Hi,
i'm creating a Lookup programmatically. But i can't find out how to assign the ConnectionManager that references the lookup data.
Do you have an example for me?
Many thanks in advance.
Stefan L.
I'm building packages programmatically and all is well. I have a new custom transform that I developed. It also works fine. Now I'm trying to add my new component to my packages when I programmatically build them, and I'm unable to do that.
Has anyone added their own custom components to a programmatically built package successfully?
I get a COM error on the line that calls ProvideComponentProperties. I've attempted various modifications including not overriding ProvideComponentProperties or just having it do nothing. I always get the same result. What I don't understand is that the custom transform works and handles ProvideComponentProperties fine when it is added to a package in BIDS.
Thanks.

I have a very simple problem I am trying to solve.
I have a table with a "DateEntered" field, and I have an ssis pkg set up to load data from a file into the database table. I just want to make sure that no one loads the same file twice in one day.
For example, if today is 8/22/07, and "DateEntered" is "2007-08-22", then I want to add a Lookup transform to run a query that will check and see if there's any rows in the table with a "DateEntered" is "2007-08-22". If so, don't load the file again!
Here's my query:
SELECT Code
FROM myTable
WHERE DATEADD(dd, DATEDIFF(dd, 0, DateEntered), 0) = DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0)
(all the dateadd stuff is doing is removing the time portion from the DateEntered field, so we are comparing apples to apples).
Now, if the query returns a bunch of "Codes" then we know that the data has already been entered for the day! So far, so good.
Now, how do I set up the Lookup to get it to work? I'm getting this error message:
Error 1 Validation error. Data Flow Task: Lookup [1299]: The lookup transform must contain at least one input column joined to a reference column, and none were specified. You must specify at least one join column. FXRateLoader.dtsx 0 0
But I thought I did this! On the columns tab, I have:
Lookup column: code
Lookup operation: Replace 'code'
Output alias: code
I have my error output set to:
Lookup output - redirect row
I don't know what I'm doing, obviously..........!
Need assistance :-)
Hi!
I am a newbie, grateful for some help. I have a Source Ole DB w sql-command selecting the customer.salary and customer.occupation, which I want to match with demo_id in Ole DB destination.
salary, occupation also in dim_demographic.
But in Lookup editor I find no column demo_id... how do I do this?
Please suggest me an article that describes 'Lookup Transform' (Specifically passing parameters) in detail.
Note: Is it possible to pass "variable" as parameters in Lookup transform?
Dear friends,

When I first try to lookup the date 17-04-2006, doesnt give me any records... and I need to create a new lookup for the next date from 17-04-2006. And in this example the next date is 18-04-2006.. How can I do it??
I made a sql query date gives me the next date with 2 parameters ... but I'm having some errors...
SELECT TOP 1 Data
FROM Spot_Rates
WHERE (Currencies_Name = ?) AND (Data > CONVERT(DATETIME, ?, 102))
ORDER BY Data DESC
In this exampple, the parameters returned from lookup1 is:
Currencies_name= 'DOLAR ESTADOS UNIDOS'
DATE='17-04-2006'
I need to create a second lookup transform to return the next date/currency for each row that didnt match in the first lookup...

