Multiple Sources && Destinations...
Apr 13, 2006
Hello,
I am working on a typical data conversion project where we are migrating data from an old data model to a new data model, using SSIS. Both the DBs are in SQL.
Now we have a situation where say there are 25 source tables and 20 odd target tables.
For transporting data, we are using OLEDB Source & OLEDB Destination transforms. However, each transform maps to one view or one table. As a result, the Data Flow is really messed up with 45+ transforms in it. Is there an elegant way of doing this ? With say just one datasource or maybe fewer transforms?
Thanks,
Satya

I have around 120 tables. I am using script component to pull the values from oracle stored procedures. I do not want to create 120 source & desitinations in my dataflow. Please advice how can this be possible with one script component and one oledb destination.
I noticed I can add mutiple outputs in 1 script component which makes the script component to work like a dataset (container of different recordsets (tables) ), if I am correct. Can this be redirected to an dynamic oledb connection.

I have a dynamic flat file I need to import to a table (in the same format as the file). The problem, I'm realizing, is that dynamic column mappings are a pain with SSIS. I have to know the format of the flat file ahead of time, which I won't.
What are my options here? Can package configurations help with this?

When I set up a Flat File, Excel, or XML source, I have to specify the complete file name, in particular the folder where the file exists. I would like to specify the location dynamically, via a variable or property -- but how?

Until there's an Integration Services 2.0, what custom components would you most like to see examples of? The documentation team is starting work on the 2nd Web refresh of Books Online and SQL Server samples, anticipated for release around April, and may be able to incorporate some requests as samples or BOL topics.

Can you have more then one OLD DB desination connected to the slowly changing task for the NEW OUTPUT scenario. I know I can have more then one if they have different outputs...like New Output for one and the other have fixed attrib output or unchanged output.
I have a query that gets data but I want to insert that data in 2 different tables at the same time. I can not re-query to get the data since it may change the data I get the second time I query.
So if I have a query that returns a data set how can I insert into 2 diff tables?

I want to run multiple DTS packages which export data into text files.
There is only one Data Source ..and multiple destinations.
When i write a code for this in VB ,for each Package i need to define the source connectioninividually. Can't i use the same Source connection which i used for the first package in the subsequent packages?

Hi,
The further i get with doing my current SSIS package the more i am starting to wonder about best practices and performance.
My current package loops through CSV files in a specified location and extracts events from these files. Each file contains multiple events which are a mixture of different types. Depending on the event there are a different number of comma seperated values. In the package i firstly set each event to one column seperated by a comma delimeter. I then create an array for the event which is split by the delimeter. In a script i weed out all elements of the array that are common to all events and set the remaining events to another array. After some processing i come to my conditional split transformation which splits the processing of each event based on the EventID. This is where i'm having doubts on whether i have approched the package correctly. There are approximately 60 different events so each one of these has a seperate pipeline to process the remaining parameters in the array and output them to the destination table. The destination table is differnet for each ID. Is it viable to have this amount conditions and paths when creating the pacakge and is this likely to have any detrimental effect on performance. Is there possibly another way that i could approach this problem?
Many thanks, i hope that made sense.

Hello Friends,
I need suggestion/help
I have to build a package using SSIS and the requirement is like this,
First I have to check the data source type(3 types for now)
then I have to select a query for each different source from a table (basically the connection string and query changes for each query)
and load the data into the dimension and fact tables.
I am not able to get the full picture of how I am going to achieve this, there is little complication to this one of the 3 sources has 15 servers from where i have to extract data
Hope I am clear enough
Appreciate any suggestions
Thank you

Not sure if this is possible, here is the scope:
I have a vb program that calls a sp. My vb program connects to DataSource1, Catalog1 and to DataSource2, Catalog2. My sp resides in Catalog1 using a table from catalog1 and a table from catalog2.
Is this possible to do?

OK I have 4 differant Data Sources... One being a count of one DB, another count of another DB, another count of another and then another process from a script component. Each source returns 1 row of data with 1 column each except the Script Component. It returns 3 columns... Now I need to take each of the row's returned and combine them to a single row (line) and inset them into another table just as one single eatry. I am using a Union All and when it runs I see the 4 Data Sources say 1 Row... But after it hits the Union All it does 4 rows... What am I doing wrong or am I using the wrong component? Please if anyone can help that would be wonderful.

