问题
I'm new to SqlServer, right now I have SqlLocalDb installed to work locally. Good, but I can see two connection strings typically and both works:
Data Source=(localdb)\v11.0;Integrated Security=true;
and
Server=(localdb)\v11.0;Integrated Security=true;
What exact difference is there between the two?
回答1:
For the full list of all of the connection string keywords, including those that are entirely synonymous, please refer to the SqlConnection.ConnectionString documentation:
These are all entirely equivalent:
- Data Source
- Server
- Address
- Addr
- Network Address
回答2:
... There is no difference between Server and Data Source as they represent the same thing for SQL Server : the full name of the SQL Server instance with the syntax "MyComputerName\MyShortInstanceName" , potentially including the port used by the SQL Server instance to communicate.

They are synonymous - you can use either one.
That is - as far as the framework is concerned, they are the same.
回答4:
My favorite set up is one that doesn't contain any spaces. In the simplest form, one has to provide four values - the URL, the container, the user and the credential.
- server
- database
- uid
- pwd
So a connection string looks like this.
server=stuffy.databases.net;database=stuffy;uid=konrad;pwd=Abc123(!);
