Package org.hibernate.dialect.function

Class TimestampaddFunction

java.lang.Object

org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor

org.hibernate.query.sqm.function.AbstractSqmSelfRenderingFunctionDescriptor

org.hibernate.dialect.function.TimestampaddFunction

All Implemented Interfaces:

FunctionRenderer, FunctionRenderingSupport, SqmFunctionDescriptor

Direct Known Subclasses:

IntegralTimestampaddFunction

public class TimestampaddFunction
extends AbstractSqmSelfRenderingFunctionDescriptor

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.
