guys,
sorry my query is like so:
update a
set number = any ( select number from b where a.name=b.name )
where number is null;
simplified table a:
sn | number | name
----------------------------------
1 | 101 | john
2 | null | mary
3 | 127 | mark
4 | null | jane
5 | 133 | matt
simplified table b:
sn | number | name
----------------------------------
1 | 101 | john
2 | 967 | mary
3 | 127 | mark
4 | 965 | jane
5 | 133 | matt
so basically trying to get "number" from "b" to "a" where their "name"s match.
also "... number in (...) ..." throws error (syntax error at or near "in").
thks, jzs
