A query that copies or changes data. Action queries include append, delete, make-table, and update queries. Delete and update queries change existing data; append and make-table queries copy existing data. In SQL, these are referred to as DML queries and consist of the keywords DELETE, INSERT, and UPDATE. Microsoft� Jet supports the keyword SELECT INTO, which is also considered a DDL query. In contrast, select queries return data records. An SQL pass-through query may also be an action query.
