Dynamic connection string
Hello all
This is Charitha Sharma
i want to know how to and where to store connection string in my applications
we are using multi user environment model system ( network model ) 10 clients connects to server
tech is VB2005 AND ORACLE
i dont want to embedd username and password and host name in connection string
please guide me in real time application developement which one is better one
DSN OR WRITING IT IN ANY FILE OR ......
IF DSN HOW TO ACCESS ITS VALUES IN VB?
OR
WHICH WAY I CAN COMPLETE THIS TASK
THANK YOU
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 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.

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
ChezhianHi 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:

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.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).

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

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
pandiyanHi 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.
Thanks,

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?

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.

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 gratefulHi 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.

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
IvanaLots 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)

Dynamically Setting a Variable from a Connection String that has been set by a Config File
Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

ISQL*PLUS dynamic reports - how to pass connect string in the URL
When we run dynamic reports thru ISQL*PLUS, does anyone know how
to pass the connect string info in the URL
The following is the code from ISQL*PLUS users guide but it
dosen't show how to pass the connect string
when I tried to pass hr/your_secret_password@dbserver for userid
I got an error msg
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<HTML>
<HEAD>
<TITLE>iSQL*Plus Dynamic Report</TITLE>

Thanks
JayThe form you use should work when your change
"hr/your_secret_password" to a valid username, password
and connect identifier like "hr/hr@MYDB". Don't forget to
configure MYDB in your tnsnames.ora file on the machine that has
the iSQL*Plus server.
What was the error you got?
The full URL syntax did seem to go missing from the 9.0.1 doc.
See below for the full syntax. This should be appearing in a
forthcoming FAQ.
- CJ
What syntax can I use to run an iSQL*Plus Dynamic Report?
You can run a dynamic report by entering the report URI in the
location field of your browser, or by making the report server a
link or the action for an HTML form. The iSQL*Plus 9i Release 1
documentation has examples of these.
The general syntax for running a dynamic report is:
{uri}?[userid=logon&]script=location[¶m...]
where uri
Represents the Uniform Resource Identifier (URI)
of the iSQL*Plus Server, for example:
http://host.domain/isqlplus
where logon
Represents the log in to the database to which you
want to connect:
{username[/password][@connect_identifier]}
where location
Represents the URI of the script you want to run.
The syntax is:
http://[host.domain/script_name]
The host serving the script does not have to be
the same as the machine running the iSQL*Plus server.
where param
Specifies the named parameters for the script you
want to run.
Named parameters consist of varname=value pairs.
iSQL*Plus will define the variable varname to equal value prior
to executing the script e.g.
...script=http://server/s1.sql&var1=hello&var2=world
This is equivalent to the SQL*Plus commands:
SQL> define var1=hello
SQL> define var2=world
SQL> @http://server/s1.sql
iSQL*Plus, SQL*Plus and SQL keywords are reserved
and must not be used as the variable names (varname). Note also,
that since variables are delimited by the ampersand character,
there is no requirement to enclose space delimited values with
quotes. However, to embed the ampersand character itself in the
value, it will be necessary to use quotes.
For compatibility with older scripts using the &1
variable syntax, varname may be replaced with the equivalent
variable position as in:
...script=http://server/s1.sql&1=hello&2=world
Note the & is the URL parameter separator and not
related to the script's substitution variable syntax.
Commands and script parameters may be given in any
order in the dynamic report URI. However, please note that if any
parameters begin with reserved keywords such as "script" or
"userid" then it may be interpreted as a command rather than a
literal parameter. -
Changing Connection String dynamically at runtime
I am using the Crystal Report Viewer control in in a Visuall Studio 2008 C# project. The reports are created inside of Visual Studio 2008, and will be running against an InterSystems Cache database. I have to use an ODBC (RDO) connection and use a connection string.
