Special Error Handle In A Dataflow Transformation Tasks
Jan 22, 2008
Hello,
How would you do a log in a massive rows loading, I'm having problems because every row error(because of casting, format, lookup) in a transformation task is redirected to a text file as a log, this is ok when only exist one error by row, but in the case when I have two errors in the same row detected by diferents transformation tasks only the first one is reported to the text file, I have to wait to the second information load, after I correct the first error, to find the second one, I need to validate as many errors exists by row in the same load...
which component or which strategy can I use in a SSIS Packge to achieve this?
thanks

Thanks in advance in reading this thread.
I have developed a big SSIS package to extract data from flat-files ( + 200 Dataflows ).
The situation is the following, inside de SSIS package, there are a lot of validations before extracting & loading the flat-files, i'm running this validations in paralell, so that when a file arrives, it enters the "validation process" and start extracting the file.
When i run the SSIS package from BIDS it works the way i have concepted it... but when i run the ssis in the server, the tables that are loaded through the process are only "available" when the SSIS PACKAGE ends, it is imperative that trough the process, when a table receives new data, it becomes ready, and don't just be available when the SSIS package finishes...
I have attached the an lousing .jpeg.
It is importart for the tables to be available, so the stored procedures(OUTSIDE SSIS PACKAGE) that are dependent of some tables, start working before the SSIS package Ends.
Thanks in Advance.

Hi,
Is it possible to change the Dataflow tasks properties with VB coding? I've managed to change the properties of the control Flow tasks with VB code! as I wan to create a generic dataflow that will change everytime I run it.
Cheers

I've create a package that currently uses 5 DataFlow tasks connected in series to get data from 5 different files and place that information into 5 different temp tables. Each Dataflow task contains only a OLE Source, a row count and a OLE destination. My question is - Is it normal practise to keep each of these separate, or should I put them all into a single DataFlow? The package should only continue if all five dataflow task complete successfully.

I may have misunderstood how Lookupu works because it's not doing what I want.
From the OLTP datasource I have a long list of revenue items (from a SQL server database). I want to assign these to specific accounts as they are transferred into our accounting system. I have another table with a list of words to search for and which account they belong to.
For example if the OLTP source might be
Description - Amount
"Sales of cars"- "$20,000"
"Motorcycle sales" - "$15,000"
"Bike rentals" - "$2,000"
The account lookup table is like
Wordsearch - Account
"sale" - "ACCT_SAL"
"rental" - "ACCT_RENT"
So by looking up whether "wordsearch" is found in "desription" I should get an output of
ACCT_SAL - $20,000
ACCT_SAL - $15,000
ACCT_RENT - $2,000
Back in DTS I did this with an array and "If Instr" using VBScript in the Data Transformation Task. I'm sure there must be something in SSIS to do this - it should be something like a Fuzzy Lookup ?, but I'm drifting toward Script Component. Anyone got any ideas for SSIS

Hi,
I am creating dataflow tasj using following
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Pipeline
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
These refer to Microsoft.SqlServer.DTSPipelineWrap.dll and Microsoft.SQLServer.DTSRuntimeWrap.dll. While these assemblies were already there in my dev machine I don't find these files in production enviornment for SQL server 2005. I am refering these assemblies from following path in my local machine : C:Program FilesMicrosoft SQL Server90SDKAssemblies.
How to install these assemblies in prod env, offcource one option is to copy it and then put it in GAC thru script . Why does not it gets installed while installation of SQL server 2005. Are these assemly dependent on SP1 ?
Thanks

I've created a custom data flow tranformation and it isn't showing up in the Tool Box Items to be added under the Data Flow Items tab (right click on tool box, 'Choose Items...', then clicked Data Flow Items).
I have done the following:
signed the assembly,
added to GAC,
copied the dll to C:Program FilesMicrosoft SQL Server90DTSPipelineComponents.
It worked previously when I was just starting out, however now I cannot see it. What would cause it to not show up? Everything compiles fine. How would I determine how to fix it so that it shows up?

I'm not exactly sure how to ask this question ... but here goes!!
I want to get an idea of how SSIS actually executes transformation tasks.
Do transformation tasks (eg a lookup) complie down to managed code or are the executed as SQL commands in a SQL server database?
Thanks.

Hello all -
Working on DTS packages we used to have two different ways of exporting data to spreadsheet... We could do it by a single transformation task or either writing an ActiveX script, after running a procedure.
I am able to cover the first way already, while dealing with SSIS... But, I wonder if it is worth to research on how I would write a vb.net code to load data into a spreadsheet (considering we are advised to try vb.net instead of ActiveX while working on these new packages).
It is always a huge discussion to know what is the best way of doing something so my point here is to hear some of you and decide if I just keep exporting data by doing transformation tasks or if I will ever go trying to deploy a vb.net code to do that... What is the best on performance, etc...?
Thanks in advance for all your help as always.

