For example: SELECT * FROM people WHERE fname = 'James'; or SELECT * FROM price WHERE msrb BETWEEN 50 AND 100; Now is it correct to say that in PostgreSQL or ANSI SQL in general I should use 'single quotes' when the condition is strictly a numerical data type value and everything else should be inside 'single quotes'? -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
