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.
Trouble With Update Trigger Modifying Table Which Fired Trigger

Create Trigger Help?
Sep 14, 2004I have a table that has a number of data fields,I need to be able to capture datatime when the date field was entered or entered value changed.I was told I need to create a trigger on that table that contains all the fields.
I have seen the syntax for creating triggers, and read some documentation but I am still in the dark as how to create what I need to.
I was hoping to see if somebody had a similar example or an advice, anything is more than what I have at the moment.
CREATE TRIGGER NotifyDateFieldUpdates
ON RelocateeRemovalist
For INSERT, UPDATE, DELETE
AS
DECLARE @RemovalistNumber VARCHAR(200)
DECLARE @RelocateID INT
/*InspectionDate */
DECLARE getInsp CURSOR FOR SELECT RelocateID,RemovalistNumber
FROM INSERTED a LEFT JOIN DELETED b ON (a.RemovalistNumber=b.RemovalistNumber and a.RelocateID=b.RelocateID)
WHERE a.InspectionDate IS NOT NULL AND b.InspectionDate IS NULL
OPEN getInsp
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber
WHILE (@@FETCH_STATUS <> -1)
BEGIN
INSERT INTO RelocateeRemovalistFieldEntry(RElocateID, RemovalistID)SELECT
RelocateID,RemovalistID FROM INSERTED a LEFT JOIN RelocateeRemovalistFieldEntry b ON
(a.RelocateID=b.RelocateID AND a.RemovalistNumber=b.RemovalistNumber)WHERE b.RElocateID is null
UPDATE RelocateeRemovalistFieldEntry SET InspectionDateDateTime=GETDATE()
WHERE RelocateID=@RelocateID aND RemovalistNumber=@RemovalistNumber
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber
END
DEALLOCATE getInsp
GO
This is what I was able to come up with so far,but when i check the syntax it gives me an error "Ambiguous column name "RelocateID" and "Ambiguous column name "RemovalistNumber" I don't know what is it trying to tell me here and couldn't find much help.
Regards and thanks

May 9, 2008i do have my 'Product' TABLE IN DATABASE 'ABC'

Now i want TO CREATE TRIGGER such that every updation in Product TABLE will UPDATE the appropriate record IN Product_Mst
FOR example IF i fire below query IN ABC Database
UPDATE Product
SET PRODUCT_DESC = 'Available' WHERE Product_Code = 6001
Then the OUTPUT OF the Product_Mst shoub be..
Product_Mst OUTPUT
PROD_CODE Prod_Ver PROD_TYPE PROD_DESC PROD_ID PROD_GRP_CODE
6001 0 computer NULL ENVD 14
6001 1 computer NULL ENVD 14

6003 0 mouse NULL ENVD 14
6004 0 cables NULL ENVD 14
6005 0 processor NULL ENVD 14
Means i want to increment the version by 1 and Insert that records into Product_Mst Table at every updation.
I hope i am clear with my question.

Jan 10, 2008Hi folks,
I have created a trigger that I can enter and works great from the sqlcmd terminal. When I try to submit the same query in a .NET project I get an error that "Create Trigger must be the first statement in a batch". The Create trigger is submitted by itself through the sqlcommand.executenonquery() method.
I am trying to create a database for a project but the only thing that I can't seem to get working is submitting this trigger.

Aug 16, 2000Hi there,
Once in a while, I find down there are some missing objects in production database. Because we share the sa password with couple of developers, therefore, it's hard find down who did it. So, I try to create a trigger in sysobjects table to prevent this problem, however, I keep getting the error message "error 229: create trigger permission denied on object 'sysobjects'"
although I log in using sa. Can someone give me some suggestions how to prevent this from happening beside using trace profiler and also why do I get the denied message when create trigger on sysobject even with sa login.

Aug 17, 2007Hi,
I have the following situation.
I have one table named as "Order", and other table as "Shipment". Now, I want to check if one column name "Status" in the "Ă–rder" table has been changed (when it becomes status = 7) then I need to insert records in "Shipment" table.

