I have a text file that is comma delimited and im pulling it in with a flatfile connection manager. I want to read some of the data, then output another flat file but in a fixed column width. What settings do I made to the connection manager of the output flatfile ?
View 9 RepliesHi,
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.
Currently we're working on an SSIS package to extract data from a SQL Server database to several fixed width flat files.
Some of the data needs to be formatted/converted in a certain way
DateTimes need to be formatted in ISO8601Booleans need to be 0/1 instead of False/True...Has anybody any idea what the preferred approach (best practice) would be to do these conversions?Convert everything in the select query? What about readability of your query?
Do it somewhere in the package? If so, how?....
I am new to SSIS and am having trouble with automatically setting up the destination output columns.
I am sure there must be an easy way to do this.
My table (source) has 86 columns in it of varying lenghts.
In my connection magagers, I have created one for the SQL Server (source data) and one for the flat file (destination output).
I have also created an OLE DB source data object and a destination Flat File object and set them up to the respective connection managers.
Finally I have linked the source to the destination.
Now when I look at the source, it shows me all 86 columns.
When I open up destination, there are no columns set up.
Problem: do I have to type in all the columns manually in the connection manager for the Flat File?
I would think there would be some automatic way that it would self-populate the columns over to the flat file destination.
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?
Any inputs will be appreciated.

Hi All,
I have a simple SSIS package that runs a query on the db and outputs a fixed width flat file. I have all my column widths defined and in the connection manager i can preview the output. Everything looks great. All the fields fall where they should and each record is on it's own line.
When i run the SSIS program and then go open my text file with a text editor the ouput is all on the same line. I have tried changing my file format from fixed width to ragging right and adding a row delimiter but that doesn't work either. I feel like i'm missing something small here. It could even be an issue w/ my text editor (although i've tried to open the text file in multiple editors). In the flat file connection manager I have my file defined to be 187 characters long, So figure every 187 characters it should output a new line (it should add the carraige return right?).
Has anyone encountered an issue like this?
Any help would be much appreciated.
I have like 100 columns and most of them work fine, but some will not work. I need to select the columns with correct width for fixed width flat file.
Here is typical SQL statment that works for most of them.
left(RTRIM(A.City) + Replicate(' ', 25) ,25) as [City]
The above one is not working, but many other works fine like the address. Why would it work for some, but not others?
It works fine if I use any char, but not space. i.e.
left(RTRIM(A.City) + Replicate('*', 25) ,25) as [City]
I am trying to export data from a query in SQL Server 2005 SSIS to a flat file destination. Everything works fine except the rows returned from my query are written to the flat file in one long string (i.e., without line breaks). I have tried appending a new line character to the rows returned from the query but that only throws an error when the package is executed. My rows returned from the query are 133 characters wide (essentially only one column per row) so I have set the properties accordingly for a fixed width file format with 133 character wide rows.
Any suggestions or ideas on how to correct this would be greatly appreciated.
Thank you,
Michael
Hi,
There's a lot of information on importing data from text files, but not a lot on exporting data to text files... I've checked but found no info on this.
I'm trying to export data from SQL Server to a fixed-width flat file and wondering if I'm doing it the right way.
I use a view as source (using a OLEDB connection manager) and I can see the data without problem.
I defined a Flat File Destination (using a flat file connection manager). When setting up the flat file connection manager, I am asked for a file... Does this mean one should create manually a template file with the desired output format? So I used a production file as template since we're replacing an existing process.
After having set up everything, I run the SSIS only to see all the data on the same row. There are no CRLF...
When I create the file connection manager, there's no way to mention the row delimiter. In the properties I see a "Row Delimiter" field and when I try with "{CR}{LF}" it makes no difference. Interesting to note that, contrary to the HeaderRowDelimiter field, the RowDelimiter field has no drop-down control to give choices.
So I had to return the CRLF as the last field of the source view (SELECT .... ,'CRLF' = CHAR(13) + CHAR(10) FROM ...) to make it work.
Seems odd... Is it the way to go?
