Trigger Execution Permissions
Mar 29, 2004Probably a simple question.
Do triggers execute using the permissions of the user that caused the trigger to execute?
Thanks!

Trigger Execution
Dec 2, 2005If I have two triggers on a table, does one need to finish before the next is executed or will they execute at the same time?

Aug 3, 2006Hi,
I'm not sure if this is the right forum, but I believe it's the closest to my question (if not, please let me know).
I am wondering if it's possible to perform an INSERT to another table in another database from within a trigger. For example:
CREATE TRIGGER inserted_mytable ON mytable
FOR INSERT
AS
DECLARE @rc INT
SELECT @rc = @@ROWCOUNT
IF @rc = 0 RETURN
INSERT INTO [OtherDB].[dbo].mytable2
SELECT *
FROM inserted
Both mytable and mytable2 have the exact same structure. What appears to be happening is that the INSERT statement locks up the mytable database. Is there a permissions problem here, or is this just not possible?
Thanks,

Need Help With Permissions Error On Dbmail Trigger
Sep 26, 2007Good morning,
I'm stumped on this trigger error and I'm hoping someone can help. Here's the background:
BACKGROUND
Running SQLServer2005 on WinServer 2003 RC2. We use a SQL-based business application that has it's own alert system that uses database mail sucessfully, meaning the built-in emailing functions of the application work and can communicate with the database mail profile and send mail without error.
PROBLEM
I'm trying to write a trigger that will automatically send out an email alert after certain actions are performed in the business application. When I enable the trigger and it tries to run it fails with the following error:
SQLDBCode: 229Alerts error: SQLSTATE = 4200Microsoft OLE DB Provider for SQL ServerEXECUTE permission denied on object 'sp_send_dbmail', database 'msdb', schema 'dbo'...
TROUBLESHOOTING
I've seen several articles about DatabaseMailUserRole permissions and have made sure that all users, admin and even guest (for testing) are members of this role. Other than that our setup is pretty vanilla so I'm not sure what else to do.
We only have one large dbase for the app and the fact that the internal emailing fuction works makes me think that the permissions for the msdb are already correct (although I could be wrong)
This problem is driving me crazy so I thank you in advance for any suggestions!

Trigger Procedure Execution On Database Creation.
Feb 2, 2006Hello,
Is there a way to trigger the execution of a procedure when a database is created ? We're using this 3rd party system in which you only specify the database server. Whenever the users create a new "Storage Area", the system actually creates a new database.
I need to handle backups for that system so I want to create a procedure that will generate a backup device and backup jobs automatically whenever a database is created.
I will also need 2 procedures to handle database renaming and deletion. I searched around but can't find a way to trigger the execution of my procedures.

View 3 Replies View RelatedTrigger With Exec Statement Blocking Execution Of Triggering Cmd?
Jul 20, 2005I have a trigger on a table. I am trying to dynamically log thechanged fields on the table to another table, so I am iteratingthrough the bits in COLUMNS_UPDATED() to find what's changed, andgetting the column name programatically. This is all working fine.If I do a regular insert command in my trigger then everything worksfine. However, since I want to retrieve data from the column namewhich I got programatically from the inserted and deleted tables (toget the old and new values) I wanted to do something like this:insert into auditTransactionLog (TableName,PrimaryKeyId,ColumnName,OldValue, NewValue, ActionType) EXEC( 'SELECT(''cmContactInfo''), I.contactID,'''+ @colname+''', D.'+@colname+',I.'+@colname+', '+@action+' FROM inserted I INNER JOIN Deleted D onI.ContactId = D.ContactId')The presence of this line of code appears to be preventing theupdating of the table with the trigger. Is there some reason why Ican't do the EXEC in the trigger? If I did it without EXEC it worksfine but I have no idea of getting at the D. and I. @colname columnsotherwise.Thanks for any help!Rebecca

Transact SQL :: Trigger Execution With OLEDB Connection From In-house Application
Oct 28, 2015issues with triggers in Sql Server 2014.
A few weeks ago I've done a SQL Server migration from SQL Server 2000 to SQL Server 2014.It was a bit tricky but anything worked fine.
I have some legacy VB6 (Visual Basic 6) applications written in house which worked with Databases on the old SQL server 2000.Surprisingly, these applications worked well after the upgrade to SQL Server 2014 without having to change a piece of code.
Now, some users tell me that they receive some unusual message when saving data from these legacy applications.After investing for a few hours, I discovered that triggers are not executed when those users try to save data from grids or forms in their applications.Trying to reproduce the INSERT statement in SQL Server Management Studio, the triggers run well.From the application, they don't.
These applications connect to Database Server thru OLEDB connection with the following ADO connection string :
Provider=SQLOLEDB.1;Password={password};User ID={user};Initial Catalog={db};Data Source={datasource}.the {user} is a true SQL account who have read/write/delete access in the databases.
On the web there is a lot of questions involving the same issue, but only from SSIS.I found some articles about an OLEDB connection parameter named FastLoadOptions with a value of FIRE_TRIGGERS, but nowhere how to put it in the ADO OLEDB connection string.
how to reactivate the "normal" use of triggers from an ADO OLEDB connection ?Either with some obscur parameter in the connection string or options somewhere in the SQL Server 2014.

