hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Â
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Hi,
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,

I want to create a trigger in SQL 2000 Enterprise, but not sure about triggers, how they work, etc. I just know that I was told I could create a trigger when new info is added to one table and check another table to see if this info is already in the other table, if not, copy the data to the other table too.
Would this be what a trigger can do for me?
what would be the best place to learn how triggers work, how to write one and install it, test it, etc?

I have 3 tables on my db, Projects, ProljectAllocationLog and Users
Project consists of Projectid(PK), ProjectName, UserID
ProjectAllocationLog consists of ProjectAllocationID(PK), Projectid, UserID,Date
Users consists of UserID (PK), Fullname
Over the course of time the user allocated to a project may change. The db has been set up to always show the most current user in the UserID of the Projects table,
I want to create a log that will record everytime that user has changed. (ProjectAllocationLog)
Having read through some examples posted on Forums, I believe that I can do this with a trigger, but I am not sure if I am doing it right, the trigger I have written is
Create Trigger tr_UpdateAllocationLog
ON Projects
AFTER Update
AS
If NOT UPDATE (Userid)
DECLARE @PROJECTID
DECLARE @NEWUSER
DECLARE @PREVIOUSUSER
SET @PROJECTID= (SELECT projected FROM Inserted)
SET @NEWUSER = (SELECT UserID from Inserted)
SET @ PREVIOUSUSER = (SELECT UserID from Deleted)
If @NEWUSER <> @PREVIOUSUSER
INSERT INTO ProjectAllocationLog (ProjectID, UserID, Date) VALUES (@PROJECTID, @NEWUSER, GETDATE())
Go
I would appreciate any comments

i am trying to create a trigger which when I insert a "y" on a student table in insCheck column, instructor table will create a record of the same person.
The reason is there are two tables are in my DB, student and instructor table. Student can be a instructor so whenever insCheck conlum in studnent table is checked as "y", instructor table should be populated.
Both table studentId and instructorId inserted as manually so that I am not sure how i should populate the instructor's table just fName, mI, and lName and I have go back to the instructor table and populate the rest of the table manually or is there any way to poppulate the insturctorid also while trigger is populate the name onthe instructor table.
My Two tables DDL are like down below
create table student(
studentId char(4) not null primary key,
fName varchar(25) not null,
mI char(1) null,
lName varchar(25) not null,
insCheck char(1) not null,
);
create table instructor(
instructorId char(4) not null primary key,
fName varchar(25) not null,
mI char(1) null,
lName varchar(25) not null,
instructorQual varchar(100) not null,
);

There are 2 tables: OrderID and Order_Details
CREATE TABLE Orders
(OrderID int
Constraint Order_ID_pk primary key
, CustomerID nchar (5)
, EmployeeID int
, OrderDate datetime
, RequiredDate datetime
, ShippedDate datetime
, ShipVia int
, Freight money
, ShipName nvarchar (40)
, ShipAddress nvarchar (60)
, ShipCity nvarchar (15)
, ShipRegion nvarchar (15)
, ShipPostalCode nvarchar (10)
, ShipCountry nvarchar (15)
)
CREATE TABLE Order_Details
(OrderID int NOT NULL
, ProductID int NOT NULL
, UnitPrice money NOT NULL
, Quantity smallint NOT NULL
, Discount real NOT NULL
, constraint Order_Details_PK
Primary key (OrderID, ProductID)
)
Create a Transact SQL procedure, customer_activity, that would, for a given CustomerID, return the number of orders that customer has made, average amount of all the customer orders, and the maximum customer’s order. The CustomerID should be the stored procedure’s input parameter. The stored procedure should use the view customer_orders.
what kind of code to create this? it says i need to use a view customer_orders, which i made:
create view customer_orders as
select orders.orderID, customerID, sum(order_details.orderID) as orderamount
from orders, order_details where orders.orderID=order_details.orderID
group by orders.orderID, customerID
but i don't know how to do it.
Next: the trigger:
Write a trigger that would, for any order entered (inserted), print the order amount as well as the customer’s average and maximum order so far, by using the view and the stored procedures created in this lab.
please and thank you

I am creating a trigger in SQL Server that will activate when my Athelete table has something "Inserted"
So far it works except for the fact that it won't insert a null into the Equipment_ID field. I need it to autoincrement, or do the last number + 1...
CREATE TRIGGER TRG_NEW_EQUIPMENT1
ON ATHLETE AFTER INSERT
AS
BEGIN
INSERT INTO Equipment Equipment_ID, Equipment_Model, Equipment_Year, Equipment_Brand, Equipment_Color, Equipment_Condition_Rating)
VALUES ('Big Spin','2016','K2','Blue','5')

