control transaction duration

Hi guys,
can I control the duration of a transaction ?
Using ADO I can set a command timeout, but using T-SQL or
modifying some SQLserver parameter, can I set a sort
of timeout on a transaction and get the same result (i.e. prevent
a transaction from running too long) ?
Many thanks for your kind help

You can control max time you wait when you wait to be granted a lock. Check out SET LOCK_TIMEOUT.
However, you cannot set the max time you hold a transaction open or how long a query can run at the TSQL level
(ignoring the query governor), this has to be done in the client app (using ADO, ADO.NET of whatever API you
are using).

Context Change and Cursor

I have T-SQL code that is used to run utilities against a particular list of databases that are stored in a table. I have a cursor that gets the list of DBs from the sysdatabases table based on entries in a table in a specific database. The list of databases will vary from server to server, so I need to have it use variables rather than code the db names into the script.

declare @.DatabaseId char(8)

declare DatabaseLoop cursor for
select name from master..sysdatabases where name in
(select <column name> from <db name..table> )

open DatabaseLoop
fetch next from DatabaseLoop into @.DatabaseId
while (@.@.fetch_status <> -1)
begin

...

So far, the context has not mattered, for example - backup @.DatabaseID works fine within the cursor since the context doesn't need to change. The problem is that I want to run particular scripts that require the context to be changed to the database. But, of course, USE @.DatabaseID does not work inside the cursor.

So, is there another way to be able to run my script against multiple variables other than using a cursor?

I am not necessarily looking for you to write my code, but if someone could point me in the right direction, I would appreciate it.

I would suggest that you use dynamic SQL for this and you can use a use in there.

declare @.query varchar(8000) -- I am assuming 2000 since you

--used sysdatabases

set @.query = 'use ' + @.database + ' select * from sysobjects'

exec (@.query)

I know this works in 2005, and am pretty sure it worked in 2000

Edit: Sorry, sent the message from my phone and it did a terrible job with the formatting

Consuming result set from trigger in T-SQL

If I have a trigger that returns a result set, is there a way to consume
that result set from T-SQL?
E.G.
CREATE TABLE T
( id identity(1,1),
data varchar(10) )
CREATE TRIGGER mytrigger
ON T
AFTER INSERT
AS
SELECT id FROM inserted
-- This doesn't work:
-- SELECT * FROM (INSERT T(data) SELECT otherData FROM AnotherTable)
-- I can do this and consume the result set at the client though...
INSERT T(data) SELECT otherData FROM AnotherTable
thank you.No, AFAIK thats not possible. If you really, really wanna do this you could
store the resultset in XML in an extra table and query for.

separate operations in a stored proc? That way you can handle the result any
way you choose.

relationships within the schema, when you cannot use DRI actions. Do
the SELECT as a sepaarate statement.

Constant variables

Hi!
Is there a way to create constants (i.e. constant variables) in stored
procedures? Basically I'm looking for the T-SQL counterpart of Oracle
PL/SQL's
"x_var constant integer := 999;"-type declarations.
Thx,
AgostonHi!
I'm forwarding this because I couldn't find another way to avoid
multiposting once I have forgotten to cross-post to other groups. Sorry,
anyway.

>|||No. TSQL Programming doesnt have any keyword for constant variable.
but if you want to store constants, it is recommended to keep them in
separate table and read it in the TSQL block. one level of security you can
provide is not to allow anyone to update the constants table.
In sql world, constants are data values. like string literals, numeric and
decimal values.
