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.
