Class H2ArrayRemoveFunction

java.lang.Object

org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor

org.hibernate.query.sqm.function.AbstractSqmSelfRenderingFunctionDescriptor

org.hibernate.dialect.function.array.AbstractArrayRemoveFunction

org.hibernate.dialect.function.array.H2ArrayRemoveFunction

All Implemented Interfaces:

FunctionRenderer, FunctionRenderingSupport, SqmFunctionDescriptor

public class H2ArrayRemoveFunction
extends AbstractArrayRemoveFunction

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, array_length and system_range functions to roughly achieve the same.
