I am new to SSIS and i got 1 assignment.
Requirement:
In my destination table i am having some 30 columns and the CSV files what i get may have 10 columns or 20. How do I map columns between source and destination dynamically?
I have some source files is there today it will have 4 columns..Tomorrow it will have 10 columns...my package is dynamically load the data to destination table..How we have do it in Using script task...

So I have to export from a SQL 2005 table to a dBaseIV table using SSIS. Easy enough, however the catch is that the tables being exported will vary. I can send variables to the the package calling the sql table name and creating the DBF file with the same columns on the fly.
The problem is mapping the columns. From what I've been reading there is no way to alter the mapping in a package at runtime. I was hoping that there would be some sort of auto mapping setting that would match on the field names but I guess not. Anybody run in to this issue and have a work around? Thanks in advance....

I am trying to to make a dynamic column mapping using the SSIS, the mapping will be stored in a seperate table, and based on the file name, the necessary mapping will be applied.
Please advise its possibility.
I was using the code in this thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1371094&SiteID=1) to create a console application which can build the SSIS package dynamically and run the package.
If the source column and destination column names are of different cases then the application was failing during the mapping. So I modified the for each loop like below. Still this is not a fool proof method, this will work as long as all characters in the column names are upper or lower.
for eg., Source column = empl_id, Destination column = EMPL_ID, in this case the below code will work. if the source column or destination column is Empl_Id, then the below mapping will fail.
Code Block
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
IDTSInputColumn90 vCol = destnDesignTime.SetUsageType(input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READWRITE);
try
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToLower()].ID);
}
catch
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToUpper()].ID);
}
}
So how can I map the columns irrespective of the cases?
Thanks
Have to create SSIS package for the below requirement:
I have source data in 2 excel files. Data from both these excel files should be loaded to the same single Fact table.
The column names in excel files and table are not same. I have a Reference table which has the column mappings between excel and Fact Table.
I have to refer this Reference Tabel for column mappings, plus i have to add some derived columns (Created_Date) to load the Fact_Table.
I have given a sample data structure below:
Source Data
Excel1_Order.xls
OrderNumber OrderQuantity OrderDate
Order10001 100 01-01-2011
Excel2_Customer.xls
CustomerNumber CustomerName CustomerAddress
[Code] ....
Is there any way to handle this in SSIS?
Hi,
My Destination columns are more than source columns....
So, how to do column mapping if my source and destination columns are different?
Thanx,

Hi all,
I am transferring a huge Database running on PostgreSQL to SQL SERVER using SSIS. I have already mapped all the columns between source and target tables. Is it possible in SSIS to get a graphical diagram showing all the source and targets tables and its mapping?
Thanks in Advance,
I have a condition where if column5 is equal to 1 then put column6 into the destination column "dest6", if it is not equal to 1 then put column6 in destination column "dest7"
What is the best way to do this in SSIS?
If I have to use the conditional split then do I have to copy my complete mappings, exact change this one column?
Thank for the help this mapping will take me a long time!
Hello everyone,
I am having a little problem with a simple package and I do not know if this is a known issue or that I am missing something.
I have a data flow task, a simple one, with an oledb source pulling data, using a select statement, from a sql server 2005 instance, and an ole db destination pointing to a table in a sql server 2000 instance. Both intances are standard edition. The table in the destination has a column which allow null values and has also a default constraint (getdate()), and this column is not present in the source. When I map the columns in the destination, I leave this column as "ignore", not being mapped to any column from the source. The problem is that when I execute the task, SSIS is trying to insert NULL value into this column, so the package fail with the error "can not insert NULL value into column myColumn". I wonder why is it trying to insert NULL value if the column is not mapped to any column from the source.
Is this a known issue or I am nissing something in the settings?
If the destination table has rowversion or identity columns, there is no problem ar all. I ignore those columns in the mapping and SQL Server feeds them as expected.
Thanks in advance,
Alejandro Mesa
I have created a package which transfers data from a SQL server source to an Excel Destination. The DataFlow Task works fine , if i pre-define the column names in the Excel Destination... But i run into an error when i give the blank excel sheet as my destination. I am unable to map any columns
A sample example is as shown above .. In the column mappings field only one column in the Excel shows up for mapping and eventually throws the error "[Excel Destination [42]] Error: The number of columns is incorrect. "
How do we proceed in this case , where in we do not want to give pre-defined coulmn names in the Excel Destination sheet.
Thanks,

