Ssis Package Design To Load Only Rows Which Are Changed From Exisiting Rows.
Aug 17, 2007
Hi i tried designing a SSIS package which loads only those rows which were different from existing rows in the table , i need to timestamp the existing row with an inactive date when a update of that row is inserted (ex: same studentID )
and the newly inserted row with a insert time stamp
so as to indicate the new row as currently active, in short i need to maintain history and current rows in same table , i tried using slowly changing dimension but could not figure out, anyone experience or knowledge regarding the Data loads please respond.
example of Data would be like
exisiting data
StudentID Name AGE Sex ADDRESS INSERTTIME UPDATETIME
12 DDS 14 M XYZ ST 2/4/06 NULL
14 hgS 17 M ABC ST 3/4/07 NULL
New row to insert would be
12 DDS 15 M DFG ST 4/5/07
the data should reflect
StudentID Name AGE Sex ADDRESS INSERTTIME UPDATETIME
12 DDS 14 M XYZ ST 2/4/06 4/5/07
12 DDS 15 M DFG ST 4/5/07 NULL
14 hgS 17 M ABC ST 3/4/07 NULL
Please provide your input as much as you can even though it might not be a 100% solution.
Yet another question again on the issues with SSIS. I have a package now which is working fine.
The package consists of a control flow and i have 2 DF tasks which are unionall first and then saved into a sql server destination.
It's fine up to this point but i've just been notified that i would need to generate 2 files based on different values after i combined the data from 2 sql server DF tasks.
My question is how can i know the rows which are being saved on this sql server destination.
I have a primary key which is an autoincrement column.
Running this code on my PC via VS 2005 .Net version 2.0.50727 on the server (shown in IIS) Code is in ASP.NET 2.0 and is a VB.NET Console application SSIS 2005
Problem & Info:
I am bringing in an Excel file. I need to first strip out any non-detail rows such as the breaks you see with totals and what not. I should in the end have only detail rows left before I start moving them into my SQL Table. I'm not sure how to first strip this information out in SSIS specfically how down to the right component and how to actually code the component to do this based on my Excel file here: http://www.webfound.net/excelfile.xls
Then, I assume I just use a Flat File Source coponent or something to actually take the columns in the Excel and split into an OLE DB Datasource to shove each column into a corresponding column in my SQL Server Table. I have used a Flat File Source in the past to do so with a comma delimited txt file but never tried with an Excel.
Desired Help:
How to perform
1) stripping out all undesired rows 2) importing each column into sql table
Hi experts,I have been trying to limit the table rows in the following situation,any suggestions will be appreciated.we have table called tempTb has columns id, c_id, c_name, rating, datecolumns.id is an identity column.date is a datetime column, the rest are varchar datatype.Here is the table structure with sample data,idc_idc_nameratingdate1aoamer onli11/1/20022aoamer onli13/1/20023aoamer onli16/1/20024aoamer onli39/1/20025aoamer onli312/1/20026aoamer onli33/1/20037aoamer onli36/1/20038aoamer onli39/1/20039aoamer onli212/1/200310aoamer onli16/1/200411aoamer onli112/1/200412xyxabs yasd11/1/200213xyxabs yasd23/1/200214xyxabs yasd26/1/200215xyxabs yasd29/1/200216xyxabs yasd112/1/200217xyxabs yasd13/1/200318xyxabs yasd36/1/200319xyxabs yasd39/1/200320xyxabs yasd212/1/200321xyxabs yasd16/1/200422xyxabs yasd112/1/2004[color=blue]>From this table I need to select the rows with rating changes only,[/color]i.e if two or three consecutive rows have same rating only the firstrow should be selected.the selection should look like...idc_idc_nameratingdate1aoamer onli11/1/20024aoamer onli39/1/20029aoamer onli212/1/200310aoamer onli16/1/200412xyxabs yasd11/1/200213xyxabs yasd23/1/200216xyxabs yasd112/1/200218xyxabs yasd36/1/200320xyxabs yasd212/1/200321xyxabs yasd16/1/2004I was trying to do this by self-joining the table like....select t1.* from tempTb t1, tempTb t2where t1.id!=t2.id,t1.c_id=t2.c_id,t1.c_name=t2.c_name,t1.rating!=t2.rating.But this is generating cartesian products,I have tried some other combinations after where clause with date colmnwtc,but none seems to give the required result.so if anybody can guide me in the right direction I would appreciateit.Thanks alot,Remote
I have a ssis package which identifies duplicate records in access database. I have staged access database into sql sever and created ssis package. Now, I have final list of records which needs to be delete from access database and new records which are to be inserted into access database.
