Copy One Database Table to Another

     

In this section, you will learn to copy one database table to another database table. That means we copy one table to a different table but it contains a similar type of field or column. These tables aren?t in same database. Both the MySQL databases are different i.e. jdbc4 and jdbcMysql. The "jdbc4" database has "Copyemployee" table and "jdbcMysql" database also has a "Roseindia" table.

To copy the table you need to establish the connection with the MySQL database (jdbcMysql). When the connection is established then sql statement (?INSERT INTO Roseindia SELECT * FROM jdbc4.Copyemployee?) is executed and rows get copied. Once the rows get copied then it will display a message - ?number of row(s) affected!?. Whenever any row is not copied then it shows a message -  ?Don?t add any row!?.

Syntax for copy table:

?INSERT INTO <new_table_name> SELECT * FROM <Database_name.old_table_name>

Here is the code of program:

import java.sql.*;

public class CopyOneDatabaseTableToAnother {
  public static void main(String[] args) {
  System.out.println("Copy data from one database table to another!");
  Connection conn = null;
  String url = "jdbc:mysql://localhost:3306/";
  String dbName = "jdbcMysql";
  String driver = "com.mysql.jdbc.Driver";
  String userName = "root"
  String password = "root";
  try {
  Class.forName(driver).newInstance();
  conn = DriverManager.getConnection(url+dbName,userName,password);
  Statement st = conn.createStatement();
  //Copy table
  int rows = st.executeUpdate("INSERT INTO Roseinda SELECT * 
    FROM jdbc4.Copyemployee"
);
  if (rows == 0){
  System.out.println("Don't add any row!");
  }
  else{
  System.out.println(rows + " row(s)affected.");
  conn.close();
  }
  }
  catch (Exception e) {
  e.printStackTrace();
  }
  }
}