I'm thinking aboug using Service Broker to aggregate transactions from 12 remote SQL Servers to a central SQL Server. Service Broker is new to me, so I don't know what the proper setup would be.
We have five different kinds of transactions that can be sent from any of the remote servers. These remote servers truly are remote, connecting to the central server over a WAN. We don't want problems with one server to interfere with any other server. We also don't want problems with one kind of transaction to interfere with the processing of any other kind of transaction.
If were only talking about one remote server, I'm guessing I'd want to create 5 different services - one for each kind of transaction. Does that mean I'd also need to create 5 different routes on both the remote server and the central server?
And how would I scale this out to a dozen remote servers? Can I stick with 5 services on the central server, or would I need to define 5 different services for each remote server, so 60 total? And would that be 60 different routes defined on the central server? Based on my limited knowledge of routes and how they're tied to services, I think that would mean 60 routes, but maybe I'm missing something.
Please let me know. Thanks.

Hello, I have a datagridview setup right now to display data from one table in my database. However, I am going to need it to pull certain columns from certain tables and put them all into one datagrid. The three tables are demographics, financial, and procedures. Can someone give me an example on how I'd go about doing this? I'm using vb.net.
The procedures table is a list of options that will be displayed in a combo box, depending on the option selected, other cells in the datagrid will be filled with certain data, this data is in the procedures table as well. All of this data will be alongside a customer id located in the demographics table, and will all be recorded into the financial table.

Hey everyone,
I am trying to combine like data from two different data sources into a single data set. Is there anyway I can do this? It seems like I can only add one data set, but is there some sort of workaround I could use?

Hi,
I am new to Reporting Servies. I need to create a report that is shared by different offices, each office has it own database. So I will need to include multiple data sources. I want users to select their office first (parameter) and then based on their selection they can see the report with the data source from their office. Can I do it in one report. Or do I have to create multiple version of same report for each office. I would appreciate any help.

There are two EXCEL sources one destination table. Each record in the destination should be populated with 2 columns from one source and 2 from other source.
Source 1:
ID Name
1 abc
Source 2:
Address Location
232/2 xyz
Destination:
ID Name Address Location
1 abc 232/2 xyz
I tried using UNION ALL transformation but it fetches 2 seperate records (assuming that one record in each source). How to achieve this without using SCRIPT component?
TIA

ASP.NET on SQL ServerI've been asked to quote for developing a system to expose data on aweb application. Most of the data will come from SQL Server DBslocated on a single box. However, some of the data will be sourcedfrom ORACLE which is located on a different box. It may be necessaryto create VIEWS and Stored Procedures joining these DBsDoes anyone have any pointers, clues, hints, tips or pitfalls that Imight consider while making my proposal? What sort of extracontingency should I allow for the connection to ORACLE? Should I doall the data retrieval on the DB server, or should I do it on the Webserver?Any thoughts would be appreciated.ThanksWilliam Balmer

Hi,
Am having difficulty with report/query parameters, where the report now regularly tells me that I must declare the scalar variable @Site.
I want to use 3 data sources :
1. to select a site from a list of sites - works fine and I can select at runtime
2. Once this is selected - I need to present a pair of dates to the user - min and max for data for the site - needs selection 1 to have been performed. Now I HAVE seen this work - once, the date selectors were greyed out until the site had been chosen, then they became available. Now I get the scalar variable error.
3. Finally I will pull the data with 3 parameters (site, startdate, enddate)
This was almost working, and the detail was produced for item 3, until I introduced the date selection option. Now neither item 2 or 3 will accept the users selected site - its from a drop-down.
All 3 queries are being performed by SQL SP's :
1. exec getsitelist - used to populate the dropdown to select @Site
2. exec getdates @Site - used to preset the start/end dates (NB I would really like calendar control here to select the date, with the value pulled from 1 to set the start point - but hey lets walk first ;-).
3. exec GetData @Site, @Start, @End
SOooo - can SSRS2005 even support dependent parameters of this type ??.
If so - whats the best way to create the parameters etc. ??. NB I can see all 3 parameter defs in 'Report Parameters'.
Many thanks - hopefully - for my sanity :-O.
Regards
Graham

I am using SQL RS 2005. I have a report that is using multiple data sources from different offices. I can add these data sources in my report but is it possible that I can select a specific data source based on a selected parameter value. In this case user from each office, select their office location and be able to see the data from their office. I would appreciate any suggestions.

I have multiple data sources that I would like to use for a single report. The data sources are separate due to security requirements. I have a table that I can get the Initial Catalog from. How do I get that field from the database into the data source connection string at run time?
I saw this link here but the light bulb didn't go off:

"define a query that retrieves a list of data sources at run time"
Can somebody help me out here?

