Is It Possible To Read Flat File Data From A Variable?
Nov 6, 2006
Hi,
I'm relatively new to SSIS and I've been tinkering with the XML and Flat File sources.
I noticed that in the XML source it is possible to tell SSIS to read the XML data from a variable. I didn't see a similar option for the Flat File source.
Does anyone know if it is possible to read flat file data from a variable when using the Flat File source?
Public Class ScriptMain Inherits UserComponent Dim smpid As String Dim Prdt As String Dim rcnt As Int64
[code]...
Using the Vb script above I am expecting to read the first row from a flat file source and transferring the data into two variable using script component.
I get the following errors one after the other:"The collection of variables locked for read and write access is not available outside of PostExecute." "Object reference not set to an instance of an object."
I'm reading a Flat File. The 1ste record containts special Info that is needed for first preparing the database on a buld insert of the remaining lines.
How could i realize this, just read 1 line, store some of that data into variables, execute some proc's and then read the rest of the file ?
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?
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
Hi, I want to read only the first row in flatfile. I do not see this option on "Flatfile connection manager editor" setting wizard. Any work around for this?
I have a few flat files that I need to read a date from. The date will always be on Line No 4 and will be in YYYYMMDD string format in chars 2-9 of line 4
Here's what I have so far to convert the string YYYYMMDD into date format... I don't know enough VB to be able to just hit Line 4... I am sure it's simple so could someone pelase put me out of my googling misery
Code Snippet
Public Sub Main()

Dim oStream As New IO.StreamReader("Z:TreasuryFilesdeals.dat")
Dim strReadLine As String, filedate As Date
'??? how to just read a date from the fourth line of the file ??
'strReadLine = oStream.ReadLine()
strReadLine = "A20050331" 'sample string variable
'convert the fourth line of the flat file to a date format
I have a simple CSV/XLS dump that i need to put up on the server. I would need to create a file output daily and need a variable name to identify them easily. I have the problem of naming it in the "connection string" easily and i have tried variables and expressions too. I am new to this so please need help. Thanks
How can I write the value of a variable to a flat file in SSIS?
In particular, I'm creating a flat file I'm storing the data of a table. I'd like to add a header that displays the value of a variable that contains the record count. How can I do that?
I have a number of DTS packages I am trying to convert and am totally new to Integration Services.
I have a flat file that I reference to get a date that I use in some SQL statements in the package. It seems like the best way to do this would be to create a variable to hold the date and set it at run time from the flat file. I've been searching the documentation and the forum and can't figure out how to do this. This is so basic that I feel like an idiot putting it on the forum but I need some help. This whole Integration Services thing is a big shift from DTS (which I eventually became pretty good at) Now I'm back to ground zero.
Any help would be appreciated. If you can direct me to any basic training resources that would be cool too.
I am trying to make a SSIS package that will loop trough all files in a directory and load information from them.
I can do this with Raw File Sources since they allow me to use a variable name as the file path, but I cant seem to do the same with Flat File Sources. Is there a way to change the connection to a Flat File Source on each iteration of a loop? Actually, if this is possible with all types of file sources (like excel files) I would love to know about it too.
I was thinking about renaming the file through a script task but that does not seem like the most elegant solution so decided to see if some one here knows of a more proper way before I go that direction.
I have a few flat files that will be retrieved from some SFTP server. One of the flat file will act as a terminal file where it will specify the total number of records expected in each other the flat file.
Data in the terminal.txt FileName TotalRecords File1 1000 File2 1500 File3 2000
So, before transforming the data from the flat file sources into the target destination, i wish to do a row count checking for each of the flat file source to make sure that the number of records in the flat file source is tally with the number of records specify in the terminal.txt file. I'm able to get the number of records in each of the flat file by using the RowCount component but don't know how to get the data out from the terminal.txt file in order to make a rowcount comparison.
Can any1 help me on this? Or is there any other way we can do to make sure that the flat file source is alright before proceeding with the data transformation task?
Okay, can I assign line x of a flat file to a variable, parse that line, do my data transformations, and then move on to line x+1?
Any thoughts?
In other words, I'm looking at using a for loop to cycle through a flat file. I have the for loop set up, and the counter's iterating correctly. How do I point at a particular line in a flat file?
I have a variable defined as "Country". Based on the value, the header row printed needs to be different.
I've already created a 'HeaderRow' variable that I'm able to set using a script task. But how can you set the Header text value at run time from the variable? There is no expression defined for the Header with the Flat File Destination object, and when I attempt to reference the HeaderRow variable as the Header text, the variable name is printed as the header.
Another approach I tried was to write the Header Row separately through another data flow task, but the issue here is: what is the input source when all you have is a Country variable?
I'm doing a simple ETL that reads a database table and dumps the content to a text file. The text file will be named Employee.txt. This file name will remain the same across my environments, but I may want to vary the directory location to where I want this file dumped.
So, I defined an environment variable called "DataTargetDir" in all my environments. Now, I want to utilize this variable in the "File name:" box within the Flat File Connection Manager Editor. How do I do this? I'm thinking I can write something like "%DataTargetDir%Employee.txt" in the "File name:" box, but it's not working.
RE: XML Data source .. Expression? Variable? Connection? Error: unable to read the XML data.
I want my XML Data source to be an expression as i will be looping through a directory of xml files.
I don't see the expression property or the connection property??
I tried setting the XMLData property to @[User::filename], but that results in:

