The Lookup Transformation fails to match this datatype when full caching is enabled. When partial caching is activated (Edit > Advanced, Enable Memory Restrictions > Enable Caching) the lookup works.
This appears to be a bug to me.
Hi,
I am trying to use a lookup in a package and check for some conditions. On the advanced tab, I am trying to modify the condition from = to <=. But the same doesnt work when the target is on oracle, but the same works fine on SQL Server and DB2.
Any idea regarding the same?
Thanks,

I am doing a lookup that requires mapping 2 columns in the column mapping section. When I do this, I get the error "Row yielded no match during lookup" . The SQL that I captured in SQL profiler does find the record when I run it in Management Studio. I have already tried trimming everything to no avail.
Why is this happening?
I tried enabling memory restrictions but then I my package hangs and I get a SQLDUMPER_ERRORLOG.log file with the following logged:

Why am I getting this error with "Enable Memory Restriction"?
Hi all,
I don't understand what's happening here.
I have a Conditional Split with 3 outputs. On the first output I have a lookup, when I execute the package I have 56 rows going through the Conditional Split, all rows are then going to the 2nd and 3rd output but the lookup on the first output generates an error "Row yielded no match during lookup".
I don't understand why the lookup is generating an error while there is no row going through it.
Any idea ?
Sébastien.
In SSIS. I am having trouble exporting records
that don't match from a lookup transformation. I get the following
error:
Row yielded no match during lookup.
I would really like to have a list of all records that did not match so
that I could send an email of those missing rows
Please give me solution with example
Thanks
I have configured a lookup transformation to 'redirect error' all no-matched rows to a text file using the flat file destination.
Now I want to send the same text file as an email.I Know email can be send using the send email task but i need to know where to place send email task and how to check whether flat file contains the error data.
Can we use the send email task on eventhandler and invoke the same in case of such error "row yielded no match during lookup" so that we can send the such non matching rows as an email.
Or else any other way to send an email after generating the text file ocntaining the non matching rows.
Please suggest using steps or example
Hello,
I have a peculiar problem in my project. My project design is like this
The number in (...) are count of records.
File feed (1000)

Fuzzy Lookup
against Table2
|
|
Split Fz Lookup results
(_Similarity >= 0.60 && _Confidence >= 0.85)
| |
| |
| Write matches to Table1 (250)
|
Fuzzy Group
Remaining rows (750)
|
|
Split Fz Group results
| |
| |
Write Canonicals Write Dupes
to Table2 to Table1
(300) (450)
This is basically a customer de-dupification project.
The Table2 has the canonicals and Table1 has the dupes (of the canonicals).
I already have some data in these tables and the new data is matched against the existing data
in these tables and classified as new customers and duplicate customers.
In the above process one could notice that the rows identified as dupes of already exsting canonicals
by the Fuzzy Lookup task are written into the dupes table (Table1) and will not be processed further down
the line in the project.
But in my case I see that those matches identified by Fuzzy lookup are further being included in the
Fuzzy Grouping also.
When I run this in debug mode in BIDS, it shows the correct numbers as I have depicted in the
illustration above. But, after execution, when I query the tables it shows that all 1000 rows
went through Fuzzy Grouping.
Any thoughts?
Btw, is there anyway to upload attachments to the postings here?
I have a fuzzy lookup task that compares a source list of contacts to a reference list of contacts with the default settings. I did some testing by adding seed data that I knew would produce somewhat high similarity hits. All of the seeded contacts but one came back with the expected high sim values. When I looked for the one that didn't, I noticed another match had come up but it had a very low similarity of .17. I then did some research and discovered the reason was the MaxOutputMatchesPerInput setting which was set to 1. I then set it to 3 and reran the package and sure enough my seeded contact that was missing before now showed up. I thought the best match would show up if the MaxOutputMatches was set to 1? That is not the case in my testing.
For example, Donna Mizeman was in the reference list. I added Don Miseman to the source list to seed it. The only match that came back was something like Dieman Abdul .... So the initial match had a similarity of .17 but when MaxOutputMatchesPerInput is set to 3 the best match (seeded) has a similarity of .72.
Anyone have an explanation for this?

Hello,
For one of my SSIS projects that does a fuzzy lookup on a table, I opted to create an index and
to maintain the stored index. The index got created and subsequent project execution was able to
use that index.
Now I want to update certain rows in that table. When I run the update statement I get the following error.
How can I retain the index and still be able to update the table?
update location_stage set batchid = 'APR07N'
where batchid is null and eventid = '20070528020041';
Msg 6549, Level 16, State 1, Procedure sp_FuzzyLookupTableMaintenanceInvoke, Line 0

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?

