I may have misunderstood how Lookupu works because it's not doing what I want.
From the OLTP datasource I have a long list of revenue items (from a SQL server database). I want to assign these to specific accounts as they are transferred into our accounting system. I have another table with a list of words to search for and which account they belong to.
For example if the OLTP source might be
Description - Amount
"Sales of cars"- "$20,000"
"Motorcycle sales" - "$15,000"
"Bike rentals" - "$2,000"
The account lookup table is like
Wordsearch - Account
"sale" - "ACCT_SAL"
"rental" - "ACCT_RENT"
So by looking up whether "wordsearch" is found in "desription" I should get an output of
ACCT_SAL - $20,000
ACCT_SAL - $15,000
ACCT_RENT - $2,000
Back in DTS I did this with an array and "If Instr" using VBScript in the Data Transformation Task. I'm sure there must be something in SSIS to do this - it should be something like a Fuzzy Lookup ?, but I'm drifting toward Script Component. Anyone got any ideas for SSIS
I've created a custom data flow tranformation and it isn't showing up in the Tool Box Items to be added under the Data Flow Items tab (right click on tool box, 'Choose Items...', then clicked Data Flow Items).
I have done the following:
signed the assembly, added to GAC, copied the dll to C:Program FilesMicrosoft SQL Server90DTSPipelineComponents.
It worked previously when I was just starting out, however now I cannot see it. What would cause it to not show up? Everything compiles fine. How would I determine how to fix it so that it shows up?
How would you do a log in a massive rows loading, I'm having problems because every row error(because of casting, format, lookup) in a transformation task is redirected to a text file as a log, this is ok when only exist one error by row, but in the case when I have two errors in the same row detected by diferents transformation tasks only the first one is reported to the text file, I have to wait to the second information load, after I correct the first error, to find the second one, I need to validate as many errors exists by row in the same load...
which component or which strategy can I use in a SSIS Packge to achieve this?
I can successfully get an Oracle sequence value using an "Execute SQL Task" transform. I need to, however, be able to get the same type of value from within a dataflow. I've tried the "OLE DB Command" and the "Lookup" Transform without any luck.
With the lookup transform I run into the following problem. First of all for those of you who know about the Oracle Sequence it just returns the next value from a sequence generator using "mysequence.NEXTVAL". The lookup transform won't just return a value without providing a link. So what I attempted to do was create a derived column with a value of "0" and use the following SQL command in my lookup ( SELECT mysequence.NEXTVAL, 0 AS DUMMY from DUAL). I then linked the derived column to the DUMMY column and it appeared to work. I was able to get the sequence. However, it appears to cache the value and so for each row the sequence is the same and doesn't increment.
I then tried to unsuccessfully play around with nocache but had strange errors about "not a valid sql statement".
I then also tried the OLE DB Command with a SQL statement "SELECT mysequence.NEXTVAL FROM DUAL" but couldn't get that to work.
Does anyone have any ideas or recommendations. Please keep in mind that I HAVE to get the NEXTVAL from Oracle as this is a mandatory requirement since the source is Oracle Applications ERP and I can't make up my own sequences in SSIS or update that sequence after the fact since many other applications could be using that sequence besides me.
I Can't reproduce the error if I run the package stand-alone.
I'm using the same lookup call (same table, etc.) in 2 packages that are running in parallel (called by a parent package).
[LKP_UnderwriterId [72283]] Error: An OLE DB error has occurred. Error code: 0x80040E05. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80040E05 Description: "Object was open.".
I am doing something really simple and it doesnt work, may be I am missing something, What I am trying to accomplish is to load a fact table using lookup transaformation, however my source data was different from the data in my dimension (or the datatype ) I had to use a data conversion task before my lookup , so the data flow is something like this source -> Data Conversion -> Lookup -> destination , I am getting an error at my lookup task where it says the "[Lookup [82]] Error: Row yielded no match during lookup". and then it just fails. I know for sure that there has to be matching data. donno what is it that I am missing.
I am totally new to SSIS. I need an example of how to use a Lookup transformation. Basd on that i need to lookup for some recs and delete records from transaction table. I have used the Execute SQL task for this and i am able to achive my requirement. But now i am using XML configurations for Connection Managers and for that very reason i dont want to hard code the catalog names(database names) inside my Execute SQL task.
Can any one suggest me how to do the same using a Lookup transformation or any other. Any suggestions will be greatly appreciated.
I have a Dataflow task which loads data from a flat file to a Fact table named Inventory , doing a dimensional Key lookup with DIMStores - which is the dimension table for stores information.
If I have some rows in the flatfile whose 'Store' column doesnt have a corresponsing key in the DIMStores table, I want to insert all these stores in to DIMStores table and then update the Inventory table accordingly ..
I have a question based on Lookup Transformation component. If using Lookup component, the data cannot be NULL for available columns mapping. How about I want to keep the NULL value like outer join instead of inner join? Is there any way to do since I have several Lookup components inside of my dataflow?
