Creating star joins

The following should be added to Chapter 4 of the Adaptive Server IQ
Administration and Performance Guide
just after the figure that shows the
sales_order table in a star join.

You can create this table using the following commands:

CREATE TABLE "DBA"."sales_order"

(

"id" integer NOT NULL,

"cust_id" integer NOT NULL

REFERENCES "DBA"."customer" ("id")

UNENFORCED,

"order_date" datetime NOT NULL,

"fin_code_id" char(2) NULL

REFERENCES "DBA"."fin_code" ("code")

UNENFORCED,

"region" char(7) NULL,

"sales_rep" integer NOT NULL

REFERENCES "DBA"."employee" ("emp_id")

UNENFORCED,

PRIMARY KEY ("id"),

);
