Delete queries are used to delete large amounts of data quickly, or to regularly perform the same delete operations. A query can help you make sure that you are deleting the correct data and can be saved and then easily repeated. Like all other action queries you can't undo the effects of a delete query. However a delete query is much more dangerous than the other action queries because there is no way to get back the accidentally deleted data. Creating a delete query is no different than creating a select query. A select query displays the records that match your criteria, a delete query deletes those records.
