Answer 1

There is a problem with your parameter declaration: you are trying to use the same param for shelfId and dateTime.

The declaration of parameters for the between case shoudl probably be between '?2' and '?3.

Please note the correct syntax (use ?1 instead of 1?):

Input parameters are designated by the question mark (?) prefix followed by an integer. For example: ?1.
