Java DatabaseMetaData getJDBCMajorVersion() method with example
The getJDBCMajorVersion() method of the DatabaseMetaData interface returns the major version of the JDBC driver in integer format.
To get major version of the JDBC driver −
Make sure your database is up and running.
Register the driver using the registerDriver() method of the DriverManager class. Pass an object of the driver class corresponding to the underlying database.
Get the connection object using the getConnection() method of the DriverManager class. Pass the URL the database and, user name, password of a user in the database, as String variables.
Get the DatabaseMetaData object with respect to the current connection using the getMetaData() method of the Connection interface.
Finally, get the major version of the JDBC driver using the getJDBCMajorVersion() method of the DatabaseMetaData interface.
Example
Following JDBC program establishes connection with MySQL database, retrieves and, displays the major version of the JDBC driver.
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DatabaseMetaData_getJDBCMajorVersion {
public static void main(String args[]) throws SQLException {
//Registering the Driver
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//Getting the connection
String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
System.out.println("Connection established......");
//Retrieving the meta data object
DatabaseMetaData metaData = con.getMetaData();
//Retrieving the major version of the JDBC driver
int version = metaData.getJDBCMajorVersion();
System.out.println("Major JDBC version number of the JDBC driver: "+version);
}
}Output
Connection established...... Major JDBC version number of the JDBC driver: 3
