Any Idea To Implement SCD Without SCD Component Of The SSIS

Dec 21, 2007

Hi All,
I would like to say thank you in advance for all your ideas. Here is my case i want to implement slowly changing dimension, i know that i can use SCD component of the SSIS, but because of performance issue i am thinking to use something else that can subtitute the SCD component, i want some idea from you guys if anyone has implemented before without Slowly Changing Dimension component.
If not, do you have any comment/suggestion to use the SCD component i mean if the worest comes and i use it, what draw backs does it has, for example interms of data size, performance. Note that i use Dedicated Server for the ETL in Production.

Thank you

Use Of A SSIS Variable Of Type “Object� Inside Script Component And Task Component

Mar 16, 2007

In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!

A Custom Component For Use As A VIEW In SSIS- Is It Possible To Create One MERGE Like Component With More Than 2 Inputs

Aug 13, 2007

Hi all
I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too.
Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting??
(I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)

How To Implement This In SSIS

May 22, 2006

Greetings SQL friends!

I have the following transact SQL code which I want to change to a set of SSIS components.



SELECT blah, blah

FROM PSTAGE..[stage_OFFER_PRICE_DIVIDEND] AS SOPD
LEFT OUTER JOIN PSTAGE..[stage_PRICE_GRP] AS SPG
ON SOPD.PRICE_GRP_ID = SPG.PRICE_GRP_ID
LEFT OUTER JOIN PSTAGE..[stage_type] AS TYP
ON TYP.TYPE_CD=SPG.PRICE_TYPE_TYPE4_CD
and TYP.TYPE_CL_CD = '0017'



I know I can join two data sets using a merge join (left join) but how do I combine a third merge join? Should I be doing this or should I just stick my code in a SQL Task instead?



Your help would be appreciated.

Some 'best Practice' On How To Implement SSIS

Dec 13, 2006

Hi,

We are planning for a DW solution based upon SQL Server 2005 EE. We will use a 64 bit machine for the Database engine and Analysis Services. Should we have seperate server for SSIS or should we use the same 64 bit box? If we go for a sepaerate server for SSIS should we use 32 bit or 64 bit ?

The primary datasources will be a new developed .NET application and a financial system based upon SQL Server 2000.

Every good advice/experiance is greatly appriciated!

Any Ideas To Implement This In SSIS?

Feb 26, 2008



Hi,

I need some help regarding SSIS.

I have a table containing a list of source table names to be transferred to destination.I need to pass each and every table name as a variable and based on the name of the variable I need to select data from source and insert into destination.The source and destinations are on 2 different servers.The source tables have different metadata (different column names and data types).Any help how to implement this would be greatly appreciated.


To be more clear I have List table which has below format

TABLE NAME
CUSTOMER
PRODUCT
INVENTORY

Customer , product, inventory are tables names. So my package should first go and collect the table name from LIST table and then transfer the Customer table data from Server A to Server B. This should be repeat untill all the tables listed in LIST table are transferred.

How To Implement Alter Database Implement Restrictions On SQL2K ?

Dec 28, 2007

Hi Guyz

it is taken from SQL2K5 SP2 readme.txt. Anyone have idea what to do to implement this ?
Our sp2 is failing. we suspect the above problem and researching it.we are running on default instance of SQL2K5 on win2003 ent sp2

"When you apply SP2, Setup upgrades system databases. If you have implemented restrictions on the ALTER DATABASE syntax, this upgrade may fail. Restrictions to ALTER DATABASE may include the following:

Explicitly denying the ALTER DATABASE statement.


A data definition language (DDL) trigger on ALTER DATABASE that rolls back the transaction containing the ALTER DATABASE statement.


If you have restrictions on ALTER DATABASE, and Setup fails to upgrade system databases to SP2, you must disable these restrictions and then re-run Setup."

thanks in advance.

How To Implement Restartability In Individual Mappings Of SSIS Packages?

Apr 30, 2007

restartability, is there any other tool option? like informatica

or

whether we have to implement through hand written query.

if query, then tell me how to do by taking scenarios like loading data from source sql table to target table.

suppose, in my target table, i have to load 100 records.