Pedro
I want to do something relatively simple with SSIS but can't find an easy way to do this (isint it always the case with SSIS )
I have a column lets say called iorg_id, and I want to lookup the matching rows for this col in a table.
In this table iorg_id may have several potential matching rows. In this table there is another col called 'Amount'.
I want to retrieve for each iorg_id the matching iorg_id in the other table but only the row with the largest value in the 'Amount' col.
I couldn't find a way to do this all in the Lookup Transform.
I can match the iorg_ids and retrieve the Amount column, but can't find a way just to retrieve the matching row with the largest value in the Amount col. The only way I can think to do this is then run the output from the Transform through an Aggregate function and determine the Max (although haven't tested this yet).
Seems strange to me in that the SQL in the Advanced tab gives me something like:
select * from
(select * from [dbo].[Table1]) as refTable
where [refTable].[iorg_id] = ?
where I believe the first 'select *' is retrieving all the cols that are listed in the LookupColumns list in the Columns tab.
I thought I would be able to amend this to something like:
select max(amount) from
(select * from [dbo].[Table1]) as refTable
where [refTable].[iorg_id] = ?
but I get a metadata type error.
So, questions are:
Is it possible to do this all in the Lookup Transform are do I have to use the Aggregate function as I think ?
Why is it not possible to amend the sql in the Advanced tab to manipulate the returned data ?
I am trying to digest this logic, and have been unsuccessful so far. I am designing a package for incremental loads, but the destination table has a composite primary key on 2 columns, one of which is nullable. The source data comes from a SPROC. Uptill now, I have been banging my head trying to get this logic to work via the Lookup transform with a conditional split, but it doesn't work. Am I on the right track, or should I be using the SCD Wizard?
As a side note, I have been trying to work a solution using Andrew's blogpost on doing incremental loads: http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
Thanks.
Please indulge my ignorance, as I have only been using SSIS for a couple of weeks.
I'm trying to create a data warehouse using two input tables.
A column needs to be added to one table by using a lookup into the second table.
SSIS seems to handle the "no matches" and "single match" cases perfectly.
I can't for the life of me figure out how to properly handle multiple matches.
SSIS defaults to the first match, but I need to compute the "best" match.
Many thanks in advance
Scott!
Is it possible to use a VARIABLE in the Lookup Transform? I am setting the cache mode to partial and have modified the caching SQL statement on the advanced tab to include the parameterized query, but the parameter button only allows me to select columns to map to the parameter. I need to use a variable instead. I see the ParameterMap property of the transform in the advanced editor, but don't see how I can use this to map to a variable.
Can this be done, or do I need to use a new source, sort and left join component to accomplish the same thing?
Thanks!

Hi,
I get the following error when
i configure the lookup transform in the data flow task "Input column has a data type that cannot be matched".
This is the query that i use to set the reference table dataset
select firstname, lastname, address, email from customers_dimension cd , cust_test ct where cd.address<>ct.address.
I basically want to try and find all those records that have the same firstname, lastname, email in the customer dimension table where the records do not match. Both the input fields and the lookup fields have the same data type [varchar(max)].
It is pretty confusing, so much so that i did the lookup against the exact same table and got the same error.
Does anyone have a better idea as to what the problem is?
Thankyou
P.S.-This is the caching statement in the advanced tab
select * from
(SELECT firstName
FROM Customers_Dimension) as refTable
where [refTable].[firstName] = ?
I'm trying to lookup a value in another table linking on a column of datatype DT_R8. The lookup transform is complaining that I can't link on that datatype. However, the documentation says that it should work. I'm using the April CTP. Is this fixed in a later version? Any suggestions?
View 6 Replies View RelatedI am having problems with a lookup transformation. I have a row in my lookup table for blank ('') source data. If I test the join using SQL the match is made, but the Lookup transform doesn't consider it a match and sends it to error output. Is there a property that I don't have set correctly or something else I am forgetting?

OrderID = 5 Color = Black Quantity = 10
When i use the Lookup transform it cannot find the ColorKeyPK
The result of the Lookup transform is.
------------------------------
OrderID = 1 Color='Black' ColorKey=4
OrderID = 2 Color='Black' ColorKey=3
OrderID = 3 Color='Black' ColorKey=NULL ----> This is the problem Lookup cannot find empty string. It should be 1.
OrderID = 4 Color='Black' ColorKey=2
OrderID = 5 Color='Black' ColorKey=4
Thanks from now.
I've a simple lookup transform in SSIS 2008 (R2). I've created it with a full cache and it worked fine. When i switch to partial cache, it will give me this error:

ADDITIONAL INFORMATION:
Error at DFT_AdventureWorks [Lookup [411]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[Code] ....
I've created a OLE source with the following query :
SELECT
SalesOrderID,
OrderDate,
CustomerID
FROM Sales.SalesOrderHeader
And this will flow into the lookup transform and this has the following lookup reference query:
SELECT CustomerID,
AccountNumber
FROM Sales.Customer
WHERE CustomerID % 7 <>0
I have a package that works fine in development. I move the package over to test and it fails validation in the lookup transform.
Error 46 Validation error. Data Flow Task - PO Lines Interface: Lookup - LIST PRICE [29621]: output column "LIST_PRICE_PER_UNIT" (29667) and reference column named "LIST_PRICE_PER_UNIT" have incompatible data types. SPO_TO_ORACLE_PO.dtsx 0 0
What strikes me as odd is the fact that I don't have a way of specifying the data types. I just specify the column I wish to return as a new column with the same name. Anyway, why would this work in one instance but not another?
thanks

