Create A/R distribution using IF...THEN or CASE

I am trying to write a query in Transact-SQL to create a user view in my SQL
database. I am trying to populate columns for each "aging" category (30, 60,
90, etc), so the correct age receives the amount due, but other columns are
zero. However, I can't find the correct CASE or IF...THEN syntax. It needs t
o
do something equal to the following:
If ServiceDateAge BETWEEN 0 AND 29 Then CurrentDue = PatientDue Else
CurrentDue = 0.
If ServiceDateAge BETWEEN 30 and 59 Then 30DayDue = PatientDue Else 30DayDue
= 0...
etc
I would be grateful for help...Thank you.Try using CASE expressions like the snippet below. See the Books Online for
more info.
SELECT
CASE WHEN ServiceDateAge BETWEEN 0 AND 29 THEN PatientDue ELSE 0 END AS
"CurrentDue",
CASE WHEN ServiceDateAge BETWEEN 30 AND 59 Then PatientDue ELSE 0 END AS
"30DayDue"
etc...
Hope this helps.

of using CASE to populate a quantity in a column (thought it may have been
there).

statement. It simply returns a single value conditionally so you need to
replicate the CASE expression. If you are using SQL 2000, you can
encapsulate CASE in a user-defined scalar function like the example below.
CREATE FUNCTION dbo.AgeAmount
(
LowAge int,
HighAge int,
Age int,
Value int
)
RETURNS int
AS
BEGIN
RETURN
CASE
WHEN @.Age BETWEEN @.LowAge AND @.HighAge THEN @.Value
ELSE 0
END
END
GO
SELECT
dbo.AgeAmount(0, 29, ServiceDateAge, PatientDue) AS "CurrentDue",
dbo.AgeAmount(30, 59, ServiceDateAge, PatientDue) AS "30DayDue",
dbo.AgeAmount(0, 29, ServiceDateAge, CurrentInsuranceDue) AS
"CurrentInsuranceDue"
etc..
Hope this helps.

OK I'm in business. However, I ran the script in Query Analyzer. It ran
successfully, but I could not find my function, even though I'm sure I was
accessing the correct database. So, I opened a new user defined function,
deleted the standard text and inserted your text. This saved with no errors
and I am using the function now. Thank you for introducing me to this
interesting area of SQL 2000.

CPU Distribution between Sql Server and OS

Hi,
I am a DBA for SQL server and I have a poduct to be tested for performance
with backend MSSQL Server 2005 developer edition. I have a machine of 8CPU's
and the senario is
the dataserver has to function for some big computations and data processing.
application is on .Net c# code also will be loaded on the same machine,
should also be scaleable with multiple users working on the app. and database
access.
My question is
1) Is there a guodeline for spliting the CPU's with MSSQL server and OS ( OS
and App)
2) Are any documented(cases) white papers on the same(resourse charing
between OS and sql server).
Please share you experiencies.
Thanks,
fellow DBA.

I don't know of any white papers, these things are not recommend to be on
the same machine; a general value would only be a starting point anyhow. You
should decide the configuration from the results of your load testing and
cover as many hardware combinations as possible to get the best results.
You can not use Developer Edition for a production system, if the hardware
you are testing on is not the same as the destination server you may only
have a general guideline to performance.
