Writing Text To A Flat File
Jul 11, 2007
I have a Foreach loop which scans a table, and gets names of a bunch of procedures, and then back in the foreach loop, they get executed. Im trying to figure out how I can create a sort of log file to say the name of the procedure that is getting executed currently and the current date time stamp onto a flat file. I havent been able to figure this out yet..anyone know how to do this? I grab the names of the storedprocedures from the table and store it in a variable and use the name from the variable to actually execute the stored procedure.
I guess in essence, the question is how do i directly write lines of 'text' (from say a variable) into a flat file.

Hi
I have a data flow task where I have to write to a flat file. It works fine for me. But the thing is next timeI run the package it must write the data in the OLDEB source to a different copy. Usually the data is overwritten or appended to already existing data. What I want is everytime the package is run the data must be written to a different copy.
Thanks

I'm doing a test package which reads a flat file, makes an adjustment using the derived column task and writes to the same flat file. But, the read locks the flat file, so the write can't access it. Any ideas for a resolution?
Thanks,
Dave

Hi,
I am writing to a flat file. When the data is written to a flat file the columns have to be tilde seperated i.e ~.
What I am doing is I am taking a destintaion text file and having all the columns as tild seperated. Is there any way I can
avoid doing this. That is I should not mention couluns in the text file.
Lastly I want the columns to have a width that is fixed.
How I can do this.
Thanks
Sai

I'm writing to a flat file destination (CSV file) which contains 2 header rows, lets call it Col1 and Col2.
For some reason, the header rows seem to get duplicated in the output - i.e.
Col1,Col2
A,B
Col1,Col2
C,D
Is there any way to resolve this?
I don't want the file to be overwritten everytime since its used for record-keeping purposes.
Thanks

I'm unable to figure out how to write a column header to my flat file destination. My source is a OLE DB SQL query and I need the column names as a header row in my text file destination. This seems easy but the closet I can find is hardcoding the column header row in the header property. Is this the only option?
Thanks

Flat 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.

I have a set of parent/child records that need to be exported to a space delimited Flat File. Each parent record must be followed by 3 child records, each on their own line with different format.
I have a prototype using the Derived Column component that concatinates the various fields of each record into one "wide" text column. This fools SSIS to think that each row has the same format. Then I merge them together using an artificial sort id. But this seems overly tedious and very brittle.
What would be the best approach to writing these records out? I'm hoping there is a better more maintainable method.
Thanks,
Jon

Hi Folks,
I would like to write my table to a delimited file but I seem to have no choice but to use comma as the delimiter. Is there any way I can choose the delimiter ?
Thanks.

Hi,
I am trying to write to a fixed format flat file using Flat File Destination Data Flow Component. I have all required information gathered from more than one sources. But when I tried to format the columns to a big string that will make up one line in the flat file, I could not figure out how to do that. Couple of issues that I am facing are:
How to padd different columns? For example, One interger column has could be 1 to 10 character long in my case. When I convert to string, dont know how to padd the remaining characters i.e. if the value of integer is '1234', it should be written to file as '1234 ' . Which transformation is best in this case, if available?
How to convert T-SQL datetime to a specific date and time format to write in the flate file? I have to write these date formats depending upon one of the parameters passed.
Also, I dont want to put a delimiter at the end of each column, just the new line characters at the end of each record.
Some of the columns has some unwanted characters (like new line characters) how to find them and remove them from the string.
Can we directly write columns to a specific position in the flat file? e.g. col 1 a position 1 and col2 starts at postion 20 etc.
Your co-operation will be appreciated.
Thanks,
Paraclete

I have a variable defined as "Country". Based on the value, the header row printed needs to be different.
I've already created a 'HeaderRow' variable that I'm able to set using a script task. But how can you set the Header text value at run time from the variable? There is no expression defined for the Header with the Flat File Destination object, and when I attempt to reference the HeaderRow variable as the Header text, the variable name is printed as the header.
Another approach I tried was to write the Header Row separately through another data flow task, but the issue here is: what is the input source when all you have is a Country variable?

