I don't think this is possible either.

The only solution I can see is using a cursor to loop through all the possible groups. You can use the syntax from 'Tame...

Depends on what the types of columns are.

One solution is setting a database wide parameter :

sp_dboption 'database', 'concat null yields null', 'FALSE'

Or you can use the ISNULL function as in

col001...

You can use the following statement.

select max(number) from sysobjects o, syscomments c where o.name = 'mySP' and o.id = c.id

If the fields are not strings

SELECT cost FROM table

WHERE low < 10.00 and high > 10.00

Are the fields strings?

Then it might be necessary to cast to floats.

SELECT cost FROM table

WHERE...

Never thought of solving this problem using only a single table.

Typically, I opt for adding a 'history' table in which the non-active records get archived. But this becomes a hassle...

Can you post the table definitions?

You could use :

select v.vehicle_id, u.property, u.value

from vehicles v,

(select vehicle_id, 'chain', chain from vehicles

UNION

select vehicle_id, 'spacing', spacing from vehicles

UNION

select vehicle_id, 'teeth', teeth from vehicles

) u

where v.vehicle_id = u.vehicle_id

Same here.

We try to add a prefix to 'all' the objects in our database, to indicate the owner-module of the object.

Check the articles 'Tame Those Strings'.

One article (part 4) is about numeric conversions, and should get you pointed in the right direction :

http://qa.sqlservercentral.com/columnists/sjones/20010422115809_1.asp

Try this :

CREATE TRIGGER ClientUpdatesTrigger ON Table1

FOR UPDATE

AS

DECLARE @MyID nvarchar(50)

if exists(select id from inserted where status = 'Taken')

insert into testtrig2 (id)

...

How did you detach the file? (Same server, other server, what version of SQL Server, ...)

Do you have any reason to be suspicious about file corruption? (E.g. disk crash)?

Good point. The same questions do return on a regular basis.

A FAQ might be a good thing for certain questions. But, imho, that won't solve the *real* problem.

People should search...

I can see no reason why the trigger is fired again. Some tests here revealed no problem...

Can you post your trigger's code

You can also just use the IsNull function as in :

SELECT IsNull(F1,F2) F11, IsNull(F2,F1) F22

FROM #Test1

If possible at all, you should try to avoid the cursor loop. This is probably a greater cost than executing the query itself. You can test this, just by timing...
