Dynamically Creating SSIS Package For Each Flat File
Apr 18, 2007
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).
And i want to use SSIS package dynamically load data from database into three separate flat file, each table into each file.
I know i got to use for each loop task ADO.Net schema row set enumerator, with OLEDB connection manager, select table name or view name variable from access mode list, but the problem comes, as table name is dynamic then flat file connection is also dynamic, i am using visual studio 2013...
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.
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 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:
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
I am a relative newbie to SSIS. I have been tasked with writing packages to import data from our clients. We have about 100 clients. Each client has a few different file formats. None of the clients have the same format as each other. We load files from each client each day. Each day the file name changes. I have done all of my current development work with a constant file name in a text file connection manager.
Ultimately we will write a VB application for the computer operator to select the flat file to load and the SSIS package to load it with. I had been planning on accomplishing this thru the SSIS command line interface. Can I specify the flat file to load via a variable that is passed through the command line? Do I need to use a Script Component to take the variable and assign it to the connection manager?
Is there a better way to do this? I have seen glimpses of a VB interface to SSIS. Maybe that is a better way to kick off the packages from a VB app?
I am struck at one point. I am trying to this operation and not able to go further.
1. I have got the dataset to a variable in the control flow.
2. I am looping through the dataset based on a coloumn.
3. Now inside my For each loop i have a dataflow task.
4. In the data flow task i am trying to build a dynamic query using the OLEDB Source and i have selected SQL Command from variable. And the variable build the Query as select * from @othervariable.
Now my question is
Can i send the data of each of the Query resultset to an out put text file using Flat File Connection? If yes pls guide me how? I have tried to create a flat file connection but i am failing how to map the data comming from step 4 dynamically for every query, since every query gives you a different resultset with different coloumns.
Hi, I tried to follow the widely talked about method to dynamically populate the connection string property of my flatfileconnection manager from a variable. I keep getting the following non-fatal error.
TITLE: Microsoft Visual Studio ------------------------------
Nonfatal errors occurred while saving the package: Error at Package [Connection manager "FFCM"]: The file name ""C:ProjectsSSISHLoadTOutputOut.csv"" specified in the connection was not valid.
Error at Package: The result of the expression "@[User::CsvFullFileName]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
Here is what I am trying to do. I have a foreach loop that iterates through a list of xml config files and reads the config information including the destination csv file name and does a data transformation. So I created a flatfile connection to a csv file did my data mappings. Created a package level variable to hold the destination file path In the Flat file conn. manager's properties -> expression -> set the @[User::CsvFullFileName] (which even evaluates fine)
When I try to run the package I keep getting the above mentioned non-fatal error..I checked the path and it is valid. I even tried
the c:\projects\...notation and the UNC path notation...all seem to give the same error
Anyone experience this before ? any thoughts would be appreciated.
I would like to fetch the data flow component name while package is executing. Since system variable named [System::SourceName] only fetches name of the control flow tasks? Is there a way to capture them?
After performing a join operation on two tables i get the below resultset
pid, fname, typename, pname, pcost
1, cad, bars, product-1, 100
2, har, witte, product-2, 120
3, nes, bars, product-3, 119
Now i need to create files with the obtained resultset like
Column 'fname' is the folder name and 'typename' should be the file in the particular folder.
For example the first record should be inserted into file name 'bars.txt' in the folder 'cad' and third record should be created in file name 'bars.txt' in the folder 'nes'.
Hi everybody, i'm a newbie to SSIS and I'm having a problem dynamically creating a new excel spreadsheet in SSIS. What I need to do is be able to dynamically create a brand new Excel spreadsheet after a data flow task completes.
My SSIS package automatically creates Excel files everyday. i want the excel files to get todays date when they are created . Eg:06152008 for today and 06162008 for tomorrow please help
After the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.
If you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.
Hi, I am new to SSIS and i have to develop a ssis package which will run in a production machine through VB.Net(2003) exe.I am facing a problem while setting connection string of SSIS package dynamically.Can anybody help me on this?
I currently have a list of User IDs (in a flat file) and I need to connect to a database I have read-only access to, so that I can retrieve additional data about these users.
I imagined a package that ran a query something like:
SELECT * FROM table WHERE UserID IN (<dynamically populated from flat file>).
Can somebody give me some advice as to how I can achieve this (either the way I suggested or another way).
I am in the process of moving from a 32-bit SQL Server 2005 Enterprise (9.0.3054) to a 64-bit SQL Server 2005 Enterprise (9.0.3054 with 4 CPUs and 8GB of memory on Win 2003 SP2) and the process has been very frustrating to say the least. I am having a problem with packages that I created on my 64-bit SQL Server. I am importing a few tables from the 32-SQL Server into the 64-bit SQL Server using the Task --> Import to create the package.
Sometimes when I am creating a package I get the following error in a message box:
SQL Server Import and Export Wizard
The SSIS Runtime object could not be created. Verify that DTS.dll is available and registered. The wizard cannot continue and it will terminate.
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (System.Windows.Forms)
Other times when I run a package that has run successfully before I get the following error:
Faulting application dtexecui.exe, version 9.0.3042.0, stamp 45cd726d, faulting module unknown, version 0.0.0.0, stamp 00000000, debug? 0, fault address 0x025d23f0.
The package appears to hang when running. By this I mean that the Package Execution Progress shows progress up to a point then it just stops. (The package takes about 17 seconds to run normally) CPU usage is at 1% and the package cannot be stopped.
I have deleted and re-created the package several times and I have also re-installed the service pack on the SQL Server (9.0.3054) but that did not help.
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.
I am looking high and low for some assistance with developing a VB .NET solution that I programmatically create a package and add tasks. I am adding a BULK INSERT task to load large FLAT TEXT files into SQL Server 2005 tables. When I execute the application I execute a package validation and it always returns FAILURE. I have been reading and searching like crazy and I have bought 2 microsoft books, TO NO AVAIL! Can anyone PLEASE help me with this. Thank you!
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.
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).
I am trying to dynamically create the connection to a database within an SSIS package.
the requirement is to allow the user to pass through the database as a variable and that variable will dynamically create the connection string in the connection manager.
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
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.
I have create packages which loads the data from flat file to sql server table, now I want to make my destination table connection dynamic what is format of connection string. I also need to pass user name and password for sql server dynamically in this case, what is the format for the connection string.
Also  in package i used ADO.net  as source for  *.mdb files how i can set the commection to .mdb files dynamically which is used as source in my package.
During my development of a ssis package i've noticed that when creating two control flows that pulling data from seperate tables, each going to its own flat file, that the second keeps the attributes of the column names from the first. So when I create my second flat file, not only does it have the names of its correct columns but has the name of the the first flat file.
I'm hoping that I've explained the correctly. I'll provide more info "OR" I can provide the code to package if anyone would like.
