Setup
In the local environments, we're using SQL Authentication with Username and Password to connect to the databases. I created a Project Connection Manager that has expressions bound to Project Properties, Username and Password being set to sensitive.
On the dev server, when the SSIS run, it needs to use an AD account. I might need to create a Credential/Proxy for the SQL Agent, but for now I'm logged in as the user and I execute the packag through SQL.
Problem
In the SSIS project itself, I'm trying to configure a dynamic connection string to use Integrated Security in one case, and SQL Account in another. I just can't figure out how to do it. Things I tried:
1- Created a boolean "UseIntegratedSecurity" parameter. In the connection string, use that bool to set IntegratedSecurity=SSPI or not with the expression, and also use expressions to set the other attributes of the connection string individually. It didn't work, said the connection string could not be built.
2- Created a boolean "UseIntegratedSecurity" parameter, and write my connection string as something (ugly) like: #[$Project::IntegratedSecurity] ? "Data Source="+#[$Project::SqlServerName]+";Initial Catalog="+#[$Project::SqlServerDatabase]+";Provider=SQLNCLI11.1;Auto Translate=False;Integrated Security=SSPI;" : "Data Source="+#[$Project::SqlServerName]+";Initial Catalog="+#[$Project::SqlServerDatabase]+";Provider=SQLNCLI11.1;Auto Translate=False;User ID="+#[$Project::SqlServerUsername]+";Password=" + #[$Project::SqlServerPassword]
It didn't work because since SqlServerUserName and SqlServerPassword are sensitive, it refuses.
3- Tried having Project Parameters for ConnectionString, Server, Database, User, Password and setting them all. Works locally, but on the server, I get "Invalid Authorization Specifications".
Ideas?
Thanks
You need to handle situation when in one environment you have to use SQL Authentication, and on the other - AD Authentication.
This can be done with help of SSIS Catalog Environment variables. When you create a Project file, Visual Studio automatically creates the following so called project connection parameters for each OLEDB connection manager :
CM.< conn manager name >.ConnectionString
CM.< conn manager name >.InitialCatalog
CM.< conn manager name >.Password Created as sensitive param
CM.< conn manager name >.ServerName
CM.< conn manager name >.UserName
OLEDB is an example, SSIS creates similar parameters for other connection manager types.
Important fact, you do not have to create additional project parameters. The parameters mentioned are created on project being built and are present on all projects.
We create environment variables which specify connection string, DB name (initial catalog), Server Name etc. Good thing - Connection string variable is applied first, and then amended with the other variables.
More details on these parameters is in MS Docs.
In case similar to yours, in Dev environment - using SQL Auth define Conn string for SQL Auth and specify username and password in corresponding variables. In QA env where SSPI is used - the Connection string is reworked for SSPI, UserName and Password environment variables are empty.

I'm working on an SSIS package to extract data from one old database and move to a SQL database. The only way to connect to the source database is using ODBC. I set up an ADO.NET connection manager and project parameters to store the username and password. Then I went to the connection and chose "Parameterize...". I selected username and password and linked to the project parameters I set up. The connection continues to fail. The only way I've been able to get it to work is to allow the package to save sensitive data and to save the password in the connection manager (going to edit, typing in username and password, then saving). If I rely on the parameters it does not work. I also tried deploying to the SSIS catalog, then executing by going to the package and entering the credentials under the Connections Managers tab. The only way I've been able to get this to work is to allow it to save sensitive data, enter credentials directly in the package and then save.
I cannot figure out why it will not pass the username and password from parameters or with the connection manager when executing in SSMS. The error I get back is that it's missing the password.
Any help would be greatly appreciated! I'm not new to SSIS, but have tried everything and can't seem to make this one work. I'm stuck using ADO.NET and ODBC.
Few things to do:
Set the SSIS package ProtectionLevel to SaveNoSensitive.
Go to the connection and chose "Parameterize..." and select the
entire connection string.
Assign proper values to Project level parameter that is used to parameterize the enire connection string.
