Hello Maxim,

f> select sqr(T.Val) from T where ID=2;
No. But why don't you use "in-line" expression (I mean SELECT
T.Val*T.Val...) or a user-defined function for that? Unfortunately,
UDFs in the FB distributive haven't such function (probably because of
easiness of "in-line" implementation), but maybe some free UDF libs
include it. Or you may create you own UDF lib.
