Dear all,
it seems that sqlite does not allow update statements of this kind:
UPDATE table_1 SET (field_a, field_b, field_c, field_d) = (
SELECT field_a, field_b, field_c, field_d FROM table_2 WHERE …
)
WHERE ....
I succeeded only with
UPDATE table_1 SET
field_a = (SELECT field_a FROM table_2 WHERE … ),
field_b = (SELECT field_b FROM table_2 WHERE … ),
field_c = (SELECT field_c FROM table_2 WHERE … ),
field_d = (SELECT field_d FROM table_2 WHERE … )
WHERE ....
and that's may be not th optimal way, dealing with tables of a dozen of
fields ....
thanks in advance
Geraldo
