Select user_name [User Name], first_name [First Name], last_name [Last Name]
Form tab_user
ORDER BY user_name
Select user_name [User Name], first_name [First Name], last_name [Last Name]
Form tab_user
ORDER BY User Name
Above are the two queries,
Is there any difference because of the user_name used instead of User Name
Is there something that should be taken care/worried when using something like this.
