creating a database in mysql from java

Question

Could you help with this problem.

I\'m trying to create and then use a database called TIGER.

I have no problem if I create the database in MySQL and it runs

Answer 1

Few points to note and correct-

1. You have declared Connection Object as private Connection con; but you are using it as statement = Conn.createStatement();

2. You have declared a reference to Prepared Statement private PreparedStatement statement; but you are creating instance of Statement statement = Conn.createStatement();. Your code should be -

   try {
       Connection con = DriverManager.getConnection("jdbc:mysql://localhost/?user=root&password=rootpassword");
       Statement  statement = con.createStatement();
       int myResult = statement.executeUpdate("CREATE DATABASE IF NOT EXISTS TIGER"); //should get 0
   }
   catch (SQLException e) {
       System.out.println("Database creation failed");
       e.printStackTrace();
   } 
   

Note that when the return value for executeUpdate is 0, it can mean one of two things:

• The statement executed was an update statement that affected zero rows.

• The statement executed was a DDL statement.