I have seen many examples of how to update the connection string at runtime if it is SQL server (or some flavor thereof), but nothing for an ODBC (RDO) connection to a NON-MSSQL database.
The problem when I update the connection string for each of the tables in the report, the report will either not run and display a window -- tiled 'Datbase Login' -- that has the Server, Database, Username, and Password fields on the window, OR, it will run but not against the database that was specified at runtime (it uses the connection stored in the report).
Code Sample #1 (This is using the connection string, and will cause a the "Database Login" window to be displayed - the first scenario from above)
rd = new ReportDocument();
// Load the report
rd.Load(fileName, OpenReportMethod.OpenReportByDefault);
rd.Refresh();
// Create the connection object
ConnectionInfo connectionInfo = CreateConnection(Server, Port, ServerNamespace, Username, Password);
// Set the connection info on each table in the report
SetDBLogonForReport(connectionInfo, rd);
SetDBLogonForSubreports(connectionInfo, rd);
private static ConnectionInfo CreateConnection(string Server,
int Port,
string ServerNamespace,
string Username,
string Password)
ConnectionInfo connectionInfo = new ConnectionInfo();
string connString = "DRIVER=InterSystems ODBC;SERVER=" + Server
+ ";PORT=" + Port
+ ";DATABASE=" + ServerNamespace
+ ";UID=" + Username
+ ";PWD=" + Password;
connectionInfo.IntegratedSecurity = false;
connectionInfo.UserID = Username;
connectionInfo.Password = Password; //In examples that I have seen, this is the actual connection string, not just the server name
connectionInfo.ServerName = connString; connectionInfo.DatabaseName = ServerNamespace;
connectionInfo.Type = ConnectionInfoType.CRQE;
return connectionInfo;
private static void SetDBLogonForReport(ConnectionInfo connectionInfo, ReportDocument reportDocument)
foreach (CrystalDecisions.CrystalReports.Engine.Table table in reportDocument.Database.Tables)
TableLogOnInfo tableLogonInfo = table.LogOnInfo;
tableLogonInfo.ConnectionInfo = connectionInfo;
table.ApplyLogOnInfo(tableLogonInfo);
private static void SetDBLogonForSubreports(ConnectionInfo connectionInfo, ReportDocument reportDocument)
foreach (Section section in reportDocument.ReportDefinition.Sections)
foreach (ReportObject reportObject in section.ReportObjects)
if (reportObject.Kind == ReportObjectKind.SubreportObject)
SubreportObject subreportObject = (SubreportObject)reportObject;
ReportDocument subReportDocument = subreportObject.OpenSubreport(subreportObject.SubreportName);
SetDBLogonForReport(connectionInfo, subReportDocument);
Sample #2 (the same as Sample #1 above, only the ConnectionInfo method is different - which is all that I included here)
private static ConnectionInfo CreateConnection(string Server,
int Port,
string ServerNamespace,
string Username,
string Password)
ConnectionInfo connectionInfo = new ConnectionInfo();
string connString = "DRIVER=InterSystems ODBC;SERVER=" + Server
+ ";PORT=" + Port
+ ";DATABASE=" + ServerNamespace
+ ";UID=" + Username
+ ";PWD=" + Password;
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
DbConnectionAttributes.CONNINFO_DATABASE_DLL, DbConnectionAttributes.DATABASE_DLL_CRDB_ODBC));
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
DbConnectionAttributes.QE_DATABASE_NAME, ServerNamespace));
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
"QE_DatabaseType", "ODBC (RDO)"));
DbConnectionAttributes attributes = new DbConnectionAttributes();
attributes.Collection.Add(new NameValuePair2(
DbConnectionAttributes.CONNINFO_CONNECTION_STRING, connString));
attributes.Collection.Add(new NameValuePair2(
"Server", Server));
attributes.Collection.Add(new NameValuePair2(
"UseDSNProperties", false));
connectionInfo.Attributes.Collection.Add(new NameValuePair2
( DbConnectionAttributes.QE_LOGON_PROPERTIES, attributes));
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
DbConnectionAttributes.QE_SERVER_DESCRIPTION, Server));
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
"QE_SQLDB", true));
connectionInfo.Attributes.Collection.Add(new NameValuePair2(
DbConnectionAttributes.CONNINFO_SSO_ENABLED, false));
connectionInfo.IntegratedSecurity = false;
connectionInfo.UserID = Username;
connectionInfo.Password = Password;
connectionInfo.ServerName = connString;
connectionInfo.DatabaseName = ServerNamespace;
connectionInfo.Type = ConnectionInfoType.CRQE;
return connectionInfo;
I have also tried setting connectionInfo.ServerName equal to just the real server name, but that didn't work either.
After the above operations are performed, I simply assign the returned ReportDocument object to the Crystal Viewer control. If I don't call the above functions, and just set the ReportDocument source (using whatever connection string was embedded in the report originally), the report runs as expected. Only when I attempt to update the connection string, the report will not execute. Please advise. Thanks!I am using the Crystal Report Viewer control in in a Visuall Studio 2008 C# project.
