Header in flat file destination (ssis)
Hi
I am creating a header in the flat file destination which has some hard coded values and record count which will get its value from a variable assisgned to a row count transformation in the package.
There is no problem in hard coded value but when i try to get the value of record count, i always get zero.
This is how i am doing it.
In the flat file destination, when we open flat file destination editor, i hard code the values which i want in the HEADER itself right there in the editor.
For the record count, i go properties of the flat file and select expression. In the expression editor, in property, i am selecting 'HeaderRowDelimiter' and drag that variable in the expression box.
Let me know if there is any suggestion.
Thanks
The value of the rowcount is only known AFTER the Data Flow Task is completely finished... and there header is writen before that.
Here are some examples:

Reorder columns in Flat File Destination
Hi Friend's
Although, I did some google in order to find the solution for reording the columns before exporting to a text file using FLAT FILE DESTINATION, one of the work around which i found is editing the final package xml file and moving the DTS:FlatFileColumn
fields as required.
Is there any other solution in order to avoid this approach as I have some 40 fields to be displayed in text file and manually reordring these fields in xml would be cumbersome.
I need to create text file using FLAT FILE DESTINATION.SSIS Data flow doesn't support dynamic metadata, and any changes in metadata like re-arrange mappings should be done manually. if you want to have columns in a re-arrange design which could be re-mapped dynamically and simply it is better to looks for
another way than data flow task, dynamic t-sql queries can be good alternative.

Dynamic Header Values in Flat File Destination
Hi,
I have to put 'T' or 'P' as part of a header in a flat file destination. The header is sourced via a work table which defines what the header looks like. One of the columns should contain 'T' for test or 'P' for production. When the package is executed in
the test environment, 'T' should appear as part of the header. When the package is executed in the production environment, 'P' should appear as part of the header.
Any ideas on how to achieve this is very much welcome.
Thanks,
AJPackage parameter indicating the environment and a DerivedColumn transform that generates a column with T or P depending on the parameter value.

[Flat File Destination [220]] Error: Failed to write out column name for column "Column 2"
I am using SSIS to extract fixed width data into a flat file destination and I keep getting below error. I have tried almost everything in this forum but still no solution. can anyone help me out to solve this problem.
[Flat File Destination [220]] Error: Failed to write out column name for column "Column 2".
[SSIS.Pipeline] Error: component "Flat File Destination" (220) failed the pre-execute phase and returned error code 0xC0202095
ThanksHi Giss68,
Could you check the Advanced tab of the Flat File Connection Manager to see whether the InputColumnWidth and the OutputColumnWidth properties of the Column2 has the same value? Please refer to the following link about the same topic:
http://stackoverflow.com/questions/10292091/how-do-i-fix-failed-to-write-error-while-exporting-data-to-ragged-right-flat-fil
If it doesn’t work, please post the sample data and the advanced settings of Column2 for further analysis.

Dynamic Column Names in Flat File Destination
Hello,
Inside a Data Flow Task, I have an ADO.Net data source which executes a stored procedure that provides results in 5 columns.
The requirement is to have it connect to a flat file destination, such that the column names is dependent on what data was pulled by the data source. There is a variable indicator which identifies the data that was pulled. For example:
If the indicator is 0, then the columns names will be A,B,C,D,E. Otherwise, if the indicator is 1, then column names will be V,W,X,Y,Z.
Any suggestions will be of great help.
AJIf you only have two variations then use a branched execution (based on precedence constraints) and direct it to one DFT or another based on the result returned by the stored procedure.
Otherwise use .net
code to create one package or another dynamically.
PS: I suggest not to bother using SSIS for such a simplistic scenario.

Flat File Destination Multiple Delimiters
Hi Guys,
This might been an easy one for you. I need to find out if the data from a table can be loaded into a text file with multiple delimiters or not using SSIS? For example, if I have 2 columns of data from a table,
ID Name
100 Mark
I need to load this into a flat file and the output should be like this
100,@Mark
So basically, I need to have 2 delimiters in the flat file destination namely "," and "@". How can this be done.
Thanks in advance.Can't you just fill in two delimiters in the Column Delimiter field of the Flat File Connection Manager (never tried it)?
Alternatives:
-In the source query add a @ to the second column: select column1,
'@' + column2 as column2 from yourTable
-Add a Derived Column with an expression that adds a @ in front of column2: "@" + [column2]

