I designed a database for our small company ten years ago. In my order table I have the Order No. field as the primary key and it is a text data type. Orders started at 1001 and we have just hit order no 10000. Instead of falling after 9999, order no 10000 is back at the top before 1001. I thought changing the field type to number would allow it to continue in a consecutive order, but it won't allow me to change it, it says I must remove the relationships with other tables.
I don't know enough about Access to do that. Can anyone help?
