asp_web_howto thread: Help need on query


Message #1 by "Ryan vd Merwe" <ryan@8...> on Thu, 31 Oct 2002 11:19:09 +0200
Hi

My problem is as follows:

I need to display the articles that are not listed in table 2. so for example how do I display the articles that are not in table 2 
where nsID=1 (how do i display articles 1 and 4)?

hope this makes sense
Table structure is below.

table 1

      Table1 
      articleID number 
      articleTitle text 


represented table 1 looks like

      Table1 
      articleID articleTitle 
      1 Product launch 
      2 Latest sales fuigures 
      3 Annual Report 
      4 Year end function 



table 2

      Table2 
      articleID number 
      nsID number 



represented table 2 looks like:
      Table2 
      articleID nsID 
      2 1 
      3 1 
      4 2 
      2 2 



thanks in advance

Hi Ryan

You need to use a LEFT OUTER JOIN:

SELECT
	Table1.articleID,
      Table1.articleTitle,
	Table2.nsID
		FROM Table1
			LEFT OUTER JOIN Table2 ON Table1.articleID =3D Table2.articleID

Hi Joe

I have tried left outer join but it just displays all the listings in
table1.
