A query is a request for data or action on data. Queries can be used to answer questions, perform calculations, combine data from different tables, or add, change, or delete table data. Select queries are used to retrieve data or make calculations, while action queries add, change, or delete data. Common examples of queries include finding the maximum value in a column and calculating visits per day.

You can use a query to answer a simple
question, to perform calculations, to combine
data from different tables, or even to add,
change, or delete table data. Queries that you
use to retrieve data from a table or to make
calculations are called select queries. Queries
that add, change, or delete data are called
action queries.
