Integration Services :: SSIS Lookup Not Working On Nvarchar Column Using FULL CACHE

Jul 30, 2015

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.

Integration Services :: Lookup With Full Cache Warning

Jul 29, 2015

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?

Integration Services :: Lookup Transformation - Used Destination Table For Reference Using Full Cache Mode

Jul 1, 2015

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.

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.

Integration Services :: Lookup Transform Partial Cache

Sep 6, 2010

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

Behavior Of SSIS Lookup Transform On Full Cache Setting With Low Computer Memory

Aug 9, 2007



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?

Integration Services :: SSIS Reads Nvarchar Values As Null When Excel Column Includes Decimal And String Values

Dec 9, 2013

I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?

CREATE TABLE [dbo].[Import_CustomerSales](
 [CustomerId] [nvarchar](50) NULL,
 [CustomeName] [nvarchar](50) NULL,
 [CustomerSales] [nvarchar](50) NULL

Lookup With Default Full Cache Option Yields No Results

Nov 20, 2007

I'm either missing something or this is a bug. I have a Lookup that finds no matches if I use the default option of full caching (everything on the Advanced tab unchecked). The lookup table is relatively small (15348 bytes) in only 544 rows. If I check only the Enable Memory Restriction box and eliminate caching, it works fine. I can also check the Enable Caching box and accept the default cache size of 5MB and it works fine. Anyone have any ideas? I'm running on Standard Edition, SP2.

Thanks!

Integration Services :: SSIS 2012 Lookup Transform Converts Date Field To String

Jul 30, 2015

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....

Integration Services :: ISNULL Not Working In Derived Column?

May 7, 2015

i have a derived column which contains the days of a month from 1 to 31

I have this expression for column 1:

(DT_R4)([1] == 4 ? 0.5 : ISNULL([1]) ? 0.0 : 1.0)

But the ISNULL function will not work. I am sure, there are some NULL Values in Column [1] but i get all the Time the value 1.0 back.

I need the Value 0 instead of NULL to calculate the days in an extra Column.

So that i have in the end a result column which have values for example: 4,5 or 5,5 .why ISNULL is not working?

Full Text Index Not Working When Populated From Nvarchar. Bug?

Jul 11, 2007

Hi, I was wondering if any SQL Server gurus out there could help me...

I have a table I'm trying to apply a full text catalog to, however no results are ever returned due to the text column being cataloged being of varbinary(max) that's being populated from a converted nvarchar(max) value.

To re-create the problem quickly...

If I populate the column via
CONVERT(varbinary(max), 'test text')
then there is no problem, I get results as expected.

However if I populate the column via
CONVERT(varbinary(max), CAST('test text' as nvarchar(max)))
no results are ever returned.

Is this a bug with SQL Server 2005 Full Text Indexing? I'm happily creating full text catalogs when an nvarchar is not getting converted into a varbinary.

I'm setting the Document Type column to '.html' (I've tried changing this to '.txt' in case it was a fault with the html ifilter but the problem persists so I believe I can rule this out).

The reason I need to convert an nvarchar to varbinary is that the table holds multi-lingual text and I'm adding a html meta tag <META NAME="MS.LOCALE" CONTENT="ES"> to the beginning in order for the full text indexing word breaker to select the correct language to catalog the text with. The aim being to provide more relevant searches in users native languages (I've read a few articles that describe this technique, but it's the first time I've tried to apply it).

Any pointers / suggestions would be greatly appreciated. Cheers,
Gavin.

Below is a T-SQL script you can run to demonstrate the effect I'm experiencing...

-- Create test database
CREATE DATABASE FullTextTest
GO
USE FullTextTest
GO

-- Create test data table
CREATE TABLE TestTable
(
pk UNIQUEIDENTIFIER NOT NULL CONSTRAINT tablePK PRIMARY KEY,
varbinarycol VARBINARY(MAX),
documentExtension VARCHAR(5),
)
GO

-- The below single entry WILL BE FOUND (the text source is being entered directly)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX),'<META NAME="MS.LOCALE" CONTENT="EN">test entry 1'), '.html')

-- The bellow two entries below WILL NOT BE FOUND (the text source is taken from an NVARCHAR(MAX) value)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 2' AS NVARCHAR(MAX))), '.html')
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 3' AS NVARCHAR(MAX))), '.html')
GO

-- Create the full text catalog
sp_fulltext_database 'enable'
GO
CREATE FULLTEXT CATALOG TEST AS DEFAULT
GO
CREATE FULLTEXT INDEX ON TestTable (varbinarycol TYPE COLUMN documentExtension LANGUAGE 1033)
KEY INDEX tablePK
GO

-- NOTE: You might need to give the catalog a chance to build before running the script below.

-- Now do a search that SHOULD RETURN 3 ROWS of data, but ONLY 1 ROW IS RETURNED
SELECT CAST(varbinarycol AS NVARCHAR(MAX)) FROM TestTable WHERE CONTAINS(varbinarycol, 'test')

Can You Cache A SSIS Lookup Component To Foxpro V7 With Parameterized Query?

Feb 24, 2006

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 ?

Integration Services :: Import Flat File Which Has Changing Column Order Using SSIS?

I have a flat with few columns

FirstName, lastName, Address
f1,l1,a1

I build my SSIS package based on the above file.But now i receive files with different columns order let say

lastName,FirstNamr,Address
l1,f1,a1
L2,f2,a2
or
Address,FirstName,LastName
a1,f1,l1
a2,f2,l2

every time i receive multiple files in different order and i have to remap all my mappings. These are just a few columns and i have like 20 columns and the order can potentially change any time. so every time i have build new packages remap them etc.

through normal c# code it pretty easy. I tried to add script here but the script also needs a source and mapping so there is also a mapping issue. Is there a better way to do this.
