My Windows account has administrator rights on a local SQL Instance. I am able to change the password to SA user but when I try to login using SA with SQL Server authentication mode it gives me error. I am trying to access a local database.
Can somebody please help me to set the password and login to the local SQL using SQL authentication mode?
To set the sa password
In Object Explorer, connect to an instance of Database Engine.
On the Standard bar, click New Query.
Copy and paste the following example into the query window and click Execute. The following example enables the sa login and sets a new password.
