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.

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.

Report Designer odbc connection string for data source using a parameter

I am using stand alone report designer 3 for the present and have a question/problem regarding the odbc connection string for MySQL when setting up the data-source
I need to be able to enter a parameter which is the database name i.e. BOE-201401 or say BOE-201312 etc from a list of databases the user can choose from.
at present the odbc connection string points to BOE-201402
the connection string is at present Dsn=Development Server for MYsql;description=MYSQL;server=ldndw01;database=BOE-201402;port=3306
my parameter has the name BOE_DATABASE
and in an expression it is as such
=Parameters!BOE_DATABASE.Value
I want to point the datasource for the report to the parameter value before the user sees the report.

Hi Leslie,
Based on your description, we want to design a report with a dynamic DataSource connection string. There are the basic steps below for your reference:
Create report with static database.
Change data source to report parameter.
Send new database connection string as a report parameter.
More detail information, please refer to the following blog: Dynamic Database in SSRS 2008.

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
EvaluateAsExpression -True
Expression -"DataSource=" + @[User::ServerName] + ";UserID=" + @[User::UserName] + ";Provider=SQLNCLI10.1;Integrated Security=SSPI;Auto Translate=False;Initial Catalog=" + @[User::DBName] + ";Password=" + @[User::Password]
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.

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.

XI R2 report with dynamic connection

I am looking for a simple sample *.aspx application (.NET 2.0 prefered) that will take a report name and connection name (as in the repository) and run the report for the current user (All my users are in the AD and single sign on works)
There is so much here, it is hard to find the simple stuff

Please re-post if this is still an issue to the .NET Development - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly

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!

JDBC Adapter Receiver dynamic connection string

Hi,
I'm developing an IDOC-JDBC scenario and I need to send data to one of the different databases depending of one field in the IDOC. All databases are identical, the only difference is the server where they are. We are using SAP PI 7.0. If you need more information, please report.
Best Regards,
Alfredo Lagunar.

Hi Alfredo,
no bother to think about dynamic varialble substitution or something like that, which might be possible, might be not. In this case, you just configure several receiver channels and serveral receiver business services. By using the conditioning(XPATH) winthin receiver determination you can route your XML message to the JDBC database with different IP addresses.
Actually SAP is using the same solution in one of its standard implementation: ELSTER (Electronic Tax Claim, in german Elektronische Steuererklärung). The only difference is the receivers are HTTP endpoint, not JDBC. But the idea is the identical: they are all having different IPs, like your databases.
Hope it inspires.

Chen

Database connection string dynamic

Hello everybody,
My application should do some tests that user choses.
For each test type I should save the database in a file with different name, something like : Report_YYYY_MM_DD_Test_x, without stopping the execution of the application.
My problem is that i cannont rename the database after Teststand wrote in it. I must stop first the application and then I can rename it.
I tried to build dynamic connection strings and to prepare the database before Teststand write it. But I saw that after the first acces, despite of new connection string, Testand write further in the database described in the first connection string. Also seems that the handle to database once established, will be released at the end of test. I could close the connection to the DB but i don't know if it is possible.
for any ideea how to handle this situation i would be grateful

Hi Harleen Kaur Chadha,
I understand your requirement is access 5-6 database on same server using one JDB receiver channel. I think, it is possible. SAP Help [Link|http://help.sap.com/saphelp_nwpi711/helpdata/en/44/7c24a75cf83672e10000000a114a6b/frameset.htm ]. In receiver JDB channel select Message Protocol : u201CNative SQL Stringu201D. Then you have make sure that the payload coming to this JDBC receiver channel should look like this
INSERT INTO DatabaseName : tableName
(column-name1, column-name2, column-name3)
VALUES(u2018column-value1u2019, u2018column-value2u2019, u2018column-value3u2019)
But, the mapping program you are using now, should generate the String (shown above). And SAP says this protocol is primarily for test purposes.
FYI. If you select Message Protocol: "XML SQL Format", finally it would be converted to string (shown above) will be sent to database.

C How to Set Isolation Level in the Connection String

How to Set Isolation Level in the Connection String using the "Microsoft OLE DB Provider for DB2 Version 4.0"?
We are trying to move from Crystal Reporting that run against a IBM DB2 database on a mainfram to SSRS reporting and we have downloaded the "Microsoft OLE DB Provider for DB2 Version 4.0" and then worked with the DB2 Administrator to create the
Packages. We only have access to use the "Read Uncommitted ("MSUR001") package. We were able to connect and pull data before he removed access to the other packages, but after setting access the Connection keeps trying to use
the 'Cursor Stability (MSCS001)" package. How do we change the Default to the "Read Uncommitted ("MSUR001") package??? Since it is keeps defaulting to the the other package
we can't connect to do it in the T-SQL query, it has to be set at the Connection String level.

Hi Dannyboy1263,
According to your description, you want to set the Transaction Isolation Level in Connection String. Right?
In Reporting Services, the Connection String for OLE DB Connection can only contains Provider, Data Source and Initial Catalog. There's no property for setting Transaction Isolation Level in the Connection String. Based on my knowledge, we can
only set the Transaction Isolation Level at Query level or set it by using code (C#, VB, Java...) to call the property of Connection. So unfortunately your requirement can't be achieved currently.

How to dynamically set connection string for report in C# code?

Hi,
I have installed CRVS2010. I have created new Crystal Report WPF Application and new report. I would like to set connection string for report in code dynamically.
Is this possible?
Thanks
Ivana

Lots of posts in this forum on how to set database connections. WPF should not be a consideration as it's just a viewer. The report engine is still the same. Search these forums. Use the search box at the top right corner of this page. Look at samples here:
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
Note that none of the samples above are using WPF, but like I said, the WPF is just a different viewer and will not impact how the report engine logs on to a database. (I think of it as a gray car vs. a red car. Same engine, just the color is different)
