I created a SSIS to export to a flat file (from a SQL command : a stored proc).
I don't wan't my SSIS to create an empty file if there is no data.
How can I achieve this ?

Trying to figure out the best method of reading in a number of flat files, all with different number of columns and data types and outputting them to a database.
Here's the problem: They are EBCDIC encoded and some of the columns are packed decimal. I've set up one package that takes the flat file, unpacks the decimal (Using UnpackDecimal component) and then sending the rest through a second component to go from EBCDIC -> ASCII.
What I need is a way to do this for every flat file based on the schema for that flat file. One current solution is to write a script/app to create the .dtsx XML file and then execute that for each flat file. It appears like this may be possible, but I haven't gotten far enough to know for sure. So my questions are this:
1) Is there an easier way to do this (ie somehow feed the schema to the package and use it to dynamically set up the column makers and determine which columns get fed to the unpack decimal component.
2) If there isn't a better way, will dynamically creating the .dtsx XML file based on the necessary input/output columns for each flat file work? If so, what is a good source of information on this (information about how the .dtsx XML file is set up, what needs to be changed/what doesn't, etc).
Thanks,

Here's a really annoying problem. Let's say you have a text file with 2 million rows.Delimiters all look good and rows are previewed well but the file has a missing row at say lin 1234567 - way deep in the file. When SSIS encounters the blank row, an error is raised and processing on the file STOPS! I verified this in by checking the SSIS log and have even developed an error routine to notify me via email when the error occurs (really cool if I do say so myself ). The main problem still remains - how to resume processing from the point of failure in the file? Any help is appreciated. Thanks.

Hi,
In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.
The table may contain column that are NULLable BUT there is NO DEFAULT for them.
If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?
I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:
1- set the DEFAULT(NULL) for EVERY column that needs this behaviour
2-set up some Derived Column option in the package to return NULL if the value is missing.
Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.
Thanks

I am attempting to get this script provided by Microsoft to work to no avail. Specifically, when I set the variable FFNonDataRows to 1 (in order to accommodate for the header row), the variable is not being set to False as expected. I don't know enough about C# to understand why this script isn't working. How to get this script to work in this manner?

I am using a Foreach loop container to go thru all the files downloaded from the ftp site and I am assigning the file name of each file to a variable at the foreach loop level called filename. In the dataflow task inside the foreach loop container, I have a source script component that uses a flat file connection. The connection string of the flat file connection is set to the filename variable declared at the foreach loop level. However the script component has a error System.ArgumentException: Empty pathname is not legal.
Please let me know how to correct this? The connectionString property of the flat file connection is set to the complete filename including the path. Does a script component need to have a flat file name specified in the flat file connection that it is using? I need to have a script source component as the flat file I am reading from is not in any of the standard formats.
The flat file connection manager's connection string property is blanked out the moment I specify an Expression for the connection string. Is this a defect or is it expected behavior.
Any inputs appreciated.

I'm looking for a manner to create by code a flat file connection manager and a flat file destination.Greets
View 3 Replies View RelatedI have a table that holds in each record an image (varbinary(max) actually), a text reference for the image and a MIME type for the image. I need to read this table and for each record that has been created since the last run, I need to create a file with the image as the content, the mime type as the file extension and the text reference as the file name. There will be one file created per record found by the data flow source.
I was assuming that I could use the flat file destination and manipulate the file naming using the contents of each record in the flow but am completely stumped on how to achieve this.
Does anyone have any ideas?

I'm using SSIS to import seven flat files (each containing a different record type) into a staging database. This part was easy.
Now I need to export the records from all seven tables into a single flat file structured in a nested hierarchy using common keys. (This format is required by the vendor for loading data into a new system).
I could use some ideas on the data transformations needed to combine all seven record types into an hierarchical record set which can then be written to my Flat File Destination. I'm currently looking at an article on SLQIS.com ("Handling Different Row Types In The Same File") which seems close to what I need, but they are importing (ref: www.sqlis.com/54.aspx ). I'm not sure if I should just reverse this for export or use something different. Any comments are appreciated.
Diagram of Record Hierarchy
typeA (parent key, ...)
typeB1 (parent key, childSet key, date, ...)
typeB2 (parent key, childSet key, ...)
typeC (parent key, childSet key, ...)
typeD (parent key, childSet key, ...)
typeE1 (parent key, childSet key, date, ...)
typeE2 (parent key, childSet key, ...)
The record types B1 through E2 form a complete set. Each set has it's own unique child-set key. There may be one or more sets for each typeA record (although it's possible that typeE records don't exist in the most recent set).
Hi everyone,
There is a small problem encountered while creating a package in sql
server 2005.
Actually i am using a flat file which has 820 rows and 2 columns which
are seperated by line feed(for ROW) and tab(for COLUMN).after
importing i found that ther are only 800 rows imported into the table.
Ather verifying the input file i found out that there are some null
values in the second column so there is no line feed for those
values.
Can anyone please help me how to give multiple delimiters for the same
input flat file.
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;

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 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,
i need to import a fixed with text file into several tables in SQL 2005.
The file contains records that should go inte different tables and i would like to know the order of the design..
I also get some errors when trying to convert the text to unicode, even with the derviced column data flow task..?
flat file source -> Data conversation/Derived column -> aggregate?
I have not found the way of importing the file into several different tables in the DB.
Thanks for suggestions..

