Explain the term- Query.
Queries are used to repossess and show specific records in a table. They can also be used to show specific fields of specific records, which meet the condition specified. A query displays a subset of all or exact fields and records in a table. When a change is made to the data, which is shown by the query, this change is reflected in the table also. Because of this dynamic relationship among the query and the tables, the subset of the data displayed by the query is called a Dynaset.
