How To Write This Trigger
Nov 1, 2006I have table T1 with the fields: ID,Type,Status,F1,F2,F3,F4 in database1. I also have T2 in Database2 which has the same fields and some extra fields. Now based on the T1.Type=Insert or Update, I need to perform either update or Insert in T2 based on where T1.ID=T2.ID and T1.Status<>’Done’. If this is a success, I need to set T1.Status=’Done’ for the updated records. So this should only be updated records. T1 is a frequently inserted table, so there might be more than one record coming there at the same time. How should I write my insert trigger and correctly set T1.Status=’Done’, any example would be greatly appreciated.

I am pretty new to MSSQL server environment. In Oracle i write Trigger and compile it at command prompt in case of SQL plus the same way i need to know where we write the script for SQL server. Is there any menu driven editor where we can write or simply writing a trigger in SQL Query analyzer and executing it will work
Please advice.

T-SQL (SS2K8) :: Trigger To Call A Program To Write Text File Onto A Folder In Server
Apr 29, 2014I have created a trigger to call a program that is written by our program. The program is basically read the record in the table and write to a text file, then delete the record from the table.
The trigger is a after insert trigger. After we added the trigger, we insert a record to the table. The result is that the record still and did not get deleted. Also, the text file didn't get created either. It seems that it take a long time for the record to be written to the table.
But if we just run the program (a exe file), it can write a text file in the folder and delete the record. the trigger is basically:
USE [Zinter]
GO
/****** Object: Trigger [dbo].[ZinterProcess] Script Date: 04/29/2014 18:34:56 ******/
SET ANSI_NULLS ON

Backup Master Key, Cannot Write Into File 'c: Empmaster'. Verify That You Have Write Permissions, That The File Path Is Valid.

I tried to backup the master key by the following syntax :
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'
BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'
but it failed and i got the following message:
Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.
NB: I am using the "sa" user to execute this command.
I know that we have a security permission issue , but where and how ?

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.

Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.

View 4 Replies View RelatedUpdate Trigger Behaviour W/o A Trigger.
May 30, 2008Hi,
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.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on 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
