Reusing A Chached Lookup Component
May 10, 2006
Is it possible to reuse a Lookup component which is configured with Full chaching?
My requirement is as follows....
A input file have 2 columns called CurrentLocation and PreviousLocation. In the dataflow, values of these two columns needs to be replaced with values from a look up table called "Location".
In my package i have added two LookUp components which replaces values of CurrentLocation and PreviousLocation with the values available in the table "Location". Is there any way to reuse the cache of first lookup component for second column also?

Has anyone seen this strange behaviour?
I have a package which loads the fact data from Stage into Warehouse database. This packages normally handles early arriving facts. In that package I use lookup to check the dims which exists, and where they don't I populate the dimension and use the surrogate key to load the facts. This works fine.
I had a request to load 7 years worth of historical data. Instead of re-writing the package I took the package which handles early arriving facts and deleted the section which handles early arriving facts. I knew all the dimensions already exists and I don€™t want to hinder the performance when I load millions of rows. During testing I found something very interesting.
If you have configured error path in the lookup component and removed the error path later, the package will NOT fail (won't produce error) even if the lookup can't find matching values.
Correct Behaviour Example 1:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is not configured.
[4] From source we read 2 records, and the package will fail at lookup as it can't find Product Code 2.
Correct Behaviour Example 2:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is configured to go to RowCount.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and send the invalid record into RowCount.
Incorrect Behaviour Example 3:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Delete the configured error port from lookup.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and discard the other.
My understanding if the error port is NOT configured as shown in example 2, it should fail as shown in example 1.
Am I missing a point or is this suppose to be a correct behaviour or is it a bug?
Thanks

Hi,
i am doing a lookup to insert new records when the lookup has failed.
this works perfectly normally. however when my recordset has a name-column of type string with width 5 and my lookup-table has a name-column of char(20) the lookup will always fail and henc always inserting new records although the name "foo" should match.
is there a workaround for this, or do the compare-columns always have to be of the same type/length ?

Need to ask three questions regarding this component I am creating programatically:
1) How do you select "Modify the SQL statement" programatically.
2) How do you change the actual sql.
3) How do you add a parameter, also programatically.
I have manged to select "Enable memory restriction" by using
instance.SetComponentProperty("CacheType", 2);
but can't add a paramater and modify sql statement. Have used
instance.SetComponentProperty("SqlCommand", statement); and
instance.SetComponentProperty("SqlCommandParam", statement);
with no luck. Any ideas, have searched the web but found nothing.
Thanks.

Let's say I've a dimension with over 20 million rows. During my ETL, I need to replace the business keys with all the surrogate keys from this large dimension. The logic choice is to use the Lookup component. But does the Lookup component load all the 20 million rows into the memory? For a large dimension surrogate key lookup, what is the typical approach? TIA.

Hi,
Is there anyone out there develop raw file lookup component?
If not, is there anyway to read a raw file except using raw file source adapter?
Many Thanks,

i am using a lookup component to do a typical SCD. Compare the Natural keys and if they are the same -- REdirect the rows and do whatever, If not present -- means the Error Rows -- redirect and do whatever.
WHen I use the component to do a Historical Load (which means -- there are no rows are in the Destination table) and put the Memory to Partial Cache -- the Data Flow STalls after about 46,000 rows, it just doesnt complete after that. But the moment I switch it to Full Cache -- it flows -- But Partial is what I am supposed to be using -- keeping in mind -- the Incremental Loads. Why does the component stall ?
I had used Partial Cache in an earlier project -- with a 18 Million Row Table --(albeit for incremental load) and it worked fine (though is was slow -- but tleast it worked) -- but now I am trying to load just 300,000 rows but it stalls.
I am using a 2GB RAM machine -- and set the Memory to 750 MB/500 MB nothing worked
I tried two different machines -- same thing happened.
Any insight will be appreciated.