Hi Friends,
I have a small problem in parameter mapping for Execute SQL Task.
I am using a delete statement with 2 conditions.
Followed by another Execute SQL Task which contains commit statement.
delete from tname where c1 = ? and c2 =?
where c1 is number(4) datatype and c2 is of varchar2(20) datatype in oracle.
The connection manager i am using is ORacle OLE DB provider.
I am passing 2 global variables i.e g_v1 of Int32 and g_v2 of String Type.
In the parameter mapping of the Executing SQL task, i am mapping these 2 variables for
c1 and c2 and changed the datatypes inside parameter mapping as Numeric for c1 and Varchar for c2.
I also set the property as ByPassPrepare = True.
When i am executing the package i getting INVALID NUMBER ERROR.
i believe the SSIS is unable to perform the implict datatype converison.
For the next run, i changed the g_v1 varible datatype to Double and also i changed the parameter mapping for c1 as Doble datatype.
This time it is working fine. I can see the Green signal for the 2 SQL Tasks.
But when i connected to Oracle check the count in the table, the data is not getting deleted.
Also,
I set the property RetainSameConnection = TRUE for oracle connection manager.
I am not able to trace this logical error.
The same is working fine in my local machine.
But i am facing the problem when i deployed the same on the client machine.
Is there any problem with parameter mapping?
What should be equialent Datatype for Oracle NUMBER datatype that should be used inside the SSIS package while declaring the global variable and
inside the parameter mapping.
Any thoughts!
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.
I have a report which runs for last 12 months data. Since this is going to be last 12 months the column headers change every month. How can we implement this with dynamic column headers in the dataset?

View 3 Replies View Relatedupdating a recordset contained in an System.Object variable during runtime.
I am trying to execute multiple file actions (plus parsing those files into a set of staging tables) at separate locations in parallel. I know I can do this in C# but I have a business requirement to use SSIS for all ETL operations.
Any one site can have 0 to many of 1 to 3 files. I would like to run multiple sites at the same time, so when all files of all types are completed at that site then go on to the next site in the list. I know I can do a single site at a time in a foreach loop but if I can run lets say 3-5 sites concurrently then I should be able to save execution time.
My thought is to have a recordset of the sites, when any 1 of the 3 (or more) "control flows" is open, update the recordset to let it know that site being actioned, when that site is complete, update the recordset that the site is completed, and so on.Or am I running in the wrong direction?
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.
Hello,
What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
Is this possible?
Thanks,

I have an excel file which has dynamic columns
i.e. Col1, Col2, Col3 this week. next week i will have a new Col4 in the sheet. This will keep on adding every week.
My problem is to Unpivot the data
Date 8/2/2013 8/9/2013 8/16/2013
Stock 1,561 1,661 1,761
i.e. the abobe table should become as
Date Stock
8/2/2013 1561
8/9/2013 1661
8/16/2013 1,761
How can I unpivot the dynamic columns given that the columns will keep on increasing every week.
I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.

For the Data Driven Subscription in SSRS we are using the following stored procedure
In Step 3 - Create a data-driven subscription
create procedure spRSGetReportSettings
(
@ReportID as integer
) as
begin
set nocount on
declare @t as table(y int not null primary key)
declare
@cols as nvarchar(max),
@y as int,
@sql as nvarchar(max)
set @cols=stuff(
(select N',' + quotename(y) as [text()]
from (select ParameterName as y from Reportsettings where reportid=1) as Y
order by y
For XML Path('')),1,1,N'');
set @sql=N'select * from
(select reportid,parametername, parametervalue from ReportSettings where reportid= ' + Cast(@ReportID as varchar(5)) +' ) as D
pivot(min(parametervalue) for parametername in(' + @cols +N')) as p'
exec sp_executesql @sql
end
Basically the idea is to maintain a single report parameter setting table for multiple reports.
Structure of the table is as given below
ReportID, ParameterName, ParameterValue.
Using Pivot we can generate the ParameterName/ParameterValue combinations for each report. This stored procedure is working fine in query editors(Management Studio)
But, in SSRS it is giving any results.
In Step 4 - Create a data-driven subscription,
Get the value from the database drop down, I am not getting any database columns.
Please help.

How would one add this as a derived column
CASE
WHEN Data IS NULL
THEN NULL
WHEN SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(CYCLE_YYYYMM AS VARCHAR(9)), 4, 6) IS NULL
THEN 0
ELSE RTRIM(SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(Data AS VARCHAR(9)), 4, 6))
END
From what I have seen the first option is not really required
I have a dtsx import script which import a delimeted csv file into a sql 2012 table. The default of the output length for all columns is set to 50 characters.All records which do not comply goes to another table in the same database. When I ran the script,all the records goes to the error table. I have now found a way to retrieve the column id and the error message to find that some column are been truncated and do not import.
I now need to know which column is given the error. The import file have more than 300 columns and I do not want to go and check each column length.I am using visual studio 2010 and using visual basic. I have found a sample of C+,but the screen shots is very small and when I type in the command,i do not compile.
We have over 400 import scripts and I could really use this in all of them to trouble shoot.
Hi Guys,here is my story.
I have a table with values stored in it and the Code Column contains sets of values that need to be mapped to a single value.For example i want the values ALMW,ARBAC to map to AL ARB and the values ARBIT,ARBOP,ARBSC to map to CU ARB and A1JAN,A1FEB,A1MAR,A1APR,A1MAY,A1JUN should map to AL AVG.
The values under Code are already in a database table and the ones under New Code are the new mappings for the values under code and are not in the database.
This table is referenced by other tables for the Code and i want those references to be done to the New Code instead.How do i modify the existing table or design a new table to preserve the current Codes and also map them to the new Code.
Code New Code
ALMW AL ARB
ARBAC
ARBIT CU ARB
ARBOP
ARBSC
A1JAN AL AVG
A1FEB
A1MAR
A1APR
A1MAY

