Mappings Question In OLE DB Destination
Apr 10, 2007
Hi,
I have a situation where I want to map a column from a flat file to TWO columns in a table.
However, in the mappings tab, you can only select the "Input Column" once. Once a column has been used, it no longer appears in the drop down list.
I am wondering if there's a way to override this behavior, and if not, what is the best way to handle this type of situation?
I have added an EXECUTE SQL task to update the second column with the inserted column values, but I would like to know if the default mapping behavior can be changed, as it seems so limited.
Thanks

Here is the Scenario.
I have a flat file with name "Employee.txt " (Full url: C:Employee.txt) .The File content is like this
Anil,Engineering,1997
Sunil,Sales,1981
Kumar,Inventory,1991
Rajesh,Engineering,1992
(Note: Items are Comma Seperated)
Now, i have a SQL Server database called "EmployeeDB" which has 2 tables "TblEmp1", "TblEmp2".
The Table is like this.
TblEmp1 : Columns
EmpName EmpDept EmpjoinDate
TblEmp2 : Columns
EName EDate Edept
using integration services (SSIS) i need code(vb.net or c#) to Create a dtsx package so that i can push the flat file content to these 2 tables.
And the condition is :
After Executing the package Data loaded in TblEmp1 should be like this
EmpName EmpDept EmpjoinDate
Anil Engineering 1997
Sunil Sales 1981
Kumar Inventory 1991
Rajesh Engineering 1992
(No change in order compared to source)
And Data loaded inTBLEmp2 should be like this
EName EDate Edept
Anil 1997 Engineering
Sunil 1981 Sales
Kumar 1991 Inventory
Rajesh 1992 Engineering
Now, i know that we need to do like this in wizard
1) Create a flat file source component.
2) Create flat file connection and set the properties of flat file (delimeters and other things)
3) Create a Multicast Component.
4) Create a Path between Flat file source and Multicast.
5) Create 2 destination component(each for a table).
6) Create path from multicast to 2 destination components
7) Create a OledbConnection and set table names for 2 destination components..
7) Now,i have to do mapping for destination1.8) Now, i have to do mapping for destination2( this mapping will be different from mapping done for destination1 because iam not inserting the data in the same order in which iam doing for TBLEmp1.
I have done it in wizard.I need to do it through code and i know that its not complicated.Please find the attached file with this mail.i have attached a screen shot of how i have done in wizard.The main problem is Mapping differently for 2 destinations from source.for 1st one we can have a forloop for mapping.but for 2nd one iam confused!!

I have a data flow that consists of
OLE DB source which calls a stored proc that returns a result set
data conversion
Excel destination
I am in design mode in Business Intelligence studio. My excel destination (with an Excel Connection) shows no sheet name though I have an execute SQL task before the data flow to create the excel table called SHEET1. Needless to say, there are no output columns visible to do any mappings. I did go to the ExcelConnection to set the OpenRowset Property to SHEET1 but it seems to have no effect.
I can do the export in SQL Server Management studio and that works fine, but it is basic and does not meet my requirements. I have to customize the package to allow dynamic Excel filenames based on account names and have to split my result set into multiple excel sheets because excel 2003 has a max of 65536 rows per sheet. Also when I use the export wizard, I have the source as a table and eventually the source has to be a stored proc with input parms.
What am I missing or doing wrong? Thanks in advance

Hi all,
Is it possible to get information of the mappings availabe in the packages?, like the column mappings in the OLE Destination control, column mappings in the merge join control etc.,. I want the information of source and destination in the mappings(name of the DB, table). I want that to be in some file like excel file. Inform me is there a way to get it?
Thanks in advance,

Is it normal that my scd loses its mappings if I change one of its inputs?
When I talk about mappings, I talk about the first page of the scd wizard. I set everything (all the columns, business keys) and run the wizard until the last step. SCD creates two outputs (Changed and New Rows). All Ok.
If a column I use as input in the scd changes (for example, it is not a conversion column any more but a derived with the same name), my scd loses all the mappings!
It is very annoying since I have to map all of the columns again. Is this a normal behaviour of the scd or I' doing something wrong? Is there a way to 'repair' my mappings without needing to set one column at the time every time?

3.Is is adviceable transforming 5 to 6 text file with in one package in parallel

Is it possible to save column mapping definitions from a Transform Data Task? The practical use is I have four tables with very similar layouts of which 200 or so columns are identical. I have various front and back office applications that require local copies of this data in various formats. It is EXTREMELY tedious to remap all of the columns for each Transform Data Task required on these applications.
Is there a way to store all of the column mapping def's and import them into a new transform data task?

Hi,
My need is to load data from flat files to SQL tables. All the flat files are different. For convenience flat file name and table name is similar.
I have placed a For loop container and in which I used SCRIPT TASK to read the file names from the specified folder and i populated this value to SSIS variable. All my flat file name and destination table name are given using this Script task. For the first run it executes perfectly, but for the second run it fails. The reason is due to the flat file connection manager. The file name is changed since it is taken care by my script, but the columns are not mapped it still have the previous file's columns. I do not know how to solve this.
Please tell me if there is any other way to solve this or i need to refine my process.
Actually i have more than 100 files and so i am trying to do it at one short rather than creating individual packages.