Hi,
I am getting this error in a Lookup component:
Error: 0xC020901E at Load_tblDelayfact, Lookup_DL_CODE [184]: Row yielded no match during lookup.
Error: 0xC0209029 at Load_tblDelayfact, Lookup_DL_CODE [184]: The "component "Lookup_DL_CODE" (184)" failed because error code 0xC020901E occurred, and the error row disposition on "output "Lookup Output" (186)" specifies failure on error. An error occurred on the specified object of the specified component.
Although the Lookup table is filled in with the following SELECT ststement:
SELECT DISTINCT DL_CODE, DL_COMMENT
FROM DL_Temp AS T1
WHERE NOT EXISTS(
SELECT * FROM DL_CODE AS T2
WHERE
T1.DL_CODE = T2.DL_CODE
AND
T1.DL_COMMENT = T2.DL_SENT_COMMENT
)
So there is no way that there is a record in DL_Temp (The data source) that does not exist in DL_CODE( the lookup table). Indded, I did serveral queries and tests to check that no such data exist and I found that no such record exists.
Please help me and tell me what can be the reason for this error. I used the same package on the same data yesterday and every thing went fine. Is that a bug that any of you faced before.
Thanks,
Aref

Hi,
Trying to get a particular SSIS is package working - while running the Package Installation wizard a package is reported with the following errors:
AcquireConnection method fails with error code 0xC0202009
Then Lookup fails validation and returns code 0xC020801C
The odd thing is the Lookup does not exist in the package, it did exist at one point but was deleted.
I have tried searching the XML and can't find any reference to the Lookup
Any suggestions appreciated...
Thanks,
John

Hi,
I am facing a problem with Lookup component in SSIS. I need to lookup from a transaction table for getting some info, But when im trying to implement the same, the Pre-Execute step itself got failed saying like,
€œ[DTS.Pipeline] Information: The buffer manager failed a memory allocation call for 524264 bytes, but was unable to swap out any buffers to relieve memory pressure. 9467 buffers were considered and 5956 were locked. Either not enough memory is available to the pipeline because not enough are installed, other processes were using it, or too many buffers are locked.
[Tracer [19717]] Error: A buffer could not be locked. The system is out of memory or the buffer manager has reached its quota.
[DTS.Pipeline] Error: component "Tracer" (19717) failed the pre-execute phase and returned error code 0xC020204B.€?
Component Tracer is the Look up. Tracer is having around 6.5 mil records. Is there any way to allocate more buffers thru buffer manager? Or is there any alternative to solve this problem? FYI, the hard disk free space is more than 250 GB.
Thanks in advance.

Hi all,
I recieve an error when I use the Lookup component in SSIS that reads:
Statement(s) could not be prepared.
I'm using a SQL 2005 DB as the source which runs into a lookup table and is use to compare records with an SQL 2000 Database. I've created connection managers successfully to both these databases. When trying to use the results of an SQL Query for the lookup to the SQL 2000 database (which is a linked server) and I try to map the columns, the error pops up and exits out of the lookup properties Window
The details to the error read:
Program Location:
at Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.Connections.SQLTaskConnectionOleDbClass.PrepareSQLStatement(String sql, Boolean bypassPrepare)
at Microsoft.DataTransformationServices.Design.DtsConnectionCommonControl.CheckSqlQuery()
I'm looking to use the results of this comparison to output in some form of a report. Ideas would be greatly appreciated!

Has anybody seen this issue already?
If you try to "enable memory restriction" from the Lookup component GUI you need to input both 32 and 64 bit size of maximum memory. However when clicking "OK" on the editor you get a message like :
TITLE: Microsoft Visual Studio
------------------------------
Error at Update Execution Logs [Lookup folder path 1 [4429]]: Failed to set property "MaxMemoryUsage64" on "component "Lookup folder path 1" (4429)".
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC0204006 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------
BUTTONS:
OK
------------------------------
You can only set the properties directly for mthe Properties window (F4).
I think this is a post SP1 bug in Visual studio designer...

I have a requirement to access a lookup table from within an SSIS Transform Script Component
The aim is to eliminate error characters from within the firstname, lastname, address etc. fields by doing a lookup of an ASCII code reference table and making an InStr() type comparison.
I cannot find a way of opening the reference data set from withing the transform.

