In this code I have a lot of errors, that they are about server and database don€™t have in current code,
In this code, first I should definition server or no?

Database dbNew = new Database (databaseName,
Utils.GetSyntacticallyValidID(databaseName, typeof(Database)));
srv.Databases.Add(dbNew);
dbNew.Update(true);
***********************************************************

How can I create data source and data source view and model and structure?
Please say code of that, and guide me.
databasename and srv is unknown.
Do I add other reference with analysis services?
Please explain about these codes:
************************************************************************
1)
RelationalDataSource dsNew = new RelationalDataSource(
datasourceName,
Utils.GetSyntacticallyValidID(
datasourceName,
typeof(RelationalDataSource)));

db.DataSources.Add(dsNew);
dsNew.ConnectionString = connectionString;

dsNew.Update();
2)

RelationalDataSourceView rdsv;

rdsv = db.DataSourceViews.Add(
datasourceviewName,

Add columns:
ScalarMiningStructureColumn smsc;

// From table "Customer" we will add a couple of columns
// CustomerID - key
smsc = new ScalarMiningStructureColumn("Customer ID",

mm.Columns.Add(mc);


mm.Update();

Please exactly say, whatever I want
Thanks a lot for your answer

Analysis :: Possible To Create Multiple Data Source View Having Same Datasource?

Jul 27, 2015

1. As per my current development SQL Sever Analysis Database consists of two Cube (Cube A and Cube B).  Cube A and Cube B share the same data source view (DSV1). The source for both these cubes has the same data source (DS1).

2. As per the requirement I need to create third Cube i.e. Cube C. Is it possible to create a second Data Source View (DSV2). The Source of second Data Source View (DSV2) will be the same data source(DS1).

I am thinking to create second Data Source View (DSV2) for Cube C because existing layout of the DSV1 has become complex. I wanted to know the pros and cons of creating a multiple data source view with same data source

Create Date Source View And Data Model That Works Right

Jan 22, 2008

I created a data model for report builder. And since it wont let me use views, i tried to put all the tables im using in one of my already made views, to create a data source view like my sql view. But when i connect everything the same, my report model still doesnt narrow my search. I only want to see Breed information, but since i have a Breeder table,and Customer table, its showing me all customers, and not limiting it to the ones that are breeder customers.

heres the tables:




Code Snippet

FROM dbo.Tbl_Customer INNER JOIN
dbo.Tbl_Customer_Breeder ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Breeder.Customer_Code INNER JOIN
dbo.Tbl_Customer_Detail ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Detail.Customer_Code INNER JOIN
dbo.Tbl_Customer_Category ON dbo.Tbl_Customer.Customer_Category_Id = dbo.Tbl_Customer_Category.Customer_Category_Id INNER JOIN
dbo.Tbl_Customer_Classification ON
dbo.Tbl_Customer.Customer_Classification_Id = dbo.Tbl_Customer_Classification.Customer_Classification_Id INNER JOIN
dbo.Tbl_Customer_In_Breed ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_In_Breed.Customer_Code INNER JOIN
dbo.Tbl_Breed ON dbo.Tbl_Customer_In_Breed.Breed_Id = dbo.Tbl_Breed.Breed_Id




What am i doing wrong, and are there any suggestions.

Loading Data Using Ole Db Source With Input Source Being A View

Dec 13, 2007

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.

The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.

Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

Cannot Create A Connection To Data Source 'data Source Name'

Dec 11, 2007

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).

We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.

When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?

Can someone tell me what is wrong?

How Do I Add An ODBC Connection Data Source As A Data Flow Source

Mar 2, 2007

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.

Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?

Thanks in advance

Report Models Data Source View

Apr 30, 2007

How does the report model know what data source view to use? I could not find it defined anywhere in the .smdl file.



My problem is this. I have a Report Model project with two data sources, two data source views and multiple report models. When I try and bind a data source to an entity in the report model I do not get to choose which data source view to use to choose what table/view I want to bind the entity too and only the tables in one of my DSV's shows up. When I first created it, it worked fine. It automatically selected the correct view and table and was successfully created but now when I open the project, that correlation is lost.



Any suggestions or help is appreciated, thanks.

Data Source View Missing Fields

May 9, 2008

Is there a limit on the number of fields that can be displayed in a table object in a data source view in SSAS 05?
One of the tables (the fact table) in my data source view is displaying only 50 fields. The table actually has many more than that. One of the fields that is not displaying is a foreign key that I need to link to a new dimension table. I have tried refreshing the view, but it doesn't bring in any additional fields.

