Derived Column Transform (flat File Blanks To 0)
Nov 30, 2006
Hi,
Is it possible using derived column transform to change all blank values in a flat file to say a "0"
Basically convert "" to "0"
Thanks for any help,

Writing Into The FLAT FILE When Derived Column Fails
Aug 30, 2007Flat file is the source for to load the data into a table. I am using "Derived Column Component" for the data validation.
"Derived Column Component" Fails then i am writing/redirecting the records into the Flat File using "Flat File Destination" component.
It works fine except the following the issue.
Issue:
The derived columun value (that cause an error) is not get inserted into the Flat File
Scenario:
the data comes as "000000" and tring to convert to date format
(DT_DATE)("20" + RIGHT(Check_Date,2) + "/" + SUBSTRING(Check_Date,1,LEN(Check_Date) - 4) + "/" + SUBSTRING(Check_Date,LEN(Check_Date) - 3,2))
The above expression is working fine, except the data 000000 not passed into the Flat File Destination.
Pls advise. Thank you.
Adding Implied Decimal Without A Derived Column From Flat File Datasource
Apr 18, 2007We are importing Flat file data from our Mainframe system. We have a lot of money amounts coming in, but the mainframe does not store the decimals in the flat file. So for example a row in the file might look like this:
+0000007894-0000000563
Where the first value is $78.94 and the second value is -$5.63
Is there anyway to have the Flat file connection manager put in the decimal place for me, or do i have to create derived columns for each column and divide it by 100? There like 50-100 columns per file, so i'm looking for a better, quicker way.
Thanks in advance.

Conditional IF In A Derived Column Transform
Apr 12, 2006HI, I was wondering if there is a possibility to use a confitional if like this:
IF(ISNULL(mycolumn value, "new value if null", mycolumnvalue)
into a derived column transform to infer a value to a null column value. I do know I can do it using a script component by it would be simpler to do by using an expression.
Thank you,

Need Alternative To PATINDEX In Derived Column Transform
Oct 30, 2007Hello,
I understand that it is not possible to use PATINDEX in a Derived Column transform. I'm trying to eliminate leading zeros from a column where the string is always 14 characters long, but the first non zero character could occur any number of characters from the left of the string. The following achieves what I need:
substring([Account No w/0s], patindex('%[^0]%', [Account No w/0s]), 14) AS ExtractedAcctNo
Does anyone happen to know how I might express this differently in a Derived Column transform? Should I consider a calling a function through an OLE DB Command transform on each row instead? Maybe I should have a SQL Task that runs an UPDATE statement against the column.
Thank you for your help!

Extending Derived Column Transform With Custom Function Library
Feb 16, 2007When data is imported from our legacy system, the same functions need to be applied to several columns on different tables. I want to build a kind of "Function Library", so that the functions I define can be re-used for columns in several packages.
The "Derived Column" transform seems ideal, if only I could add my list of user-defined functions to it. Basically I want to inherit from it, and add my own list of functions for the users to select.
Is this possible ?
What other approaches could I take to building about 30 re-usable functions?

