I want to extract data from a table (based on a query) to a flat file.
So I have an OLE DB Source (data access mode SQL command) and then a flat file destination. The extract works finem except it extracts all table rows as one line in the file - whereas i want a separate line per DB record - what am I missing?
Thanks for any help!

Hi 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.
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
'
'
Dim Error_Data As String
Dim Column_1 As String
Dim Len As Integer
Dim Buffer As Byte()
Buffer = Row.FlatFileSourceErrorOutputColumn.GetBlobData(0, CInt(Row.FlatFileSourceErrorOutputColumn.Length))
Error_Data = System.Text.Encoding.Unicode.GetString(Buffer)
Len = Error_Data.IndexOf("|")
Column_1 = Left(Error_Data, Len - 1)
Row.Pname = Column_1
End Sub
Thanks,

Hi all,
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
Any suggestion or help would be welcome.

I have a flat file that has over 50,000 records. When I import that file into my table I'm only able to extract 26,612 rows.
I'm using a Flat File connection manager
The format for this connection is Ragged Right
There are about 25 columns, or so
My Data Flow Source is a Flat File (Imagine that!)
I appreciate any ideas that you may have.
Thanks!!
Hi,
I have a dataflow task which has 3 oledb source objects connected to each data conversion object and these are connected to a union all and finally to a flat file destination.
The purpose of this one is to extract data and pump them to the flat file.
If i run this in production during the time users are doing transactional processes (typical, add, edit delete), will it have an impact?

Hi,
I am trying to impliment a SSIS package where data source is a Flat file(.csv) file and destination is a sql server database.
The problem is my data source a flat file which consists of thousands of rows which are manually entered, so there is always a chance that in some rows they may miss a column value while entering data which results in an error.
Example: My flat file has headers like Sln, Name, Age, Designation. While entering data they may miss age and type it as 1,aaa,Consultant,,
Using SSIS package i want to track all row number in the flat file where data is entered wrongly so that i can correct only that row instead of checking all rows each time when my SSIS package throughs an error. I want to get all the row numbers in a sql server database which are wrongly entered.
Any suggestions are sincerly apriciated.
Thanks in advance

[Flat File Destination [46500]] Error: Data conversion failed. The data conversion for column "Column 0" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page." What does this error mean exactly?
I am taking columns from a flat file source. Then I am adding some new columns then rewriting the file to a ragged file format with fixed column values. I've taken the Destination component off and it works fine. So I know it could be the destination component but what could it be? Any ideas?
Each day I receive a file with a different name. For example, the name is filename_mmddyyyy.txt where filename_ stays constant and mmddyyyy is the date of the file. The file is always in the same format.
I want to build an SSIS where I pass it this file name. I can write a script to generate the correct file name. How do I build the SSIS so it can accept the input parameter and find the correct file to process?
Thanks
It seems I can do the type conversion in two place:
1. The advanced editor for flat file source => Input and output roperties. And I can set the output columns data type properties there.
2. Using a Data conversion box in Data flow transformation.
Any difference between these two? Which one should be used?
I'm new to SSIS and have run into a problem I'm hoping someone can help me with.
Basically, I have a flat file that looks something like:
ID,Type,Description,Results
1,Test1,This is a test,5
2,Test1,This is also a 1 test,7
3,Test1,This is also a 1 test,13
4,Test2,This is a second test,14
5,Test2,This is also a second test,18
I'm trying to normalize the data by extracting out individual rows that have the same "Type" column value. So what I want is to extract each unique type and description into a separate table. This would give me two new rows, one for a type of Test1, and one for a type of Test2, with the descriptions. Does this make sense? Then I could relate the individual results to these test types. In my scenario, I don't care which description is used; I just want to take the first description that shows up with the associated "Type."
Does anyone have any idea of how I could go about doing this? I could pull out all unique "Types" from the rows with the Aggregate transformation, but I'm trying to figure out how to get the description that goes along with it.
Thanks,
Brian
I writing the data from sql table to flat file destination. I want to insert the record count in the first line of the destination file.
Record count must preceed 00.EX . Writing 4500 records from database should show 004500 in the first line of flat file.
I have an execute task to store the count in a variable now.