Hi,
I have SSIS packages with the usual: source, destination, and mappings between the two. How can I export these mappings to, say, Excel / Word for documentation purposes?

hi -
I am totally new to SSIS etc and SQL 2005.
I have a dts task to recreate in SSIS. I have done most of them and muddled my way through, but this basic problem has got me stuck.
When mapping columns from my file to my ole db output table, I want to map one input column onto two output columns, but it will only seem to let me select one destination column for each input?
I have tried shift/alt/ctrl etc to try to get it to map to both columns but it wont have it.
How do I do it?
Also, somehow my Dataflow Sources tab has gone from the toolbox, and I can't seem to get it back any way - I switched on everything I could see and all components etc, but it is not in there as an option. How do I get it back in the toolbox?

restartability, is there any other tool option? like informatica
or
whether we have to implement through hand written query.
if query, then tell me how to do by taking scenarios like loading data from source sql table to target table.
suppose, in my target table, i have to load 100 records.
After loading 10 records,due to database downtime,or failure,
the loading stopped.
Either i have to truncate table or load it from 11th record.
Can u give me how to do this inside mapping
1)for table truncation
2) loading it from 11 th record.

Hi,
I want to retrive the output in a single SQL query.
I had two columns in a table; I used some values of column1 in column2.
I want to identify all the column1 vlaues in Left Hand side and column2 values in Right Hand side, with a single query.
example:
MasterTable
ParentRow ChildRow
--------- --------
A B
C D
E F
G C
H E
M G
Output required:
ParentRow ChildRow
--------- --------
A B
C D
E F
G D (C mapped tfrom D)
H F
M D (G mapped from C, and C mapped from D)
To get the above output, I written query using WHILE...[BREAK|CONTINUE] concept until I get @@rowcount become zero.
I am looking for better performace and to get the output in a single query, instead of multiple passes.
Can any one suggest good tools and articles on performance tuning techniques?
Thanks

Has anyone done this? I can't find anything in the documentation
that describes this. The closest I get is to the InnerObject property
of the TaskHost class. There is an example of programming a bulk
insert task. But I can't find anything on programmatically setting
the column mappings (source to dest) of a simple data flow task. Any
help is appreciated!

Hi, all experts here,
I am a bit confused for the model evaluation (lift chart), should we map all the columns for both the mining structure and the case table? I mean for those predictive models, we have a predict column, shouldnt we ignore the mapping of the predictive column between the mining structure and the case table? But it seemes we are not allowed to miss the predictive column mapping between the mining structure and the case table.
Why is that? Could any experts here give me some explanation on that?
Hope my question is clear for your help.
Thanks a lot and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

I get the following error when I try to navigate to a report/model/data source, stored in a Sharepoint Document Library using a Sharepoint URL based on an Extranet or Intranet zone - but it works OK using the url for the Default zone:
System.Web.Services.Protocols.SoapException: The specified path refers to a SharePoint zone that is not supported. The default zone path must be used. ---> Microsoft.ReportingServices.Diagnostics.Utilities.SecurityZoneNotSupportedException: The specified path refers to a SharePoint zone that is not supported. The default zone path must be used.
Is this a limitation of the SQLRS-WSS3 integration or is there a workaround?
Many thanks to anyone who can help!

Hey All:
I was totally confused.
When designing the SSIS dataflow part, firstly , i tried SQL Server Destination because my target server is a sql server.
then execute the task with failure.
Then i tried to use OLE DB DESTINATION instead of SQL Server Destination.
This Dataflow worked.
i can not figour out why.
By the way , i used the connection is OLE DB.And i choosed OLE DB source as the datasource cuz i can not find SQL server datasource.
Who can tell me some reasons for this?

Hello Experts:
I am trying to find a way within SSIS either automatically or manually/programmatically to allow an application to call the SSIS package for ETL and output the results to a destination specified 'on the fly' by the application.
Any ideas....

I searched, but couldn't find anything to match what I am looking for...
Basically, is there any way to tell DTS to create a new table each time that the backup is run? I am scheduling the backup for 1 hour intervals for 5 days, but need the databases that are backed up to be unique, so i would end up wiht 120 of them total.
Is there any way to do this through DTS? Or am I hosed?
Thanks in advance

Hi there,
I am using the SCD task, and noticed that the OLE DB Destination it generates does a "SELECT * FROM" from the destination table when i run my package (found this in trace). Now if this happens on a 20 000000 row destination table with computed fields on it, a lot of resources are wasted. Is there a way around this behaviour i.e. no select is done for the insert destination?
Thanks

Hello -
I am making good progress with my ssis package. However, there is one new thing which I cannot graps yet. That is, how to use variables when I want to update or insert a new row. I have some columns in my tables that require the datetime that the update/insert occured, the person making the change, and a few other things that are not part of the incoming data source (an excel file).
I created some user variables for these things, but I cannot figure out how to use them with my OLE DB Command and OLE DB Destination. One handles Inserts and the other handles the Updates based on whether a row in the Excel file is new (an Insert) or already exists (an update). Along with the insert or update, I'd like to set the Lastupdate, Who, etc.
Thanks for any help

when loading the transformed data into OLE DB destination, there is no options to truncate destination table first. Have to insert a middle step to run script to truncate the destination table first.
I'm very confused. We even has the options of keeping or deleting the data in destination table in SQL2000 DTS package. Why we don't have this option in SQL2005??