Hello,
The illustration below is for a customer dedupification project.
The Source file, containing customer name and address records, is conditionally split based on 7 ranges of substring(city,1,2) to distribute the load across 7 different threads for parallelization. Each customer record in the source file
is looked up against a reference table named Location_Stage for its existence using the Fuzzy Lookup
transformation.
The reference table Location_Stage has around 10 miilion+ records. The source file would normally have around 1 million
records.
I am wondering :
- if it would be possible to partition the Match Index of the reference table (NOT the reference table) into
7 partitions based on 7 ranges of substring(city,1,2) and maintain these partitions on different drives?
- if it is possible to specify a particular partition to be used by a FzLkup transformation?
- if the partitioning approach will improve the performance of the Fuzzy Lookups?

Hi there,
Not sure if this is the right thread to post this on but here goes:
I currently have an excel file, we will call it price for now. In this file I have details similar to those below:
100 200 300 400
100 $4 $5 $6 $7
200 $20 $30 $40 $50
300 $100 $200 $300 $400
400 $15 $15 $15 $15
At present in Excel, one uses the match and lookup function to determine the price of the length and height dimension. Example: 300 x 200 = $40
How can one perform this same task in SQL 2005? Is this even possible?
Your responses would be greatly appreciated.
Thanks,

I have a very basic Lookup in my SSIS package that looks up against two columns and outputs a row to a table. Now currently if there is no exact match, it writes a null in my destination table. How do I simply drop all those rows that dont produce an exact match? I tried using the 'Ignore' error output, but with that it writes NULLS into my destination table. With the 'Redirect' it is looking for a place to redirect the error (NULL) rows, and I dont want to deal with the hassle or writing these NULL values to a file or table just to delete them afterwards. I just simply want to forget about all those rows that dont produce an exact hit and only fill in the destination table with those that do produce a hit. How can I drop these lookup rows that dont produce an exact match?
View 5 Replies View RelatedHi All,
I am doing something really simple and it doesnt work, may be I am missing something, What I am trying to accomplish is to load a fact table using lookup transaformation, however my source data was different from the data in my dimension (or the datatype ) I had to use a data conversion task before my lookup , so the data flow is something like this source -> Data Conversion -> Lookup -> destination , I am getting an error at my lookup task where it says the "[Lookup [82]] Error: Row yielded no match during lookup". and then it just fails. I know for sure that there has to be matching data. donno what is it that I am missing.
Thanks
Is there a way to ignore the unmatched rows using Lookup without creating another destination (Error Transformation for red connector)?
View 5 Replies View RelatedHi,
I am totally new to SSIS.
I need an example of how to use a Lookup transformation. Basd on that i need to lookup for some recs and delete records from transaction table. I have used the Execute SQL task for this and i am able to achive my requirement. But now i am using XML configurations for Connection Managers and for that very reason i dont want to hard code the catalog names(database names) inside my Execute SQL task.
Can any one suggest me how to do the same using a Lookup transformation or any other.
Any suggestions will be greatly appreciated.

Hi,
I have a Dataflow task which loads data from a flat file to a Fact table named Inventory , doing a dimensional Key lookup with DIMStores - which is the dimension table for stores information.
If I have some rows in the flatfile whose 'Store' column doesnt have a corresponsing key in the DIMStores table, I want to insert all these stores in to DIMStores table and then update the Inventory table accordingly ..
Any idea how do to this ?
Thanks in Advance,

