Dear members,
Hello, a pleasant day to everyone.
I would want to ask help about this query that I need for reporting.
Let’s for example I have a database named DBMain, and I want to combine two tables by means of their key named InvTrackNo, eventually here is the query:

SELECT 
       A.ConsInvNumber AS [Consolidated Invoice No],
       A.InvTrackNo AS [Invoice TrackNo],
       B.SaleOrderNo AS [Sales OrderNo],
       B.OrderLine AS [Sales Order LineNo],
       A.CtrlNo
	   
FROM DBMain.dbo.ConsInvoiceDetail AS A  INNER JOIN
     DBMain.dbo.IndInvDetail AS B ON A.InvTrackNo = B.InvTrackNo
WHERE A.ConsInvNumber=980029768

And here is the output of my main query:

Consolidated InvoiceNo	    Invoice TrackNo	Sales OrderNo	   Sales Order LineNo	CtrlNo
980029768	            0901164982	    	162194751		 100		407633405
980029768		    0901164982	     	162194751		 200		407633405
980029768		    0901164982	     	162194751		100		407633405
980029768		    0901164982	    	162194751		200		407633405
980029768		    0901192336	    	161891209	       40		0
980029768		    0901192337		161891209		100		0
980029768		    0901192338		161891209		160		0
980029768	            0901204388		162044081		100		406488527
980029768		    0901204389		162044081		200		406488589

I noticed that some Control Number (A.CtrlNo) are zeros, my superior said I should look for the archive table and somehow “combine” them to this first query.

I tried to query first the archive table named OrderSummaryArchive that is located in a different database named DBArchive:

SELECT CtrlNo, 
         SalesOrderNo, 
         SalesOrderLineNo 
FROM OrderSummaryArchive 
WHERE SalesOrderNo = 161891209

And here is the output of my second query:

CtrlNo	  SalesOrderNo    SalesOrderLineNo
405290666   161891209	       20
405290666   161891209	       40
405290669   161891209          60
405290669   161891209          80
405290669   161891209	      100
405290674   161891209         120
405290674   161891209	      140
405290674   161891209	      160

As you can see, the highlighted result will complete my first query, I just do not how how to combine them if the second table is in another database, and how to check the appropriate CtrlNo for each record.

My expected result would be:

ConsInvoiceNo      InvoiceTrackNo	Sales OrderNo	   Sales Order LineNo	CtrlNo     CameFromArchive
980029768	   0901164982	    162194751		       100		407633405        0
980029768	   0901164982	    162194751		       200		407633405        0
980029768	   0901164982	    162194751		       100		407633405        0
980029768	   0901164982	    162194751		       200		407633405        0
980029768	   0901192336	    161891209		       40		405290666        1
980029768	   0901192337	    161891209		       100		405290669        1
980029768	   0901192338	    161891209		       160		405290674        1
980029768	   0901204388       162044081		       100		406488527        0
980029768	   0901204389	    162044081		       200		406488589        0

The report should include an additional column called CameFromArchive so that the database administrator would determine what CtrlNo came from the archive table (0-NO 1-YES).

I hope someone could help me fix my first query. Thank you.

Respectfully Yours,

Mark Squall

This is somewhat of a shot in the dark because we don't have ddl or sample data to work with.

SELECT 
       A.ConsInvNumber AS [Consolidated Invoice No],
       A.InvTrackNo AS [Invoice TrackNo],
       B.SaleOrderNo AS [Sales OrderNo],
       B.OrderLine AS [Sales Order LineNo],
       case when A.CtrlNo = 0 then osa.CtrlNo else a.CtrlNo end as CtrlNo	   
FROM DBMain.dbo.ConsInvoiceDetail AS A  INNER JOIN
     DBMain.dbo.IndInvDetail AS B ON A.InvTrackNo = B.InvTrackNo
Left Join (select top 1 CtrlNo from DBArchive.dbo.OrderSummaryArchive where SalesOrderNo = B.SaleOrderNo) osa
WHERE A.ConsInvNumber=980029768

I would suggest that when aliasing your tables you don't use A, B, C. Instead use some sort of abbreviation of the table name. It makes debugging a lot easier and anybody looking at your code doesn't have to scratch out their eyeballs trying to figure out which table certain columns come from.

Hello Sean. Thank you for the sample query, it works just fine (with some minor modifications). Awesome! Smile

I apologize to you (and to the readers) for making my aliases so short, actually I am just in a "hurry" that is why I used short aliases. In my query here, I (really) used full table abbreviation. (silly me). Crazy

Just one last thing, how would I add an additional column called CameFromArchive so that the database administrator would determine what CtrlNo came from the archive table (0-NO 1-YES)?

Thank you so much and more power!

Respectfully Yours,

Mark Squall

marksquall (1/14/2013Just one last thing, how would I add an additional column called CameFromArchive so that the database administrator would determine what CtrlNo came from the archive table (0-NO 1-YES)?

I think you can use a case just like the one that was allready included in the query posted by Sean, like so :

SELECT 
       A.ConsInvNumber AS [Consolidated Invoice No],
       A.InvTrackNo AS [Invoice TrackNo],
       B.SaleOrderNo AS [Sales OrderNo],
       B.OrderLine AS [Sales Order LineNo],
       case when A.CtrlNo = 0 then osa.CtrlNo else a.CtrlNo end as CtrlNo,	
       case when OSA.CtrlNo is NULL then 'No' else 'Yes' end as CameFromArchive
FROM DBMain.dbo.ConsInvoiceDetail AS A  INNER JOIN
     DBMain.dbo.IndInvDetail AS B ON A.InvTrackNo = B.InvTrackNo
Left Join (select top 1 CtrlNo from DBArchive.dbo.OrderSummaryArchive where SalesOrderNo = B.SaleOrderNo) osa
WHERE A.ConsInvNumber=980029768

EDIT: forgot a comma

Hello Geomorian. That was really cool. I am thinking it has be another technique, like for example, using a variable (BIT type) to set to either 1 or 0, then "convert" it to "YES" or "NO". (I guess I am just making my life too hard, silly me.). But for the record, is this possible? If yes, can someone give a little example?

Well anyway, this is straight to the point, and it is awesome! Cool

Thank you Geomorian and Sean Lange. Smile

Warm regards,

Mark Squall
