Class H2ArraySortFunction

java.lang.Object

org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor

org.hibernate.query.sqm.function.AbstractSqmSelfRenderingFunctionDescriptor

org.hibernate.dialect.function.array.AbstractArraySortFunction

org.hibernate.dialect.function.array.H2ArraySortFunction

All Implemented Interfaces:

FunctionRenderer, SqmFunctionDescriptor

public class H2ArraySortFunction
extends AbstractArraySortFunction

H2 requires a very special emulation, because unnest is pretty much useless, due to https://github.com/h2database/h2database/issues/1815. This emulation uses array_get, cardinality and system_range functions to achieve array sorting.