Hey all! I have a bunch of questions, but let's start with this one:
Incoming from my flat file, I have two columns:
employee_id
dept_id
These indicate who did the work, and for which department (people can work for more than one department). In my destination table, I have the following two columns:
employee_id_sales
employee_id_wrhs
I want to map the employee id either to employee_id_sales or employee_id_wrhs, depending on the dept_id from the flat file.
How do I specify conditional column mapping?
I'm really new to SSIS, so I might be missing something obvious.
Thanks!

I am developing a transformation component and I'd like the gui to feature one of the mapping controls that are used for mapping input columns to, for example, SQL Server database columns in the OLE Database Destintation component, among others. I cannot for the life of me discover what the control is called or even whether it is available for general use. Can anyone help me out? Sorry if this is OT but it seemed like the people here would be the most likely to know immediatelly what I was on about.
Thanks

I have a data flow task in which I have a ADO NET source and OLE DB Destination. I have in the ADO NET source a sql command which pulls all the columns in a table. My requirement is to ignore a particular column,say column99. I opened advanced editor and deleted the mapping between the external and output columns for column99. I had also set the Error and Truncation to "Ignore Failure" for column99. I had also mapped the destination column to <Ignore> in OLD DB destination.
But this still throws the error-
Description: The ADO NET Source was unable to process the data. Field table-column99 missing an escape character for a quote.Unable to update PK WHERE clause.Error processing data batch.
How do I solve this?
Hi
I have migrated a DTS 2000 package to an SSIS package.
Half of it works fine, when stored procedures are called that don't use parameters they work fine on SSIS.
However when a SP is called with a parameter it can't find the parameter name ?
I have mapped the parameter under "parameter mappings" , the parameter is a simple date value
which is created at the beginning of the SSIS package in a SQL task.
it is saved as a global variable , and i have mapped this as the parameter , yet it still can't find the param. name ?
any sugestions ?
I'm creating a DTSX that will load flat file data into a table. Pretty easy, eh? Not with dates and times ...
The column in the destination table is a datetime data-type.
The date format in the source flat file is "m/d/yyyy" ("5/27/2007"). I know it doesn't have a time portion, long story!
When I create the package and transform the flat file data into the SQL Server Destination, the table column returns as a timestamp datatype. Moreover, there's no mechanism (that I've found) to force the destination datatype to datetime. There's DB Date, DB Time, FileTime, etc ... but no plain-old datetime.
Any help? An answer? An online resource? A book?
Thanks a mill'

Hello,
I am trying to understand the concept of left joins. I have the following query and am not sure about the left joins.
I am familiar with joins but the left join below is a little confusing.Below it seems like a third table is involved. Is this because there is no column to map to in the from table? Also, since tables sl and sc are mapped based on the SecurityID column and sl and ex do not have any common columns, table sc is mapped to ex using the left join? Which table's data will be returned based on the left join?
I checked the column type for the Exchange column(ex.LSECode) and it appears varchar(3).
SELECT SecurityID = sl.SecurityID
, Security = RTRIM(sec.Name) + ' - ' + RTRIM(sec.Description)
, Ticker = ISNULL(ids.RIC, ids.Ticker)
, Sedol = ids.Sedol
, ISIN = ids.ISIN
, Exchange = ex.LSECode
, Country = cty.iso_code
FROM #SecList sl
JOIN SecurityClassification sc
ON sl.SecurityID = sc.securityId
AND sc.source = 99
LEFT JOIN exchange_table ex
ON sc.ExchangeID = ex.exchange
Thanks in advance!!!

Does anyone know how to get destination coulmns to show up in the advanced editor for a custom component? I have a custom flat file destination component that builds the output based on a specific layout. It works as long as the upstream column names match my output names. What I want is to allow non-matching columns to be mapped by the user as they can in a stock flat file destination. The closest that I have been able to come is to get the "column mappings" tab to show up and populate the "Available Input Columns" by setting ExternalmetadataColumnCollection.IsUsed to true on the input. The problem is that the "Available destination columns" box is always empty. I have tried the IsUsed property on the output and pretty much every other property that I could find. On the Input and Output properties all of my columns show up under the output as both External and Output columns. Is there a separate collection for "destination" columns that I can't find? It's getting a little frustrating, is this something that can be done or do I have to write a custom UI to make it happen?
Thanks!
