Our method for the first two tasks is based on a deep parser; we store the parse tree of each sentence in a relational database scheme. From the training data, we collect the dependencies connecting any two rel
we store the parse tree of each sentence in a relational database scheme. From the training data, we collect the dependencies connecting any two relevant terms of a known tuple, that is, the shortest paths linking these two constituents. We encode all such linkages in a query language ...
* A "simple" SELECT is represented in the output of gram.y by a single * SelectStmt node; so is a VALUES construct. A query containing set * operators (UNION, INTERSECT, EXCEPT) is represented by a tree of SelectStmt * nodes, in which the leaf nodes are component SELECTs and the i...
A parse tree represents an expression, not immediately evaluated. Its virtue is that the expression can be evaluated whenever and in whatever context it is needed. The two main functions dealing with parse trees are eval, which evaluates a parse tree, an

利用内部算法对sql进行解析,生成解析树(parse tree)及执行计划(execution plan)。 Step4、执行sql,返回结果(execute and return) 3. 硬解析的危害: (1) 占用资源更多,执行慢,因为不会重用已解析好的query plan。 (2) 硬解析导致library cache上的latch竞争,这会降低系统的并发性,使oracle无法充分利用系统资源。
