Dynamic Transformation To Upload Flat Files Into Database
Feb 6, 2007
Hi,
My scenario:
I have 4 different flat files types each having different no. of column, order of columns etc. I want to upload all the 4 types into the same destination table in the SQL database. Before uploading I need to apply transformation to each column in the flat files. The transformations could be like
1) Multipying the source column by 100
2) Put an if condition for 2 source columns and then select one column to be copied into the destination.
I have the flat files schema with me and also all the transformations that are required.
Question:
Can SSIS provide me with a component that can read the flat file schema and the transformations from the database and apply them to the source data and then upload it to the constant destination table? Can derived column transformation be provided with the input columns list and the transformation to be done on each dynamically?
Why I want this way?
In future there can be an addition of extra flat file formats and we want to keep the changes to the SSIS packages to he mininum. Just entereing the addiional schema and transformation details in the database should run the package on the new flat file successfully.
Thanks for your time.
Regards,
$wapnil

HI,
As the source data of the cube is from MySQL, and the source data volume is more than 80M row per month, I have to build multiple partition in the cube, each partition contain only one month data, even though, the time to load data directly from MySQL is still too long, and because the mysql .Net provider and is not mature enough, the connection often break while loading, so I have to try to load from flat file which was exported from MySQL.
The Partition Processing Destination seems support this way, but, even it shows the partition name in component editor, it actually process the partition with partition ID, and there's not any way to change destination partition name for this component.
Unless I have to change the SSIS package every month, looks like it is impossible to make a smart ETL program that can dynamic create new partition with the ID and name as YYYYMM every month and load data directly from the flat csv file exported from big MySQL table.
Does anyone know how to load data from flat text, and also support dynamic destination partition name?
And I also find a bug in Partition Processing Destination, even 2005 SP2, if there's more than one cube in a SSAS database, and if two partition name in different cube is same, in component Editor, you can not set mapping to the second one with the same name, even you point to the second one, and click ok, the next time you open the editor, you will find it high light at the first one. And even it shows name in editor, it actually process with partition ID instead of partition name, this make it is not possible by change the partition name which need to process to a constant name, say currentMonth to force the component process it.
Thanks.

Hi guys,
Suppose I have a flat file that had columns that went like this:
rackId, cdname1, artist1, year1, cdname2, artist2, year2, cdname3, year3, artist3,...cdnameN, yearN, artistN
And I want to map it to a table that has the ff columns:
rack_id | CDName | Year | Artist
Assuming that N is constant and all rows of the flat file will have N or less values filled up per rack, how do I map the fields from the flat file such that cdname1, cdname2 and cdname3 all fall under the CDName column, year1 and so on will fall under the Year column, and artist1 and so on will fall under the Artist column?

I'm working on a web application that uses SQL Server 2000. Once I'm ready to upload my website to a production server, I need to know how to upload my SQL Server database files to the server. Are there actual files that can be uploaded? I've only deployed a website that works with MySQL to a production server, and there were no files to upload... the database had to be created on the server, and then the data itself had to be exported to text files (on my computer), then imported/uploaded to the production server using SQL statements...
How do I do this?
Thanks~

Hi,
I need to export data from SQL tables to AS400 files(the SQL table has the
same file name and column names as the file on the AS400) .
I created a DTS that has the following tasks: dynamic properties task, SQL
server connection, transform data task and a other connection(ODBC data
source).
I'm using global variables to dynamically set the source and destination
tables names on the transform data task. The problem is the transformations
are not automatically mapped and I get an error message when the
DTS package is executed with a source and destination that has
different columns than the ones specified in the transformation.
Any ideas or possible workaround would be greatly appreciated.
Thank you very much.

