Create Trigger That Prevent Order Being Processed If The Amount Is 0 In Storage


When i process a order in table Orders_t i would like to check in storage_t if we defenetly have it in storage. .... if we have it in storage, i decrease the "amount" by 1 ..(amount -1), and process the order. Otherwise it will return nothing.

This is what i´ve come up with so far:


CREATE TRIGGER checkInStorage
ON orders_t
FOR INSERT, UPDATE

AS
DECLARE
@tOrderId char(3),
BEGIN
SET @tOrderId = (SELECT orderId FROM INSERTED)

--check if the amount in storage

IF EXIST(SELECT amount FROM storage_t WHERE orderId = @tOrderId and amount >= 0)
BEGIN --if it return true, i update the storage by decrease the amount with one
UPDATE storage_t
SET (amount = amount - 1)
WHERE orderId = @tOrderId
END




this doesn´t work...

Trigger To Prevent Duplicates
Hi all,

I'm writing a trigger to prevent duplicates. I know that this can be done through primary key or unique constraints but in the real world my uniqueness is defined by 8 columns which is too a big an index to maintain on the primary / unique key.

If I create a table with 2 columns

CREATE TABLE Table1
(CentreCHAR(10),
Month CHAR(3)
)


Then create a trigger to prevent duplicates

CREATE TRIGGER trigger_Check_Duplicates
ON Table1
FOR INSERT, UPDATE
AS
-- This trigger has been created to check that duplicate rows are not inserted into AudioVisual table.
DECLARE @IsDuplicate INTEGER
-- Check if row exists
SELECT @IsDuplicate = 1
FROM Inserted i, Table1 t
WHERE t.Centre = i.Centre
AND t.Month = i.Month
IF (@IsDuplicate = 1)
-- Display Error and then Rollback transaction
BEGIN
RAISERROR ('This row already exists in the table', 16, 1)
ROLLBACK TRANSACTION
END

Then insert a row into the new table (no other data is in there)

INSERT Table1
VALUES('0691040176','AUG')

I get the Trigger error message that the row already exists. Why is this the case? I though that Table 1 (target table) would show no entries as it has no data - it should be a before image of the table and the inserted table should be an after image.


Please help!!!


Thanks

How To Separate Period Amount From YTD Amount
I'm creating a temporary table in a Sql 2005 stored procedure that contains the transaction amount entered in a period <= the period the user enters.
I can return that amount in my result set. But I also need to separate out by account the amounts just in the period = the period the user enters. There can be many entries or no entries in any period. I populate the temporary table this way:

SELECT
t.gl7accountsid,
a.accountnumber,
a.description,
a.category,
t.POSTDATE,
t.poststatus,
t.TRANSACTIONTYPE,
t.AMOUNT,
case
when t.transactiontype=2 then amount * (-1)
else amount
end as transamount,
t.ENCUMBRANCESTATUS,
t.gl7fiscalperiodsid

FROM
UrsinusCollege.dbo.gl7accounts a

join
ursinuscollege.dbo.gl7transactions t on
a.gl7accountsid=t.gl7accountsid

where
(t.gl7fiscalperiodsid >= 97
And
t.gl7fiscalperiodsid<=@FiscalPeriod_identifier)
And poststatus in (2,3)
and left(a.accountnumber,5) between '2-110' and '2-999'
And right(a.accountnumber,4) > 7149
And not(right(a.accountnumber,4)) in ('7171','7897')

order by a.accountnumber

Later I create a temporary table that contains budget information. I join these 2 temporary tables to produce my result set. But I don't know how to get the information for just one period. For example, if the user enters 99 as the FiscalPeriod_identifier, I need a separate field that contains only those amounts(if any) that were entered for each account in Period 99.

Can anyone help? It may be that I am not seeing the forest for the trees, but I can't figure it out.

Thanks very much.

Use Trigger To Number Each Order Line
I am wanting to set up a trigger on our SQL server 2000 to create a sequential order line number in the OrderDetails table for OrderID.

I will be inserting data from an OrderLinesAdd table into the OrderLines table but want the LineNumber field to be incremented by 1 for each group of orders grouped by OrderID that I insert into the table eg.

OrderID LineNumber
1 - 1
1 - 2
1 - 3
2 - 1
2 - 2
3 - 1
3 - 2

I have just started using SQL so am not sure how I go about writing the code for the trigger ? It would seem like I will need to use the Max function in the code.

Thanking you in advance.

