Records From Internal Table Not Output In Order To Flat File
Oct 13, 2006
Hi -
I have a SSIS package that dumps data from an internal table to a flat file output using standard data flow tasks. The entire table is output - no special SQL. Most of the time the records are placed in the output file in the same order as the internal DB table, but occasionally the order appears to be more random. When that happens, the record order in the internal table is correct - it is just the output.
I can find no properties that seem to affect this. I would appreciate any hints and advice that anyone can give me. Has anyone else encountered this same problem?
Thanks in advance,
Jim Sweeney

Hi,
I noticed something strange today. I created a pkg that reads a flat file and writes the rows to a table.
In checking the data in the file against what's in the table, I noticed that the rows were inserted in a different order than they are in the file.
All the rows appear to be in the table correctly, but they're just not in the same order as in the file. I've never seen this before. But I checked very carefully, and this is indeed the case.
Is this normal??
Thanks

I 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.

Hi All,
I have a table A. I need output subset of a table A to a flat file using query, like:
select A.* from A inner join B on... ..... inner join C......where left(A.id, 3) = B.sid.... AND B.num between 100 and 200).
How can I do this in SSIS? Which data flow item I may need?
Thanks

I am new to SSIS and am having trouble with automatically setting up the destination output columns.
I am sure there must be an easy way to do this.
My table (source) has 86 columns in it of varying lenghts.
In my connection magagers, I have created one for the SQL Server (source data) and one for the flat file (destination output).
I have also created an OLE DB source data object and a destination Flat File object and set them up to the respective connection managers.
Finally I have linked the source to the destination.
Now when I look at the source, it shows me all 86 columns.
When I open up destination, there are no columns set up.
Problem: do I have to type in all the columns manually in the connection manager for the Flat File?
I would think there would be some automatic way that it would self-populate the columns over to the flat file destination.

I'm using sqlserver 2000 enterprise edition. I am an oracle dba and we have some tables in sqlserver 2000 that we need to write out to the flat file. I have a procedure in oracle to do this for oracle tables. But, how would I do this in sqlserver 2000. I have 10 columns on this table and I only want 3 columns data to be dumped on the flat file. We are on NT sever 4.0.
Thanks,

What I would LIKE to do is noted in the subject line. What I'm findingis that "edit SQL" appears to only be an option if I am creating atable. If I select "append to" the option to edit SQL shades itself asunavailable.The reason I'd like this is that there is a datum in the flat file thatindicates whether that record should be appended to that table notedabove. There are other ways of dealing with this "problem" but it wouldbe nice to be able to control it using SQL, in the DTS import/exportwizard.If the source of my data is an SQL table, I can generate an SQL queryto specify what fields to import in an append, to check for existingvalues, etc...Is there a way around this? I can reserve a table for data transfers,regularly overwrite it with new data from text file inputs, and use SQLto insert select fields from that transfer table to other databasetables. (From this "transfer" table, data needs to be inserted intofour separate tables in our database).I hope this is clear. If it CAN'T be done this way, it's okay...just alittle ugly with the need to re-create the transfer table.

The following bcp command is present in an NT job I have scheduled each daybcp "EXECUTE DailyProd.dbo.GetIndexComponentStocks_XML '2006-04-05'" queryout "D:TABLESINPUTAPIndexComponentStocks.wrk"
-S(local) -c -T -o"..IndexComponenet_XML_LOG.txt" -e"..IndexComponenet_XML_ERR.txt"
My trouble is that every 2034 characters the output contains a :0D:0A (CR/Linefeed).
Other than that all the output data looks peachy.
Is there some line size setting I am missing (would it be packetsize?)?
Ideally I would just like to not have any CR/LF in my file at all...is there some way to turn it off? I see there are flags to set to change the column and row terminators, but how to turn them OFF???
Thanks much!

