    • Techniques are described for expressing a constraint in a host language. A constraint can be defined in the host language as an event handler. The event handler can be registered to a built-in event associated with an object of the database that the constraint is intended to validate. When the object triggers the built-in event, the event handler is called to execute the constraint. Exemplary built-in events include onSave (trigger the event when the object is saved), onValidate (trigger the event when an explicit call to validate the object is detected), onInsert (trigger the event when the object is inserted), onUpdate (trigger the event when the object is updated), and onCheckBeforeSave (trigger the event when the object is checked prior to saving).
    • 描述用于在主机语言中表达约束的技术。 约束可以在主机语言中定义为事件处理程序。 可以将事件处理程序注册到与数据库的对象相关联的内置事件,该约束将用于验证。 当对象触发内置事件时,将调用事件处理程序来执行约束。 示例性的内置事件包括onSave(当保存对象时触发事件),onValidate(触发事件,当检测到验证对象的显式调用)时,onInsert(触发插入对象时的事件),onUpdate(trigger 当对象被更新时的事件)和onCheckBeforeSave(在保存之前检查对象时触发事件)。

    • Disclosed are techniques employed alone or in combination, to further enhance a database language and improve conciseness and comprehensiveness of query statements in application code. Embodiments may build upon an initial extension of database language to accommodate concepts of entity-relationship models (ERMs). That initial extension may include entities with structured types, and named associations. One technique modifies SQL to allow the SELECT command to specify element path expressions based upon a relationship (e.g. named associations between ERM elements). Another technique modifies SQL to introduce filter expressions suffixed to associations within path expressions, thus improving adherence to the principle of locality within query statements. Yet another technique allows a shorthand to “factor out” association path prefixes, thereby avoiding lengthy lists of path expressions in order to read several elements from the same nested structure or a same target entity behind a single association. Other techniques simplifying database querying are also disclosed.
    • 公开的是单独使用或组合使用的技术,以进一步增强数据库语言,并提高应用程序代码中查询语句的简洁性和全面性。 实施例可以基于数据库语言的初始扩展来构建,以适应实体关系模型(ERM)的概念。 该初始扩展可能包括具有结构化类型的实体和命名关联。 一种技术修改SQL,以允许SELECT命令基于关系(例如,ERM元素之间的命名关联)来指定元素路径表达式。 另一种技术修改SQL来引入路径表达式中的关联后缀的过滤器表达式,从而提高对查询语句中局部性原则的遵守。 另一种技术允许“缩小”关联路径前缀的简写,从而避免路径表达式的冗长列表,以便从单个关联后面的相同嵌套结构或相同目标实体读取几个元素。 还公开了简化数据库查询的其他技术。