I have a question based on Lookup Transformation component. If using Lookup component, the data cannot be NULL for available columns mapping. How about I want to keep the NULL value like outer join instead of inner join? Is there any way to do since I have several Lookup components inside of my dataflow?
View 5 Replies View RelatedHi Everyone,
I'm trying to perform a lookup transformation. But the deal is, I have this one value that I am passing into the transformation, but I would like to gather all values that match the value I put in....does the lookup transformation do this? I tried it, and it appears as if it only returns one value for the one input. After the lookup, I have an access OLE DB destination setup...so I can capture all those values that corresponds to that one value I passed into the lookup. Does anyone have any ideas on how I can go about this?
Thanks!
Hi all,
In BOL it says: "The Lookup transformation performs an equi-join between values in the transformation input and values in the reference dataset. Using an equi-join means that each row in the transformation input must match at least one row from the reference dataset. If there is no matching entry in the reference dataset, no join occurs and no values are returned from the reference dataset. This is an error, and the transformation fails, unless it is configured to ignore errors or redirect error rows to the error output. "
I have a lookup transformation which is supposed to find a match on two fields in the reference dataset (a table in my case) but strangely, when I execute my package and the reference table is empty the lookup still finds match for each row of my input dataset.
Does anyone have an idea why? I could'nt find anything about that in BOL.
Sébastien.
I have a question. I'm using a lookup table which contains descriptions for a field from one of my tables. I have added a lookup query that looks like this:
SELECT STORE_DESRIP, BANNER, STORE_ID
FROM `stores.txt`
WHERE (STORE_ID = ?)
My main table (stagging) contains the store_id field. What I want to do is populate my destination fields (Store_descriptin and Banner) from the lookup table, based on the Store_id. I have written an ActiveX script that looks like this:
Function Main()
DTSDestination("Store_id") = DTSSource("store_id")
DTSDestination("Store_description") = DTSLookup("storelookup").Execute(DTSSource("store_ id")).value
Main = DTSTransformStat_OK
End Function
I receive an error when I try to test this script. It complains about line 8, which is the line that contains the DTSLookup function. Does anyone have any ideas what I'm doing wrong?
The process I see here is that when it comes to populating the "Store_description" field is will look the lookup table and based on the store_id, pass the description back. I would also like to add another destination field into this script, but won't until I resolve this.
Thanks for yoour support.
Hello,
I have a table like this:
Customer
Group
A
10
B
20
I need to do a translation of "group" to €œlocal group€?:
Customer
Group
Local Group
A
10
11
B
20
21
When a match is found, the group code should be replaced by the local group code ... but, when no match is found the group code should stay.
Is there any way to do this using Lookup ? I tried but when you set the error output to ignore it replaces the value that has no match with a NULL value. Maybe there is another way to get this done with or without the lookup component ?
I have a lookup transformation that retrieves a key for a certain column of values, in this case, a name. So, I go in to the lookup table with a name and come out with its key. I had it working and then I added new entries to the lookup table for a bunch of new names. Now, for some reason, I am not getting the matches for the new names. But I am still getting the matches for the names that existed before I added the new ones.
I'm wondering if the lookup transformation is using the old set of data and some how not picking up the new names. Do I have to trigger something in the lookup transformation to let it know that the lookup table data has changed?
Hello all,
I needed to lookup some table values based on a join of two fields...
I've configured the lookup transform to get the values via a SQL statement to minimize loading time.
However, when creating the relationships between the input columns and the lookup columns I receive following error:
input column [BATCH_ID] has a datatype which cannot be joined on
I've checked both input and lookup columns, both are of type DT_R8... Both columns in the different tables do have the same datatypes
Any idea how to solve this problem??
Thanks in advance
How to compare NULL to NULL in Lookup transformation?
I have a column (key) that has NULL value
and In my look up table, i assign NULL to -1, so i can get -1 when I join key to CD ( in lookup) ...
Num CD
-1 NULL
1 12
2 56
but when i run my package I keep getting no matching record.. i thnk it;s because of NULL value...
how can I resolve this?
I've been going round in circles trying to understand what design I should use for a particular transformation/lookup problem I have. Would appreciate a few pointers.
On the data flow, I can create the data source easily with a SQL Query that returns 4 columns...
eg. myDb.dbo.Table1
Col1,
Col2,
Col3,
Col4
The end result at the Destination is:-
myDb.dbo.Table2
Col1,
Col5
Table1.Col1 maps directly to Table2.Col1 -- easy
Table2.Col5 is a result of a lookup query to different tables in the same db based on the value of Table1.Col1, Table1.Col2 & Table1.Col3.