I am using a simple input from an SQL data base where I have 4 dates defined as type D. I am writing to a flat file with the fileds defined with any available date format and the output on the flat file comes out as "mm/dd/yy 00:00". I'd like to just have the date portion with no time. The input does not have a time on it so I understand the 00:00 as the value. It seems that I shouldn't have to do any extra work as it is date to date. I've seen the gyrations for a date from the SQL database when it is a character field, but that's not the issue here.
Thanks!

I need to create a number of flat files, all with the same layout and sourced from the the same table, but with different criteria.
The first set of (three) flat files file is created out of a simple Conditional Split transformation: If Source Table row number > 40,000 route to File 3; if row number > 20,000, route to file 2, otherwise route to file 1. This gives me 20,000 rows in files 1 & 2 and the remainder in file 3.
I also want to create a fourth flat file by joining the Source Table with a sample table and selecting only those rows where the Customer numbers match. I'm currently doing this in two stages: An Execute SQL Task performs the join and inserts the selected rows into a Destination table (identical layout to source table), and then a simple data flow moves the rows from the Destination table into the fourth flat file.
My problem is that the order of the columns in the first three flat files is different from the fourth file. I've tried creating the fourth flat file with a single data flow using a Merge Join transformation which didn't work because the tables aren't sorted in the correct sequence, and I couldn't get an OLE DB Command transformation to work either.
I'm not sure why the column order of the 4th file should be different seeing as how its contents are sourced from the same Source table, but is there a cunning way of setting this up so that the columns end up in the same order?

First, a couple of important bits of information. Until last week, I had never touched SISS, and therefore, I know very little about it. I just never had the need to use it...until now. I was able to convert my first 3 flat files to SQL2005 tables by right clicking on "SISS Package" and choosing "SISS Import and Export Wizard". That is the extent of my knowledge! So please, please, please be patient with me and be as descriptive as possible.
I thought I could attach some sample files to this post, but it doesn't look like I can. I'll just paste the information below in two separate code boxes. The first code box is the flat file specifications and the second one is a sample single line flat file similar to what I'm dealing with (the real flat file is over 2 gigs).
My questions are below the sample files.
Code Snippet
Record Length 400

3,16 L=14 Guarantor
17,22 L=6 Guar Account
23,23 L=1 Active Guar
**There can be multiple 05 records, one for each Guarantor on the account**
and the single line flat file...

As you can see, each entry could have any number of records and multiples of some of the record types, with one exception, every entry must have a "01" record and can only have one "01" record. Oh, and each record has a length of 400.
I need to get this information into a SQL 2005 database so I can create a front end for accessing the data. Originally, I wanted one line for each account and have null values listed for entries that don't have a specific record. Now that I've looked at the data again, that doesn't look like a good idea. I think a better way to do it would be to create 5 different tables, one for each record type. However, records 2 through 5 don't have anything I can make a primary key. So here are my questions...
Is it possible to make 5 tables from this one file, one table for each of the record types?
If so, can I copy the Account number in record 01, position 13-19 in each of the subsequent record types (that way I could link the tables as needed)?
Can this be done using the SISS Import and Export Wizard to create the package? If not, I'm going to need some very basic step by step instructions on how to create the package.
Is SISS the best way to do this conversion or is there another program that would be better to use?
I know this is a huge question and I appreciate the help of anyone who boldly decides to help me! Thank you in advance and I welcome anyone's suggestions!

Other than using the -o parameter of ISQL, is there any way to mimic the DBMS_OUTPUT.PUT_FILE capability that exists in ORACLE (also set serveroutput xxx). I have a big need to run both queries and stored procedures and have the output placed in a flat file. This flat file will then be edited and loaded into another SQLServer 7.0 table. Basically,
SP or SQL stmt -> output to flat file -> external manipulation -> SQL table
Thanks in advance.

