Manipulate QueryDefs From VBA

QueryDefs are stored queries that reside in Access. These QueryDefs can be opened and modified using VBA. Sometimes it is useful to modify an original stored QueryDef by adding additional filters or modifying the SQL String.

For a technical explanation of QueryDefs, See QueryDefs

The code below shows how to modify an original stored query by adding a dynamic WHERE clause, then execute the modified version to append records to a table.
