I am trying to implement fuzzy lookup transaformation in my ssis package. However, I want to understand the basic logic behind this component. what is the algorithm that is used here and how it works (in a simple languange)Â ?
View 7 RepliesI 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.

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.)Â Pull in the flat file to an ODBC staging table
2.)Â Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.)Â First lookup the information needed on patientID, providerID, date of service, and billing location.
4.)Â 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.Â
I am trying to run the Fuzzy Lookup on a SQL2K ref table using 2005 SSIS package and keep getting the following error:
[Fuzzy Lookup [2601]] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Cannot create a row of size 8061 which is greater than the allowable maximum of 8060.".
Regardless of the changes I make I cannot get this to work and it would make a huge difference if I could get it to run.
Can I create the FuzzyLookupIndex on a SQL2K database?
Any help or advice would be greatly appreciated.
Many thanks

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.

I'm building a package that is using the Fuzzy Lookup data flow item
and I'm receiving an error message that is troubling me!!!
"Fuzzy Lookup The length of input column is not equal to the length of
the reference column that it is being matched against"
If anyone can provide me any insight it would be greatly appreciated!

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 created a SSIS package with a Fuzzy lookup transformation.
It matches on 18 columns, looks for a 95 % match and has 50 variables that are passed through the transformation.
When I run the transformation it fails with the following error :-

I have tried all suggestions to fix this e.g. implement SQL Server 2005 service pack 2 - didn't fix it, up your virtual memory - didn't fix it.
Can anyone suggest what to do next ? Thx - Gary
We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.
We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).
After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.
We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.
Does that performance seem inline with expectations? Any thoughts to improve performance?
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?

Hello,
I'm trying to clean my data using fuzzy lookup algorithm though SSIS, but i get null values everywhere. This is what i did:
I applied the fuzzy lookup in a table (tblValues). As source table i have the tblValues, and as reference table in Fuzzy Lookup i have the tblValues as well, resulting null values in all fields/columns.
Do i have to create my own reference table? If yes, how do i do that and what values will i have in this table?I didn't understand how the reference table must be in order the algorithm to work. Any suggestions?
Thank you in advance!
I've been looking into ways to accomplish a fuzzy search and SSIS makes that possible if I want to do a bulk import or something like it. But what it I just want to look stuff up at any given time not haveing to run the package?
Is it possible to expose the fuzzy lookup outside of SSIS to for example t-sql?
Here's an example:
I want to lookup the music artist "Notorious BIG" but in the database it is "Notorious B.I.G." if I use the SSIS fuzzy lookup I basically get what I'm looking for. But how would I call this from a web application? So then I tried Full text search but this doesn't really work out as well.
Will I have to re-write the logic that the fuzzy lookup uses to enable it to work? i.e. using Full Text Indexes and FreeTextTable, ContainsTable, SoundEx and the like to somewhat even come close to what the Fuzzy Lookup has?
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:

View 4 Replies View RelatedHi,
I am using a fuzzy lookup to cleanse data from a sales line details table, during the import process. The sales order line details contains a filed called 'reference' and this is compared to a field called 'category' in another table.
Using data viewers to check through the cleansing process, I notice that the fuzzy lookup doesn't seem to match i.e.
tbl.salesline.reference = 'I3' -> tbl.sales.category ='I03'
the above is OK, but the lookup also returns the following
tbl.salesline.reference = 'I9' -> tbl.sales.category ='I01'
The value I9 doesnt exist, and is miskeyed by user entry, and should have been 'I99'. I would have expected the fuzzy lookup to pickup the I99 value as at least two of the chrs are matching, but no, it picks the first 'I*' in the table.
If I expand the fuzzy lookup to return more results, i.e. 5 per record, then it returns the first 5 results....I01, I02 I03 and so on.
Is there a way of improving the fuzzy lookup itself?
The enterprise edition of SQL server includes some advanced BI features, for example the fuzzy lookup feature of IS. If the IS package lives on an enterprise edition of SQL server and the database the package it is targeting lives on a standard edition of SQL server can the advanced features be used?

Hi Friends,
Can some body briefly explain me what is the difference between fuzzy lookup and fuzzy grouping?
thanks and regards
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".
Hi,
Could someone please help!
Im doing a fuzzy lookup based on 3 fields (Surname/DOB/Gender). The only difference between the two sets of data is the case of the first letter of the Surname.
Reference table has "Stuart" Lookup has "stuart", I have set Fuzzy Lookup Input for Surname to Ignore Case but still it won't match.
The DOB/Gender are Exsactly the same.
Why does this not work? I there a work around?
Many Thanks, Deano

Is it possbile to have multiple fuzzy lookup within a data flow?
I need to have at least 3 fuzzy lookup in a data flow. Here're the conditions that I try to find match: 1=Zip&City, 2=Zip&State, 3=City&State. I've the first fuzzy lookup working fine. After that, I've a conditional split to get any unmatch, then use another fuzzy lookup for a second condition...at this point, I get the error saying "The package contains two objects with duplicate name of output column _Similarity..." I do not need to get the _Similarity and _Confidence, so is there a way to exclude them from returning in the output?
Any comments?
Thanks in advance.
Hi everyone,
Ive just started looking at the Fuzzy Lookup feature and i think i must be getting something fundamentally wrong. I have two tables - each contain different meta data representations for a set of potentially similar documents. The only chance i have of matching a document in table A to a document in table B is a common title field. However, manual input means that the titles may differ in both tables although they are potentially quite similar in most cases.
In the lookup i get to specify the output columns from table B (Reference) which is fine, but i don't seem to get to choose the columns from table A that i would also like to see. So my output shows me all the documents from table B that it thinks are similar to ones in table A...but not identifying which record it's similar to.
I initially thought that the "pass through" columns that i identified would appear in the output - but this does not seem to be the case.
I must be using it incorrectly, but i have no idea how to progress with this apart from creating a new source table (C) which is a full outer join of table A and B - and then also using table C as the reference table, but that seems madness.
any help would be appreciated - ta