Hi,
I tried to find some information about this, but surprisingly can't seem to find anything. Seems like it would be a very common scenario.
I need to send the output of a stored procedure to a flat file. First, I created an Execute SQL Task that calls the stored procedure. I selected "full result set."
My first question is, how do I capture the individual column values? For example, under "Result Set", should I create an Object variable, or should I use individual column variables? I've tried both ways, but can't seem to get to the next item, below...
Now, how do I map the variables to the flat file? If I use a data flow task, the flat file has "no available inputs". If I add an OLE DB Source before the flat file destination, there's no place to capture the result set.
Clearly, I am missing something here.
Thanks

I am moving data from a flat file source to a SQL Server table. But I want to add a columm that IS in the destination table, but NOT in the source file. Say the table column name is XXX in destination table, and there will be a global variable called @[User::XXX] that remains constant throughout the package. I would like to put the variable value into the destination column, even though the source file does not contain the field. Is there an easy way to do this?

Hello,
My OLE DB Source is getting data from the following column types:
ID varchar(50), Name varchar(100), Date datetime, Currency char(3), Cost numeric(30,10)
My OLE DB Source outputs my information in the following order when I click Preview:
ID Name Date Currency Cost
When I connect the OLE DB Sorce to a Flat File Destination, it comes out in the wrong order.When I examine the "line" between them (Data Flow Path Editor) I get:
Currency DT_STR Length: 3
ID DT_STR Lenght: 50
Name DT_STR Lenght: 100
Date DT_DBTIMESTAMP
Cost DT_NUMERIC
What is the easiest way for me to change this so the Flat File Destination will output my data in the same order as the OLE DB Source:
ID Name Date Currency Cost
Thank you very much!

I cannot seem to get my flat file to write columns in error when inserting into a SQL table. I have tried a few examples from MS and did not get anything written to my flat file output. I have set the Source Error Output on this flat file and it uses a script task to created the error description and then write it to a Flat File Destination.
I am new to SSIS and have not had any formal training on it. However, I am very familiar with VS.Net/c# and SQL 2000 DTS - I need to get this working ASAP as there are 45 total flat files that need to be processed. Once I have this solved for one, the rest will follow suit.
If more details would help, I can provide them.
Kind Regards,
Ron

Hello friends,
I have the following (simplified):
1. Flat File Source
2. Conditional Split, Case Good = !ISNULL(KEY) Case Error = ISNULL(KEY)
3. Case Good -> Writes to Good Flat File (with timestamp in the title)
4. Case Error -> Writes to Error Flat File (with timestamp in the title)
Most job runs have no errors but the error file is created as a zero byte file anyway. If there are no error records I don't want the error file created. How might I accomplish this?
Thanks

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,
Kul

Hello!
I want to make a very simple package: Export all rows in a table to a flat file.
This package I can create pretty much by only using the wizards.
Now to my problems:
1) I need the output to have this format:
H20070920161522
DS3 Plastpall trippelkrage 40 1
E00000000003
H is a header post, in this case with date and time following.
D is a details post, that is all the rows that was exported.
E is and end post, containing only the number of rows in the file, including H and E posts.
2) I need to set the file name dynamically, preferably using date and time to name the file.
I´ve done this very same thing in T-SQL, like so:
Code Snippet
USE AVK
GO
SET TRANSACTION ISOLATION LEVEL SNAPSHOT;
GO
SELECT *
FROM tempProducts
GO
CREATE VIEW EXPORT_ORDERS
AS
SELECT 1 AS ROW_ORDER, 'H' + REPLACE(CONVERT(char(8), GETDATE(), 112) + CONVERT(char(8), GETDATE(), 108), ':', '') AS Data_Line
UNION ALL
SELECT 2 AS ROW_ORDER, 'D' + COALESCE (CONVERT(char(10), LBTyp), '') + COALESCE (CONVERT(char(50), Description), '') + COALESCE (CONVERT(char(5),
Volume), '') AS Data_Line
FROM dbo.tempProducts
UNION ALL
SELECT 3 AS ROW_ORDER, 'E' + RIGHT('0000000000' + RTRIM(CONVERT(char(13), COUNT(*) + 2)), 11) AS Data_Line
FROM dbo.tempProducts AS tempProducts_1
GO
IF @@ROWCOUNT > 0
BEGIN
BEGIN TRANSACTION
SELECT *
FROM tempProducts
DECLARE @date char(8)
DECLARE @time char(8)
DECLARE @sql VARCHAR(150)
SELECT @date = CONVERT(char(8), getdate(),112)
SELECT @time = CONVERT(char(8), getdate(),108)
SELECT @time = REPLACE(@time,':','')
DECLARE @dt char(14)
SELECT @dt = @date + '_' + @time
SELECT @sql = 'bcp "SELECT Data_Line FROM avk..EXPORT_ORDERS ORDER BY ROW_ORDER" queryout "c:AVK_' + @dt + '.txt" -c -t -U sa -P dalla'
EXEC master..xp_cmdshell @sql
--WAITFOR DELAY '0:00:10';
DELETE
FROM tempProducts
COMMIT TRANSACTION
END
DROP VIEW EXPORT_ORDERS
GO
But I´m sure it can be done in SSIS aswell, giving me some nice options for i.e. error handling aswell.
Pointers please

