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.