I've got a ContactInfo table, that stores a variety of information about a contact (i.e. first/last name, address, phone, date of birth, status, etc.). I seem to be randomly loosing contacts though. Older backup's of my database still show a given contact, but the current one doesn't. It's happened a few times, and I can't seem to track what's causing it. (Nothing that I'm doing *should* be causing the contact to be deleted).
I'm looking to create a delete trigger for the table, so that any time a record gets delete, it will record what record got deleted (contactID, firstName, lastName), as well as what time it got deleted, and if possible, what function cause the delete (what function was accessing the table when the delete happened).
I've got some basic knowledge of SQL, and SQL statements, but my knowledge is limited... so any help on this would be greatly appreciated - or, if someone could point me to a website with good suggestions and examples, to help me create a trigger to monitor this stuff. I would be greatly indebted for any help that could be offered.
Here is kind of a shell for a delete trigger that I have been able to put together from some various examples I've found.
IF EXISTS (SELECT name FROM sysobjects
WHERE name = 'trDeleteContactInfo' AND type = 'TR')
DROP TRIGGER trDeleteContactInfo
GO
CREATE OR REPLACE TRIGGER trDeleteContactInfo
on ContactInfo
FOR DELETE
AS
EXEC master..xp_sendmail 'my@email.com',
'Contact has just been deleted from ContactInformation Table'
GO

Can anyone help me with setting up a simple Delete Trigger, so that whenever a contact gets deleted from the table, it will log as munch information as possible about what just happened (maybe what functions just got ran, what info just changed, whatever...); so that way I can try and get some more information on the problem, and try and diagnose what is causing the deletions.

Can anyone assist me?
I am trying to create a trigger within our local database that will allow me submit an email to a local exchange server. Its an internal email that our company has created for responses by candidates when the original stored procedure meets a condition of TRUE.
Is SQL 7.0 capable of sending emails to a specified address through a Trigger? I was told it could but have yet to come across any documentation backing this up.
Would anyone know the generic syntax I can use to create such a trigger?
Any suggestions would be appreciated.
Thanks in advance,

Hello,
I have a problem that definitely has me stumped.
I have a view that looks at data in a different database. Some of the fields in the view are updateable and some are not. I am trying to create a trigger against the view that will allow me to audit the updates into an audit table. I am having problems when trying to execute the CREATE TRIGGER statement.
I keep getting the message...
Server: Msg 208, Level 16, State 4, Procedure updDocInfo, Line 1
Invalid object name 'vwDC_DocInfo'.
Where vwDC_DocInfo is the name of the view.
Does anyone have any idea why I might be getting this error? The VIEW definitely does exist and I am executing the script in the same database as the view.
The script is included below...
CREATE TRIGGER updDocInfo
ON [vwDC_DocInfo]
FOR UPDATE AS
DECLARE @ModifiedDate AS DATETIME
SELECT @ModifiedDate = GETDATE()
-- Audit OLD record.
INSERT tblAudit_DC_DocInfo

I am trying to update a fields with an UPDATE statement but I keep getting the error message when I run the query.
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have this Update trigger that I know is causing the error message because I guess it's not built to manage multi-row updates.
Can someone help me re-write it. I also tried using the WHERE p.ID = p.ID but when I do that it modifies all rows in the modifieddate column instead of just the cells/rows that I'm updating
ALTER TRIGGER [dbo].[MultitrigCA]
ON [dbo].[ProdDesc]
AFTER UPDATE
AS
SET NOCOUNT ON
IF UPDATE (codeabbreviation)
UPDATE p
sET p.ModifiedDate = GETDATE()
FROM ProdDesc AS p

hi!
i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.
i want to avoid the trigger launching for the last column (UpdatedOn).
how can i detect the rows that changed, and modify only the update date/time?
i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.
another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)
thank you in advance.

I am using the tables created by the aspnet_regsql.exe tool for security. Basically, I need to ensure that an account named Administrator is never deleted. I also have a role named administrator, and I need to make sure that Administrator is never removed from the administrator role.Can I create a trigger to ensure that the Administrator is never deleted and that the Administrator is never removed from the Administrator role? I know it will probably be two separate triggers: one on the aspnet_users table and one on the aspnet_usersinroles table.Thanks a lot for the help!
