SSIS Data Flow Task Fails To Load All Text From Flat File
Jan 2, 2007
Hi Guys,
I
have a flat file which is loaded into the database on a daily basis.
The file contains rows of strings which I load into a table,
specifically to a column of length 8000.
The string has a length of 690, but the format is like 'xxxxxx xx xx..'
and so on, where 'xxxx' represents data. So there are spaces, etc present in the middle.
Previously
I used SQL 2000 DTS to load the files in, and it was just a Column
Transformation with the Col001 from the text file loading straight to
my table column. After the load, if I select len(col) it gives me 750
for all rows.
Once I started to migrate this to SSIS, I
allocated the Control Flow Task and specified the flat file source and
the oledb destination, and gave the output column a type of String and
output column width of 8000. But when I run the data flow task it
copies only 181 or 231 characters out of the 750 required.
I feel it stops where it finds the SPACES and skips the rest.
I
specified row delimiters or CR, and LF. I checked the file under
UltraEdit and there were no special characters in the file that would
cause the problem.
Any suggestions how I can get it to load the full data?
We have created SSIS package to load a text file into a table. Source system shares 10 text files and recently they stopped generating data for one of the text file (comping empty), after few months they will start generating the data for the empty file batch processing.
The Issue here is Data Flow task is getting failed while loading empty text file into table. How to handle this empty file load issue in SSIS package.
I have a Data Flow Task within a ForEach loop container. The source of the flow is ADO.NET connection and the destination is a Flat File Connection. I loop through a collection of strings in the ForEach loop. Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:
[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process. [Flat File Destination [38]] Error: Cannot open the datafile "Example.csv". [SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.
I know what's happening but I don't know how to fix it. The first time through the ForEach loop, the destination file is updated. The second time is when this error pops up. I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.
How do i use the foreach loop container and pass each file found according to a specified pattern to a Flat File Source in a Data Flow Task Object so i can operate on each file found in the foreach loop object instead of having to specify a static file name
I'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination).
With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table.
I used two different flat file sources and got the following:
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
And i want to use SSIS package dynamically load data from database into three separate flat file, each table into each file.
I know i got to use for each loop task ADO.Net schema row set enumerator, with OLEDB connection manager, select table name or view name variable from access mode list, but the problem comes, as table name is dynamic then flat file connection is also dynamic, i am using visual studio 2013...
I'm working on SSIS to load the data from flat file to sql server, I'm getting date in below format, but in sql server I have given data type datetime. how to convert below format to 16-01-15 12.05.19.1234 AM.
I seem somehow stuck in some Script Task problems in SSIS on a x64-environment which has SP2 installed already.
If I'm running the package in 32-bit mode, I'm continuously getting the following error "Warning: Precompiled script failed to load. Attempting to recompile. For more information, see the Microsoft Knowledge Base article, KB931846 (http://go.microsoft.com/fwlink/?LinkId=81885)."
on one of the package's scripts -- the given links advises to install SP2... what a useless hint.
And if I switch the project to run in Run64BitRuntime=True , another script tasks complains "ScriptTask_78888010d24c477ea7c8d69f4f5568a5 is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
-- whatever that might mean...
Maybe I should add that the packages were running in 32-bit mode for the last 12 months now. Without any problems like that.
Those effects are occuring since we put SP2 onto the server...
Any comments on this topic? Similar experiences? Maybe yet some solutions too?
Since applying July 2007 Microsoft patches it was noted that we were not able to open the editor for the Script Task component in an SSIS package. We received an error dialog with text similar to 'Engine failed with unknown error. (Microsoft.VisualBasic.Vsa.Dt).' All other solutions provided in the forum did not resolve our issue. It was noted somewhere else that the OLE32.dll seemed to have been affected. We reregistered this file using the command 'regsvr32.exe ole32.dll' and suddenly we were able to get into the editor. I don't know why this fixed the issue, but it did for us in our environment. Good luck!
any suggestions on dealing with a flat file in the format below. I only want to process the data columns in the middle of the file and want to ignore all other rows. This was a very simple task in DTS with a small amount of VBScript in the transformation but it doesn't seem as straightforward in SSIS. thanks
I have a table that holds in each record an image (varbinary(max) actually), a text reference for the image and a MIME type for the image. I need to read this table and for each record that has been created since the last run, I need to create a file with the image as the content, the mime type as the file extension and the text reference as the file name. There will be one file created per record found by the data flow source.
I was assuming that I could use the flat file destination and manipulate the file naming using the contents of each record in the flow but am completely stumped on how to achieve this.
Hello Experts, I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle). PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not.. What should go here ? ->Under Class A
All, I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!
I am having difficulties loading data from a flat file to a SQL Database. I am able to load some data but the rest gets kicked out for the following reasons:
1 – The field is varchar 50 and I would like to convert it to a date field 2 – The field contain periods (.) (Only 1 period in each row) 3 – The field contain blanks (NULLS)
How do I create a derived column that will bypass blanks (Nulls) and remove periods (.) in each row then convert column to a date field in SSIS? Looking for steps to create a derived date column using SSIS (derived task); convert it to a date column (09-19-2015); use functions to redirect the nulls and possibly remove the period (.)?
[b][u]Sample Data[/u][/b] Column 3 (Varchar 50) Need to convert to date; remove periods, and bypass nulls(blanks) Blank . Blank . Blank Blank . 01-19-2015 01-19-2015 Blank . Blanlk . Blank 01-19-2015 . Blank .
I was working all day making changes to my 3MB package. I was adding a large number of transforms that were copied-and-pasted from elsewhere in the same data flow task.
All was going well. I even took the time to have SSIS lay out the task again (1/2 hour). Suddenly I started receiving some strange errors:
After the layout, I noticed two stray components 'way off in the upper right corner. I found that one of them had a duplicate name to a component which had been added hours ago. Even after deleting it, I got "duplicate name" errors.
