@Earthshine is perfectly right.
Always retrieve the only columns you need and if you do require them all, then list them explicitely in the order that best fits processing in your programming language.
Why?
Simply because if ever you need to reorder, add or remove some column(s) in a table, then all your applications using this table will need rewrite, testing, release, along with a way to cope with old and new designs (think upgrade and backups).
Also, double quotes are used in SQL for schema names (databases, tables, views, indices, columns, aliases), while single quotes are used to enclose string values.
