I am new to creating SQL queries and need some help.
I am trying to query from three tables.
1 - A table with a list of Drawings (DRAWINGS)
2 - A table with the Revision history of the Drawings (REVISIONS)
3 - A table with the list of Projects (WRI_SITE_PRJS)
The result I am looking for:
Name of Drawing (I want to return the drawings that don't have a revision as well)
Last Drawing Revision
Date of Revision
Project that the drawing belongs on
The below query I created in access and the result was exactly what I was expecting.
SELECT DRAWINGLIST.NAM E, DRAWINGLIST.WRI _DESCRIPTION AS [Drawing Title], LastRev.LastOfR EVISIONNAME AS Rev, LastDate.LastOf REVISIONDATE AS [Rev Date], WRI_SITE_PRJS.T ITLE AS Project
FROM LastRev RIGHT JOIN (LastDate RIGHT JOIN (DRAWINGLIST INNER JOIN WRI_SITE_PRJS ON DRAWINGLIST.WPR JID = WRI_SITE_PRJS.W PRJID) ON LastDate.NAME = DRAWINGLIST.NAM E) ON LastRev.NAME = DRAWINGLIST.NAM E
ORDER BY DRAWINGLIST.NAM E;
I tried getting the same result in SQL and find that I can't GROUP BY the LAST date in a table. The result I'm getting is all the revisions for the drawing.
My question is: How do I query for the LAST date or revision in a table.
I'm using Microsoft SQL Server 2003
Some help is greatly appreciated.

Use Max() on the date column and group by everything else.

Hi there,
I'm sort of new with doing much record manipulation with queries. Up

results. This works fine but tends to get very, very slow as the
number of records grows - somewhere in the number of 5,000,000. I
imagine queries are much faster but am not quite sure if queries will
do the trick.

I have a table in an Access 2000 .mdb file, and I've run into something odd

This particular table, called tblMembershipInfo, has fields/columns as
