unlang question

[Norbert Wegener]

Something like
if ("%{sqlnastype:SELECT Value from radcheck where UserName = 
'%{User-Name}' and otherconditions}" == 'bla' )
works,
whereas I have problems
with:

if ("%{sqlnastype:SELECT Value from radcheck where UserName = 
'%{User-Name}' and  other conditions.. " is not null )

Am I doing something wrong or is "is not null" not (yet) implemented?
