I recently ran into an issue when trying to use the AJAX toolkit rounded corners extender in conjunction with the modal pop-up extender. When I set the target of both extenders to the same panel, my popup was not showing up correctly (my popup was squished and wasn’t displaying any of the contents I had created). I found a great, easy to understand solution on this blog post: http://www.creativeui.com/2007/07/04/aspnet-ajax-creating-pretty-popups/.

 

Hopefully it will help any of you out there who might run into the same issue.

Updating a table with data from another table in the same database is something I find myself doing pretty frequently – I use this example quite a bit so I thought I’d post it for easy reference. It facilitates the updating of one table with data from another table, using a key relationship:

 

Take for example TableA with the following columns…

 

ModelId (PK)

CarName

VehicleDescription

CarSerialId

 

And TableB with the following columns…

 

MaintenanceId (PK)

ModelId (FK)

MaintenanceHist

OwnerName

CarDescription

 

If I wanted to update the CarDescription column in TableB with the data in the VehicleDescription column in Table A, joining on ModelId, this is how it would be done:

 

UPDATE [DatabaseName].[dbo].[TableB]

SET CarDescription = TableA.VehicleDescription

FROM TableB, TableA

WHERE TableB.ModelId = TableA.ModelId

 

 

]]>Using T-SQL 'TOP' Clause with Variableshttp://pinyination.squarespace.com/home/2008/12/18/using-t-sql-top-clause-with-variables.htmlAlyssa Biederman2008-12-18T22:14:32ZI’ve run into a few situations in which I needed to use a variable in a ‘TOP’

clause in a stored procedure. SQL Server won’t allow a variable to be used as

the top number of records to be selected:

 

(SqlServerError: Incorrect syntax near '@top'.).

 

Usually setting ROWCOUNT would be a good alternative, however I recently

ran into a situation in which this would not give me the intended results.

Here’s why: The stored procedure that was created used a TOP selection

criteria in a subselect – ROWCOUNT applies to the final result set of the query.

The Solution: By using the Row_Number() function, row numbers can be assigned

to items in the subselect. In this example, the subselect is numbering rows for the top

taxpayers in a tax region using

 

Row_Number() OVER (ORDER BY c.Total DESC) AS [RNumber]

 

The order by clause designates that the owner with the highest total will have a

row number of 1 and so on. In the containing query, it can be specified to only

show results for records with a row number less that the parameter passed to

the stored procedure.

 

@iNumRows INT

-- (This is our variable to hold the number of

-- Results the user wished to see)

 

SELECT e.nName, e.nAddress

FROM

   (SELECT Row_Number() OVER (ORDER BY c.Total DESC) AS [RNumber],

   SUM(c.Total) as Total, c.OwnerName

     FROM

     (SELECT DISTINCT b.OwnerName, a.land + a.Imp AS total,

     a.n1stTDP + a.n2ndTDP AS TotDelq

     FROM RM_TaxDuplicate a, RM_TaxDuplicateAddress b

     WHERE a.nTaxDistrict = 25006

     AND SUBSTRING(CAST(a.nLandUseCode AS VARCHAR(5)), 1, 1) = 5

     AND a.nParcelType = 400 AND a.nParcelId = b.ParcelId

     AND a.nFiscalYear = 2007) c

   GROUP BY c.OwnerName, c.Total, c.TotDelq) d,

   RM_TaxDuplicate e

WHERE e.nTaxDistrict = 67388 AND d.RNumber < @iNumRows

-- @iNumRows should be incremented by 1 when using the less than

-- comparison. (ie: if they want to see top 30, we would want

-- to look at rows less than 31)

AND g.OwnerName = d.OwnerName AND e.nFiscalYear = 2007

ORDER BY d.Total DESC, e.nOwnerName
