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'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.
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 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 don't seem to be able to find a way to escape this hyphenated database name so that I can open a connection to it. The database name is EDMS-Lok and my code looks like this (ADOcon is an ADO connection object):
strConBase="DRIVER=SQL Server;SERVER=LOKDB;UID=secret;PWD=secret;APP=LokENG_TESTS;WSID=LOKSPEC1;DATABASE=[EDMS-Lok];Network=DBMSSOCN;Trusted_Connection=NO;
ADOcon.ConnectionString = strConBase
ADOcon.Open"
I've tried the database name without enclosing brackets. I've tried enclosing it in square brackets, curly brackets, parentheses, back-ticks, single quotes, double quotes, etc. I've tried backslash and exclamation points. I can't find a way to escape the database name so that I can connect to it.
The error message I get is:
Run-time error '-2147467259 (80004005)':
[Microsoft][ODBS SQL Server Driver][SQL Server]Cannot open database "[EDMS-Lok]" requested by the login. The login failed.
The database name and credentials are correct. I can access it if I omit the database name argument from the connection string, and then use the fully qualified name in my SQL statements (i.e. SELECT * FROM [EDMS-Lok].dbo.tablename)
However, I really don't want to do this, as I'm trying to use modular code that does the same actions on multiple databases. What I want is to open the connection to one database, run some SQL procedures, close the connection, then open a connection to another database and run the same SQL procedures. Lather, rinse, repeat.
Also, before someone asks, I do not have the option of changing the database name.
As a test, I used the exact same connection string to connect to another database on the server that did not have a hyphenated name and it worked without error, so I'm pretty sure it's the stupid hyphenated name that is the problem.
I could not get this to work the way I wanted to through an ODBC connection using the MSDASQL provider.
I ran some tests and I seem to be able to connect through OLE DB using the SQLOLEDB provider. So, I think I will just go back and modify the existing code to use an OLE DB connection.
Using OLE DB, I've found I can leave the database name un-escaped, i.e. INITIAL CATALOG=EDMS-Lok; or I can escape using double quotes, i.e. INITIAL CATALOG="EDMS-Lok";. Square brackets however threw an error when I tried them, so for now I will stick to double quotes or un-escaped database names.
Thanks!
I want to connect to a SQL Server database without using DSN. I'm receiving an error when trying to connect to said database. The error is
Run-time error '-2147467259 (80004005)': [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
My connection string looks like this:
"ODBC;DRIVER=SQL Server;SERVER=lokdb; UID=secret;PWD=secret;APP=Microsoft Open Database Connectivity;WSID=" & Environ$("COMPUTERNAME") & ";Network=DBMSSOCN;Trusted_Connection=Yes;DATABASE=EDMS-Lok"`
I am able to connect to the default database on the server with the credentials specified if I remove the DATABASE=EDMS-Lok parameter from the connection string, however I don't then seem to be able to "find" the EDMS-Lok database. E.g. if I try using
SELECT * FROM EDMS-Lok.dbo.eng_dwg
I get an error message
Run-Time error '-2147217900 (80040e14)': [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near '-'
(eng_dwg is a valid table)
When I connect without specifying a database, the .DefaultDatabase property of the ADO connection object returns "020" which I don't even see as an available database on that server??
When connected, if I use SELECT name FROM sys.databases I'm able to get a list of the databases available. They are:
010
100
500
EDMS-Lok
Master
msdb
MSLLockDB
pubs
tempdb
I got it working using DSN, but I don't want to use DSN.
Not sure what is wrong here??
I would say the problem is that you mix up the authentication models. You provide user + password but also you have configured trusted connection = yes. I'm not sure how ADO works in that case but I would assume that it doesn't use the configured user and connects with the windows account. Delete the trusted connection parameter in the connection string and try again.
OK, credit for this answer should go to Dee and Sam who commented on the original question, however I can't mark a comment as the answer, so here it is:
Needed to wrap the database name in square brackets [ ] ... like this DATABASE=[EDMS-Lok] - (credit to DEE)
I first tried wrapping the database name in the connection string i.e. DATABASE=[EDMS-Lok] and this did not work (same error). However, if I connect without specifying the database, I'm able to access the table using SELECT * FROM [EDMS-Lok].dbo.eng_dwg
It didn't work in the connection string because the string is not T-SQL code. To get it to work, you may need to figure out how to escape the dash character. – (credit to SAM)
I've tried single and double quotes, backslash, square brackets, parentheses and curly brackets and nothing seems to work to escape the hyphen in the database name within the connection string. But, since I can now access the database and the tables I need, which was the original question, I wanted to mark it as answered.
