Fixed Length File Read
Feb 15, 2006
I have a fixed-length flat file that contains about 30 columns. I have got it pretty well figured out using the flat file connection tool, but I am having trouble with the end of the line.
I know when I look at the file it is a CrLf that separates the rows, and SSIS only seems to understand this to a certain extent. It knows to go to the next line, but it also adds two rectangles to the lines, like this:
Col1 Col2 Col3 Col4 Col5
aaaaaa bbbbb ccccc ddddd eeeee
[][]aaaaa bbbbb ccccc ddddd eee
ee[][]aaaaa bbbbb ccccc ddddd e
eeee[][]aaaaa bbbbb ccccc ddddd
While this does create a cool pattern, it is a pain in the butt. The only solution I have found is adding two more spaces to the last column in the table, but the ?s just get appended there.
If anybody has any clue how to get rid of them, that would be great.
Thanks in advance

Hey All,
Similar to a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=244646&SiteID=1), I am trying to import data into a SQL Table.
I am trying to program a small application that will import product data obtained through suppliers via CD-ROM. One supplier in particular uses Fixed width colums, and data looks like this:
Example of Data
0124015Apple Crate 32.12
0124016Bananna Box 12.56
0124017Mango Carton 15.98
0124018Seedless Watermelon 42.98
My Table would then have:
ProductID as int
Name as text
Cost as money
How would I go about extracting the data with an XML Format file? I am stumbling over how to tell it where to start picking up data for a specific column.
Is there any way that I could trim the Name column (i.e.: "Mango Carton " --> "Mango Carton")?
I don't know if it makes any difference, but I've been calling SQL from my code by doing this:
Code in C# Form
SqlConnection SqlConnection = new SqlConnection(global::SQLClients.Properties.Settings.Default.ClientPhonebookConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO PhonebookTable(Name, PhoneNumber) VALUES('" + txtName.Text.ToString() + "', '" + txtPhoneNumber.Text.ToString() + "')";
cmd.Connection = SqlConnection;
SqlConnection.Open();
cmd.ExecuteNonQuery();
SqlConnection.Close();
RefreshData();
I am running Visual Studio C# Express 2005 and SQL Server Express 2005.
Thanks for your time,
Hayden.

I need to write data into a fixed column length file and was wondering the best (most efficient) way to tackle this. For example, the first few pieces of the report I'm working on now would be:
PacketID - Starting position 1, Field length 9
TransactionID - Starting position 10, Field length 9
Group number - Starting position 19, field length 10
PID/SSN - Starting position 29, field length 10
For the PID/SSN, if I have a PID it'll be 10 digits and fill the field length, if I don't I use SSN which is only 9 digits and enter a space as the 10th digit. Obviously if I don't have certain pieces of information I'll just need spaces of the specified length to satisfy the file format. I'm using SQL 2005. Thanks in advance for any help provided.

I have approximately 13 columns. Each Column has a start position and end position.. I created this in a table and defined the position, it's still not working for me.
FiceCode char(6), -- starting position 1, field length 6
StateStudID char(10), -- starting position 7, field length 10
CampusStudID char(10), -- starting position 17, field length 10
LastName char(25), -- starting position 27, field length 25
[Code] .....
I need a text output file that will define each start position.I also used: right(replicate('0',25) + cast(last_name as char(25)), 25) in my sql statement.when I add the first_name, I can't get it to start in position 52.

Will be getting new file for download from vendor to process in future. When I use DTS or Import wizard in sql server I get "could not find the selected row delimiter within the first 8kb of data, is the selected delimited valid? This is for a fixed length file. If I answer yes and continue everything is fine, until I get to the end of the record which it can't find. It basically lumps the records together. What is interesting, that if I import the same file in Access 2000, I don't get this problem. ANyone seen this before? Could not find anything on MSDN

Hi,
I am trying to upload a fixed field text file to a sqlserver table using the DTS wizard. The txt file has 111 columns and the total length of a single row is 5897. The problem is when I use the wizard to specify the starting and ending of each column, its not allowing me to specify the columns beyond the position 4095.
Is there a limitation on this? if so is there a work around ? to solve this.
Any help on this is truly appreciated.
Thanks much. :)

