Aug 22, 2005Should i create only one trigger for each table and put all the table functionality in that one trigger?
For example: tr_tblCategory, tr_tblQuestion, tr_tblAnswer
Or should i create a different trigger for each different function on that table?
For example: trReviseDate, trDoThis, trDoThat, trVerifyThis
Is there a better practice in this area?
What do you typically do?
Thanks!

Jan 25, 2008I do not know if I am in the proper thread, if not thnaks to let me know where to post it..
I have a runing table name CURENTALARM which strore different alarm information.
This table has a Column named STATUS.. When the new inserted rows ocurrs and STATUS =1, then I need to copy that row in a new table name STATUSLOG...
For that I have created a trigger for table CURENTALARM and then do proper commands to insert to other table.
I am using the inserted table in my trigger to fetch last inserted rows.
The question I have is that how to guaranty that each inserted row will fire the triggers properly...
What I mean is that in case I have 2 rows which gets inserted within less than a second in time interval, does the triggers will be able to do its job and proceed properly inserted row or is there a situation that when rows gets inserted too fast, the triger might miss some of them ?
If this is the case how to handl that case
thanks for your reply

A Simple Trigger That Doesn't Work
Jan 18, 2006Hi all, I have a problem with this trigger. It seams to be very simple, but it doesn't work...
I created a trigger on a table and I would want that this one updates a field of a table on a diffrent DB (Intranet). When I test it normally (a real situation), it doesn't work, but when I do an explicit update ("UPDATE AccesCard SET LastMove = getDate();" by example) it works.
If anyone could help me, I would appreciate.
NB: Is there a special way, in a trigger, to update a table when the table to update is on another BD ?
Francois
This is the trigger:
------------------------------------------------------------
ALTER TRIGGER UStatus
ON AccesCard
AFTER UPDATE, INSERT
AS
DECLARE @noPerson int
SET NOCOUNT OFF
IF UPDATE(LastMove)
BEGIN
SELECT @noPerson = Person FROM INSERTED
UPDATE Intranet.dbo._Users SET Intranet.dbo._Users.status = 1 WHERE personNo = @noPerson;
END
SET NOCOUNT ON

Request Help Writing A Simple Trigger!
Feb 26, 2008Experts: Please assist with coding a trigger for a SQL Server 2005 .NET application.
Here's the scenario:
Suppose there are tables MEMBERS, ACTIVITY, and HEADCOUNT that look like this:
MEMBER
member_id (int)
member_name (varchar(50))
...etc
ACTIVITY
activity_id (int)
activity_name (varchar(50))
...etc
HEADCOUNT
headcount_id (int)
member_id (int)
activity_id (int)
...etc
Suppose also that the ACTIVITY table is already populated with several records, say with activity_id = 1, 2, and 3.
OBJECTIVE: When a new member record is added to MEMBER, say member_id 10, insert one record in the HEADCOUNT table for EACH activity in ACTIVITY for that member. Thus, if member #10 is added to MEMBER, then the trigger (or some other mechanism) would add the following records to HEADCOUNT (which, say, already has 30 records):
headcount_id member_id activity_id
31 10 1
32 10 2
33 10 3
I've been advised that a trigger should do the trick for this, but as I'm totally new to SQL, I'll need some help. I'm guessing some iterating SQL command language might be required, but as I'm new to SQL, I don't know how to proceed.
Note that I'm building an ASP.NET application based on VB, and so records will be added to MEMBER through a tableadapter INSERT command. (Though I suspect this has no bearing on trigger behavior.)
Much obliged for your assistance.

Using ADO AddNew And My Simple Trigger Won't Execute
May 8, 2006Hi,We have been using ADO and the AddNew method for a long time as a meansto add records to the database. It has always worked fine - no problem.But - we recently started using INSERT triggers that simply call a fewstored procs (they're actually SSNS stored procs that send new eventinfo to notification services). Anyway, these triggers do not seem tofire at all! If I execute an insert command manually from QueryAnalyser, no problems. But the trigger does not fire at all from myapplication!Does anyone know why this could be? For info, my connection string usedby the ADO connection object looks like this: Provider=SQLOLEDB.1;DataSource=XXX;Initial Catalog=YYYAnd my AddRecord ADO code looks like this:With rs.Open sSQL, ConnectionString, adOpenKeyset, adLockOptimistic,adCmdTable And adExecuteNoRecords.AddNewAm I mnissing something obvious here?

CLR-Based Trigger? Recursive Trigger? Common Table Expression?
Nov 14, 2006Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

Simple Join Not So Simple
Feb 21, 2007I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.
Simple Join Not So Simple
Aug 19, 2006Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks

I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.

Trigger Doesn't Log Into The Audit Table If The Column Of Table Has Trigger On Is Null
Jan 23, 2008
Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
Thanks,
leo
This All Seemed Simple Enough...
Mar 24, 2007...when I started this endeavor.
I have a previously developed Lotus Notes App. The idea was simple; as
I am sefl taught on Lotus Script, I figured I'd be able to stumble my
way through VB.Well,
it started OK. I used VB Express to get familiar with the stuff, but
decided to go with a full version of VS 2005 and try and get this thing
properly developed as a web app. I purchased several reference books
etc., and have become relatively familiar with the forums here.First
issue I have is that I simply want to use code to update or add records
to an SQL DB. I know about datagridview etc., but I want to update the
DB using forms, not the tabular view those controls provide. I thought
it would be relatively straight forward, but found my ignorance runs
deeper than I thought. When I tried to do so I am finding I am not
really clear on where to make declarations etc. in the web app. If anyone could point me in the right direction that would be great. The
issue with searching these forums is most posts deal with datagridview
or something similar.I have spent a ton of time trying to find relevant
posts or articles, but have had no luck yet.Again, all Ireally
need is a nudge in the right direction. I am more than willing to plod
through reference materials or articles/posts to find what I need to
know, I just can't find where to even start on the info I need. Regards, Joe
