问题
I am trying to open an SQL data connection using a PowerShell script and my password contains a $ sign:
$cn = new-object system.data.SqlClient.SqlConnection("Data Source=DBNAME;Initial Catalog=Catagory;User ID=User;Password=pass$word;")
When I try to open a connection it says:
Login failed
回答1:
Escape it by using backtick (`) as an escape character for the dollar sign ($).
Also, try to enclose the statement in single-quotes instead of the double-quotes you are using now.
