T-SQL (SS2K8) :: Return Primary Key From (updated) Record Of Merge Statement
Apr 16, 2014
I'm using a Merge statement to update/insert values into a table. The Source is not a table, but the parameters from a Powershell script. I am not using the Primary Key to match on, but rather the Computer Name (FullComputerName).
I am looking on how-to return the Primary Key (ComputerPKID) of an updated record as "chained" scripts will require a Primary Key, new or used.As an aside: the code below does return the newly generated Primary Key of an Inserted record.
CREATE PROCEDURE [dbo].[usp_ComputerInformation_UPSERT](
@FullComputerName varChar(50) = NULL
,@ComputerDescription varChar(255) = NULL
,@ComputerSystemType varChar(128) = NULL
,@ComputerManufacturer varChar(128) = NULL
[code]....

We are getting data feed from Oracle database in our project. Everyday we will need to track if any rows got inserted/updated/deleted in the source and get that update right into our data warehouse.
Currently we are taking a dump of the required table (as it is) to our staging DB and comparing it with previous day data to track the changes (column by column comparison). This approach is working currently but has performance bottleneck. There is no tracking column (eg. last modified date or time) in source that will give us any idea of what got changed. Also there is no identity key or primary key in the source data.
Is there a way in SQL Server to get that inserted/updated records only instead of comparing column by column to track the changes?

I am inserting a record into a table that automatically generatesunique ids (i.e. Primary Key). Is there anyway to return this id. As Iam using this on ASP.net page and I really need the ID to update thepage with the new details.I think on mysql there is something called LAST_INSERT_ID which doesthis.

I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID
OR
Student.GradeLevel <> esis.GradeLevel
OR
Student.LegalName <> esis.LegalName
OR
Student.WithdrawDate <> esis.WithdrawDate
Student.SPEDFlag <> esis.SPEDFlag
OR
Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid,
.....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

I would like to have a 'counter' table which will hold the last used number and return a new number. This is my schema:
if object_id('tempdb.dbo.#Counter', 'u') is not null drop table #Counter
go
create table #Counter (
Id int not null
)
go
if exists (select * from #Counter)
update #Counter
set Id = Id + 1
output inserted.Id
else
insert into #Counter (Id)
output inserted.Id
select 1
If the table is empty it returns 1 else it returns the next number (Id + 1). But this query is not atomic (i guess...?) so it could evaluate that the #Counter table is empty and then try to insert into the table, but inbetween someone else executes the insert also. Could this query be rewritten with the merge statement so that the whole operation is atomic?

I have a stored procedure on a SQL Server 2008 database. The stored procedure is very simple, just a SELECT statement. When I run it, it returns 422 rows. However, when I run the SELECT statement from the stored procedure, it returns 467 rows. I've tried this by running both the stored procedure and the SELECT statement in the same SSMS window at the same time, and the behavior is the same. The stored procedure is:
USE [REMS]
GO
/****** Object: StoredProcedure [mobile].[GetAllMobileDeviceUsers] Script Date: 12/04/2014 */
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[Code] ....
When I do this in the same SSMS window:
exec mobile.GetAllMobileDeviceUsers
SELECT
ee.EmployeeID,
EmployeeName = LastName + ', ' + FirstName
FROM EmployeeInvData ee
--UNION
[Code] ....
I get two result sets. The first is 422 rows; the second is 467 rows. Why?

I have table Products and Orders that has the following columns:
table Products: ProductID, ProductName
table Orders: OrderID, ProductID, OrderDate, Quantity, Price
The Orders table contains orders placed on all the dates. I want to obtain a list of orders for a particular date, if there is no order for a product on the requested date, I want to return null values for the Quantity and Price fields.
I tried the following select statement:
select Products.ProductName, Orders.Quantity, Orders.Price from Products left join Orders on Products.ProductID = Orders.ProductID where Orders.OrderDate = '10/16/2004'
Where, there are a total of three products (A,B,C) in table Products. Product-C has no order on 10/16/2004, but I want it to return :
ProductName / Quantity / Price
Product-A 5 1.89
Product-B 6 2.43
Product-C null null
Obviously, my sql statement won't work becaue the where clause will filter out Product-C.
Could anyone help me figure out how to modify my sql code to get the resultset I want?
Thanks in advance.

