Steps to Creating Tables:
Using the Create Table Dialog
Expand the Contact DB connection node and note that there are several schema subnodes. The app schema is the only schema that applies to this tutorial. Right-click the APP node and choose Set as Default Schema.
Expand the APP node and note that there are three subfolders: Tables, Views and Procedures. Right-click the Tables node and choose Create Table to open the Create Table dialog box.
In the Table Name text field, type FRIENDS .
Click Add Column. The Add Column dialog box appears.
For Column Name, enter id . For Data Type, select INTEGER from the drop-down list.
Under Constraints, select the Primary Key checkbox to specify that this column is the primary key for your table. All tables found in relational databases must contain a primary key. Note that when you select the Primary Key check box, the Index and Unique check boxes are also automatically selected and the Null check box is deselected. This is because primary keys are used to identify a unique row in the database, and by default are used as the table index. Because all rows must be identified, primary keys cannot contain a Null value.
