    摘要： 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).

    摘要： 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.

    摘要翻译： 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。

    摘要： Embodiments extend the relational model and query language to recognize features of tables and higher level entity-relationship models (ERMs). Extension language is implemented in the data design language (DDL) to incorporate tables, entities (and views) having custom-defined/semantic structure, rather than being limited to primitive types (e.g. flat tables as in standard SQL). The extension language includes an indication that a query is to include all active elements for each table extension or entity extension that is active. The extension language can be chained to extend a table or entity that has been extended.

    摘要： A technique is described for generating error buffer that includes errors from both a program and event handlers called by the program. A program in an event-driven environment triggers an event. In response to the triggered event, the program calls event handlers related to the event. The event handlers are executed and error messages generated during the execution are stored in a local error buffer. Upon completion of the event handlers, the local error buffers are returned to the program and the program merges the local error buffers with an error buffer associated with the program.

    摘要： Embodiments extend the relational model and language of standard SQL, to recognize features of higher level entity-relationship models (ERMs). Annotation language is implemented in the data design language (DDL) to incorporate tables and entities Using DDL, annotations are typed structures of metadata. Annotations may be used for types, entities and elements. In the query language (QL), annotations may be added to the standard QL. A reflection program may use the metadata of the annotation language for reflection on the tables or entities.
