You can compile Java database programs without the JDBC driver.
The MySQL's JDBC driver is called "MySQL Connector/J" and is available at MySQL mother site.
You need to install an appropriate JDBC (Java Database Connectivity) driver to run your Java database programs.
Install MySQL JDBC Driver ( IMPORTANT - Don't MISS This Step!) This step is important otherwise, you will be out-of-sync with this article and may not be able to find your files later. I shall assume that you have created a directory called " c:\myWebProject" (for Windows) or " ~/myWebProject" (for macOS) in your earlier exercises. A programming text editor, such as Sublime Text, Atom.Ĭreate a Directory to Keep all your Works.
JDK (Read " How to install JDK and Get Started").Install JDK and Programming Editorīefore you proceed, I shall assume that you are familiar with Java Programming and have installed the followings:
Your client programs shall connect to the database server at the given IP address and TCP port number, issue the SQL commands, and process the results received. On MySQL, instead of using the " mysql" command-line client program provided, you can write your own client programs (in Java or other languages) to access the MySQL server. I shall assume that the MySQL server is running on the default TCP port number 3306. Install MySQL (Read " How to Set Up MySQL and Get Started"). For other database systems, read " Other Databases". In this article, I shall describe the MySQL Relational Database Management System. Otherwise, read " Introduction to Relational Database and SQL". I presume that you have some knowledge on Relational Databases and the SQL language. Also you should always close the database connection once you complete interacting with database by calling close() method of the Connection object.Relational Database and Structure Query Language (SQL) Therefore, when you create a Connection object, you should always put it inside a try catch block. in such cases, JDBC throws a SQLException. When connecting to MySQL, anything could happens e.g., database server is not available, wrong user name or password, etc. String url = "jdbc:mysql://localhost:3306/mysqljdbc" Ĭonn = DriverManager.getConnection(url, user, password) Connecting to MySQL databaseįirst, you need to import three classes: SQLException, DriverManager, and Connection from the java.sql.* package. Third, click on the Add JAR folder button, browse to the location where you installed MySQL Connector/J, and choose the JAR file as screenshot below after that click OK button.
Second, on the left hand side of the project properties dialog, from the Categories section, choose Libraries item. The project properties dialog will appear. To load MySQL Connector/J into your program you follow three steps below:įirst, in NetBeans IDE, from project name, right mouse click and choose properties menu item. Loading MySQL Connector/J into your program
Then you can use this Connection object to execute queries. Create a new Connection object from the DriverManager class.Load the MySQL Connector/J into your program.To connect to MySQL database from a Java program, you need to do the following steps: In this tutorial, you will learn how to connect to MySQL database using JDBC Connection object.
