READ action gives you the columns that the statement needs to read, for any reason. They may be mentioned in SELECT, WHERE, ORDER BY, LIMIT, ON and other clauses - whenever an expression is allowed by the syntax. Seems to be just what you need. -- Igor Tandetnik _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