Hi All,
I have a simple SSIS package that runs a query on the db and outputs a fixed width flat file. I have all my column widths defined and in the connection manager i can preview the output. Everything looks great. All the fields fall where they should and each record is on it's own line.
When i run the SSIS program and then go open my text file with a text editor the ouput is all on the same line. I have tried changing my file format from fixed width to ragging right and adding a row delimiter but that doesn't work either. I feel like i'm missing something small here. It could even be an issue w/ my text editor (although i've tried to open the text file in multiple editors). In the flat file connection manager I have my file defined to be 187 characters long, So figure every 187 characters it should output a new line (it should add the carraige return right?).
Has anyone encountered an issue like this?
Any help would be much appreciated.

I have a flat with few columns
FirstName, lastName, Address
f1,l1,a1
f2,l2,a2
I build my SSIS package based on the above file.But now i receive files with different columns order let say
lastName,FirstNamr,Address
l1,f1,a1
L2,f2,a2
or
Address,FirstName,LastName
a1,f1,l1
a2,f2,l2
every time i receive multiple files in different order and i have to remap all my mappings. These are just a few columns and i have like 20 columns and the order can potentially change any time. so every time i have build new packages remap them etc.
through normal c# code it pretty easy. I tried to add script here but the script also needs a source and mapping so there is also a mapping issue. Is there a better way to do this.

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.

Hello,
I am making my first attempt at creating a script for a Script Task. The script needs to do the following;
1. find the length of each record in a single fixed width flat file
-file location; C:LearningSettlementDataTestSC15_CopiesSingleFile
-file name; CDNSC.CDNSC.SC0015.111062006 (no file extension)
2. if a record is found that is longer than 384 characters;
a. copy the record out to a text file
-location;C:LearningSettlementDataTestSC15_CopiesErrantRecords
-file name; ErrantRecords.txt
b. delete record from the flat file where the record length is > 384.
If I can get this to work on a single file, I want to implement it with multiple files. I would imagine that using a ForEachLoop container with the script task 'inside' would be the way to go for multiple files. I have a connection manager set up for the single file and a MultiFlatFile connection manager set up for the whole collection of files. All of the files have the same schema. I don't know if the connection managers are going to be useful to me with what I'm trying to do, but I have them set up.
If you have some input on where I can find resources on how to do this, or have some code to pass along, please share.
Thank you for your help!

Hello,
I am attempting to import a fixed width flat file into a SQL Server table. When I import the file, 704 records don't make it into the table. I know this because if I do the import with MS Access 2003 into an Access table, all of the records from the flat file make it into the table. The flat files have a .txt extension.
The only possible problem that I can see is that some of the rows in the flat file do not contain the full set of characters. When I do the import into SQL Server and create a table on the fly, I still end up 704 records short. There are no error messages during or after the import.
I suppose I could isolate some of the missing records, put them into a different file and try to import them to see what would happen. Other than that, how do I begin to troubleshoot this problem? Are there known issues where records can be dropped from a fixed width file?
Thank you for your help!

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
