Error Handling/ Stored Procs
Jul 8, 2005
Hi, I'm doing some fairly basic updates with stored procedures. 99% of them affect one row. I've jsut discovered that I can't get the value of @@rowcount and @@error to return as output parameters (if I check one, the other one gets reset!). My theory is then to return the rowcount and if it's not = 1, then I know I've had a problem. If I begin a transaction in vb.net and call each proc in the required order and check each step that rowcount = 1, is this a reliable method of ensuring no errors have occurred?Thanks.

Can anyone let me know the prefered method for handling stored procedure errors. I usually trap the error in the stored proc and then return a value using an output parameter
e.g stored proc
if @@error <> 0 beginset @returnValue = -1returnend
c#com.Parameters.Add("@returnValue", SqlDbType.Int).Direction = ParameterDirection.Output;con.Open();com.ExecuteNonQuery();
int result = (int)com.Parameters[0].Value;
if (result == -1){//throw exception}else{//do whatever}

I would like to capture any errors thrown by linked server in my stored procedure, How do I do this? eg: Select statement in sp to remote server fails if login credentials were changed for some reason on remote server. @@error is not able to capture this error and stored procedure is terminated when this type of error occurs.

I am kinda curious how the rest of you are doing your error handling inside your activation stored procedures...best practices says you should not rollback the part of your transaction that receives the record off of the queue...but using a try...catch block will only allow you to rollback the entire transaction. I tried using savepoints and starting the try...catch after the savepoint and the proc still gives me the error: "
The current transaction cannot be committed and cannot be rolled back to a savepoint. Roll back the entire transaction." when the error scenario is encountered.
I tried using @@Error and checking for errors at the statement level which would allow me to do a partial rollback, but the type of errors I receive (i.e. invalid data types etc) are aborting the entire batch instead of passing the error and continuing.
Can other people on this forum using service broker give me an idea of how you are getting around this issue?

Is there a way to namespace groups of stored procs to reduce confusion when using them?
For C# you can have ProjectName.ProjectSection.Classname when naming a class. I am just wondering if there is a way to do the same with SQL stored procs. I know Oracle has packages and the name of the package provides a namespace for all of the stored procs inside it.

I have an application where I am bcping a file into a holder table and then looping through each of the rows in that table to add it into the main table for the app. If the data is improperly formatted (ie someone accidently enters 39.Y6 instead of 39.66), we still want to keep it in the system, so we can update the bad fields manually and then import it into the system and keep going through the loop so that if there are 50 rows to import and only one of them is bad, the other 49 will still get imported fine.
I am putting each field from the holder table into a variable and passing them into an existing stored procedure that updates the main table. I had originally checked each one of those variables that had to be numeric or a date to make sure that it was correct before passing them into the procedure but there are about 30 fields so this made the application run unacceptably slow. I then just checked the @@Error value after passing them into the stored procedure (tried after the sp and after the INSERT statement inside the sp) to get that this row didn't insert correctly and move onto the next one. The problem is that the "Error converting data type varchar to numeric" doesn't seem to be handled by the error handling and just bombs the whole thing, so none of the subsequent rows or processing is done.
Is there any way to handle this error and continue the processing without the whole stored procedure crashing? The data entry is being outsourced to India (grrr...), so I don't have any control over checking the data when they enter it and have to do it from within my application on the database side.

