摘要： Queries targeting various data sources are processed in a query processing pipeline that parses the query into a set of operations (e.g., an expression tree or a translated SQL query) using a set of query operators, each handling a particular type of operation. The query operators are often designed in an unspecialized manner, such that each query operator handles one query operation in an atomic, generic manner (e.g., sorting generic data items for an ORDER BY clause.) More efficient queries may be devised by including specialized queries that operate in common but special cases, such as a sorting of a particular data type (e.g., a floating-point number sort) or a sequence of two or more operations that are often performed together (e.g., a WHERE test of an attribute followed by a SELECT of the same attribute.) The use of specialized operators may result in the formulation of more efficient queries.

摘要： The present invention extends to methods, systems, and computer program products for representing various programming elements with compiler-generated tasks. Embodiments of the invention enable access to the future state of a method through a handle to a single and composable task object. For example, an asynchronous method is rewritten to generate and return a handle to an instance of a builder object, which represents one or more future states of the asynchronous method. Information about operation of the asynchronous method is then passed through the handle. Accordingly, state of the asynchronous method is trackable prior to and after completing.

摘要： A static type, called “dynamic”, is introduced into a statically bound programming language. An expression or subexpression that is defined as a static type called “dynamic” in the source code of a program written in the statically bound programming language, is bound based on its runtime type instead of on its compile time type. Binding can be performed based on a mixture of compile time and runtime types that are based on the specification of types of expressions in source code. This type of binding is called hybrid binding. Operations are bound using the runtime type of constituent expressions (i.e., the runtime type of a receiver, an argument, or an operand) typed as dynamic and the compile time type of static constituents. If any constituent expression of an operation is dynamic, binding occurs at runtime instead of at compile time.

摘要： The utilization of data services (such as web services) may involve the invocation of services, which may reduce performance and overburden the server. In some scenarios, the invocation may be specified in a language that does not support batch invocation, but it may not be feasible to re-code the invocations in a language that supports batching. Instead, the service invocations may be automatically translated into a batch logic specified in a batch-capable language and sent to the service as a batch. For example, a local proxy may receive a language-integrated query having two or more service invocations, compile the query into an expression tree including the two or more invocations, and send the expression tree to the service host to achieve the batch processing of the service invocations.
摘要翻译： 数据服务（如Web服务）的使用可能涉及服务的调用，这可能会降低服务器的性能和负担。 在某些情况下，可以使用不支持批量调用的语言来指定调用，但以支持批处理的语言重新编码调用可能不可行。 相反，服务调用可以自动转换为以批处理语言指定的批处理逻辑，并作为批处理发送到服务。 例如，本地代理可以接收具有两个或多个服务调用的语言集成查询，将查询编译成包括两个或更多个调用的表达式树，并将表达式树发送到服务主机以实现批处理 服务调用。

摘要： The present invention extends to methods, systems, and computer program products for transforming source code to await execution of asynchronous operations. Embodiments of the invention simplify authoring and use of asynchronous methods, by generating statements that use well-defined awaitable objects to await completion of asynchronous operations. For example, a computer system can transform a statement that requests to await the completion of an asynchronous operation into a plurality of statements that use a predefined pattern of members of an awaitable object corresponding the asynchronous operation. The pattern can include one or more members configured to return a completion status of the asynchronous operation, one or more members configured to resume execution of the asynchronous method at a resumption point when the asynchronous operation completes, and one or more members configured to retrieve completion results. Accordingly, the plurality of statements can use these members to await execution of the asynchronous operation.
摘要翻译： 本发明扩展到用于转换源代码以等待执行异步操作的方法，系统和计算机程序产品。 本发明的实施例简化了异步方法的编写和使用，通过生成使用明确定义的等待对象等待完成异步操作的语句。 例如，计算机系统可以将请求等待完成异步操作的语句转换为使用对应于异步操作的可等待对象的成员的预定义模式的多个语句。 该模式可以包括被配置为返回异步操作的完成状态的一个或多个成员，被配置成在异步操作完成时在恢复点恢复异步方法的执行的一个或多个成员以及被配置为检索完成的一个或多个成员 结果。 因此，多个语句可以使用这些成员来等待异步操作的执行。

摘要： Data source queries may be specified in various languages, such as SQL, XQuery, and object-oriented languages, and each language may have various linguistic features that enable different types of queries. It may be advantageous to formulate mixed language queries having portions specified in a first language and portions specified in a second language, and to provide mixed language query evaluation components that can parse portions of queries of different languages. It may also be advantageous to permit the translation of single language queries into multiple languages to be parsed by such mixed language query evaluation components. Such techniques may permit queries to utilize linguistic features and processing techniques of one language that are less efficient, less direct, or simply unavailable in another language.
