Lookup Task Not Performing Correctly!
Apr 8, 2008
Hi, I'm using the lookup task to perform updates on some records and it seems to be working correctly but isn't making all updates. I have a case where there are 543 rows in my source connection, there are 436 of them that do not match the date column of the 543 in my destination table. It only updated 224 of them when it should have updated all 436? Does anyone know why it would only update this many instead of all? I also had another that only updated 18 out of 19 instead of all 19.
thanks,

I have to look up a mapping table and add 5 more columns from the mapping table if the look on the first column in the mapping table and corresponding column in source is successful.
But if there is no matching record in then mapping table I still need the record to pass through with NA values.
Please help?

Hello.
I have a car table, whose rows contain cars and their respective weight:
Ex: (1, 1000), (2,1100), (3, 900) etx.
I also have a car class table with the classes cars can fall into, based on a lower bound and an upper bound in which the car's weight must fit.
Ex: (Class1, 0, 999), (Class2, 1000, 1499), (Class3, 1500, 1999), etc.
I need to match each car to it's respective class. I've already search the database for post on this subject, but unfortunatelly my goal is yet to be reached. Can someone help?
Thanks in advance,

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
Description
StartDate
EndDate
Fact Table
id
measure1
measure2
TimeId
Description
Time Dimension
TimeId
Date
Day
Hour ...

Hello All,
I am tackling with unique request. I have to download the ".zip" files from the https and uncompress them. Now, the fetch process works fine when I am downloading the files. Using .net and .IO namespaces from system library.
Similarly after downloading I have to uncompress the files as these files are treated by compressed file folders by windows xp. I know it can be achieved by using the IO.compression class form system namespace.
But the only trouble here is IO.compression supports ".gz" and "Gzipstream.Uncompress" and I wonder how I would be able to get the ".zip" and "Zipstream.uncompress" done.
Thanks a million in all your help and advice. Also I appreciate for your time.
Regards
Sandesh

Hi,
I am having an issue when performing an FTP atsk to a remote site ( as opposed to internaly on a LAN )
I get the error "[Connection manager "FTP Connection Manager"] Error: An error occurred in the requested FTP operation. Detailed error description: 200 Type set to IMAGE. 200 command successful 550 permission denied . "
I can manually FTP to this site from my machine, using either a CMD window or Windows explorer. I can create folders, deposit files, delete files etc so I seem to have full control. This task works when testing on our local FTP server on the LAN. The "Test" connection works when configuring the connection to the remote site. It is just at runtime that the task fails.
Can anybody come up with any ideas why this may be ?
Thanks.

I have an Access 2.0 database that holds call data on a mapped drive. I am running MS SQL Server 2000. I can open it and view the records inside. I can even run the query below and get results, if I removed the CallDate and CallTime parameters.
SELECT CallDate, CallTime, Mid(CallRecordData, 68, 3) AS Extension, 'I' AS Direction, Mid(CallRecordData, 34, 11) AS Called,
Val(Mid(CallRecordData, 18, 2)) + Val(Mid(CallRecordData, 21, 2))/ 60 AS Minutes, Val(Mid(CallRecordData, 21, 2)) AS Seconds
FROM CallRecords
WHERE (CallDate = ?) AND (CallTime >= ?) AND (CallTime < ?) AND (Mid(CallRecordData, 30, 1) <> '9')
When I preview in the Transform Data Task, I get:
Package Error
Error Source: Microsoft JET Database Engine
Error Description: No value given for one or more required parameters.
When I look at the parameters, they are listed. I check their values, and they have the appropriate values (DateCalled, String, 07/14/2005) (StartTime, String, 06:30) (EndTime, String, 07:00)
When I run it in the build query or in Access with a linked table to the source, I can enter the values when asked for them and it works.
Thanks for any help you can provide.

This is the first time I've used SQL Server Integration Services, and I have it installed with SP2 applied on my local machine. I have created a Package, and dropped a Message Queue Task on it. I have pointed the Message Queue Connection Manager at a private queue on my machine. I have set the "Message" property to "Send message", I have changed the message type to "String Message" and entered "Test string" into the StringMessage property. When I execute the package (by clicking the "Start debugging" button on the toolbar), I get the following error message in the Execution Results:
[Message Queue Task] Error: An error occurred with the following error message: "The ServicedComponent being invoked is not correctly configured (Use regsvcs to re-register).".
There is no more diagnostic data that I can see in the Execution Results. Can anyone please explain to me how I can get this working?
Thanks!

