Hi All
I've created an SSIS package that loads data from source to destination, using Lookup and conditional Split to check New rows and changed rows for one table.
Now I want to take this father by loading data for multible table more that 100. I did it in T-SQL using dynamic sql and cursor.
How can I achive this using SSIS.
We are in the process of converting our existing incremental loads from DTS to SSIS.
Currently we get all the data for the past month into temp tables in the warehouse, compare with key fields add the new rows and update changed rows. All this is done using Execute SQL task.
Is there a better way to implement the incremental logic using SSIS any new objects that be used to avoid too much SQL codes? Performance is very important and we do a lot of aggregation after the load for the reports to run faster so that we can meet customer SLA's.
We have around 20 tables that needs to be loaded 4 have large amount of data between 20 and 40 million rows out of which we will be brining over around 100 thousand during each incremental run. The other tables have less than 100,000 rows so does not hurt truncating and reloading the entire table.
Any assistance is appreciated.
Thanks!
Hi everyone. I'm trying to figure out how to run an incremental load into a Staging table.
At this point I'm not trying to Conditional Split it between "New" and "Changed" records... just the load.
The logic in my head says that after each load, you can take the most recent "modified" date/time and store that in an incremental load table. That way, next time you run an incremental load, you just have to look up that "modified" date/time, and only load the source records with a "modified" date/time later than the record in your incremental load table. Does that plan sound feasible?
I think so far my problem is that my source is on an ADO.NET connection, and my incremental load table is on my SQL Server. So when I do my load from the ADO.NET database, I cannot read the data from the incremental load table.
Is my logic flawed?
Any help would be appreciated.
Thank you very much!
Hi,
Is there any way to maintain history of data while incremental load without using the Slowly changing dimension(SCD) concept?
I am attempting to perform an incremental load, inserting new rows and updating existing rows. I am using a lookup and everything works fine, except when it is the first load of the destination table. As there are no records in the table at all, the lookup fails. I thought of using a rowcount - if the count variable is zero load everything from temporary table to load table, otherwise perform lookup and incremental load.
Can anyone help?
I required query for Incremental Load of CDC using Query
View 1 Replies View RelatedHi all,
i have a fact table which loads through package,when
i m trying to load this table by running the package,i m truncating the
fact table and loading the fresh data,instaed of this without
truncating the fact table i have to implement the incremental logic in
this.
For this i can use SCD or Conditional split,but problem
here is i have many source tables to load this fact table,so its
very difficult to trace the changes in different source tables.
can any one help me out in this??????
We need to implement incremental load in database. A sample scenario is, there is a view (INCOMEVW) which is build on top of a query like
CREATE VIEW INCOMEVW
AS
SELECT CLIENTID,COUNTRYNAME,SUM(OUTPUT.INCOME) AS INCOME
(SELECT EOCLIENT_ID AS CLIENTID,EOCOUNTRYNAME AS COUNTRYNAME,EOINCOME AS INCOME FROM EOCLIENT C INNER JOIN EOCOUNTRY CT ON
C.COUNTRYCODE=CT.COUNTRYCODE
[code]...
This is a sample view. As of now there is a full load happening from the source(select * from INCOMEVW) and loads to target table tbl_Income.We need to pick only the delta and load to the target table using a staging. The challenge is,
1) If we get the delta(Insert,update or deleted rows in the source tables EOCLIENT,EOCOUNTRY,ENCLIENT,ENCOUNTRY, how to load the incremental to
single target table tbl_Income.
2) How to do the Sum operation with group by in incremental load?
3) We are planning to have a daily incremental load and thinking to create the same table structure as source with Date and Flag column to identify
the date and whether that source row is an Insert or Update or Delete with the flag. But not sure how to frame something like this view and load to single target with Sum operations.
I have a table in Server A and it has 5 columns. One is Address & ID, CreateDatetime,..
I need to transfer data from this table from Server A to server B for a report pupose. The Address column in this table has some places two address in the table. I am giving ex below
Address
Houston, Dallas
Redmond
Sacramento
New Jersey, New York
I want to avoid the rows where address are two Houston, Dallas & New Jersey, NewYork to the destination table in server B and need to do incremental loads.
how to proceed with this?
The version we are using is Sql Server standard edition 2008r2
We have build a powerpivotmodel that uses a couple of datasources. The user extracts on monthly base an excel file with 20 samples (randomly) from the model to check some aspects of the input. He can put Yes or No into a column if he agrees or not and fill in a remark field. Next this excel file is loaded back into the powerpivot model (in a nightly batch) and the Yes/No field and the remark field are added to the original data. If the user refreshes his excel sample file from the pivot, the remark and YN field will be filled with the values he added. So far so good. One moth later when he extracts the file for a new month a problem arises. Since the excel file only has data for the new month, when the PP-model is reloaded the data for the previous month will be lost. So we need some sort of incremental load for the excel file. Is that possible and is this the best way to handle this situation?