Thanks
More SSIS woes. DTS was so much easier.
I have a flat file. It's fixed-with with CRLF record delimiters (a.k.a. Ragged Right format).
Some fields are null, and represented by the text NULL.
I'm trying to import the file into SQL via an OLE DB connection. The target table is a SQL 2000 data table. Two of the fields in the target database are of type smallint.
When I run PREVIEW on the data source (Flat File), everything looks good & correct. I added the convert columns task to convert my strings to smallint. This is where things go haywire.
After linking everything up, the conversion gives me a "Cannot convert because of a possible loss of data." All of my numbers are < 50, so I know this isn't the case. Another SSIS bogus error
My first instinct is the SSIS doesn't understand that NULL means null. I edited the file and replaced all instances of NULL with 4 emtpy string chars. Still no good. It seems to be having a hard time parsing the file now.
I dropped the convert task and tried editing the data source, and set the two smallint fields to smallint instead of string (SSIS formats). I get the same conversion error.
Changing the NULL values to 0 fixed the problem, but they're not 0. They're null.
Short of creating another script that converts all zeros to NULL using the aforementioned hack, I'm out of ideas.
I'm I missing something or is SSIS just incapable of handling nulls in fixed-width flat file formats?
TIA
We're having issues exporting a set of data from SQL to a fixed width flat text file by just doing a right click on the DB, then choosing Tasks > Export Data. You can not specify a row delimiter when you choose a Fixed Width format. The only way around this that we've found is to specificy char(13) and char(10) at the end of the SQL select statement. Without row delimiters you end up with 1 giant record rather than 20,000 regular sized records. Is there any other way around this that we're missing?
Using Ragged Right is not an option either since the record lengths will be inconsistent if the last field doesn't contain a consistent length to the data.
Thanks,
Mike
I am sorry, I am posting this message again, since I did not get anyreply.I want to export a table into a "fixed width" file using SQL 2005import export wizard.This is the version I have:SQL Server 2005 - 9.00.2047.00For some reason it joins all the rows together. For EX: if the tableis like this:Create table Mytable (col1 varchar(50) null, col2 varchar(60) null,col3 varchar (100) Null)Insert into MyTable values ("abcdef", "12345", "8900")Insert into MyTable values ("xxxxxxx", "11111111", "22222222")Insert into MyTable values ("yyyyyyyyy", "5555555555555555","6666666666")Insert into MyTable values ("abcdef", "12345", "8900")Insert into MyTable values ("xxxxxxx", "11111111", "22222222")Insert into MyTable values ("yyyyyyyyy", "5555555555555555","6666666666")It is not exporting every row in a single line. Actually if I open itin "Ultra Edit", it is all in one line.I used to do this regularly with SQL 2000 import export wizard and itexported every row in one line.I looked at the setting:The header row delimiter has {CR}{LF}Code page has 1252 Ansi-Latin.In the Advanced tab:String:dt_str.I tried changing the header row delimiter to just {CR} or just {LF}.Also I tried changing the string to dt_text and nothing seems to help.Please help.Thank you

View 3 Replies View RelatedI can't use DTS nor DTSwizard as I need to put it in a .sql and run it through a command line via .bat file (it's more for the users).
Each row ends with an EOL character, the fields are all fixed width, but I have a little problem here, some rows are empty but just with a EOL character.
How shall I go about it?
many thanks! :D
When I use SQL 2000 DTS Export to create a fixed length flat file, the data rows are delimited by carriage return-line. Which means that when I open the flat file in a text editor like UltraEdit or WordPad, the data rows are broken out nicely (row ends at the max row length position and new row starts at position 0).
But when I use SSIS to create the file, the whole file is displayed as one line in WordPad. The data rows don't end at the max row lenght position in ultraEdit neither. From Flat File Connection Manager's Preview page, I can see the data rows are displayed properly.
Now I wonder if the flat file destination is a true fixed length file.