Static Variables In A SQLCLR Stored Proc Seem To Get Reused From Execution To Execution Of The Sp
Aug 23, 2007after moving off VS debugger and into management studio to exercise our SQLCLR sp, we notice that the 2nd execution gets an error suggesting that our static SqlCommand object is getting reused from the 1st execution (of the sp under mgt studio). If this is expected behavior, we have no problem limiting our statics to only completely reusable objects but would first like to know if this is expected? Is the fact that debugger doesnt show this behavior also expected?
View 4 Replies View RelatedTable Permissions Versus View Permissions
Aug 2, 2006Using SQL Server 2k5 sp1, Is there a way to deny users access to a specific column in a table and deny that same column to all stored procedures and views that use that column? I have a password field in a database in which I do not want anyone to have select permissions on (except one user). I denied access in the table itself, however the views still allow for the user to select that password. I know I can go through and set this on a view by view basis, but I am looking for something a little more global.
View 5 Replies View RelatedExecution Plans &<&> Proportionate Execution Times
Dec 7, 2005Hi I am slowly getting to grips with SQL Server. As a part of this, I have been attempting to work on producing more efficient queries. This post is regarding what appears to be a discrepancy between the SQL Server execution plan and the actual time taken by a query to run. My brief is to produce an attendance system for an education establishment (I presume you know I'm not an A-Level student completing a project :p ). Circa 1.5m rows per annum, testing with ~3m rows currently. College_Year could strictly be inferred from the AttDateTime however it is included as a field because it a part of just about every PK this table is ever likely to be linked to. Indexes are not fully optimised yet. Table:CREATE TABLE [dbo].[AttendanceDets] ([College_Year] [smallint] NOT NULL ,[Group_Code] [char] (12) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Student_ID] [char] (8) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Session_Date] [datetime] NOT NULL ,[Start_Time] [datetime] NOT NULL ,[Att_Code] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ) ON [PRIMARY]GO CREATE CLUSTERED INDEX [IX_AltPK_Clust_AttendanceDets] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [All] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Start_Time], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [IX_AttendanceDets] ON [dbo].[AttendanceDets]([Att_Code]) ON [PRIMARY]GOALL inserts are via an overnight sproc - data comes from a third party system. Group_Code is 12 chars (no more no less), student_ID 8 chars (no more no less). I have created a simple sproc. I am using this as a benchmark against which I am testing my options. I appreciate that this sproc is an inefficient jack of all trades - it has been designed as such so I can compare its performance to more specific sprocs and possibly some dynamic SQL. Sproc:CREATE PROCEDURE [dbo].[CAMsp_Att] @College_Year AS SmallInt,@Student_ID AS VarChar(8) = '________', @Group_Code AS VarChar(12) = '____________', @Start_Date AS DateTime = '1950/01/01', @End_Date as DateTime = '2020/01/01', @Att_Code AS VarChar(1) = '_' AS IF @Start_Date = '1950/01/01'SET @Start_Date = CAST(CAST(@College_Year AS Char(4)) + '/08/31' AS DateTime) IF @End_Date = '2020/01/01'SET @End_Date = CAST(CAST(@College_Year +1 AS Char(4)) + '/07/31' AS DateTime) SELECT College_Year, Group_Code, Student_ID, Session_Date, Start_Time, Att_Code FROM dbo.AttendanceDets WHERE College_Year = @College_YearAND Group_Code LIKE @Group_CodeAND Student_ID LIKE @Student_IDAND Session_Date <= @End_DateAND Session_Date >=@Start_DateAND Att_Code LIKE @Att_CodeGOMy confusion lies with running the below script with Show Execution Plan:--SET SHOWPLAN_TEXT ON--Go DECLARE @Time as DateTime Set @Time = GetDate() select College_Year, group_code, Student_ID, Session_Date, Start_Time, Att_Code from attendanceDetswhere College_Year = 2005 AND group_code LIKE '____________' AND Student_ID LIKE '________'AND Session_Date <= '2005-11-16' AND Session_Date >= '2005-11-16' AND Att_Code LIKE '_' Print 'First query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds' Set @Time = GetDate() EXEC CAMsp_Att @College_Year = 2005, @Start_Date = '2005-11-16', @End_Date = '2005-11-16' Print 'Second query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds'GO --SET SHOWPLAN_TEXT OFF--GOThe execution plan for the first query appears miles more costly than the sproc yet it is effectively the same query with no parameters. However, my understanding is the cached plan substitutes literals for parameters anyway. In any case - the first query cost is listed as 99.52% of the batch, the sproc 0.48% (comparing the IO, cpu costs etc support this). BUT the text output is:(10639 row(s) affected) First query took: 596 milli-Seconds (10639 row(s) affected) Second query took: 2856 milli-SecondsI appreciate that logical and physical performance are not one and the same but can why is there such a huge discrepancy between the two? They are tested on a dedicated test server, and repeated running and switching the order of the queries elicits the same results. Sample data can be provided if requested but I assumed it would not shed much light. BTW - I know that additional indexes can bring the plans and execution time closer together - my question is more about the concept. If you've made it this far - many thanks.If you can enlighten me - infinite thanks.

Execution In Scheduled Job Vs Direct Execution
Nov 29, 2004Here's my case, I have written a stored procedure which will perform the following:
1. Grab data from a table using cursor,
2. Process data,
3. Write the result into another table
If I execute the stored procedure directly (thru VS.NET, or Query Analyser), it will run, but when I tried to execute it via a scheduled job, it fails.
I used the same record, same parameters, and the same statements to call the stored procedure.
Any idea?
Actual Execution Plan Vs Estimated Execution Plan

View 1 Replies View RelatedCLR-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.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where
--specific USER

Jul 23, 2005When a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. 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?
Thanks,
Drop Trigger With A Variable Trigger Name
Sep 20, 2007
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?
thanks in advance

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,
