public class TimestampdiffFunction extends AbstractSqmSelfRenderingFunctionDescriptor
Thetimestampdiff()
ordatediff()
function has a funny syntax which accepts aTemporalUnit
as the first argument, and the actual set of accepted units varies widely. This class usesDialect.timestampdiffPattern(TemporalUnit, TemporalType, TemporalType)
to abstract these differences.