Hi all,
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?
thanx
Is there a better way to handle fixed width flat files than the built-in SSIS capability? I have a fixed width file with over 400 columns and it looks like I need to manually click lines where each column starts/ends (quite tedious and prone to error). I have an excel version of the spec with start position, length, and data type for each column. So far it looks like the only way to automate this task is to somehow automatically generate the package XML from the spec and paste it into the dtsx file. Anyone know of a better way?
View 7 Replies View RelatedI'm sending the results of an SSIS data flow to an fixed-width flat file output, but instead of getting separate rows of data, like so:
row1data...
row2data...
row3data...
etc...
I get:
row1data...row2data...row3data...etc...
Is there some setting I'm missing in either the flat file output or the file connection to turn this on?
Hello Everyone,
Please do inform me, how can I check if there is a new record or changed record from the source.
NOTE: my source is Flat File and destination is Oracle Table.
What is needed from my side is the history load (Type 2).
This is not possible thru SCD component in Integration Services, If my source is Oracle (Even after I had added the parameters in my OLE DB)
Please do inform me about this process. Very important.
Thank you
I am bring a date from a OLE DB Source (SQL Command) as [select cast(convert(varchar,getdate(),101) as varchar(10))] to a Flat File Destination (CSV File). The data in the source is show as "1/1/2007", which is how I need it to display in the file. The flat file defaults to showing the data as "1/1/2007 00:00:00." I did change the destination field to a String, and still, I geting the timestamp. I tried using a data conversion transformation, and I am getting bargage data when converting the date to a string.
Can any one give me insight on how to populate a date into a comma delimeted file as "1/1/2007", not "1/1/2007 00:00:00."
Thanks in advanced.
Good day everyone,
I have implemented a simple package that has only a Data Flow Task in the Control Flow. The corresponding Data Flow Components are as follows (in the correct order):
1. A Flat File Source adpater which parses a file containing circa 1 million rows.
2. A Script Component that generates IDs for two of my destination tables.
3. A Mulicast Component that distributes all the columns retrieved from the source file as well as the 2 generated keys.
4. Four OLE DB Destination adapters where I insert the data from the different columns together with the generated keys as primary or foreign keys respectively.
My questions are mainly about how the "Flat File Source" and "OLE DB Destination" work behind the scenes.
Questions:
A. "Flat File Source" adapter:
Does the "Flat File Source" adapter load all the rows from the source file into the memory and then start pushing the rows one by one into the data flow?
My concern is actually about the huge sizes of my import files, which might eat up the memory.
Or does the "Flat File Source" adapter load a certain number of rows, pushes them into the pipeline and then fetches the next batch based on a certain configuration?
B. "OLE DB Destination":
I have set the four OLE DB destinations to "Fast Load" with a commit size of 5,000.
Can I ever run into the problem of having for instance 10,000 records inserted in Table1, but only 5,000 inserted in Table2. The error case I am thinking about is as follows:
After the second commit on Table1, an erroneous record occurs during the insertion in Table2. Thus, the second commit for Table2 gets rolled back and the whole package fails.
In this case, I get an inconsistent state in my database.
In other words, how can I synchronize the commit operation in all my destination tables, s.t. they either all commit the same batch or all do not commit it?
Thank you in advance for your support.
Regards,
Samar
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
View 2 Replies View RelatedHi,
I have a data task with the following requirements:
1) Run query against database to retrieve rows
2) Add header and footer row to the result set. The footer row must contain a count of the records.
3) Write the rows to a fixed width file if there were any data rows
I have got to the point that I can create the file (using a set of tasks that includes derived columns, sorts, aggregation and merges). However the file is created regardless of whether there were data rows returned.
I can't check the row count before proceeding as this isn't set until the data task ends. And if I try to split them into separate data tasks (so that I can access this variable and perform conditional execution) it becomes harder to access the original rows.
Do you have any recommendations on the best way to achieve this?
It all seems to be very complex and I'm starting to feel that it would be easier to do this outside of SSIS...
Please help me to keep the faith!
