can anybody explain me the syntax of Create Table documentation??
CREATE [ TEMPORARY | TEMP ] TABLE table (
column type
[ NULL | NOT NULL ] [ UNIQUE ] [ DEFAULT value ]
[ column_constraint_clause | PRIMARY KEY } [ ... ] ]
[ , ... ]
[ , PRIMARY KEY ( column [, ... ] ) ]
[ , CHECK (condition) ]
[ , table_constraint_clause ]
) [ INHERITS ( inherited_table [, ... ] ) ]
i don't understand what the curly brace means after PRIMARY KEY (where is
the other matching brace? ). It must have something to do with the fact
that a 'column type' pair ( with options ) can occur more than once, but is
this syntax right?
i also don't understand what the [ ... ] and [, ... ] means. I do know that
brackets denote options and | alternatives.