I copied three components in one selection, and when I tried to paste them, got the error "can't initialize component on paste". I tried them one at a time, but got the same error.
I got errors about COM failures due to marshalling to another thread I then exited Visual Studio and started it again. To my great surprise, the data flow task I was working on was still there, but was completely empty.
Comparing what I'm left with to my last version in source control, I find that the entire pipeline element is missing from the DTS: ObjectData element!
I'm developing a real love/hate relationship with SSIS. It varies from one day to the next. Guess what kind of day this is!
I have developed a SQL Server 2005 Integration Services (SSIS) package that includes a Script Task on a 32-bit machine. The PrecompileScriptIntoBinaryCode property is set to True. After I build the package, the .dtsx file includes a <BinaryItem> element for that Task. Package runs fine on the dev machine, both in BIDS and as SQL Server Agent job. When I deploy the package to a 64-bit server, it runs fine when I execute the package ad hoc from SQL Server Management Studio. However, when I schedule the package for execution as a SQL Server Agent job, the package fails with the message: "the script files failed to load." I have reviewed posts on this error from late 2005, but the solutions don't work in this case. Specifically: 1. The Precompile property is already set to True. 2. I have already verified that the script was compiled. Any further suggestions?
I am having some problems with the loading of tab delimited text file (source) to a SQL Server table (destination) using the SSIS data flow task. Package has been executed successfully with no error msg. The number of rows in the text file also matches the number of rows in the SQL table. But, when I check the content of the table, I noticed some of the columns contain NULL which supposed to have value. This happens not to all the rows but only to some rows. I did some testing by removing some rows from the beginning, middle and end of the text file and re-run the package but the result is quite inconsistent. Sometimes, the field got filled, but sometimes, it just contains NULL where it supposed to have value.
I am experiencing an error where the ssis data flow task would freeze and stop data export from a oledb source to a text file. It doesn't generate any errors the ssis package would just hang. This only happens when I run it in 64 bit mode. When I change the mode to 32 bit the ssis never freezes and runs fine. Has anyone experience this? Is there a fix so I can run my jobs in 64 bit mode?
I need to call a stored procedure to insert data into a table in SQL Server from SSIS data flow task. I am currently trying to use OLe Db Destination, but I am not sure how to map inputs to OLE DB Destination to my stored procedure insert. Thanks
I have a relatively simple SSIS package that I'm building for a data mining process. The package starts with an OLE DB data source, passes the results of a SQL Command (query) along to a conversion step, which then gets sent to a Term Lookup task. The Term Lookup then writes the result to an OLE DB Data Destination. Pretty simple. The OLE DB data source query returns about 80,000 rows if you run it through SQL WB. The SSIS editor shows 9,557 rows make it out of the source, and into the conversion step, 9,557 make it out of the conversion and into the lookup, and about 60,000 rows make it out of the lookup and are written to the results table. Then the package fails with the following errors listed on the progress screen. I was assuming that the 9,557 was some type of batching that was occurring in the process, but now I'm not so sure.
Thoughts?

I have a package that loads staging tables from an Oracle source DB. In the data flow tab I have 30+ read table/write table task combinations. When I run the package 3-4 of the read/write combos execute at a time. What I'm trying to control is the priority order of the combo execution. My goal is to minimize to total load time by having the larger table transfers run first and the smaller table transfers fill in until they are all complete. Currently, the largest table (16 million) transfers last (because it was the last combo that I created?).
I am creating a staging database in which I am loading required tables from 2 different sources. I have 30 different tables to load from source 1 and 10 different tables from source 2. This is the way I am doing, in Control flow task I am using Sequence container and in that I included the data flow task, the data flow task has source OLD DB connection from where I select the table and then destination OLE DB connection where I load the data. So for 30 tables I have one Sequence container with 30 different data flow task and each data flow task has OLE DB source and OLD DB destination. I wanted to find out if this is the efficient way to do, or if there is any other way to do this. And for source 2 shall I put in another package or shall I use the same package with different sequence container and follow the same steps as for Source 1 tables. Please advice. Thanks,
I am working on an SSIS project where I create two flat files for submission to a data contractor. This contractor requires a control record be the first line in the file. I create the control record based on the table information being exported.
What I would like to know is, is it possible to utilize the Header Section of the Flat File Destination Editor to insert the control record? And, as it is dynamic, what kind of coding must I do in order to utlise this functionality?
I need to extract data to send to an external agency in their supplied format. The data is normalised in our system in a one to many relationship. The external agency needs it denormalised.
In our system, the parent p has p_id, p_attribute_1, p_attribute_2, p_attribute_3 and the child has c_id, c_attribute_a, c_attribute_b, c_parent_id_fk
The external agency can only use a delimited file looking like
where n is the number of children a parent may have. Each parent can have 0 or more children - typically between 1 and 20.
How can I achieve this using SSIS? In the past I have used custom built VB apps with the ADO SHAPE command but this is not ideal as I have to rebuild each time to alter the selection criteria and and VB is not a good SQL tool.
I met a problem when trying to pass values to a SQL statement through parameters. It's a data flow task. I used the OLE DB connection. My statement is like the statement below(the real statement is little complex):
Select * from myTable where mydate>? and mydate<?
I used the "set query parameter" dialogbox to bulid two parameters varStartTime and varEndTime, the values for the two parameters were set to "1/1/2005" and "12/30/2006" respectively. But when I click the "Parse query" button, I got errors
Parameter Information cannot be derived from SQL statements. Set parameter information before preparing command.
I have referred to the posts, but the problem still exists. Any help will be highly appreciated. Thanks a lot!
