摘要: The described implementations relate to updating views in a database system. One implementation can identify an active view that retrieves records from a database and determine one or more physical tables in the database that are referenced by the active view. The implementation can track one or more columns in the physical tables that are used by the active view and identify a change to the physical tables in a transaction log of the database. If the change does not affect the one or more columns, the change can be treated as an ignorable change for the active view.

摘要: The present invention discloses an improved system and method for specifying and compiling computer programs. Type aliases are introduced whose binding is inferred by a type inference component during compilation. Once declared, type aliases can be utilized just like regular types thereby providing added efficiency in coding, among other things. Additionally, a mechanism for specifying the introduction of a new variable whose type is to be inferred is disclosed. This mechanism clears up an ambiguity during type inference concerning whether to infer a new variable type or utilize a variable in scope. Further yet, an efficient type inference system and method is disclosed to effectively deal with overloading among other things.

摘要: The subject invention relates to systems and methods that provide null capabilities within the context of programming languages. In one aspect, a system is provided that facilitates null-support in various programming languages. The system includes one or more types associated with at least one programming language. A type modifier is provided to signal that the type is nullable. The type modifier enables a multi-element structure to be automatically created in association with the type wherein, the multi-element structure includes the type and a Boolean element indicating whether or not the variable is null.
