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
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.
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';

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,
chris_kzn
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,
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.
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.
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?
Say I want to lookup a value in another dataset, but there is a grouping that requires you to know what the values for each level is in order to get to the correct detail record. Can you still use the lookup function with more than one field to compare against? So for example
Department
\___SalesPerson
\___Measure
I want to be able to add a new row at the Measure level, but lookup each field from another dataset. In order to do that I will need the Department AND SalesPerson values to do the lookup, but I dont think the Lookup function will let us do that will.
Hi All,
Actually this is in regard to SCD Type 2 Dimension, Scenario is like that I am moving Fact table from some old source and I have dimensionA description value in fact which I want to replace with appropriate id from Dimension Table and that Dimension table is SCD Type 2 based on StartDate and EndDate and Fact Table doesn't contains direct date value rather there is timeId in Fact so to update the value in Fact table I have to Join Time Dimension table and other Dimension Table to replace fact Description with proper Id.
Lets assume DimensionA Structure
id

StartDate
EndDate
Fact Table
id

measure2
TimeId

I am designing a ssis package,This is intends to mine text data(Data extracted from websites).
Term lookup/Term extraction has been used as tools for mining.
I have lookup terms defined with me for reference table,but the main problem lie in extracting the nearby text/number/charcters to these lookup terms during mining.
For example :
I found noun "Email" 200 (frequency score) times in my text,Now I want to extract nearby email address(this is also true for PhoneNumber,Address attributes also).so how can I achieve this with SSIS.
If u have some idea/suggestion to carry out this challenge with or without Term Extraction/Term Lookup,plz do write here.

Hello,
I am writing a SP, inside the SP i have a select statement.
I also have another SP, when i run it, it sends a list back with all the users that are currently online.
Now in my first SP, i want to construct a select statement that returns a users data, but only for the users that are online.
This is the first SP (GetAllOnlineUsers), that produces a list with users online (just abit rewritten from the membership function total users online):
SELECT u.Username FROM dbo.aspnet_Users u(NOLOCK), dbo.aspnet_Applications a(NOLOCK), dbo.aspnet_Membership m(NOLOCK) WHERE u.ApplicationId = a.ApplicationId AND LastActivityDate > @DateActive AND a.LoweredApplicationName = LOWER(@ApplicationName) AND u.UserId = m.UserId
This is my second SP, in witch i want to get the online users data:
SELECT m.username, d.data1, d.data2 FROM m.userstable INNER JOIN data ON (data.username = m.username) WHERE (m.username IN (EXEC GetAllOnlineUsers))
Is it possible to exec a SP into a select statement?
It seems my sysindexes table is inaccurate on a nonclustered index. In my case the rowcount (rows and rowcnt) do not match the actual rowcount of the table. The command UPDATE STATISTICS doesn't change the rows or rowcount, adding 'FULSLCAN' won't budge rowcount either.
After I did a dbcc reindex, the number of rows matched, however, upon adding rows in the table both rows and rowcount are out of sync again.
It's a fairly straightforward table, no triggers, no computed fields, only integer, datetime, varchar and bigint columns. There's a clustered index on a bigint column and a nonclustered index on a integer column.
dbcc show_statistics show that the nonclustered index is updated and it's rows and rows sampled match the number of rows in the table (not in the sysindexes-table).
I'd like to know if I'm chasing ghosts here or if there's something very wrong here. What could be causing the counts being inaccurate? Anyone who could shed some light?
I have this sql statement:
SELECT Countries.Name, Companies.ShortName, Persons.FirstName, Persons.LastName, PersonSkills.Skills
FROM PersonSkills INNER JOIN....
How can I choose a certain value from PersonSkills.Skills?
for example, I would like to choose a value from PersonSkills.Skills that matches a certain product. I can do the Max/Min value but the selected value needs to match the product.
The tables that I have are:
PersonSkills:
id, ProductID, Skills
Product:
id, ProductName
Ive been reading and playing around with this without success.
I want to select Property names or owner id from table A where there is no match between owner ID in table A and B , for example Property 3 in red. In table A only one person can be listed as owner of property. In table B many people can be listed as owner of the same property.
The way i script will return property 1 twice (as no match) because the owner ID from table A '123456' mismatch twice with owner ID from table B
'111111' and '222222'. I dont want Property 1 to be selected at all because the owner '123456' is listed as one of the owners in Table B
I have two tables in the same DB, one named “Client” one named “Case”.
-One column inside Client is “ClientID”, another is “ClientCode”.
-One column inside Case is “CaseID” and another is “ClientCode”, which corresponds to the ClientCode column in the previous table.
I need a file with output that looks like this CaseID+ClientID.
So, an example row from the “Client” table” could be ClientID = 123, ClientCode=999. An example row from the “Case table” could be CaseID=555, ClientCode=999. So, I need output of 555123 .
Scenario: 2 sets of data
Set 1 (200 records): firstname, lastname, address, city, phone
Set 2 (100 records): firstname, lastname, address, city, phone
I run a query using phone as criteria/condition (where xx.phone=yy.phone). I got 75 matches based on the phone numbers
However, if I deleted the phone numbers from set 2 data, used below query, the return result is only 45 matches. My question is what technique that I can use to optimize the result just based on criteria like first, last, and address.
select xx.firstname, xx.lastname, yy.Firstname, yy.Lastname, xx.address, yy.address, xx.city, yy.city, yy.phone
from set2 xx, set1 yy where
substring(soundex(xx.Firstname),0,3)=substring(soundex(yy.Firstname),0,3)
and substring(soundex(xx.lastname),0,4)=substring(soundex(yy.Lastname),0,4)
and substring(xx.address,1,7)= substring(yy.address,1,7)
and xx.city=yy.city;
Thank you