Create Trigger For Relationship
Mar 19, 2008Hi,
I need help in creating a trigger before delete. The trigger should be in such a way that it should display a message, if there is any relationship with other table.
For example I have a table with employee details which have empid as primary key. I have another table with employee salary details where empid is foreign key. The trigger should check the relationship with these two tables. If I try to delete an emploeyee from employee details table and if there is a relationship of that employee with the salary table then the trigger should print a message. If there is no relationship then the trigger should perform the deletion.
I want to create a trigger like this.
Please help!!!!!!!!!!!!!!!!
How To Create A Trigger To Update A Field
Aug 2, 2007Hi -
I know my way around VS but I am just exploring "advanced" SQL Server 2005 and have run into a challenge which I think a trigger could solve, but I am not sure and also don't know how to set that up. So any help or links to tutorials are highly appreciated.
Here is the challenge: I have a table with a number of fields, among them RequestID (bigint) and Booktime (datetime). What I would like to happen is whenever someone writes a value different from NULL into RequestID, Booktime gets set to the current timestamp. When RequestID gets set to NULL, Booktime gets set to NULL.
Is there a way to do this with a trigger (or an otherwise elegant way)?
Thanks in advance for ANY help or ideas.

Create Trigger To Use AFTER DataAdapter.Update()
Feb 5, 2005Hi,
I'm using DataAdapter.Update() to update data in a table. My question is; how do I create a trigger that works after the update has completely finished?
For example if my update adds 50 new rows to a table the trigger I've currently got fires after each new row that is added ie 50 times in total. Is it possible to get it to trigger after the last (ie 50th) row is added???
Thanks

Create BAT File And Execute Same In Trigger?
May 9, 2013I am situation, where we have a table named as Project, columns for the table as follows:
Code:
------------------------------------------
ID | ClientCode | ProjectName
------------------------------------------
1 | AAA | Dubai Airport Phase I
2 | AAA | Dubai Airport Phase II
3 | ARC | Salala
4 | MIZ | UMBC Building
------------------------------------------
Now my task was, whenever a project name and other details being created, then a Folder will be created in a server itself in the path E:ProjectFolder in following way:
E:ProjectFolderAAAAAA1
E:ProjectFolderAAAAAA2
E:ProjectFolderARCARC3
E:ProjectFolderMIZMIZ4
You can see here Folder and sub-folder is being created with that following project - client code & ID
I used following trigger to do the same:
Code:
CREATE TRIGGER [dbo].[CreateFolderName]
ON [dbo].[Project]
after INSERT
AS
SET NOCOUNT ON
BEGIN
declare @chkdirectory as nvarchar(4000), @folderName varchar(100), @mainfolderName varchar(100)
declare @folder_exists as int
SET @mainfolderName = (SELECT ClientCode AS Project FROM INSERTED)
SET @folderName = (SELECT (ClientCode + cast(ID as varchar(10))) AS Project FROM INSERTED)
set @chkdirectory = 'E:ProjectFolder' + @mainfolderName + '' + @folderName
[code].....
This worked like a charm, now my next task is using same trigger, I have to create a BAT file inside that SubFolder - T-SQL for creation of BAT File as follows:
Code:
DECLARE @FileName varchar(50),
@bcpCommand varchar(2000)
SET @FileName = REPLACE('E:ProjectFolder[red](select ClientCode from INSERTED)[/red][red](select ClientCode + cast(ID as varchar(10)) from INSERTED)[/red]xcopy_'+ (SELECT cast(ID as varchar(10)) FROM INSERTED) +'.bat','/','-')
SET @bcpCommand = 'bcp "[red]SELECT 'xcopy "E:ProjectFolder' + clientCode + '" "10.0.0.35ProjectFolder" /T /E /I' FROM INSERTED[/red]" queryout "'
SET @bcpCommand = @bcpCommand + @FileName + '" -U SQLServerUsername -P SQLServerPassword -c'
EXEC master..xp_cmdshell @bcpCommand
Here I am not understanding how to insert the above T-SQL in the Trigger as well as the above T-SQL is not right, what's wrong in this?
Last query that will be included in the trigger is to execute the newly created bat file.
