Power View with dynamic connection string, but server-side

We'd like to evaluate using Power View to provide exploratory BI over data output from HDInsight, onto Azure Storage. We need to let users select which segments of data to load but through a web-ui (not Excel on the desktop). We expect to have a standard
data model, it's just the segments of data that will be dynamically selected by the user. Basically the Power Query will need to be updated dynamically, but on the server-side. Is this scenario currently possible?

Any suggestions for SFiorito?
Thanks!

Report model dynamic connection string

hi
I'm trying to build a report model,which has to connect to different database
For ex:
I've 10 different customers, and i need to connect the selected customer database,
Any thoughts how to proceed in this
Thanks
Chezhian

Hi Chezhian,
As per my understanding, I would try the two methods to achieve your requirement: create one report model which contains those databases or create 10 report model, the data source can connect to the corresponding model based on the user. In Reporting Services,
a report model can only map to a database. So the first method doesn’t work. If we want to connect to a report model, we should browse to a report server or SharePoint site and select a published model. We don’t need a connection string to use a report model
as a data source. So the second method still doesn’t work.
To work around the issue, I think we can create 10 report model, each report model corresponding each user’s database and named the user name. Then set Item-Level Permissions of each report model based on the user on report manager. Each user can only see
his own report model on the report server.
Or we can create a data source with dynamic connection string, the blog below is for your reference:

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.

Running a SQL Stored Procedure from Power Query with Dynamic Parameters

Hi,
I want to execute a stored procedure from Power Query with dynamic parameters.
In normal process, query will look like below in Power Query. Here the value 'Dileep' is passed as a parameter value to SP.
    Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData 'Dileep'"]
Now I want to pass the value dynamically taking from excel sheet. I can get the required excel cell value in a variable but unable to pass it to query.
    Name_Parameter = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
    Name_Value = Name_Parameter{0}[Value],
I have tried like below but it is not working.
Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData Name_Value"]
Can anyone please help me with this issue.
Thanks
Dileep

Hi,
I got it. Below is the correct syntax.
Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData '" & Name_Value & "'"]
Thanks

Check string length server-side

Hi guys,
how do i check the string length server-side?
I am using the date object to gather the current date.
quote:
var d = new Date();
var mm = d.getMonth()+1;
var yy = d.getFullYear();
var dd = d.getDate();
month is returned as "2" which is correct
but i need to be able to check for a single char so that i
can add a leading zero before it is submitted to the database. This
is also required for day.
thanks

Sharepoint list dataheet view error "Cannot connect to the server at this time. You can continue working with this list, but some data may not be available"

I have a List which is having around 14000 items in it.while opening that list in datasheet view it is giving error .
Below is a summary of the issue:
After selecting datasheet view beow error occurs:
    "Cannot connect to the server at this time. You can continue working with this list, but some data may not be available."
    "Unable to retrieve all data."
    The item counts displays say 100 out of 14000 items.
Exporting List to excel is giving only 2000 records out of 14000 records.
Other Observations   -
This is happening to only one list on the site .There are other lists in the site whose no. of records is equal to 8000 to 9000.They are working absolutely fine without any error.
Also, If I am saving this list as a template and creating another list with it ,then it is working absolutely fine with 14000 records,so the issue does not seem to be related with no. of records as the template list is working fine.
I have checked the Alternate access mapping setting ,its fine.
It should not be related to lookup,datefield or any other column as the list created from it template is working fine with all these columns.
I checked below links also ,but doesn't seem to work in my case.

I have spent two days to resolve this issue. Microsoft has released two KBs with reference to this issue...but are not appearing in search results at the top.
I am sharing my finding.
1. First install the
KB2552989 (Hopefully you might have already installed it. The KB detetcts it and informs the user.)
2. Then update registry by adding new key for data fetch timeout as mentioned inKB2553007
These two steps resolved the issue in our environment. Hope it might help others as well.

How to specifiy the provider to be Oracle.ManagedDataAccess.Client when creating a dynamic connection string with EF Code First from Database?

I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC). First of all, it works fine as long as the connection string is inside the App.Config file. But when I try to build it dynamically in the C# code (or rather, statically at the moment) it fails. I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works.

SSRS 2012 - Windows Server 2012 R2 issue with OLEDB Connection String

Hoping someone can help. As stated above, we are running SQL Server 2012 with SP1 on Windows Server 2012 R2. When I create a Data Source as follows in Reporting Services, I receive the following error message. Any thoughts on why this fails? The same data
source works on Windows Server 2008 R2 Enterprise SQL Server 2008 R2.

Hi ABAA101,
According to your description, when you use csv file as data source in SSRS 2012 report, you got the error message.
I tested the issue in my local machine, due to some policy restrictions, I could not install Access in my local machine. To workaround the issue, we can use the connection string like below:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\report;
Extended Properties="text;HDR=Yes;FMT=Delimited"
The csv file is stored in report folder in C driver.
In Query text box in the dataset, we can use the query like below:
Select * from new.csv
If you have any more questions, please feel free to ask.

How to create dynamic Connection String in SSIS Package???

