Examples of org.hibernate.dialect.function.SQLFunction

org.hibernate.dialect.function.SQLFunction
Provides support routines for the HQL functions as used in the various SQL Dialects Provides an interface for supporting various HQL functions that are translated to SQL. The Dialect and its sub-classes use this interface to provide details required for processing of the function. @author David Channon
