This study proposes a model, named QUERY2TREE, to combine a graph representative learning model and large language model to augment semantic for embedded entities of the knowledge graph such that these entities
Lemma:Let L be an operator tree such that schema(L) contains attributes from base tables A1, ..., An. Let J be the set of joins in L and let A* be an arbitrary table in the schema of L. There is a map f: J -> schema(L) such that (1) the range of f is all of schema...
优化器的主要工作就是将 SQL parser 之后的语法树,经过一系列的转换,变成执行计划,也就是 Operator Tree。在这个变换的过程中,使用 logical operator tree (query trees) 来表示中间的数据结构,Figure2 就是 query tree。 Starburst 使用了 QGM(Query Graph Model) 来进行表示 SPJ queries。并介绍了其存的在问题...

An XML document is represented as a tree of nodes, in which a node may be a document, element, attribute, text, name-space, processing instruction, and comment. An XQuery query for XML documents consists of two parts: a prolog and a body. The query prolog is an optional section and ...
You cannot return the entire category tree if the total number of nodes in the request exceeds the value specified in thequeryDepthattribute defined in the GraphQLdi.xmlfile. By default, this value is 20.Query securityfurther describes query depths. ...
