guys,
trying multiple updates without success like so:

update  a
set             number = any (  select number from b where a.number=b.number)
where   number is null;
>> 'syntax error at or near "any"'

subquery returns more than one row. using 8.1.
thks, jzs


If the subquery returns multiple values, which value do you want to set to the 'number' column. For each record there can be only one value for this column? 
The subquery has to return only one value such a query.

Show the tables structure, maybe there is a better column than the 'number' to join the 'a' and 'b' tables.
