Hi

I have a tables like below

TblA

ID(unique)---SessionID(unique)----Ref

TblB

VisitID(unique)---SessionID(Multiple)----Page--Pdcode

My question : How Do I bring all rows from TblB and matching single row from TblA (I have more than one sessionID in TblB and only one Unique SessionID in TblA).

The Select query I was using is

SELECT     PageViews.ID AS ID, PageDetailView.VisitID, PageViews.PageAccessed, PageDetailView.PageAccessed AS Expr1, PageViews.QueryString, 
                      PageDetailView.QueryString AS Expr2, PageViews.Referer, PageViews.SessionID, PageDetailView.SessionID AS Expr3, PageDetailView.PdtID, 
                      PageDetailView.Pcode, PageDetailView.CustID, PageDetailView.OrdTot, PageViews.[Date]
FROM         PageViews RIGHT OUTER JOIN
                      PageDetailView ON PageViews.SessionID = PageDetailView.SessionID
ORDER BY PageViews.ID DESC

just join them using the matching SessionID column. Or was your question to display the TblA information only once without repeating for each TblB row?

So how do you want to show the matching values from TblB? or are you interested in showing only one value from TblB (latest,earliest,random) ?

Hi I want All rows from TblB and single matching (matching by sessionID)row from TblA but not repeated rows from TblA. Sorting by TblB.ID Desc.

TblA has Unique SessionID and there is no duplicates
TblB Has Many SessionID

I am tring to create views first, then use asp.net to call views to display the tailored information about web stats, sales etc.

This is a presentation issue.
If you have one record in tblA and two records in tblB with same SessionID, you get row "rows" back from tblA because you match that row two times.

Just turn on "Suppress/hide duplicate values" in your report designer.

Hi

Thanks for the reply. I will try to log all session ID to one table. Need Some advice on the following.

1. I am going to create many "Views" from One table.
2. AM I ABLE TO USE "Procedures" for the "Views" ?

You can use procedures on your views. You use views in same manner as tables as views are nothing but virtual tables. Also you can create more than 1 view from a table.
