Merge Data From Oledb Source And Flat File
Feb 26, 2008
Hi All,
In one of my SSIS Interface I have to Merge data from a Oledb source and a Flat file source.But after I read from the flat file I have do a basic validation of the file for the length of header,detail and trailer records and then process further.The above Validation I am doing within Script Component.If the validation fails the flow should pass out of the DataFlowTask without Initailsing the Oledb source.
But the problem is i am not able to connect anything to the Oledb source,i.e Oledb source is not taking any incoming Pointers.
Earlier I had done the same Validation in Control Flow Task,but then the interface was reading the same file twice,once in the Control Flow Task and then again in the DataFlowTask.Which i should avoid now.
I hope many of you could have come across such a problem.
Any help on this will be appreciated.
cheers

I am working to archive some old data from a data warehouse using SQL server and SSIS. The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required. Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.Â
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.

Hi,
I'm using an OLEDBSource to select some data and then putting to in a Flat File destination.
However, when I look at the data in the OLEDBSource, they´re like this:
1. id
2. name
3. address
...but in the flatfile it comes out in the wrong order.
How can I fix this?
Thank you so much.

I have a
table with column (call it Rate) defined as decimal(18,4). This column
can have any positive decimal value. When the value is less than 1
(e.g. 0.1234) strange things are happening in SSIS.
To set the scenario ...
If I do a select in Management Studio, the value is correctly displayed as 0.1234
If I do the same select from the command line via OSQL, I get .1234
If I do SELECT CONVERT(char(6), Rate) from OSQL, I get 0.1234 (which is what I want)
In SSIS I have an OLE DB Source which defines the SELECT statement to use, and that maps straight to a Flat File Destination.
The
default column type in the flat file connection manager is DT_NUMERIC,
Precision 18, Scale 4. I Set InputColumnWidth to 6 as that's how I need
it in the flat file. The value appears in the file as .1234
I
change the SELECT in the OLEDB Source to apply the CONVERT(char(6),
Rate), and change the column type in the connection manager to DT_STR
length 6. Output is *still* .1234
How can I get the output column in my file to show 0.1234 ??
Greg.

Hi, all,
I have this SSIS data flow ( Flat file to sql server) that I want to add a step to redirect any "bad" data instead of fail out.
I had the red arrow hocked up to a sql new table to dump the bad data, but the flow still failed.
Here is the first error, and I knew what was wrong. A description field in that line has pipe(|) character in it, which also happen to be the column delimiter in this case.
[Flat File Source [1]] Error: Data conversion failed. The data conversion for column "Column 22" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
I knew if I fixed the data, every thing will be fine, but I just want to use this redirect feature of SSIS. Is there a place where I can turn off validation, or do something to make it work?
Thanks!

I am attempting to pull in data from a flat file data source that contains dates in the following format "01012007 10:22" which translates to Month Day Year and Military Time. I want to turn this into a DateTime format so that I can insert it into the proper column. I have a SQL statement which will do this (see bellow), but I can't figgure out how to run the statement on the data before it reaches its destination.
Can anyone help?
The code is:
Code Block
cast(convert(varchar(16),(substring( REPORT_RUN_DATE,1,2 ) + '/' + substring( REPORT_RUN_DATE,3,2 ) + '/' + substring( REPORT_RUN_DATE,5,10 )),1) as datetime) AS REPORT_RUN_DATE

Hi,
I am trying to impliment a SSIS package where data source is a Flat file(.csv) file and destination is a sql server database.
The problem is my data source a flat file which consists of thousands of rows which are manually entered, so there is always a chance that in some rows they may miss a column value while entering data which results in an error.
Example: My flat file has headers like Sln, Name, Age, Designation. While entering data they may miss age and type it as 1,aaa,Consultant,,
Using SSIS package i want to track all row number in the flat file where data is entered wrongly so that i can correct only that row instead of checking all rows each time when my SSIS package throughs an error. I want to get all the row numbers in a sql server database which are wrongly entered.
Any suggestions are sincerly apriciated.
Thanks in advance
Regards,
gcs.

I was getting the product error associated with the full version of SSIS not installed so I ran the installation again and selected the Integration Services check box.
Now when attempting to import data into a database, the drop down list doesn't have a flat file option.
How do I import data from a txt, csv file?
Thanks

I'm getting a very strange potential loss of data error on my flat file source in the data flow. The flat file is fixed width and the column in question is defined as numeric [DT_NUMERIC]. The transform runs great if this column IS NOT A ZERO. As soon as a zero value is found, I get the error. It errors on the flat file source, so I haven't been able to use a data viewer to see what's going on.
Please Help!?
Thanks,

Each day I receive a file with a different name. For example, the name is filename_mmddyyyy.txt where filename_ stays constant and mmddyyyy is the date of the file. The file is always in the same format.
I want to build an SSIS where I pass it this file name. I can write a script to generate the correct file name. How do I build the SSIS so it can accept the input parameter and find the correct file to process?
Thanks

Hello,
I have a flat file source with ragged right format. It has three columns.
My package fails when the last column has null values.
It says "The value could not be converted because of a potential loss of data".
So tried lot changing row delimiter and column delimiter but to no avail.
So any idea on this is well appreciated.
Thanks in advance.

