My company has decided that all CRUD operations will be done via stored procedures. I am in the process of coming up with a strategy for handling transactions. Before I begin my design, I was wondering if I will be better off keeping my transaction logic completely in my stored procedures or would I be best served by surrounding calls to my stored procedures using ADO.NET transactions to handle the transaction logic?Thanks
View 6 RepliesI have a simple question: Can I have two or more stored procedures that begin transactions but the last stored procedure will commit all transactions if there was no error?
In other words, I have a stored procedure that performs some legacy stuff. I do not want to rewrite that logice, execpt I am putting it into a Stored Procedure since it currently is embedded SQL.
To support newer functionality, I am writing data to additional new tables. However, I do not want the *new* things to occur if there is an error. This is easy enough, I dont call the Stored Procedure for the new functionality if there was an error. However, if there was not an error and the newer stored procedure is called AND there is an error in the new stored procedure, I want to ROLLBACK the changes from the proceeding stored procedures.
To my understanding, I can name transactions but that is only to indicate in the logs what transactions have failed.
I thought about not using transactions for any of the individual stored procedures and calling them from a main stored procedure. The main stored procedure will have a BEGIN TRY and an END TRY (I am using SQL Server 2005) and at the top (right after the try) I will have a BEGIN TRANSACTION. In the BEGIN CATCH I will have a ROLLBACK and at the end I will have a COMMIT. If any of the stored procedures fail at any point it will cause the catch to occur thus rolling back all of my transactions. This would be the easiest way but I still need to deal with the question of, "What happens if any single stored procedure is called?" I guess I could have try and catches in each individual stored procedure for that.
I just want to make sure I am not overlooking something simple. I think I have the right idea by doing it this way I mentioned above. Because this is critical billing processing I just want to have some reassurance that this would work.
Thank
I have been having a bit of trouble creating a sql schema creation script (using sql server 2005) with generic stored procedures. I am generating the script from an xslt transform, so it is all in one document. The intent is that either everything works (schema creation, tables, constraints, procedures, and triggers) or the entire thing will be rolled back.
The problem I am having is that I can not find a way to put more than one stored procedure inside of a transaction statement, much less having all of the create statements needed within the same transaction. As far as I can tell the GO statement is needed between stored procs, but this statement appears to commit the preceding create <object> statement - breaking my atomic transaction.
Does anyone know a way around this or a way to put multiple procedures/triggers in the same transaction?
I want to know the differences between SQL Server 2000 storedprocedures and oracle stored procedures? Do they have differentsyntax? The concept should be the same that the stored proceduresexecute in the database server with better performance?Please advise good references for Oracle stored procedures also.thanks!!

This Might be a really simple thing, however we have just installed SQL server 2005 on a new server, and are having difficulties with the set up of the Store Procedures. Every time we try to modify an existing stored procedure it attempts to save it as an SQL file, unlike in 2000 where it saved it as part of the database itself.
Thank you in advance for any help on this matter
Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.
For example, even this simple little guy:
CREATE PROCEDURE BOB
AS
PRINT 'BOB'
GO
Gets created as a system stored procedure.
Any ideas what would cause that and/or how to fix it?
Thanks,
Jason
Good afternoon,
I was checking how Microsoft was doing something on stored procedures and I've noticed something interesting (or not) in their AdventureWorks sample database. I've noticed that their stored procedures are encapsulated in transactions such as this:BEGIN TRY
BEGIN TRANSACTION; -- <SOME SQL HERE>
END TRY
BEGIN CATCH
-- Rollback any active or uncommittable transactions before
-- inserting information in the ErrorLog
IF @@TRANCOUNT > 0
BEGIN
ROLLBACK TRANSACTION;
END
EXECUTE [dbo].[uspLogError];
END CATCH;
For the more I can understand what they are doing here I do have a question regarding the way SQL Server executes this procedure and the eventual overhead of it. I'm saying this because, as far as I know, when we execute a stored procedure it runs as a whole transaction itself. Not being very proficent with transactions, I find myself with the question: Isn't this a double transaction? If so, isn't this causing unecessary overhead on the database server, consequently in the database itself? Or is this pretty much the only way to do error handling without a roundtrip to the caller (e.g. Data Access Layer)
I'm trying to learn more about transactions and error handling using SQL Server so every help is valuable.
Best regards,DBA

The transaction does not rollback when any errors occur at all. Any advice/help?
Ive never used transactions before but i would like to start using them within stored procedures.
I have some questions about them and how roll backs function.
i have had a go a writing a basic procedure with a transaction
** updated {with Code wrap }
Code:
CREATE PROCEDURE TransferMoney
(
@Account1 Int,
@Account2 Int,
@myValue Numeric(18),
@myValue2 Numeric(18)
)
AS
-- STEP 1: Start the transaction
BEGIN TRANSACTION
-- STEP 2 & 3: Issue the Insert statement, checking @@ERROR after each statement
Insert Into Bank (Balance) Values (@MyValue)
WHERE AccountID = @Account1
-- Rollback the transaction if there were any errors
IF @@ERROR <> 0
BEGIN
-- Rollback the transaction
ROLLBACK
Return
END
Insert Into Bank (Balance) Values (@MyValue2)
WHERE AccountID = @Account2
-- Rollback the transaction if there were any errors
IF @@ERROR <> 0
BEGIN
-- Rollback the transaction
ROLLBACK
Return
END
-- STEP 4: If we reach this point, the commands completed successfully
-- Commit the transaction....
COMMIT
now have i used the
IF @@ERROR <> 0 correctly?
i want this transaction to only happen if the if both statement are true, stopping data insertion Errors when transfering from one account and adding to another.
any thoughts you have will be fantastic