How to split column wise into separate flat files in ssis
IN SSIS...
1.---->I have a sales table country wise regions like (india, usa, srilanka) ....
india usa
srilanka
a b
c
d e
f
so i want output like in
flat file1.txt has india flat file2.txt has usa flat file3.txt has srilanka
a b
c
d e
f
2.----->i dont know how many regions in my table....dynamically split into separate flat files ....
pls help me.....thank uI think what you can do is this
1. Do a query based on UNPIVOT to get the data as rows instead of columns
For that you can use a query like this
IF OBJECT_ID('temp') IS NOT NULL DROP TABLE temp
CREATE TABLE temp
Country varchar(100),
Val decimal(25,5)
DECLARE @CountryList varchar(3000),@SQL varchar(max)
SELECT @CountryList = STUFF((SELECT ',[' + Column_Name + ']' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = '<SalesTableNameHere>' FOR XML PATH('')),1,1,'')
SET @SQL= 'SELECT * FROM <SalesTableNameHere> t UNPIVOT (Val FOR Country IN (' + @CountryList + '))p'
INSERT temp
EXEC (@SQL)
Once this is done you'll get data unpivoted to table
Then you can use a execute sql task with query like above
SELECT DISTINCT Country FROM Temp
Use resultset option as full resultset and store the result to an object variable
Then add a ForEach loop container with ADO enumerator and map to the object variable created above. Have variables inside loop to get inidvidual country values out.
Inside loop place a data flow task. Use a variable to store source query , make EvaluateAsExpression true for it and set Expression as below
"SELECT Val FROM Temp WHERE Country = " + @[User::LoopVariable]
Where LoopVariable is variable created inside loop for getting iterated values
Inside data flow task place a oledb source, choose option as SQL command from variable and map to the above query variable.
Link this to flat file destination create a flat file connection manager. Set a dynamic flat file connection using expression builder. Make it based on a variable and set variable to increment based on loop iteration
The core logic looks similar to this

hi
i am adding new field to my existing package which is char(10).
getting this error:
[Flat File Destination [139]] Error: Data conversion failed. The data conversion for column "MEMBER_ID" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
i right click flat file destination->i only see external and input column over there,
there is no output column.
in flat file connection mamanger ->outputcolumn->its char(10)
what needs to be change here?Hi coool_sweet,
According to your description, you are trying to add a new source column to a flat file in an existing package.
Based on the error message, the issue should be caused by text was truncated when load new column to column "Column1" in Flat File Destination. Because the length of new column data should be more than 10 (with some junk values) in the Source,
while you are trying to convert the column to 10 as the character length.
To fix this issue, we can increase the length of column "Column1" in Flat File Connection Manager. Alternatively, if you still want to convert the new column to a column with length 10, we can right-click the Source component to select “Show Advanced
Editor”, then go to tab 'input and output properties' to expand the output column corresponds to the column "Column1", change TrancationRowDiposition property to RD_IgnoreFailure.
Besides, the issue can also be caused by using some special characters in the new column. We can check the Unicode checkbox on the right hand side of Locale property in Flat File Connection Manager to fix this issue. For more details, please see the following

Flat file Destination VS Raw file Destination ??
Team ,
Can some help me understand few differences and similarities between Flat File Destination and Raw File Destination ? Thanks in advance .
Rajkumar YeluguHi,
Please check these differences :-
Flat File Destination: The Flat File Destination component writes data out to a text file in one of the standard flat-file formats: delimited, fixed width, fixed width with row delimiter.
Raw File Destination: The Raw File Destination is all about raw speed. It is an entirely native format and can be exported and imported more rapidly than any other connection type, in part because the data doesn’t need to pass through a connection
manager.

Compare particular Colums between 2 flat files in SSIS
Hi ,
I want to compare a particular columns bewtween files. if any columns values will mismatched , i need to stop my loading into table.
For example:( Before load into tables)
Flat file 1: Employee
Name Location
M India
C USA
Flat File 2: Location
Location
India.
here USA location is missing .so i need to do this validation before load in to my table. Please sugesst some solution on this.Hi Marimuthu,

You'll need to load the data from the files to a table and then use an SQL query to check them against eachother. From there you can either specify to end the job or only load the matching rows.

