COMMIT WORK;

The following SQL statement performs the query and displays a very small report. This query uses a join of 3 tables to list quantity and price for each item of an order. A basic introduction to the report generation capabilities provided by the iSQL Utility is shown in the form of the Column, Format and Heading syntax.

COLUMN cm_name FORMAT "A15" heading "NAME"

COLUMN oi_quantity FORMAT "A10" heading "QTY"

COLUMN im_price FORMAT "$A10" heading "PRICE"

SELECT custmast.cm_name,

orderitems.oi_quantity, itemmast.im_price

FROM custmast,

orderitems,

itemmast, orderlist

WHERE orderlist.ol_custnum

= custmast.cm_custnum AND

orderlist.ol_ordernum

= orderitems.oi_ordernum AND

orderitems.oi_itemnum

= itemmast.im_itemnum

ORDER BY orderlist.ol_custnum;

The report will appear as follows:

2.2.4Done

When a client application has completed operations with the server, it must release resources by disconnecting from the data- base. iSQL is an application that provides an interface for inter- active SQL. It may not be explicit but a connection is made with the server when the isql tool is launched. Likewise, a disconnect occurs when the isql tool is exited.

Below is the interactive SQL for DONE:

ISQL> quit

This will return the process back to a regular command line prompt.
