I'm just wondering if it is bad programming practice to have many data sources on one page. I need a "Matrix" type of page that grabs data from many tables and so far I have 5 data sources. Is this common or is there something I should be doing to make it more efficient?
View 1 RepliesHi, i'm wondering which is the best way to search data in a SQL Server.
I reach data using Data Sources and Data Views and also with OLE DB Source with a Data access mode: Named query.
I have to write the data into a Flat File. So, does any one knows which is the best practice for this? Or any one of the two are good choices?
Thanks for your help.

I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios:
Some of the records in the external data source may not exist in SQL.Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server.Some of the records in the external data source may be the same in SQL.
Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 above). In fact case 2 is the most critical.
I thought of making a query with a left outer join between the data in the external data source table (SOURCE) and the data in the SQL Server table (DESTIN). The join is done on the respective primary keys (composed keys of up to 10 columns) and one of the WHERE conditions will be that the value in SOURCE is different from the value in DESTIN.
The result of this query would be exactly what I need to import.
How to do this in SSIS??? I couldn't figure out how to join tables in different data sources yet.
In fact I cannot write a stored procedure to do that, since one of the sources is in a datasources not SQL Server.
I have seen the Lookup transformation in this article http://www.sqlis.com/default.aspx?311 but this is not exacltly what I want to do.
Another possibility is to use the merge join, but due to the sorting I believe its performances would be terrible!
Thanks in advance for your suggestions!
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

Hi,
In my project i want a report. In that report data is getting from more than one data sources(systems). While creating data source view i used named query for both primary and secondary data source. But at the time of crating "Report Model" i am getting below error.
An error occurred while executing a command.
Message: Invalid object name 'Table2'.
Command:
SELECT COUNT(*) FROM (SELECT SerialNum, ModelNum AS com_model
FROM Table2) t
Is there any way to create a report with multiple data sources?
Hi all :)
I'm wondering if SSIS will be the solution to the problem I'm working on.
Some of our customers give us an Excel sheet with data they want to insert or update in the database.
I've created a package that will take an Excel sheet, do some data conversion so the data types match up and after that I use a Slowly Changing Data component to create the insert/update commands.
This works great. If a customer adds a new row to the Excel sheet or updates an existing row changes are nicely reflected in the database.
But now I€™ve got the following problem. The column names and the order of the columns in the Excel sheet are not standard and in the future it could happen a customer doesn't even use an Excel sheet but something totally different.
Can I use SSIS for this? Is it possible to let the user set the mappings trough some sort of user interface? I€™ve looked at programmatically creating the package but I€™ve got to say that€™s quit hard to do€¦ It would be easier to write the whole thing myself than to create the package trough code ;)
If not I thought about transforming the data in code before I pass it on to the SSIS package in something like XML. That way I can use standard column names and data types.
So how should I solve this problem? Use SSIS or not?
Thnx :)

Hi i have data on a Server in a different database which i like to access from within my ssis job.
I just need to look up information from one table on this database so i can references it. Is there a way of doing this is SSIS. Rather then me having to load the data from one database to another as the data may change.
i tried having 2 sources of data feed into a look up but that does not work..
Hi there,
On my home page I have several different folders to reports which require different data sources. the problem is that within these folders there are multiple copies of the same datasource. is it possible to store all of the datasources in one folder, one location? it would certainly be easier when changes to usernames and passwords need to be modified!
Thanks,
Rhonda
I searched and read about Data Sources and I'm seeing that there is no advantage in using it, which is what I found from playing around with it.
I expected that you would set a global connection in Data Sources and somehow link this to the things in your Connection Manager, giving you one place to switch from one environment to another. But reading the discussions here and playing around with it, this is not the case.
So, why is it there?
Next question.... another thing I gathered so far is something called "Configurations" that will do what I was describing above. Where do I do this?
Hi,
how can i use var for Data Sources ,
my project have to be suitable for the QA system and the production system and i want to connect them by var or something else.
if you have another idea about this subject i'll happy to read.
thanks,

I'm trying to combine two reports I've created into a form letter. The goal is to have a letter that indicates the students maximum UBSCT score for Math, Reading and Writing. Also in the letter we want to include the student's total number of credits awarded and overall GPA. I not sure if I need to try and combined the two queries or use two different data sources in Reporting Services. I've tried creating one sql statement but the grouping are giving me fits. I fairly new to Reporting Services.