I have a requirement to import a file of rows containing fixed length data. The problem is that each row can be one of 5 different formats (i.e. different columns) -- where the "type" of row is indicated by the first two characters of the row. Each row gets inserted into its own table.
Could I use a simple Conditional Split to route the rows? Or is the split for routing similiar rows? Anyways, problems are never this simple...
In addition, each "grouping" of rows is related. The "first" row is considered the "primary" row (and gets a row id via IDENTITY, whereas the remaining rows in the group are "secondary" rows and have foreign key references back the the primary rows id.
Given (using spaces to separate columns and CrLf to show "grouping"):
01 MSFT blah blah
02 blahblah blahblahblah
03 boring boringblah
01 AAPL blah blah
02 blahblah blahblahblah
03 boring boringblah
01 CSCO blah blah
02 blahblah blahblahblah
02 blahblah blahblahblah
03 boring boringblah
So, the first 3 lines are all related to a MSFT record which needs to be spread across multiple tables. The next three lines are all related to AAPL, And the next FOUR lines (yes, each record can have zero, one, or more secondary rows) are related to CSCO.
(If this is still not clear, all the "01" rows will be written to [Table1] with each row having an IDENTITY value. All the "02" rows will be written to [Table2] the a FK pointing to the correct [Table1] row. All the "03" rows will be written to... and so on.
Any ideas would be appreciated.

Hi,
I am trying to import a text file that has fixed length fields.
It also has column headers repeated in the file.
The text file is delimited by <CR><LF>.
Question 1
There are certain rows that end abruptly after a column for ex:
Row 1 <col1 data>.....<col2 data>.....<col3 data><CR><LF>
Row 2 <col1 data>.....<col2 data><CR><LF>
This seems to be throwing off the text file import as row 1 seems to be importing alright but row 2 gets ignored.
This not the behaviour I want. I want row 2 to also be imported and have a default of NULL for the columns that
are not specified.
Does anyone know how to achieve this?
Question 2
This is not that serious, but currently, I do not know of a way to ignore repeating column headers.
It would be nice if there was a way, but I can always resort to T-SQL based data cleaning after the import.
Thanks.

Hi All,
I have a file that has fixed row size of 148 and fixed column size, but the file has no end of line character. I know it is wierd but a client has made the file and refuses to change the format. So I am stuck with reading it the way it is.
In Enterprise Manager, I used the Import/Export wizard and I specified fixed length and it let me specify 148 as the lenght of each line. Then it recognized the file and I was able to read it in.
I saved the DTS package and I can run it over and over again using dtsrun. However I want to do the same thing using Bulk Insert. How do you specify fixed row length for Bulk insert and how do you give it individual column lengths?
Thanks,
Shab

Hi,
I'm trying to extract data from a Flat File which is as fixed length as they come. The file has a header, which simply contains the number of records in the file, followed by the records, with no header delimeter (No CR/LF, nothing).
For example a file would look like the following:
00000003Name1Address1Name2Address2Name3Address3
So this has 3 records (indicated by the first 8 characters), each consisting of a Name and Address.
I can't see a way to extract the data using a flat file connection, unless we add a delimeter for the header (not possible at this stage). Am I wrong?
Any suggestions on possible solution would be much appreciated - I'm thinking Ill have to write a script to parse the file manually.
Thanks in advance,
Scott

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,
I would like to read from a Text File using SSIS Integration Package.
The file has a fixed number of columns, let's say 3 columns.
There is no row header and each columns length is fixed. There is no delimiter as well.
Here is the sample of the file contents:
John Doe USA
Mary Monroe UK
Andy Archibald Singapore
Here is the hints to read the file contents
123456789
0123456789
0123456789
==============================
John Doe USA
Mary Monroe UK
Andy Archibald Singapore
If you notice, from the 1st column until the 9th column, it's reserved for the first name.
The 10-th column until the 19th column, it's reserved for the last name. Finally the 20-th column until the 29th column is reserved for the Origin Country.
Since there's no delimiter inside the flat file contents, i have difficulty in parsing this text using SSIS Package.
Please let me know if you need any necessary information.
Thanks for all your help.
Regards,
Hadi Teo.

