Creating Triggers On System Tables
Mar 1, 2002Hi,
Does anyone know of a way I can create a trigger on a system table (say sysdatabases in master). I know this is not supported but presumably there's a way it can be done by referencing it's equivilant in Information_schema somewhere.
I'm trying to write a script that will automatically set up a backup schedule for a database that has just been created. I was hoping the trigger would query the sysdatabases table for new database name entries, log necessary info in an audit table and then call a backup script to set up the schedule. Any ideas??
Thanks

Triggers Against System Tables SQL 7
Apr 20, 1999I'm thinking of building a trigger against a system table(sysobjects) in
database(a) on server(a) that will assist me in updating a table in
database(b)on server(b). What I need to know from table(b)is if a new table
has been added and removed from database(a) on server(a). I want to use a
store procedure to query the table(b). I was thinking of building a trigger
against my sysobjects table that would update table(b) whenever any tables
are added or removed from database(a). Has anyone built triggers against
system tables? I am running SQL 7.
How To Write Triggers On System Tables?
Apr 15, 2008How can we write triggers on system table dbo.sysobjects,
when i tries to write a trigger, it is giving an error that permission is denied.
I even give a permission of "allow modifications to system catalogs" in Enterprise manager.
still it is not giving permission.
How can i create a trigger on dbo.sysobjects table?
Query System Tables For Triggers
Apr 24, 2008Hello,
I am trying to create a stored procedure that will disable triggers on any given table. Basically I want to pass in a table name as a parameter and query the master table for all triggers that belong to that table...then disable them. I just don't know how to get a list of triggers that belong to a table?
Thanks,

System Event Triggers
Jul 24, 2006Hi, I have several independent, system components that write auditevents to a database locally via ODBC and remotely via TCP, and I havea requirement to audit when the database is available for modification.First, does SQL Server have a concept of starting/stopping specificdatabase instances? Or does my database instance "stop" only when theNT service MSSQLSERVER stops?Second, Oracle has system event triggers, e.g. AFTER STARTUP, but Ican't find an equivalent in SQL Server 2000. What alternatives arethere?Note that I can't rely on the MSSQLSERVER start/stop events in the NTApplication Event log, as the events need to be inserted "in-band" intomy database's event table.TIA,Josh

Creating Triggers Question
Jul 2, 2001Hi,
I'm new to triggers, does anyone know any good resources/articles about creating triggers?
I need to create a trigger for table X, to check BEFORE the update of the table whether a double value for column [X].[Y] exists, if it does (and the value is NOT NULL), do not allow update, if it doesnt allow update/insert statement. This is different from unique keys because as I understand, SQL Server doesnt support multiple NULLs.
Thanks everyone!

Determining What Are System Objects In Sp_help Or System Tables
Jul 20, 2005Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave
View 1 Replies View RelatedMerge Replication Corruption (system Triggers And Views)
Sep 21, 2006All of a sudden none of our merge replications are working. In fact you can't even insert, update or delete and data from the tables in the merge publication. When trying that, we get an error stating:
Msg 550, Level 16, State 1, Procedure MSmerge_ins_E3F43EF8B259476099BBB194A2E1708C, Line 42
The attempted insert or update failed because the target view either specifies WITH CHECK OPTION or spans a view that specifies WITH CHECK OPTION and one or more rows resulting from the operation did not qualify under the CHECK OPTION constraint.
The statement has been terminated.
Currently, the only solution I've found is to delete the publication and recreate it. I'm trying to figure out why this happened. It happened on a development server that to my knowledge, hasn't been changed in a week or so outside of changing the server's IP address. Would that cause such an error to occur?

Creating Multiple Triggers Is Same Sql Script

View 1 Replies View RelatedSynchronize Two Tables Using CLR Triggers
Feb 14, 2008Hi,
I have decided to use CLR Triggers to synchronize data between two different tables but I have a problem. The scenario is this. I do an insert in Table1. Table1 firest the trigger which then inserts a record in Table2. The trigger in Table2 fires a trigger which does an insert to Table1 again.
I need to find a way to disable the trigger so that it will not go in an infinite loop when I insert a record in either of the tables. What I have done so far is to disable Table2's trigger before I commit my insert to Table2 so that Table2's trigger won't fie. I will then enable the trigger after the insert is committed. Also, I have a webservice which manages the inserts/updates/deletes. I call webmethods from this webservice in my clr triggers.
Help please!
Thanks,

Approach To Creating A Procedure That Contains Dll , Dml To Upgrade A System
May 15, 2007Hi.I am between beginner and intermediate level of knowledge of sql server.I am dealing with an sql server 2005 situation (oracle also but thats anotherthread/story).I need to assemble a process that an end user can use easily to update adatabase. The update consists of some column lengthening, checks to make surenew data will fit in columns after the ddl is executed, and then generatingnew data (changing primary key column data and keeping all the referingobjects/rows in sync). I also don't want to have an error leave things in abad state.I'm wondering if there is anything special to look out for, and if there areany suggestions on approach. Here is my current approach:write a single stored procedure to do all the work.have it check for existence of table01_bak and table02_bakdelete them if they existrecreate themcopy table01 and table02 to table01_bak and table02_bakcalculate the new primary key values neededmake sure they will fit (I need to bail out and tell the user to make anadjustment at this point if they will not)start a transactiongenerate the new primarky key values and insert themupdate all the other tables that refer to the still existing primary keys topoint them to the newly generated onesdelete all the old rows using the original primary keyscommit a transactiondelete the table01_bak and table02_bakthanksJeffJeff Kish

