With Microsoft Jet queries, you can define formal parameters. Formal parameters represent unknown values that must be supplied by the user running the query or the program executing the query. A query’s formal parameters are represented by Parameter objects in the Parameters collection of a QueryDef object. This collection is particularly useful when you execute a parameter query in code and have to supply values for the query parameters at run-time.