Ho Do I Get The Details From A DTS Transform Data Task Into An SSIS Derived Column Transformation?
Mar 7, 2008i have too many DTS packages to migrate to SSIS, and while examining a DTS package in BIDS (converted with the migration utility) i tried to edit the resulting migrated package, which opened the DTS interface with the two connection icons joined by the big fat arrow with a gear on it...not exactly what i had in mind, iow, it looks like SSIS on the outside, but its still DTS on the inside.
So I stripped out a series of components from a more complex package hoping that simplifying it would reveal the contents of old DTS Transformations tab at least partially set up in a Derived Column transformation.
Can i get there from here, or must i recreate every stinking definition in a derived column manually from the ground up?
thanks very much for your help
REPLACE In Derived Column Transform Causing Repeat Data In Rows That Should Be Blank
Jul 25, 2006W2k3 server, SQL 2005.
@@version = Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86)
Standard Edition on Windows NT 5.2
(Build 3790: Service Pack 1)
I have my first SSIS package almost working, but I'm having an odd problem and can't find any information to help resolve it.
I'm importing from a flat file (csv) to an existing table (append). I've got a Derived Column transformation in the middle to do some data cleanup. It's all working except for one little problem...
One of the transformations is 'REPLACE([Column 3],"^","; ")', output to a new column. (The input file has a field that uses carets as delimiters between an unknown number of items; I'm changing that to semicolons for easier reading.) Not all rows have data in this column, some will have one item, some will have multiple items.
The REPLACE works except that it fills in repeated data for all the blank rows.
Example:
Incoming data is:
1 Smith,Jane^Jones,Jane
2 Brown,John
3
4 Adams,James^Adams,Jim
5
6 White,Debra
Data inserted into the table is:
1 Smith,Jane; Jones,Jane
2 Brown,John
3 Brown,John
4 Adams,James; Adams,Jim
5 Adams,James; Adams,Jim
6 White,Debra
I've tried to use a Conditional to skip the empty rows, but I can't get that working at all (get syntax errors no matter what I put in).
Any suggestions on how to fix this would be most appreciated!
Thank you.
Transform Header And Detail Flat File Into One Table
Sep 13, 2007I have a flat file with header and detail information, it is actually employee punch card data. I need to parse the header line which contains the Employee ID and don't save it to a table just save the value. Then with the detail line, parse the different data elements and save them along with the employee ID to one table. Then continue until the next header line is read.
The file looks something like this:
FINNEY,RONNIE 0001005420
Mon 09/03 700a HOL 8.00
Tue 09/04 630a*E 326p 8.50 8.50

Thu 09/06 554a*E 3.50 21.60
So I think I need a data flow transformation object that let's me save the Employee ID into a variable available when the next record is read. What type of transformation would be best?
Flat File Connection Manager Throws Error When A Column Gets Added To The Flat File
Dec 27, 2006Hi,
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?
Output Column Width Not Refected In The Flat File That Is Created Using A Flat File Destination?
May 11, 2006I 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.

Unable To Edit Pre-defined Flat File Connection Manager Properties In The Flat File Destination Editor
Aug 24, 2007Hi,
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.
Did someone else faced this issue?
Thanks,

BULK INSERT Flat File With Only One Column
Jan 30, 2004Hi,
I have a text file with a single column that i need to bulk insert into a table with 2 colums - an ID (with identity turned on) and col2
my text file looks like:
row1
row2
row3
...
row10
so my bulk insert i have like this:
BULK INSERT test FROM 'd: estBig.txt'
WITH (
DATAFILETYPE = 'char',
FIELDTERMINATOR = ',',
ROWTERMINATOR = '
'
)
but i get the error:
Server: Msg 4866, Level 17, State 66, Line 1
Bulk Insert fails. Column is too long in the data file for row 1, column 1. Make sure the field terminator and row terminator are specified correctly.
However, as you can see from the text file, there is only one column, so i dont have any field terminators.
Any ideas how to make this work?
Thanks.
SSIS Flat File To DB Column Mappings
Oct 2, 2007hi -
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?
Insert From Flat File Where Column 1 Not In Table
Aug 7, 2007Hi Guys,
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.
thanks for your help

