Importing Multiple Flat Files To Multiple Tables In SSIS
Jun 27, 2006
I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?
I'm just learning SSIS. As I was following the tutorial on foreach loop container (lesson 2) to export multiple flat files in creating a simple ETL package in SSIS, I get the following error:
SSIS package "Take17.dtsx" starting. Information: 0x4004300A at Extract Cobra EBA, DTS.Pipeline: Validation phase is beginning.

The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. SSIS package "Take17.dtsx" finished: Failure.
I spent some time in understanding where could be the error. I traced it to the following place. If you take a look at the Lesson#2 in creating a simple ETL package in SSIS, using foreach loop container to import files into SQL server, as soon as I finish going through steps in configuring the file connection manager to use the variable for connectionstring, it immediately disappears. I repeated the tutorial three times exactly as I pointed out and when I reach to this step of configuring file connection manager for connectionstring, it takes the path and when I start debugging it, I get this error. When I go and check if everything is Ok, the connectionstring value is empty.
I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
I've tried to create a SSIS package to simply export a bunch of tables as flat files, and am having troubles because when the for each loop hits the second table the column mappings in the flat file destination are not synchronised with its schema.
I created a for each loop with an enumerator that returns the table names and sets a user variable.
I created a data flow task which dynamically connects to the table name variable.
In the Flat File Destination there is a column mapping property, but I don't know how to reset these mappings on each iteration.
I need to import multiple flat files with different formats into different tables of the sql server database and not able to figure out the best way out in ssis to do so...
What are the possible methods in ssis to do so and if possible the process which can be dynamic as file names or columns might change in future.
I'm trying to input a few thousand flat files into a few thousand tables in a sql databaseim using integration services with a for each loop to read all the files in a directorythe problem is i can only insert the data from all the files into one tabledoes anyone know a way to do multiple tables? maybe using some sort of variable?
I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
I have over three hundred text files that I need to import to SQLServer.Each is in the exact same format.I want to import tham as seperate tables.Is there any way to do it in one process?Regards,Ciarán
I have a folder on an SFTP server in our internal network which gets flat files periodically (almost every minute) from another server. The file structure is like this: Flat File Format•Line 1—List of field names comma separated •Line 2—List of field type comma separated •Line 3—Data comma separated •Line 4—Data comma separated and so on... All the files will be like this without the .csv extention. There are a lot of fields and creating a column for each field manually will be a pain. Heres what I am trying to do: 1. Create a process that runs periodically on the server and imports data from files into the SQL server table. 2. Use the information in line 1 and 2 to create the schema of the table and then ignore those lines in every import (the data should be appended to the existing data). What are my options? Thank you all,Bullpit
I have a client who is sending me 800+ excel files each month with sales data. Each of the files is identical in structure, but has sales data for different stores. I receive all these files at the same time.
Is there a method with Data Transformation Services where I can have it work off of all the files in a given directory. I can set up DTS to work off of specific Excel files with no problem, but what I would like to do is set up a DTS so it could pull from each of the 800+ files.
Is this possible, or do I need to look at a solution outside of SQL to consolidate the Excel files first?
The Excel file would have columns similar to the following: store_id, zip_code, sales, transactions.
HiI have multiple excel files of the same format in a directory.They are called book1.xls, book2.xls, book3.xls and so on.What is the easiest way to import the tab named sheet1 from each ofthe excel files to a databse using SQL server 2000 enterprise edition?Regards,Ciarán
I am trying to write (my first, unfortunatly) DTS, and am having some problems.
I need to be able to import multiple flatfiles (all in the same format, just with different schema), each one going into a different table. I have written an application to call my DTS, sending it variables for the tablename and the filename. This works fine when I test it on a single flatfile.
My problem is, the Tranformation object does not reset after each DTS call, so I get "Column does not exist" errors after the first successful import. I can go into the DTS Manager and reset the Transformation options, but that would defeat the purpose of automation. Is there anyway to reset, or another technique, the Transformation object so that it will continuosly work on files that use different schema?
I am very new at DTS, so please consider me "ignorant" when replying.
I am trying to import multiple .csv files to excel sheets using Script task in SSIS. I have trouble importing the reference that allows us to read and write to excel sheets. Can anyone help me create a script task that will import multiple .csv files to excel sheets.
I Have Multiple Flat Files in Source Folder(They have Naming Conventions With Todays Date ex: Flatfile_20082204_1,Flatfile_20082204_2,Flatfile_20082204_3 ), I need to Extract Each and Evry file by Dynamically, and Transform the Flat File then load that Flat file into the Destination Folder with Standard Prefix and Todays Date with a Sequence No ex:Flatfile_20082304_A,Flatfile_20082304_B, Flatfile_20082304_C
16 flat files all fixed width. Some over 350 columns.
