SQL Server 2012 :: Handling Flat File Destinations Dynamically?
Feb 5, 2015
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'.
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.
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 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.
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).
For some reason I am having a really hard time grasping IS and I have a task that I would imagine is easy.
I have a flat file source with 6 columns, I would like to import this file into two flat files. One file containing columns 1,2,3,5 and the second containing 2,4,5,6. I created the connection managers for both destination files, but I can€™t determine what transformation tool I need to accomplish this task? Could you help?
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...
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.
I need find out the number of columns in flat file before i process that particular file.I have file name in @filename variable and file path is @filepath variable.But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles And i am using for each loop container to read the file one by one and put the file name in @filename variable.and my file name like
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file.if it is not there then i have to send mail to client saying that file is not valid.I need to also calculate the size of flat file.
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.
From SSIS I need to export data to a CSV with spaces padding the end of each field before the delimited value. For example if I have three fields that are Nvarchar(10) I need it to be this:
Testing ,Test123 ,Again {end of line}
instead of this:
Testing,Test123,Again{end of line}
It's like it can do fixed width or delimited but not both. Is this possible without having to force the spaces into the data coming back from SQL? I already have the SSIS package written to export the data to CSV which works great, just need to find some way to add the spaces to the end of each column to satisfy requirements on the system being exported to. Also the commas need to be there too.
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
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?
The import from Flat File Source fails: Error 0xc02020a1: Data Flow Task 1: Data conversion failed.
The data conversion for column "ArticleName" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.". (SQL Server Import and Export Wizard)
I have changed the size of the column "ArticleName" (varchar) to max but the error comes up again.
The data i want to import came with multiple flat files. They all could import properly but this one is a problem.
I set up a connection file in order to move data from sql to csv files. I should be at the last step, the data flow. but:I don't see any flat file in my destination assistant.
I'm taking the liberty to announce the availability of a suite of articles on my web site about error and transaction handling in SQL Server. In total there are three main parts and three appendixes.
The first part is a short jumpstart, while Part Two is a long in-depth discussion of what can happen in SQL Server in case of an error and what commands that are available. Part Three covers implementation and has lot of examples as well as a facility for logging and raising errors.
The appendixes cover special areas: linked servers, the CLR and Service Broker.
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?
I have a package that contains 22 data flow tasks, one for each flat file that I need to process and import. I decided against making each import a seperate package because I am loading the package in an external application and calling it from there.
Now, everything works beautifully when all my text files are exported from a datasource beyond my control. I have an application that processes a series of files encoded using EBCDIC and I am not always gauranteed that all the flat files will be exported. (There may have not been any data for the day.)
I am looking for suggestions on how to handle files that do not exist. I have tried making a package level error handler (Script task) that checks the error code ("System::ErrorCode") and if it tells me that the file cannot be found, I return Dts.TaskResult = Dts.Results.Sucsess, but that is not working for me, the package still fails. I have also thought about progmatically disabling the tasks that do not have a corresponding flat file, but it seems like over kill.
So I guess my question is this; if the file does not exist, how can I either a) skip the task in the package, or b) quietly handle the error and move on without failing the package?
When I set up a Flat File, Excel, or XML source, I have to specify the complete file name, in particular the folder where the file exists. I would like to specify the location dynamically, via a variable or property -- but how?
I have a flat file which has a column (length of 24) . Whenever I have that column more the 24 char length, my package failed. I would like to know if there is any way if I can continue my package in this situation and send my bad row to the output table?
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.

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!
I am having 2 tables one is staging temp and another is main import table.
In my staging table there are 3 column Col001,Id,Loaddate
in Col001 column data are present with '¯' delemeter.
I am having function which is used to load data from staging to import table using one function.
this function create a insert statement.
My Existing function
-- Description: To Split a Delimited field by a Delimiter ALTER FUNCTION [dbo].[ufn_SplitFieldByDelimiter] ( @fieldname varchar(max) ,@delimiter varchar(max) ,@delimiter_count int
[Code] ....
I am unable to get correct statement with above function.
I am tasked with truncating and reloading tables from one server to another. Company policy prevents cross-server queries, but allows SSIS packages with cross-server connections. I am doing this for about 25 tables. I have the table names in a single table & I have created an FEL to execute tasks against each table one-by-one. It works fine to truncate all the tables. I run into issues, though, with the DataFlowTask. I'm able to tell it which server & table to dynamically connect from and to, but it doesn't know how to map the metadata. They're the exact same columns and field names in both source & destination.
