Database data query method and device based on state dictionary, electronic equipment and storage medium

The invention discloses a database data query method and device based on a state dictionary, electronic equipment and a storage medium. The method is characterized by comprising the following steps: receiving a data query instruction for a target database, and determining target query data corresponding to the data query instruction; performing Hash calculation on the target query data according to a Hash function group stored in a state dictionary, and determining a query Hash value of the target query data; and if a target hash value which is the same as the query hash value exists in the hash bit array stored in the state dictionary, sending the data query instruction to a target database for data query. The pre-query of the data stored in the database is realized, the data which does not exist in the database can be filtered through the state dictionary, the number of times of querying the database by invalid data is reduced, and the query efficiency is improved. 本发明公开了一种基于状态字典的数据库数据查询方法、装置、电子设备和存储介质。其特征包
