Best Practices: Recording Error Information (Beyond ErrorCode and ErrorColumn)

I'm sorry for asking this, as I'm sure tha the answer is in one of the 208 matches I found searching on "ErrorCode". Unfortunately, this project is overdue and I need a solution fairly soon.

I should add that I've only been developing in SSIS since August 2007.

I have a complicated package, loading about 17 outputs of the XML Source into staging tables. I have been using the error outputs of any standard components I use, out of faith that, if Microsoft provided them, then they should be useful for something. I've been directing all of the error outputs for one of the 17 "tables" from the XML Source into a Union All, and then into an "Error staging table", for each of the 17 outputs. This table includes all of the possible columns, but permits nulls for all of them. It also incldues the ErrorCode and ErrorColumn.

Unfortunately, if these latter two are useful for anyting, I haven't found it yet.

Right now, working with our first "mostly real" data, I'm getting 100% of my input rows written into error tables. Unfortunately, the information in the tables are of limited use in determining what went wrong. For instance, the ErrorColumn seems only to be populated if there was a specific error with a specific column. The Lookup component, doesn't seem to populate ErrorColumn, even if only one column was used for the lookup! No information about the component producing the error output is supplied in the error output, either, which makes it difficult to determine which of the five or so possible error outputs is the one that produced the particular error row.

This proves that I'm missing something simple. How do people handle errors? In my custom components, I learned to use the Fire* methods to produce detailed messages before redirecting the row to the error output, but this sort of thing is not available through the standard components.

Do I really have to create a separate "add useful information to the error output" component, and use it on each error output?

Sorry for the attitude, but just when I think I'm winning, SSIS brings me back down to earth!

If you want to identify which component produced an error then simply hook a derived column component up to the error path that adds the name of the component producing the error to the data path. Thats that one taken care of!

"Do I really have to create a separate "add useful information to the error output" component, and use it on each error output?"

Whats the problem with doing that? Granted you could argue that this information should be included anyway but the rationale for it NOT being there is that it could potentially take up A LOT of memory - a rationale that I agree with. hence you have the opportunity to do it yourself.

Note that if youre using a UNION ALL to collate all of your error rows into one place then you only need to do this once.

The main problem is that I don't know how!

The second problem is that there are about 50 or so places I'd have to add one of these components.

In particular, how can a downstream component learn about the component next-upstream? I also don't know how I'd "do it only once" downstream of the Union All.

|||

I've implemented a Derived Column transform for the first few of my error outputs, and it works well enough.

My next issue is that I have two custom components that are very heavily used. They produce good error messages through the Fire* methods. I now would like to take the messages they produce and place them into my new ErrorMessage column. I added a dummy Derived Column transform to the start of the chain of transforms in order to make the ErrorMesage column available with the correct data type and size throughout the transform chain.

The problem is that both of my components do nonstandard things with their collection of input columns, so I can't just add ErrorMessage as an input column. I know how to get the buffer index for an input column and how to use it to get values from the buffer for the column, and how to set them into the buffer.

My question is: can I get a buffer index for a column not in my input columns collection and use that index to set the value of that column? I see that there's a Virtual Input and Virtual Input Column Collection, but I haven't seen examples of how to use it.

This does sound like a hack, and I promise to fix it once I get the leisure to write a UI for these components so they don't have to do strange things with their input column collections.

Thanks.|||

I'm not understanding why. If you push all the error outputs into a UNION ALL then you just need to add the code that I linked to above in a single component downstream of the UNION ALL. Unless I'm misunderstanding.

It can't but I don't know why you'd want to.

Spot on. Yes, you can do that. To be honest, the virtual input is what you see in the designer. The inputitself contais the columns that are selected at design-time. hence the columns in the input are a subset of teh volumns in the virtual input.

This code will return the virtual input and let you process the columns

Code Snippet

IDtsVirtualInput90 vInput = ComponentMetadata.InputCollection[0].GetVirtualInput();

foreach (IDtsVirtualInputColumn90 in vInput)

{

///blah blah blah

}

[that's done from memory so don't hang me if it doesn't work Smile ]

By the way, I will be publishing some code, via my blog and codeplex, in the next couple of days that does exactly this i.e. process data based on the virtual input. Keep a look out for that. Addrss is below.

Best Practice: Procedures: (Insert And Update) OR JUST (Save)

I have a Product Table.

And now I have to create its Stored Procedures.

I am asking the best practice regarding the methods Insert And Update.

There are two options.

1. Create separate 2 procedures like InsertProduct and UpdateProduct.

2. Create just 1 procedure like ModifyProduct. In which programmatically check that either the record is present or not. If present then update and if not then insert. Just like Imar has done in his articlehttp://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=419

Can any one explain the better one.

Waiting for helpful replies.

http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=419

a

There's no "best practice" for this one. Imar presumably likes his "Save" approach because whether you are adding a new record or amending an existing one, generally software applications ask you to click the Save button - so he likes to make his programming logic analogous.

Personally, I prefer theKISS principal, and create 2 separate procedures. It's clear from the interface which one to call as a result of user action. I also see the decision as to whether to Insert or Update as being a business logic decision, and I'm uncomfortable about putting business logic in a stored procedure. The reason for this is that the business logic may not be transferable to another database platform.

|||

I do not understand your last point regardgin Business Logic.

I understand that it should be better in your opinion to create 2 separate procedures.

