Java DatabaseMetaData getSQLKeywords() method with example

JDBCJava8Object Oriented ProgrammingProgramming

This method retrieves the list of all the SQL keywords of the underlying database and returns in the form of a String variable which holds all the keywords separated by commas.

To get the list of keywords in the database −

  • 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 retrieve the string list of the keywords of the underlying database, by invoking the getSQLKeywords() method of the DatabaseMetaData interface.

Example

Following JDBC program establishes connection with MySQL database, retrieves the list of keywords of the underlying database.

import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.StringTokenizer;
public class DatabaseMetaData_getSQLKeywords {
   public static void main(String args[]) throws SQLException {
      //Registering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Getting the connection
      String url = "jdbc:mysql://localhost/example_database";
      Connection con = DriverManager.getConnection(url, "root", "password");
      System.out.println("Connection established......");
      //Retrieving the meta data object
      DatabaseMetaData metaData = con.getMetaData();
      //Retrieving the keywords of the underlying in the database
      String sqlKeyWords = metaData.getSQLKeywords();
      StringTokenizer tokenizer = new StringTokenizer(sqlKeyWords, ",");
      while(tokenizer.hasMoreElements()) {
         System.out.println(tokenizer.nextToken());
      }
   }
}