I have a stored proc that loops through records using a cursor. If during the loop an error occurs i need to trap the error and write it to a log file.
Error handling needs to be placed in the update and insert sections and the error that occurs needs to get recorded along current row from the cursor.
Here is the code:
declare
@tier_id int,
@tier_desctext varchar(50),
@tier_shortdesc varchar(50),
@long_name varchar(50),
@short_name varchar(50),
@rec_count int
--Cursor for UES data
DECLARE cr_ues_tier INSENSITIVE CURSOR
FOR SELECT DISTINCT tier_id, tier_desctext, tier_shortdesc
FROM "dbsourcedayoldprod".ues.dbo.Tiers
OPEN cr_ues_tier
--Select cursor values into local variables
FETCH NEXT FROM cr_ues_tier INTO @tier_id, @tier_desctext, @tier_shortdesc
WHILE (@@FETCH_STATUS <> -1)
BEGIN
--Set Data Mart variables
SELECT @long_name = long_name, @short_name = short_name
FROM uesrpt..coverage_level
WHERE ues_tier_id = @tier_id
--Set the record counter
SET @rec_count = (select ues_tier_id from uesrpt..coverage_level where ues_tier_id = @tier_id)
--Are there exsisting records if so go to the update section
IF @rec_count <> 0
--Update Data Mart values if they have changed
BEGIN
IF @long_name <> @tier_desctext
OR (@long_name IS NULL AND @tier_desctext IS NOT NULL)
OR (@long_name IS NOT NULL AND @tier_desctext IS NULL)
OR @short_name <> @tier_shortdesc
OR (@short_name IS NULL AND @tier_shortdesc IS NOT NULL)
OR (@short_name IS NOT NULL AND @tier_shortdesc IS NULL)
UPDATE uesrpt..coverage_level
SET long_name = @tier_desctext,
short_name = @tier_shortdesc
WHERE ues_tier_id = @tier_id
END
--Rows don't exsist in the Data Mart - Insert new rows
ELSE
INSERT INTO uesrpt..coverage_level (ues_tier_id, long_name, short_name)
SELECT @tier_id, @tier_desctext, @tier_shortdesc
--Get next row from UES cursor
FETCH NEXT FROM cr_ues_tier INTO @tier_id, @tier_desctext, @tier_shortdesc
END
CLOSE cr_ues_tier
DEALLOCATE cr_ues_tier
GO
Any help is appreciated.
Thanks.

Hi all,
I have a huge stored procedure. part of the query is, the cursor is open and it consist of the implementation for subquery, I want to do an implementation if this subquery return more than one value, catch the error, but continue the cursor operation.
my SQL procedure part looks like:
---code to open the cursor here
WHILE @@FETCH_STATUS=0
BEGIN
SELECT @attachmentCount=count(metaDataID)
FROM View_1
WHERE parentMetaDataID='' + ( SELECT metaDataID
FROM View_1
WHERE metaDataStorageID = @metaStorageID AND parentMetaDataID='0') + '' AND
metaDataContentTypeID=@metaDataContentTypeID
--error handling
DECLARE @err int
SELECT @err = @@error
IF @err <> 0
BEGIN
FETCH NEXT FROM CursorDataStorageID INTO @metaStorageID
CONTINUE
END
FETCH NEXT FROM CursorDataStorageID INTO @metaStorageID
END
-----------------
when I execute this query in SQL management studio, it does return me the no of rows with the msg:
Msg 512, Level 16, State 1, Procedure sp_AdvanceSearchHugeExecution, Line 522
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
But when the stored procedure is called from the within the code ASP.Net, to fill the dataset, I get an exception.
my C# code is simple to fill the dataset using data adapter in try catch block.
Can anyone please suggest how will I able to fill dataset successfully overcoming this mesg?
Thanks a lot.

OK, i'm trying to do some error checking on stored procedures and amfollowing the advise in Erland Sommarskog's 'Implementing ErrorHandling with Stored Procedures' document.Can anybody help with my stored procedures and why it keeps erroring atthe '-- Create new Address Detail stage'?

I am a little confused about something and I am hoping that someone out there has some insight.
Within a stored procedure, I have error handling code just after an INSERT statement. the error handling code basically checks @@ERROR, and if non-zero, logs a message to the NT Event Log. One of the things I want to be able to handle is if the transaction log on the database is full, and the INSERT fails for this reason. However, it appears that for this particular situation (and others I've seen in the past), the stored procedure aborts at the INSERT statement. Never makes it to the error handling code. Is there any way to control this behaviour?
I really need to put in place a failure scenario, if the insert fails, but i can't do that if the stored proc. just aborts on certain types of insert failures.

