Sorry for asking stupid questions...
I can't remember which settings in MS SQL define the behaviour of this comparison:
select * from table where 'Anna ' = 'Anna'
to be TRUE. Both strings are different because the first contains trailing blanks.
How to change it to return FALSE what is my expected value?
You may be thinking of SET ANSI_PADDING, but that applies to how
strings are stored in tables, not how they are compared. SQL Server
ignores trailing blanks for non-Unicode data:

It would be useful to know the data types of the columns/variables
you're working with, but one possible query to get only exact matches
(on the basis of the length of the string) might be this:
select *
from table
where column = 'Anna' and
datalength(column) = datalength('Anna')
