I want to modify an existing trigger but I get an error.
After modifying this AFTER DELETE trigger when I delete a record from that table I get
The definition of object 'del_nota' has changed since it was compiled.
I've tried all the following
restart SQL Server
EXEC sp_recompile 'dbo.del_nota'
ALTER TABLE note DISABLE/ENABLE TRIGGER del_nota
But I get the same error
On that table I also have 2 triggers for Insert and for Update.
I've disabled them but still the same error.
That trigger initially deletes some records from another table.
I've added after that an insert statement in other table with a select the deleted record from the Deleted table.
What should I do ?
Thank you !

I have a table that is pushed to me from another SQL Server. The table is dropped after it is rotated to a "Current Day" table (Current Data is rotated to prev day before this).
Currently we have jobs that are running to do the "rotating" that are set at a specific time. I had originally created a trigger but clearly a trigger won't work (as I figured out from the comments) since the DDL operation wont continue its flow until after this trigger is complete... It also looks like this is just not possible since I don't have control over the group that is pushing the data to us.
Resolution : I went to the org that pushes the data and requested they add a step that inserts a record into a TableLog table and I am doing my trigger off of that insert instead.
CREATE TRIGGER InsertTest
ON [pace].[Table_Load_Log]
after insert
AS
if exists(select Table_name from inserted where inserted.Table_name = 'POE_Task_Details_SE_TEMP')
BEGIN
--drop table dbo.newtable
exec dbo.sp_start_job N'Make Pace Tables From Temp Table Push’
END
GO
There is no way to do this with a trigger. If you need to know when a CRUD operation on a table is complete, you would need to execute a command after the CRUD operation in the same process that launches it.
I built a trigger in SQL Server to execute a stored procedure when a new row is inserted into the table Balance Data, but the trigger doesn't get fired. I don't know what I am doing wrong or what is happening.
This is the script:
CREATE TRIGGER [dbo].[SP_Trigger]
ON [dbo].[BalanceData]
FOR INSERT
AS
BEGIN
SET NOCOUNT ON;
Exec Schenck.dbo.spCopyData
END
I assume that you are using Transact-SQL.
According to the documentation, FOR INSERT triggers are synonymous with AFTER INSERT triggers by default. This should fire after you have inserted your data into [dbo].[BalanceData].
I would firstly confirm that the data has been inserted successfully (i.e. no check constraint violations, etc) and then confirm what Schenck.dbo.spCopyData is doing. You have turned ROWCOUNT off in the trigger, so perhaps this has given you the illusion that nothing happened.
I'm trying to run a trigger that allows me to insert the inserted data on my local table to the linked server's table. This is what I did:
use [medb]
ALTER TRIGGER [dbo].[trigger1] ON [dbo].[tbl1]
AFTER INSERT
AS
BEGIN
INSERT into openquery(DEV, 'tbl_remotetbl') select * from inserted
END
but it is giving this error:
Cannot process the object "tbl_remotetbl". The OLE DB provider
"MSDASQL" for linked server "DEV" indicates that either the object has
no columns or the current user does not have permissions on that
object.
What seems to be my problem?
Note: I am using SQL Server 2008 R2
Did you try running the command outside the trigger ? Did it work ?
here is the syntax I'm using in my openquery:
INSERT INTO OPENQUERY(LinkedServer_Name,
'select remote_field_1,remote_field_2 from remote_Schema.remote_table')
select local_column1,local_column2
FROM local_Table
Now, with that being said, making this statement work inside a trigger, is something I couldn't do. Above statement woks perfectly when executed by it self. But once it is placed in a trigger, the entire transaction related to that trigger fails. I mean even the insert statement that fires the trigger does not go through, and the main table does not insert the data which was meant to be inserted in it.
i ran into the same issue, and spent many hours trying to figure out how to make an openquery statement work inside update/insert/delete triggers, with no success....
so, here's an alternate solution, maybe this can fix your issue, this is in a scenario where i need to pass data from MSSQL to a MySQL DB.
first, create a holding table, so you can store temporary info that's inserted into a table that will only hold data that i need to pass to MySQL
create table holding_table (ID int, value2 int)
trigger will insert data to the holding table, instead of sending it directly to MySQL
ALTER TRIGGER [dbo].[temp_data_to_mysql]
ON [dbo].[source_table]
FOR insert
AS
BEGIN
INSERT into holding_table (ID,Stock)select a, b from inserted
END
GO
after that, you can just create a task in the SQL server agent, so it can execute your stored procedure every N minutes.
hope it helps, im aware that this is a workaround, but after some investigation and testing, i was unable to make openquery work called within a trigger process..
I need to alter a trigger in SQL Server. After I am doing, do I just execute the trigger similar to how I would do for a Stored Procedure?
ALTER TRIGGER
Yes, that is right, just use ALTER. If you right-click on your trigger in Object Explorer in SSMS and select Script Trigger as/ALTER To, you will see the ALTER statement created for your trigger.
ALTER TRIGGER triggerName
ON tableName
FOR INSERT -- or update & delete
AS
-- sql here

You don't "execute" a trigger. Triggers are "triggered" at certain points depending upon your definition of them.
For example an AFTER UPDATE trigger would run for all rows updated after you send an UPDATE command to the table on which the trigger is created.
I need to delete a trigger in SQL Server. Seems like it should be simple enough, but because there is a thing called a "delete trigger", a trigger that is invoked upon deletion, it seems impossible to find resources on how to actually delete an already existing trigger.
DROP TRIGGER:
Removes one or more triggers from the current database...
You can remove a trigger by dropping it or by dropping the trigger table. When a table is dropped, all associated triggers are also dropped. When a trigger is dropped, information about the trigger is removed from the sysobjects and syscomments system tables.
Use DROP TRIGGER and CREATE TRIGGER to rename a trigger. Use ALTER TRIGGER to change the definition of a trigger...
To drop a trigger, this works:
DROP TRIGGER [trigger_name];
If you want to check weather trigger exist before a drop, then use:
SELECT * FROM [sys].[triggers] WHERE [name] = 'MyTrigger'

I can Drop a Trigger with the Following Query
DROP TRIGGER [Trigger_Name]
(OR)
DROP TRIGGER Trigger_Update
Hope this Must helpfull...
For SQL Server 2016 and above
DROP TRIGGER IF EXISTS [dbo].[trg]

DROP TRIGGER IF EXISTS [dbo].[trigger_name];
