Need Help With Trigger Sql Server 2005

Oct 16, 2006

I am trying to create this trigger

CREATE TRIGGER User_Insert ON aspnet_users AFTER UPDATE AS
IF UPDATE (UserId)
insert into users (aspnet_user_id, username)
select au.userid, au.username
from aspnet_users au
where au.userid != users.aspnet_user_id;

Whenever the aspnet_users table has a new user added I want the Userid and username fields from that table inserted into the
the aspnet_user_id and username fileds of the users table.

when creating the trigger I get the following error..

Msg 4104, Level 16, State 1, Procedure User_Insert, Line 3

(SQL Server 2005) Instead Of Delete Trigger

May 31, 2006

Hi,

I simply need a trigger to delete some datasets from a view but have some trouble writing an adequate trigger. Here is my attempt:

Use myDB;
Go
CREATE TRIGGER IO_Trig_Del_myView ON myView
INSTEAD OF Delete
AS
BEGIN
SET NOCOUNT ON
-- Check for dataset, if present delete.
IF (EXISTS (SELECT Z.[myPk]
FROM myTable t, deleted
WHERE t.[myPk] = deleted.[myPk]))
Delete From myTable
Where myTable.[myPk] = deleted.[myPk]...

This causes the following failure:

Msg 4104, Level 16, State 1, Procedure IO_Trig_Del_myView, Line 11
The multi-part identifier "deleted.myPK" could not be bound.

Can somebody explain the reason to me? myPk is part of the View I created. Since I do have three tables in myView so I get that message three times, once per table.

SQL Server 2005 Query/trigger/function (whatever It Is That I Need)

Dec 8, 2006

Hey guys maybe you can help me out, been trying to figure this one out all day at work. I know how to use columns in a table to calculate another column in that same table. But I need to do some math on columns from a totally seperate table. Here is my scenario
 table 1 = stock table
 table 2 = Purchase order table
 in table 2 there are line items that have ordered quantities for parts that we have ordered
 in table 1 under each part number is a field for "quantity on order"
I need to compute the "quantity on order" in table 1 by summing all of the quantities in table 2 where the partnumber = the partnumber from table 1
 
quantity on order (table 1) = sum of all quantities (table 2) where the part numbers match
so for part number 516 i have this
 
table 2
poNumber             partNumber                 quantity
1                             516                             1
2                             516                             12
3                             516                             4
 
table 1
partNumber            inStock              onOrder
516                          0                        17(this is what i am trying to figure out how to compute)
 
any help on this qould be appreciated. I would like the database to automatically do this itself if at all possible.

Possible Trigger Problem SQL Server 2005 Express

Apr 7, 2008

 Hey guys,

I have a problem regarding (if it’s the
right way to go about it) triggers in SQL Server 2005 Express. I have already finished
my application but wanted to add this in. My system is a shipping system which
allows users to add data about ships, orders etc. In order for a order to be “put
on� a ship I have created a form which first allows users to select what order
and what ship and then creates a new entry on a table called OrdersonShip. What
I would like my code to do is first check that there is space on the ship (Each
ship has a maxCargo and a currentCargo) and then when the new entry on the
OrdersonShip table is produced I would like the numberofitems field on the
order to be associated with the ship to be added to the currentCargo on the
ship table. How would I go about this?

 Many
thanks for any help you can give me.

Peter

Design Question, Trigger Or SP [SQL Server 2005]

May 24, 2008



[SQL Server 2005]



In our system we keep track on all changes that are made by the users.

This means that posts is never deleted, only marked as not "active".

Each table has a SP who takes care of the INSERT/UPDATE.

This SP also calls another SP, which actually does the "inactive" marking of the post.

The question is:

Would it be better (or worse) to have a TRIGGER taking care of this instead?

Occasionally there are data inserted at the "exact" same time (different input sources).
Sometimes there can be a quite heavy workload on the INSERT.

if service broker is not an option, how can the trigger and sp(s) called by our trigger act asynchronously to the event that fired the trigger in the first place. We are more concerned with the original event being committed than the actions that follow via the trigger.

Email Trigger In SQL 2005

Jun 2, 2006

I am new to developing as will be evident from this post. Your help will be greatly appreciated.

I am developing an intranet for our company using ASP.NET with a SQL backend. I am currently working on a suggestion box form.

I would like to have an email sent to specific persons when a new entry is made in the suggestion table. I have been able to configure the trigger and generate the email (This was easy). Formatting the email has proven more difficult to resolve.

The format I would like is somewhat as follows:

F_NAME L_NAME submitted the following suggestion:

IDEA

BENEFIT

APPROVE | DECLINE

The items in RED are columns in the table and the Blue Underlines are hyperlinks to change the Status column in the table.

