Eclipse I was not able to connect to any MySQL database. I found your blog post and it learned me (how) to install the MySQL JDBC Driver… Thanks for this useful info!

Code font where achieve?

Thanks a ton! Especially the “Java Connector for MySQL” did the trick for me.
