This is an invalid syntax in IB. You have two options:

1.- Normal select statement. You can do a sub-select for each field that you
want to change:
update table1
set column1 = (select column3 from table2
where table2.column2 = table1.column2)

2.- Write a stored proc, this construction is usually the fastest. This is
the body:
FOR select table1.rdb$db_key, table2.column3
from table1 join table2 on
table1.column2 = table2.column2
INTO :dbk, :col3
DO
update table1 set column1 = :col3
where rdb$db_key = :dbk;

If you feel confused by this syntax, go to my site and read about
"rdb$db_key" in the "documentation" section.
