If the identifier is also a keyword and used in a location where it could be that keyword (or any location even where the interpretation as a keyword rather than an identifier would be absurd and you are using a particularly stupid parser); it starts with an ill-conceived character for an identifier; or, it contains an embedded ill-conceived character, then you need to quote the identifier. Ill-conceived starting characters include most non-alphabetic characters except and underscore, and ill-conceived embedded characters include symbols that have other, usually terminal, meanings (space +-*/. etc). Other than those cases you need not quote identifiers. Identifiers are case preserving but case insensitive. -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