What do I need to do if I want to delete those duplicate records directly from access database using SSIS. I cannot truncate whole access database and reload. I just have to delete duplicate rows from access db and add new records.
I am copying a simple table from a Sql Server 2005 database to an *.sdf mobile database.
I am brand new to SSIS and I am probably doing something wrong. But after executing the SSIS package all the rows and all the fields are NULL in the destination database. I put a datagrid viewer between the OLE DB Source and the Sql Server compact edition destination and I can see the real data which is obviously not ALL NULL.
Does anyone have a clue as to why it would be doing this?
I am trying to create a stored proc that will update exactly one row. Simple. For insurance purposes, I want to create some logic that will rollback the entire transaction if more than one row is updated.
I know that I could force the primary key into the WHERE clause, but I was looking for some logic that will allow me to bypass that.
I have a SSIS package running well in production however sometimes the package will fail when the excel file contains more than 25000+ rows.
The SSIS package is run by SQL Server Agent and is set to run in 32bit mode.
I checked the data by loading in batches and all data loaded successfully. But the funny thing is when I run the same package on my local development PC using BIDS and the same data file. The package loads all 25000+ rows successfully.
Is there some setting that is preventing all rows loading in the server environment.
I am writing a db conversion for a retail grocery chain. This chain uses pricing zones to designate what stores get a certain price
Example: Cheetos Zone A: $2.79 Zone B: $2.89
The pricing data in the tables is listed by zone. However, the new product uses pricing by store.
Zone A contains stores 1,2,4,6,7.... Zone B contains stores 10,11,12,14.....
I need to be able to duplicate the rows in a manner that I can take the row containing a price for Zone A and duplicate it for each store in the zone. I have a table of stores with corresponding zones.
So I'm looking to go from:
Zone UPC Price A 1234500000 2.79 B 1234500000 2.89
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....
I have a table (represented by #Events) that holds modifications made to another table. I do have some control over the table structure and indexing. I want to pull all of the change records that were made between two dates.
The tricky part is to include the previous version of each record, which will usually be found prior to the start date in question.
The code that I have provided below works. So you can use it to easily see what should be returned. But it's very slow in production.
Any better method to pull this data together?
-- Production version of this table has 4.5 million rows (roughly 1,000 rows per day) -- Primary key is on L4Ident (clustered) -- nonclustered index on ProcessDate, LinkRL4 DROP TABLE dbo.#Events; DROP TABLE dbo.#Results; CREATE TABLE dbo.#Events ( L4Ident int IDENTITY(1,1) NOT NULL,
I created a simple type 1 slowly changing dimension, setting all the columns to "Changing Attibute". The first time I run the package it sees all rows as new and imports them into the dim as it should. Next time I run it put 100% of the rows into the "Changing Attribute Updates" and runs an update on all 90,000 rows - updating the rows to exactly what they were before
If I take the DIM and the Source in SQL and join on every row the join succeeds (meaning the rows match perfectly).
Shouldn't the SCD object just ignore the rows if they match? Or does it assume that ALL incoming rows are either new or changed? (if so why is there an output called "Unchanged Output"?). Is there some "gotcha" I am missing??
Need help, I am managing a Data Warehouse (80 G.B Database Size), I purge older than 6 months data from a table which has more than 140 Million rows on daily basis. The daily data load performance is degrading. The table has no clustered indexes (only non-clustered indexes).
Tried dropping and rebuilding the non-clustered indexes, didn't work.
One way to solve the problem is drop the non-clustered index, bcp out the data, truncate the table and bcp in the data and rebuild the non-clustered indexes. This is too risky and taking 14 hours to bcp out the data.
