Which database you are using?

If you are using Mysql database then this query works.

Here is the java code for creating a table.

import java.sql.*;
class CreateDatabaseTable 
{
    public static void main(String[] args) 
    {
        try{
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql", "root", "root");
            Statement stmt=con.createStatement();
            String table = "create table file ( file_id int , file_data text)"; 
            stmt.executeUpdate(table);
            System.out.println("Table is created successfully!");
        }
        catch(Exception e){
            System.out.println(e);
        }
    }
}
