Introduction
The Eclipse Data Tools Platform (DTP) is a new top-level project at eclipse.org. Originally proposed by Sybase in February 2005, DTP has attracted strong community support and is currently managed by a committee comprised of Sybase, IBM and Actuate. It is an open source initiative designed to provide solutions in the data framework and tooling domains. The Eclipse Data Tools Platform (DTP) is a standard Eclipse plugin that you can use to perform most database development and query functions. The DTP plugin supports several database platforms via JDBC, including Derby, Oracle, MS SQL, Postgres, Sybase ASA, Flat Files, XML Data, and more. This post covers connecting to MySQL and basic DTP features. Eclipse includes:
- Connect to a database (or multiple databases)
- View database object trees (tables, views, stored procedures, etc.)
- Generate data definition language (DDL) from database objects
- Execute DDL commands against a database
- Execute standard query language (SQL) queries against a database
- View query results in table format
System Requirements
- Java SE Development Kit (JDK) 6
- Eclipse IDE for Java EE Developers [Ganymede]
- MySQL 5.1.37 GA Community Server Edition
- MySQL Connector/J 5.1.8, JDBC driver for MySQL
Article Prerequisites
- I’ll assume that you’re comfortable installing Eclipse and Eclipse plugins.
- Installing and running MySQL Database
- Double click mysql-5.1.37-win32.msi.
- Click Next and select Complete Setup Type. Click Next and click Install.
- After installing MySQL, check Configure the MySQL server now and click Finish.
- In MySQL Server Instance Configuration Wizard, click Next. Select Detailed Configuration, click Next.
- Select Developer Machine, click Next, select Multifunctional Database and click Next. Click Next again.
- Select Decision Support (DSS)/OLAP and click Next. Check Enable TCP/IP Networking and leave default port 3306. You can change if you want to. Also select Enable Strict Mode and click Next.
- Select Standard Character Set and click Next.
- Select Install As Windows Service, select Service Name, check Launch the MySQL Server automatically. Select Include Bin Directory in Windows Path. Click Next.
- Check Modify Security Settings and give Password. Click Next and click Execute. Click Finish.
Installing/Setting up MySQL JDBC Driver and Connection Profile
Select File > New > Other. Expand Connection Profiles and select Connection Profile, click Next >.
Alternatively, you can select Data Source Explorer TAB, right click Database Connections, and select New…
Select MySQL as Connection Profile Type. Name the Connection Profile for the host and database to which you’re connecting (i.e. localhost.database). We are giving name MyMySQLConnection. Click Next >.
Click New Driver Definition button which will open new dialog box. Select Name – MySQL JDBC Driver and System Version – 5.1
Eclipse will give error as “Unable to locate JAR/Zip in the file system.”.
Select Jar List TAB. Click Add JAR/Zip… button and select mysql-connector-java-5.1.8-bin.jar. Press OK.
On the General TAB, update following fields and select Save password checkbox.
- Database: mysql
- URL: jdbc:mysql://localhost:3306/mysql
- User name: root
- Password: password
Click Test Connection to check connection has been successfully establish. Click Finish
Open Database Development Perspective
With a connection template and profile defined, open up the Database Development Perspective, if it isn’t already open.
Select Window > Open Perspective > Other…. Select Database Development, click OK.
Connecting to MySQL Database
Above steps will connect to database. In case Eclipse is not connected to database, then follow these steps:
- In the Data Source Explorer pane, expand the Database Connections folder.
- Right-click on the Connection Profile and select Connect.
- You should now see folders for table, stored procedures, views, and other objects supported by your database platform.
- If you have tables in your database, expand to view columns.
Create, Insert, Edit and Execute SQL Files
You can create and modify tables, triggers, stored procedures directly via DTP. Before proceeding, open an existing or create a new Eclipse project. You’ll save SQL files to an existing project which makes it easy to place them under version control with the rest of your application files.
Select File > New > SQL File (or File > New > Other > SQL Development > SQL File). Click Create Project… in Create SQL File dialog. Select General > Project. Click Next.
Name the project MyFirstSQLProject. Click Finish.
Give File name as MyFirstSQL.sql. Select database server type as MySql_5.1. Select connection profile name as MyMySQLConnection. Select database name as test. Click Finish.
NOTE: MySQL by default has three databases when you install it. information_schema, mysql, and test
Type in the SQL you’d like to run. Select all, or a portion, of the SQL to run. Right-click in the document tab and select either Execute All, Execute Selected Text, or Execute Selected Text As One Statement. Review the SQL Results at the bottom of the SQL Development Perspective.
Right-click on a table and select Data > Edit. An editor tab appears with the table’s columns, enter one or many records into the rows provided. Right-click anywhere in the editor panel and select Save.
If your SQL statement executes successfully, you should see the results of the statement in the Results view. If the statement was a query, the Results view will display the returned records. If it’s not a query, you’ll be notified of the statement’s success and how many rows were affected.
Summary
In this tutorial, we learned how to:
- Define a driver template
- Create a connection profile
- Connect to a MySQL 5.1.37 database
- Run SQL statements against a MySQL 5.1.37 database from within the Eclipse IDE
