Karl is right -- but IF the text field happens to be the primary key of the table, then Access will return the records in that order by default. This behavior is purely arbitrary on Access's part, because officially a table is an unordered "bag of records", but that's what Access does if there is no reason to return the records in any other order.
If your table has some other primary key, then this fact won't help you. And if the field isn't suitable as a primary key -- for example, if it can't be counted on to be unique -- it won't help, either. But if your table currently has *no* primary key, it certainly should, and it may be that this text field would be suitable.