Triggers-Inserted/Deleted Tables
Mar 22, 2000I am reading the WROX "Professional SQL Server 7 Programming" book.
The following code appears on page 424:
CREATE TRIGGER ProductIsRationed
ON Products
FOR UPDATE
AS
IF EXISTS
(
SELECT 'True'
FROM Inserted i
JOIN Deleted d
ON i.ProductID = d.ProductID
WHERE (d.UnitsInStock - i.UnitsInStock) > d.UnitsInStock / 2
AND d.UnitsInStock - i.UnitsInStock > 0
)
BEGIN
RAISERROR('Cannot reduce stock by more than 50%% at once.',16,1)
ROLLBACK TRAN
END
The trigger fires when an UPDATE is made to Products table. The author states that the Inserted and Deleted tables only exist for the life of the trigger, not before, and not after the trigger runs. If this is true, then why would there be any rows in the Deleted table in this case? No rows were
deleted within the trigger. As far as I can see, no rows have been updated
either. If the condition does exist, no rows will be updated, and an error will be displayed. Otherwise, the row will be updated. Then there would be a row in the inserted table. But then the trigger is finished and the inserted table for that trigger disappears. I think my logic is flawed, which is why I am writing. I don't think I fully understand the Inserted and Deleted tables.
Any help would be greatly appreciated.

Triggers Affecting Multiple Tables
May 4, 2004I have a table "PageInfo" wich has columns "PageID, Title(has "AboutUs" as one of the values), DateModified, Active". My other table is "AboutUs" and has columns "ID, WhatsNew, Welcome, Active".
My goal here is that if table "AboutUs" is affected as an "INSERT" or an "UPDATE" on any row, I want "PageInfo.DateModified" WHERE "PageInfo.Title = AboutUs" to be updated with "getDate()". Don't know if I'm clear enough but thanks in advance.

Using Triggers To Add Foreign Keys To Child Tables
Apr 29, 2004I have a situation that I must resolve. I have a program being used by many but I had to create a new table to provide a new feature. The problem I have is this table must use the primary key from the parent table as its primary key, meaning when a user adds a new record to parent table, I need to instantly add the primary key to the child table. Now this was done in the program using sql statements, but I need to implement a trigger or such as to keep me from having to reinstall application on many computers.
basically person inserts new record, then I need to get the new primary ket and add insert it into the child tables. how can I do this with a trigger. I have tried to use an insert into statment with my trigger, but I can't seem to pass the parameters correctly.
CREATE Trigger dbo.Table_Borrower_Insert_Keys

Triggers - How Do You Join INSERTED Vs DELETED Tables?
Sep 11, 2001I want to compare the before and after values of an UPDATEd column using a trigger. I want to know if the value in the column has changed. Simple? No!
As you know, SqlServer puts the before image of the UPDATEd rows into the DELETED virtual table and the after image of the UPDATEd rows in the INSERTED virtual table.
So you would get the before and after data by doing a SELECT on these tables.
But here is the problem - how do you join the tables? What if there are >1 rows in these 2 tables (because the UPDATE affected >1 rows) - how do i know which "old"/DELETED rows correspond to which "new"/INSERTED?"
Ok - I could join the 2 tables on the primary key, but what if the primary key was updated? In that case the join would not work - the DELETED table would contain the old primary key value and the INSERTED table would contain the new (different) primary key value. In fact, ALL of the columns may have been changed by the UPDATE.
Now, there is another thing to try with triggers - the
IF UPDATE ( <columname> )
test. This is designed to tell you if a specified column was UPDATEd by the last UPDATE. However, this will return TRUE for any UPDATE that mentions the column - even if the UPDATE does not change any data! So I cannot determine whether a certain column has had its value changed with this either.
So then you can try another test mentioned in the docs for CREATE TRIGGER - the
IF COLUMNS_UPDATED()
test. However, this will report that a column has been updated, NOT whether the data has changed as aresult of that UPDATE.
So if you UPDATE the value in the column to the same value as it was beforehand (admittedly, a pointless thing to do, but it could happen in some apps), this fuction will say, yes, this column was updated.
So my question remains - how do I know if the data has changed in a column after an UPDATE, using a trigger?
Any ideas?
Auto Create History Tables And Triggers
May 30, 2007For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.
We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.
The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:
1) Queries system tables to retrieve table schema for @TableName parameter
2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.
3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

Triggers On Tables Underlying A Partitioned View
Jul 23, 2005We have a partitioned view with 4 underlying tables. The view and eachof the underlying tables are in seperate databases on the same server.Inserts and deletes on the view work fine. We then add insert anddelete triggers to each of the underlying tables. The triggers modifya different set of tables in the same database as the view (differentthan the underlying table). The problem is those triggers aren't firedwhen inserting or deleteing via the view. Inserting or deleteing theunderlying table directly causes the the triggers to fire, but not whenthe tables are accessed as a result of using the view.Am I missing something? The triggers are 'for insert' and 'fordelete'. No 'instead of' or 'after' triggers.
