"DROP TABLE" Statements
This section describes how to drop a table in the current database.
Sometimes you need to drop a table from the database. Dropping a table means deleting all rows of data in the table and also deleting the table definition. The following Java sample program shows you how to drop the table named "Price":
/* DropTable.java - Copyright (c) 2015, HerongYang.com, All Rights Reserved. */ import java.sql.*; public class DropTable { public static void main(String [] args) { Connection con = null; try { con = DriverManager.getConnection( "jdbc:sqlserver://localhost\\SQLEXPRESS;" + "user=sa;password=HerongY@ng;" + "database=AdventureWorks2014"); // Adding a new column to an existing table Statement sta = con.createStatement(); sta.executeUpdate("DROP TABLE Herong.Price"); System.out.println("Table dropped."); sta.executeQuery("SELECT * FROM Herong.Price"); sta.close(); con.close(); } catch (Exception e) { e.printStackTrace(); } } }
The output of this program has a SQLException showing us that the table is gone:
C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java -cp .;\local\lib\sqljdbc41.jar DropTable Table dropped. com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'Herong.Price'.
