Integration Services :: SSIS Cache Transform Lookup With Multiple Indexes
Jan 16, 2013
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.) Pull in the flat file to an ODBC staging table
2.) Cache all invoice records that fall between the MIN(Date of Service) and MAX(Date of Service) from the staging table.
3.) First lookup the information needed on patientID, providerID, date of service, and billing location.
4.) 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.
I've a simple lookup transform in SSIS 2008 (R2). I've created it with a full cache and it worked fine. When i switch to partial cache, it will give me this error:
-------------------------------------------------------------------------------------------------- TITLE: Package Validation Error ------------------------------ Package Validation Error ------------------------------ ADDITIONAL INFORMATION: Error at DFT_AdventureWorks [Lookup [411]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[Code] ....
I've created a OLE source with the following query :
SELECT SalesOrderID, OrderDate, CustomerID FROM Sales.SalesOrderHeader
And this will flow into the lookup transform and this has the following lookup reference query:
SELECT CustomerID, AccountNumber FROM Sales.Customer WHERE CustomerID % 7 <>0
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 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 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 am using a lookup and full cache, occasionally i get this warning:[Lookup [150]] Warning: The component "Lookup" (150) encountered duplicate reference key values when caching reference data. This error occurs in Full Cache mode only. Either remove the duplicate key values, or change the cache mode to PARTIAL or NO_CACHE. Now I know it is only a warning but it is highlighting a real issue.Is there a way of capturing that this has happened?
My source has 2.2 million of records. I'm performing the incremental load.In the lookup transformation i used the destination table for the reference using Full cache mode.For the first time package executed successfully but when i executed the package second time, Suddenly Package hangs while running.Than i truncate the data from the destination table and restart the SQL Server Services.After doing all this i executed package again and it worked but when i executed package second time, again package hangs up .I have 8GB RAM and i5 2.5 GHz Processor laptop.
I have a Pivot Transform in SSIS (2005) working perfectly, EXCEPT for that the first column of the output (the date) repeats for each of the following columns, which are themselves falling into the correct column, but not on the same line for a particular date as the others. Snipet of result from Data Viewer is:
We are using the cache transformation in our project , while doing the cache transformation our disk space goes to 0 MB free and SSIS package execution not completes even after 3 hr..Initially we have around 34 GB free space on C: drive .Our server configuration is 64 RAM. We are caching the data from table which contains around 21 million records.We changed the path in properties (“BLOPTempStoragePath”,”BufferTempStoragePath”) of Data Flow task of SSIS in which we are using Cache Transformation.
In my current project i have a requirement to assign value of an aggregate transform to a variable. But i need to accomplish it without using a script task.
I have two records in the source with information ID, RevisionID, Description, Region
There are two lookup files one with ID,Description amd other with ID, Region
I wish to update my two source records with performing lookup with these two files.To get the correct description and region data. How to do this in ssis DFT.
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) ?
Please indulge my ignorance, as I have only been using SSIS for a couple of weeks. I'm trying to create a data warehouse using two input tables. A column needs to be added to one table by using a lookup into the second table. SSIS seems to handle the "no matches" and "single match" cases perfectly. I can't for the life of me figure out how to properly handle multiple matches. SSIS defaults to the first match, but I need to compute the "best" match.
I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
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 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

I need to do something like this in SSIS:From one SQL table I need to get some id values, I am using a simple sql query:Select ID from Identifier where value is not null.I've got this result:As a final result I need to generate and set a variable in SSIS with the final value:
@var = '198','120','ACP','120','PQU'
Which I need to use later in a odbc expression.How can I do this in SSIS?
I have an SSIS package in VS 2010 that uses flat files to load database tables. I would like to check for the flat files existing before continuing to run the package. The flat files each have their own connection manager. I was wondering if I could use the connection managers to determine the file names instead of creating a Script Task and hard-coding each of the file names to check.
