JDBC - Drop Table Example

This chapter provides an example on how to delete a table using JDBC apppcation. Before executing the following example, make sure you have the following in place −

To execute the following example you can replace the username and password with your actual user name and password.

Your MySQL or whatever database you are using, is up and running.

NOTE Reformatting JDBC Tutorial This is a serious operation and you have to make a firm decision before proceeding to delete a table, because everything you have in your table would be lost.

Required Steps

The following steps are required to create a new Database using JDBC apppcation −

Import the packages − Requires that you include the packages containing the JDBC classes needed for database programming. Most often, using import java.sql.* will suffice.

Open a connection − Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with a database server.

Execute a queryReformatting JDBC Tutorial Requires using an object of type Statement for building and submitting an SQL statement to drop a table in a seleted database.

Clean up the environment Reformatting JDBC Tutorial try with resources automatically closes the resources.

Sample Code

Copy and paste the following example in JDBCExample.java, compile and run as follows −

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

pubpc class JDBCExample {
   static final String DB_URL = "jdbc:mysql://localhost/TUTORIALSPOINT";
   static final String USER = "guest";
   static final String PASS = "guest123";

   pubpc static void main(String[] args) {
      // Open a connection
      try(Connection conn = DriverManager.getConnection(DB_URL, USER, PASS);
         Statement stmt = conn.createStatement();
      ) {		      
         String sql = "DROP TABLE REGISTRATION";
         stmt.executeUpdate(sql);
         System.out.println("Table deleted in given database...");   	  
      } catch (SQLException e) {
         e.printStackTrace();
      } 
   }
}

Now let us compile the above example as follows −

C:>javac JDBCExample.java
C:>

When you run JDBCExample, it produces the following result −

C:>java JDBCExample
Table deleted in given database...
C:>
