Create Procedure Or Trigger To Auto Generate String ID

Feb 20, 2004

Dear everyone,

I would like to create auto-generated "string" ID for any new record inserted in SQL Server 2000.

I have found some SQL Server 2000 book. But it does not cover how to create procedure or trigger to generate auto ID in the string format.

Could anyone know how to do that?? Thanks!!

From,

Roy

Creating Trigger To Auto Set Create/modify Dates

Jul 20, 2005

Hi,I'm a newbie to sql server and this may be a really dumb question forsome you. I'm trying to find some examples of sql server triggers thatwill set columns (e.g. the created and modified date columns) if the rowis being inserted and set a column (e.g. just the modified date column)if the row is being updated.I know how to do this in oracle plsql. I would define it as a beforeinsert or update trigger and reference old and new instances of therecord. Does sql server have an equivalent? Is there a better way to dothis in sql server?Thanksericthis is what i do in oracle that i'm trying to do in sqlserver...CREATE OR REPLACE TRIGGER tr_temp_biubefore insert or updateon tempreferencing old as old new as newfor each rowbeginif inserting then:new.created_date := sysdate;end if;:new.modified_date := sysdate;end tr_temp_biu;

Getting The Auto Value From Trigger

Jan 29, 2001

Hi all,

My requirement is to get the autoincrement column once a new row is inserted, we need the autoincrement value to update other tables, at present I am using an insert trigger in which I am extracting the autoincrement column from the 'inserted' table, but how far this work perfectly when multiple users insert simultaneously. Can any of you suggest me the best way to extract the actual value inserted.

Now the scenario is :

sp which insert a row
Begin tran
insert ...
select @returnKey = (select retkey from #temptab)
drop #temptab
Commit Tran

Trigger on insert

insert idcolumn into #temptab select autokey from inserted


If user A & B inserts row exactly at same time, will this method return the exact auto value what A and B have inserted to them respectively.

Thanks in Anticipation

SQL Trigger And Auto Email

Oct 16, 2006

Hi,

I have a trigger for a table which stores email information generated from an ACCESS form. The trigger should send an auto email response to users who submitted an email to request for their password (we have forgetful users!). There is something wrong with my trigger because the auto email is sent out with a blank body... I will appreciate any advice!

Thank you!

My trigger:
CREATE TRIGGER tr_SendPassword ON PIPEmail
FOR INSERT
AS
DECLARE @Password varchar(100)
DECLARE @EmailAddress varchar(100)
DECLARE @message varchar(100)
IF (select count(*) from inserted) = 1
BEGIN
IF exists (SELECT * FROM inserted
WHERE Subject = 'Forgot my password')
BEGIN
select @Password = 'We received an email request from you for your password. Your password for SAR Search is: ' + UserRole.Password,
@EmailAddress = [User].Email
from UserRole
join inserted on UserRole.WindowsUser = inserted.WindowsUser
join [User] on [User].WindowsUser = UserRole.WindowsUser

exec master.dbo.xp_sendmail @recipients=@EmailAddress,
@subject='SAR Search password request',
@message=@Password
END
END

Auto Create Statistics / Indexes

Sep 1, 2000

Hi everyone,

I know that statistics called _WA_... are created on tables when auto create statistics is set on a database. Is this an indication that queries against the table would perform better if indexes were created on the columns in question? (The tables I'm interested in optimising are used equally for transactional querying and reporting)

Thanks for any replies!

Auto Create History Tables And Triggers

May 30, 2007

For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.

We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.

The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:

1) Queries system tables to retrieve table schema for @TableName parameter

2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.

3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

Create Trigger Help?

Sep 14, 2004

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

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

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.

The Create trigger is submitted by itself through the sqlcommand.executenonquery() method.

Create Trigger On Sysobjects

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.