Trigger Vs Uniqueness Constraint Order
Hi,
Can anyone tell me the order in which uniqueness constraints on indexes are enforced vs. when triggers are executed ? I have a unique constraint on an index and a trigger on the column on which the same index has been created. When a row is inserted, the trigger checks if the value for that column already exists in the table - if not, it inserts the row as is, else it gets the max() val of the column (based on another key column) and increments it by one, then does the insert. Creating an index across the two works fine, but if I set the Unique Values property for the index, subsequent inserts bomb out - yet there aren't any duplicates in the final table, as the trigger ensures this. Anyone got any ideas on this? My deduction is that the uniqueness constraint gets enforced before the trigger gets executed, but at the same time this *seems* illogical, as the row has not been inserted into the table at the point where the trigger is executed.

Regards,
Jon Reade.

Order Of Records In The INSERTED/DELETED Tables In A Trigger
We have an app that uses triggers for auditing.  Is there a way to know the order that the records were inserted or deleted?  Or maybe a clearer question is....  Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record?  The order of these is important to our auding.

Can't Install IBM Tivoli Storage Manager Server On Windows 2003 X64 Storage Server, How Can I Fix The Pkg?
I am a Windows developer for the IBM Tivoli Storage Manager Server (TSMS) product.
Our product installation is built with InstallShield and uses the Windows Installer.
 
On a new installation of Windows 2003 x64 Storage Server R2, at a customer's site, the TSMS product fails to install.
The install of the OS has version 3.01.400.3959 of the Windows Installer and I see no newer version that installs.
 
Part of our product is 32 bit (console) and another part is x64 (server).
When installing I can see that the install's default is being redirected/reset to C:Program Files (x86)TivoliTSM after it is explicitly set by a custom action to ..Program Files.. . I further observe that our custom actions to write 64 bit registry entries are being refused.
 
    REGSAM samMask = KEY_ALL_ACCESS;
    if ( regIsWow64Process () ) samMask = samMask | KEY_WOW64_64KEY;
    lStatus = RegCreateKeyEx( hLocalConnectKeyRoot,
                              szSubkey,
                              0L,
                              NULL,
                              REG_OPTION_NON_VOLATILE,
                              samMask,
                              NULL,
                              hKey,
                              &dw ) ;
The above fails to create the key.
 
We have tried four versions of our TSMS spanning many changes but the install acts the same.
This does not happen on any other Windows OS we test on but we do not test on Windows 2003 Storage Server R2 being that it is an OEM product. We did test on Windows server 2003 R2 x64 and do not see this problem.
 
Do you have any suggestions on how to tackle this problem?
I have full installation traces but can only see that the registry work is being refused. I can't see why.

Run Report Multiple Times Programmatically In Order To Create A Table Of Contents
Hi,

I have been working through how to generate a Table of Contents (page numbers need to be from a pdf format) in the front of a very large price list report.  I am so close to having everything the way I need it. In fact, I can get the desired results by manually doing the following:

1.  Run the report in Report Server - (custom assembly writes the preview page numbers to a TOC database table)

2.  Truncate the database table - (I'm not sure why I have to do this, but it is the only way I can get  the new values created in step 3 to write to the database properly)

3.  Export to pdf in Report Server - (writes the correct pdf page numbers to the TOC table)

4.  Refresh the report in Report Server

5.  Export to pdf again in Report Server.

Of course, I can't ask my users to do this.  I want my users to be able to just do step 5 and get the desired PDF.  I have found several postings and they all say things like "run the reports 3 times", but don't say how to do this, or give any reference web sites or examples.  I know here's a way to do it programmatically, but I'm having a difficult time figuring out how to do it.  I do not want to render the report to the user until the pdf has the correct page numbers in my Table of Contents (step 5).

Any suggestions would be greatly appreciated.

Thanks in advance,
Amy Bolden

Create Trigger Help?
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

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.

Then the OUTPUT OF the Product_Mst shoub be..

ELSE...

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.

Create Trigger For Relationship
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!!!!!!!!!!!!!!!!

How Can I Create This Update Trigger???
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...

How To Create A Trigger To Update A Field
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.

Create Trigger To Use AFTER DataAdapter.Update()
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

Trigger To Create A Table On A Row Insertion
Hi there

I have a relatively noobish query and I am hoping to get a solution to it.

Heres the query in a nutshell.

I have a 'Type' table which has a 'TypeName' varchar attribute. So when I do a row insert into this Type table, I want a new table created with the value I insert into the 'TypeName' column as the table name.

For example If i insert 'xyz' into the 'Type' table for the 'TypeName' column. I wish for a trigger to fire which will create a table 'xyz' with some set attributes. I am really new to SQL Server and my preliminary googling left me disheartened with the results. So here I am.

I hope I was clear in the way I expressed my doubt and also that the people here might be able to help me out in this quest.