View 1 Replies View RelatedI'm having a problem using the Flat File Source while using the underlying .Net classes to execute SSIS Packages. The issue is that for some reason when I load a flat file it Empty's out columns randomly. Its happening in the Flat File Source Task. By random I mean that most of the times all the data gets loaded but sometimes it doesnt and it empty's out column data. Interestingly enough this is random and even the emptying out of columns isnt a complete empty, its more like a 90% emtpying. Now you'll ask that is the file different everytime and the answer is NO. Its the same file everytime. If I run the same file everytime for 10 times it would empty out various columns maybe 1 of those times. This doesnt seem to be a problem while working with dtexec or the Package Executor utility. Need Help!!

View 4 Replies View RelatedI am working to archive some old data from a data warehouse using SQL server and SSIS. The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required. Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.
Hi Guys,
I
have a flat file which is loaded into the database on a daily basis.
The file contains rows of strings which I load into a table,
specifically to a column of length 8000.
The string has a length of 690, but the format is like 'xxxxxx xx xx..'
and so on, where 'xxxx' represents data. So there are spaces, etc present in the middle.
Previously
I used SQL 2000 DTS to load the files in, and it was just a Column
Transformation with the Col001 from the text file loading straight to
my table column. After the load, if I select len(col) it gives me 750
for all rows.
Once I started to migrate this to SSIS, I
allocated the Control Flow Task and specified the flat file source and
the oledb destination, and gave the output column a type of String and
output column width of 8000. But when I run the data flow task it
copies only 181 or 231 characters out of the 750 required.
I feel it stops where it finds the SPACES and skips the rest.
I
specified row delimiters or CR, and LF. I checked the file under
UltraEdit and there were no special characters in the file that would
cause the problem.
Any suggestions how I can get it to load the full data?
Thanks
I have requirement like to develop dynamic package for inserting data from flat file to table.
Find below points for more clarification :--
1) if I changed the flat file values and name in source variable AND the table name should be also changed based on variable value .
2) it should dynamically mapped with column values with source file as we have to insert data in target table.
See below diagram for more clarification.

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)
{

}

public const string Property_SourceConnection = "SourceConnection";

_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)

Hello,
how can I connect to a cube (on a SQL 2005 server) and get (fact) data to process with SSIS? I looked at the toolbox but I see no applicable tool. It would be fine if somebody can provide a link to an article or example.
Thanks in advanced!

I am trying to import a flat file into SQL Server 2005 using SSIS. I have never used it before and I am getting confused by the error I am receiving.
I have a link to a flat file, that gets sent through a Derived Column flow where dates in YYYYMMDD are changed to MM/DD/YYYY format. Then the string MM/DD/YYYY is converted to a date in a Data Conversion flow. And finally the data is put into a SQL Server table (currently with no rows).
The problem I am having is with a text field with the email address in it. The error I am getting is:
[Import Allstate Auto Club [1]] Error: Data conversion failed. The data conversion for column "email_source" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
The problem is I can't see where in the flow the problem is. The field length is 20 wherever I look and the codepage is 1252 wherever I look. Does anyone have an insight? Keep in mind, I have never used SSIS before and I consider myself an amateur with SQL Server. It could easily be a data type conflict or something easy. Any help will be appreciated.
Hi,

Ok everybody. I am new to sql. I have ms sql staging database that pulls data from mysql database. Then once a day I run a ssis package that moves the data to a live database and also creates a flat file that is posted to a ftp site then truncates the table. One problem I am running into is if the mssql staging database has no records the flat file is still created. How do I stop it?

I have a fixed width flat file I'm trying to insert into an SQL 2005 table using SSIS -- it's a recurring task. One of the columns in the flat file has to go to a column of type Numeric. No matter what I try : a data conversion, defining the field as DT_NUMERIC in the connection,... I always get "The conversion returned status value 2 and status text :The value could not be converted because of a potential loss of data". It is driving me bonkers, up to the point that I find myself wishing for the 'good old' DTS days of SQL 2000. And I dread to think what will happen when I try to port some serious, much more complex DTS packages on my SQL 2000 to SQL 2005.
The data in question represents longitudes and latitudes so quite often there is a leading white space in the data : ex. : " 95.15". Surely that cannot be the cause ?
I've spent hours doing the RTFM-thing and searching the newsgroups, fora...you name it. Apart from ending up running in circles in the MS documentation, the only thing I've really learned so far is that I'm aparently not the only one driven to dispair by the new SSIS thing.
I can think of a number of ways to hack my way around this thing, but that's not the kind of 'progress' I had in mind when I started the move to SQL 2005.
Intelligent suggestions would be most welcome.
