Exam TDA-C01 topic 1 question 28 discussion

USERNAME() is a built-in Tableau function that returns the user's Tableau login name (usually their email or AD name, depending on setup). Comparing it to [Tableau_User_Name] creates a boolean calculated field that’s TRUE only for rows belonging to the logged-in user. You can then drag this calculated field to the data source filter to restrict data at the source level.

This is the way we do it in our company

Most be C. This is because A is comparing a boolean against a string with the = operator, the ISFULLNAME function can't accept fields. B is comparing name field with tableau_user_name which doesn't make any sense. And D is comparing the Name with the USERNAME() function which returns the current username, which is an email address for tableau server and not the full name of the user.

It is C (it is not A because the ISFULLNAME() argument is a text and can't be a field).

It is the correct answer since it will return Boolean value

Returns TRUEwhether the person currently using Tableau is a member of a group matching the given string. Returns FALSEif they are not a member, and NULLif they are not logged in.

It's C because isfullname() fuction can't use feild
