Question

I have installed SQL Server 2005 in Windows Authentication, now I want to change it to SQL Authentication.
However, I cannot reinstall SQL SERVER and Management again, because it will lose the data in it.
Also I want to know what changes do I need to make in my Connection class to open connection, as my current is

public SqlConnection con= new sqlConnection("server=.\\SQLEXPRESS;database=Restaurant;integrated security=sspi");

Just need to ask one more thing, I can see my database in WIndows Auth and in SQL auth, so how can i change, so that any other user need to login before it peeps into my database. thanks

Answer 1

To use SQL Server authentication, change the line:

public SqlConnection con= new sqlConnection("server=.\\SQLEXPRESS;database=Restaurant;integrated security=sspi");

to

public SqlConnection con= new sqlConnection("server=.\\SQLEXPRESS;database=Restaurant;user id=#USERID#;password=#PASSWORD#;Trusted_Connection=False");

Where “#USERID#” and #PASSWORD# are the specific User ID and Password respectively
