Predefined sort order

Hi
is there a way of sorting elements in a predefined order like
select * from currencies
order by ('eur', 'can' ,'yen', *)
so that eur, can,yen comes first and then the rest?
(without an sp)
greets mikeTry something like this:
select <columns>
,PrimarySortOrder
= case <currency column>
when 'eur' then 100
when 'can' then 200
when 'yen' then 300
else 999
end
from currencies
order by PrimarySortOrder
,<currency column>

You haven't provided DDL, so I'm going to make it up as I go along, you'll
have to edit to fit your database.
How about using CASE? Assuming the column to sort by is called currency:
SELECT * FROM currencies
ORDER BY
CASE WHEN currency = 'eur' THEN 1
ELSE WHEN currency = 'can' THEN 2
ELSE WHEN currency = 'yen' THEN 3
ELSE 4
END
If you end up having a long list of currencies to sort by this will end up
getting messy. You could do this using a joined table to make it much easier
to define a long list of currencies to sort by, and easily change the sort
order without changing your query.
CREATE TABLE [dbo].[currencysort] (
[currency] [varchar] (3) NOT NULL ,
[sort] [int] NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[currencysort] ADD
CONSTRAINT [PK_currencysort] PRIMARY KEY CLUSTERED
(
[currency]
) ON [PRIMARY]
GO
(I've been lazy and used the EM script tables wizard).
INSERT INTO currencysort VALUES('eur',1)
INSERT INTO currencysort VALUES('can',2)
INSERT INTO currencysort VALUES('yen',3)
Now, assuming that you have a field called currency in your currencies
table, you can do something like this:
SELECT currencies.*
FROM currencies LEFT JOIN currencysort ON currencies.currency =
currencysort.currency
ORDER BY COALESCE(currencysort.sort,99)
There are likely much more efficient ways to do this, but someone else can
come up with those :)
Dan|||create table #t
(
[id] int not null primary key,
col varchar(10)
)
insert into #t values (1,'dol')
insert into #t values (2,'rub')
insert into #t values (3,'can')
insert into #t values (4,'yen')
insert into #t values (5,'shek')
insert into #t values (6,'pnd')
insert into #t values (7,'krn')
insert into #t values (8,'eur')
--> order by ('eur', 'can' ,'yen', *)
select * from #t
order by
case when col = 'eur' then 2
when col = 'can' then 1
when col = 'yen' then 0
end desc

Predefined reports for Perfmon data

I have perfmon data collected in a sql database and now i would like to
display the data captured in the form of report.. But I dont really know how
to go about it ? Is there a pack or set of reports that are out there that I
could use and just plug it to the perfmon collection database ?
Thankshi there