Binary Column Or Flat File Best Practices?
Jul 17, 2007I have a design oriented question for a system I am developing. Because of various business concerns and issues we have been moving towards as desing that brings files into the SQL 2005 system as binary columns in a database. These files will then be processed at a later time using SSIS into relation model tables.
Normally I would just have the process be files are placed on a FTP location (or other drive path) and a location is stored in the database versus the storing of them as binary rows in the database. Then later the SSIS package runs using the path information for the conneciton manager.
Based on the proposed binary design I have two questions.
1. Can anyone speak to the advantages, disadvantages, issues they have had, etc to the binary storage method?
2. Can anyone make a suggestion on how they would handle the pulling of the file out of SQL when the file is ready to process? Do you stream it to a file and rebuild it on the physical disk, to then just import it with a connection manager for the flat file structure.... or can you stream it directly into a conneciton manager that reads it like a flat file and parses the file without ever going to disk? Any information on suggested implementations would be helpful.
Thanks.
Set The Flat File Column Delimiter Programatically
Jan 31, 2007hi guys,
i am working on a project witch involves creating packages on-the-fly to import data from txt/csv/xls files according to some definitions on the database.
so far, i have been doing fine.
now we are planning the ASP.net page that enables the customer to define the input file format that will be imported to the system. we want it to have the same listBox as the FlatFileConnectionManager Editor has to define some properties, such as - column delimeiter.
the code to set the column delimiter looks like this:
SSISRunTime.IDTSConnectionManagerFlatFile90 myFilecn = null;
myFilecn = (SSISRunTime.IDTSConnectionManagerFlatFile90)package.Connections["InputFileConnection"].InnerObject;
DtsConvert.ToConnectionManager90(package.Connections["InputFileConnection"]);
SSISRunTime.IDTSConnectionManagerFlatFileColumn90 col
col = myFilecn.Columns.Add(); //.....
string colDelimiter ="|" ; // it actually gets the data from the database... but it is the same thing
col.ColumnDelimiter = colDelimiter;
when we deal with the simple characters- "," , ";" , "|" ... we have no problems with setting the delimiter. but how can i set the delimiter to Tab? or {CR} ? {LF}?
i tried to look at the dtsx- XML , and i see that the column delimiter that is defined when i choose Tab is: _x007C_, but when i try to do something like this:
col.ColumnDelimiter = "_x007C_" ;
it doesn't work. the same happens when I try "{t}" or "Tab".
how do i solve this problem, and enable the user to select Tab as a column delimiter?
Thanks!
Flat File Conn Mgr Column Limit??
Oct 17, 2007Hi,
I have a flat file with hundreds of columns.
I set up a flat file conn mgr with the following settings:
format: delimited
text qualifier: "
header row delimiter: {LF}
row delimiter: {CR}{LF}
column delimiter: comma
Now, here's the problem. In the preview screen, it shows only up to column 518 correctly. In column 519, it shows the remaining hundreds of columns all glommed together as one big string, like: "data", 123, 10/17/2007, "more data", etc
Anyways, I am wondering what to do about this?
When I attempt to run the data flow I get this error:
[Flat File Source [1]] Error: The column delimiter for column "Column 519" was not found.
However, the good news is that I only need the first 9 columns of the file. Some preprocessing in order, maybe?
Thanks!
Adding New Column To Flat File Source Connection
Feb 1, 2007What is the best way to deal with a flat file source when you need to add a new column? This happens constantly in our Data Warehouse, another field gets added to one of the files to be imported, as users want more data items. When I originally set the file up in Connection Managers, I used Suggest File Types, and then many adjustments made to data types and lengths on the Advanced Tab because Suggest File Types goofs a lot even if you say to use 1000 rows. I have been using the Advanced Tab revisions to minimize the Derived Column entries. The file is importing nightly. Now I have new fields added to this file, and when I open the Connection Manager for the file, it does not recognize the new columns in the file unless I click Reset Fields. If I click Reset Fields, it wipes out all the Advanced Tab revisions! If I don't click Reset Fields, it doesn't seem to recognize that the new fields are in the file?
Is it a waste of time to make Advanced Tab type and length changes? Is it a better strategy to just use Suggest Types, and not change anything, and take whatever you get and set up more Derived Column entries? How did the designers intend for file changes to be handled?
Or is there an easy way to add new fields to this import that I am overlooking? I am finding it MUCH more laborious to set up or to modify a file load in SSIS than in DTS. In DTS, I just Edit the transformation, and add the field to the Source and Destination lists, and I'm good to go. My boss isn't understanding why a "better" version is taking so much more work!
thanks,
Holly
How To Import From Flat File And Update DateTime Column?
Jul 30, 2007I have a a flat file that consists of 2 Columns of data that need to overwrite an existing Table that has 3 Columns of data. The Import fails because the 3rd column on the table is a Date stamp column with the Data Type of "smalldatetime" and does not allow Null data. If I were to delete this 3rd column from the table the import works great but I lose the DateTime column. How can I use the Import Wizard to import the first 2 columns from a text file and update the 3rd column with the date and time? The wizard does not seem to let me update a column unless the data for this column comes from the flat file. Please assist, thanx.
View 6 Replies View RelatedFlat File Source - How To Configure An Appropriate Column Delimiter?
Feb 19, 2008Good day everyone,
I have a package that reads data from a CSV file, transforms it and finally loads it in a destination DB table.
My current problem lies in the parsing of the input flat file. I shall illustrate it using a small example.
Source File:
P;Product-1;Short Description for product 1
P;Product-2;Short Description for product 2
Problem:
I configured the flat file connection manager to use semicolon as the column separator. But then I have received some sample flat files where I found that the semicolon might be sometimes used as content of a column data.
Possible Solutions:
I have thought about 3 different solution and I would like to get your feedback and recommendations about them.
Alternative 1:
Use a complex column delimiter, which wouldn't be used in the data.
Example:
P#~#Product-1#~#Short Description for product 1
P#~#Product-2#~#Short Description for product 2
Question 1:
- Is it possible to define such a customized column delimiter for the Flat File Connection Manager?
- If yes, how can I do this?
Alternative 2:
Use double quotes around the data, which the Flat File Source Adapter must somehow recognize and trim before pushing the data down the Data Flow.
Example:
"P";"Product-1";"Short Description for product 1"
"P";"Product-2";"Short Description for product 2"
Question 2:
- Is it possible to configure the Flat File Source Adapter to work as described?
- If yes, how can I do this?
Alternative 3:
Use a Script Component and write the needed code for parsing the Flat File.
Question 3:
- Do you have further suggestions/ideas for solving this parsing problem?
Thanks in advance and my regards,
Samar
How To Store Column's Value From A Flat File Into A Package Variable?
Oct 7, 2007I 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?
Thanks!

