How do i use the foreach loop container and pass each file found according to a specified pattern to a Flat File Source in a Data Flow Task Object so i can operate on each file found in the foreach loop object instead of having to specify a static file name
Thanks
Hi,
I am migrating one of my DTS package to SSIS.
My task is to read the filename from a database table and transfer the flat file data in to a table.
In SSIS,I am able to fetch the file name using a Data Reader Source; but how to pass this fileName parameter to Flat File Source ?
In DTS I have used ActiveX script to pass filename variable as flatfilecon.Source.
Any help ?
Thanks,
Ravi
I'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination).
With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table.
I used two different flat file sources and got the following:
Flat file 1: Bulk Import Task = 12,649,499 rows; Data Flow Task = 4,215,817 rows
Flat file 2: Bulk Import Task = 3,403,254 rows; Data Flow Task = 1,134,359 rows
Anyone have any guess as to why this is happening?
All,
I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!

I have a Data Flow Task within a ForEach loop container. The source of the flow is ADO.NET connection and the destination is a Flat File Connection. I loop through a collection of strings in the ForEach loop. Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:
[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process.
[Flat File Destination [38]] Error: Cannot open the datafile "Example.csv".
[SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.
I know what's happening but I don't know how to fix it. The first time through the ForEach loop, the destination file is updated. The second time is when this error pops up. I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.
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
My task is to write an SSIS package that picks up just one file from a directory and loads it into a database table. The filename is defined as being "ABC*.txt". So I must pick up only one file that matches that wildcard.
I can see two ways of doing this, but I can't get either to work:-
1. Use a Flat File Source connection and put the wildcard in the ConnectionString.
i.e. ConnectionString = "C:\mydirABC*.txt"
But SSIS doesn't seem to support that.
2. Use a Foreach Loop Container with a Foreach File Enumerator, and configure the enumerator as:-
Folder = c:mydir
Files = ABC*.txt
This works well, but loops round for as many files match the wildcard. Is there any way of forcing it to drop out after the first time round the loop?
Or am I missing a much easier solution?
Thanks.

Hi,
I am using a foreach loop to go through the .txt files inside a folder.
Using a variable I can pickup the filenames the loop is going through.
At present there is a sql task inside the foreach loop which takes the filename as a parameter and passes this filename to a stored procedure.
Now I would like to add one extra step before this sql task. Would like to have a dataflow with flatfile source which connects to oledb destination.
The question is:
While in the loop, how is it possible to pass the filename to the flatfile source using the FileName variable which I have created?
Please note, this is a different question to my other post.
Many Thanks
I have a package that runs fine by itself. But when I run it inside a Foreach Loop container on a parent package, I got a buffer error after a few loops. Here are a couple of the error lines:
A buffer failed while allocating 49085616 bytes.
The attempt to add a row to the Data Flow task buffer failed with error code 0x8007000E.
I already played around with the Data Flow tasks DefaultBufferMaxRows and DefaultBufferSize properties, and I am still getting the error. Just wondering if there is a memory leak or something with the Foreach Loop task. I havent install SP1. Maybe SP1 fixes this issue?
I have a DTS package of SQL server 2000 which has two "Execute SQL Task", which gets maximum ID (call it maxID1) from table1 in mysql and maximum ID (call it maxID2) from table 2 in sql server. Those 2 as global variables passes into a data flow which grabs all data from mysql's table1 with its ID > maxID2 and ID <= maxID1 and insert into SQL server table3. This package is working so far.
My question is how to achieve the same thing in SSIS? I created two "Execute SQL Task", which will get maxID1 and maxID2, and one "Data Flow Task". But how to pass those 2 parameters into that "Data Flow Task" without using "Script Task"?
Anyone could help? Thanks!
I have a stored procedure that is executed via a sql script task that returns a full result set. I map this result set to a variable or object type. Is there a way to use this variable as a data source in a subsequent data flow task?

Hi
Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.

Hello
I'm using the ForEach File task and masking the files I want to process as ABC??.TXT.
It all works well until I drop a file there like ABC12 Copy.TXT, which I don't expect to be process, but the loop still picks it up. Am I using the wrong wildcards?