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.
Hi All,
I have a requirement wherein I have to read the data from a "|" separated flat file. Each row is specified this way...
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
<row>Data1|Data2|Data3</row>
.
.
.
.
I am specifying the row delimiter as : </row>{CR}{LF}<row>
When I create Flat File Connection and when I see the preview of columns...in the first row "<row>" remains and in the last row "</row>" remains...
I am trying hard to sort out and remove these extra string but unable to do so...
Please let me know how to approach this? How should I specify the Row Delimiter?
Thanks,

Hi,
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,

I have a simple SSIS package -> It reads a local text file which has 10 rows of data ( id, name, telephone # ) and puts it into a table.
It uses the "SSIS Flat File source" to read and a "SQL Command" to insert into the table. I can see that it reads line by line and puts each line into one row in my table.
Now, my production data is over 5 GiG of mainframe data and it seems their data is arranged in some hierarchical form.. so the position or arrangement of data in that file is important.
I pulled the data using my package and as far as I can see , my SSIS package pulled one line at a time ( from the flat file) and pushed it into my table. For each row, I also created an identity column in my table to be able to identify the positional arrangement of the hierarchical data and then use relational mappings to suit our business needs.
In all of this, my assumption is -
"SSIS reads one line at a time, inserts to my table and goes down to the next line .
It does NOT read a snapshot of rows from the flat file so as to write them into the table using internal ordering methods based on that particular snapshot "
My question is .. is my assumption correct ?
hi -
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?
New to SSIS and dts. Stumbling along on this one, really looking for resources and help.
I have a flat file, i defined through connection manager
and (for now) a fixed destination excel file I defined in connection manager.
My dataflow, is pretty simple, mapping two fields to each other an amount field and a phone field in a flat file source and excel destinatinon.
the amount column is formated as a number in the excel, and a currency in the connection and both input output properies.
A few questions,
1. why do cells on the excel show up with that green wedge on the upper left? appears to be a formating issue.
2. in the flat file, my amount field does not have the decimal, what would be the best way to apply that? it's should be implied.
3.Everytime I test the SSIS package, it keeps appending to the excel (it actually does not even work right on the second run). What's the best way to have it write to a fresh file? have an ssis script task copy the file from an empty template?
4. Id like to remove the last row? what's the best way to do that?
Thanks for any help or information!
Hi All,
I want to know is it possible to have source as Flat File and destination as XML
Thanks in advance,
Shagun
Firstly, I hope this question isn't asked too frequently but I found no existing reference to this situation....
I had a bunch of stored procedures in SQL 2k which imported and exported data to and from flat files using TEXTPTR, READTEXT, UPDATETEXT etc... The flat files were continuously changing so the filepath was a parameter for the sp.
The reason I used the pointer to flat files is because I didn't want to
load the files in memory before commiting them ie. with TEXTPTR and
UPDATETEXT I can import a 1Gb binary file 80000 bytes at a time and
keep (precious) memory usage down.
I was accessing this procs from a C# application.
Since these methods are going to be phased out by the guys at MS what is the best way of importing/exporting very large binary files in SQL 2005?
As far as I can tell SSIS requires a Flat File Source Manager object which needs a static filepath - not good.
Hope you can help,
Paul
Hi
I am trying to use a conditional split task so that I can check for specific fields. If the value doesn't exist I am piping the records to a derived field task, where I add an error. I then try to send these records to a flat file destination so that I can keep track of them. However, when I execute the SSIS data flow task I get the following error
[Log Invalid Records [5496]] Warning: The process cannot access the file because it is being used by another process.
This file isn't being used by any other process as far as I can tell, and the only process using it is the SSIS task trying to write to it.
If anyone has any ideas, then I would really really appreciate it
Thanks

Hi,
Here is my problem :
I work on a SSIS package with SQL SERVER 2005
I need to extract data from a table and put these data in csv files
But... the flat files name should be dynamic and assigned by a variable ...
Here's an example of my table :
Column header :
Id, Name, Number
1 TOM 22
2 TOTO 44
3 SAM 44
4 RADIO 55
I expect to have 3 csv files :
USER_22.csv
USER_44.csv
USER_55.csv
for example : USER_44.csv contains :
2;TOTO;44
3;SAM;44
if there's 50 different number, i expect 50 files
can i do that in a dataflow ?
thanks for answering
Hi,
We have a csv file which contains a date field. The data in the field contains "0" as well as "dd/mm/yyyy". Is it possible to update all "0" to "01/01/1900" on import using SSIS.
Basically when we import the flat file now it falls over due to the destination table data type being datetime.
If this is not clear please let me know and i'll try and explain more?
Thanks for any help.

Hello,
I have a DTS package that copies data from a fixed width file and inserts it into a SQL Server 2000 table. These files are generated daily, and usually contain about 200k records.
Sometimes, the format of the file between two days can differ slightly. I can't tell if the problem lies with the length of the record string, or the string terminator. The record string is supposed to begin with 'D1'. One file (as viewed in Notepad) will contain the records each in its own row, and each row will start with 'D1'. Another file will show that the first record starts with 'D1', but then the next record does not begin on a new line. Instead the next record continues at the end of the previous record. In this case, 'D1' is preceded with an unrecognized character as if it to indicate a carriage return.
Anyway, in SSIS, when I configure the row width of the fixed width file in the flat file connection manager to 386, and the beginning of all the records are all on their own row, the data processes without a problem. When the records do not all begin on their own row, the data will process fine if I change the row width to 385.
I don't have to compensate for this in DTS. Between SSIS and DTS, both flat file connections are configured with a row delimiter of LF, and no text qualifier. Why will SSIS and DTS process these files differently?
Thank you for your help!
