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!
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!

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 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?
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,

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...
View 4 Replies View RelatedHi 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!
Hi,
I am new to using SSIS. I am supposed to move data from a text file to a SQL Server table. I did that successfuly when I simply mapped column one-to-one, but when I could not conditionally map one column to different destination column depending on some criteria.
Example: I want to make SSIS map the column A depending on the value of field X:
If X= Value1 Map A -> B
if X= Value2 map A -> C and so on.
This is an urgent situation. I will really appreciate instant help.
Thanks,

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
A1JUN

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 have a For Each Loop that iterates over a recordset stored in a variable. One of the columns in the recordset is type xml and I want to map it to a variable using Variable Mappings of the For Each Loop container. I am getting this error:
Error: 0xC001C012 at FELC Loop thru report defs: ForEach Variable Mapping number 4 to variable "User::Parameters_xml" cannot be applied.
I have tried changing the type of the Parameters_xml variable to Object and String, but I get the same error. Any ideas?
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 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.
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!

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
Hi,
Is there a way to accomplish one- many or many -one or many - many column mappings in the SSIS data flow task or using any other tasks. We were able to do this in DTS Transform data task. Also is it possible to edit the mapping like:
dest column1 = Right(dest column1, 3)
Thanks.
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
I had to use use ssis 2005 in a short project recently & had littletime to work it out. I was importing a whole bunch of flat files intoSQL Server tables with many derived columns and transformations inbetween.It seems to automatically map columns from the flat file to columns inthe sql table where the names of the columns are equal. But can italso do it automatically on position, so flat file column 1 goes tosql table colum 1, etc, etc? In each flat file I had to manually clickand drag the columns across to map them which took a very long time asthere were hundreds of columns in some tables!Thanks.
View 3 Replies View RelatedI am just starting out with SSIS and trying to get the feel of data cleansing using it. But on my very first project for data cleansing I've got into this weird error.
My data flow is very simple, it has a OLE DB source, Fuzzy Lookup and OLE DB destination. I've built three tables for this purpose, one is source, one is reference (it will be used to match for the real entries in fuzzy lookup) and the last is the destination table.
In all the three tables I've a field of City which I'd like to Fuzzy lookup in the reference table and if it crosses certain confidence level, I'd like to insert to the destination table. City in all the tables has the same datatype, defined in the same way, it is varchar(50).
But when in the fuzzy lookup I try to map the Source tables City field to reference tables City field, it gives me this error:
The following columns cannot be mapped:
[City, CityRef]
One or more columns do not have supported data types, or their data types do not match.
Although as I have mentioned before, both have same data types and are defined in the same manner (i.e. I've just selected the datatypes for those columns and all the other settings are left to default). I just cannot understand why this is happening, plz help me with this. FYI I've also tried to give the City Column different datatypes in all the tables like varchar(max), text, Only to be greeted with the same error message.
Waiting for your reply!!
Regards,
Sajid.
I have a script and on one of the tables I keep loosing the mapping of the last 4 fields. If I go into the task it will ask me if I want it to automatically fix it and I say yes and remap fields but when I run it it bombs and comes back and when I go back into it it tells me there is a problem with same fields. It also rearanges the order and puts these fields last.
I have tried deleting and redoing the transformation only to have the same thing happen. Almost seems like a bug in software. I have seen this before but usually when I fix it it does not return.
Hi,
If you use a component that has a column mapping tab (most do) then you know that the component will try and map input and output columns automatically by name.
Is there a way to disable this feature when writing your own custom components? There is already a manual way to do this: rightmouse in the mappings tab of a component and chosen "Map Items By Matching Names". I find it is less helpful to auto-map initially because the designer tends to not think about the mappings.
A way of turning of auto-mapping in existing components would be cool too!
Cheers,
Martin
Hello,
I am trying to do the following:
I have been given an MS Access Database that has a table with columns
I have to create a spreadsheet that will have the data stored in the column header as a row (essentially we are creating a spreadsheet that records all of the different columns in all of the different tables in the MS Access DB).
Any suggestions???
Hi,
I'm having my first go at developing a destination adapter which will send data to an update Web Service.
I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings".
Which method defines the availble columns for the user to map?
Let me know if I haven't given enough information.
cheers
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?
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?

Hi,
I use lookups to map surrogate of level 1 dimensions to my fact tables in SSIS.
But how to handle a level 2 dimension with a ValidFrom and a ValidUntil date field?
I do not use an IsCurrent column, because this could problem with late arriving facts.
- In dts I used an SQL statement like this:
update SA
SET SA.DimProdRef = Dim.RecordID
FROM SAWarenEingang SA, DimProd Dim
where SA.ProduktNumber = Dim.ProduktNumber
and SA.ArtikelkontoBewegungsdatum between Dim.ValidFrom and Dim.ValidUntil
Now in SSIS I want to handle the whole thing in the data flow without using a staging table:
- Using Lookups: I would have to pass the date column for each inside the fact table into the lookup. That does not work.
- Using Execute SQL in the data flow: would be very slow, because the statement will be executed for any line in the dataflow
Any ideas?
Best regards,
Stefoon
Hi everyone,
I have a quizzing application where users log in, answer questions, and are ranked relative to each other. For this final ranking, I calculate their score using this formula -
score = (correct Qs answered) * 150 / (total Qs answered) + (total Qs answered)
The SQL query that i use to get this info is -
Code:
SELECT TOP 50 username, (sum(correct) * 150 / count(1) + count(1)) AS score, count(1) as totalq
FROM questionsstats
GROUP BY username
ORDER BY score DESC
This works just fine.
However, on top of this I need to put an additional restriction that only users who have at least answered 20 questions be counted in. How can I do this? Adding a simple 'WHERE totalq > 20' does not work. I get the error "Invalid column name 'totalq'.".
Surely there must be a simple way to do this?
Thanks.