Open flat file 1
extract id and go see if its in table 1, if true update table 1 with first 30 columns
otherwise insert into table 1 first 30 columns.
goto table 2, lookup id, insert/update next 30 columns...etc..etc..for 10 different tables
So I've got my flat file source, I do a derived column to convert the dates, i've got a lookup for table 1, then 2 ole db commands, 1 for update if lookup successful, 1 for insert if lookup fails.
How can I pass the id as a param into the update command so it updates where x = 'x'
also I need a pointer on doing the next lookup, eg table 2, would I do this as some sort of loop?.
If you can help great, but, please don't just reply with "I'd use this object"...then no explanation of how
Probably a stupid and regularly asked question but I can't seem to find an answer, so here goes,
we have 16 .txt files, some with over 350 columns.
That info from each individual file needs importing to multiple sql tables.
need to look at sql table1 does record exist? if not create new then add in data once its been transformed eg datetime from yyyymmdd into datetime values [managed to get this using derived column] for first 20 columns, otherwise do update for the 20 columns...
then look at sql table2 and repeat for next n columns....
So I was wondering is it going to be better to write this as a dtsx package? if so can you point me to an example
or should I just write the code as part of a code behind page that scrapes the info and does a standard update/insert procedure?
I'm trying import 7 tables from each of 30 SQL2005 databases into a SQL2005 Consolidation database. I can simply create data flow tasks for each one but instead I would like loop through a list instead.
I've created a table to house the names of the databases from which I want to import the data. I've created SQL task to return the database names from the table as a "Full Result Set". I've assigned the result set to a user variable (type = Object) an named the result name 0
What I'd like to do is create a data flow task which connects to each of the databases and imports 7 specified tables from each database appending the table name with my database name in the result set.
I'm stuck on how I'd set the connection strings in my OLE DB Source in my Data Flow task. Any insight would be greatly appreciated.
We are trying to use SSIS Import export wizrd to import the flat files (CSV format) that we have into MS SQL Server 2005 database tables. We have huge number of CSV files. Is there a way by which we can import these flat (CSV) files in to corresponding SQL server tables in a single shot. I would really appreciate this help as it is painful to convert each and every file using the Import Export wizard.
I want to combine a series of outputs from tsql queries into a single flat file destination using SSIS.
Does anyone have any inkling into how I would do this.
I know that I can configure a flat file connection manager to accept the output from the first oledb source, but am having difficulty with subsequent queries.
I have a package that contains three database tables (Header, detail and trailer record) each table is connected via a OLE DB source in SSIS. Each table varies in the amount of colums it holds and niether of the tables have the same field names. I need to transfer all data, from each table, in order, to a flat file destination.
Hi all,New to SQL Server - trying to create an SSIS package that will look forand import a series of Visual Foxpro tables (.DBFs) when they appear ina folder.The tables are/can be all different fields, field widths, etc. Withquite a bit of overlap though.The end result should be table "ABC.DBF" is pulled into SQL Server astable "ABC"Using: SQL Server 2005 Enterprise, SSIS, *latest* version of VFPOLEDBdownloaded from MSI have set up a package and tested it with several different tables andit works great - but I have to redo the data source and destinationeach time...I need to get this to be a somewhat automated process, pulling in all..DBFs no matter what they contain.Can I do this with SSIS alone (and variable substitution) or do I needto write a bunch of code...Thanks very much for your time and thoughts...
I have a number of XLS reports in template form. I want to move these to a new location on the File Server and after they have been populated move them to another location on the File Server.
I have seen some proposed solutions but I haven€™t found any that work. This should not be difficult and I envisage using a File System Task and a Foreach Loop Container. However passing the multiple file names to the File System Task errors repeatedly.
I am building a ssis package that imports multiple xml files containing data into the tables using one xsd file. I am using xml source task for this. I can only import one file as the primary key constraint gets violated.
I have four tables with four primary keys. The xml file does not have the primary key column data. So every time these columns get populated as 1, 2, 3, 4.
I am preety new to xml, so was wondering if anyone can help? Why doesn't the xml file have primary key column data?
I'm new to SSIS and have a question about the best way to generate multiple Excel files with my current package design. I have a stored procedure that I run from an Execute SQL Task in a foreach loop container, and it generates results as appropriate for each of the parameters it loops through.
What's the best way to take the result set from each of those executions and generate an Excel file from each set? How do I map that result set variable to be the input for creating a new Excel file? Is this best done as a script task somehow?
Should I not be using SSIS for this task? I thought I would just create a package and schedule it to run daily with SQL Agent, and it would autogenerate the Excel files as needed.
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data. When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
I am a bit new to SQL Server but not to DBA or programming per se. I am having difficulties getting either an Excel or Text flat file to import properly.
I guess it would be best to ask, using either SSIS or BULK INSERT, what options need to be entered for a typical excel flat file?
