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?

Hi can anybody give me a simple example to check exact match word using sql sever Ex: my word is like this : welcome to sql sever2005 Now i want to find server how it is possible? I tried like this select * from test where content like %server% . but is gives me possible result. But i dont want like this if i have an exact match with that key word then only i want possitive result. Actually there is no word with server, i'm having only server2005 . So how can I get it?
I am getting my source data from another system am storing the SaleAmount of each product in a field the data type of which is [decimal](12, 2).
For some products I am getting an exact match (upto 2 decimal places) as compared with my source data BUT for some other products the value before the decimal places is correct but the 2 digits after the decimal place does not match with the source data :confused:
Even if this sounds stupid, can you please guide me. Am i missing some very basic and common sense thing?
Could anyone help of how to match the exact characters in a data field in SQL 2005 Developer. For example, if one has a password "GooD", then when he or she enters "GOOD", "good", etc, the database will not match the password. And he or she must enter the exact characters, which is "GooD". 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:
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.
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.
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.
I have a report that displays many duplicate rows where all fields in several rows are exact duplicates. I would like to know how to make it so that the entire row does not show up if it is an exact duplicate of another row. Any ideas? Thanks.
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?
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?

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.
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.
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).
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.
same colored items are grouped by GroupID. Each group contains ItemID, Qty and rate. How can i compare IteamID, Qty and Rate of each group with other group's ItemID, Qty and rate? OR How can i get number of groups with same ItemID, Qty and rate?
I want to have a select that will pull the following information out with count = the number of rows that have matching data in data4
ID data1 count 1 535 2 2 325 2 3 654 1 4 765 1
Right now I am using a VB script to loop thru get the current data4 value then using SELECT COUNT(data1) AS count FROM tbl_toolerrors WHERE data4 = {data4 value currently looking at}
Of course this take a bunch of trips to database and I think there should be a way to do it. I was thinking of a nested SQL querry like
Select data1, data2, ID, data3, (select count ...) Order by data1
I would like have your help about a query. In fact, I have a query to retrieve the rows for specific ID. Like that:
SELECT * FROM TblUser u WHERE EXISTS
(
SELECT *
FROM TblScore s
WHERE s.FKIDUser = PKIDUser
)
With this query, I retrieve all users for which ones there are some scores. Now, I need to get only users with specific score. In the table TblScore, there is a column ScoreValue. This column contains a value between 1 and 15
I would like to retrieve the users having score equal to 2,4 and 6 I could add a where clause like that: "and scorevalue in (2,4,6)" But I want only users having these and only these scores, not less, not more.
So if an user has the following scores: 2,4,6,8, I don't want to retrieve it If an user has the following scores: 2;4, I don't want to retrieve it. If an user has the following scores: 2,4,6, I want it.
I have a common requirement in numerous SSIS processes to take my main input data set and to remove all rows from it that match a second input data set on a given key and output this as the main output. I also want to output (as a second output) all the rows from the main input data set that did match on the given key. However, I don't want to merge in data from the second input, nor am I interested in rows from the second input data set that have no match in the main input.
E.g. If I have the following data:
Main input: Key Name --- ---- 1 Steve 2 Jamie 3 Donald
Given a many to one relationship between an incoming flat file and a SQL table, is there a way to have explode the number of rows in the data stream?
Basically, I have a flat file and for every row in it there are one or more related rows in a SQL table that need to be looked up to provide a descriptive column and then passed down stream to the next transform. When I tried the lookup transform, SSIS only passed the descriptive column from the first matched row.
Is there any way that I can drag and drop rows in SQL Server Studio Management Express? Every time I open a table, I want to move a row by just dragging and dropping but it can't be done.
Hi i have a look up from one table to another now i know that some data is set to null in one table and this is the row am doing the lookup on. I'd like the package to run as normal and still catch these failing rows. Is this possible to do ?.
I was trying to set the Configure Error output but i can't get my failing rows to be set to the text file.. the package runs ok But am getting the same problem again in another lookup as am using the same data to do a lookup again and its causing me the same problem.
Our division has approximately 300 employees. We have an annual shift bid where seniority is calculated using Date of Hire. If 2 or more employees share the same Date of Hire then we fall back to Date of Application. Currently the SSRS report does a very simple query and shows all the employees in order of their Date of Hire. If they match then it sorts the matching Date of Hire entries alphabetically by the employee name. It then becomes the task of the scheduler to locatethe entries with the same Date of Hire and manually look up the employees' dates of applications then sort them accordingly and re-write the report.
Goal: Convert the manual process into an automatic process by modifying the current SSRS report. Data: The dataset is "DivDir" which contains the following fields: "EmpName", "DofHire", & "AppDate".
EmpName DofHire AppDate Adam ...... 12/2/1996 11/15/1996 Bob ..... .... 1/16/1997 12/27/1996 Charlie ....... 1/16/1997 12/12/1996 Dan ...... ... 4/11/2001 3/22/2001
In the above example I want the SSRS report to list the employees in this order: Adam, Charlie, Bob, Dan.How do I do this programmatically using SSRS?
Maybe someone here can help me out: I have a Kimball type II dimension, where i track changes in a hierarchy. Each row has a RowStartDate and RowEndDate property to indicate from when to when a certain row should be used.
Now i want to load facts to that table. So each fact will have a certain date associated with it that i can use to lookup the right Id (a certain SourceId can have mulitiple integer Ids when there are historic changes) and then load the facts.
Is there a building block I can use for that? I could do this with SQL scripts but the client would prefer to have as much as possible done in SSIS. The Lookup transformation will only let me specify an equal (inner join where A=B) join, but i need equal for one column (SourceId) and then >= and <= (RowStart and RowEnd) to find the right row version.
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.
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.