Flat File Source Column Parsing Error
May 12, 2006Hello All,
I have come across this issue with the Flat File Source when the delimiter is set to a comma.
"""KAILUA KONA,HI""","CA",
In the data snippet above and with the setting of using a comma as a column delimiter
and a " as the text qualifer.
the data will be parsed in this fashion:
"""KAILUA as a column:
HI""" as a column
CA as column
when it should be
"KAILUA,HI" as a column
CA as column.
Is there a way to let the Flat File Source to let it know not to parse the data in multiple quotes ?
Thank you

Populate Column That Contains Some Blanks With A Defined Value
Jan 8, 2015I am looking for a query which will populate one of my columns that contains some blanks with a defined value based on a value in another column
For example in the below table I would like the blanks in serial number to be populated with "SN09"
Product_NameSerial_Number
PRODUCT1
PRODUCT1
PRODUCT2SN10
PRODUCT3SN11
PRODUCT3SN11
PRODUCT1
So the query I am looking for would basically add some values to the results where they meet the right criteria.
I am running the query through a view so I dont actually want to add the values to the physical tables only to the view of the results if you understand what I mean?
Extract Column Data From Flat File Error Output
Dec 10, 2007Hi Friend,
I am stuck with a problem and need your help. As we know, all columns that go to error flow of flat file source connection are displayed as a single column e.g. FlatFileSourceErrorOutputColumn, but my requirement is to extract the first column value from this FlatFileSourceErrorOutputColumn, my data is dilimeted by "|" pipe operator. I have created a script component to deal with this. However if we take FlatFileSourceErrorOutputColumn column as input column in script component, it comes as BLOB data. I wrote below code in transformation script component to extract BLOB data from column in string form and then do a Left function search to take first column out.
When I am running this script component I am getting '??????????' question marks as a result in Row.Pname.
Can anyone please help me understand if I am doing anything wrong in this script or suggest a better way to take the data out?
I appreciate your help.
