Integration Services :: Lookup Transform Partial Cache
Sep 6, 2010
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:
--------------------------------------------------------------------------------------------------
TITLE: Package Validation Error
------------------------------
Package Validation 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 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 am using a lookup and full cache, occasionally i get this warning:[Lookup [150]] Warning: The component "Lookup" (150) encountered duplicate reference key values when caching reference data. This error occurs in Full Cache mode only. Either remove the duplicate key values, or change the cache mode to PARTIAL or NO_CACHE. Now I know it is only a warning but it is highlighting a real issue.Is there a way of capturing that this has happened?

I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.

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....

My source has 2.2 million of records. I'm performing the incremental load.In the lookup transformation i used the destination table for the reference using Full cache mode.For the first time package executed successfully but when i executed the package second time, Suddenly Package hangs while running.Than i truncate the data from the destination table and restart the SQL Server Services.After doing all this i executed package again and it worked but when i executed package second time, again package hangs up .I have 8GB RAM and i5 2.5 GHz Processor laptop.

After converting from SSIS 2008 to SSIS 2012, I am facing major performance slowdown while loading fact data.When we used 2008 - one file used to take around 2 hours average and now after converting to 2012 - it took 17 hours to load one file. This is the current scenario: We load data into Staging and Select everything from Staging (28 million rows) and use a lookups for each dimension. I believe it is taking very long time due to one Dimension table which has (89 million rows).
With the lookup, we currently are using partial cache because full cache caused system out of memory.Lookup Transformation Editor - on this lookup - how to increase the size on partial Cache size 64-bit? I am being stuck at 4096 MB and can not increase it. In 2008, I had 200,000 MB partial cache size.

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?

How do I know when its the right time to use the Cache Connection Manager? I understand that Full Cache mode eliminates the need to query the lookup table for every row.
Is the Cache Connection Manager intended for use by multiple packages that need access to the same lookup data?

I have a Pivot Transform in SSIS (2005) working perfectly, EXCEPT for that the first column of the output (the date) repeats for each of the following columns, which are themselves falling into the correct column, but not on the same line for a particular date as the others. Snipet of result from Data Viewer is:
dbDate site1 site2
1/1/2015 0:00 0.03 NULL
1/2/2015 0:00 0.04 NULL
[code]....

I have a question, I keep getting the warning where the lookup found duplicate reference key values when caching reference data. It also says to switch over to partial or no cache mode. I switched to partial and and it took way longer to run my package. I have around 200,000 records right now but this table will continue to grow. I guess my question is which mode should I be using? I have another table that will have millions of records in it.
thanks,

We are using the cache transformation in our project , while doing the cache transformation our disk space goes to 0 MB free and SSIS package execution not completes even after 3 hr..Initially we have around 34 GB free space on C: drive .Our server configuration is 64 RAM. We are caching the data from table which contains around 21 million records.We changed the path in properties (“BLOPTempStoragePath”,”BufferTempStoragePath”) of Data Flow task of SSIS in which we are using Cache Transformation.

We run std 2008 r2. I'm looking at the files this transform is complaining about. They seem to be named appropriately. The customerid folders don't exist when this runs. I'm going to put one in place to see if that is the problem.
The errors i'm getting are...
[Export Column [22]] Error: The file name "c:usersmyuserid heprojectnamecustomeridafilename.doc" is not valid. The file name is a device or contains invalid characters.
[Export Column [22]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Export Column" (22)" failed because error code 0xC020207F occurred,
and the error row disposition on "input column "FILENAME" (29)" specifies failure on error. An error occurred on the specified object of the specified component.
There may be error messages posted before this with more information about the failure.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Export Column" (22) failed with error code 0xC0209029
while processing input "Export Column Input" (23). The identified component returned an error from the ProcessInput method. The error is specific to the component,but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.

I have a fuzzy lookup in Integration Services Packages that does not seem to run. I am pulling data from a table in sql server 2008 R2 and comparing results to data from another table in sql server (same database & instance) using a fuzzy lookup for match similarities between the data sets. When my data flow task reaches my fuzzy lookup, a DOS box pops up for a second and then my packages finishes with a message of "Finished. Cancelled". The last message in my execution results displays: "Information: Execute phase is beginning". Again, there are no excel files being processed or utilized in this package. I've tried running my packages both in 32 bit and 64 bit mode.

In my package I am using lookup to get new and similar record. I want to filter the rows for Lookup Reference Data Set by using Variable Value.
I have created variable @[User::CustId] with Int32 datatype, having default value 2 when I am trying to evaluate below query I am getting error
"select CustId,PartNm,LocId,LocTyp from loc where CustId= "+ @[User::CustId]
Error. The Data types "DT_WSTR" and "DT_I4" are incompatible for binary operator "+".
The operand types could not be implicitly cast into compatible types for the operation. To perform this operation , one or both operands need to be explicitly cast with the operator.

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.

Hello,
Can anyone explain to me (or show me where to get info) in what scenario should I use Full Cache, Partial, or No_Cache mode in the Lookup task? I got below warning message during execute my package. I understand that my lookup data have duplicate reference keys. I want to change the mode to partial or no cache to see how it works, but don't know what to change for the parameter map.
Warning: 0x802090E4 at Data Flow Task, Lookup [37]: The Lookup transformation encountered duplicate reference key values when caching reference data. The Lookup transformation found duplicate key values when caching metadata in PreExecute. This error occurs in Full Cache mode only. Either remove the duplicate key values, or change the cache mode to PARTIAL or NO_CACHE.
Any info is appreciated.

I have an Excel file which contains some data. I want to load that into a SQL server Table. Here are my conditions :
1. If the table doesn't have any matching records from the Excel file, then my DFT should load the data from that Excel to the Dest Table.
2. If the table has even one or more matching records, then the DFT should not process at all, instead I should send an email to the business stating that there are some matching records and hence the package is not process...ed.
P.S. If i use Lookup, I have two matching and non-matching output. which will process the non matching records into the table and matching can be redirected to any flat/Excel file. But i don't want to do this. I just want to lookup the Sql Server table and excel.
It'll be good if there is an additional option in the Lookup "Fail component on matching records".

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
Date
Currency
Rate

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!

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!
Brandon