I have 5 or more tables to join to get a particular output which has to be sent to a destination table. In the 5 tables some are inner joins and some are left outer join. I am opting for stored procedure at this point. But I would like to know how can this be done in data flow transformations having multiple souce and merge joins or any other alternates. I tried using merge join, but this does not accept more than two tables.
I saw this simple post which kick started me to use ssis transformations to stored procedures. But I encounter issue.

error
"The destination component does not have any available inputs for use in creating a path".
Please advice alternates

Hi,
I have the following scenario: N identical Databases (corresponding to different Fiscal Years, with names <Company Name>.<YEAR>). We want to consolidate the N DBs to a New Datawarehouse.
In SSIS we have designed a Dataflow that reads through a OLE DB Source (Connected to one of the N Databases) and maps to a OLE DB Destination (Connected to the NEW DB).
The question is, how we loop in SSIS through the N identical Connections, so to repeatedly execute the designed Dataflow, each time with a different Connection?
Thanks in Advance,

Hi:
I have a data flow task in which there is a OLEDB source, derived column item, and a oledb destination. My source is a SQL command, that returns some values. I have some values, that I define in the derived columns, and set default values under the expression column. My question is, I also have some destination columns which in my OLEDB destination need another SQL command. How would I do that? Can I attach two or more OLEDB sources to one destination? How would I accomplish that? Thanks

I have a report designed in RB3 that uses a data source from a SQL database that is on the report server. I want to add data to the report from an access database an a network drive.
I can add the second data source and create a data set to add data to the report. The dataset query returns data from the Access database but when I run the report I get the following error.
An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'Feasibility'. (rsError OpeningConnection)
Also when I test the connection to the Access data base I get error ERROR (IM002) (Microsoft)(ODBC Driver Manger) Data source name not found and no default driver specified.
I noticed that Report Builder is connecting to the report server. If I disconnect from the report server I can a can connect to the Access data base but not the SQL database.
How can I get the report to run against both data sources?

Hi,
I am pretty new to SSIS. I am trying to create a package which can accept data in any of several formats. i.e. CSV, Excel, a SQL Server database/table and import the data into my destination database.
So far i've managed to get this working OK. However I am now TOTALLY stuck. I'm currently trying to just concentrate on the data sources being a CSV (using a Flat File Data Source) and/or an Excel Spreadsheet.
I can get the data in and to my destination using a UNION ALL component and mapping the data sources to it so long as both the CSV file and the Excel spreadsheet exist.
My problem is that I need my package to handle the possibility that only the CSV file might exist and there is no Excel spreadsheet. In which case i'd like the package to ignore the Excel datasource completely. Currently either of my data sources do not exist I get errors and the package terminates.
Is there any way in SSIS that I can check all my data sources to see which ones exist (i.e. are valid). If they exist I want to use them. If it doesn't exist i'd like to disgard it (without error - as long as there is a single datasource the package should run)
I've tried using the AcquireConnection method in a script task on each of my connections, hoping that it would error if the file/datasource did not exist. It doesn't though (in the case of an Excel datasource it just creates a empty excel file for me).
The only other option I can come up with are to have seperate packages depending on the type of data we want to import and then run a particular package depending on the format of the source data. This seems a bit long winded. I am pretty sure I must be able to do what I want to achieve but I can't work out how.
I'll be grateful to anyone who can send me any tips/hints/links on how I can achieve this.
Many thanks
Rob Gibson

Hello,
I have made a package to import data from a flat file datasource to our development SQL Server database and am very pleased about how well it works.
Now, it's time to import these data into our pre-production database using the same package. I am still wondering how to parametrize the connection string so that I can switch configuration easily. I specifically want to avoid creating 2 similar packages to do the same job but with different destinations.
I have read about variables and configurations but I am still confused. They say that the package has to be reloaded or something for a change to happen. At best, it would be perfect to have a drop down list somewhere, select the correct database and hit a button to execute the package. I would be very interested in knowing if .NET could be of any use for this kind of job.
Where can I get information about this topic?
Thanks!

During my development of a ssis package i've noticed that when creating two control flows that pulling data from seperate tables, each going to its own flat file, that the second keeps the attributes of the column names from the first. So when I create my second flat file, not only does it have the names of its correct columns but has the name of the the first flat file.
I'm hoping that I've explained the correctly. I'll provide more info "OR" I can provide the code to package if anyone would like.
