Java – Creating a table using JDBC PreparedStatement interface

In this article, we will use JDBC API to create table in MySQL database from Java application (i.e.; using PreparedStatement Interface)

1. Pre-requisite:

  • Java JDK 1.8.0_77
  • MySQL database 5.5.16
  • Eclipse Luna IDE 4.4.0
  • mysql-connector-java-5.1.38.jar file

2. Database parameters :

Let us move on and code an example to connect MySQL database from Java application to create a table using JDBC API. But before that, we will list down required things to connect database

  • database server IP or address (localhost)
  • sever port (3306)
  • database name (PLAYER_INFO)
  • username (root)
  • password (root@123)

Note: All bold are database values to connect MySQL database

3. Creating a table using JDBC PreparedStatement Interface :

  • As we are ready with required things to connect MySQL database from Java application
  • We can use one of the methods from PreparedStatement Interface to execute “create table” SQL query
    1. execute();
    2. executeUpdate();
    3. executeQuery();
  • Let us code a simple example using PreparedStatement Interface

CreateTableUsingJDBCPreparedStatement.java

package in.bench.resources.mysql.db.example;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class CreateTableUsingJDBCPreparedStatement {

	public static void main(String[] args) {

		// variables
		Connection connection = null;
		PreparedStatement preparedStatement = null;

		// Step 1: Loading or registering MySQL JDBC driver class
		try {
			Class.forName("com.mysql.jdbc.Driver");
		}
		catch(ClassNotFoundException cnfex) {
			System.out.println("Problem in loading MySQL JDBC driver");
			cnfex.printStackTrace();
		}

		// Step 2: Opening database connection
		try {

			// Step 2.A: Create and get connection using DriverManager
			connection = DriverManager.getConnection(
          "jdbc:mysql://localhost:3306/PLAYER_INFO", "root", "root@123"); 

			// create SQL query to create new table PLAYER
			String sqlQuery = "CREATE TABLE PLAYER (" +
					" PLAYER_ID INT(6) NOT NULL AUTO_INCREMENT, " +
					" NAME VARCHAR(50) NOT NULL, " +
					" AGE INT(3) NOT NULL, " +
					" MATCHES INT(3) NOT NULL, " +
					" PRIMARY KEY (`PLAYER_ID`))";

			// Step 2.B: Creating JDBC PreparedStatement
			preparedStatement = connection.prepareStatement(sqlQuery);

			// Step 2.C: Executing SQL & retrieve data into ResultSet
			int sqlQueryResult = preparedStatement.executeUpdate();

			// output of database creation
			if(0 == sqlQueryResult) {
				System.out.println("New table created successfully");
			}
			else {
				System.out.println("Error in creating table");
			}
		}
		catch(SQLException sqlex){
			sqlex.printStackTrace();
		}
		finally {

			// Step 3: Closing database connection
			try {
				if(null != connection) {

					// cleanup resources, once after processing
					preparedStatement.close();

					// and then finally close connection
					connection.close();
				}
			}
			catch (SQLException sqlex) {
				sqlex.printStackTrace();
			}
		}
	}
}

Output:

New table created successfully

Note: This demo example is to showcase that creating & dropping table using JDBC API is possible using PreparedStatement Interface and generally don’t use this in practical scenario