For those interested this is a slightly simplified version of what I have so far (all within a single data task):
1.Run dummy sql to create header row 2.Run main SQL to retrieve rows
| |
| 3.Multicast
| | |
| | 4.Create footer row by doing sum() in aggregate task
| | |
| 5.Merge body and footer
| |
6. Merge header with body and footer
|
7. Create fixed width file
Hi all,
I am passing flat file source as a variable to Dtexec Utility. (like package.variables[User::varFileName].Value;"D:sourcedata.txt).
Destination table is having one more column.
I want to add custom value in that column at run time by parameter to Dtexec(User::varDate)
I dont know how to do it, please help me.

Can someone tell me the difference between the Flat File Source Output - External Columns and Output Columns ?
I always end up changing the datatype properities in both to make things work :-)
I am moving data from a flat file source to a SQL Server table. But I want to add a columm that IS in the destination table, but NOT in the source file. Say the table column name is XXX in destination table, and there will be a global variable called @[User::XXX] that remains constant throughout the package. I would like to put the variable value into the destination column, even though the source file does not contain the field. Is there an easy way to do this?
View 4 Replies View RelatedI am attempting to import a fixed width file into a SS2005 table and am having problems when importing a date that has no value in it. The table will allow nulls.
The date is in dd/mm/yyyy foramt and when there is no date then there are 10 spaces. When transforming the data I TRIM the data down using a derive transform script so all there is, is an empty string. When the file attempts to load I get the following message:
[OLE DB Destination [2238]] Error: There was an error with input column "paid_date" (2306) on input "OLE DB Destination Input" (2251). The column status returned was: "The value could not be converted because of a potential loss of data.".
How can it potentially lose data when there is nothing to lose?

Export to Fixed width text file
I am trying to export a table to a fixed lenght text file, there is only flat file option and that does not put LF/CR at the end of row, is there any solution?
Hi,
I was trying to import a fixed-width file to a sql 2005 table.
The total record lenght is 1500. I was trying to import it to a single column.
The strange thing that's happening is: SSIS is inserting only the first 32 chars of the record and the remaining are gone. I tried using nvarchar(max) and varchar(max) but of no use.
I think something somewhere is going wrong but I was unable to figure it out. Earlier I was able to load a similar file into a single column table.
My Header row delimiter is {CR}{LF}
The preview pane shows the complete record but when it transfers to the table, I'm getting 32 chars only.
Can anybody suggest any ideas to figure this out?
Thanks,
Siva.
Export to Fixed width text file
I am trying to export a table to a fixed lenght text file, there is only flat file option and that does not put LF/CR at the end of row, is there any solution?
Hello,
I have a series of fixed width files, all with the same schema. I need to import the data into a SQL Server table. Each record in the flat file begins with 'D1'. The length of each record (string) is 380. There are cases where the record ends after position 193, and a new record appears in the current string beginning at position 194. So at position 194 'D' appears, and '1' appears at position 195.
In the flat file, I need to insert a line break after position 193 if position 194 = 'D' and if position 195 = '1'. I'm guessing I would do this with a Script Component Transformation. Once the file is edited, then I can bring the data into the table.
What might the script look like? If you have any suggestions, samples, or know of examples on the web you can point me to, please share.
Thank you for your help!

I'm using SSIS to do bulk inserts from fixed width files to about 20 tables in my SQL database.
The problem I'm running into is in creating Format Files for the bulk insert task to use. I've gotten the bcp command to create format files that will read csv files, but I can't seem to figure out how to get it to create one for fixed-width.
I know it can be done: http://msdn2.microsoft.com/en-us/library/ms191234.aspx
At the bottom (Section F) it shows an XML format file for reading a fixed-width file. When I manually create one of these to match one of my tables, the bulk insert worked fine.
Closest I've come is with this ( [] bracketed items are correct values, just censored here):
C:Program FilesMicrosoft SQL Server90ToolsBinn>bcp [database].[owner].[table] format
nul -c -f C:TableFMT.xml -x -S[Server] -U[Username] -P[Password]
My question is, what is the bcp command to create this sort of XML format file?
