public Class H2ArrayRemoveFunction

extends AbstractArrayRemoveFunction
Class Inheritance
Imports
java.util.List, org.hibernate.query.ReturnableType, org.hibernate.sql.ast.SqlAstTranslator, org.hibernate.sql.ast.spi.SqlAppender, org.hibernate.sql.ast.tree.SqlAstNode, org.hibernate.sql.ast.tree.expression.Expression

Deprecated

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

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.
