Method to execute the sql query set in the 属性中设置的sql查询之前,
Finally, we implement that query set language encodes large numbers of possible queries, the tql expresses and calculates queries, and the algorithm from qss to tql and the one from tql to xquery 最后,实现了qss对查询要求的描述、tql语言的表示和计算、以及qss到tql的转换算法和tql到xquery查询表达式的转换算法。
In the thesis, the algorithm transforming from the query set specification to the tree query language is represented, and to construct condition tree ct by the set of condition fragments and convert instantiated rtg to result tree rt 本文给出了从查询组规范qss描述语言到树查询语言tql(treequerylanguage)的转换算法,分析了从活动片断子集到ct的构造过程,以及从rtg到rt的转换过程。
