Class H2ArrayRemoveIndexFunction
java.lang.Object
org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor
org.hibernate.query.sqm.function.AbstractSqmSelfRenderingFunctionDescriptor
org.hibernate.dialect.function.array.ArrayRemoveIndexUnnestFunction
org.hibernate.dialect.function.array.H2ArrayRemoveIndexFunction
- All Implemented Interfaces:
FunctionRenderer
,FunctionRenderingSupport
,SqmFunctionDescriptor
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.-
