I have a table with an autonumber field as the key. I also have a date field in this table. I would like to sort my records by the date and have them appear in the form that way. As at now they look just mixed up. Help appreciated.
It's more than a good idea - it's a best practice. Having queries as the RecordSource to a form allows you to restrict the amount of records that your form displays. The more records your table has then the slower, eventually, your form will be when loading. Selecting only the relevant data (and sorting) it ensures your forms will load faster and non-necessary data is not available for display/manipulation.
If it's just a query to sort the dates then you don't need to update anything. Actually, what do you mean "update the table" - that sounds sinister to me?
