How To Create DML Trigger
Jan 6, 2015
We have Tables like parent and Child Table.Like we have Child Table as Name AcademyContacts,In that we have Columns like
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.

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.
CREATE TRIGGER NotifyDateFieldUpdates
ON RelocateeRemovalist
For INSERT, UPDATE, DELETE
AS
DECLARE @RemovalistNumber VARCHAR(200)
DECLARE @RelocateID INT
/*InspectionDate */
DECLARE getInsp CURSOR FOR SELECT RelocateID,RemovalistNumber
FROM INSERTED a LEFT JOIN DELETED b ON (a.RemovalistNumber=b.RemovalistNumber and a.RelocateID=b.RelocateID)
WHERE a.InspectionDate IS NOT NULL AND b.InspectionDate IS NULL
OPEN getInsp
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber
WHILE (@@FETCH_STATUS <> -1)
BEGIN
INSERT INTO RelocateeRemovalistFieldEntry(RElocateID, RemovalistID)SELECT
RelocateID,RemovalistID FROM INSERTED a LEFT JOIN RelocateeRemovalistFieldEntry b ON
(a.RelocateID=b.RelocateID AND a.RemovalistNumber=b.RemovalistNumber)WHERE b.RElocateID is null
UPDATE RelocateeRemovalistFieldEntry SET InspectionDateDateTime=GETDATE()
WHERE RelocateID=@RelocateID aND RemovalistNumber=@RemovalistNumber
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber
END
DEALLOCATE getInsp
GO
This is what I was able to come up with so far,but when i check the syntax it gives me an error "Ambiguous column name "RelocateID" and "Ambiguous column name "RemovalistNumber" I don't know what is it trying to tell me here and couldn't find much help.
Regards and thanks

i do have my 'Product' TABLE IN DATABASE 'ABC'
Product TABLE OUTPUT
PRODUCT_CODE PRODUCT_TYPE PRODUCT_DESCPRODUCT_ID PRODUCT_GROUP_CODE
6001 computer NULL ENVD14
6002 keyboard NULL ENVD14
6003 mouse NULL ENVD14
6004 cables NULL ENVD14
6005 processor NULL ENVD14
AND 'Product_Mst' TABLE IN DATABASE 'XYZ'
Product_Mst OUTPUT
PROD_CODE Prod_Ver PROD_TYPE PROD_DESC PROD_ID PROD_GRP_CODE
6001 0 computer NULL ENVD 14
6002 0 keyboard NULL ENVD 14
6003 0 mouse NULL ENVD 14
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
6002 0 keyboard 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.

Hi 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.

What I was trying to use to create the trigger was the same code I would use on Sql Server Express:
cmd.CommandText = "CREATE Trigger [contactsLastUpdate] on [contacts] for Insert, Update " +
"AS " +
"Begin " +
"SET NOCOUNT ON " +
"Update t " +
"set syncLastUpdate = GetDate() " +
"From contacts t " +
"Join inserted i " +
"On t.id = i.id " +
"SET NOCOUNT OFF " +
"End"; +
But I get an error message:
"There was an error parsing the query. [ Token line number = 1,Token line offset = 8,Token in error = Trigger ]"
How do you guys create Triggers on SQL Server CE (2005)?
Thanks

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

I created and successfully tested a trigger on a test database. Now that Iwant to put this on a production system, the create trigger statement takesway too long to complete. I cancelled after a few minutes. The testtrigger took just a second to create. The test and production databases areidentical in design. Only difference is that there are users in theproduction system.Any ideas?Thanks

Hi,
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...

Hi,
just started to write my first trigger for a view. Of course I got some errors, which I could could resolve except one.
Whenever I run my script I do get the following message:
Msg 213, Level 16, State 1, Procedure IO_Trig_INS_Zuordnung_Alles, Line 11
Insert Error: Column name or number of supplied values does not match table definition.
The Code where the error occurs according that message is the following:
CREATE TRIGGER IO_Trig_INS_Zuordnung_Alles ON Zuordnung_Alles

SET NOCOUNT ON
-- Check for duplicate Zuordnung. If there is no duplicate, do an insert.
IF (NOT EXISTS (SELECT Z.[Anlagen-Nr_Z]
FROM Zuordnung Z, inserted I
WHERE Z.[Anlagen-Nr_Z] = I.[Anlagen-Nr_Z]))
INSERT INTO Zuordnung

I did check on the columns serveral times, also I wrote them back with vba and used that but nothing helps. I would appreciate any help on possible errors in that code.

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

I am situation, where we have a table named as Project, columns for the table as follows:
Code:
------------------------------------------
ID | ClientCode | ProjectName
------------------------------------------
1 | AAA | Dubai Airport Phase I
2 | AAA | Dubai Airport Phase II
3 | ARC | Salala
4 | MIZ | UMBC Building
------------------------------------------
Now my task was, whenever a project name and other details being created, then a Folder will be created in a server itself in the path E:ProjectFolder in following way:
E:ProjectFolderAAAAAA1
E:ProjectFolderAAAAAA2
E:ProjectFolderARCARC3
E:ProjectFolderMIZMIZ4
You can see here Folder and sub-folder is being created with that following project - client code & ID
I used following trigger to do the same:
Code:
CREATE TRIGGER [dbo].[CreateFolderName]
ON [dbo].[Project]
after INSERT
AS
SET NOCOUNT ON
BEGIN
declare @chkdirectory as nvarchar(4000), @folderName varchar(100), @mainfolderName varchar(100)
declare @folder_exists as int
SET @mainfolderName = (SELECT ClientCode AS Project FROM INSERTED)
SET @folderName = (SELECT (ClientCode + cast(ID as varchar(10))) AS Project FROM INSERTED)
set @chkdirectory = 'E:ProjectFolder' + @mainfolderName + '' + @folderName
[code].....
This worked like a charm, now my next task is using same trigger, I have to create a BAT file inside that SubFolder - T-SQL for creation of BAT File as follows:
Code:
DECLARE @FileName varchar(50),
@bcpCommand varchar(2000)
SET @FileName = REPLACE('E:ProjectFolder[red](select ClientCode from INSERTED)[/red][red](select ClientCode + cast(ID as varchar(10)) from INSERTED)[/red]xcopy_'+ (SELECT cast(ID as varchar(10)) FROM INSERTED) +'.bat','/','-')
SET @bcpCommand = 'bcp "[red]SELECT 'xcopy "E:ProjectFolder' + clientCode + '" "10.0.0.35ProjectFolder" /T /E /I' FROM INSERTED[/red]" queryout "'
SET @bcpCommand = @bcpCommand + @FileName + '" -U SQLServerUsername -P SQLServerPassword -c'
EXEC master..xp_cmdshell @bcpCommand
Here I am not understanding how to insert the above T-SQL in the Trigger as well as the above T-SQL is not right, what's wrong in this?
Last query that will be included in the trigger is to execute the newly created bat file.
