It is recommended to create new connection to avoid using "root" user ("ERROR: Unable to Connect to Database.In the above screenshot, I have setup a new connection named "dev". Step 3: Establish Java MySQL connectionĬonnection = DriverManager.getConnection(URL, USER, PASSWORD) Public static final String DRIVER_CLASS = "" Public static final String URL = "jdbc:mysql://localhost/jdbcdb"

Private static JDBCMySQLConnection instance = new JDBCMySQLConnection() Step 1: Use interfaces from java.sql package To complete the above steps, create a new class JDBCMySQLConnection in package and copy the following code.

YOUR_DATABASE_NAME is the MySQL database name, in this example it is “jdbcdb”.

3306 is the default port number for MySQL, which can be omitted if not changed to any other number.

localhost – is the name of the server hosting your database.

Public static final String PASSWORD = "YOUR_DATABASE_PASSWORD" Ĭonnection connection = DriverManager.getConnection(URL, USER, PASSWORD) Java database connection string URL:Įxample, for Java MySQL connection string URL: Public static final String USER = "YOUR_DATABASE_USERNAME" public static final String URL = "jdbc:mysql://localhost/jdbcdb" In this example, we have created these as constant variables and passed it in getConnection() method. This method requires a JDBC MySQL connection URL string, MySQL database username and password. We connect to MySQL from Java using DriverManager class by calling DriverManager.getConnection() method. public static final String DRIVER_CLASS = "" Ĭlass.forName(DRIVER_CLASS) Establish Java MySQL connection In the below code, we have created a static final String variable (constant) and passing it as parameter to class.forName as shown below.

Mysql connectorj install path driver#

The statement Class.forName (“”) loads the MySQL Java driver class in memory. This connector JAR file needs to be included in the client project’s classpath which is explained later under Configure JDBC Driver in Eclipse. The Java MySQL driver () is available in the downloaded Java MySQL Connector JAR file. You need to import required classes/interfaces from java.sql.* package which acts as a bridge between Java application and database. We write a class ( JDBCMySQLConnection) defining database connection configuration statements and methods to make JDBC connect to MySQL database.įollowing steps are involved in JDBC MySQL connection. If you are a newbie, refer this link on getting started with Java and Eclipse. Create a new Java Project and name it as “ JDBCMySQLSample“.Create the following tables inside this database.įoreign key references department(dept_id).Create a database in MySQL and name it as “ jdbcdb“.This JDBC MySQL example uses a sample database “ jdbcdb” which contains the following table

Unzip the connector to a safe location on your computer which contains MySQL Connector/J JAR. This tutorial uses JDBC MySQL connector 5.1 version.

The Java MySQL connector JAR can be downloaded from.

MySQL Connector/J is the official MySQL JDBC driver.

These files must be in our classpath (which is explained later under Configure JDBC Driver in Eclipse) otherwise we will get some class-not-found-exceptions indicating that the driver was not found on the classpath.

This connector is typically delivered with the product in a jar or zip file or available in the provider’s website. To reach the database using JDBC we need a JDBC driver from the database provider in our case – MySQL. The JDBC database Connector provides access to the database. A database specific driver is required for each database which implements the JDBC API. JDBC API mostly consists of interfaces which work independently of any database. Refer this tutorial on MySQL for creating database and tables, inserting data into tables, etc.

This Java database application uses MySQL as sample database.

This MySQL JDBC example requires MySQL database to be installed. Alternatively, you can use any Integrated Development Environment (IDE) (such as Eclipse, NetBeans, etc).
