Insert Trigger Using Variables Help
Dec 19, 2006
Can somebody please help me with compiling my insert trigger below. I am fairly new to SQL server 2000 and I am having troubles with using variables in insert triggers. The trigger that I am creating will basically update another table based on a certain criteria that is not specified below. I am hoping to first get my trigger to work then apply the criteria on when to fire afterwards. I just need help with being able to store values in my declared variables for insert into another table. Thanks in advance for everyones help.
Use database_testing
IF EXISTS (SELECT name FROM sysobjects
WHERE type = 'TR' AND name = 'Trigger_Name')
DROP TRIGGER Trigger_Name
GO
CREATE TRIGGER Trigger_Name
ON [trigger_table] FOR INSERT
AS
Declare @resource_id int = inserted.resource
@type = varchar(100) = inserted.type
@date_logged (datetime) = inserted.creation_date
@created varchar(100) = inserted.username
Insert into table_A (resource_id, resource_type, date_created, created_by)
values (resource_id,type, date_logged, created)

Fairly new to triggers and stored procedures and so far I haven't had to pass any variables or even call an SP from a trigger. The problem I have is to pass a 'callid' variable from an insert trigger to a stored procedure.
The SP is to delete any rows that already exist that contain the passed 'callid' and then insert the new inserted data (using variables again hopefully).
Is this at all possible and if so what is the syntax for passing the variable from the trigger and then reading it into the stored procedure ?
TIA

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.

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

When I provide multiple insert SQL then only first insert works while rest insert statements does not work

I'd like to "pass" the BULK INSERT statement a variable for the table_name and file_name arguments. I've tried the following:
-----
BULK INSERT @strTableName
FROM @strDataFileName
WITH
(
FIELDTERMINATOR = "",
ROWTERMINATOR = ""
)
-----
where the @strTableName and @strDataFileName variables are passed in via stored procedure arguments. I get the error:
Incorrect syntax near '@str_TableName'.
Is there a way to do this?
Thanks!

I am new to scripting in general and I've run into an issue when attempting to write a VB variable to a database table in SQL Express. I am trying to record the value of the variable to the db, but it does not appear that the value is being passed to SQL. If I hard code the values in the SQL statement it works fine. Can someone explain what I'm doing wrong accomplish this? My code is below. Thanks in advance.
file.aspx
<asp:SqlDataSource ID="SqlDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:SqlConnectionString %>"
SelectCommand="SELECT * FROM [Table]"
InsertCommand="INSERT INTO [Table] (field1, field2) VALUES (& variable1 &, & variable2 &);" >
</asp:SqlDataSource>
file.aspx.vb
Protected Sub Button_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button.Click
Dim variable1 As String = FileUpload.FileName
Dim variable2 As String = Date.Now
Dim path As String = Server.MapPath("~/directory/)
If FileUpload.HasFile = True Then
Try
SqlDataSource.Insert()
FileUpload.PostedFile.SaveAs(path & _
FileUpload.FileName)
End Try
End If
End Sub

I was wondered what the most efficient way to do the following in MS SQL (2000, 2005, and above):
Psudo Code:
DECLARE @var1, @var2, @var3 VARCHAR(100)
SET @var1, @var2, @var3 = (SELECT var1, var2, var3 FROM Table WHERE [ID] = @someID) <-- Returns only one row
Right now I'm making a call for every variable. I should play around with temp tables but seems like allot of overhead code just to get 3 values. I'm thinking there's a simple way to do this.
Thanks for any ideas

Hey Guys:
--- Not sure if this should be moved to webforms forum, or if it belongs here ---
Alright, I have been dealing with this issue for a few days now, and have found a few solutions but they all seem to throw different errors so I figured I'd ask here.
What i am trying to do is have a webform where user enter data, and have the data passed across forms, then displayed and inserted into a database on another form. THe first for has an asp:rangevalidator control dymamicly built so I cannot simply take of the tags and use the old style.
Eventually the user will be directed to a paypal form, and upon successful completion be redirected to the page with the insert command within it, but for now, passing it to a second page for review, then inserting it will work.
I am not sure how to accomplish this, a tutorial or a code example would be great!! I have though about panels, creating public objects, etc, but all the solutions I have found have one issue or another when I attempt to create them.
I'm using asp.net 1.1, VB.net and SQL server.
Thanks,
Brian Sierakowski

