Deprecated

as a consequence of AbstractSqmSelfRenderingFunctionDescriptor being deprecated. See corresponding docs for further information.

The timestampadd() or dateadd() function has a funny syntax which accepts a TemporalUnit as the first argument, and the actual set of accepted units varies widely. This class uses Dialect#timestampaddPattern(TemporalUnit, TemporalType, IntervalType) to abstract these differences.