After loading 10 records,due to database downtime,or failure,

the loading stopped.

Either i have to truncate table or load it from 11th record.

Can u give me how to do this inside mapping

1)for table truncation

How Do You Implement Change Data Capture In SSIS Or SQL Server 2005?

Dec 3, 2007



Hi All,
I am now working on the design phase of my project, we are looking to implement Change Data Capture (CDC) but i need some help if you guys has implemented before using the SSIS 2005 componets. I am trying to use the Following:

Source---------Derived Column---------Lookup---------------Conditional Split (to split New records and Updated Records)-----------Destination. Respectively.
Lets make it clear, my source holds (Old records and newly added or Updated records), the Derived Column is to Derive new columns called Insert_Date and Update_Date. The Lookup i am Using is to look the Fact_Table(the Old Records) as Reference, and then based on this lookup i will split the records on timely based using the Conditional Split. My question is
1. Am i using the right components?
2. what consideration should i have to see to make it true (some Logics on the conditional split)?
3. Any script which helps in this strategy?
4. If you have a better idea please try to help me, i need you help badly.

Thank you,

Hi,

I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.

Package works from my computer. But when I execute it on the server as a SQL Agent job, I get







The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.  

I copied the mdb file to a folder on the server which my packages have no problem reading data from.

If-then-else-component In SSIS

Nov 23, 2007

Hi all,

i am not very experienced with the SSIS. I am just wondering if there is something like a "if-then-else"-componente like the foreach-component in SSIS.

I want to delete the values of all tables in one database. So I took a foreach-component and selected the smo-enumeration with all tables. I store the tablename in a variable and execute a sql-task with "delete table.." with the variable tablename as parameter. Now I want to delete all except one certain table. I would like to add a selection where the variable tablename is checked. If the tablename is this certain table, I don't want to execute the sql-command, else I want to excecute the delete-command.

Are there any suggestions?

Thank you very much

SSIS Script Component

Feb 6, 2008

I have just migrated a DTS 2000 package
as an SSIS package.
one of the features that failed to migrate, was a transformation
that , selected 2 colums of data with a stored procedure,
file name, and full path of filename,
Then the file name only was written to a txt file,
Then there was an ActiveX transformation task that used the other
column (full file path) to copy said file to another location (specified as a global str variable eg \127.0.0.1directory..etc)

Now my question is this, with SSIS script task
can i save the path name (2nd column) to a variable and then
using this variable copy the file to another location (global str variable) ?
Is there a CopyFile function like there is in ActiveX ?

And can i add this script task along with the DATA FLOW ?
because if i add it outside the DF , it will only (im assuming) copy the last line (path) into the variable...

SSIS Script Component

May 16, 2006

Dear all,

Such a pain, I know. Yesterday I did a couple of questions regarding transformation rows and very kindly I obtained answer (Thanks Jamie and Michael)
But now I face another stupid issue and is how to map source with destination columns inside Script Component Task.
On my Flat File Source I€™ve got defined thirteen columms (from Column0 till Column13); that€™s fine. And then, I€™ve got a sql table as destination with another names, of course€¦

Inputs and Outputs option from Script Component Editor leaf has been commited both (Input 0 and Output 0) but I wonder how the hell I€™m refer to them here:

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

** snippet of old code sql2 to migrate€¦

'If DTSSource("Col010") = "N" Then
' DTSDestination("ImpBase") = -1 * CDbl(DTSSource("Col011") / 100)
'Else
' DTSDestination("ImpBase") = CDbl(DTSSource("Col011") / 100)
'End I



.Net Script

If Row.Column10 = "N" Then
¿??????????????
End If

End Sub

Thanks a lot for your comments and thoughts,
Enric

XML Parser Component For SSIS?

Jul 6, 2006

Informatica has an XML parser component that allows me to read an xml file from a data source (Oracle Clob attribute in table in this case), parse it out in our mapping, and then transform the parsed date.