In SSIS I am using Project.params to parameterize a database connection string. Using the windows authentication this is simple, however I would like to do this with SQL authentication instead. The connection will be used in an Execute SQL task to execute a stored proc that just gets a list of data. Generating the parameter with SQL auth. The password is not stored (this is fine), so I added four parameters: Server, DBName, DBUser, DBPass. I want to be able to dynamically change any of these at runtime. So my thought was to build the connection string on the connection string property of the db connection manager. Issue is that it doesn't seem to want to validate. Here is an idea of what I'm trying to do.
Expression:"Data Source="+ #[$Project::ServerName]+";Initial Catalog="+ #[$Project::DBName]+";User="+ #[$Project::DBUserName]+";password=" +#[$Project::DBPassword]+";"
Sensitive parameters (the password) cannot be used in expressions. You will see an error message like this:
Expression cannot be evaluated.
The expression will not be evaluated because it contains sensitive parameter
variable "$Package::pw". Verify that the expression is used properly
and that it protects the sensitive information.
You can do as Nick suggested and parameterize the connection manager directly. I would suggest only parameterizing the connectionstring and password (separately). This would allow you to alter between windows and sql authentication.
i.e.
Windows:
Connectionstring: Data Source=;Initial Catalog=;Provider=SQLNCLI11.1;Integrated Security=SSPI;
Password: leave blank
SQL:
ConnectionString: Data Source=;Initial Catalog=;Provider=SQLNCLI11.1;User Id=
Password:
I don't know much about databases - Sorry if the question seems silly.
I have sql server 2012 on my machine and i create simple database table.
I want to connect to this database table thru C# code.
So, I need to know my ConnectionString.
I don't understand the parameters of the ConnectionString.
I try to google it - but still didn't find any good explanation.
Anyone can please explain the connectionString fields ?
How to define the connectionString that i will be able to connect the local database ?
thanks
Your connection string should be as simple as like below
Data Source=.;Initial Catalog=DB_NAME;Integrated Security=True"
Where
Data Source=. means local database
Initial Catalog=DB_NAME means the database it will connect to
Integrated Security=True means it will use windows authentication (no user name and password needed; it will use logged in credential)
Take a look Here
(OR)
Search in Google with key term sqlconncectionstring which will fetch you many help.
EDIT:
You are getting exception cause Initial Catalog=DB_Name\Table_001. It should be Initial Catalog=DB_Name (only database name). Provide the table name in sql query to execute. Check some online tutorial to get more idea on the same.
You use . in data source only when you are connecting to local machine database and to the default SQL Server instance. Else if you are using different server and named SQL Server instance then your connection string should look like
using(SqlConnection sqlConnection = new SqlConnection())
{
sqlConnection.ConnectionString =
#"Data Source=Actual_server_name\actual_sqlserver_instance_name;
Initial Catalog=actual_database_name_Name;
Integrated Security=True;";
sqlConnection.Open();
}
In case you are using local machine but named SQL Server instance then use
Data Source=.\actual_sqlserver_instance_name;
Initial Catalog=Actual_Database_NAME;Integrated Security=True"
using System.Data.SqlClient;
Then create a SqlConnection and specifying the connection string.
SqlConnection myConnection = new SqlConnection("user id=username;" +
"password=password;server=serverurl;" +
"Trusted_Connection=yes;" +
"database=database; " +
"connection timeout=30");
Note: line break in connection string is for formatting purposes only
SqlConnection.ConnectionString
The connection string is simply a compilation of options and values to specify how and what to connect to. Upon investigating the Visual Studio .NET help files I discovered that several fields had multiple names that worked the same, like Password and Pwd work interchangeably.
User ID
The User ID is used when you are using SQL Authentication. In my experience this is ignored when using a Trusted_Connection, or Windows Authentication. If the username is associated with a password Password or Pwd will be used.
"user id=userid;"
Password or Pwd
The password field is to be used with the User ID, it just wouldn't make sense to log in without a username, just a password. Both Password and Pwd are completely interchangeable.
"Password=validpassword;"-or-
"Pwd=validpassword;"
Data Source or Server or Address or Addr or Network Address
Upon looking in the MSDN documentation I found that there are several ways to specify the network address. The documentation mentions no differences between them and they appear to be interchangeable. The address is an valid network address, for brevity I am only using the localhost address in the examples.
