摘要： The present invention is directed to a method and mechanism for calling on external procedure in a database system in which the external procedure contains embedded database query language statements. According to an aspect of the invention, the external procedure executes using the same database connection and transaction as the original calling entity for that external procedure.

摘要： A multithreaded client application initiates multiple database operations associated with at least one transaction. The client application allocates and stores a separate runtime context for each of the database transactions. These transaction runtime contexts are also distinct from the state information, or runtime context, of the thread initiating a particular operation of the transaction. As a result, operations started by a thread that terminates may be continued, or resumed, by a subsequent thread without having to reperform previously executed operations. The duration of the transactions' runtime context is thus decoupled from the duration of the thread's runtime context. Special syntax and routines are provided for explicitly allocating a runtime context and deallocating a runtime context.

摘要： A method and apparatus for passing runtime contexts between threads in a multithreading application is provided. A precompiler is provided which allows programmers to declare and use runtime contexts in the same manner as other conventional variable types are declared and used. Special syntax and routines are provided for explicitly allocating a runtime context and deallocating a runtime context, thus decoupling the duration of a runtime context from the duration of the thread that initiated the operations whose states are stored in the runtime context. Consequently, operations started by a thread that terminates may be continued by a subsequent thread without having to re-perform previously executed operations. Precompiler directives are provided to explicitly state which runtime contexts will be used for certain operations. A single thread can therefore use one or more runtime contexts.

摘要翻译： 提供了一种用于在多线程应用程序中的线程之间传递运行时上下文的方法和装置。 提供了一个预编译器，允许程序员以与其他常规变量类型声明和使用相同的方式来声明和使用运行时上下文。 提供了特殊语法和例程，用于明确分配运行时上下文并释放运行时上下文，从而将运行时上下文的持续时间与发起其状态存储在运行时上下文中的操作的线程的持续时间相分离。 因此，可以由后续线程继续由终止的线程开始的操作，而不必重新执行先前执行的操作。 提供预编译器指令以明确地说明哪些运行时上下文将用于某些操作。 因此，单个线程可以使用一个或多个运行时上下文。

摘要： A computer-implemented method of streaming a plurality of messages from a source queue to at least one destination queue over a computer network. The method may include steps of generating a remote procedure call, the remote procedure being configured to encapsulate at least header data, message data for each of the plurality of messages and an end of batch token, the header data being common to each of the plurality of messages and including an identification of the at least one destination queue, the end of batch token signaling that no further message data follows; sending the generated remote procedure call over the computer network to the destination queue identified in the header data, and dequeueing at least the message data for each of the plurality of messages from the source queue and streaming the dequeued messages over the network, and successively enqueueing each streamed message data into the at least one destination queue identified by the header data until the end of batch token is received.
