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： The SQL Algebrizer of the present invention comprises a plurality of algorithms to “algebrize” SQL Trees to QP Algebra using an approach that is more consistent and much more efficient than typical algebrizers. More specifically, the Algebrizer of the present invention processes a SQL Tree using a reduced number of recursive depth-first passes by performing multiple operations in a single pass. Furthermore, the Algebrizer of the present invention also performs the operation of constant folding in this single, multi-operation pass so that the QP, upon receiving the QP Algebra, needs not perform this operation at all.
摘要翻译：本发明的SQL代理器包括使用比典型的代数器更一致和更有效的方法来将“SQL树”组合到QP代数的多种算法。更具体地说，本发明的代理者通过在单程中执行多个操作，使用减少数量的递归深度优先遍历来处理SQL树。此外，本发明的代理还在该单次多操作遍中进行恒定折叠的操作，使得在接收到QP代数时，QP根本不需要执行该操作。

摘要： Any string in any character set with an arbitrary-leveled weight-based comparison system is transformed into a bitstring in such a way that two transformed strings can be compared byte-by-byte. The resulting bit string has the minimum possible maximum length. The transformed bit strings can be inverted—meaning the original string can be recovered from the transformed string.
摘要翻译：任何具有任意级别的基于权重的比较系统的字符集中的任何字符串被转换成位串，使得可以逐字节比较两个变换的字符串。所得到的位串具有最小可能的最大长度。转换的位串可以被反转，这意味着可以从转换的字符串中恢复原始字符串。

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.

摘要翻译：数据库系统和方法允许用户以实现定义用户定义类型的结构的类的高级编程语言编写程序代码，并且可以在该类型的实例上调用方法。该类然后向数据库系统注册，该系统针对类强制执行用户定义类型的特定合同。合同包括以下要求。首先，类必须为数据库存储中的用户定义类型的持久化实例指定多种不同格式之一。第二，类必须能够返回用户定义类型的空值。第三，类必须提供一种将用户定义类型转换为另一种类型的方法。一旦满足这些要求，数据库系统就可以创建用户定义类型的实例。可以在可以使用任何其他内置类型的所有上下文中使用用户定义的类型。这包括定义表的列，将变量和参数声明为函数和存储过程，以及评估SQL查询和更新中用户定义类型的表达式。优选地，数据库系统存储关于用户定义类型的元数据，以便随后用于创建该类型的实例。

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.