But what about Business Logic Methods.

|||

zeeshanuddinkhan@.hotmail.com:

I do not understand your last point regardgin Business Logic.

Well, I suppose it depends on how you define "Business Logic". And this illustrates one of the problems with layering an application. The reason why there are so many books and theories on architecture is because there is no "right" way to do it, and definitions of what belongs in which layer are different. Some things so obviously belong in certain layers, but other things might or might not - depending on what you are used to, how you think, what you are told to do by your team leader etc. There is for example, a huge debate about whether stored procedures are a bad thing altogether, because they can be viewed as placing business logic in a database and not in the BLL.

It also depends on how atomic (how much you like to break functionality down into discrete parts - methods, classes, procedures etc) you want your application. Imar would no doubt suggest that the action of the user defines that a Save() method be called, and that while the Save() method can include two alternative actions (Insert or Update), both lead to a row being saved to the database, so it's essentially the same action. The procedure decides whether an existing row is updated or a new one created. I see the difference between Insert and Update as being too different to be combined into one method. Consequently, I break the procedures apart into separate atomic constructs. I view the difference between the 2 as a business logic thing - because I can - and something in my gut tell me it is.

That's purely my view and is neither right or wrong. Others may not agree, and they will no doubt have valid justification for their view. It's right for me but wrong for Imar. And that's why I said at the beginning that there is no Best Practice for Insert or Update v Save. It's purely down to your personal preference. Imar's solution has a certain appeal, in that it contains a certain "cleverness". Some people like that. Nothing wrong with that at all.

Quite often the difference between two alternatives is purely philosophical, and has nothing to do with performance, maintainability or re-useability, which are the three items that Best Practice should be concerned with.

[Edit]

Just re-read my first response and having rambled on above, I see I may have missed your point. If you were asking about transferable business logic, it may be that you have to move the application to a different database system which doesn't support stored procedures, but may support basic INSERT, UPDATE, SELECT and DELETE saved queries. In this case, it wouldn't be too difficult to copy and paste the SQL form each part of the proc, but if you make procs do too much in terms of massaging data, or deciding on a course of action, you will create a load more work in your migration.

You are also perfectly free to ignore this on the basis that "it will never happen". Only you know best.

Best eqivalent to a Data Transform Task

Hi
What is the best TSql to a Data Transform Task that just copies data from
one db to another.
Reason for asking, is that I have a DTS package that just does a number of
copies of tables from one database to another (the databases are on
different servers) and occasionally one of these task fails. When it fails,
it doesnt report any errors and the whole execution of the package succeds
without any errors. It doesn't happen very often, so that also makes is
quite difficult to find out why.
As an atempt to find the reason, I'd make these copies/transforms as TSql
jobs, so I'd like to know what would be the best way to do it with Tsql?
Have any of you any good suggestions to this?
Regards
Steen
It could simply be, something like this:
INSERT INTO DB1.dbo.Table1
(Col1, Col2, Col3, Col4, Col5)
SELECT
Col1, Col2, Col3, Col4, Col5
FROM DB2.dbo.Table1

|||Hi Vyas
Thanks for your input - I was thinking about something like myself, but just
wanted to see if there was a smarter way I didn't knew about.
I seems to have some problems getting this so work in a DTS package though.
I've created a package with a source and destination which are 2 different
servers. I've then made a task that executes a sql statement that should
copy the data from one table in 'server1' to another table in 'server2'.
The code is :
INSERT INTO DATABASE2.dbo.Table2
(Col1, Col2, Col3)
SELECT
Col1, Col2, Col3
FROM [Server1].Database1.dbo.Table1
When I execute this in a Query analyser it works fine, but when I set it
into the data transform task, and parse the query, it gives me an "Invalid
object name DATABASE2.dbo.Table2" error.
I'm building this package on server2, so to some degree I understand that it
can't find/see server1, but why does it then work in a QA.
I've then in the same Transform task tried to do a sp_addlinkedserver -
USE master
GO
EXEC sp_addlinkedserver
'Server2',
N'SQL Server'
GO
When I try this in QA, it tells me that the server alreday exist, and when I
add it to my SQL statement in the Transform Task, it gives we a syntax error
around the "GO" statements.
It might just be me that are doing something stupid, but I just can't see
why it doesn't work. It also puzzles me a little bit why it react diffently
in QA and in the Transform Task, but most likely there are a good reason for
that.

I have played a little bit with the code, and it now seems like I've got it
working without the Linkedserver option.
I then just have one more simple question - Is there an easy or simple way
to get the INSERT INTO command to take all the colunms in the table without

I've then in the same Transform task tried to do a sp_addlinkedserver -
USE master
GO
EXEC sp_addlinkedserver
'Server2',
N'SQL Server'
GO
When I try this in QA, it tells me that the server alreday exist, and when I
add it to my SQL statement in the Transform Task, it gives we a syntax error
around the "GO" statements.
It might just be me that are doing something stupid, but I just can't see
why it doesn't work. It also puzzles me a little bit why it react diffently
in QA and in the Transform Task, but most likely there are a good reason for
that.

I have played a little bit with the code, and it now seems like I've got it
working without the Linkedserver option.
I then just have one more simple question - Is there an easy or simple way
to get the INSERT INTO command to take all the colunms in the table without
having to type them all in? Some of the tables I'm working on has quite a
number of columns so I'm already tired just thinking of having to type all
these in by hand.
