    摘要： The present invention the is directed to systems and methods for hosting the CLR in a DBMS in order to achieve reliability, scalability, security, and robustness for enabled DBMS programming features. Integrating the CLR with a DBMS enables programming features in the database such as stored procedures, functions, triggers, types, and aggregates to be written in any of the programming languages that are compiled into IL code supported by the CLR. For the various embodiments of the present invention, the CLR is hosted inside the DBMS and, instead of making requests directly to the server operating system, the CLR instead interfaces with the DBMS via DBMS APIs for such requests, and only the DBMS directly interfaces with the server operating system to access the server.

    摘要： A system and method are provided for modeling structured, semi-structured, and unstructured data all within a single instance of a user defined type (UDT) within a database store. In particular, the XML data model is extended to fields of a UDT. As a result, the properties of the XML data model—such as document order and document structure—can be preserved within instances of a UDT. Moreover, code representing object behavior (i.e., methods that can be invoked on an object in managed code) can be added to the UDT to operate on an XML field, as well as non-XML fields of the UDT. This enables a framework for adding business logic to XML data. The content model of the XML data can be optionally described using XML schema documents associated with the XML fields of the UDT.

    摘要翻译： 提供了一种系统和方法，用于在数据库存储内的用户定义类型（UDT）的单个实例中对结构化，半结构化和非结构化数据进行建模。 特别地，XML数据模型扩展到UDT的字段。 因此，XML数据模型的属性（如文档顺序和文档结构）可以在UDT的实例中保留。 此外，可以将代表对象行为的代码（即，可以在托管代码中的对象上调用的方法）添加到UDT以对XML字段以及UDT的非XML字段进行操作。 这使得可以将业务逻辑添加到XML数据中。 可以使用与UDT的XML字段相关联的XML模式文档来可选地描述XML数据的内容模型。

    摘要： A database system and method allows a user to write program code in a high-level programming language that implements a class that defines the structure of a user-defined type and methods that can be invoked on instances of the type. The class is then registered with the database system, which enforces a specific contract for user-defined types against the class. The contract comprises the following requirements. First, the class must specify one of a plurality of different formats for persisting instances of the user-defined type in a database store. Second, the class must be capable of returning a null value for the user-defined type. Third, the class must provide a method for converting the user-defined type to another type. Once these requirements are satisfied, the database system enables instances of the user-defined type to be created. A user-defined type can be used in all contexts where any other built-in type can be used. This includes defining columns of tables, declaring variables and parameters to functions and stored procedures, and evaluating expressions of the user-defined type in SQL queries and updates. Preferably, the database system stores metadata about the user-defined type for subsequent use in creating instances of the type.

    摘要： A database system and method allows a user to write program code in a high-level programming language that implements a class that defines the structure of a user-defined aggregate and methods that can be invoked on instances of the user-defined aggregate. The class is then registered with the database system, which enforces a specific contract for user-defined aggregates against the class. The contract comprises the following requirements. First, the class must specify one of a plurality of different formats for persisting instances of the user-defined aggregate in a database store. Second, the class must comprise a first method that can be invoked to initialize the computation of an instance of the user-defined aggregate, a second method that can be invoked to accumulate a plurality of values to be aggregated with the user-defined aggregate, a third method that can be invoked to merge an instance of the user-defined aggregate with another partial aggregation, and a fourth method that can be invoked to compute a final result of an instance of the user-defined aggregate. Once these requirements are satisfied, the database system enables instances of the user-defined aggregate to be created. Preferably, the database system stores metadata about the user-defined aggregate for subsequent use in creating instances of the aggregate.

    摘要： Multiple programming languages can be embedded and supported within a single source. Programs nested with syntax from a plurality of languages (e.g., C#, SQL, XML . . . ), among other things, enable users to avail themselves of advantageous aspects of different languages for particular tasks. Language services that provide language specific functionality including but not limited to formatting, intelligent assist, auto completion, and coloring, can be employed and switched between to afford support for their respective languages in a mixed language source program. Similarly, mixed language programs can be compiled with language specific services or systems such as parsers, scanners and the like to process corresponding code portions.