This was not the issue in SQL Server 6.5, because SQL 6.5 always insert new record indexes at the end of the heap link (heap = non-clustered indexes without clustered index). In contrast, SQL Server 7.0 first checks for available space in existing pages by using percent free space pages (this is where it is killing the performance ).
We are working on a DataWarehouse app. The DW has been loaded wiith transactional data from the start of September. and we want refresh the DW with a full load from the original source. This full load wil consist largely of the same records that we loaded initially in the DW but some records will be new and others will have changed.
During the load I want to direct input records NOT already in the DW to a "mods" table and ignore those input records that alreayd exist in the DW. Can SSIS help out with this task?
Help, is something wrong with my SL Server? I am unable to return any rows from all tables in all databases (user and system)on My SQL 7.0 SP2 machine. Whne i right click on the table in E.M and select design or open table i get no results. Does anyone know why this is happening? It did not always happen either. Thanks
JobRequirements (A) JobID int QualificationTypeID int
EmployeeQualifications (B) EmployeeID int QualificationTypeID int
Employee (C) EmployeeID int EmployeeName int
I need to return a list of all employees fit for a specific job ... The criteria is that only employees who have all the JobRequirements are returned. So if a job had 3 requirements and the employee had just 2 of those qualifications, they would not be returned. Likewise, the employee might have more qualifications than the job requires, but unless the employee has all the specific qualifications the job requires they are not included. If an employee has all the job qualifications plus they have extra qualifications then they should be returned...
How to only return those records where all the child records are present in the other table..

How to design at database level such a way so that when I implement a SQL query that returns one hundred thousand rows only display 25 rows at the client (Web page at a time). How can I accomplish this?
Once I display first 25 rows then how do I bring next 25 rows and so on. Can it be done via paging or there are other techniques. However I asked to design this in the database level. I am using MS SQL Server 2008. Front end Visual Studio 2010. I use C# for coding.
I am busy designing a ETL solution and have a question about how to design the packages.
We have over 30 source systems for different customers. We are building a WH that will combine all this data for analysis. The main issue is that these systems are always at different versions of the software. When a patch is released, it usually goes to one or two for a Beta process before it moves to the rest. These patches can affect the DB design, and we would want to be able to extract any new data as it comes available from the systems that have it.
Solution 1 - Package Versions The idea was to create the SSIS packages with a version number in their name. For each change, you would create a new version. The Batch control application that is being developed will store which system needs to use which version of the package.
Solution 2 - Multiple paths within a package This was to create a single package for each table, with a conditional split as the first task. The batch system will still provide which path the package needs to take with different Data Flow tasks containing the different column mappings.
Both have pros and cons, but was wondering if anyone has experience with this type of setup and which way worked best, or if there are any other options. Many Thanks Michael
I am in the process of designing a package for populating a Dimension table for my new data warehouse. I would like to discuss with you my proposed solution in the hope that some of you will be able to advise me on any mistakes that I have made so far.
I have 3 source tables which are used to populate my Dimension table (I will restrict each source table to a few columns to keep this simple).
Please note that I haven't included the start and end dates to keep this simple, but in my real solution, the Dimension table has many more columns.
The Meetings and Events tables contains hundreds of thousands of records so when my package is run, I should only retrieve information that has changed since the last time my Dimension table was populated. This is why I store the time stamps in my Dimension table.
So when my package runs, I get max(Meeting_Time_Stamp) and max(Event_Time_Stamp) from my Dimension table then retrieve all records from the source table where their timestamps are GREATER than the max values.
The problem is this :
If in the source system, an event is changed, the time stamp associated with that record will change value but the meeting record associated with that meeting will not have its time stamp changed.
How do I ensure that when my package is run, I retrieve all meeting and events information even if one hasn't changed?
Should I build a table made of IDs?! And if I do need to build a table made up of IDs, should I store this as a permanent table in my database or is there an SSIS data structure I can use to hold this information?
We are downloading 4 large (500mb) zip files in the package. Those come from 4 different FTP sites. Sometimes the FTP download on one of those fails.
