Union Query in Microsoft Access

Our Union Query Example demonstrates a method used to add additional choices to drop down lists such as New or All.

Using the New choice in a combo box makes the user interface a little more user friendly.  This feature can be combined with the standard not in list event handler for adding new items to the list.  This is perhaps the simplest of union queries.

Generally union queries are used to bring together records from different data tables.  The fields in the tables do not need to be of the same data type but you must have the same number of fields selected from each table.  You can use the SQL union command to bring data together from many tables, not just two.