I am using the lookup transform with the following settings:
Reference table: Use results of an SQL query. The query retrieves the surrogate key and four business key columns from a dimension table which contains a few thousand rows.
Columns: business keys in the incoming data are mapped to the business keys in the reference table, and the surrogate key is looked up from the reference table.
Advanced: Enable memory restriction is OFF (and the other items on the Advanced tab are greyed out).
I assumed that this means that the lookup transform would cache all of the rows in the SQL query, and then perform the lookups against this cache. This is the behaviour that I saw when I was running the package in my local environment in the BIDS debugger.
However, a colleague was doing some profiling on our production database server, and noticed that the lookup transform is instead issuing a single SQL query for each row of input. Our production ETL server has many GBs of free RAM available (way more than enough to cache the contents of the lookup table in memory), and given that memory restriction is disabled, I don't understand why the lookup transform is behaving in this fashion. Does anyone have an explanation for this? I'm probably misunderstanding a key concept here.
Thanks,
Greg
I am trying to create a package that reads an input file or input table, does a fuzzy lookup, and outputs results to another table. I was wondering if this can be done programmatically? I have tried adding the fuzzy lookup component like this:
IDTSComponentMetaData90 FuzzyLookupDF = dataFlow.ComponentMetaDataCollection.New();
FuzzyLookupDF.ComponentClassID = "Fuzzy Lookup";
FuzzyLookupDF.Name = "FuzzyLookup";
I wondering how I can change the properties, such as what the input column is, reference table, lookup column, etc? I am not even sure if this can be done; if it can, I'd like some guidance on what the properties I would need to change are.
Thanks!

I have a requirement to access a lookup table from within an SSIS Transform Script Component
The aim is to eliminate error characters from within the firstname, lastname, address etc. fields by doing a lookup of an ASCII code reference table and making an InStr() type comparison.
I cannot find a way of opening the reference data set from withing the transform.

Below is C# code used to create a FuzzyLookup SSIS package programmatically. It does 95% of what I need it to. The only thing missing that I cannot figure out is how to take a Fuzzy Lookup Input column (OLE DB Output Column) and make it "pass through" the fuzzy lookup component to the OLE DB Destination. In the example below, that means I need the QuarantinedEmployeeId to make it into the destination.
Look in the "Test Dependencies" region below to get instructions and scripts used to set assembly references, create the sample tables used for this example, and insert test data.
Can anyone help me get past this last hurdle? You will see at the end of my Fuzzy Lookup region a bunch of commented out code that I've used to try to accomplish this last problem.

I work in the healthcare area, and am handling the survey data ETL's. There are around 8 different survey areas and based on information received from them for the visit they reference, I want to pull in more info from our invoicing database. My idea is this:
1.) Pull in the flat file to an ODBC staging table
2.) Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.) First lookup the information needed on patientID, providerID, date of service, and billing location.
4.) For the surveys that didn't match on those 4 columns, try looking up based on patientID, date of service, and billing location (since I could be 99% sure this would still return the record I need).
5.) For the remaining surveys, lookup based just on patientID and date of service. These records will be flagged for manual review because clearly, if a patient has multiple appointments in the same day, this will be prone to error.
However, in trying to use only 3 of the columns in the lookup, I get the error saying basically that I need to utilize all 4. Is there a way around this, or is there an entirely different way I should be approaching this? The reason I thought cache transform was the answer is because I will need to run a different package for each lookup, as the data and logic between each survey will vary, but the invoice data "pool" will stay the same regardless.
I would like to know what happens when a very large reference data set for a lookup transform with full caching enabled is getting loaded during package execution and the computer memory runs out or is very low.
Does SSIS
a) give an out of memory error of some sort
b) resort to a no caching or partial caching mode
c) maintain the full caching mode but will switch to using the paging file(virtual memory).
I think it will resort to using the page file in which case the benefits of in memory lookups are lost and performance would suffer. If I cannot upgrade the memory or shrink the reference set somehow, i should switch that lookup task to use partial caching or no caching with an indexed lookup table. Would this make sense?
Hello,
I have created SSIS package programmatically, I want to add Lookup transformation,
How can I add column from reference dataset to the transformation?
I have try to add new output column but it gives me an validation error, I write following coed to add new output column to lookup.
IDTSOutputColumn90 outputColumn = this.lookup.OutputCollection[0].OutputColumnCollection.New();
outputColumn.Name = col.Name;
outputColumn.Description = "Staging table output";
outputColumn.TruncationRowDisposition = DTSRowDisposition.RD_FailComponent;
outputColumn.ErrorOrTruncationOperation = "Copy Column";
outputColumn.SetDataTypeProperties(col.DataType, col.Length, col.Precision, col.Scale, col.CodePage);
Please suggest other way to add column from reference dataset to transformation output.
We are using lookup transformation in SSIS 2012. The lookup transformation queries a table with two date columns. When we hover the mouse over the two columns in the 'columns' tab of the lookup transformation editor, the two columns show as DT_WSTR instead of DT_DBDATE. This causes the SSIS package to fail due to data type mismatch.A similar abandoned thread is available at: URL....
View 2 Replies View RelatedI am trying to interpret some of the results I observe when trying to match similar records using a fuzzy lookup transform, but it's not entirely clear how the overall row similarity score is calculated. In particular, sometimes rows with lower individual column similarity scores will achieve a higher similarity and confidence score than a matching row with higher individual column scores.
The transform is configured with 6 text fields set to fuzzy mapping and a minimum similarity of 0, and 3 additional numeric fields with an exact mapping. It is set to return a maximum of 2 matches per lookup and to do an exhaustive search of the reference table.
For example, from the following matching pair of records Match 1 is picked over Match 2 even though it's individual scores are lower.
Match 1 Match 2
----------------- -----------------
_similarity_author 1.0 1.0
_similarity_title 0.85344648 1.0
_similarity_headline 0.0125 0.0125
_similarity_summary 0.0125 0.0125
_similarity_picture 1.0 1.0
_similarity_caption 1.0 1.0
_similarity 7.8429267E-2 7.3196657E-2
_confidence 0.55728668 0.44271332
In another case both matching records have *identical* scores for every mapped column and yet their similarity and confidence scores are different.
Clearly there are other factors involved in calculating the overall row score. Anybody know what these are?

