create database Sample DB; use Sample DB; CREATE TABLE `users` ( `user_id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(45) NOT NULL, `password` varchar(45) NOT NULL, `fullname` varchar(45) NOT NULL, `email` varchar(45) NOT NULL, PRIMARY KEY (`user_id`) ); Practical Database Programming with Java - This book is for those who are beginner in Java database programming and want to catch up with the main database programming techniques with straightforward and easy to learn example code. This method returns an update count indicating how many rows in the table were affected by the query, so checking this return value is necessary to ensure the query was executed successfully.String sql = "INSERT INTO Users (username, password, fullname, email) VALUES (? In this case, method should return 1 to indicate one record was inserted.To keep it simple — but also show several different data types — I've created the following My SQL database table: create table users ( id int unsigned auto_increment not null, first_name varchar(32) not null, last_name varchar(32) not null, date_created timestamp default now(), is_admin boolean, num_points int, primary key (id) ); -- insert some sample records insert into users (first_name, last_name) values ('Fred', 'Flinstone'); insert into users (first_name, last_name) values ('Barney', 'Rubble'); A few of these fields are a little contrived, but I wanted to show several different data types in one table, so this is what I came up with.In particular, the field "num_points" is a little unusual.In turn, those design principles affect how you enter data.Remember these facts about database objects and design as you proceed.
An Access database is not a file in the same sense as a Microsoft Office Word 2007 document or a Microsoft Office Power Point 2007 slide deck.
Recommended Book: Getting Started with No SQL The following code snippet queries all records from the Users table and print out details for each record: Retrieves value of the second column in the current row, which is the username field.
