How to create a table in Java with JDBC Connection?

By using CREATE TABLE query we can create table.

Syntax

CREATE TABLE table_name(
column1 datatype,
column2 datatype,
column3 datatype,
.....
columnN datatype,
PRIMARY KEY( columns )
);

 

To create a table with JDBC we need to follow these steps

  • Register the driver − Register the driver class using the registerDriver() method of the DriverManager class. Pass the driver class name to it, as parameter.
  • Establish a connection − Connect ot the database using the getConnection() method of the DriverManager class. Passing URL (String), username (String), password (String) as parameters to it.
  • Create Statement − Create a Statement object using the createStatement() method of the Connection interface.
  • Execute the Query − Execute the query using the execute() method of the Statement interface.

 

Example

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class CreateTableExample {
   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......");
      //Creating the Statement
      Statement stmt = con.createStatement();
      //Query to create a table
      String query = "CREATE TABLE Employees("
         + "ID INT NOT NULL, "
         + "NAME VARCHAR (20) NOT NULL, "
         + "AGE INT NOT NULL, "
         + "SALARY DECIMAL (18, 2), "
         + "ADDRESS VARCHAR (25) , "
         + "PRIMARY KEY (ID))";
      stmt.execute(query);
      System.out.println("Table Created......");
   }
}

 

Output

while run the above program will return following output

Connection established......
Table Created......
