Twenty things to do with Access database queries - help and examples

Databases will be very limited in scope without an understanding of queries. A query can almost always enhance a  table and improve the presentation of the data, either by sorting, joining, updating, grouping or limiting fields and records.

These pages contain examples of Access database queries that are designed to indicate the scope of what can be achieved with relatively little experience. This guide does not talk you through step by step on how to use the Access program. A basic understanding of database design and creating a query is assumed.