Hi guys,
I manage to get the SSIS working. Now I would need to do these tasks.
I first want to get data from 2 different sql servers. What would be the best method to accomplish this? Both are in Sql Server 2005.
Secondly I want to make sure if any of the servers couldn't be found on the network or in any case the getting data task failed for any one of them the package won't continue and an email should be send to an email address.
Thirdly If everything is ok then I should combine both and generate one sequence no for them and save them on to another location and then generate a file with modified values.
Can anyone help me regarding these tasks?
Thank you
Gemma
In brief, here is my quandary… I have a GridView on a page with some radio buttons, a couple of check boxes, some drop downs etc. And depending on what the user selects the Grid View needs to show different columns from the database…
The easiest way I have found to do this is to have a separate Data Object for each “view�, i.e. each variation of the checkboxes and radio buttons (which determine which dropdowns to use for the variables) and then bind the GridView to the specific Data Source at runtime…
It seemed like a good idea at the time, but now I have over 7 different data connections cluttering up the design view, and more to come and I feel like I am missing a better way to achieve the same results…
Does anyone have some advice for a major novice?
Here’s the beginning of a large set of nested ifs, if this is the way it’s done that’s fine too, I’ll just keep creating data sources, I just get the feeling there must be an easier way to do this..
protected void Button1_Click1(object sender, EventArgs e)
{
if (RadioButtonList1.SelectedValue == "Vendor") {
if (CheckBox1.Checked == true) {
GridView2.DataSourceID = "ObjectDataSource4";
GridView2.DataBind();
TextBox1.Text = "Search";
} else {
GridView2.DataSourceID = "ObjectDataSource1";
GridView2.DataBind();
TextBox1.Text = "Search";
}
} else if (RadioButtonList1.SelectedValue == "Store Number")
{ GridView2.DataSourceID = "ObjectDataSource2";
GridView2.DataBind();}
else {
GridView2.DataSourceID = "ObjectDataSource3";
GridView2.DataBind();
TextBox1.Text = "Search";
}
}
Any advice for a major novice would be greatly appreciated! Thanks!
Is it possible to create a recordset from two different datasources?
Such as
SELECT * FROM DataSource1.TableName WHERE ColumnName IN (SELECT Column FROM Datasource2.TableName)

Can I import in my query a file from other sources (in this case it's a job that has elaborated server database data, but I could be in the need of using for instance Excel files or others) and compare its fields with the tables in my query?
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?
If I were to change a data source that many packages use (say, from box "SQL-2" to "SQL-1"), would I have to re-upload the packages that used that data source? Or would the packages already on the server receive that change somehow?
(currently realizing that most of the packages use package-local data connections instead of project-wide data sources...)
Thanks!

Hey all,
I'm coming from ASP and I used to have a global connection string accessible to all of my ASP pages that I'd use for all of my data access. This was really convenient because I could easily switch to a backup or local data source for testing/debug by changing the connection string in one place.
Now, I'm using ASP.NET with Web Matrix and I love the drag and drop functionality but its dropping my connection string all over the place. How can I do this and keep my connection string in one spot so I can have the same convenience of switching data sources.
Thanks in advance!

I am using SQL Server 2012, and I have a query that gets data from 4 different sources and sums them all up into one field to get a total, and right now I am using 4 queries for each data source and using UNION ALLs to combine them and I was wondering if there is a different way to accomplish this without using UNION statements.Here is a sample of my code.
SELECT
Resv01 = ISNULL(SUM(Resv01),0)
FROM
(
SELECT
Resv01 = SUM(Reservations)

For credentials, I have a Shared Data Source that "uses a specific user name and password".
When I open the data source's RDS file, I observed that the credentials are not stored in the RDS file.
Where are the credentials for the data sources stored?
It has to be stored somewhere. When I close and reopen the solution, the credentials for the data source are still intact.
Hi,
I have to get all the customer records from one table and compare this records with another table and finally if there is same record I have to perform an update but the record does not exist I have to make an insert.
How can I do it with SSIS Except writing sql or tsql scripts ?
thanks,

I want to configure a Data Source and then Deploy the Data Source and Data Source view along with several packages that use connection managers based on the Data Source/Data Source Views.
Can someone explain this process?
Thanks,

Is it possible to tie a linked report to a different data source that the base report?
I have a set of base reports that point to Data Source A.
I have a set of linked reports that I want to point to Data Source B. These linked reports live in a different folder altogether.
Is there a simple way to accomplish this?
Thanks In Advance...
I notice that when deploying a package that uses data sources behind its connection managers, the deployed package has the connection string built within the package that gets deployed.

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.

Is there a way to do this? It does not appear as part of the standard SSIS API.
Thanks.
We're looking at using SSRS for all our new reporting requirements. However, we use SQLServer(2000 and 2005), Ingres and Postgres DBMSs. Ideally, we'd like to use SSRS against databases within all 3 DBMS. Ingres can be accessed via ODBC, JDBC, and has a .NET data provider, but no oledb data provider. Postgres can be accessed via ODBC. Reading some of the threads on this forum, there appears to be some limitations on the features of SSRS that can be used when accessing a database via ODBC compared to OLEDB. I'd like to understand these limitations if they exist so that we can work round them. Could anyone point me in the direction of a document that covers this issue, or outline what the issues are.
Many Thanks
Tony.
I could see the preview of my report without any problem. But when I deploy on a sever and select a parameter I m getting following error
€śOne or more data sources is missing credentials€?
My report contains single value parameters and a dependence parameter.
I think this error occur bcos of that dependence parameter.
If I change single value parameter as multivalve parameters it is working fine without any error.
And also if I make dependence parameter as my first parameter it is working fine
Is it a bug in sp2??????
Or
Can v solve this problem???
Greetings my SSIS friends
This is probably a silly question but what exactly is the purpose of creating Data Sources when it is possible to set up individual connection managers?
Thanks for your help in advance.
Hi report data sources keep losing their credentials. We use custom datasources and store credentials on the server yet for some reason? the credentials get removed and have to be re entered.
Has anyone come acroos this before?
Hi,
I have a datasource to an SQL server table which is used in a dataset with the following sql
e.g.
select *
from tblcustomer

how would i go about doing this?
I tried the below which failed, anyone can help?
select *
from tblcustomer LEFT JOIN server1.database1.tbluser on server1.database1.tbluser.userid = tblcustomer.userid
