Date Lookup In SSIS
Nov 14, 2006How do I perform a date lookup in SSIS. I have a date with time component in it. This has to be looked-up with a table that contains only a date element.

View 6 RepliesWe are using lookup transformation in SSIS 2012. The lookup transformation queries a table with two date columns. When we hover the mouse over the two columns in the 'columns' tab of the lookup transformation editor, the two columns show as DT_WSTR instead of DT_DBDATE. This causes the SSIS package to fail due to data type mismatch.A similar abandoned thread is available at: URL....

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.

how i can add date using ssis or data tools 2012..My flat files had no date..den my instructor gave us a database where it has recordstartdate, recordenddate and currentdate.how i suppose to add date?
tell me the steps to how to do it?
I designed an SSIS package about 200 packages in one project.
the package extract from live to reporting server. some of my packages are very slow about 10 of them. strage enough the ones with more data number of rows run very fast. I'm using Source->Lookup->Conditional split->OLEDB Destination or OLDB Comand.
Can someone help me to found out what could be the problem. I'm very new in SSIS.
I'm trying to understand how to use SSIS variables within SQL commands and which Data Flow toolbox objects I can use for this. My simple package has a OLE DB Source object that returns the rows in a table. For the next operation, the output from the OLE DB Source is input into a Lookup data flow transformation where there is a select query that returns another value from a different table...
select bla from myTable where dbname = db_name()
The output is then passed on to an OLE DB Destination.
The above lookup query only works because, it so happens, that I could get a unique and correct result back filtered by current database name. However, due to other required changes, I now have introduce more 'where clauses'. I have all the necessary clause information in SSIS variables (iterated via a For Each loop). I would like do something like...
select bla from myTable where dbname = ? and bla_type = ?
However, there isn't a facility for Parameters in the Lookup object's 'use results of a SQL query'. I can see that I can use parameters in the OLE DB Source object by changing the 'data access mode' to SQL Query. However, it doesn't seem valid to join two OLE DB Source objects together in the data flow? I can't see any other suitable objects in the Data Flow toolbox. Ideally, I would be able to use Parameters in the Lookup object or some other object that would do the same job.
Thanks,

I am trying to run the Fuzzy Lookup on a SQL2K ref table using 2005 SSIS package and keep getting the following error:
[Fuzzy Lookup [2601]] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Cannot create a row of size 8061 which is greater than the allowable maximum of 8060.".
Regardless of the changes I make I cannot get this to work and it would make a huge difference if I could get it to run.
Can I create the FuzzyLookupIndex on a SQL2K database?
Any help or advice would be greatly appreciated.
Many thanks

Hi, I'm transferring lots of rows (each row is a problem) from an oltp database to a datawarehouse. These problems (rows) are transferred to the fact table. And a problem has attributes like status and logdate and solved_date (default null) and a sequence number. I also check every day for new problems in the source. Now the thing is ... I can write an SQL query to incrementally add new rows by using the sequence number as parameter. This is to lower querying time (BECAUSe the problem table has about 2.000.000 rows)
The Actual Question: I also need to write a query to update the tables in the Datawarehouse. For example when a status of a problem changes. When status changes from "unsolved" to "solved" it gets a date in the solved_date attribute. Now ... How can I write a query that goes fast through those 2000000 rows? Now I can't use the sequence_number because its not known when the problem gets solved. There is the fact that I run a query every day, so maybe I need to look at problems where a solved date is added on that day? Im just a novice in sql so maybe you guys know ways to do fast lookups in many rows? Or are there Data Flow tasks I can use? I was thinking about the slowly changing dimension but thats for dimensions right? :) So maybe any other tasks that are possible? I just need to put back on track because I cant find a good way to do this.
Using the lookup on a table, working with Haselden book, I plug into table on the
reference table tab and then press columns tab and get "Unspecified Error" Any thoughts?
Hi,
I am new to using SSIS. I need to know how can I retrieve the records in a Lookup component that cause an error to use them in a Data Transfer task. I created the error event handler but I don't know how to retrieve the records causing the error to use them in the Data Transfer task.
Thanks in advance for help!

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.
Hello there.
I've just upgraded from using DTS to SSIS. I've run through a few tutorials and am starting to use to the new ways of working.
There are however two task that I'm not really sure how to tackle, can someone suggest the best method in SSIS.
1) The destination table has many FK's. I'd like the package to check that the input data does not violate the FK's and use a default value for the columns where a violation occurs.
2) I need to increment a value in the package as a source column for use as the Primary Key field in the destination insert. It would be an added bonus if I could find out the maximum key used in the destination table already so that I can set my counter for this field at that value + 1.