Does anyone know if SSIS has similar functionality?


Flow:

DataSource --> XML Parser --> Expression Component (Transform) --> DataTarget

SSIS SCRIPT COMPONENT

Oct 11, 2006

Hello,

My SSIS design: Source OLE DB -> Script Component -> Destination OLE DB

I have a script component that reads and proceeds each row in input. But I have no rows in output. How can you explain that ? with the viewer, I see the rows in input but in output, I have nothing after the script.
The script function: read the value of the ROW.column and flag like this :
ROW.columnout = TRUE (columnout is added in output columns)

What should I define at the component to retrieve the rows after the script component ?

Thanks !

Failing A SSIS Script Component

Mar 7, 2006

Hi

When there is an error in one of the rows a script component (in a child package) is processing I want to fail the child package and the parent package and not continue processing any rows.

How do I do this?

I have every thing in the script component in a try catch statment. This is the catch block

Catch ex As Exception

ErrorMsg = ex.Message + " " + RecordMsg + " Error on Column : " + ColumnMsg

ComponentMetaData.FireError(0, ex.Source, ErrorMsg, String.Empty, 0, False)

End Try

Also I have the FailPackageOnFailure and FailParentOnFailure properties set to true and the max errors value set to 0.

Any suggestions?

Thanks

Xml Ssis Data Flow Component?

Jul 2, 2007

There is a table with a column that contains Xml documents. For each record from my Data Flow Source, I want to pass in the Xml document and the node to interrogate, and return the value contained in the node. Like the Crm component, this is probably one I will have to write from scratch in C#, but I would like to avoid having to create the custom component if it already exists in the public arena.



Does anyone know of any Xml Ssis Data Flow Components that are downloadable for free?

SSIS: First Time Script Component

Nov 29, 2006

Hello,

I have a flat file that contains detail in each record as indicated below:


HEADER_ID, ATTRIB_A(1..10), ATTRIB_B(1..10), ATTRIB_C(1..10), etc.

The index of the attribute relates it to other attributes with the same index. It needs to look like this in the detail table:


HEADER_ID, ATTRIB_A1, ATTRIB_B1, ATTRIB_C1

HEADER_ID, ATTRIB_A2, ATTRIB_B2, ATTRIB_C2

I need to pivot these attributes into a detail table that relates back to the header information. Because of the number of these, I don't want to use the UNPIVOT Task because there are so many. I was hoping to move the complexity to a Script Component where I could read one line and transform it to a normalized state.

Can someone point me in the right direction?

Thanks.

SSIS Script Component To Concatenate Field

Jun 28, 2007

Is there a Data Flow Transromation in SSIS to take multiple columns from an excel sheet and concatinate them into one filed.

Ex:
'Strt-Address', 'City', 'State' into 'HomeAddress'.

I could dump them into a temp table and concatinate the fields and insert that into the destination but that seems like a waiste of using SSIS.

SSIS Buffer Problem - Lookup Component

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.

Comparing Current Row To Next Row Using SSIS Script Component

Jun 19, 2007

I'm trying to determine proper end date for measuring the effectiveness of my client's email campaigns. For each email address that received the campaign, I would like to determine a measurement end date. This date should be the lesser of 7 days from the Sent date or the date of the last email offer. This way, I prevent double-counting the revenue associated with each email campaign. Here's an example of what I'd like to see for each unique Sent Date and Email Address:



Sent Date Email Address Measurement End Date <<<< This is what I'm trying to derive with a script

2/22/2007 test@test.com 2/29/2007 <<<< 7 days from Sent Date

2/18/2007 test@test.com 2/22/2007 <<<< 4 days from Sent date due to the 2/22/2007 email

1/20/2007 test@test.com 1/27/2007 <<<< 7 days from Sent Date

etc.



If the input data stream is sorted by Email Address and descending Sent Date, then I need to be able to compare the Sent Date on the current record to the Sent Date on the next record (until the Email Address changes and then the process starts over).



I'm open to any solutions as this has really stumped me for awhile.