I am trying to insert different number of columns into variables. This is what it does If I use a static columns.
declare @AccountType nvarchar(10)
declare @Total numerical(15,2)
declare @1 numerical (15,2)
declare @2 numerical (15,2)
declare @3 numerical (15,2)
#MonthtoDate  temp table is created using a dynamic pivot query.Â
Data looks like this :
Account Type  1 2
3 Total
Type 1 3
0 4 7
Type 2 5
7 1 13
Select @AccountType = AcctType , @Total = MonthToDate, @1 = [1], @2 = [2], @3 = [3] Â from #MonthtoDateÂ
However the issue is with [1],[2],[3] columns. Those are the number of days of the month. If today is the 3rd day of the month, we only need to show 3 days. So the final table has column [1],[2],[3] and @AccountType and @Total .
We want to run this query everyday to get the moth to date values.If we run this tomorrow, it will have 4 date columns [1], [2],[3],[4]Â and @AccountType and @Total .

I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.
My problem appears to be that I am unable to fill the variables with values, and I cannot understand why it isn’t working, my code is:
ALTER trigger [dbo].[antall_liter] on [dbo].[ProdTr]
for insert
as
begin
declare @liter as decimal(28,6)
[Code] ....

Hi.
Replication is not an option for me so I am trying to creat a trigger that will basically copy any new record to another database. I am using an on insert trigger and I get all records from the table inserted to the new db not just the new record.
Any ideas?
Thanks.

I am trying to write an insert trigger for the following problem. I have a table that contains a field (amount) that contains currency amount. Each row could be a record from a transaction in a different country. I would like each record to be converted into U.S. currency as it is inserted. So I created an other table that contains that exchange rate. How can I create a trigger that does this?
Tax Detail Table Exchange Table
Account# int Country char
Description char ExchangeRate Money
Amount money

I am working with MSS 6.5. Any and all help will be greatly appreciated.

Really simple question - I have the following trigger for the INSERT event for Tbl_B:
CREATE TRIGGER calc_total ON [dbo].[Tbl_B]
FOR INSERT
AS
DECLARE @VATRate AS decimal(19,2)
SET @VATRate = (
SELECT Val
FROM Tbl_Numeric_Refs
WHERE Ref = 'VATRate'
)
UPDATE Tbl_B
SET [Total] = ((@VATRate / 100) * [PriceA]) + [PriceA],
[VATRate] = @VATRateHow can I restrict the UPDATE within the trigger to the record(s) being INSERTed? Or am I over-complicating things, and should use a simple UDF for this instead?

Is it possible to pick up the value that is being inserted within the scope of a trigger? For example, if I were to run the following
INSERT INTO people (firstname, lastname)
VALUES ('George', 'V')
Would it be possible to access these values in a trigger before they are inserted?
CREATE TRIGGER trigger1
ON people
FOR INSERT
AS
IF EXISTS (SELECT 1 FROM table1 WHERE firstname = <the value being inserted>) BEGIN
Print '1'
END
ELSE BEGIN
Print '2'
END

Rightio - this is probably a simple question for you SQL afficionados.I have written a trigger to update a master table with a CreateDate field. Simple enough I thought but it updates this field when the existing record is edited as well - not so good.This is how it looks like:CREATE TRIGGER CreateDateON MasterFOR UPDATE ASDECLARE@idMaster intSELECT @idMaster = idMaster from Insertedupdate Masterset CreatedDate = getdate()where idMaster = @idMasterGOWell I know I can write an IF statement that will basically say if the field is not null then only update - fair enough - but is there a simpler way to do this? Is there a way I need to write my CREATE TRIGGER statement that ONLY makes it run when it is a NEW INSERT ONLY?THANKS!

So... dear friends
I want to insert values to a table without firing the foreign key Constraint.
I think one way is to insert values into the parent table first and then perform the initial insert.
Is this possible with an INSTEAD OF INSERT Trigger or another way? If yes can you make an example? I want to check for dublicate values in the parent table too!!
Thanx!

Hi there,
After some head scratching and much research and trying I am unable to figure out how to do the following Insert Trigger. Maybe it shows a flaw in my database design?
I have a user front end where a user can assign a certain job to be done and assign it to one and only one shift and one or more equipments to do this job on.
When user clicks on Assign button it will insert rows into Jobs table via an insert stored procedure. Jobs table has following fields : ShiftID, and a JobEquipmentID since Job can be done on one or more equipment. This field, JobEquipmentID, will refer to a child table JobEquipment. What is the best approach to update this secondary table? I need to update JobEquipmentID but I do not have it until I update JobEquipment table? CRAZY!!! HELP
