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,
awiora
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.

Hi,
I am building SSIS for 3 different files that have identical
schema and mapping logic.
In my OLE DB Source (object name - "OLEDBSource_SourceTable")
Data Access mode is "Variable name".
As soon as I swithced to this Data Acces mode
it started to give me an error:
[OLEDBSource_SourceTable [1]] Warning: The external metadata column collection is out of synchronization
with the data source columns.
The column "DEAL_NUM" needs to be updated in the external metadata column collection.
The "external metadata column "DEAL_NUM_Flag" (34529)" needs to be removed
from the external metadata column collection.
The "external metadata column "recordID" (33740)"
needs to be removed from the external metadata column collection.
I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have
Hi ,
I have a Package Consisting of the following (tried to portray the flow below)
1) OLE DB Source (Which I set the sql command for in code)

2) Rowcount Transform (Counts the Source Records)

3) Derived Column (Adds An AuditJobID ,ExecutionStartDate)
|

4) Conditional Split (Splits New and Updated Record - My Implementation of SCD)

6) OLEDB Destination OLEDB Update Command
I am trying to map the columns in the "OLEDB Destination" with c# ,with the following
IDTSInput90 input = oledbDestination.InputCollection[0];
IDTSVirtualInput90 vInput = input.GetVirtualInput();
As soon as I call the input.GetVirtualInput(); method I get a com exception ,Seem that I am missing a
VirtualInputColumnCollection on the component ,but can't seem to figure out why.
When I drop the all the other components and only keep the OLEDb Source and OLEDB Destination with a flow between them , the call to input.GetVirtualInput() doe not fail with a com exception and I can mapping normally
I really need some guidance on the above.

Cedric
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,

The only way to add a new column to an existing mapping that I know is to go to advanced editor and refresh. This however keeps only the default mapping (where the field names match), the rest is wiped out, so need to restore the mapping manually after that. Risky and annoying at the same time. Is there any alternative?
View 3 Replies View RelatedHi,
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.
Hi everyone,
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 created a Stored Proc to compute all the data I need to export to a CSV file.
I use the provider MS OLE DB Provider for SQL Server.
It's a very simple package with a single Data Flow Task.
This flow task is using an OLE DB Source to call a simple SQL Command : Exec MyStoredProc.
There are no params.
This Stored Proc is using table variables to compute the data.
It takes about 10 seconds to return anything.
The problem is that the mapping doesn't work with the OLE DB Source.
There are no fields at all shown in the mapping screen.
I tried to replace the Stored Proc by a version which only returns fields and no data.
Then the mapping would work just fine.
The package is then compiling and working fine.
But everytime I put back the real stored proc, even without changing the SQL Command, the SSIS execution breaks at execution.
It keeps saying :
"Error: 0xC0202005 at Data Flow Task, OLE DB Source [477]: Column "RecordType" cannot be found at the datasource."
My guess is that SSIS doesn't wait the 10 secs and thinks the Stored Proc is not returning anything.
What can I do to make this work ?
Thanks,
Vincent
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 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
Hi,
I have an Excel source, which I have hooked up to a Data Conversion task. I have defined "Output Aliases" for all my columns in the Data Conversion task.
However, when I try to map the columns from the Data Conversion task to the table columns, there is a list of column names, which do not correspond to the names I defined as "Output Aliases."
For example, one of the Output Aliases is "col1." However, when I go to map it, the column name is not "col1" but "My Excel file.col1".
Why is this happening? I have not had this problem before.
Thanks

I have a data flow that uses an OLEDB Source Component to read data from a table. The data access mode is SQL Command. The SQL Command is:
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare)
I wanted to add additional clauses to the where clause.
The problem is that I want to add to this SQL Command the ability to have it use a package variable that at the time of the package execution uses the variable value.
The package variable is called [User::Date_BeginningYesterday]
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare) and record_modified < [User::Date_BeginningYesterday]
I have looked at various forum message and been through the BOL but seem to missing something to make this work properly.

Hi,
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.

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?

from global varaibale(@@X)
2. execute xp_cmdshell to copy
C: empl_execel.xls to file in @@X
3.Run transformation
How to eliminate step 2 ?
If I run step 1 and 3 ,I get error "table does not exist"

How to create a new table dynamically in OLE DB destination.

I want to create a new table with name saved in a variable. I tried using OLE DB destination and assigning table name from variable. Does'nt work.
Thanks in advance for any insight on how to make this work.

Hi
In SSIS i have an execute SQL task where i get the job_id as the output which i set it to a package variable.
Now what I need to do is i have to map this value to one of the columns of the OLEDB destination.
How can I do it? Please help me ASAP.

Hi,
Is there anyway to dynamically change the Sql Server Destination? Let's imagine i want the data to go to a table based on a specific parameter like year for example...
Imagine tables like table1_2005, table1_2006 and i want to dinamically change the SQL Server Destination so it would insert 2005 or 2006 and so on....
I can't seem to find that option... It was really a good idea for microsoft to implement Expressions in such components... Dynamics it's all about it :)

Hello,
I am a beginner for the SSIS and would like to know how to modify the OLDEB Destination connectionString property at run time like using "for each loop container".
My requirement is that I have a single source which would be Sql Server 2005 and my destination is in MS-Access database residing in 100 places. I do not want to manually design in the data flow to these 100 destinations.
I have all the destinations stored in a table and would like to pick these destinations from the table and loop through the same at run time by modifying destination connection string.
I have planned using dts but the for each loop container does not work through as it works with flat file connection manager , but does not go well with OLDEB connection.
Highly appreciate any help in this regard.

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?

Hi
I am new to SSIS. Probaly What I am asking is the simple one. But I dont know. I have a requirement. My Data source is Excel file and Destination is SQL Server . Excel file consist around 10k unnormalized rows which should be loaded to the multiple normalized master and child tables into the destination with the Primary key (identity column) and foreign key constrains. Even sometimes package should check for destination database table for matching Source column (Excel) code with the lookup table code (destination lookup table) and get the Primary key of Lookup table and put it into the destination table. Please help me the way to find the solution for this
Given the following scenario, what kind of performance should be expected in transferring about half a million rows? We are seeing about a 9 minute execution time. Is this reasonable for about 460,000 records moving from source to target, with 3 inner joins from the source?
Source: Server A.OLTPDB
Target: ServerA.DataMartDB
Server A is running SQL Server 2000. SSIS is running on a different machine, Server B.
The reason for this is that we are distributing the SSIS package for use with a BI product built on SSAS 2005 and the requirements are such that the client could very well have the source OLTP database on a different physical machine than the data mart.
My understanding is therefore that:
1. SSIS will do all of the heavy lifting on Server B.
2. Even though OLTPDB and DataMartDB are on the same server, it is expensive for Server B to pull the records from Server A and then send them back to Server B, but with SSIS being on a different machine, this is inevitable.
3. In the OLE DB Source Adapter, specifying table or view has the effect of an OPEN QUERY command, whereas a SQL command with straight SQL will be executed on Server B and the former would be somewhat more performant.
Can you guys validate/dispel these assumptions?
TIA,
Rick
I have searched the SSIS forum for an answer to my question, and I think I have found my answer but what i have read does not come out directly and answer my question.
I am attempting to create an SSIS package that imports data from a Visual Foxpro table into a SQL Server table. From what I have read, the source and destination tables must match column for column. Is this correct? My SQL Server table has a few more columns in it. However, i consistently get "Cannot create connector. The destination component does not have any available inputs...blah".
From what i have read, it sound like the reasoning is that my source and destination tables do not match.
Is this correct, or am i barking up the wrong tree?
Thanks in advance...