View 4 Replies View RelatedWe are designing a Staging layer to handle incremental load. I want to start with a simple scenario to design the staging.
In the source database There are two tables ex, tbl_Department, tbl_Employee. Both this table is loading a single table at destination database ex, tbl_EmployeRecord.
The query which is loading tbl_EmployeRecord is, SELECT EMPID,EMPNAME,DEPTNAME FROM tbl_Department D INNER JOIN tbl_Employee E ON D.DEPARTMENTID=E.DEPARTMENTID.
Now, we need to identify incremental load in tbl_Department, tbl_Employee and store it in staging and load only the incremental load to the destination.
The columns of the tables are,
tbl_Department : DEPARTMENTID,DEPTNAME
tbl_Employee : EMPID,EMPNAME,DEPARTMENTID
tbl_EmployeRecord : EMPID,EMPNAME,DEPTNAME
How to design the staging for this to handle Insert, Update and Delete.
I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
I inherited an SSIS package that is rather simple. It grabs data from a SQL Query and then loads it into a SQL table. The first step of this process TRUNCATES the destination table and then reloads for the current year. This table has over a million rows and the DB SOURCE that we are pulling from is not in our domain, so one can imagine how long this takes.
This process is working fine, (given the 45 minutes it takes to repopulate data in the DESTINATION table), but what I really need is a way to load only the rows that are NEW and UPDATED. I would also need functionality to DELETE the rows that have been removed (sounds like a MERGE, right?).I tried using MERGE and MERGE JOIN transformations but these transformations seem to be different from the T-SQL MERGE statement. MERGE seems like a slow UNION and MERGE JOIN only seems to work with SELECTS.
I am looking to load data incrementally from staging to spectrum database.
Master = Staging table
Detail = Spectrum table
On below logic
.If record from Detail (Spectrum table) is null
then do insert the record into Spectrum table
set status_flag to 'A' for active
else do update the record (replace all old values with new values)
set status_flag to 'A' for active
end-if
· If record from Master (Staging table) is null
then do soft delete
set status_flag to 'D' for delete
end-if
Hello,
I have a big problem and i'm not able to find any hint on the Network.
I have a window2000 pc, VS2005,II5 and SQLServer 2005(dev edition)
I created an SSIS Package (query to DB and the result is loaded into an Excel file) that works fine.
I imported the dtsx file inside my "Stored Packages".
I would like to load and run the package programmatically on a Remote Scenario using the web services.
I created a solution with web service and web page that invoke the web service.
When my code execute:
Microsoft.SqlServer.Dts.Runtime.Application.LoadFromDtsServer(packagePath, ".", Nothing)
I got the Error:
Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The package failed to load due to error 0xC0011008 "Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.
The error message doesn't help so much and there is nothing on the www to give me and advice....
Is it a SSIS problem???
Thank you for any help!!