Greetings,
We are using peer-to-peer transactional replication. When using the default agent profile, the replicator stops processing commands when it encounters an error. It appears to keep trying to apply the command that caused the error and essentially hangs on that command. We have changed our agent profiles to "Continue on data consistency errors" - not the kind of option to give you a warm fuzzy feeling but we just don't know what else to do.
Where are the commands that cause errors stored within the replication environment? Can they be individually viewed, edited, and/or deleted? We would like some alternative to "continue on data consistency errors."
Thanks,
BCB
I have a quick question.
I need to execute some stored procedures in certain steps... all performing some inserts/updates
What i need is, a mechanism, by which i can roll back to the previous state if i encounter an exception (either in the app or SP)
so, if the my first two SP execute fine, perform their functionality like insert/update, and the third one fails...
how can i roll back to the initial state in ASP.NET.
would appreciate any info.
or redirection to the the location where i can look up some info on that.

How do I search for and print all stored procedure names in a particular database? I can use the following query to search and print out all table names in a database. I just need to figure out how to modify the code below to search for stored procedure names. Can anyone help me out?
SELECT TABLE_SCHEMA + '.' + TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID, S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName', T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID FROM [Item].ItemDetails I INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID FROM [Item].ItemDetails IOr something like that... Any thoughts?

I have MSSQL 2005. On earlier versions of MSSQL saving a stored procedure wasn't a confusing action. However, every time I try to save my completed stored procedure (parsed successfully ) I'm prompted to save it as a query on the hard drive.
How do I cause the 'Save' action to add the new stored procedure to my database's list of stored procedures?
Thanks!
Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated
We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database.
For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product.
I can't update the sys.Objects or sys.Procedures views in 2005.
What effect will this flag (is_ms_shipped = 1) have on my stored procedures?
Can I move these out of "System Stored Procedures" and into "Stored Procedures"?
Thanks!
Hello friends......How are you ? I want to ask you all that how can I do the following ?
I want to now that how many ways are there to do this ?
How can I call one or more stored procedures into perticular one Stored Proc ? in MS SQL Server 2000/05.
Hello
I'm start to work with SSIS.
We have a lot (many hundreds) of old (SQL Server2000) procedures on SQL 2005.
Most of the Stored Procedures ends with the following commands:
SET @SQLSTRING = 'SELECT * INTO ' + @OutputTableName + ' FROM #RESULTTABLE'
EXEC @RETVAL = sp_executeSQL @SQLSTRING
How can I use SSIS to move the complete #RESULTTABLE to Excel or to a Flat File? (e.g. as a *.csv -File)
I found a way but I think i'ts only a workaround:
1. Write the #Resulttable to DB (changed Prozedure)
2. create data flow task (ole DB Source - Data Conversion - Excel Destination)
Does anyone know a better way to transfer the #RESULTTABLE to Excel or Flat file?
Thanks for an early Answer

Hi,
Do you know how to write stored procedures inside another stored procedure in MS SQL.
Create procedure spMyProc inputData varchar(50)
AS
----- some logical
procedure spMyProc inputInsideData varchar(10)
AS
--- some logical
--- go
-------
I am writing a set of store procedures (around 30), most of them require the same basic logic to get an ID, I was thinking to add this logic into an stored procedure.
The question is: Would calling an stored procedure from within an stored procedure affect performance? I mean, would it need to create a separate db connection? am I better off copying and pasting the logic into all the store procedures (in terms of performance)?
Thanks in advance

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?
i have created the folowing function but keep geting an error.
Only functions and extended stored procedures can be executed from within a function.

(SELECT SUM(TRANSACTION_VALUE)
FROM EVENT_DATA WHERE PLAYER_ID=@ID AND TRANSACTION_TYPE=1
GROUP BY PLAYER_ID),0) AS WINNINGS FROM PLAYERS P
undefined P
The first returns a percentage for player wins, the second gives me a photo and sums the player winnings
I would like to combine the results so I can get the percentage and wininngs in one query, in another matter all together I would like create a procedure like the first but instead of returning only one player, I would like to return the percentage for each player
Thanks in advance for any light you can shine on this.
I have a question about stored procedures, Is it better to use stored procedures even if I only use it once at my site? Or is it better to write the sql-part directly in the sqldatasource?
And am I forced to create two different stored procedures even if they are exactly the same except the "Where-part"?
Now I have around 40 stored procedures, and quite many of them looks the same except the where-part...

Hi,
Can anyone help me. I've created a stored procedure in sql server and I'm trying to run it from my asp.net page. On Database Explorer I can't see it, or any for that matter, however I can see tables in the same schema.
Also I can't see it when I build a table adapter either.
Can anybody help?

Hi,how can I use stored procedures in asp.net. The stored procedure itselve is defined on the sqlserver and works fine.Actual I found out that in my asp.net 2-surrounding there can be the adofunction disabled.I tried to use it with dimension of a new SqlConnection but I'm woundering why within a visual basic part I don't get the codecompletion whenI use the dimensioned object combined with commands.Regards,Ruprecht Helms
