I'm still using it cause a Microsoft Certified SQL professional show me the
tracing and performance of "LEFT/RIGHT/OUTHER/INNER JOIN and *=/=/=*/*=*
and the last one is better and faster.

Why? Not a challenge, but a question. Using *= or (+) always seemed,
at least to me, quicker, easier, and easier to read afterward.
Now, I admit that I mostly got into the habit because, until fairly
recently, I was stuck on an Oracle platform that was too old to use
INNER JOIN/LEFT JOIN, but how much does it really matter?

This is the OLD way to perform a join - it should be avoided.

SELECT r.eventID, d.title
FROM Events r,EventDescription d
WHERE d.eventID *= r.eventID

You are using an INNER JOIN - you need to use a LEFT JOIN I believe.
SELECT r.eventID, d.title
FROM Events r
LEFT JOIN EventDescription d
ON WHERE d.eventID = r.eventID

SQL Server 7.
<cfquery name="q1" datasource="newStuff">
SELECT r.eventID, d.title
FROM Events r,
EventDescription d
WHERE d.eventID = r.eventID
</cfquery>
This query only returns rows from "Events" table that have eventID
present in "EventDescription" table. I need to return ALL rows from
Events table whether thay have a description or not.
As ever, thanks in advance,
Dave