"Data Source=localhost;"
-or-
"Server=localhost;"
-or-
"Address=localhost;"-or-"Addr=localhost;"
-or-"Network Address=localhost;"
Integrated Sercurity or Trusted_Connection
Integrated Security and Trusted_Connection are used to specify wheter the connnection is secure, such as Windows Authentication or SSPI. The recognized values are true, false, and sspi. According to the MSDN documentation sspi is equivalent to true. Note: I do not know how SSPI works, or affects the connection.
Connect Timeout or Connection Timeout
These specify the time, in seconds, to wait for the server to respond before generating an error. The default value is 15 (seconds).
"Connect Timeout=10;"-or-
"Connection Timeout=10;"
Initial Catalog or Database
Initial Catalog and Database are simply two ways of selecting the database associated with the connection.
"Inital Catalog=main;"
-or-
"Database=main;"
I am using Entity Framework to access the data from my database. It's an MVC application and works fine locally. When I deploy the application on hosting (Parallels Plesk Panel, MS hosting) I get problems with accessing the SQL server instance. There are options in the cPanel which hold connection strings.
LocalSqlServer:
data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true
xContainer:metadata=res:///Models.x.csdl|res:///Models.x.ssdl|res://*/Models.x.msl;provider=System.Data.SqlClient;provider connection string=
When I upload the site xContainer is generated alone. I found the sql server's instance name and applied it to the data source. In my web.config file I am using the the xContainer. The code after this paragraph is what it seems logic to me to add after the connection string= in the xContainer.
I have tried this with various properties. Data source, initial catalog, and the other info are filled into the conn string (here I am showing only /).
Data Source=x;Initial Catalog=/;Persist Security Info=True;User ID=/;Password=/;MultipleActiveResultSets=True providerName=
The error I receive is that the sql server instance cannot be found. If I add the last piece of code to the container it tells that I don't have a providerName, After adding a providerName the string is deleted to the starting xContainer string:
metadata=res:///Models.x.csdl|res:///Models.x.ssdl|res://*/Models.x.msl;provider=System.Data.SqlClient;provider connection string=
The error I receive is that the **sql server instance cannot be found**.
So, what is the SQL instance name? :)
it maybe not ".\SQLEXPRESS" but ".\SQLEXPRESS2012" or even ".\MSSQLSERVER" or anything else.
You will need to Edit the Web.Config file manually. The ASP.NET Settings page will remove the providerName.
An example of a connection string using EntityClient is below. You can remove the metadata information if you're not using an Entity Model. You will notice the providerName is outside of the actual connectionString and is the reason you will need to edit the file manually.
connectionString="metadata=ModelInformation;provider=System.Data.SqlClient;provider connection string="data source=IP;initial catalog=DATABASE;User ID=USERNAME;Password=PASSWORD;multipleactiveresultsets=True;application name=EntityFramework"" providerName="System.Data.EntityClient"
Using VB6 and SQL Server 2005
I want to write a sql connection for connecting to other system sql server.
Code
ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI; Persist Security Info=False;Initial Catalog=STAR;Data Source=" & SName & ""
In SName - Am giving a Server Name
The Above connection code is working for the same system, Suppose I want to connect to other system database means
For example
I run the program in system A, the Database in system B. How to write a sql connection
Is possible with IP Address like SName = 192.12.12.1/System B
How to Write a connection string.
Need Code Help.
It depends on your network / DNS, you should be able to enter the machine name, you may also need a domain name.
SQL Server also has something called Named Pipes for accessing a SQL instance by it's name - do a google search on that...
Yes, you can use an IP address or a machine name but not both. The exact syntax is
Data Source=192.12.12.1; Initial Catalog=STAR; User Id=abc; Password=def;
In case, you have a trust established between the two servers, then you can replace the User Id and Password part by using Integrated Security=True just like you are doing if the database and program exist on the same machine.
Various types of connection strings are discussed here: http://connectionstrings.com/sql-server-2005
