摘要： Various embodiments of the present invention are direct to the utilization of Blob Handles (BHs) which are an internal representation of a large value. BHs are immutable and stateless references to a large data object. The structure of a BH contains enough information to return an ILockBytes interface in order to provide access to the corresponding large data block, and a BH can also return information regarding its own lifetime description. A BH can be completely described using (a) a pointer to the beginning of BH data and (b) the byte-length of the BH.

摘要翻译： 本发明的各种实施例直接利用作为大值的内部表示的Blob句柄（BH）。 BH是不可变的和无状态的引用大型数据对象。 BH的结构包含足够的信息来返回ILockBytes接口，以便提供对相应的大数据块的访问，并且BH还可以返回关于其自身寿命描述的信息。 可以使用（a）指向BH数据的开始的指针和（b）BH的字节长度来完全描述BH。

摘要： Various embodiments of the present invention enable functions, procedures, and triggers to be written in any of the .NET languages and executed by the RDBMS. User code can access data from the local or other SQL servers using the SQL Programming Model and both the SqlServer or SqlClient implementations respectively. Moreover, to improve upon the previous extensibility mechanism, a set of APIs (commonly known as “the in-process provider” or “inproc provider”) is utilized to provide efficient and easy to use data access while running inproc, a data access API that is an implementation of the ADO.net programming model.

摘要翻译： 本发明的各种实施例使功能，过程和触发器能够以任何.NET语言编写并由RDBMS执行。 用户代码可以分别使用SQL编程模型和SqlServer或SqlClient实现访问来自本地或其他SQL服务器的数据。 此外，为了改进以前的可扩展性机制，使用一组API（通常称为“进程内提供程序”或“inproc提供程序”）来在运行inproc时提供高效且易于使用的数据访问，数据访问API 这是ADO.net编程模型的实现。

摘要： A technique for updating collection-valued and other complex structured columns in a nested table using a nested extension of an UPDATE statement that uses syntax and semantics to modify collection-valued columns in a way that is analogous to the syntax and semantics of the UPDATE statement that is used to modify scalar-valued columns of the table (called the outer UPDATE). Using the same syntactic and semantic constructs as the table at the outer level allows an existing implementation that processes modifications to relational tables to reuse its implementation techniques for processing outer updates to modify collection-valued columns as well. The UPDATE extensions enable the specification of updates to nested collections embedded at arbitrary levels of depth in the object model. The new syntax is embedded inside the outer UPDATE statement in a way that parallels the structure of the data itself and thus maps more directly to the user's conceptual model of the data. The method for implementing the UPDATE extensions uses a change descriptor, which is a data structure that aggregates substantially all changes, both scalar and collection-valued into a single value that can be applied to the changed collection-valued column. This technique can also be used for modifications to other kinds of complex-structured columns such as objects or xml. The change descriptor includes hierarchical information for the cell, thereby enabling efficient application of multiple updates at various granularity levels in a single operation and enabling the implementation of efficient index maintenance algorithms by updating only the indexes affected by the UPDATE operation and updating only those index rows that were affected by the UPDATE operation.

摘要翻译： 一种用于使用UPDATE语句的嵌套扩展来更新嵌套表中的集合值和其他复杂结构化列的技术，该语法使用语法和语义来以类似于UPDATE语句的语法和语义的方式修改集合值列 用于修改表的标量值列（称为外部UPDATE）。 使用与外层相同的句法和语义结构允许处理对关系表的修改的现有实现，以重用其实现技术来处理外部更新以修改集合值列。 UPDATE扩展使得能够对对象模型中嵌套在任意深度深度的嵌套集合进行更新。 新的语法以外部UPDATE语句的方式嵌入到数据本身的结构中，从而更直接地映射到用户的数据概念模型。 实现UPDATE扩展的方法使用一个更改描述符，该描述符是一个数据结构，它将基本上所有的变量（标量和收集值）聚合成一个可以应用到更改的收集值列的值。 此技术也可用于修改其他类型的复杂结构列（如对象或xml）。 更改描述符包括小区的分层信息，从而能够在单个操作中在各种粒度级别高效地应用多个更新，并且通过仅更新受UPDATE操作影响的索引并仅更新那些索引行，从而实现高效的索引维护算法 受UPDATE操作的影响。

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.

Preferably, the database system stores metadata about the user-defined type for subsequent use in creating instances of the type.

摘要： Several embodiments of the present invention are directed to systems and methods for extending the UDT framework of an extended relational data store (ERDS) to include support for unordered collections (multisets) and ordered collection (lists). More specifically, several embodiments of the present invention use an UDT infrastructure, CLR generics, and a new UNNEST operator to create and utilize a special type abstraction for collections that is simultaneously a scalar and a relation. As a scalar, this collection type can be processed by all parts of the data store engine that understand scalars (including but not limited to the client stack) and, as a relation, this collection type is queriable like any other type of relation.

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 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.