I have an SSIS package that imports data. It's working fine except I've been told that the Load_Date field needs to have the same date for each record in the table (the table gets truncated and then loaded each time the SSIS package runs). I created the table with a default of getdate() for Load_Date but I've been told not to do it that way and to have a variable in SSIS to populate Load_Date to make sure it's the same for every record. I've set up a variable in SSIS. I made it a datetime type of variable. It defaults the value to the current date (at that time) but doesn't let me change it to getdate(). I think the way to use the variable is to have a derived columns step that uses the variable Load_Date and then in mappings, set the column equal to the variable. But how do I set the variable equal to getdate() so it can be used for each row?
Thanks
Has anyone attempted to perform a load test with SSIS? I am trying to saturate(100% processor utilization) a HP integrity rx4640 server with 60GB of ram and 4 processors, windows 2003 and Sql server 2005 in order to to build a sizing document?
Hi,
I have a little experience with SSIS (but a lot with DTS) and none with CRM 3.0.
Is it possible to use SSIS to import flat files into CRM 3.0 ?
And how ?
I read something that CRM 3.0 uses SQL server 2000. Should I upgrade it SQL server 2005 ?
Any suggestion where to read about this ?
Thanks in advance

Hi,
How to extract and Load Data using ADO.NET in SSIS.i hope to extract data we have DataReader source .but how to load (Insert) data with ADO.NET ?.and is ADO.Net quicker than OLEDB ?
Thanks

I loaded a vchar column using script trans (SSIS doesn't support XML data types :/) to format the XML data properly. Since the XML data in the vchar column was not encoded, when I try to alter the vchar column to xml after the table is loaded it fails. I assume this is because the parser is having trouble with the content of the data within the xml tags.
This is how I coded the XML rather than using a xml method. "true" places the element end tag.
newXML += FormatElement("CONFERENCE") _
+ FormatElement("NAME") + ConvertToESC(RTrim(Mid(Row.activity, 1, 34))) _
+ FormatElement("NAME", True) _
+ FormatElement("START_DATE") + ConvertToESC(RTrim(Mid(Row.activity, 35, 8))) _
+ FormatElement("START_DATE", True) _
+ FormatElement("END_DATE") + ConvertToESC(RTrim(Mid(Row.activity, 43, 8))) _
+ FormatElement("END_DATE", True) _
+ FormatElement("CONFERENCE", True)
My question is, can I either load the data, using T-SQL, into an XML data type from a vchar column or is there a way to alter the type from vchar to xml without encountering the following parsing error?
Msg 9421, Level 16, State 1, Line 1
XML parsing: line 1, character 64, illegal name character
Thanks for any suggestions!

Greetings all,
After moving all my packages to a new server, win2K3, SQL2k5, non of the SSIS packages run. They all ran fine on the other server.
The error is
"2006-03-07 13:09:38 - ! [LOG] Step 1 of job 'ExportXML' (0x4E0C7495EFE4034FA6EF94B7C7F77262) cannot be run because the SSIS subsystem failed to load. The job has been suspended"
These packages ran perfectly on the old system.
Running the package manually, using DTExec or from the Saved Packages tree in SQL is fine.
Package is saved in SQL.
Any ideas?
Especially interested in the CodePageConvert.
Installing the .msi just creates a project folder in my Visual Studio directory. I'm unclear how to get from this point to being able to choose this component from my Toolbox items in SSIS. There was a readme file that talked about gacutil.exe and .snk files that was a above my head.
Can anyone dumb it down for me?
Hi
I am new to SSIS and am looking to load XML files (with a DTD definition) into tables via a SSIS package. I have created a XML task and am able to load the XML and output it to file. I have also stripped out the DTD definition and am able through a dataflow using XML source an OLE db Destination load and map the XML to table sin my DB. But have no idea how to get the data in when it has a DTD definition included. I either want to put each file into a row in a table then query it. Or from the SSIS package input the relevant info into a set of staging tables or the real tables.
Any help/pointers would be appreciated.
HI All,
I have Uzip Files to be downloaded From ftp.companyname.com, the zip files get updated everyday thus i have to download the newly added files, the Zip file has got 13 text Files within it, the issue is:
1. how do i download it for the new zip file only, the zip files are shown below, i am trying using FTP Task, but need more info or other alternative.
2. (Optional) How do i UnZip it and and take the text files and then load them to sql server 2005, each text file has to be loaded to sql server tables.
3. How do i automate it, i mean every time i run the package (on Job based) it has to look the new file only, see the zip file below to understand what i am saying about.