How can I generate the email to contain the data from the inserted record and in the above format.

Being new at this I only now how to send a static email advising that the entry has been made.

Any help creating the dynamic email form for this trigger will be greatly appreciated.

Lastly, what books are most helpful for SQL, ASP.NET, and VBScript referencing and examples?

Thanks

Sql 2005 Trigger Insert And Dbmail

Apr 23, 2008

I have a stored proc that inserts records into a table, gets the identity, and uses that identity on a .net webpage. The page retrieves that identity key and processes some stuff on the page.

Everything was working fine until I tried to enable sql mail with triggers. I wanted to double-check some stuff, so I requested an sql email be sent whenever an insert occurs on the table above. Here's what I think is happening --- please correct and/or help me out with a work around?

I use the stored proc to insert a record.
I select the @@identity.
The trigger fires but uses select to retrieve the latest insert - thereby replacing the @@identity number returned to the page?

If this is true, could I do something like the following in the original stored proc? Is this a good idea or bad idea?

BEGIN
Declare @myID as int, @myBody1 as varChar(200)
Set @myID=0
INSERT INTO table (fields) VALUES (@PID, more stuff);
Set @myID = SELECT @@IDENTITY As [Identity];
If @myID<>0
Begin
Set @body1='<br />pid=' + more stuff.....
Exec msdb.dbo.sp_send_dbmail
@profile_name='profileName',
@recipients='email@email.com',
@subject='Temp History Insert',
@body=@body1,
@body_format= 'HTML' ;
End

Why This Trigger Doesn't Work In Sql 2005

Mar 28, 2008

hi eveyrone,

I have an after insert trigger that works in sql2000 but not in sql2005. Can you please help me!!

CREATE trigger dbo.trUPS_tbl_I
on dbo.UPS_tbl
After Insert --For insert
as
declare @Tracking varchar(800),
@UPSID varchar(10),
@Cmmd varchar(800)

select @UPSID = cast(inserted.UPSID as varchar)
from inserted

commit

set @Cmmd = 'c:TasksUpdTrackingUpdateTrackingCS ' + @UPSID + ' ' + 'UPS1'
EXEC master.dbo.xp_cmdshell @Cmmd


The UpdateTrackingCS program will call a stored procedure to get the inserted data and update other databases. And the reason to put the commit statement in sql2000 is to have sql commit the transaction, so the store procedure in UpdateTrackingCS can query thtat inserted records.

When I use the same code in SQL2005, no matter what I do the UpdateTrackingCS program cannot query the data by the UPSID. It always says record not found.

I have tried to change commit to begin trans ... commit trans. But nothing works. Please help!

Thanks in advance.

Replication Trigger Problem (SQL 2005): Assistance Please

Jun 5, 2006

Our company is wanting to replicate a bunch of data down from our central server to tablet PC's. We really do not have anyone on staff with solid experience in replication, and have hit an error that we cannot seem to find any information whatsoever on.

Here is the problem:

When setting up a publication to replicate certain tables, we stop being able to do any updates on the tables. After some research, we were able to narrow the problem into the msrepl triggers the publication places on the table. In the update trigger of the table, the following line is being placed by SQL Server:

execute sp_mapdown_bitmap 0x0000000040, @bm output

The sp_mapdown_bitmap call, passes through to a xp_mapdown_bitmap call (limited documentation I have found is it is suppose to be an extended stored procedure), which if I try to manually execute, does not exist on the server (Logged in as SA the entire time).

Commenting out that line in the replication stored procedures corrects the problem. However obviously we do not want to manually do that everytime we create a publication, and we have no idea what negative impacts may occur because of it.

We are getting this behavior on several SQL Server 2005's...

Additional notes on the environment:

-CLR Triggers written in VB, on most tables performing application functions

-SQL Server 2005 SP1 is on the servers, and SQL Server 2005 Express Edition is on the tablets.

-Again this problem only exists on some tables in the database.



Any assistance would be greatly appreciated.

Trigger Work In VS Explorer - Not In Debug App - SQL Express 2005

May 6, 2008

OK I am really going nuts here. I have a trigger that will work if I insert a row using SQL MGMT Studio or VS DB explorer, but it will not insert using the tableadapter.update() command.

What is also strange is that I have to execute the query in the VS DB Explorer or SSMSE to get them to fill in the default values (trigger).

No matter what they don't work in the debug application:

Below is the trigger:



Code Snippet

ALTER TRIGGER [dbo].[weight_train_log_InsertTrigger]

CLR-Based Trigger? Recursive Trigger? Common Table Expression?

Nov 14, 2006

Hey,

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.
