For details on creating tables, refer to your DBMS SQL reference for specifics. 0 - Production on Thu Jun 6 18:35:52 2002 SQL> create table MyEmployees ( 2 id INT PRIMARY KEY, 3 firstName VARCHAR(20), 4 lastName VARCHAR(20), 5 title VARCHAR(20), 6 salary INT 7 ); Table created. SQL> describe MyEmployees; Name Null? qxd 20 8/11/05 4:05 PM Page 20 CHAPTER 1 ■ INTRODUCING JDBC In general, in real project development, you define a SQL script that defines all the tables, views, and indexes. But it is also possible to create a table with a Java program.
A table/view is a container comprised of rows/records. • A row/record is a container comprised of columns. • A column is a single data item having a name, type, and value. • A database stores all its data inside tables, with nothing else. All operations on data take place on the tables themselves or produce additional tables as the result. 1-5. What Is ODBC? Open Database Connectivity (ODBC) is a programming interface from Microsoft that provides a common language for Windows applications to access databases on a network.
After I cover these steps in the following sections, I will discuss the JDBC program in detail. Step 1: Creating a Database or Using an Existing Database For this step, you can use an existing Microsoft Access database called northwind; Figure 1-7 shows northwind in a Windows XP environment. Figure 1-7. qxd 8/11/05 4:05 PM Page 11 CHAPTER 1 ■ INTRODUCING JDBC Step 2: Registering the Database Use the Microsoft ODBC Data Source Administrator to register your database, as shown in Figure 1-8. ) Figure 1-8.