Greeting.
I use OdbcConnection inside clr procedure, for getting data. If I use simple EXEC dbo.clr_proc - all is OK. If I use INSERT...EXEC I recive error message: Distributed transaction enlistment failed.
I set MSDTC security options for No Authentification and Allow inbound and Allow outbound, but it's no use.
Have this problem solution? May be, I must use another method to get my data?
P.S. Linked Servers and OPENQUERY is not applicable. Sybase not describe columns in stored proc result set and one stored proc may return different result set by params.
P.S.S. Sorry for bad english.

I have not yet succeeded in getting an aswer to this in a previous post, so I'll try again and rephrase the question
I have 2 fields, 1 called 'Created' the other 'Updated'
I would like to create a function, user procedure ,whatever in SQL something along the lines of...
FUNCTION myUID()
RETURN Date(Today)+Time(Now)+USERNAME
END FUNCTION
so that the value returned by the above pseudo code is something like '20080526T21:01:05.620SamL' where the date part is in yyyy0m0d format
I have got this working fine for the default 'Created' field but the calculated (and persisted) field comes up with something about being non-deterministic and refuses to play
Clearly something along these lines is a very straightforward requirement (I have it working fine in my 20+ year old database) , but have spent a week trying to get an answer (even from this forum) without success, so would be grateful for any help that you can provide me with to get round this barrier

I have database that holds column depicting various events and the last time that the event occurred.I query the database and I get a result like this:
Event Update Time
Event A 2014-10-14 00:35:00.000
Event B 2014-10-14 01:30:00.000
Event C 2014-10-14 00:35:00.000
Event L 2100-01-01 00:00:00.000..I would like to create another database to hold the various timestamps for each event. Some of these events happen every 2 minutes, others hourly, daily or monthly.I can query the source every minute. I do not want duplicate entries in the destination when the 'Update Time' has not been updated. Is it better to query the destination for the latest 'Update Time' value and only INSERT the new record when the time has been updated or just put a UNIQUE constraint on the Event and UpdateTime columns?

Hi -
apologies if this is not the right forum for this - I've searched a bit and this seems to be the best fit.
I have the following problem: I want to update records in a table that fit certain criteria. The way the insert logic works make sure that there will always be only one record that fits the criteria and I'd like to get the ID value of that record once the update went through. So here is what I tried:
1 UPDATE Timeslot
2 SET StartTime = @StartTime, EndTime = @EndTime
3 WHERE (ProfessionalID = @ProfessionalID) AND (ProviderLocationID = @ProviderLocationID) AND (RequestID IS NULL) AND (StartTime > @StartTime) AND
4 (EndTime < @EndTime);
5 SELECT SCOPE_IDENTITY()
My hope was that the select scope_identity would return the Timeslot ID of the row that was affected, but it doesn't. How do I get that row?
Thanks!!!
Oliver

I am trying to write a trigger that, on an update, will check to see if more than one record is being updated. If more than one record is being updated, rollback the transaction and print a message. If not, then commit the transaction and print an OK message.
My problem is I am having troubles writing this trigger. I will post my SQL trigger code so far.
I am new with Triggers, so any help or advice is appreciated.
Code:
CREATE TRIGGER trgPaperCheck
ON BOOK
AFTER UPDATE
AS
IF UPDATE(Paperback)
BEGIN
DECLARE @count AS INT
SELECT @count = COUNT(Paperback)
FROM Book
IF @count > 1
BEGIN
PRINT('Only one Book record can be updated at a time!')
ROLLBACK TRANSACTION
END
ELSE IF @count =1
BEGIN
PRINT('Paperback Updated')
COMMIT TRANSACTION
END
END

Is there a way to auto-update this field value to the getdate() value each time the record is "touched" by an UPDATE sql command?

I've gotten conflicting info about this in the past so I thought I'd try to get clarification.
When a record is deleted, I'm sure it fires the delete trigger. Does it also fire the update trigger?
Thanks
