Abstract

The invention discloses a data updating method and device, electronic equipment and a computer readable storage medium. The data updating method comprises: reading object data, wherein operation processing is conducted on the object data by a plurality of transaction objects; then detecting whether updated data exist in the object data or not, wherein the updated data refer to data changed on the basis of a current data version, and the current data version corresponds to a data current value; if the updated data exist in the object data, combining all the updated data, and finally loading the combined updated data into the current data value. The technical problem that the success rate is low when data updating is carried out under concurrent transactions in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of data updating, in particular to a data updating method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] "Lock" is used for "concurrency control". Its purpose is to prevent unreasonable phenomena when different users operate on the same data. At present, there are mainly pessimistic locks and optimistic locks. Among them, pessimistic locks The characteristics are exclusive and exclusive. Typical pessimistic locks are mainly shared locks or exclusive locks; optimistic locks assume that data will not cause conflicts under normal circumstances, so when the data is submitted for update, it will detect whether the data conflicts. If a conflict is found, the wrong information will be returned to the user, allowing the user to decide what to do, which essentially solves the problem of reading data under concurrent transactions, but after the data is r...