I have a requirement wherein I have to setup the flat file connection manager to accept columns on fly. Meaning I want to retrieve list of columns/column count from the database when the package is run and set the connection manager with those many columns.
My task is to read the filename from a database table and transfer the flat file data in to a table. In SSIS,I am able to fetch the file name using a Data Reader Source; but how to pass this fileName parameter to Flat File Source ?
In DTS I have used ActiveX script to pass filename variable as flatfilecon.Source. Any help ?
I am creating one SSIS package where my source is oracle. I have transferred the data from Oracle to flat file as per client requirement.I have to create single package for 2 country 1 is US and another is CANADA Columns are below
ZONE_ID, ZONE_NAME Zone Id having data like 10001,10002,10003,20001,2002,2003
Where zone_id start with 1000 is US Zone and Zone_Id start with 2000 is Canada Zone.
For US: 1. Load geography data from DB tables into flat files 2. Load geography data from flat files to Spectrum DB tables
For Canada: 1. Load geography data from DB tables into flat files 2. Load geography data from flat files to Spectrum DB tables
Now I want to look from flat file if Zone_id start with 1000 then it must go to US_DFT and if Zone_id start with 2000 then it must go to CANADA_DFT.
I am downloading a webpage as a text file in order to read a specific string to assign it as a variable/parameter in order to create an output file name. I would like to know how would I be able to look for a specific string and output as another variable for the rest of the package.

To explain it a more better way, I have a sample webpage text here. I should be searching for "FullCountyLoanLimitList" appended by the current year (like FullCountyLoanLimitList2015) and copy the entire file name in the text file and assign it to another variable so that I can download that specific file using WebClient connection.
First I want to say thanks to the folks how have helped me over the past week or two. I'm missing a crucial piece of insight. How do I read a single piece of data from a SqlDataSource which only hold one row of data into a declared variable? string zUserName = SqlDataSource.(get the value in the row that is labeled UserName) It really doesn't matter to me whether it is an SqlDataSource or some other data container that hold the data I've selected. My goal is to be able to read some data from some predefined datasource into a declared variable. If I am approaching this problem in the wrong way any advice or article links you could give me would be grealy appreciate. Thanks, Bill
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
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.
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
I am transferring data from an OLEDB source to a Flat File Destination and I want the column width for all of the output columns to 30 (max width amongst the columns selected), but that is not refected in the Fixed Width Flat File that got created. The outputcolumnwidth seems to be the same as the inputcolumnwidth. Is there any other setting that I am possibly missing or is this a possible defect?
I am running my package in sql server 2012, in which i am giving network path for flat file destination. And its working fine. But if i give m local path, its giving me error " cannot open data file" ...
How do I insert data from a flat file or .csv file into an existing SQL database???
Here what I've come up with thus far and I but it doesn't work. Can someone please help? Let me know if there is a better way to do this... Idealy I'd like to write straight to the sql database and skip the datset all together...

I want to load flat files into a single table. But the flat files can have variable number of columns upto a maximum of 10 columns. The table in my database has 10 columns in it. So in case if I load a flat file having 6 columns then rest of the columns in the table will have nulls. I don't want to use script task for this as I am not good in writing C#code.
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
