Create a table named employee data with fields – id, name, and city.ĬREATE TABLE test_schema.employee (id INT AUTO_INCREMENT NOT.Let’s create some sample data in our DB to illustrate this with an example. schemaName – Name of the database schema that you are connecting to.For local execution, it’s most of the times 3306. Port – Port on which MySQL server instance is running.For our case, as we are running on local, it would be localhost. Host – This is the name of the host where the MySQL server instance is hosted.jdbc:mysql is the protocol that we are using.Here’s the format of the connection String for connecting to a database on MySQL through Java jdbc:mysql://host:port/schemaName? For this, we would require details like MySQL DB username, password, port, and database name where we would like to connect. Once the required packages are included in the classpath, let’s now see how we can make the connection to the MySQL server instance. Depending on the specific use cases this version can be changed as appropriate.įor most of the simple query executions, this version does not make a lot of changes. Note: In the above gradle library, you can notice the version of MySQL connector being added i.e. Once this package is resolved by gradle, you would see the corresponding JARs being added to the classpath. implementation group: 'mysql', name: 'mysql-connector-java', version: '8.0.23' Hence, in your adle file, you can include the below package. However, in order to reduce the complexity and above setup, you can directly include the mysql connector package through gradle, which would do all the work for us. We can download the Driver or Connector from the MySQL official website depending on the platform that we are using and then include the JAR file in the class path. In this step, we essentially import or include the JDBC driver package in the Application class where the MySQL JDBC APIs are being used. You can refer to the below figure for more details.įirst, let’s try to understand the different components involved in this entire setup. Similar to MySQL, all the other RDBMs have their own variants of the MySQL Connector which essentially implements the JDBC API and act as an interface or bridge to connect Java Application to the MySQL database. If you refer to the above figure, JDBC is a protocol to connect to any given RDBMS (Please note that this is applicable only for RDBMS systems and not for non-RDBMS’s like Mongo, etc) We will be setting up a simple Java application and running simple JDBC queries. In this section, we will learn to use the MySQL connector i.e. The series of steps would remain the same for all the different types of connectors. In this tutorial, we will learn how to use Java and Python connectors.
