JDBC Statement example – Create a table

Here’s an example to show you how to create a table in database via JDBC statement. To issue a create statement, calls the Statement.execute() method like this :

Statement statement = dbConnection.createStatement();
// execute create SQL stetement
statement.execute(createTableSQL);

Full example…

package com.mkyong.jdbc;
 
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
 
public class JDBCStatementCreateExample {
 
	private static final String DB_DRIVER = "oracle.jdbc.driver.OracleDriver";
	private static final String DB_CONNECTION = "jdbc:oracle:thin:@localhost:1521:MKYONG";
	private static final String DB_USER = "user";
	private static final String DB_PASSWORD = "password";
 
	public static void main(String[] argv) {
 
		try {
 
			createDbUserTable();
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		}
 
	}
 
	private static void createDbUserTable() throws SQLException {
 
		Connection dbConnection = null;
		Statement statement = null;
 
		String createTableSQL = "CREATE TABLE DBUSER("
				+ "USER_ID NUMBER(5) NOT NULL, "
				+ "USERNAME VARCHAR(20) NOT NULL, "
				+ "CREATED_BY VARCHAR(20) NOT NULL, "
				+ "CREATED_DATE DATE NOT NULL, " + "PRIMARY KEY (USER_ID) "
				+ ")";
 
		try {
			dbConnection = getDBConnection();
			statement = dbConnection.createStatement();
 
			System.out.println(createTableSQL);
                        // execute the SQL stetement
			statement.execute(createTableSQL);
 
			System.out.println("Table \"dbuser\" is created!");
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		} finally {
 
			if (statement != null) {
				statement.close();
			}
 
			if (dbConnection != null) {
				dbConnection.close();
			}
 
		}
 
	}
 
	private static Connection getDBConnection() {
 
		Connection dbConnection = null;
 
		try {
 
			Class.forName(DB_DRIVER);
 
		} catch (ClassNotFoundException e) {
 
			System.out.println(e.getMessage());
 
		}
 
		try {
 
			dbConnection = DriverManager.getConnection(
					DB_CONNECTION, DB_USER,DB_PASSWORD);
			return dbConnection;
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		}
 
		return dbConnection;
 
	}
 
}

Result

Here’s the result.

CREATE TABLE DBUSER(
  USER_ID NUMBER(5) NOT NULL, 
  USERNAME VARCHAR(20) NOT NULL, 
  CREATED_BY VARCHAR(20) NOT NULL, 
  CREATED_DATE DATE NOT NULL, 
  PRIMARY KEY (USER_ID) 
)
TABLE "user" IS created!
