9. The queries
Previous pageTable of contentsNext page
A query is used to interrogate a database in order to view, insert, modify or delete data. The query structure defines the data used.
A query can interrogate one or more data files.
The query editor allows you to easily create queries without programming.
Principle of queries
Remark: In programing, a query can be handled like a data file. Especially, it can be associated with a display control (a Table control for example) that will present the data returned by the query.