I'm trying to perform a lookup transformation. But the deal is, I have this one value that I am passing into the transformation, but I would like to gather all values that match the value I put in....does the lookup transformation do this? I tried it, and it appears as if it only returns one value for the one input. After the lookup, I have an access OLE DB destination setup...so I can capture all those values that corresponds to that one value I passed into the lookup. Does anyone have any ideas on how I can go about this?
This seems a bug to me. Or does anyone has a logical explanation that escapes me?
When in SSIS Designer Version 9.00.1399.00 I add output columns (numeric 4,0 ) to a scriptcomponent and fill them with valid numeric data in thescript I get a database error 'invalid number' when I use these columns in an OLE db Command-transformation . This errormessage disappears when I replaces those columns by a dataconversion to the datatype they originally have.
I have a question. I'm using a lookup table which contains descriptions for a field from one of my tables. I have added a lookup query that looks like this: SELECT STORE_DESRIP, BANNER, STORE_ID FROM `stores.txt` WHERE (STORE_ID = ?)
My main table (stagging) contains the store_id field. What I want to do is populate my destination fields (Store_descriptin and Banner) from the lookup table, based on the Store_id. I have written an ActiveX script that looks like this: Function Main() DTSDestination("Store_id") = DTSSource("store_id") DTSDestination("Store_description") = DTSLookup("storelookup").Execute(DTSSource("store_ id")).value Main = DTSTransformStat_OK End Function
I receive an error when I try to test this script. It complains about line 8, which is the line that contains the DTSLookup function. Does anyone have any ideas what I'm doing wrong?
The process I see here is that when it comes to populating the "Store_description" field is will look the lookup table and based on the store_id, pass the description back. I would also like to add another destination field into this script, but won't until I resolve this.
20 I need to do a translation of "group" to €ślocal group€?:
Customer
Group
Local Group
A
10
11
B
20
21 When a match is found, the group code should be replaced by the local group code ... but, when no match is found the group code should stay.
Is there any way to do this using Lookup ? I tried but when you set the error output to ignore it replaces the value that has no match with a NULL value. Maybe there is another way to get this done with or without the lookup component ?
I have a lookup transformation that retrieves a key for a certain column of values, in this case, a name. So, I go in to the lookup table with a name and come out with its key. I had it working and then I added new entries to the lookup table for a bunch of new names. Now, for some reason, I am not getting the matches for the new names. But I am still getting the matches for the names that existed before I added the new ones.
I'm wondering if the lookup transformation is using the old set of data and some how not picking up the new names. Do I have to trigger something in the lookup transformation to let it know that the lookup table data has changed?
I needed to lookup some table values based on a join of two fields...
I've configured the lookup transform to get the values via a SQL statement to minimize loading time.
However, when creating the relationships between the input columns and the lookup columns I receive following error: input column [BATCH_ID] has a datatype which cannot be joined on
I've checked both input and lookup columns, both are of type DT_R8... Both columns in the different tables do have the same datatypes
I've been going round in circles trying to understand what design I should use for a particular transformation/lookup problem I have. Would appreciate a few pointers.
On the data flow, I can create the data source easily with a SQL Query that returns 4 columns...
eg. myDb.dbo.Table1 Col1, Col2, Col3, Col4
The end result at the Destination is:-
myDb.dbo.Table2 Col1, Col5
Table1.Col1 maps directly to Table2.Col1 -- easy
Table2.Col5 is a result of a lookup query to different tables in the same db based on the value of Table1.Col1, Table1.Col2 & Table1.Col3.
I've already had problems with the Lookup component that forced me to give up using it because it wouldn't adequately support parameters. I was forced to use the Script component instead. However, this problem is a bit different because I don't need to try and reference variables as parameters and, instead, I need to use the values from the source query (Col1, Col2 & Col3).
There is one data flow task in the package. I have a column in the input set called "ID". The total number of rows in the input set is > 50000.
There is one table in the database which has the description for all the IDs. I need to get the "Description" value from the database for each row. The table contains nearly 12 lack records.
For that I am using lookup transformation. In lookup, I specified the query and column mapping and I got the new column "Description".
Here is the problem.
while running the package, the lookup is getting all the 12 lack rows from table and then it is matching the rows.
It is taking huge time.
Can any one suggest me how to improve the performance of this situation?
I just wanted to know if there is any way to Allow Null values while doing a lookup on a table in SSIS.
Let me elaborate the situation...
I have a flat file source that has a field called 'code'. I want to lookup in a code table to see if the code in the file is a valid code but the flat file may contain a NULL value as a 'code' (i.e. zero length string which treated as NULL by my package).
My problem is, the SSIS package tries to search for the NULL in the table and the lookup fails and an error is logged as per the business logic but actually NULL is also an acceptable value and the error should not be logged.
I tried inserting a NULL value in the lookup column but that doesn't work. I am not sure but I think I have read somewhere that two null values cannot be compared for equality. I cannot use conditional split to check the null value because I have to use a large number of lookups and a conditional split everywhere will mess up the things.