Zip files contain images which need to be uploaded for existing listings. Each zip file is processed the exact same way. The question is how can I make the SSIS package so that each downloaded zip file can be processed immediately after the download - and not duplicating the processing logic?
I am new to SSIS. I need to transfer data from SQL Server 2005 Operational Database to SQL Server 2005 Report Database. The upload needs to work every night. There are few master tables and remaining are transactions tables.
I am planning to create 2 packages one for master tables and other for transactions tables. Is it the good approach?
Also few of transaction tables are heavy in terms of number of records. Will it better if i further break them in many packages?
I am using book "Microsoft SQL Server 2005 Integration Services Step by Step". Can you suggest any other good book?
I have a ssis package which runs daily. This ssis package has couple of execute sql tasks which load data for yesterday's transaction. Ex.
INSERT INTO Shipped (Div_Code, shipment_value, ship_l_id, shipped_qty, shipped_date, whse_code,
ord_id, ship_id, ship_l_ord_l_id, Created_date) select ord.DIV_CODE as div_code, ship.SHIPMENT_VALUE as shipment_value, ship_l.SHIP_L_ID as ship_l_id, ship_l.SHIPPED_QTY as shipped_qty, ship.SHIPPED_DATE as shipped_date, ship.WHSE_CODE as whse_code, ord.ORD_ID as ord_id, ship.SHIP_ID as ship_id, ship_l.ord_l_id as ship_l_ord_l_id, Getdate() as Created_date from SHIP ship, ORD ord, SHIP_L ship_l where ship.SHIPPED_DATE=(dateadd(day, -1, CONVERT(VARCHAR(10),GETDATE(),120))) and ship.WHSE_CODE='WPP' and ord.ORD_ID=ship.ORD_ID and ship.SHIP_ID=ship_l.SHIP_ID
All execute sql task has query like above query. and in some query we have date filter which loads data for yesterday. Ex. one query has ship.SHIPPED_DATE=(dateadd(day, -1, CONVERT(VARCHAR(10),GETDATE(),120))). some other query has ord.trans_date=(dateadd(day, -1, CONVERT(VARCHAR(10),GETDATE(),120))). this package runs daily through sql server job, so It loads data for yesterday. Now If i want to run for any particular date, How could we achieve from ssis?

I have created the tables and data into the database. And Now I need to prepare a Excel sheet to upload data into the these tables. How to prepare the Xlsx sheet and how to upload into database without using SSIS package.

I am having an interesting SSIS problem where the package fails to load with the following error message:
Code: 0xC0010018 Source: {BE86A659-AB44-403A-9C89-3524821879E0} Description: Error loading value "" DTS:Name="SqlStatementSource">"Select dbo.fnGetLastOpenExtract('" + @[User::in_ExtractName] + "') as eh_ID"" from node "DTS: PropertyExpression".
This very same package runs on our test server, but fails to even load on UAT server.
SSIS packages are the same on both Test and UAT servers (I compared not just dates and sizes - they are literally the same: byte-to-byte) DTExec version is 9.00.3042.00 on both servers. HKLMSOFTWAREMicrosoftMicrosoft SQL Server90DTSSetupVersion = 9.2.3042.00 on both machines.
This started to happen when the UAT machine was upgraded to Service Pack 2 of SQL Server 2005. Please note that the UAT server only runs SSIS packages and does not have SQL 2005 database engine installed. There is, however, an older installation of SQL Server 2000 on UAT machine (I am not sure if Test machine has it - will check tomorrow).
Any help is greatly appreciated.
Thanks,
Alex

I am using sql server 2005. I stuck out in a strange problem. I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
How can we handle transactions in SSIS 1. when some error/something happens during export and the # of rows are not exported fully to destination, how to rollback the transaction in SSIS.
I have a conditional split in an SSIS package - one split is where if rows are returned according to a specific rule, then insert those rows into to a Recordset Destinationm which points to a variable of Object type.
How I can use this variable to email fellow users. For example, what I would like is if ANY rows are returned to the Object variable (1 or more), then I would like to execute an email SP that we have on our server.
