rlm_sql does recursive xlat, all xlat expansions in the SQL query are
done before the query string is passed off to the SQL libraries. The
xlat parser is just looking for a string bounded by %{ }.
Your query should be:
%{sql:SELECT disctime.time FROM `disctime` WHERE disctime.user =
'%{User-Name}'}
It's not a problem in FreeRADIUS it's a problem in your SQL syntax :)
