Data query method and device, storage medium and electronic device

The invention provides a data query method and device, a storage medium and an electronic device, and the method comprises the steps: obtaining the metadata information of a to-be-queried target table, wherein the target table comprises to-be-queried data; analyzing the metadata information by using a first model, and determining a preprocessing mode of the to-be-queried data, wherein the first model is obtained by training multiple groups of data, and each group of data in the multiple groups of data comprises metadata information and the preprocessing mode corresponding to the to-be-querieddata; and processing the to-be-queried data based on the preprocessing mode so as to query the processed to-be-queried data in the Hive data warehouse. By adopting the technical scheme, the problems that in related technologies, in the process of performing data query through the Hive data warehouse, a large amount of human participation is needed to determine the processing mode of the data, theprocess is complex process