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.

any suggestions on dealing with a flat file in the format below. I only want to process the data columns in the middle of the file and want to ignore all other rows. This was a very simple task in DTS with a small amount of VBScript in the transformation but it doesn't seem as straightforward in SSIS. thanks
......... file example ......
start-of-file
header1
header2
...
start-of-data

In many DTS packages I have used parameterised queries for incremental loads from Oracle database sources using the Microsoft ODBC Driver for Oracle.
Now I want to migrate these packages to SSIS, but the OLE DB connection for Oracle does not support parameters.
I cannot use the "SQL command from variable" data access mode because of the 4000 character limitation on the length of string variables and expressions.
Am I missing an obvious workaround?
I 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?
thanks
We have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.
I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.
To describe the data flow task - there are six data flows tasks (dft) working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.
The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider. The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.
select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS
C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR
The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns
select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.
The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.
insert bulk STAGE30([C1] varchar(100) ,[C2] varchar(100) ,[C3] varchar(100) ,[C4] varchar(100) ,[C5] varchar(100) , ... ,[C30] varchar(100) ,[T0] varchar(20)
Of course we then copy and transform the Staging30 data to the SQL table that equals T0.
But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?
I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
In DTS 2000 I had a situation where I had a text file as input source and text file as output source. On migrating the package to 2005 it puts a wrapper around it which executes it as a 2000 package, the rest of the tasks are neatly converted to 2005 style tasks. I presume this to mean that this will not be supported through to the next version, and there is no direct equivalent in 2005.
My question is how do I import a non-flat file source which has different numbers of columns per line. I did ,somehow, manage to do this with 2000 but cannot seem to get anywhere with 2005.
The flat file source seems to be expecting a common number of columns and just can't seem to cope with no column delimiters on some lines. If anybody knows different I would be glad to hear about it.
Raw data is not helpful to me as only works with a specific raw type (apparently)
Went onto Bulk Insert Task but got this message
[Bulk Insert Task] Error: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.Bulk load: An unexpected end of file was encountered in the data file.".
Have already browsed with this on web but only find comments about changing timeout setting.
Can find timeout settings in DataFlow source and DataFlow destinations but not in Bulk Insert Task.
As you can see this is a long and protracted question.
If the answer is simple I apologise if not blame Microsoft. Other than that have found SSIS has some nice improvements, apart from the odd vague error message I keep coming across.
Is there away to use wild card in the file name for the flat file data source?
Like //servername/directory/*.txt
At our business we are getting a lot of PDF documents that are being hand keyed into a database. Has anyone heard ior know of a SSIS Data Flow Source component that I coud use to read thos documents into a data stream (?) and process?
View 5 Replies View RelatedNeed to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1
Hi, all,
I have this SSIS data flow ( Flat file to sql server) that I want to add a step to redirect any "bad" data instead of fail out.
I had the red arrow hocked up to a sql new table to dump the bad data, but the flow still failed.
Here is the first error, and I knew what was wrong. A description field in that line has pipe(|) character in it, which also happen to be the column delimiter in this case.
[Flat File Source [1]] Error: Data conversion failed. The data conversion for column "Column 22" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
I knew if I fixed the data, every thing will be fine, but I just want to use this redirect feature of SSIS. Is there a place where I can turn off validation, or do something to make it work?
Thanks!
I am attempting to pull in data from a flat file data source that contains dates in the following format "01012007 10:22" which translates to Month Day Year and Military Time. I want to turn this into a DateTime format so that I can insert it into the proper column. I have a SQL statement which will do this (see bellow), but I can't figgure out how to run the statement on the data before it reaches its destination.
Can anyone help?
The code is:
Code Block
cast(convert(varchar(16),(substring( REPORT_RUN_DATE,1,2 ) + '/' + substring( REPORT_RUN_DATE,3,2 ) + '/' + substring( REPORT_RUN_DATE,5,10 )),1) as datetime) AS REPORT_RUN_DATE
my package has a flat file source that should be extracting data from a text file passing the data to the next component in the data flow. the package validates fine, but the data isn't flowing. however, i see the data in the source component. i added a data viewer between the source and the next component to see if any data flowed and saw no data. can someone suggest how i should go about trying to debug this? thanks.

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

I was getting the product error associated with the full version of SSIS not installed so I ran the installation again and selected the Integration Services check box.
Now when attempting to import data into a database, the drop down list doesn't have a flat file option.
How do I import data from a txt, csv file?

Hi All,
In one of my SSIS Interface I have to Merge data from a Oledb source and a Flat file source.But after I read from the flat file I have do a basic validation of the file for the length of header,detail and trailer records and then process further.The above Validation I am doing within Script Component.If the validation fails the flow should pass out of the DataFlowTask without Initailsing the Oledb source.
But the problem is i am not able to connect anything to the Oledb source,i.e Oledb source is not taking any incoming Pointers.
Earlier I had done the same Validation in Control Flow Task,but then the interface was reading the same file twice,once in the Control Flow Task and then again in the DataFlowTask.Which i should avoid now.
I hope many of you could have come across such a problem.
Any help on this will be appreciated.
cheers