Hi
I have migrated a DTS that had some activeX transformation tasks within data pump flow tasks.
Those parts were migrated as "DTS 2000 tasks" .. so activeX transformation tasks aren't possible in SSIS ?
I know ActiveX script tasks are but for transformations ?
1. IF i leave these Encapsulated DTS 2000 tasks in the migrated SSIS package, will it run independently of the original
DTS or does it need the old DTS running to "call" that part from ? (I hope im making sense here)
is it possible to load this functionality internally into the new SSIS ?
2.
How could I (if i can't do ActiveX transformation tasks) achieve this is SSIS ?
can I achive this using the script tasks in SSIS ?

Hi guys,
I need to use a SQL statement to lookup a value from a SQL server database table that relates to a column in my dataflow.
Imagine a SQL database table called 'cars' with values of
Year | Description
2005 Ferrari 355
2005 Ferrari 355 Spider
2006 Ferrari 355 F1
In my data flow I have Year and Model eg.
Year | Model
2005 355
2006 355
In my SQL statement I want to select from the 'cars' table where the years match exactly but the 'description' is like the 'Model'. eg. %355%
So essentially, how do I construct the 'like' clause in the select statement to reference the 'Model' column please?
thanks for your help,
Chris

Hi there,
This seems a bug to me. Or does anyone has a logical explanation that escapes me?
When in SSIS Designer Version 9.00.1399.00 I add output columns (numeric 4,0 ) to a scriptcomponent and fill them with valid numeric data in thescript I get a database error 'invalid number' when I use these columns in an OLE db Command-transformation . This errormessage disappears when I replaces those columns by a dataconversion to the datatype they originally have.
Derived Column Name Derived Column Expression
STATUS_DEF Replace 'STATUS_DEF' (DT_NUMERIC,4,0)STATUS_DEF
Maybethis info is usefull for somebody else who can't figure out wathever he's doing wrong.

Dear All!
My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database.
Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any

I am writing a custom dataflow transformation component and I need to get the name of the preceeding component.
I have been trying to find a way to get a reference to the Package object, MainPipe object or IDTSPath90 object (connecting to the IDTSInput90 of my component) from my component because I think from there I can get to the information I want.
Does anyone have any suggestions?

Hi
I'm using service broker and keep getting errors in the log even though everythig is working as expected
SQL Server 2005
Two databases
Two end points - 1 in each database
Two stored procedures:
SP1 is activated when a message enters the sending queue. it insert a new row in a table
SP2 is activated when a response is sent from the receiving queue. it cleans up the sending queue.
I have a table with an update trigger
In that trigger, if the updted row meets a certain condition a dialogue is created and a message is sent to the sending queue.
I know that SP1 and SP2 are behaving properly because i get the expected result.
Sp1 is inserteding the expected data in the table
SP2 is cleaning up the sending queue.
In the Sql Server log however i'm getting errors on both of the stored procs.
error #1
The activated proc <SP 1 Name> running on queue Applications.dbo.ffreceiverQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
error #2
The activated proc <SP 2 Name> running on queue ADAPT_APP.dbo.ffsenderQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
I would appreceiate anybody's help into why i'm getting this. have i set up the stored procs in correctly?
i can provide code of the stored procs if that helps.
thanks.

Dear Friends,
I need to execute a SQL query, inside a dataflow (not in controlFlow) and need the records returned to continue the dataflow... In my case I cant use lookup and OLE DB COmmand and nothing else...
I need to execute a query and need the records for dataflow... with OLE DB command I cant see the fields returned... :-(
How can I do it? Using a script? Can I use a Script Component? That receive 2 parameters for input and give me the fields returned from query as output?
Thanks!!

This error seem to be very silly.did anyone come across this error.
I have been transferring data from textfile to a table using oledb destination.
The number of records in the text file are 2,091,650
Its was running just fine couple of days ago when the incoming data was little small then this...(arround 300,000).Now it seem to have a problem.
Here is the flow
1.File System task ->I copy the file to different location
2.Execute sql task->truncate tables
3.DataFlow task->I check for only the error files in this data flow.and all valid rows i transfer to a different text file.
4.Dataflow->filesource i connect to new text file created earlier.Here i convert fields to repective datatype and i insert if new or update record.
I dont know whats going on...
When i run my package it runs through the first three perfectly fine.When it comes to fourth step it sits there.....it dosent go to the tasks within this dataflow at all...and begining i have flat files source...
What could be the reason...
when i look at progress tab...i was able to look at the progress of other tasks but when it comes to this task it shows start>>>>>time and it sits there...

