Queries

A query is a way of applying various combinations of query components to tables and relations:

Queries are useful in that they allow you to apply their components all in one go, rather than having to individually apply each one. The outcome of a query is a table in its own right. The query table is live and so reflects the latest state of the table or relation on which it is based. Queries can be saved, thereby allowing you to apply them whenever you need to.

To apply a query you first need to have created a table in your database. You can create a query from Database Manager, and you can then apply it whenever you need to. Alternatively you can create a query while you are working in a table, and the query can then be applied immediately.
