ASA does not require to drop constraint before dropping tables, and DROP statement syntax used by Hibernate to drop constraint is not compatible with ASA, so disable it. Comments matchs SybaseAnywhereDialect from Hibernate-3.1 src

Namespace:  NHibernate.Dialect
Assembly:  NHibernate (in NHibernate.dll)

Syntax

Visual Basic (Declaration)
Public Overrides ReadOnly Property DropConstraints As Boolean
C#
public override bool DropConstraints { get; }
Visual C++
public:
virtual property bool DropConstraints {
	bool get () override;
}
JavaScript
function get_dropConstraints();