I have created an SSIS package which processes daily financial information to a sql server database. These processes are to be outputted to excel spreadsheets to a readable report format for management to review. Some of these reports are laid out in a way that is not just tabular output but requires customized placement of data on an excel spreadsheet to specific cells.
I am able to place an initial resultset of a query output from the database in a tabular excel template through SSIS but the issue is at the end of that placement in the spreadsheet I am required to place another output below that tabular output in a different format from the initial output which I have shown below.
I need to export multiple tables from a database to multiple csv files (one for each table).
Rather than use SSIS and have multiple OLEDB sources and destinations (one for each table), is there a way to have a generic package that will export all the tables in the database ?
One way I can see is to use BCP in a loop - with the loop powered by a select statement that links to something like sys.tables etc, (or another table that i prepped with just the tables I want if I dont want them all).
i.e I would use a stored procedure that uses BCP (called via XPcmdShell) - so not via SSIS - although I could wrap up the whole thing in SSIS - but there is no realy need.
How do I know when its the right time to use the Cache Connection Manager? I understand that Full Cache mode eliminates the need to query the lookup table for every row.
Is the Cache Connection Manager intended for use by multiple packages that need access to the same lookup data?
I need to import multiple flat files with different formats into different tables of the sql server database and not able to figure out the best way out in ssis to do so...
What are the possible methods in ssis to do so and if possible the process which can be dynamic as file names or columns might change in future.
We are building a dataload application where parameters are store in a table. And there are multiple packages for each load.There is a column IsChecked column if it is 1 then only the child package should execute.Created a master package. In which i have taken execute SQL task in that storing a results in variable and based on the result the child package should execute. But In executesql task i selected result set as full result set. I am getting the below error.
[Execute SQL Task] Error: Executing the query "SELECT isnull(ID ,0) AS ID FROM DataLoadParameter..." failed with the following error: "The type of the value (DBNull) being assigned to variable "User::LoadValue" differs from the current variable type (Int32). Variables may not change type during execution. Variable types are strict, except for variables of type Object.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.
Can SSIS be used to created these two tables? (one without description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.
I have multiple xml data file in a directory say C:XMLData abc1.xml, abc2.xml, abc3.xml etc.
Need to loop through each file in ssis with Foreach loop container, and get the file name say abc1, and load the data of abc1.xml to abc1 table in sql server DB.
Next iteration will pick up the abc2.xml and find the abc2 table in sql server DB then insert the data in abc2 table.
While each iteration, xml source should also point each xsd file correspondingly.
Tables are already created in DB
I solved my problem up to getting the file name from ech iteration and assigned file name to variable, in oledb destination data access mode I select Table or view name variable, then corresponding table will get selected for data insertation.
Just wanted to know how can I read each xsd file for each xml data files while iteration.
we can assign one parameter value for each excecution of [SSISDB].[catalog].[set_object_parameter_value] by calling this catalog procedure..
Example: If I have 5 parameters in SSIS package ,to assign a value to those 5 parameters at run time should I call this [SSISDB].[catalog].[set_object_parameter_value] procedure 5 times ? or is there a way we can pass all the 5 parameters at 1 time .
1. Wondering if there is a way to pass multiple parameters in a single execution (for instance to pass XML string values ??) 2.What are the options to pass multiple parameter values to ssis package through stored procedure.?

We run std 2008 r2. I'm looking at the files this transform is complaining about. They seem to be named appropriately. The customerid folders don't exist when this runs. I'm going to put one in place to see if that is the problem.
The errors i'm getting are...
[Export Column [22]] Error: The file name "c:usersmyuserid heprojectnamecustomeridafilename.doc" is not valid. The file name is a device or contains invalid characters. [Export Column [22]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Export Column" (22)" failed because error code 0xC020207F occurred,
and the error row disposition on "input column "FILENAME" (29)" specifies failure on error. An error occurred on the specified object of the specified component.
There may be error messages posted before this with more information about the failure.