Hi,
I've looked at so many examples on the web but I can't get my dataflow with lookup to work correctly. It just keeps inserting the records instead of updating them because they already exist. I know it's something simple but I've been trying to figure it out for the last 4 hours and am over my head. In the lookup I have 5 columns as available input and of course the matching lookup columns and selected 4 with lookup operation replace and tried add as new. It just keeps adding them to my destination table when they already exists. I can't figure out what i am doing wrong?
thanks,

Is there a way to set the Lookup task to be not case sensitive? For example, the lookup table has id 1, value 'ABCD'. The value that I'm using to lookup is 'abcd'. I cannot make it to return the id 1 unless I convert my lookup value to be all upper case.
And I don't want to use Fuzzy Lookup.
Thanks,

I have the following query in an ExecuteSQL Task:
Insert Into Table2
Select * From Table1 Where Column1Val = '4'
As you can see, I don't need any parameters so I havent configured any. Also, there should not be any result set so I shouldnt need to configure a resultset parameter.
Why is the above query failing with
Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly

I have an SSIS package that unpivots data - each row from the source becomes 20-24 rows in the destination db. In the dataflow it looks up some type-data IDs before inserting into the destination table. The whole process flies through the data at an incredible rate, however I find that the final commit on data insertion takes a very long time, and two of the lookup tasks remain yellow throughout. It appears that there may be a contention issue because the final table has FKs to those lookup tables.
In T-SQL it is possible to do SELECT..... WITH (NOLOCK), but when I modified the SQL statement of the lookup task by adding this clause, it caused an error "Incorrect syntax near the keywork 'with'."
Is there any way around this problem? THNX!

Hi
I am trying to use this painful new SSIS process. I basically need to use a lookup task to check to see whether a record exists or not. If not, then I need to insert the record. However, because this is treated as an error situation (which is stupid in itself), I get a problem when the number of records not found reach the MaximumErrorCount, and the rest of the package fails. Is there any other method of doing this type of thing, without simply increasing the MaximumErrorCounty to some ludicrous value. I could do this type of thing very very very easily when using DTS packages using the Data Driven Task, it seems so stupid that I can't perform the same kind of task using SSIS.
Any help would be appreciated
Thanks

Hello:
I'm attempting to use the lookup task and i'm running into an issue about incompatible datatypes.
The table that i'm referencing in the lookup has a field named DateCreated, and it's DataType is DateTime.
But when I hook it up to the Lookup Task, the lookup task thinks it's a DB_Timestamp, so i get an incompatible data type error.
What can i do?

Hi,
My SQL Server database is case in-sensitive.
I have a lookup task to join on varhar column. If the data is only case different such as 'DataModel' and 'Datamodle', lookup task consdiers them as different. Is there a way to set up lookup task as case insentive? I know I can work around it by converted them to upper case and compare them.

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.

We have a LKP table that we will use to decode incoming codes from multiple sales feeds to link to the relevant surrogate key for the ultimate dimension table.
The LKP table has a start date, end date and active row flag to track history of the codes.
This table in its entirety is required for the FULL history load but we will need a CURRENT version of the table containing only the ACTIVE rows for the DAILY incremental loading.
I am thinking of putting a standard view over the top of the LKP table to present only the ACTIVE rows rather than creating a 2nd table and reloading it each night. We don't have enterprise edition to use materialised views.
My question is, will the LKP cache populate as the SSIS packages begins, loading it with all the rows from the view, as it would if I used the 2nd physical table with only ACTIVE rows?

SSIS data flow transformation - Lookup task - best practice concerning Cachetype
I would like to know if there's any best practice concerning the CacheType property for the the Lookup task. Default value is "Full", but if the SSIS package is working with at lot of data, i.e. +10 mill. records from the OLE DB source to be handled through a variated numbers of data flow transformation tasks, it must have an impact memory usage if the lookup table also is a large table, i.e. +8 mill. records? When should I consider turning the property value to "none"

I try to convert a Procedure that join 8 tables with INNER AND OUTER JOIN, my understanding is that the Lookup task is the one to use and I should break these joins into smaller block, it takes a long time to load when I do this, since each of these tables had 10-40mill. rows and I have 8 tables to go thru, currently this Stored Procedure took 3-4min to run, by converting this to 8 Lookup tasks, it ran for 20min. has anyone run into this issue before and know a work around for this.

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.

The logic I am trying to recreate via SSIS is the following SQL statement:
insert into db3.dbo.targettable1 -- Target database table
(SiteC,
Objecte,
Attrib1)
select distinct ?,
?,
from ? -- Source database table
join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f
where f.FacID = ?)
where not exists (select * from dbo.targettable2 c -- Target database table
where c.Alias = ? and
c.FacID = ? and
c.CSetID = ?)
I have an OLE DB Source that consists of an expression to approximate the following portion of the Above Select statement:
Select ?,
from ? -- Source database table and
The package has 2 global variables User:CSetID and User::FacID whose scope is global to the package and whose values are set within a Foreach Loop Container outside of the Data Flow Task
I was trying to reference the 2 global variables within the Looup Transformation to recreate the following portion of the SQL statement.but encounter errors:
join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f
where f.FacID = ?)
In the Advanced Editor window of Lookup Transaction
select * from
(select * from [dbo].[targettable2 ]) as refTable
where [refTable].[Alias] = ? and [refTable].[FacID] = ? and
[refTable].[CSetID] = ?
Is there away to reference global variables in a Lookup Transformation that are set outside a Data Task Flow?

Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

The same package works fine against a similar test table with 150k rows.
http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.

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.

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?

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.

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.

OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks
John
