Updating Tables
I am a new use to Access...I created a table with several
fields and several sub tables based on those fields. When I add records to my original table, how is that information updated in the subtables? |

Normally you would have "subtables" related one to many to your main table; there would be a Primary Key field in your main table, joined to a matching datatype "foreign key" field in the related table. The related table would have zero, one, or many records with that linking field. If there is no data in the related table, there's just no data in it - and no need to create an empty "placeholder" record. What are the structures of the tables? How are they related (in the relationships window)? Why do you feel that you need to "update data in the subtables" - what data? John W.
