CREATE TABLE session (
sid varchar(255) PRIMARY KEY,
you don't need the UNIQUE constraint, since it is implicit in
PRIMARY KEY. A unique constraint on a single field can be
expressed by
field type UNIQUE
If a combination of fields is the primary key, you can use
CREATE TABLE foo (
f1 TEXT NOT NULL,
f2 TEXT NOT NULL,
...,
PRIMARY KEY (f1,f2)
);