I am using a lookup component in a SSIS data flow. The lookup is a select to a foxpro table. THe lookup works fine with full cache selected. I cannot get the lookup to work with a partial or no cache. I have the latest Foxpro OLE DB driver installed which I understand to support paramaterized queries. Has anyone had success with using cached lookup to Foxpro? Does anyone know how to set the lookup properties of sqlcommand and sqlcommandparam? I am unable to find any examples in BOL or on the web.
Here are some details. IF I go with "use a table or a view" option with the default cache query I get initialization errors
[lkp_lab_worst_value [6170]] Error: An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Visual FoxPro" Hresult: 0x80040E14 Description: "Command contains unrecognized phrase/keyword.".
In the advanced editor I see
SQLCommand set to
"select * from `kcf`"
and SQLCommandParam set to
"select * from
(select * from `kcf`) as refTable
where [refTable].[patkey] = ? and [refTable].[dayof_stay] = ? and [refTable].[modifier] = ? and [refTable].[kcf_code] = ? and [refTable].[source] = ? and [refTable].[kcf_time] = ?"
I believe the above error is because Foxpro V7 does not support the inner subselect . In addition the query contains CRLF without a continuation character (";").
If I remove the CRLF in the sqlcommandparam query, using the advanced editor, I get this design time error "OLE D error occurred while loading column metadata. Check the sqlcommand and sqlcommandparam properties". The designer requires both properties to be set, its unclear to me how the interact.
I cannot find any examples in BOL or on the web on how to set these 2 properties. Can someone give me a few guidelines?
I can get past the design errors by changing sqlcommandparam to a plain select that is VFP 7 compatible ( I removed the subselect and the square brackets):
select * from kcf as refTable where refTable.patkey = ? and refTable.dayof_stay = ? and refTable.modifier = ? and refTable.kcf_code = ? and refTable.source = ? and refTable.kcf_time = ?
But then I get a runtime error
[lkp_lab_worst_value [6170]] Error: An OLE DB error has occurred. Error code: 0x80040E46. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Visual FoxPro" Hresult: 0x80040E46 Description: "One or more accessor flags were invalid.".
[lkp_lab_worst_value [6170]] Error: OLE DB error occurred while binding parameters. Check SQLCommand and SqlCommandParam properties.
Any idea on what I should try next ?

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 all,
I am accessing one database a bunch of different times all throughout my code...in various functions and different web pages. Is there a a way to create an sqlconnection that I can access all the time, instead of constanting hardcoding which database to go to? I've tried putting the info in another file and just including it where I want the database to open, but I can't use <!-- #INCLUDE --> inside of the server scripts.
Can anyone help

Every time my asp.net app needs to open a connection, it tries to establish a new connection with the mssql server. I´ve already set the max pool size property in the connection string. After that, my app raises an "time out"error saying it couldn´t obtain a connection from the pool. The problem is that I have a lot of iddle connections. With the Enterprise Manager I can see the status of the connections. They´re all the same "awaiting command". How can I reuse this connections? I know that the connection string must be the same for all connections and it is. I´ve set it in the web.config file. If I remove the max pool size property from the connection string I get a lot, I mean A LOT of connections with the sql server. Any ideas?

Okay, so yes, I am new to SQL server...
I have this SP below, and I am trying to reuse the value returned by the Dateofplanningdate column so that I don't have to enter the code for each additional column I create. I have tried temp tables and derived tables with no luck.
REATE Proc CreateMasterSchedule
as
Select
dbo.[MOP_Planning Overview].warehouse,
dbo.[MOP_Planning Overview].[Item Number],
dbo.[MOP_Planning Overview].[Planning Date],
CAST (Convert (char(10),[Planning Date], 110)as DateTime)as DateofPlanningDate,
(case when dbo.[MOP_Planning Overview].[Order Category]='101' AND CAST (Convert (char(10),[Planning Date], 110)as DateTime)
<= (CAST (Convert (char(10),(dateadd(day, 8 - DATEPART(dw, dateadd(d,@@DATEFIRST-8,getdate())) ,getdate())-7),110) as DateTime)-1)then dbo.[MOP_Planning Overview].[Transaction Quantity - Basic U/M] else 0 end)as PriorInProc,
If I try to use DateofPlanningDate in the above case statement, I get the invalid column name error.
Basically, I just need a way to reuse the value returned by this column.
Can anyone help?

