how can i Create a trigger to check if a value is NULL or = 0
i am trying :
CREATE TRIGGER [TR_User]
ON [User]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM User WHERE (Category = 0 OR Category IS NULL)

I have just one table but need to create a trigger that takes place after an update on the Orders table. I need it to multiply two columns and populate the 3rd column (total cost) with the result as so:
Orders
---------
ProductPrice ProductQuantity TotalCost
-------------- ------------------ -----------
£2.50 2
£1.75 3
£12.99 2
Can anyone please help me?
I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country
FROMinserted
OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country
END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------
I use a cursor to handle multiple rows in an update query.

Is there an easier och better way to do this?
I´m a bit unsure of this code.
Thanx!

I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.
A
ID

Joe

Fred

Ian

Bill
B
ID

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

This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them
1) Create the table
2) Create the trigger
3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value
4) Drop the trigger
5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
Any thoughts would be much appreciated

Hi
I am trying to use multiple insert for a table T1 to add multiple rows.
Ti has trigger for insert to add or update multiple rows in Table T2.
When I provide multiple insert SQL then only first insert works while rest insert statements does not work
Anybody have any idea about why only one insert works for T1
Thanks
In case of a bulk insert, the “FOR INSERT� trigger fires for each recod or only once?
Thanks,
I 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.

i do have my 'Product' TABLE IN DATABASE 'ABC'

6004 0 cables NULL ENVD 14
6005 0 processor NULL ENVD 14
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.

Guid(PK)Not Null,
AcademyId(FK), Not Null,
Name,Null
WorkPhone,Null
CellPhone,Null
Email Id,Null
Other.Null
Since we have given Null to ''Workphone'',''Cellphone '', ''Email ID''.when inserting the data into these table.if the particular columns are empty while inserting also the data will get populate into the table.And.I need is if these columns are ''Workphone'',''Cellphone'' , ''Email ID'' they cant insert the data into table.
Like it must trigger like ''Please enter atleast one of these ''Workphone'',''Cellphone'' , ''Email ID'' columns.

View 4 Replies View RelatedHi 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.
Appreciate any help.

Hi 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.
Thanks in advance

View 9 Replies View RelatedHi,
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 "Örder" table has been changed (when it becomes status = 7) then I need to insert records in "Shipment" table.
Order Table:
OID===Order_Product===Order_Description===Order_Status
Shipment Table:
SID===Shipment_Description===DateTime===Status
I tried to create a trigger, but it is not working properly;
Create Trigger trg_InsertShipment ON [dbo].[Order]
FOR Update
AS
INSERT INTO Shipment
(
SID,
Shipment_Description,
DateTime,
Status
)
Select
'001' as SID,
'Nothing' as Shipment_Description,
'01/01/2007' as DateTime,
'Ready' as Status
WHERE Order.Status = 7
===============================================================
But it inserts the records into Shipment Table every time the status field or any other field in the Order Table is changed. What I want is that, "When Status Column in Order Table is Updated to 7, then insert record in Shipment Table".
How can I do that???
Thanks in advance...

just started to write my first trigger for a view. Of course I got some errors, which I could could resolve except one.

Hi,
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!!!!!!!!!!!!!!!!
Hi -
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.

Hi,
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
