The basic rule is that the result of any comparison involving a
NULL value (including comparing against another NULL) is NULL.

By itself, "sqlite" probably means SQLite version 2. Same concept as

I think with a virtual table all you can do is:
SELECT * FROM vtable WHERE x = 'a' UNION
SELECT * FROM vtable WHERE x = 'b'
Virtual tables cannot supply an index for WHERE clauses of the form
"x IN ('a', 'b')" or "x = 'a' OR x = 'b'" the way normal tables
can.

Shared cache mode does not apply to :memory: databases. It is not