I have a Stored Proc that is called by a SQL Job in SQL Server 2000. This stored proc deadlocks once every couple of days. I'm looking into using the @@error and try to doing a waitfor .5 sec and try the transaction again. While looking around google I've come across a few articles stating that a deadlock inside a Stored Proc will stop all execution of the stored proc so I will not be able doing any error handling. Is this true? Does anyone have any experience that could help me out?
I know the best solution would be to resolve why I get a deadlock. We are currently looking into that but until we can resolve those issues I would like to get some type of error handling in place if possible.
Thank you,
DMW

HI,
CREATE PROCEDURE PROC1
AS
BEGIN
SELECT A.INTCUSTOMERID,A.CHREMAIL,B.INTPREFERENCEID,C.CHR PREFERENCEDESC
FROM CUSTOMER A
INNER JOIN CUSTOMERPREFERENCE B
ON A.INTCUSTOMERID = B.INTCUSTOMERID
INNER JOIN TMPREFERENCE C
ON B.INTPREFERENCEID = C.INTPREFERENCEID
WHERE B.INTPREFERENCEID IN (6,7,2,3,12,10)
ORDER BY B.INTCUSTOMERID
END
IF I AM USING THIS PROC AS I/P TO ANOTHER PROC THEN IT GIVES NO PROBLEM AS I CAN USE ?
CREATE PROCEDURE PROC2
AS
BEGIN
CREATE TABLE #SAATHI(INTCUSTOMERID INT,CHREMAIL NVARCHAR(60),INTPREFERENCEID INT,CHRPREFERENCEDESC NVARCHAR(50))
INSERT INTO #SAATHI
EXEC PROC1
ST......1,
ST......2,
END.
BUT IF , I USE ANOTHER PROC SIMILAR TO THE FIRST ONE WHICH GIVES SLIGHTLY DIFFERENT RESULTS AND GIVES TWO SETS OF RESULTS,THEN WE HAVE A PROBLEM,HO TO SOLVE THIS :-
CREATE PROCEDURE MY_PROC
AS
BEGIN
SELECT A.INTCUSTOMERID,A.CHREMAIL,B.INTPREFERENCEID,C.CHR PREFERENCEDESC
FROM CUSTOMER A
INNER JOIN CUSTOMERPREFERENCE B
ON A.INTCUSTOMERID = B.INTCUSTOMERID
INNER JOIN TMPREFERENCE C
ON B.INTPREFERENCEID = C.INTPREFERENCEID
WHERE B.INTPREFERENCEID IN (23,12,10)
ORDER BY B.INTCUSTOMERID
END
SELECT A.INTCUSTOMERID,MAX(case when A.intpreferenceid = 23 then '1'
else '0' end) +
MAX(case when A.intpreferenceid = 12 then '1'
else '0' end) +
MAX(case when A.intpreferenceid = 10 then '1'
else '0' end) AS PREFER
FROM CUSTOMER
GROUP BY A.INTCUSTOMERID
ORDER BY A.INTCUSTOMERID
END
WHICH NOW GIVES ME TWO SETS OF DATA , BOTH REQUIRED THEN HOW TO USE ONE SET OF RESULTS AS I/P TO ANOTHER PROC AND OTHER SET OF RESULTS AS I/P TO YET ANOTHER PROC .
CREATE PROCEDURE PROC2
AS
BEGIN
CREATE TABLE #SAATHI(INTCUSTOMERID INT,CHREMAIL NVARCHAR(60),INTPREFERENCEID INT,CHRPREFERENCEDESC NVARCHAR(50))
INSERT INTO #SAATHI
EXEC MY_PROC
ST......1,
ST......2,
END.
BUT, HERE I WANT TO USE FIRST DATASET ONLY , HOW TO USE IT ?

i don't think i can do justice to how utterly stupid that stored procedure is
read the comments and have a laugh
one of the points made was that stored procedures are bad
this twigged something in my memory, so i dug around in my bookmarks, and sure enough, here's another decent discussion about stored procs --

Hey guys.
I am wondering if it is possible to execute an .exe from a stored proc. I have an application that calls a stored proc and I am wanting for that stored proc to call up an app to show certain results. I have no way of doing this on the application itself as I dont have the source code. So, since I do have access to the SQL I am wondering if it could be done there.
Thanks

First off, this is a cross post which is also located here:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=34073
Now, with the following stored procs and UDF, the Result is NULL and I cannot figure out why.
What I am doing is calling a stored procedure pass in an OUTPUT variable of type float. This stored proceudre then calls a different stored procedure passing the same OUTPUT variable of type float. The second stored procedure then calls a UDF passing in two variables to be multiplied ans this should set the OUTPUT variable to the result.
The UDF does return the correct result to the interior stored procedure, but the interior stored procedure does not pass the value back to the original stored procudure resultint in a Result value = NULL.
The code is below, just copy / past, execute and you will see exactly what I mean.
Any thoughts?

