I have a database that contains employee information. Each employee belongs to a Business Unit and that Business Unit is described by a number and name. For example: 12345678 and Human Resources. I'm using Access Project and my tables are stored on an SQL Server. I have stored procedures. One procedure builds a table for these Business Units by selecting the distinct values from my employee table. I have entered a union statement to insert an "ALL" record into the Business Unit table with a record 99999999 for the BU number and * for the BU name. However when I run a query and reference the ALL record, my query is not returning any rows. I'm thinking it is because no one actually has 99999999 as their business unit number. To select the Business Unit I have an Input Parameter defined as the choice in a combo box on a form. How do I define the Input Parameter to recognize the 99999999?
