I understand this. Try describe my problem with other words.
Is the VIEW an atomic (or compiled like a STORED PROCEDURE) thing?
I have a VIEW with 4 fields (FIELD1..4), 1 come from the "FROM table"
(FIELD1) and 3 from JOINs (FIELD2..4). If execute a SELECT FIELD1 FROM
... PLAN contains the JOINs. Why? If I write a SELECT manually not
include JOINs if not needed for the resulted fields, because want
maximum performance.
