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 RepliesHi,
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 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?

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...

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

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'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.

Hi,If you have lookup tables which are used by multiple tables (e.g.'City' lookup table might be used by the 'Employee' and the 'Company'tables) do we need to link it to both tables? Or can it sit by itselfand just referenced?Cheers,Jack
View 2 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

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

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.

I've created a OLE source with the following query :
SELECT
SalesOrderID,

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.

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?

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 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.

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?
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?

I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?
Hey, did someone try to use the pivot transform?
It's not what you would call easy to configure...
In BOL there is the following section:
ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/extran9/html/55f5db6e-6777-435f-8a06-b68c129f8437.htm
I have followed the instructions there and I get an error when I try to map the new output column to the pivotkey:
"Output column "Yellow" (69) cannot be mapped to PivotKey input column"
So I mapped the new output column to the column holding the quantity values. This worked.
May this be a bug in BOL?
Further on I got some strange behaviour of the pivot transform:
My input is the following CSV-Flatfile:
sk1;sk2;pk1;qty
A;1;Yellow;2
A;1;Green;1
B;1;Yellow;5
A;2;Blue;3
A;2;Green;9
A;1;Green;5
If I omit the last line, everything is fine.
When passing the file as is into the pivot transform the output is:
SK1 SK2 Yellow Green Blue
A 1 2 1 NULL
B 1 5 NULL NULL
A 2 NULL 9 3
A 1 NULL 5 NULL
As you can see the key a;1 is duplicate. The cols SK1 and SK2 are my primary key of the destination table.
When the input is sorted by the first two colums the pivot transform throws an Error:
Error: 0xC02020CF at Pivot w sort, Pivot [39]: Duplicate pivot key value "Green".
I expected to have a sum over all Green for the key A;1. It seems that I have to use an aggregate which in my opinion should
be obsolete here.
As a conclusion I have to say that this task is far away from perfect but not bad for a start.

View 4 Replies View RelatedHi,
Something strange has happened to my table. I used Enterprise Manager today to delete 3 columns. When I went to re-link the table using Access Linked Table Manager, it gave me an error. I then deleted the link to the table, and tried to Link it again using 'Get External Data---Link Tables'. I am getting an error (no surprise!):
" 'dbo.tblSpaceUse.PK_RoomID' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long".
When I go into Enterprise Manager to 'manage Indexes' on the table, it shows me that the existing index is in fact dbo.tblSpaceUse.PK_RoomID.
About a month ago, I had to rename the index, because it had been pointing to the wrong table. The SQL I used to rename it (in Query Analyzer) is:
EXEC sp_rename 'dbo.tblSpaceUse.PK_RoomID', 'tblSpaceUse.PK_RoomID', 'INDEX'
I have been using the table successfully since then, until today. I have not done anything with the index; the only change I attempted was to delete 3 columns (not related to the index). I do not think I have made any changes to the table since I renamed the index.
I tried to run the rename SQL again (a desperate attempt!) and get the error message:
Server: Msg 15248, Level 11, State 1, Procedure sp_rename, Line 192
Either the parameter @objname is ambiguous or the claimed @objtype (INDEX) is wrong.
Any ideas on what went wrong and what I can do to fix it???

hi all,
good day!
i have dataflowtask_a and dataflowtask_b
i also have a send mail task
inside dtf_a i have a very long transformation which has 10 lookup task
each lookup task is configured to have an error output. should every lookup
encountered an error, the error output of the
lookup sends a unique error msg per lookup and is appended to a
string variable errorlst. Should dtf-a encounter an error it sets the variable
@nogo=true.
In the control flow if @nogo=false it proceeds to dtf_b otherwise it proceeds to
sendmail the consolidate error message.
Questions:
1. I only want to have one unique error message sent per lookup. if there are two
lookup error it should send only one message
2. the message should look like this: "error lookup1 : error lookup2 :and so soon"
how can i do this
thanks!
