Re: Reality check on PFs created as SQL TABLEs

Yes - primary key constraint is the way - the primary key "index" is embedded in the table/PF object.

CREATE TABLE xxxx (
xxx ....,
yyy ....,
CONSTRAINT "XXXX_PK" PRIMARY KEY (xxx),
...
);

But you can also create unique constraints directly in the table, and it will also create indexes, that are embedded in the table/PF object and create no extra objects.

Just to be sure:

There isn't some oddball extension to SQL that I'm not aware of, such
that you can create a keyed PF via an SQL CREATE TABLE statement, right?

(I just experienced what I'd thought was a weird asymmetry when
attempting to a LF as an SQL INDEX with a descending key; it turned out
that I'd misspelled "DESC," and SQL was treating "DSC" as a field
rename. You learn something new every day. This has been a fun week so far.)