Dynamic PIVOT Table As Data Source View

May 29, 2008

I would like to use a dynamic pivot table in my data source view. It seems that a named query can be only one sql statement. So, I cannot use my multi-statement procedure that creates a dynamic pivot table output.

What is the best course of action here? I could hard-code my pivot table query. I could maintain a redundant table in the pivot format. Do I have any good options?

The issue that we are having is Data Source Views can only see tables and views. Is it possible to use synonyms? If not what would be a work around.

I cannot get this error resolve either for myself or any users, and I'm actually part of the Admin group!  Furthermore, a user with whom I'm tring allow to view this report keeps getting prompted for their windows username and password.  I thought that since this datasource was set to Windows Authentification that it would just pass it through?

I'm pulling my hair out at this point:

Cannot Create A Connection To Data Source !!!

Mar 30, 2007

Hello everyone,



I posted the same issue before, but I couldn't find the solution yet. I am posting this agian cos I tried almost everything and I am not able to solve the issue.



Let me explain what is happening here:



Server A - is my development local machine

Server B - is the remote reporting server, where all reports are deployed

Server C - is where the databases are located



- After successfully deploying the project (the reports and datasources) on the remote server and try to run the report , I am getting the following error message



An error has occurred during report processing. (rsProcessingAborted)

Cannot create a connection to data source 'dsCallB'. (rsErrorOpeningConnection)

For more information about this error navigate to the report server on the local server machine, or enable remote errors

- I tried to deploy and run the same report on my local machine report server(Server A), which is still accessing the same database from Server C. This works fine.



So from this we can understand that A ==> B ==> C is not working, however A ==>C works fine(using Server A as a report server).



I almost tried all the possible solutions that are posted on the forum, such as storing the credential information on the report server (server B), created a data source, which is not a shared data source, on the report server level e.t.c. and I ended up with nuthin.



The weired thing is that there are existing reports that are already created and deployed(by somebody else) in the report server (server B) , which access the database on Server C. These existing reports run with no problem, even I can create a report which uses the existing data source and runs perfectly. However, when I create a new report which uses a different data source (from Server C), and deploy it to Server B and tried to run it, the above error message comes.



Please let me know if you have any idea.



Thx.

Create A Global Data Source

Aug 9, 2007



Hi guys,

I have a number of reports deployed on the report server. I want to point all these reports to another data source. Currently, what I am doing is go to the individual report on the report server and change the data source property to point to the new data source. It is very tedious to do the same thing for all of the reports.

So, Is there any way to point all the reports under a project at one time.

Any idea is appreciated.

Using Data Source View In Import Export Package Within Same Solution Is Not Possible ?

Dec 15, 2005

hello ,

 

I want to download data from an AS/400 to a SQL 2005 Database.

Within Sql server 2000 it was possible to do more than 1 transformation with just 1 source connenction and 1 destination.

In SSIS I have created:

-  new solution

-  data source

-  Data source viewer ( I made named queries to format the data as i want it to be in Sql)

Although it is possible to view the named query data it does not seem to be possible to import the data in the data viewer into my sql 2005 database. (For each dataflow I have to define each query again)

I have added the data source in the connection manager. 

Also I am searching to import more than 1 file in 1 package !

I can use however a Dts-2000 package but why then use SQL server 2005

Hope somebody can help me

Regard,

Ronny

Create ODBC Data Source To SQL Server DB

Jun 3, 2002

We have more than 10 databases on the same server. When I try to set up ODBC connection through my desktop to a specific database (DB1) using SQL authentication, it acts weird:

-- I give the login (testkz) access to DB1, DB1 does not show up in the default database list; I tried to type in the database name, it is not taken

-- If I give 'testkz' access to two other databases (and only these two), even though I did not give access to DB1, DB1 together with some other databases show up on the default database list. Seems to me that there are some dependency among the dbs.

Does anybody have any issues like this?

Your input is appreciated.

Cannot Create A Connection To The Data Source Error

Apr 22, 2008



Hi,

I have setup SSRS with 3 data models using 3 different datasources on one server. I can create reports ok, but if any of the other users I want to access these reports tries to open the report I created or run there own reports (they can create a report), it gives them the error:

Report Execution Error

Cannot create a connection to the data source 'datasource1'

I do not recieve this error, but the other users do. I have set the other users as System administrator in the site-wide permissions, so they have access to everything.

Everything is set to integrated windows authentication.

On the Reporting Server Configuration Manager, the Unattended Execution Account is not selected and is blank.

What could cause these users not to be able to run existing or new reports they create?

Thanks for any help,

Steve
