Lookup Transform With Variable Parameter
Jun 8, 2006
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!

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 :-)

Dear friends,
I have a ETL that have a Lookup transform to get a rate from a table SpotRates.
The problem is when the match od some date in SpotRates Table doens't exist...
And for that records I need to lookup for next date...
For example...
SpotRate Table

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...
Regards,
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!

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?

I 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?

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

And this will flow into the lookup transform and this has the following lookup reference query:
SELECT CustomerID,

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 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....

I have a text box on a web application that allows the user to type what words they want to look. In the first version of the web application the user wrote the words he wanted and was wanted on the table by CONTAINS various words with the OR operator . What I wanted now was to allow the user to write several words, but with a particularity . The words that were inside '' was like a word.
I wish my transform variable, so that adding the OR operator, and the words within the quotes are not to put the OR.
ALTER PROCEDURE
@Product = ' 'ORANGE LEMON' BANANA APPLE 'PEACH PEAR' '
AS
-- I WANT TRANSFORM THE WORDS
@PRODUCT = 'ORANGE LEMON' OR BANANA OR APPLE 'PEACH PEAR'
What I meant was that even using the full-text functionality. I'm using CONTAINS . But before the CONTAISN was :
SELECT Description FROM Production.ProductDescription WHERE CONTAINS ( Description, PRODUCT )
Since PRODUCT and was researched by words such as ORANGE LEMON OR OR OR BANANA APPLE OR PEAR OR PEACH .
What is wanted now the words that come from the WEB application within '' stay as if it were the AND operator then was :
Product = '' ORANGE LEMON ' BANANA APPLE ' PEACH PEAR ''
PRODUCT = ' ( ORANGE AND LEMON ) OR BANANA OR APPLE OR ( PEACH AND PEAR) '

I 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?

FROM CallRecords
WHERE (CallDate = ?) AND (CallTime >= ?) AND (CallTime < ?) AND (Mid(CallRecordData, 30, 1) <> '9')
When I preview in the Transform Data Task, I get:
Package Error
Error Source: Microsoft JET Database Engine
Error Description: No value given for one or more required parameters.
When I look at the parameters, they are listed. I check their values, and they have the appropriate values (DateCalled, String, 07/14/2005) (StartTime, String, 06:30) (EndTime, String, 07:00)
When I run it in the build query or in Access with a linked table to the source, I can enter the values when asked for them and it works.

Hi,
I am pulling data from FoxPro tables into SQL 2005, and want to only pull new or changed rows. Accordingly each table in Fox has a column LastChangedDateTime, indicating the last time the row was updated, and I have a table in SQL which has one row per Fox table, listing the table name and the most recent data pulled into SQL.
In 2000 DTS I would have pulled the SQL datetime value into a package variable, then used a parameterized SQL statement with ".. WHERE LastChangedDateTime > ? " to select the rows I require.
In SSIS this approach does not seem to be possible, and the options are that I either use a variable for the entire SQL statement or, as the first SSIS tutorial suggests, use a lookup against the SQL table.
Gut feel is that the lookup will perform slower than creating the variable SQL and executing that (given that the source table is 13 million rows and rising, and I only want the last 100,000 or so from today).
What is considered best practice under these circumstances?
Also is it possible to write SSIS scripts in C# rather than VB.NET, as the syntax differences are driving me mad? ;-)
Thanks in advance,
Richard R

Hi all,
I haven't been able to get a variable to get its value from a query using other variables as paramters. Is this possible?
Here's my situation:
I have a table workflow
(
id int PK,
Quarter int UK1,
Responsible varchar UK1,
Stage varchar UK1
)
The workflowId is a composite key of the other three columns to keep the facttable rows narrow.
And a stored proc GetWorkflowId that looks if a certain combination of quarter, responsible and Stage exists. If so, it returns the id, if not, it inserts the row and returns the Id. So i can;t use a lookup or merge join, becuase the workflow row may not exist yet.
Now i need this workflowId as a variable in my package. (First a sql task uses it to delete old values, then a dataflow task would use it as a derived column to insert the new values.
Quarter is a variable in my package, and i need to lookup/ create a workflowid with the stored proc using Quarter, and then get the return value into a variable WorkflowId. Can i do that?
Hope i've been clear, if not let me know.
Thanks in advance,
Gert-Jan

Has anyone else noticed this? I want to be able to use a paremter in my reference table of my Lookup Transformation. I couldn't find any way for the dialog to accept SQL with a parameter so I checked on MSDN How to: Implement a Lookup Using the Lookup Transformation and sure enough in the article is says to click on the Parameter button. I don't have a Parameters button on this dialog. Error? Is this possible?
6. In the Lookup Transformation Editor, on the Reference Table tab, select a connection manager in the Connection manager list, and then do one of the following:
Click Use a table or a view, and then select either a data source view, a data source reference, or an OLE DB connection manager.
Click Use results of an SQL query, and then build a query in the SQL Command window, or click Build Query to build a query using the graphical tools that the Query Builder provides. Alternatively, click Browse to import an SQL statement from a file.
If the query includes parameters, click Parameters to map parameters to variables. For more information, see How to: Map Query Parameters to Variables in Data Flow Components.
To validate the SQL query, click Parse Query.
To view a sample of the data that the query returns, click Preview.

I'd like to pass a multi-value parameter to a stored proc to satisfy an integer field lookup.
example -
CREATE PROC SSRSQuery
@InPublicationId VARCHAR(500) = NULL AS
SELECT * from Table where PublicationId IN (@InPublicationId)
where PublicationId is defined as an int
I've seen various posts on how to split up the input string parameter to use in a string-based lookup but nothing useful for an integer-based lookup.
Any tips or tricks for this?

Is it possible to parameter the connection of a Lookup Transformation task - specifically the table/view name? I would like to be able to dynamically set the table that the Lookup Transformation is connecting to at runtime.I've looked into the "Use results of an SQL query" on the connection screen (which correlates to the "SqlCommand" property), but I'm unable to pass in a parameter this way.I've also looked into the SqlCommandParam, but that doesn't allow me to use a parameter in the "FROM" clause of the sql syntax.