Hi,
SQL Server Data Mining comes with "Term extraction" and "Term Lookup" for phrase detection. Rather than using the GUI tool, how to utilize these two features in coding? Please assist! Thanks!

Hi,
I have metadata that stored my table structure and relationship. I would like to know is it possible to create table relationship programatically? Any sample?
Thank you
Hi all,
I need to be able to create a DSN through code that connects to SQL Server using SQL Native Client. I have found the following article: http://support.microsoft.com/kb/q184608/. This demonstrates most of what I need, but it does not show how to set the username and password, which is something that I need to do.
Any ideas how I can do this?
Regards,
Stephen.
hi
my domain is hosted on a remote server
related databases are stored on a seperated DataServer
I have the name of that DataServer
and i need to create new DBs programmatically
I use this statement on my local machine
sqlstat= "CREATE DATABASE dbc_" + dbid + " ON PRIMARY" + "(Name=db_" + dbid + ", filename = '" & Server.MapPath("~/app_data") & "" + dbfilename + "')"
but it will not work , because i dont know the physical path
i cant use Server.MapPath()
How could i do?
thanks
I wanted to programmatically create SqlServer JobSchedule

I am using VSStudion2003 ,ASP.net with VB.net with SQL2000 as database .
ANY idea on how to do this ?????
Please help me?
Thank u all in advance
Hello,
What we'd like to do is programmatically generate and maintain a report model based on how the individual install is configured. I've found some documentation that makes me believe this is possible, but I'm hoping someone can nudge me in the right direction. The ReportingServices2005 class has several model related methods (CreateModel) and I found the .xsd for the semantic model XML file
(http://schemas.microsoft.com/sqlserver/2004/10/semanticmodeling/SemanticModeling.xsd),
but no real documentation on how to put together a Report Model document from scratch. Looking at the files generated from BIDS is somewhat overwhelming and I have no idea where I'd pull most of the information.
Finally, I want to create Report Model(.smdl) file without Report Model Designer.
I want to Implement CreateModel Method to create new model, any source code sample..??
Any help that can be provided would be greatly appreciated. Thanks!

Hi,
I am working on modifying a VB6 app that dynamically creates DTS packages to copy data from one database to another depending on the selections made in UI. The project currently uses DTSPackage object library and DTSDataDump Scripting object library.
We are in the process of upgrading the server to SQL 2005. I am exploring the possibility of replacing code that generates DTS packages on the fly with SSIS packages.
Is it feasible to do this in VB6 ? I have referred to similar posts which focus mainly on VB.NET or C#.
Any help with white paper or sample code would be appreciated.
Thanks in advance
Is there a way to do this? It does not appear as part of the standard SSIS API.
Thanks.
