if table A has a primary key
and table B has a field with a foreign key on A.primary
does that field in table B also need an index or will it use the index for the
primary key?
I remember reading years ago that Firebird would compile multiple indexes based

eg
Table1 (
field1,
field2,

SL That approach is not true is 100% of cases. It depends on many factors:

1024, and _restart_ Firebird.
What else can I test?
