Examples of javax.jdo.Query.declareParameters()

javax.jdo.Query.declareParameters()
Declare the list of parameters query execution. The parameter declaration is a String containing one or more query parameter declarations separated with commas. Each parameter named in the parameter declaration must be bound to a value when the query is executed.
The String parameter to this method follows the syntax for formal parameters in the Java language. @param parameters the list of parameters separated by commas.