03/04/2008 04:49PM 3,238,121 CompanyName_2008-03-03.zip
As you can see the Zip file names are the blues color, they are added at different time, when you browse the ftp.companyname.com you will get the blue color files, thus what i need is to download only the current Zip file (i mean i have to downLoad only the newly added Zip file (recent one)). Thus the SSIS Task has to go to this FTP server and look the newly added zip file. (Optional) if possible, After that i have Unzip it b/se i have 13 text files there, and then Load them to Sql Server 2005.
Please get help on this, the deadline is near by time, if possible try as soon as possible, I would like to say Thank you for every help you do and try.
Thanks,
I am trying to load a SQL 2005 table that consists of two guid values in two fields. I have a flat file in tab delimited form that has guid values as strings to load into the table. I used a flat file source module in SSIS; which then goes to a Data Conversion module that takes the flat file and does a conversion to type unique indentifier [DT_GUID]; this goes to a OLE DB destination which is a SQL 2005 table that has no records and only those two fields. I get this following primary error:
[Data Conversion [498]] Error: Data conversion failed while converting column "Column 0" (373) to column "Copy of Column 0" (511). The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
An example of the two values in the .txt flat file source:
84d92cbb-4b4b-435b-8d8a-789ea930283c 328340cd-85fd-4210-8d82-000024093d7c
Any ideas what may be causing this? This should be pretty straight forward load. But it is guid which seems to always cause cast issues.
I want to create a SSIS package as follows
Conditions
If there are about 100 records in text file, if there is an error at 43 and at 67 record respectively , it should capture 43 and 67 record in failure folder and remaining 98 records , should be processed
1) Successful record into table and move the success record from the folder
to new path say( Success folder) (98 records to table)
2) Unsuccessful records to new path (Failure folder) (2 lines )
3) Error message to capture the failed records and store them in another folder(Error log) (2 line failure information)
While writing the 3rd condition to error log table , it has to point out the record which is failed for what reason, say it may be due to invalid data type for column 10 for 43 record, and incorrect syntax error at 67 record.
I have created a package that loads data . I need advice on a quik way to schedule this baby .

Hey,
I seem somehow stuck in some Script Task problems in SSIS on a x64-environment which has SP2 installed already.
If I'm running the package in 32-bit mode, I'm continuously getting the following error
"Warning: Precompiled script failed to load. Attempting to recompile. For more information, see the Microsoft Knowledge Base article, KB931846 (http://go.microsoft.com/fwlink/?LinkId=81885)."
on one of the package's scripts --
the given links advises to install SP2... what a useless hint.
And if I switch the project to run in Run64BitRuntime=True , another script tasks complains
"ScriptTask_78888010d24c477ea7c8d69f4f5568a5 is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
-- whatever that might mean...
Maybe I should add that the packages were running in 32-bit mode for the last 12 months now. Without any problems like that.
Those effects are occuring since we put SP2 onto the server...
Any comments on this topic? Similar experiences? Maybe yet some solutions too?

Hello !
Please, this is an urgent call; May be someone issued the sama probleb I do :
When I'm trying to import a XML file, that contains diffgram, using the XML Source task in SSIS, I choose an Inline Schema Option - everything goes well...the tables and columns are displayed, and the Import task into a Database's table succeds.
The problem is that , it doesn't load any data into the table, though there are plenty .
Hello,
I don't have a specific problem, I'm looking about resources because this is the tipical case when something is working but I don't know why ..
On particularly I have to load and run a dtsx package from a window application and the package is located on the server.
I decided to use .NET Remoting.
I developed my "Remotable Object" which contains:
package = Microsoft.SqlServer.Dts.Runtime.Application.LoadFromDtsServer()
package.Execute()
etc....etc...
The window application calls the Remotable object, call the specific method and the package is loaded and run successfully.
When I studied the .NET Remoting there is also Server that expose the Remotable Object.
In this case the Server is SSIS Service but I would like to know witch port is used, which method( singlecall or singleton ) is used and so on!
where I can find this info?Someone knows some resource to advice?? or I'm working with SSIS not on a remote way?
Thankx
