SSIS Database Table To Flat File Destination With Column Headings
Sep 8, 2006
Hi,
I have a simple enough task to complete that I cant seem to find the answer to.
The task is this
Select table x from the database and write it to a flat file complete with that tables column headings.
Now Ive managed to set up an ole db datasource and selected the table and Ive also linked it to the flat file output. So now I can generate a flat file from the database. However no column headings appear in the flat file.
I cant seem to find anywhere (like a checkbox) that will also output the column headings to the flat file.
Now I can add in Headings manually in the properties of the Flat File Destination object but the columns that appear in the flat file dont appear to be in the order that I requested them in the SQL.
So the question is how do I automatically have the column headings appear for flat file output (ideally without me having to manually add them in).
If it cant be done and I have to use a vb.net script instead then would anyone have an example script of how to do it?
Thanks in advance for anyone who manages to answer this.
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 trying to use a conditional split task so that I can check for specific fields. If the value doesn't exist I am piping the records to a derived field task, where I add an error. I then try to send these records to a flat file destination so that I can keep track of them. However, when I execute the SSIS data flow task I get the following error
[Log Invalid Records [5496]] Warning: The process cannot access the file because it is being used by another process.
This file isn't being used by any other process as far as I can tell, and the only process using it is the SSIS task trying to write to it.
If anyone has any ideas, then I would really really appreciate it
How do i import a Varying Column Width Flat file into a Table using SSIS?
I have a flat file that has 4 columns with varying width Like I should read the file as Col 1 - (1 to 10 Characters) Col 2 - (12 to 21 Characters) Col 3 - (22 to 35 Characters) Col 4 - (36 to 38 Characters) At the end of the record is a "LF"
I think "Fixed Width" Columns allow me to define a standard column length for all the columns.. Right?
TABLE_NAME DESC CODE tab1 table1 A tab1 table1 B tab1 table1 C tab2 table2 D tab2 table2 E tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code] data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.
how do I make the output columns padded with extra space ? I intentionally set my output width larger than the input width, but the generated file is still jamming all the columns next to each other
[Flat File Destination [46500]] Error: Data conversion failed. The data conversion for column "Column 0" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page." What does this error mean exactly?
I am taking columns from a flat file source. Then I am adding some new columns then rewriting the file to a ragged file format with fixed column values. I've taken the Destination component off and it works fine. So I know it could be the destination component but what could it be? Any ideas?
I created a ssis package which exports the data from oledb source to flat file (csv format). For this i have OLEDB source and Flat File as destination. I generate the file and filename dynamically with the column names in the first row. So if the dynamically generated file name already exists , then i want to append the data in the same existing file. But I dont want to append the column names again. I just want to append the rows to the existing rows.
so lets say first time i generate a file called File1_3132008.csv.
Col1, Col2 1,2 3,4
After some days if my ssis package generates the same file name i.e. File1_3132008.csv, this time i just want to append the rows to the existing file. So the file should look like this- Col1, Col21,23,45,67,8
But instead my file looks like this if i set Overwrite propery to false
Col1,Col2 1,2 3,4 Col1,Col2 5,6 7,8
Can anyone help me to get the file as shown in the highlighed
I set up a connection file in order to move data from sql to csv files. I should be at the last step, the data flow. but:I don't see any flat file in my destination assistant.
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.
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?
hi - I am totally new to SSIS etc and SQL 2005. I have a dts task to recreate in SSIS. I have done most of them and muddled my way through, but this basic problem has got me stuck. When mapping columns from my file to my ole db output table, I want to map one input column onto two output columns, but it will only seem to let me select one destination column for each input? I have tried shift/alt/ctrl etc to try to get it to map to both columns but it wont have it. How do I do it?
Also, somehow my Dataflow Sources tab has gone from the toolbox, and I can't seem to get it back any way - I switched on everything I could see and all components etc, but it is not in there as an option. How do I get it back in the toolbox?
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 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 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 build my SSIS package based on the above file.But now i receive files with different columns order let say
lastName,FirstNamr,Address l1,f1,a1 L2,f2,a2 or Address,FirstName,LastName a1,f1,l1 a2,f2,l2
every time i receive multiple files in different order and i have to remap all my mappings. These are just a few columns and i have like 20 columns and the order can potentially change any time. so every time i have build new packages remap them etc.
through normal c# code it pretty easy. I tried to add script here but the script also needs a source and mapping so there is also a mapping issue. Is there a better way to do this.
I hope this is easy stuff for you.. First of all i searched the forum but didnt exactly find what iam searching for:
I have a File folder which contains 1..n Files of the same type. The files contain a DateValue at the beginning of each row. I now want to read the first Record of the file - extract the datevalue and search in my Importtable if there are any records with that Date. If there are allready Records with this date i know i allready imported that file and skip it in my For each File Container. If no records where found I want to copy them from the file to the table.
So I have a flatfile source and thoght I just make an oledb command task afterwards which looks like "Select count(*) from Import where Processdate = ?. and then a conditional split if the count == 0 or not... but i have problems getting the Count value out auf the OLD DB Command Task because everytime I try to add an outputcolumn i get the message: "An Output cannot be added to the output collection" and since there is no possibility to map an expression to the result...
I tried to workaround the problem using a lookup task.. but that seems to be the wrong way.
Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
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" ...
1. Flat File Source 2. Conditional Split, Case Good = !ISNULL(KEY) Case Error = ISNULL(KEY) 3. Case Good -> Writes to Good Flat File (with timestamp in the title) 4. Case Error -> Writes to Error Flat File (with timestamp in the title)
Most job runs have no errors but the error file is created as a zero byte file anyway. If there are no error records I don't want the error file created. How might I accomplish this?
i was used the Follwing DataFlow for my Package.using Oracle 8i
FalteFile Source -------------> Data Conversion --------------->OLEDB Destination (Oracle Data table)
using above control flow to map the Source file to Destination . When i run the SSIS Package teh Folwing Error i got
"Truncation Occur maydue to inserting data from data flow column "columnName " with a length of 50 "
regarding this Error i i understood its for happening Data Length . so that i was changed the Source Column Length Exactly Match with the The Destination table.
still i am getting this Error. pls any one give me a solution . SHould i Change the DataType also?
I am using SSIS to create a weekly data extraction that will be emailed to an external agency. I can extract the data, create the file and email it without any problems but I want to compress and encrypt it before I send to give some measure of protection to sensitive data it would contain.
If I did this manually, I would simply use Winzip to compress and encrypt the file to be sent. How can I achieve a similar result programtically?
I have created a package and when i was trying to configure a flat file destination, i am getting the following error:
===================================
The component could not be added to the Data Flow task. Could not initialize the component. There is a potential problem in the ProvideComponentProperties method. (Microsoft Visual Studio)

Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
i am trying to load almost 15 csv files to my oledb destination can i use for each container to map the source columns dynamically to destination table during data flow task