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 writing a package that will process delimited flat files that will come in one of a few different versions. Within each flat file, the number of delimited columns will be the same, but each version of the file has a different number of columns. I have tried configuring the flat file data source to expect the version with the largest number of columns, but it will then throw away rows that have less than this number of columns (warning: There is a partial row at the end of the file).
Is it possible to use a single flat file data source that will work with all of the different width files?

I'm having a problem using the Flat File Source while using the underlying .Net classes to execute SSIS Packages. The issue is that for some reason when I load a flat file it Empty's out columns randomly. Its happening in the Flat File Source Task. By random I mean that most of the times all the data gets loaded but sometimes it doesnt and it empty's out column data. Interestingly enough this is random and even the emptying out of columns isnt a complete empty, its more like a 90% emtpying. Now you'll ask that is the file different everytime and the answer is NO. Its the same file everytime. If I run the same file everytime for 10 times it would empty out various columns maybe 1 of those times. This doesnt seem to be a problem while working with dtexec or the Package Executor utility. Need Help!!

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:
Flat file 1: Bulk Import Task = 12,649,499 rows; Data Flow Task = 4,215,817 rows
Flat file 2: Bulk Import Task = 3,403,254 rows; Data Flow Task = 1,134,359 rows
Anyone have any guess as to why this is happening?

Hello,
My OLE DB Source is getting data from the following column types:
ID varchar(50), Name varchar(100), Date datetime, Currency char(3), Cost numeric(30,10)
My OLE DB Source outputs my information in the following order when I click Preview:
ID Name Date Currency Cost
When I connect the OLE DB Sorce to a Flat File Destination, it comes out in the wrong order.When I examine the "line" between them (Data Flow Path Editor) I get:
Currency DT_STR Length: 3
ID DT_STR Lenght: 50
Name DT_STR Lenght: 100
Date DT_DBTIMESTAMP
Cost DT_NUMERIC
What is the easiest way for me to change this so the Flat File Destination will output my data in the same order as the OLE DB Source:
ID Name Date Currency Cost
Thank you very much!

Hi,
I am trying to create a program that transfers tables to flat files.
At this point in time, I have suceeded in created one that creates delimited files.
However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.
Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.
I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.

Hi,
we have one requirement to run the package daily basis.
The package should run at specific time on that day.
we are using windows schedular for that.
we will have one new flatfile everyday.
Is there any process to attach this file to flat file source dynamically?
The requirement is,
The flat file should be able to read the new flatfile everyday.
we have no option change it manually, the flatfile source should have to take the file automatically at that time.
So that it can take that flatfile and load it into database table.

I am wondering how easy is to check for file locks and have our SSIS Package to wait until file has been release by the process which is using it.
Also, same question when we're writing to a Flat File (or Flat File Destination).

Hello, I wanted to do the following.
Copy a full directory from source to destination (Done)
then for each file on the destination directory,it must process that file and insert rows on the table.
So I created a foreach loop, and created a varriable aclled CURRENTFILENAME, and assigned it into the foreachloop to index 0.
Inside the foreachloop I created a dataflow task, in the dataflow task I dragged a flat file source and an oledb destination, but I noticed that the flat file source requires flat file manager, and the flat file manager requires a unique FILE NAME. I cant put this c:copia*.txt.
I took a loot at flat file source properties and it has associated the flat file manager, but I can not assign the filename to the variable from the foreach.
Any ideas please

I've been working 4 days non stop on this project, lost a complete weekend on it and I totally had it.
Please have a look at this "simple" question:
I have a for each loop that checks for csv files in a folder. The path of the file(s) is stored in a variable varFileName.
So far so good. But then I start with a data flow task and inside that data flow task I need to access one of those csv files at the time whenever it loops.
So my best guess is use a flat file source because that's the only task I see in the list that fits my question.
But the thing is, you set up a connection to a....yes right, a flat source connection and there you have to select a flat file.
But no, I don't want to select ONE file, I need to access them all as the loop goes through all files.
I'm sure this is something easy but I don't see it anymore.
I'm off taking a nap, need sleep
Could someone please point me to a direction?
Many thanks!