Hi Everyone,
I'm building a package that is using the Fuzzy Lookup data flow item
and I'm receiving an error message that is troubling me!!!
"Fuzzy Lookup The length of input column is not equal to the length of
the reference column that it is being matched against"
If anyone can provide me any insight it would be greatly 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?
How would you do the following in SSIS?
SELECT a.TestID,
a.TestCode
FROM TableA a
WHERE UPPER(RTRIM(a.TestCode)) IN SELECT (SELECT UPPER(RTRIM(b.TestCode)) FROM TableB b)
Of course the above query is missing a few things but with ETL the where clause UPPER(RTRIM does not appear to be something that has an object or property that I can use in the Lookup.
Please correct and educate me.
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"
Hi All,
I have created a SSIS package with a Fuzzy lookup transformation.
It matches on 18 columns, looks for a 95 % match and has 50 variables that are passed through the transformation.
When I run the transformation it fails with the following error :-

I have tried all suggestions to fix this e.g. implement SQL Server 2005 service pack 2 - didn't fix it, up your virtual memory - didn't fix it.
Can anyone suggest what to do next ? Thx - Gary
Hi,
I have an example situation that seems like it should have a super easy solution, but my jobs keep failing.
Here we go. . .
I have a SQL Server 2005 table as my source in a data flow task.
This table contains raw data.
We'll call it FACT_Product_Raw - which contains a field called ProductType varchar(1)
Let's say that ProductType contains values of "A" or "B" or "C" - or for that matter, some null and garbage values
I have a lookup table, LOV_Product_Types
This table contains 3 fields that will transform my raw data table
We'll call these fields ProdTypeID smallint, ProdTypeRaw varchar(1) and ProdType smallint
It contains pairs such that A = 1, B = 2, and so on.
Here's what I want to do.
I want to ADD a field to FACT_Product_Raw that contains the "looked up" value from LOV_Product_Types.
Let's say that I want to add the ProdTypeID field to my _Raw table.
I have used the _Raw table as both my source and destination
It blows up every time.
Help.
Thanks,
David
I had this (what seems to be a) simple question asked today and I'm afraid I didn't like my answer. Does anyone know the proper answer to this one:
Any ideas on how I can constrain a lookup or merge join based on the dimension row's effective and expired dates so three criteria are needed as follows:
1. DataStagingSource.ModifyDate < DataWarehouseDimension.RowExpiredDate AND
2. DataStagingSource.ModifyDate >= DataWarehouseDimension.RowEffectiveDate AND
3. DataStagingSource.NaturalKey = DataWarehouseDimension.NaturalKey

I am trying to implement fuzzy lookup transaformation in my ssis package. However, I want to understand the basic logic behind this component. what is the algorithm that is used here and how it works (in a simple languange)Â ?

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 :

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.".

Any idea on what I should try next ?
I work in the healthcare area, and am handling the survey data ETL's. There are around 8 different survey areas and based on information received from them for the visit they reference, I want to pull in more info from our invoicing database. My idea is this:
1.)Â Pull in the flat file to an ODBC staging table
2.)Â Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.)Â First lookup the information needed on patientID, providerID, date of service, and billing location.
4.)Â For the surveys that didn't match on those 4 columns, try looking up based on patientID, date of service, and billing location (since I could be 99% sure this would still return the record I need).
5.) For the remaining surveys, lookup based just on patientID and date of service. These records will be flagged for manual review because clearly, if a patient has multiple appointments in the same day, this will be prone to error.
However, in trying to use only 3 of the columns in the lookup, I get the error saying basically that I need to utilize all 4. Is there a way around this, or is there an entirely different way I should be approaching this? The reason I thought cache transform was the answer is because I will need to run a different package for each lookup, as the data and logic between each survey will vary, but the invoice data "pool" will stay the same regardless.Â
I would like to know what happens when a very large reference data set for a lookup transform with full caching enabled is getting loaded during package execution and the computer memory runs out or is very low.
Does SSIS
a) give an out of memory error of some sort
b) resort to a no caching or partial caching mode
c) maintain the full caching mode but will switch to using the paging file(virtual memory).
I think it will resort to using the page file in which case the benefits of in memory lookups are lost and performance would suffer. If I cannot upgrade the memory or shrink the reference set somehow, i should switch that lookup task to use partial caching or no caching with an indexed lookup table. Would this make sense?
I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.

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

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.
