I understand how to update the report to allow me to send 'All' to a text parameter. That's not really what i'm looking for. I am looking to see if there is built in functionality for the 'Select All' of a multi value parameter. In that instance sending 'All'
would just error saying that it isn't a valid selection.
No there is no magical string. You must adhere to the language constructs.
Anyway, I use the approach explained above in SSRS and it works great. Keep in mind, I'm not recommending using the work "All". The code sample was intended to illustrate how to take advantage of a logical OR to shortcut a filter.
false OR false = false
false OR true = true
true OR false = true
true OR true = true