Im trying to upload 1000 txt files into one table in SQL. I'm using the following query, to upload one txt file at a time:
bulk insert [dbo].AAA_2013_2015
from 'dataserverSQL Data FilesSQL_EMELIZFC x Bloque Detallada201308 Detalle FacturasFACT_BLOQ_AGO13 (4).txt'
with (firstrow = 2,
lastrow = ???,
fieldterminator = ';',
rowterminator = '0x0A')
I'm trying that the query skip the last row because gives me the following error:
Msg 4866, Level 16, State 1, Line 1
The bulk load failed. The column is too long in the data file for row 1, column 17. Verify that the field terminator and row terminator are specified correctly.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".
know a command to skip the last row, something like lastrow= all-1...or something like that.
I also executed using MAXERRORS command...like this:
bulk insert [dbo].AAA_2013_2015
from 'dataserverSQL Data FilesSQL_EMELIZFC x Bloque Detallada201308 Detalle FacturasFACT_BLOQ_AGO13 (15).txt'
with (firstrow = 2,
fieldterminator = ';',
MAXERRORS = max_errors,
rowterminator = '0x0A')
does not recognize MAXERRORS command, also tried to put a number of error instead of max_errors.

In my package I am using lookup to get new and similar record. I want to filter the rows for Lookup Reference Data Set by using Variable Value.
I have created variable @[User::CustId] with Int32 datatype, having default value 2 when I am trying to evaluate below query I am getting error
"select CustId,PartNm,LocId,LocTyp from loc where CustId= "+ @[User::CustId]
Error. The Data types "DT_WSTR" and "DT_I4" are incompatible for binary operator "+".
The operand types could not be implicitly cast into compatible types for the operation. To perform this operation , one or both operands need to be explicitly cast with the operator.

I have a problem with a Sort Transformation, I have a CSV file with 200'000 rows the csv file is about 30Mb. When the rows are processed in the Sort Transformation, SSIS generates around 160 temp files of about 10Mb each.
How can avoid so many temp files to be generated ?

I'm trying to read the folder which has flat files and transform it and put it another folder with the SAME original name.
I created a For Eachloop containter and assign it to variable infile. In the data flow I added some transform and flat file destination. currently its reading 3 files and output is only one file.
I would like to create dynamic flat file connection so that it'll create separate files (same name) in different folder.
Thanks,

Hi,
I am trying to access from OLE DB source. And based on one of the columns, I need to write the data to a Flat File Destination.
For Example,
CustID, ProductID, Product Name, Product Description
Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
Code Snippet@DestFolder + [Data Conversion].ProductID + @TodaysDate + ".txt"
The ProductIDs are in the ascending order. Any help or guidance?
Thanks

Hi All,
I'm new to SSIS. I have a small problem. In our system we are trying to create flat files based on data from returned from different SQL stored procedures. The configuration settings for creating the flat files are stored in a SQL table.
For example, the config table will look like below :
Feed Id Feed Name Feed File Name Feed Stored Procedure Name
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 Biz C:Biz.txt dvx_GetBiz
2 PG C:PG.csv dvx_GetPG
3 NexT C:NexT.txt dvx_GetNexT
4 Amez C:Amez.csv dvx_GetAmez
The problem is dvx_GetBiz, dvx_GetPG,... all have different number and types of columns. So, I'm not able to create a dynamic Flat File destination depending on the columns returned from the corresponding stored procedure.
Is there a way to accomplish this ?
Pl. help.
Awaiting someones reply ASAP.
Thanks & Regards,
Vidya.

I am writing a package where the user uploads a flat file to a web folder. I need to automate this package to run everytime it sees a new file.
How can I implement this?
Can I make a call to a package or a sql server job to run from .net 2.0?
Do I need to use a service broker to look for a new file and run the package or a stored proc....I am looking for an async process where user doesnt have to wait for the package to run as it involves data validation of flat file and its huge...
Please help!!

I have number of csv files in a folder, all of them with same columns, need to be merged into one table and imported to sql server.
-The first row of the csv file is a header.
-The csv files are updated everyday
-The destination table is replace by new table with new info in the csv.
-The new csv files can be created and old csv files may no longer exist, but we are only interested in information contain in current csv files in the folder.
-I need SSIS to combine all the csv files in the folder and merge into one table.
-Other issue is that the field names may change in csv, so can the SSIS package recognize the change in field name and made necessary change in destination table as well.
Any insight on this issues will be greatly appreciated?

I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Any help or guidance here is greatly appreciated

Here's what I want to do -
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
Thanks

Hello Everyone.
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?

I will be receiving a CSV daily where columns within the file will change. The column order and number of columns can change daily. I need a way to read in the header from the csv and create a flat file connection that reflects the columns listed in the header.
Is there an easy way to do this using a script task? I have already read the header into a table but I have been unable to create the dynamic file connection.