I am trying to improve my SQL and reduce the number of connections my website is making to the server.
Currently I have a stored procedure that gets all the games (and their details) for a single user which works fine which uses a WHERE userid = @userid which is an Int value.
I now need to create a new procedure which brings back the to all their "friends" (again by their userid). How is it best to do this? I originally tried to do a WHERE userID IN (@userid) but was unable to work out what variable type to use for @userid.
Is it best to do a single query in this way or is there a way to use the existing SP, loop through the collection of userids and join the result together into a single set to return? If an IN is the best route, what is the correct datatype for the variable?

Hi all!
I am not an expert in Stored Procs. I would like to build one for a product list that would return a default value without using output parameters, if possible. Ultimately, I wouldn't be opposed to it.
It currently looks like this:
CREATE PROCEDURE ProductsByVendorNo
(
@VendorNum nvarchar(24)
)
AS
SELECT
P.ProductID AS ProductID,
P.ProductShortName AS ProductName,
P.ProductDesc AS ProductDesc,
U.UnitDesc AS Unit,
P.VendorProductNumber AS VendorNumber,
V.VendorName AS VendorName,
P.Price AS Price,
P.ImageThumb AS ImageThumb
FROM
tblProducts AS P
INNER JOIN tblUnitCodes AS U ON P.UnitCode=U.UnitCode
INNER JOIN tblVendors AS V ON P.VendorID=V.VendorID
WHERE
V.VendorsVendorNo = @VendorNum
AND P.Inactive = 0
ORDER BY
ProductName,
VendorNumber
I would like for it to return a default, constant value for the URL in the ImageThumb field, if this one is empty. I could not find good documentation of how to use IF statements for this case, i.e. to alter the return of just one field.
Suggestions?
Any input is highly appreciated.
Thanks in advance,
Mili Skikic

I am trying to set up a DTS package that selects data from one table on server A into another table on server B. I want to do a select statement that will do the following:
select store_name
from store (server A)
where date_created >= (select max(date_created) from store (server B)
I use EM 7.0 to manage all of my extracts, however, the data is moving from a Syabase (adaptive Server)onto another Syabase(adaptive server) machine.
Unfortunately, there is no functionality for a linked server connection.
I tried the following, (which doesn't error out), but is not displaying the source columns in the destination tab of the DTS package when setting up the transformations.
declare @maxdate datetime
exec serverB.dbo.sp_max_date_from_store @maxdate
select store_name
from store --(server A)
where date_created >= @store
Any help or suggestions would be greatly appreciated!

Ok, I've read somewhere(which I'm looking for again : ) that said that there are errors like DeadLock that kills the execution of a stored proc and there are other errors that do not necessarily kill the rest of the execution of the stored proc. Is that true? If so does anyone have any links I can read. What I'm seeing is a bad id in the foreign key and I think what is happening is that there was a unique constraint error on the first insert but the stored proc continued executing and used the bad id later on in the stored proc.
I do know I can use the @@error and will start using it but I need more proof to agree or not agree with my theory.
Thanks ahead of time for any information you can give me either way.

Hi all.
First post on here, so please excuse any ignorant parts of my question :)
We've recently had to migrate an application from one server to another, and had lots of problems getting it to work (NT4/SS7 -> 2K3/SS2K5). After much digging around I found the info on SQL server 2k5 changing the SUSER_NAME to SUSER_SNAME (I think from reading the change was actually from SQL Server 2000 - that correct ?).
Anyway I updated some of our stored procedures to correct that issue, and things *seem* to be working again (<-- famous last words, I know :eek: ), but I've been trying to find details of any other changes, particularly command changes, that I may need to make to our stored procedures.
To be honest I've found the info on Microsoft's main site and technet site next to useless - all seems to discuss very generic high-level procedures for database migration etc.. I didn't even find the SUSER change on there.
Could anyone point me to some useful information on other changes to look out for (within the SP's) ??
Thanks in advance for your help, and for taking the time to read this :beer:
