With the Data Explorer, when using "strongly-typed" integer parameters in the form of
##VariableName:int##, you can't enter negative values. When attempting to do so, you get an error message:
Expected value of VariableName to be a int!
You can try this for yourself; I noticed this while composing a simple "worst answers" query with a user-supplied cutoff score. Attempting to enter negative scores causes this error, while values of 0 and above work. (Don't try this at
home Stack Overflow, kids!)
