Benefits of technology

The technology described by this patented allows for efficient transformation between different forms or tables from multidimensional expressions without requiring complex calculations that are time-consuming processes. This reduces processing requirements while still providing accurate results.

Problems solved by technology

This patented technology describes how complex XML expressions are converted from their original form for analysis purposes by performing certain transformations based on predefined templates or predetermined criteria. However, this approach may result in poor performance due to its complicated structure with many different types of transformation steps needed depending upon specific scenarios being analyzed.

Abstract

The invention discloses a method and a device for database query statement generation. The method for database query statement generation comprises the steps of acquiring multi-dimensional expression statements; grouping the multi-dimensional expression statements according to the type of a query operation to acquire target groups; respectively generating a plurality of preset conversion templates according to the plurality of target groups; converting the multi-dimensional expression statements to be converted into database query statements according to the target conversion templates. The problem of higher complexity during conversion from the multi-dimensional expression statements to the database query statements is solved, and the effect of reducing the complexity of conversion from the multi-dimensional expression statements to the database query statements is further achieved by generating the plurality of preset conversion templates according to the plurality of target groups and converting the multi-dimensional expression statements to be converted into database query statements according to the target conversion templates.
