In Microsoft Access, a query is used to retrieve specific information from one or more tables in a database. Queries can be used to filter and sort data, perform calculations, and combine data from multiple tables. They allow users to extract only the information they need, making it easier to analyze and work with the data in the database. Queries can also be saved and reused, making it easier to retrieve the same information multiple times.

A query in MS Access is a database object that allows you to retrieve and manipulate data from one or more tables in the database. Queries are used for a variety of purposes, including:
- Selecting data: Queries can be used to select specific rows and columns of data from a table. This is useful for creating reports, populating forms, or performing calculations.
- Sorting data: Queries can be used to sort data in a specific order. This can be useful for organizing data or finding specific records.
- Filtering data: Queries can be used to filter data based on specific criteria. This can be useful for finding specific records or excluding certain records from a report.
- Joining data: Queries can be used to join data from multiple tables. This can be useful for creating reports or performing calculations that require data from multiple sources.
- Updating data: Queries can be used to update data in one or more tables. This can be useful for making changes to a large number of records at once.
- Deleting data: Queries can be used to delete data from one or more tables. This should be used with caution, as deleted data cannot be recovered.
