Incorrect Truncation Warning In Data Flow
Feb 5, 2008
All,
I'm getting a strange truncation warning in a data flow, similar to what is posted here:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2629939&SiteID=1
In my case, I have a column in a pipeline that is DT_STR with a length of 20. I'm trying to insert data from the data flow into a table (via an OLEDB destination) in which the destination column is varchar(50). When I review the metadata throughout the data flow, everything looks correct. However, I get a truncation warning stating that data loss might occur when inserting data into the string column of length 20 from a source column of length 50. Thus, it looks like the data flow is swapping the metadata for the source and destination columns when validating the data flow (and thus, producting the warning).
This is a pretty complex data flow, so I'd rather not have to rebuild it. And changing the metadata of the source column to be DT_STR with a length of 50 is going to wreak minor havoc in the data flow (as lots of things use that column).
Has anyone seen anything similar to this? The post referenced above deals with a package that is constructed programmatically, but the package I'm working with was created the old fashioned way...
Any help would be appreciated.

I keep getting a waring:
[Production IDW [1]] Warning: Truncation may occur due to retrieving data from database column "Industry" with a length of 16 to data flow column "Industry" with a length of 8.
When I look at the industry lookup table the column size is 50. But the data flow metatdata is saying the oclumn is 8. How can I change the data flow column? When I try to edit it and click on metadata it is uneditable. The field it is matching to is 50 and the field it is coming from is 16.

Hello,
I'm having a problem with one of my packages due to a truncation warning that I can't get rid of. It's not the end of the world, because the package still works. It's just extremely frustrating.
The problem arises in a derived column item in a data flow task. There is a postcode field in the data flow which has space for 20 characters. I create a derived column from this which simply removes any spaces:
Derived Column Name: Postcode
Derived Column: Replace 'Postcode'
Expression: REPLACE(" ",Postcode,"")
Data Type: string [DT_STR]
Length: 20
Code Page: 1252 (ANSI - Latin I)
However when I use this expression, or anything else which uses the replace function, I end up with the warning message:
Warning 1 Validation warning. Create Staging Tables: Derived Column [20555]: The result string for expression "REPLACE(" ",Postcode,"")" may be truncated if it exceeds the maximum length of 4000 characters. The expression could have a result value that exceeds the maximum size of a DT_WSTR.
I have tried everything I can think of to get rid of the warning. Is there some way I can use the replace function, but not have the system convinced that I'm about to go over the maximum size limit?
Many thanks

I built my package on my development machine with a config file at a given location. Let's say:-
C:DevelopmentdtsConfig.xml
Then I shipped my package to the Production machine and ran my package (in a .bat file) as follows:-
DTExec /FILE "C:ProductionPackage.dtsx" /CONFIGFILE "C:ProductiondtsConfig.xml"
But I get the following output:-
Microsoft (R) SQL Server Execute Package Utility

Source: Package
Description: The configuration file name "C:DevelopmentdtsConfig.xml" is not valid. Check the configuration file name.
End Warning
...
But then it goes on to read values from my Production config file.
How can I stop the annoying warning about my Development config file-path (which doesn't exist on the Production machine)
Thanks

Hi,
I have a data file that has numeric data that looks like:
1.123456
And this column is defined as a DT_NUMERIC(18.6) in the flat file conn mgr.
As an experiment, I changed the destination column to a NUMERIC(18,0) - hoping that this would throw a truncation error at the flat file task level (where I have Truncation on all columns set to "fail component").
Not a peep. It loaded the data into the table, chopping off the 6 digits after the decimal point.
You would THINK that this would cause an error, but no. Why is this? The flat file task complains about all kinds of things, but this is such a gross error, you would think it would catch it!
Thanks

Hi, All,
I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesn€™t have anything for mapping parameter.
Thanks in Advance

I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Thanks,
Steve

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
Thanks

Hi everyone,
Primary platform is 64 bit cluster.
How to move information allocated in SSIS variables from Data Flow to Control Flow layers??
We've got a SSIS package which load a value into a variable inside a Data Flow. Going back to Control Flow how could we retrive that value again????
Thanks in advance and regards,

I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.

A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.
The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.
A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:
EXEC sp_addlinkedserver
@server = 'server_name',
@srvproduct = '',
@provider = 'MSDASQL',
@datasrc = 'odbc_dsn_name'
Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.
Any assistance would be appreciated.

Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)
http://i248.photobucket.com/albums/gg168/boston_sql92/1.jpg

http://i248.photobucket.com/albums/gg168/boston_sql92/5.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/6.jpg
The same package works fine against a similar test table with 150k rows.
http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.

Hi,
I am trying to execute one huge select statement from my application using ODBC, but I am getting this error:
[Microsoft][ODBC SQL Server Driver]String data, right truncation.
the select statement is bigger than 2000 characters, but I don't have any long string column, just strings and numbers. How can I work around this?
Is there any max size? Because if I use less than 1000 characters, it works fine.
I am using Centura/SqlWindows, Native Sql Server ODBC and SqlServer 2005. unfortunately, I can not use Ole from my application.
cheers,

Hello, I am trying to store pictures in an Image data type column of my MsSQL table from PHP, or even SQL Query Analyzer for that matter. In PHP I use the bin2hex() function to get the HEX equivilent of the picture, I'm sure everyone knows that when you convert a Binary file to HEX, the file size is doubled. When I try to insert the HEX file into my table with a query like:
INSERT INTO PicTable (fileType, fileData) VALUES ('jpg', 0x47494638396164014100f70000000000ffffff2f2f2fe800020c0c0ce....)
MsSQL will store EXACTLY HALF of the file. The byte count of the stored HEX data and original Binary data is exactly the same, so when I try to extract the file and display it, in a browser window for instance, I can see exactly half of the image. I have tried everything I can think of to fix this, but I am at a loss. Does anyone know of anything that would cause this strange behavior. I have no problems at all doing this with MySQL's BLOB data type. Thanks in advance for any help.