Hi
I created OLEDB Source Connnection String for that Package,
i need Create OLEDB Destination Connection String Dynamically,
Same server name,but i need to add DW at the end of the Database
ex:
Source database name is Demo,
Destination database should come DemoDW.
i need to create Dynamic Destination Connection String..
any possible to Create
Thanks in advance
Pandiyan
pandiyan

Hi Pandiyanpvp,
According to your description, the OLEDB Destination Connection String should be dynamically based on the OLEDB Source Connection String. They are all the same, except adding “DW” at the end of the Database of OLEDB Source Connection String in OLEDB Destination
Connection.
To achieve this requirement, we can create a variable with the Database name of OLEDB Source Connection String, then use expression to control the OLEDB Source and OLEDB Destination Connection Strings. For more details, please refer to the following steps:
Create a variable named Source with the Database name of OLEDB Source Connection String as value.
Click the OLEDB Source Connection Manager to navigate to the Properties window.
Click “…” next to Expressions to add a ConnectionString Property with the expression like below:
"Data Source=.;Initial Catalog="+@[User::Source] + ";Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
Click the OLEDB Destination Connection Manager to navigate to the Properties window.
Click “…” next to Expressions to add a ConnectionString Property with the expression like below:
"Data Source=.;Initial Catalog="+ @[User::Source] + "DB"+";Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
If there are any other questions, please feel free to ask.

Help with mySQL Connection string

Here is hoping someone can help & once I get it down I promise I'll post all my work on this list so some other newbie can benefit.
I'm simply trying to run a very very straightforward JDBC test with mySQL & I keep getting the "Server configuration denies access to data source" error. But before you tell me that I must simply look at what my mysql.db & mysql.user table allows - I'VE TRIED THAT. I realize that the error is probably there somewhere - but I can't see it.
I've tried connecting with 2 different accounts - the provided "root" & a user I created "deep" to 2 different databases the provided "test" & "testdb" which I created) . Here is what mysql says about the two different databases
mysql> select * from db;
Host | Db         | User |.......
-----+------------+-------
| %         | test    |       | ......
| %         | test\_% |     | ........
| localhost | testdb | deep |........Note that "root" should have access to "test" & deep@localhost should have access to "testdb" right?
So here are all the connection strings I have tried - all return the same error below
        Connection conn = DriverManager.getConnection(
            "jdbc:mysql://localhost:3306/test", "root", "mypass"
//            "jdbc:mysql://localhost:3306/testdb", "deep", "mypass"
//            "jdbc:mysql://localhost/testdb?user=deep&password=mypass"
//            "jdbc:mysql://localhost/testdb", "deep", "mypass"
//            "jdbc:mysql://localhost:3306/testdb?user=deep@localhost&password=mypass"
//            "jdbc:mysql://localhost:3306/testdb?user=deep&password=mypass"

Dynamic connection string not working in SSIS package 2008R2

I am using SSIS package for Import data from excel sheet to SQL DB. In the configuration file I'm using following variables.
Name scope DataType Value
DBName package String DB_Master
Password package String xx
UserName package String sa
ServerName package String xxx.xxx.x.xx
SqlConnectionString package String DataSource=xxx.xxx.x.xxx;UserID=sa;Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;Initial Catalog=DB_Master;Password=xx
Right click OLEDB ConnectionManager then click properties window below values assign
ConnectionString - Initial Catalog=DB_Master;DataSource=xxx.xxx.x.xxx;UserID=sa;Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;
DelayValidation - True
Expressions -ConnectionString - @[User::SqlConnectionString]
In SqlConnectionString variable properties window below values assign

After deploy the package file I change the DBName in SqlConnectionString DB_Master to Master but package execute the files in DB_Master.
and also if i give invalid ServerName like 198.152.1 but package executed successfully.
Please tell me where i made mistake. what's goes wrong...?
I just use variable like below link
https://anothersqlgeek.wordpress.com/2013/03/28/ssis-dynamic-connections-part-1/comment-page-1/#comment-48

First see whether you've some other configurations also set inside the package for the same properties? ie direct configuration for connection manager properties.
Secondly see if its executed from a job and you're overriding the values through the job properties.

Can't See Fields or Views with Oracle Connection

We have a report that connected to Oracle. Previously, we were able to see the tables and views and connected some of them in our report. However, now we can't see those tables or views. We can see the fields under them but not the tables or views they belong to. Is there anything we can change to fix this?

Hi,
please check in Options --> Database Tab --> Tables,Views,Stored procedures are checked .
If you are using Odbc connection some times it may happen. Try with oledb connection

Connection String SQL SERVER 2000

Hi everybody:
I have a problem:
I want to connect to Sql Server 2000 from Java Server Pages but I can not do it.
In Active Server Pages I connect using:
"Provider=SQLOLEDB;Data Source=" SERVIDOR";Initial Catalog=IntranetHipohard;User id=sa;Password="
I would like that somebody write me by email.
This string not is valid for Java Server Pages.
How can I do it?
Thank you very much and sorry my language.

Well, it entirely depends on the JDBC driver you are using. If you are using Microsoft's driver currently in beta 2 (http://www.microsoft.com/sql), you use the following:
Driver Name
com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection URL
jdbc:microsoft:sqlserver://<HOST>:1433;DatabaseName=<DATABASE>;User=<USER>;Password=<PASSWORD>
Where <HOST> is the IP or hostname of the machine running SQL Server 2000, and <DATABASE> is the name of the database you are connecting to (optional).
Hope this is what you need.