HI, I have a lookup that find a specific row. If that row does not exist, I need to create a new one. If it exists, I need to raise an error and trap it with the "on_error" event of the dataflow in order to log it. Is there a way to raise an error and specify the error message from the dataflow? I was thinking using the conditional split and verify if the value returned from the lookup (by set the error config to ignore the error) is not or not. But how can I raise an error when the value is not null?
Thank you,
Ccote

Hi,
I have a SSIS package which is scheduled to run via SQL Agent. I have a data flow task within the SSIS Package which has a single source adapter and single destination adapter & lookup transformations.
The # of engine threads for the task is 5 (default). The max concurrent executables on the package is 20. The packge contains a whole lot of execute sql tasks etc.
The package after few (3-4) successful runs started to give following error for the data flow:
"The Data Flow task engine failed at startup because it cannot create one or more required threads"
This could be seen from the log files.
OR
"Data Flow task failed to create a required thread and cannot begin running. The usually occurs when there is an out-of-memory state."
Even if concurrent exectuables are set to -1 it is same.
Now the Package keeps on failing. What is the cause of this problem. I have not run, but I am sure once run through BIDS it would work fine.
Any hints on the same? This has put us in a trouble spot.
Server Config:
4 - WAY, 16 GB RAM, enough disk!
Thanks,
Gaurav

Is it possible to catch and error and then keep the process going in a stored procedure?
So if an update encounters a primary key violation on a row, is it possible to skip that row and keep the process going?

Hi! I have some try .. catch block trying to insert some data into database. During its action duplicate key row insert error could raise, for example. The question is how could I know distinguish it from other sql errors? Object ex (Catch ex As Exception) has only message property '{"Cannot insert duplicate key row in object 'dbo.Group_Courses' with unique index 'IX_Group_Courses'.The statement has been terminated."}' and type System.Data.SqlClient.SqlException. Knowing the type of error is not enough, because there are different SqlExceptions. Even the message is not unique for this error, because now i deal with 'dbo.Group_Courses' and then it could be other table. Is there something that unique identifies each error? For example error code. If it exists, where could I get it?
Thanks in advance!

Hi,
I would like to handle a sql error in t-sql and return a certain value in case error occurs. For example if I would like to add a record I want to return a certain identity value or maybe a status of transaction (0 for incomplete, 1 for succesfull trans).
If error occurs in sql I cannot return any values back to asp.net because of What I am doing at the moment is catching an error in asp.net and then displaying an error message. Is there a way to return only a return value to asp.net and somehow handle the error in t-sql?
Thanks

Hi,
In terms of data flow tasks, when say we load text files into databases.
Is it possible to have it in a way so that if a certain record (line in the text file) fails to load due to watever reason, it gets written to another table, but the rest of the records still get loaded?
I try to do so and end up with the whole data flow task failing and it stalls at the record that had the error and doesn't seem to continue forward.
I just used the red arrow (on failure) and put that to another SQL destination object. But yeah that didnt work.
If someone has a better way of doing so, would be awesome if you can share that.
Cheers

Hello, to give you a background on where I'm coming from:
I have an SSIS Package with a global String variable that has an sql statement. so it says something like: "Select * from MyTable "
I than have a SQL Script Task where I append a WHERE Statement to my string.
Than in the Dataflow Task when I select the source database, I run command from Variable.
When I run the package I get an error that my string is too long. My string is about 750 characters that I'm trying to pass through.
Is there some limitation to this?
I have ran the raw SQL Command in the SQL manager and it runs fine. I have built a million of these packages, just not one with such a large string.
If it is the case that it is just too long, is there a work around to that?
Thanks,
Rusty.

I have an SSIS Packaget that worked a month ago and when I ran it today it didn't work. It's failing in the ScriptComponent in a DataFlow that I created as a Destination. The only thing the script does is record any value for a particular column and on the PostExecute method, writes the last instance of that column to a user variable in the Package. Here's the code. There is a string variable that I use to hold the column's value for each row received.
Public Class ScriptMain
Inherits UserComponent
Dim s_remit_addr As String
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Me.s_remit_addr = Row.remitaddr.ToString()
End Sub
Public Overrides Sub PostExecute()
Dim variables As Variables
Variables.gsremitaddr = Me.s_remit_addr
MyBase.PostExecute()
End Sub
It will always bomb in PostExecute with the error that the variable User::gs_remit_addr is not the same type as the variable I'm using (s_remit_addr); HOWEVER, the user variable is of type String and it worked a month ago. Does anyone have any idea how I can fix it?
