What Is a Select Query?
A select query is the most common type of query. You use it to:
 * Retrieve data from one or more tables by using criteria that you specify and then to display the data in the order that you want.
 * Edit and update records in the datasheet of a select query (with some restrictions).
 * Group records and calculate sums, counts, averages, and other types of totals.
