How To Pass Filename As A Dynamic Variable To Flat File Source In SSIS ?
Sep 3, 2007
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 ?
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
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?
Need 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:
I am wanting to capture the file name I am using to load data from and use it in a SQL statement to insert it along with the data that I load.
I am using a ForEach container to load all my .txt files but cannot figure out how to capture the name of each source file as it loops through the files and then add it to my insert statement that is populating my history table. I would think that the ForEach container has that information, but I do not see how to access it and assign it to a variable that I could use in my SQL statement.
I am trying to make a SSIS package that will loop trough all files in a directory and load information from them.
I can do this with Raw File Sources since they allow me to use a variable name as the file path, but I cant seem to do the same with Flat File Sources. Is there a way to change the connection to a Flat File Source on each iteration of a loop? Actually, if this is possible with all types of file sources (like excel files) I would love to know about it too.
I was thinking about renaming the file through a script task but that does not seem like the most elegant solution so decided to see if some one here knows of a more proper way before I go that direction.
I am writing a package that will process delimited flat files that will come in one of a few different versions. Within each flat file, the number of delimited columns will be the same, but each version of the file has a different number of columns. I have tried configuring the flat file data source to expect the version with the largest number of columns, but it will then throw away rows that have less than this number of columns (warning: There is a partial row at the end of the file).
Is it possible to use a single flat file data source that will work with all of the different width files?
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 "
I have a flat file that is row delimited by x00 x0D x0A. Any ideas on how to specify the row delimiter in the Columns section of the Flat File Connection Manager?
I'M NEW OF SQL SERVER BUT I'VE ALREADY GOT A LOT OF GOOD ADVICES BY YOU
I'M NOT IN ABLE TO RUN BY SQL SERVER AGENT AN SSIS PACKAGE:
THE PACKAGE IS MADE AS BELOW:
DATA SOURCE: FLAT FILE; OLE DB DESTINATION: SQL SERVER DBO.TABLE
I HAVE SEVERAL KIND OF DATA FLOWS SCHEDULED TO RUN DAILY, AND ALL OF THEM RUNNING CORRECTLY. THE ONLY ONE I'M ACTUALLY NOT IN ABLE TO MAKE RUN BY JOB IS THIS ONE. (BY VISUAL STUDIO RUNS FINE )
I'M GETTING BACK THE FOLLOWING ERROR: Description: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "Flat File Source 1 1" (32)
I'VE GOT A LOOK ON WEB, AND SEEN THAT THIS ERROR IS NOTICED WHEN SSIS IS NOT INSTALLED ON THE CLIENT MACHINE, BUT THIS IS NOT MY CASE SSIS IS FULL INSTALLED AND RUNNING.
I'VE ALSO TRIED TO RUN THE PACKAGE DIRECTLY FROM THE SERVER MACHINE...IT DOESN'T RUN EVEN LIKE THAT
I'VE DISCOVERED THAT SOME SSIS FEATURES IS NOT AVAILABLE WIT SQL SERVER STANDARD EDITION ( THIS IS MY LICENSE ) DO YOU HAPPEN TO KNOW WHETHER THIS IS THE CASE OR NOT?
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.
Is there a way to configure the XML source component to use a schema file whose filename is in a variable? Now I know it doesn't make any sense to have an XML source whose schema can vary, however, I have a parent package with a ton of child packages, all of which process the same XML input using the same schema. What I would like to do is for the parent to load the filename of the XML input file into a variable, and the filename of the XML schema file into another. Each child would have its XML source configured to pickup these variables from the parent, so that if the location or name of the schema changes, I don't have to edit each package one-by-one. However, it doesn't seem possible to specify anything but a filename for the schema. Any suggestions?
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?
I've just started looking at SSIS and have encountered what should hopefully be a simple problem to solve. I have a pipe-separated source file that looks like this (I've added Line numbers for simplicity):
In addition to a header and footer records, this file contains three record types for each person.
Record types are identified by the second column.
Each record type has a different number of columns:
Type 100 has 5 columns Type 200 has 4 columns Type 305 has 12 columns
The Row delimiter for all records is the {CR}{LF} character
I've set up a flat file input source and specified {CR}{LF} as the row delimiter for both header and data rows and the "|" character as the field delimiter.
It appears that SSIS is assuming that because the first data row has 5 columns, then everything must fit that format too. So the {CR}{LF} character that separates lines 02 and 03 is interpreted as text rather than a separation character and all remaining | field separators after 305 are interpreted as text containing in the fifth column. SSIS is also complaining that the last row is incomplete.
A bit like this (I've used tildes to indicate column separation):
I've seen one other reference to this behaviour but the response seemed to be SSIS doesn't know which columns are missing. In this scenario, we don't have missing columns, rather, we have different types of record in a single file. in DTS I would effectively parse the file once for each record type thus:
I have packages that must generate log errors dynamically including time of execution and the name of the task.
I make it changing the properties of the connection inserting two expressions.
1.-I alter the File Usage Type to 1 to generate this files. 2.- I alter the connection string as: @[User::myvariable] +"constant_description"+ time description+ +".txt"
The time description is : (DT_STR,40,1252) DAY (GETDATE())+"-"+(DT_STR,40,1252) MONTH( GETDATE())+"-"+(DT_STR,40,1252) YEAR( GETDATE())+" + REPLACE( (DT_STR,10,1252) (DT_DBTIME) GETDATE(),":","_") But it is not the problem
In those packages I have one connector for all the tasks and in execution time it creates one file for each of the tasks.
The problem is the way I insert in the filename the task name.
I have a pre-execute event handler in each task that modifies a string variable( myvariable) appending the task name. When I execute de package it works great but when I only execute a task, the program do not enter in the event and do not put the tasks name.
How can I put that name without using that handler? There is another handler can I use to do it that happens before the system generates the new file name and after pre-execute? Anyone knows another way to do this kind of things?
I'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!!
I have CSV file as source for SSIS package every time the filename will be changing like trd_1990M1_1990M12.csv,trd_1991M1_1991M12.csv , trd_1992M1_1992M12.csv etc.,
so it will vary as per user selection . i need to run the same SSIS package to execute the different file name with the same structure.
Please let me know the solution for that how to pass the file name dynamically to SSIS package.
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 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.

Using the Vb script above I am expecting to read the first row from a flat file source and transferring the data into two variable using script component.
I get the following errors one after the other:"The collection of variables locked for read and write access is not available outside of PostExecute." "Object reference not set to an instance of an object."
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
may be i'm asking a question that was discussed for billion time, but i can't find exact answer.
So i have access database that generates .xml or xls files by pressing button. So user select from drop down menu id ( e.g. 100,101,102,103 etc) and then file 101.xml or 102.xml or 101.xls or 102.xls is generating.
i need SSIS package to be configured to get filename is variable and then use insert data from xml or xls file to the related table
I don't understand how to pass file name through variable to SSIS package and then work with so called "variable".xls or "variable".xml file. Could you please give detailed answers if it's possible?
I have created a DTS Package in Integration Services 2005. Within the DTS Package declared a variable named xxx and passed a value 1234.
In the control flow i dropped a Data flow task and in the Property Expression Editor of DataFlow Task i defined Property = [DataReader Source].[sqlCommand] Expression = Variable name.
Now in the DataFlow Task Canvas dropped DataReaderSource.
How can i pass variable value to the SQLCommand ="Select * from table where name = Variable value.
I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post. Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows: Name : Scope : Date Type : Value FileCreateDate : (Package Name) : DateType : 1/1/2000 IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.

I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
