Queries in ACESS (QBE) : Can we use more than 3 Tables?

AI Thread Summary
It is possible to query more than three tables in Access, provided there is a common field to link them. Users may encounter redundancy when querying multiple tables, which can complicate results. To effectively perform a query, it's essential to understand the contents of the tables and the specific information needed from the query. Each pair of tables must be related through a common attribute for the query to work correctly. Properly structuring the query can help eliminate redundancy and yield the desired results.

You need to give us more information, such as: what are the contents of the tables and what do you want the query to answer.
 
Thanks, so in principle it is possible to query more than two databases ? Do we need any pair or any n-ple of databases to be related?

Yes. In Access terminology the data are contained in tables while a database contains tables, queries, forms etc. The only requirement for multi-table queries is a field that can be used to link tables pairwise.
