Getdate() In Insert Trigger
Jun 10, 2008
Hi all,
I am trying to create a trigger for a table, when a record is inserted into the table, the currdate_time field should be inserted with the current date and time. I tried below in Oracle
create trigger test_trg
before insert on test
for each row
begin
:new.curr_datetime := sysdate;
end;
/
For Sql server, I tried the below,
create table test (num smallint, curr_datetime datetime)
go
create trigger test_trg
on test
for insert
as
insert into test (curr_datetime) select getdate() from dual
I inserted a record into test:
insert into test (num) values (8)
select * from test
num curr_datetime
8 NULL
NULL 2008-06-10 09:49:06:317
Trigger is inserting NULL values. Please give me your suggestions.Thanks.

I have a trigger on a table that basically logs changes to another table. Something like this:
Code Snippet
...AFTER INSERT
insert into LogTable
select RowID, GetUTCDate()
from INSERTED
Here's the question: Using GetDate() or GetUTCDate(), if the INSERT query within the trigger takes 20 seconds, will all records inserted into LogTable be inserted with an identical date value, or will the last records inserted have a date value 20 seconds greater than the first records?
In essence, What is the scope or duration of using GetDate() ?

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

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

Hi,
We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.
If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.
We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.
We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:
/* Different functions to get current timestamp €“ all have been tested to produce the same results */
/*
SELECT GETDATE()
GO
SELECT CURRENT_TIMESTAMP
GO
SELECT {fn Now()}
GO
*/
/* Use these statements to delete the tables to allow recreate of the tables */
/*
DROP TABLE COMMIT_TEST
DROP TABLE COMMIT_TEST_UPDATE
*/
/* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */
CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */
GO
CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */
GO
/* Use these statements to delete the triggers to allow reinsert */
/*
drop trigger LOG_COMMIT_TEST_INSERT
drop trigger LOG_COMMIT_TEST_UPDATE
drop trigger LOG_COMMIT_TEST_DELETE
*/
/* Create insert, update and delete triggers */
create trigger LOG_COMMIT_TEST_INSERT on COMMIT_TEST for INSERT as
begin
declare @time datetime
select @time = getdate()
insert into COMMIT_TEST_UPDATE (PKEY,LAST_UPDATE)
select PKEY, getdate()
from inserted
end
GO
create trigger LOG_COMMIT_TEST_UPDATE on COMMIT_TEST for UPDATE as
begin
declare @time datetime
select @time = getdate()
update COMMIT_TEST_UPDATE
set LAST_UPDATE = getdate()
from COMMIT_TEST_UPDATE, deleted, inserted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
GO
/* In our application deletes should never occur so we don€™t log when they get modified we just delete them from the UPDATE table */
create trigger LOG_COMMIT_TEST_DELETE on COMMIT_TEST for DELETE as
begin
if ( select count(*) from deleted ) > 0
begin
delete COMMIT_TEST_UPDATE
from COMMIT_TEST_UPDATE, deleted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
end
GO
/* Delete any previous inserted record to avoid errors when inserting */
DELETE COMMIT_TEST WHERE PKEY = 1
GO
/* What is the current date/time */
SELECT GETDATE()
GO
BEGIN TRANSACTION
GO
/* Insert a record into the primary table */
INSERT COMMIT_TEST (PKEY) VALUES (1)
GO
/* Simulate additional processing within this transaction */
WAITFOR DELAY '00:00:10'
GO
/* We expect at this point that the date is written to the database (or at least we need some way for this to happen) */
COMMIT TRANSACTION
GO
/* get the current date to show us what date/time should have been committed to the database */
SELECT GETDATE()
GO
/* Select results from the table €“ we see that the timestamp is 10 seconds older than the commit, in other words it was evaluated at */
/* the insert statement, even though the row could not be read with a SELECT as it was uncommitted */
SELECT * FROM COMMIT_TEST
GO
SELECT * FROM COMMIT_TEST_UPDATE
Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).
Regards,
Mark

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