I've already had problems with the Lookup component that forced me to give up using it because it wouldn't adequately support parameters. I was forced to use the Script component instead. However, this problem is a bit different because I don't need to try and reference variables as parameters and, instead, I need to use the values from the source query (Col1, Col2 & Col3).
Suggestions?
Thanks in advance,
Clive
Hi,
There is one data flow task in the package. I have a column in the input set called "ID". The total number of rows in the input set is > 50000.
There is one table in the database which has the description for all the IDs. I need to get the "Description" value from the database for each row. The table contains nearly 12 lack records.
For that I am using lookup transformation. In lookup, I specified the query and column mapping and I got the new column "Description".
Here is the problem.
while running the package, the lookup is getting all the 12 lack rows from table and then it is matching the rows.
It is taking huge time.
Can any one suggest me how to improve the performance of this situation?
Thanks in advance.
Hi all
when using advanced tab in lookup transformation ?, for whatany suggest i will be appreciated , thanks in advance
Hi,
I just wanted to know if there is any way to Allow Null values while doing a lookup on a table in SSIS.
Let me elaborate the situation...
I have a flat file source that has a field called 'code'. I want to lookup in a code table to see if the code in the file is a valid code but the flat file may contain a NULL value as a 'code' (i.e. zero length string which treated as NULL by my package).
My problem is, the SSIS package tries to search for the NULL in the table and the lookup fails and an error is logged as per the business logic but actually NULL is also an acceptable value and the error should not be logged.
I tried inserting a NULL value in the lookup column but that doesn't work. I am not sure but I think I have read somewhere that two null values cannot be compared for equality. I cannot use conditional split to check the null value because I have to use a large number of lookups and a conditional split everywhere will mess up the things.
Is there any way to solve this problem?
I have the following query:
SELECT EMPID,EMPNAME from EMPLOYEE
where EMPID = (SELECT MAX(EMPID) from EMPLOYEE group by EMPNAME,insert_date)
Here one can use above query in Dataflow of SSIS and specify SQL to create temporary table and later can use as lookup to join to other table.
Is there any way in SSIS to directly do the MAX of EMPID in lookup and join to the main source table.
Any help is really appreciated.
Thanks.
I may have misunderstood how Lookupu works because it's not doing what I want.
From the OLTP datasource I have a long list of revenue items (from a SQL server database). I want to assign these to specific accounts as they are transferred into our accounting system. I have another table with a list of words to search for and which account they belong to.
For example if the OLTP source might be
Description - Amount
"Sales of cars"- "$20,000"
"Motorcycle sales" - "$15,000"
"Bike rentals" - "$2,000"
The account lookup table is like
Wordsearch - Account
"sale" - "ACCT_SAL"
"rental" - "ACCT_RENT"
So by looking up whether "wordsearch" is found in "desription" I should get an output of
ACCT_SAL - $20,000
ACCT_SAL - $15,000
ACCT_RENT - $2,000
Back in DTS I did this with an array and "If Instr" using VBScript in the Data Transformation Task. I'm sure there must be something in SSIS to do this - it should be something like a Fuzzy Lookup ?, but I'm drifting toward Script Component. Anyone got any ideas for SSIS
Hi,
Here is my problem for a lookup transformation:
I have an input flow with dates and fields like this :
ID BEGINNING_DATE ENDING_DATE
1 12/01/2006 12/16/2006
and a reference table like this:
ID PRICE BEGINNING_PRICE_DATE ENDING_PRICE_DATE
1 400 11/28/2006 12/03/2006
1 500 12/03/2006 12/06/2006
1 600 12/06/2006 12/09/2006
I have to get the intersection periods between the two tables joining on ID. I would like to have this result flow :
ID BEGINNING_DATE ENDING_DATE PRICE
1 12/01/2006 12/03/2006 400
1 12/03/2006 12/06/2006 500
1 12/06/2006 12/09/2006 600
I'm using a lookup transformation and modifying the SQL instruction in advanced tab like this:
select *
from
(select * from [dbo].[Price]) as refTable
where [refTable].[ID] = ?
and (? between [refTable].[BEGINNING_PRICE_DATE] and [refTable].[ENDING_PRICE_DATE]
or ? between [refTable].[BEGINNING_PRICE_DATE] and [refTable].[ENDING_PRICE_DATE]
or ([refTable].[BEGINNING_PRICE_DATE] between ? and ?
and [refTable].[ENDING_PRICE_DATE] between ? and ?))
In that case I have to define 7 parameters:
ID : parameter0
BEGINNING_DATE : parameter1, parameter3, parameter5
ENDING_DATE : parameter2, parameter4, parameter6
My problem is that the transformation looks for only one matching element and outputs 0 or 1 row per input row... In that case the 3 rows of my lookup table are matching with the row in my input table, but I have only the first one.
How could I do to resolve my problem?
Thanks... I hope it's clear...
Arnaud.
I used to use Lookup Transformation for my SSIS, now I am having problem and cannot find the problem. I have my source table, one lookup to join source column to my lookup column as L1. I then have another lookup to join L1 to L2, and will show L2. It seems not working. I used to have source to join several lookup and get different Li, not this one. Any help?
