Class AnsiDialect

  • All Implemented Interfaces:
    SqlDialect
    public class AnsiDialect
extends Object
implements SqlDialect
    Represents the support from SQL ANSI that are queries cross-platform. Represents a dialect of SQL implemented by a particular RDBMS. Subclasses implement Hibernate compatibility with different systems. Subclasses should provide a public default constructor that register a set of type mappings and default Hibernate properties. Subclasses should be immutable.
