I just want to update the Owner and Responsible fields Thanks Assuming Owner is a text field you will need the single quotes.

The following code works fine for one field: UPDATE [Trip Registration] SET [Trip Registration].[Trip1 Confirm] = "C" WHERE (([Trip Registration].[Trip1 Coord])=True); but the problem is that I'd also like the same query to update two other fields (Trip2 Confirm and Trip3 Confirm) using the same kind of criteria.

That is, if Trip2 Coord is True, set Trip 2 Confirm to "C", and the same for Trip3. Try opening a new query and pasting this into your sql view.

When you need to update data from one table to another, consider the following rule: the data types for the source and destination fields must either match or be compatible.

Furthermore, when you update data from one table to another and use compatible data types instead of matching data types, Access converts the data types of those fields in the destination table.

I have multiple databases that contain recipe data used for machines. This will take hours unless there is an easier way.

Each machine has its own computer and access db installed.

Tip: Back up your database before you run an update query.

You cannot undo the results of an update query, and making a backup helps make sure that you can reverse your changes if you change your mind.

This db has multiple tables and each table has exactly identical field names. I have one field in 'x' amount of tables that need edited.

This field value is always in the first record of the tables that I need to change.