Hi,
I am having issues importing data from a text file into a SQL database table using the import wizard in SQL Server 2005.
The text file contains polygon coordinates and a polygon name and looks like this:
"42.2342342,-121.1351398|42.3467984752,-122.2349234, ... ..., 42.1897498174,-122.131983","Polygon Name 1"
"42.2342342,-121.1351398|42.3467984752,-122.2349234, ... ..., 42.1897498174,-122.131983","Polygon Name 2"
and the SQL table looks like this:
polycoordinates varbinary(MAX)
polygonname varchar(50)
The length of the longest polygon coordinates record is about 115,000 characters. I believe the varbinary(MAX) type should hold that data, but SQL throws a truncation error every time I try to import the data.
Any suggestions?
Thanks,
Jay

I'm reading data from a flat file source. If some data gets truncated, i have the option of 'ignoring', 'redirecting' or 'fail component'.
What i'd like to do is, to allow the data to be truncated, but i'd also like to write a log entry so that i can know that a particular rows data has been truncated.
I've tried 'redirecting' the row to a script component (as transformation), but i don't know how to determine if the error is truncation or not, not only that, i can't redirect the row back to the 'original' flow, which is a derived field column.
Any ideas on how to do ?
Cheers.

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.

hi
"Bulk insert data conversion error (truncation) for row 1, column 1 (id)."
when you get the error above or similar in sql server 2000 does it continue inserting the data by truncating it or does it stop beacause looking at the data that i have got it seems to continue inserting the data but just truncates the colunm. i have tried it several time its seeems to be consistent.
I have data that has white spaces after the actual data e.g. '00093 ' hence i am happy aslong as i can be sure that it does always continue as i will be loading alot of data using a similar process.
hence my question is that will it load all the data all the time and just truncate it to fit the column size?

Good morning, all,
I am working on importing an Excel workbook, saved as multiple CSV flat files, that has both group level data and related detail row on the same sheet. I have been able to import the group data into a table. As part of the Data Flow task, I want to be able to save the key value for the group, which I will use when I insert the detail rows.
My Data Flow has the following components: The flat file with the data, which goes to a derived column transformation to strip out extraneous dashes, which leads to the OLEDB Destination component.
I want to save the value as a package level variable, so that I can reference it in another dataflow.
Is this possible, and if so, at what point do I save the value?
Thanks,
Kathryn

Is there a switch I can use to force a bulk insert and if data is truncated, I'm good with that. The truncated data, in this case, is not data I can use anyway if it is long enough to be truncated.
I need to keep the field at VARCHAR(23) and if I expand it, I won't be able to join on it after the file load completes. I'd like the data to be inserted (truncated if need be) and then I'll deal with the records that are truncated after I load the file.

Hello,
I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".
To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.
The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).
I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.
Why the process could be so long during this phase?
There is a way to optimised my package to avoid that?
Any idea is welcome.
Thanks.

Hi All,
I want to export data from SQL Server2005 to an Excel spreadsheet thru "Data Flow Task". I am using OLE DB for SQL Server for the source connection and a Connection To Excel as my destination source. The Excel spreadsheet (2003) exists and has the first row with column names. I don't have any warnings before trying to execute.
The SQL datable fileds are
i) ID - Int
ii) RefID
iii) txtRemarks - nvarchar(MAX)
iv) ddlWaterLevel - nvarchar(50)
While executing the tasks, I got the error
Error: 0xC0202025 at Data Flow Task, Excel Destination [427]: Cannot create an OLE DB accessor. Verify that the column metadata is valid.
Error: 0xC004701A at Data Flow Task, DTS.Pipeline: component "Excel Destination" (427) failed the pre-execute phase and returned error code 0xC0202025.
After analysing I found in the DataFlow --> Excel destination --> Advanced Editor for Excel Destination, the default data type for txtRemarks shows as "Unicode string [DT_WSTR]". But this is supposed to be "Unicode text stream [DT_NTEXT]". Even if I change the data type in the design time, It doesn't accept.
Please do help me out.
thanks

I am getting the following error running a data flow that splits the input data into multiple streams and writes the results of each stream to the same destination table:
"This operation conflicts with another pending operation on this transaction. The operation failed."
The flow starts with a single source table with one row per student and multiple scores for that student. It does a few lookups and then splits the stream (using Multicast) in several layers, ultimately generating 25 destinations (one for each score to be recorded), all going to the same table (like a fact table). This all is running under a transaction at the package level, which is distributed to a separate machine.
Apparently, I cannot have all of these streams inserting data into the same table at one time. I don't understand why not. In an OLTP system, many transactions are inserting records into the same table at once. Why can't I do that within the same transaction?
I suppose I can use a UnionAll to join them back together before writing to a single destination, but that seems like an unnecessary waste and clutters the flow. Can anyone offer a different solution or a reason why this fails in the first place?
Thanks in advance.