I have a package that contains three database tables (Header, detail and trailer record) each table is connected via a OLE DB source in SSIS. Each table varies in the amount of colums it holds and niether of the tables have the same field names. I need to transfer all data, from each table, in order, to a flat file destination.

We are using an ADO.NET provider in SSIS to read data from a SQL Server 2000 table that contains DateTime columns to write to a Flat File Destination. When the date values are written to the file they are formatted in TimeStamp to the 10th decimal position; e.g.€œ2006-04-24 12:00:00.123000000€?. Since SQL Server supports values to Timestamp(3), we need to truncate the last seven zeros to put the data in this format €œ2006-04-24 12:00:00.123€? to keep the file as small as possible.
Since we have several hundred DateTime columns in scope for our requirements we are looking for the least logic/effort to accomplish this task. We can do this via Data Conversion and Derived Column transformations to cast the dates and strings but it is very labor intensive. It would be something like singing 99 bottles of beer on the wall eight times in a row with each verse taking 3 minutes each. Yikes.
We have tried casting the DateTime columns to varchar in the SELECT statement but receive this format €œApr 24 2006 12:22PM€?.
Is there a configuration we've missed that forces timestamp(10) with non significant digits?

Hello all,
I was trying to run a test to write a ebcdic file out with a comp - 3 number (testing this for other people) and have run into a problem writing the string out to the flat file destination. I have the following script component:
Code Block
' Microsoft SQL Server Integration Services user script component
' This is your new script component in Microsoft Visual Basic .NET
' ScriptMain is the entrypoint class for script components
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Public Class ScriptMain
Inherits UserComponent
Public Overrides Sub CreateNewOutputRows()
'
' Add rows by calling AddRow method on member variable called "Buffer"
' E.g., MyOutputBuffer.AddRow() if your output was named "My Output"
'
Output0Buffer.AddRow()
Dim myByteArray() As Byte = {&H12, &H34, &H56, &H7F}
Output0Buffer.myByteStream = myByteArray
Output0Buffer.myString = "ABCD"
Output0Buffer.myString2 = "B123"
myByteArray = Nothing
End Sub
End Class
I have added myByteStream as a DT_BYTES length 4, myString as (DT_STR, 4, 37) and myString2 as (DT_STR, 4, 37) to the output 0 buffer.
I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width.
When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following:
Code Block
[Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems.
NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.

I am trying to create a text file from multiple SQL Tables using @BCP_Command. I tried using DTS and SQL but the number of columns in the tables have to be the same size when doing a union. I also not to place a delimeter between each column. I've learned how to use BCP_commands on one file not sure if you can make it work with two or more.

Want to write from a table variable to a text file from a stored procedure.Read about xp_cmdshell bcp etc. but worried because it's supposed to be a security problem and needs to be from a permanent database.Also am getting error "The EXECUTE permission was denied on the object 'xp_cmdshell'..."
1. Is xp_cmdshell a bad idea to use even if I get permissions ?
2. Can a "permanent" table be used in a stored procedure starting out fresh each time with 0 rows rather than use a table variable ?

Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)
{
Console.WriteLine(ex);
}

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, I need to export data from my sql server to a flat text file.
using select I only have the options of delimmited or column aligned, in either case the output file is unicode encoded. I need an ASNI encoded file.
I can create a non Unicode file if I use Import/Export but then the file does not have CR/LF or enf of record mark which I need.
Is there a way to export a flat text file without unicodes and with CR/LF or enf of record mark ?
I was looking into bcp, but I can't seem to find a good sample for this.
thank you

I can do this using import/export wizard, but my output file does not a CR/LF or end of record marker. There is no option to add this. my main reason for using the wizard is because I need to export the file without unicodes, and I can't seam to find any other way. any options?