How to create a dynamic SSIS package for multiple flat file destinations
Hi,
I have to create a ssis package which has single data flow task and inside that I have 23 source (sql- select * from - statements)- destination (flat files, 23 distinct) connection.
Now for each product I have to create separate SSIS package (i.e. if prod=abc then these read select * from abc_tables and 23 abc_ txt files)
I want to do it dynamically, means only single package and inside that variables will take select * values for each source-dest connection (so i believe 23 variables) and same for destination flat files.
Let me know. :)
ANK HIT - if reply helps, please mark it as ANSWER or helpful postSorry It seems you're contradicting yourself. you say I know my source and dest structure and the you're
asking all I want is to have a dynamic structure
what does that mean?
and reading your next sentence
I want to run a package for 5 products, instead of creating 5 ssis packages with 23 source- dest connection, I would
like to have one with only 23 source- dest connections
What I feel is what you're looking for is to have a looping structure to loop through each of the 5
products.
In that case what you could do is this
1. Create a object variable in SSIS
2. Use a Execute SQL Task to populate the variable with all available products (I think you'll have a master table for that). Set ResultSet property to Full ResultSet and then in ResultSet tab map Object variable to 0 th index
3. use a ForEachLoop container with ADO .NET recordset enumerator and map to object variable. Create a variable of datatype same as that of Product identifier field to get individual values out
4. Inside loop create your data flow task with 23 source destination connection. In the query part use a parameter for product field and map it to the variable containing product value to get only data for the product.

Header at text file (Destination ) in SSIS
How to give the header while fetching from database source to text files destination (Tab Delimiter)
kalsubu,
You may embed it as a part of your query itself if possible.
Had a similar requirement in one of my earlier projects. We obtained the header using a UNION ALL within the query..
declare @tab table (id varchar(10),name varchar(10),[key] varchar(10))
insert @tab select 'a1','temp','k1'
insert @tab select 'a2','temp','k1'
insert @tab select 'a3','temp','k1'
--your actual data
select * from @tab
--Output for text file
select 'H' as val,cast(getdate() as varchar) as date,NULL --Header row
UNION ALL
select 'id','name','key' --Column Names
UNION ALL
select * from @tab --Regular Column Data
(Note that you NEED NOT enable the display column names header checkbox in SSIS)
Thanks,
Jay

SSIS Script Component Conditional Split to Flat File Destination
I have a flat file which needs to be split into multiple flat files based on value in RecordType column.
For example, if (RecordType == 20), then direct all rows to a new text file,
I have around 15 different record types. I have managed to write some C# code for Conditional Split, but
still trying to figure out what is the next step to save these rows to a text file.
I will be grateful if someone please point me to the right direction.
Many Thanks

Ragged right with Flat file in SSIS for last column
When I am importing from Flat file to OLEDB using DATA flow in SSIS,
It has fixed length for each column
but last column had length of 20
So I used for last column as {LF} and input width 0 & output width 20
but facing problem of last column has showing more data in preview so I am missing some some records
May I get any solution
ThanksHi Madhu,
I totally agree with Visakh. If your row delimiter is {CR}{LF}, you need to consider the two placeholders for the delimiter when defining the column length, that is to say you need to set the length of the last column to 22.

Flat File Destination: Broken Rows
I am exporting data to a csv file. One of the columns has values with so mixed characters which end up confusing the system and breaking the rows before the real end of the row. What I mean is; on the flat file a resultant single row can be broken down into
two or more rows as a result of the characters in the offending column. I work for the healthcare industry. Please see the example of what I’m talking about below. This is a real value from one of the rows in my table which I have and this value(amongst many
more under tis column) is causing the affected row to be split into two rows. Where the letters
OE: is coming up as a new row on my flat file. I want all this to be in the same row. My column delimiter is double dagger and my row delimiter is {CR}{LF}
Example value:
Column name: Comments

MpumeleloI think I have managed to get a solution to my problem.
Instead of using csv file I have decided to use text file as my destination flat file format when exporting the data
I have used Tab{t} as my column delimiter
I have left the default system specified {CR}{LF} for row delimiter
On my flat file connection manager, I have gone to the properties and changed
AlwaysCheckForRowDelimiters from True to False.
After a good fight the above worked. No more broken or split rows :).
If anyone has a better approach or suggestion it will be gladly welcome.
Many thanks,