I have an input flow with dates and fields like this :
ID BEGINNING_DATE ENDING_DATE
1 12/01/2006 12/16/2006
and a reference table like this:
ID PRICE BEGINNING_PRICE_DATE ENDING_PRICE_DATE
1 400 11/28/2006 12/03/2006
1 500 12/03/2006 12/06/2006
1 600 12/06/2006 12/09/2006
I have to get the intersection periods between the two tables joining on ID. I would like to have this result flow :
ID BEGINNING_DATE ENDING_DATE PRICE
1 12/01/2006 12/03/2006 400
1 12/03/2006 12/06/2006 500
1 12/06/2006 12/09/2006 600
I'm using a lookup transformation and modifying the SQL instruction in advanced tab like this:
select * from (select * from [dbo].[Price]) as refTable where [refTable].[ID] = ? and (? between [refTable].[BEGINNING_PRICE_DATE] and [refTable].[ENDING_PRICE_DATE] or ? between [refTable].[BEGINNING_PRICE_DATE] and [refTable].[ENDING_PRICE_DATE] or ([refTable].[BEGINNING_PRICE_DATE] between ? and ? and [refTable].[ENDING_PRICE_DATE] between ? and ?))
My problem is that the transformation looks for only one matching element and outputs 0 or 1 row per input row... In that case the 3 rows of my lookup table are matching with the row in my input table, but I have only the first one.
I used to use Lookup Transformation for my SSIS, now I am having problem and cannot find the problem. I have my source table, one lookup to join source column to my lookup column as L1. I then have another lookup to join L1 to L2, and will show L2. It seems not working. I used to have source to join several lookup and get different Li, not this one. Any help?
Has anyone else noticed this? I want to be able to use a paremter in my reference table of my Lookup Transformation. I couldn't find any way for the dialog to accept SQL with a parameter so I checked on MSDN How to: Implement a Lookup Using the Lookup Transformation and sure enough in the article is says to click on the Parameter button. I don't have a Parameters button on this dialog. Error? Is this possible?
6. In the Lookup Transformation Editor, on the Reference Table tab, select a connection manager in the Connection manager list, and then do one of the following:
Click Use a table or a view, and then select either a data source view, a data source reference, or an OLE DB connection manager.
Click Use results of an SQL query, and then build a query in the SQL Command window, or click Build Query to build a query using the graphical tools that the Query Builder provides. Alternatively, click Browse to import an SQL statement from a file. If the query includes parameters, click Parameters to map parameters to variables. For more information, see How to: Map Query Parameters to Variables in Data Flow Components. To validate the SQL query, click Parse Query. To view a sample of the data that the query returns, click Preview.
I found that sometimes when the cache is filled up, the performance drops significantly. Anyone knows the caching strategy behind the Lookup Transformation? If it's LRU or FIFO for example, I may have to sort the input based on FK to get better performance. If it's frequency based then sort might not help. Cheers,
I have to perform a lookup in a table based on a query like:
"... where ? = [RefTable].fieldID and ? between [RefTable].AnotherFieldValue and [RefTable].AThirdFieldValue"
So, SSIS has put the CacheType to none. As I really need to speed up the job I want to set the CacheType to partial (full isn't an option due to the custom query I use here).
But here it comes: when using partial CacheType, one has to set the cache size manually - and I really don't know what value I should assign to it - is there a guideline on this topic?
I work on a Win2003 server platform with sql server 2005 - 2 processors - 2Gb Ram - enough disc space
I am trying to use a lookup in a package and check for some conditions. On the advanced tab, I am trying to modify the condition from = to <=. But the same doesnt work when the target is on oracle, but the same works fine on SQL Server and DB2.
Error at Data Flow ACH Validate File and Header Info [Lookup ACH Batch Number [506]]: input column "ID" (571) and reference column named "BANKBATCHNBR" have incompatible data types.
"Lookup ACH Batch Number" is the name of the lookup transformation. input column "ID" has a string data type. reference column "BANKBATCHNBR" has a varchar(50) data type. can someone please tell me how i should go about debugging this validation error? thanks.
Hi Gurus, I have a Dataflow Task which has an OLE DB Source calling a SP with parameters (?, ?). Then this OLE DB Source is conencted to a Lookup Transform which also calls a SP but on a different database. I am unable to figure out how to pass parameters in a Look up Transform. In the 'Use Results of an SQL Query' pane of Lookup Transform:
Code SnippetEXEC GetMonthlyDataExtract 4, 2007
( I am passing month and year values) this works ok.
But when I chage to
Code SnippetEXEC GetMonthlyDataExtract ?, ?
It says EXEC not supported. Also I can not figure out how to configure parameters since 'Reference Table' Tab of the Lookup Transform does not have any option where we can attach variables to parameters. Also I am interested to map parameters to variables not to input columns. If mention if that is not possible or any other alternative.
My lookup data is in a csv file, not a table. Is there a way to get the Lookup transformation to use the csv file as the source 'table'? Obviously the alternative is to load the file into a SQL Server table and use that, but I want to keep it simple if possible.