I'm exporting using a query to a flat .txt file. The problem I'm encountering is when I export the data and then open the .txt file into excel some columns cause line breaks to the next row. The columns that are breaking to a new row are varchar fields where the user has entered text into the field with double quotes ".
When I export, I'm using row delimiter {CR}{LF} column delimiter Comma and text qualifier Double Quote (")
Is there a way to prevent this from happening when I export and open the flat file into Excel?
I tried using replace, but I was getting a syntax error in my query. Here is the query without using replace:
SELECT e.session_date, l.lab_no, i.first_name + ' ' + i.last_name AS Teacher,
tt.name, d.district_name, s.school_name, t.title, a.q1 AS Question1, a.q2 AS Question2,
a.q3 AS Question3, a.q4 AS Question4, a.q5 AS Question5, a.q6 AS Question6, a.q7 AS Question7,
a.q8 AS Question8, a.q9 AS Question9, a.q10 AS Question10
FROM evaluation e
LEFT OUTER JOIN training t ON t.id = e.training
LEFT OUTER JOIN lab l ON l.id = e.lab_no
LEFT OUTER JOIN instructor i ON i.id = e.instructor
LEFT OUTER JOIN trainee tt ON tt.id = e.trainee
LEFT OUTER JOIN district d ON d.id = e.district
LEFT OUTER JOIN school s ON s.id = e.school
LEFT OUTER JOIN answers a ON a.id = e.answers
WHERE session_date >= '20070401' AND session_date < '20070501'
I would need to use the replace on columns a.q7, a.q8, a.q9, and a.q10
I tried using another delimiter...pipes (|) and that didn't work? Maybe I was attempting it incorrectly?
Thanks in advance for any help.

Hi,
I'm wondering if there is any way to get SSIS to notice, in the Flat File Source, that a "Ragged right" text input file has a record that is too short to populate all the specified columns.
I am reading data from a file that is supposed to be fixed length records, but record 193,591 (out of approx. 500,000) is 20 bytes short of the fixed length (60 bytes). So I changed the input to "ragged right" and found that I can thereby continue to read the file, and load the data (after setting the "maximum errors" to a number greater than the initial "1"). (Without this change to "ragged right", every record after the bad one was "out of synch" with the column arrangement -- so they never made it into the database table destination.)
But the "failures" I am now getting are during the Data Conversion step, when I try to convert some columns to integers (from text, in the input stream). And by looking at the data with a "Redirect Row" setting for the Data Conversion step, I am able to see that the Flat File Source is reading "right past the end of the row."
Is there a way to get the Flat File Source to honor the CR-LF record terminator, and decide that some text columns should contain "nothing" (NULL or zero-length strings), rather than the bytes that contain the CR-LF and the initial text from the next record? Can this somehow be noticed as an error condition?

I have a flat text file with lots HTML tags and corresponding valuesÂ
For exampleÂ
<Near_Side> 5563 </Near_Side>
<Top_Down_Code> Xe345 <Top_Down_Code>Â
So, For example I can use the a functionÂ
ALTER function dbo.StripHTML( @text varchar(max) ) returns varchar(max) as
begin
  declare @textXML xml
  declare @result varchar(max)
  set @textXML = REPLACE( @text, '&', '' );
[Code] ...
To which Select dbo.StripHTML('<Near_Side> 5563 </Near_Side>')  ValueÂ
I'll get 5563
However how would you get the values within the tag itself ? E.g.Â
Value NameÂ
5563 Near_side
Xe345 Â Â Â Top_Down_Code
I was thinking along the Charindex but cant seem to get it right.

Unlike SQL Server 2000 DTS, SSIS Flat File Connection Manager Editor does not provide available list of Text qualifier,
i tried
-- ""
-- double quote {"}
-- "
--{"}
but none of them worked....!
My file sample looks like this
"Col1","Col2"
"1234","3456"
"3456","1234"
what qualifier should I use then?

I have made a package that reads a text file into a table.
The data in the file is roughly as follows.
1, "a", "b,c,ddddd", 4, "ee", 0 with the column sizes int, 1, 50, int, 2, int
On all the desktop Bids environments and a SQL 2005 instance on windows server 2000 the package runs fine.
on the 2 Windows server 2003/SQL 2005 machines a truncation error occurs on col 5.
What is happening is on these machines the text qualifier is being ignored and column 5 is reading as ddddd instead of ee!
I figured this out by changing all fields to text and seeing what came out of the other end.
It is very, very strange and I've hit a brick wall.
If Anyone has any ideas throw them in the mixer please?
Cheers,
Steve