I was looking at a means of reusing dialogs.
The attempt I tried was looking up an existing dialog in the conversation_endpoints.
However on doing a scale test I would that the non blocking I was hoping wasn't happening. Even through I was giving each spid a new dialog by using a conversation_group_id related to the spid. I found that the following SQL was blocked by a transaction that contains a begin dialog. This suggests the locking on conversation_endpoints is too excessive.
select top 1 conversation_handle
from sys.conversation_endpoints ce
join sys.services s on s.service_id = ce.service_id
join sys.service_contracts c on c.service_contract_id = ce.service_contract_id
where s.name = 'jobStats'
and ce.far_service = 'jobStats'
and (ce.far_broker_instance = @targetBroker OR @targetBroker = 'CURRENT DATABASE')
and ce.state IN ('SO','CO')
and ce.is_initiator = 1
and (ce.conversation_group_id = @conversation_group_id )--or @conversation_group_id is null)
and c.name = @contractName

In the Package configurations wizard, I am trying to edit an existing configuration using the edit button. In the Configuration Filter, I get the list of several filters (the filters which were used for other packages). Whe I try to reuse an used filter, it is forcing me to set a new value and when I go back to SQL Server tables , I see the old value has got erased.
Can I not use an existing filter?. Do I need to use new filters for every new package?.
Thanks.

Hi,
I'm trying to test some queries in SQL analyser without reusing the query plan (already cached). I know that there is a way to avoid that but I don't remember right now. Another option would be to restart MS SQL service but I don't want to do that.
Any thoughts...?

Hi
I have a replicated table that has a trigger attached to the it. The trigger fires off a service broker message for inserts. Originally for every insert, I would begin a conversation, send, and end the conversation when target send an end conversation. Since replication process is only using a single spid, I would like to reuse 1 conversation. the following is what I have for the send procedure in the initiator. I check the conversation_endpoints for any open conversation, if it's null, I start a new conversation and send else just send with the existing conversation. Is there anything wrong with this code? What could cause the conversation on the initiator to be null if I never end the conversation on the initiator side? thanks
DECLARE @dialog_handle uniqueidentifier
select @dialog_handle = conversation_handle from sys.conversation_endpoints where state = 'CO'
IF @dialog_handle is NULL
BEGIN DIALOG CONVERSATION @dialog_handle
FROM SERVICE [initiator]
TO SERVICE 'target'
ON CONTRACT [portcontract];
SEND ON CONVERSATION @dialog_handle

Hi! I'm wondering why is my sys.conversation_endpoints table inserting a new row for each message i send even when i reuse conversations?
when i send the first message i get the first row in the sys.conversation_endpoints with a uniqueidentifier for the conversation_handle. this uniqueidentifier is then saved in the table which i query the next time i send a message to reuse the dialog conversation.
But even though it looks like the uniqueidentifier is reused i still get a new row for every message i send with a different conversation_handle?
this happens in both target and initator db.
I've tried to understand this by i don't.
Also for the moment i don't end conversations. But as i understand it this shouldn't matter.
Also the message successfully arives to the target and sys.transmission_queue is empty in both databases.
Neither queues have any error messages in them.
Thanx

I currently have multiple (parent and child) packages using the same config file. The config file has entries for connections to a number of systems. All of them are not used from the child packages. Hence, my child package throws an error when it tries to configure using the same config file because it can't find the extra connections in my connection collection.
Does anyone have any ideas on the best way to go about resolving this? Is multiple config files (one for each connection) the only way?

Hello,
I have a real heartache with runtime parameter interogation on my DB.
Sure I get the latest and greatest and sure I don't have to type in all those lovely parameter types..but...the hit I take on performance for making no less then 3 DB hits for each SqlAdapter is unreasonable!
So ...I like the idea of maybe calling it once for all my stored procs on application startup...and then maybe saving this in CacheObject.
My problem is that I can't see where you can even serialize a SqlParametersCollection or even for that matter assign it to a Command object. Can you cache a command object ?
LOL
I think I may just have to write some generic routine for creating and populating my command objects based on a key (type) and then use that to fetch my command.Update,
command.Insert and command.
I would like to use the new AsynchBlock to do the fetching of the stored proc parameters and then just pull them from the Cache object....put a file watch so that if the DB's change my params it re-pulls them again.
*nice*.....
Then I get the best of both worlds...caching...and no parameter writing...

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.