Hi, hope someone can help.
I have a table of employees and two sites. Most employees only do shifts at the one site but may occasionally work at the other site. What i want is the details of those who have worked at both sites.
for e.g.

2 Peter
3 John
Site 1
Mon John
Tue Peter
Wed John
Thu John
Fri Peter
Site 2
Mon Dave
Tue Dave
Wed Dave

In the trading (stock market) industry there is a practice of rolling up (merging) multiple trades into a single trade in an effort to save on ticket charges. The way this is done is performing a SUM() on the quantities and calculating an average price. (Average price is the SUM(Qty * Price) / SUM(Qty).
So, given :
Qty Price
20 $5
20 $10
You get:
40 $7.5 -- 20 + 20 and SUM(20 * $5, 20 * $10) / SUM(20 + 20)
Here is my dilema: If given a set of trades, I need to loop through them and check every combination to determine which one matches the expected rolled-up final trade. In other words,
If I know that the final trade is:
15 $10
And I have the following trades in my set:
TradeId Qty Price
1 10 $10
2 7 $20
3 5 $10
I need to check the roll-up of trades (1, 2), (1, 3), and (2, 3) and determine that it final trade was made by rolling up trades 1 and 3.
In the real situation, the number of trades that I need to check is not set to a specific number.
Any help would be appreciated. Cursors, temp tables, functions, recursive calls, .NET (I am running SQL 2005 so have access to CLR) are ALL acceptable solutions...
Here is a sample SQL code (table and data) to work with.
USE [tempdb]
DROP TABLE [Trades]
GO
CREATE TABLE [Trades] (
[TradeId] INT,
[Quantity] INT,
[Price] DECIMAL(6,2)
)
GO
-- need to find trades that rollup to quantity 30 and average price 7.5
INSERT INTO [Trades] VALUES (1, 10, 10)
INSERT INTO [Trades] VALUES (2, 10, 5.0)
INSERT INTO [Trades] VALUES (3, 25, 7.5)
INSERT INTO [Trades] VALUES (4, 10, 10.0)
INSERT INTO [Trades] VALUES (5, 2, 2.0)
INSERT INTO [Trades] VALUES (6, 10, 7.5)
SELECT
[TradeId],
[Quantity],
[Price],
[Quantity] * [Price] AS [MarketValue]
FROM
[Trades]
-- need to find the trades that roll up to quantity 30 with an average price of $7.5
-- Trades 2, 4, and 6 are the solution
SELECT
SUM([Quantity]) AS [TotalQuantity],
SUM([Quantity] * [Price]) / SUM([Quantity]) AS [AveragePrice]
FROM
[Trades]
WHERE
[TradeId] IN (2, 4, 6)
-- what I need to get back is the SET of rows that make up the rolled trade, so I want to see
SELECT
*
FROM
[Trades]
WHERE
[TradeId] IN (2, 4, 6)
Thank you for any and all help in this.
