Can CASE match more than once ?

Hi
I'm tring to write a statement to analyse what orders were open on the first
day of each month from a system and return one data set with the months
listed and all the orders open during that month. eg.
Mon Order_No
Jan 001
Jan 002
Jan 003
Feb 002
Feb 003
Feb 004
The orders all have an open and closed date, so I want to check for each
month if the first of the month falls between the open and closed date of
each order.
I've set up a dummy database for testing - what I'd like to know is whether
CASE statements be made to match more than once :
SELECT MyNewField =
CASE
WHEN data1 = 1 THEN 'Is One'
WHEN data1 > 1 then 'Not One'
end,
data2
FROM APW_Test
my table is as follows
data1
1
2
3
4
So I would hope to see one result for the number 1 (Is One) and two results
for the remaining numbers because they match both case statements. However,
CASE seems to match the first statement and then stop for each record.
Is there a way I can achieve the result I want fairly simply ?
Thanks in advance.
AndrewHi ... I made a mistake in my logic. What I meant was

> WHEN data1 = 1 THEN 'Is One'
> WHEN data1 > 0 then 'Greater Than Zero'
so I expect 1 to appear twice. All else the same.

you can simply use procedure/function to use if condition.
However post DDL,Sample data to help you better

CASE returns only the first match.|||Andrew,
It sounds to me like you need a JOIN operation, not a CASE expression.
Post the CREATE TABLE and INSERT statements for some specific
data if you want a more careful answer, but this might be close:
select data1, DisplayAnswer
from T join (
select 'equal 1' as TestCondition, 'Is One' as DisplayAnswer
union all
select 'above 1', 'Not One'
) C
on (
TestCondition = 'equal 1' and data1 = 1
) or (
TestCondition = 'above 1' and data1 > 1
)
If you select only from your 4-row table, with no other table
joined in, you cannot obtain a result that contains any row
more than once.

Hi Andrew,
You could use a calendar table or a table of integers to get this. I'll
give an example with a table of integers that's made up "on the fly".
You can expand it as needed, or make a real table of integers (as
explained on http://www.aspfaq.com/show.asp?id=2516).
DECLARE @.StartDate smalldatetime
,@.EndDate smalldatetime
SET @.StartDate = '20050101' -- Should be first of the month
SET @.EndDate = '20051201'
SELECT DATEADD(month, Numbers.n, @.StartDate) AS Mon,
Orders.Order_No
FROM Orders
INNER JOIN (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL
SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL
SELECT 9 UNION ALL SELECT 9 UNION ALL SELECT 10 UNION ALL
SELECT 11 UNION ALL SELECT 12 UNION ALL SELECT 13 UNION ALL
SELECT 14 UNION ALL SELECT 15) AS Numbers(n)
WHERE Orders.OpenDate < DATEADD(month, Numbers.n, @.StartDate)
AND Orders.CloseDate > DATEADD(month, Numbers.n, @.StartDate)
AND DATEADD(month, Numbers.n, @.StartDate) <= @.EndDate
ORDER BY Numbers.n, Orders.Order_No
Best, Hugo

Can .NET Application access SQL 2005 Express remotely?

I am tring to access the SQL 2005 Express which installed in remote machine. Front end app is on Visual Studio 2005. Try to connect SQL Express using the application Layer which is installed on the computer where SQL Express is installed. Could not fetch data from the SQL Express. What could be the problem?

With Regards,

hi,

SQLExpress installs by default disabling remote connections..

have a look at the resources listed by Arnie,