I was trying to using text file source and ole db destination..but since the text file has no columns and have different length per column and per line( it show only one column becasue it all concatnated), I can not map it to destination column..
How can I import it?
Here is the example of text file ( fixed with row delimeter)that i need to import to different columns...

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?

I created a package to import records from a fixed length 700 byte text file to a table in a SQL Database. I used the wizard to set it up and note the byte where each column ends. I need to customize the process, as the name of the text file will change each night, so I want to be able to set the file name from the VB front end app.
I have tried modifying the Datasource property of the DTS connection to the flat file, without success. I have also tried setting a global variable for the datasource property in DTS, and assigning that from VB, similarly without luck.
Do I have to create a custom package in code from VB? If so, how do indicate where each column in the text file ends? If I can customize the existing package, is there a specific reference that I need to set in my project that will let me control the value of the global?
TIA

We are converting an old (circa 2000) VB app that used an Access database to a C#/SQL Server 2005 database. One of the key business processes in this app was to import large quantities of data (200K+ at a time). The format of the text file is fixed length and while we would love to change it we are unable to (the user community would burn us in effigee if not for real). I have been looking at DTS, BCP, and Bulk Insert using format files and, while I think we can get most of the way there I am not sure if I am understanding the format file structure completly. Below is the import specification for one of our files:
FieldName DataType Start Length
AFIID C 1 5
LOCID C 7 15
LOGDATE C 23 11
LOGTIME C 35 4
LOGCODE C 40 4
HEADDIR C 45 3
SLUGVOL C 49 7
UNITS C 57 10
As you can see the each column is separated by a single space so that the second column starts two beyond the length of the first column, etc, etc. Here is an example of the data (the numbers in the first two rows are there to assist counting characters and do not exist in the real import file)
1 2 3 4 5 6

From what I have read about the structure of format files you start with the host file field order number, then the host file data type, then prefix length, then field length, then field terminator, then database column order, then database column name, and final the collation.
This looks like it would work great for delimeted files but in my case there are no delimiters. If I don't include a terminator ("") would the following format file spec import my data correctly?
9.0

Hello All,
Can someone tell me how (in SQL) to convert an integer to a fixed length character filled with leading zeros. For example, I have an integer value of '125'. My user wants to see it displayed as '00000125'. How do I get the zeroes to fill in to a char(8) field when the length of the value differs, ie. '1', '125', '3452', etc.
Thanks in advance,
Terry

I have this doubt and want to be sure if my thinking is correct.
Lets consider 2 tables one with Fixed length columns (char) and other table with Variable length columns (Varchar).
The table with fixed length column will always allocate same size within a Page however, table with variable length column will allocate actual length of data within a page.
I think that updates happening on table with fixed length columns will have more possibility of InPlace updates at least from data length perspective, however updates on table with variable length columns will have more split updates from data length perspective.

An application I developed normally works great, but it seems that when processing a certian record (and none of the others so far), SQL Server throws this error:
"Invalid length parameter passed to the substring function."
Here's the code in question:
orderConnection.Open()
orderReader = orderCommand.ExecuteReader()
setControls(orderReader)
...
Private Sub setControls(ByVal dr As SqlDataReader)
If (dr.Read()) Then '<--*******problem line*******
The SqlDataReader (orderReader) doesn't blow up or anything until I call .Read() (and, as mentioned, this problem only occurs for one order). What could be happening here?

Hi,
I try to use Data Transaction Service (SQL Server 7) to copy information from an Sql Server Table to an text file (fixed field). When I run the process, no problem, the text file is created and a Ok message appears. But when I look in my text file, every time a field was NULL or empty in the source table, the following fields are not aligned !
Somebody knows what the problem ?

I 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?
I need some way of converting the empty string into a null. Has anyone got any ideas for me?
