Abstract

The invention discloses a data synchronization method, device, electronic equipment and storage medium. The method includes: in the case of failure to write the target data obtained from the source data table into the target data table, determine the reason for the data writing failure; if the reason is that the data length of the data item contained in the target data is greater than the the field length of the target data table, modify the field length of the target data table to be no less than the data length of the data item; rewrite the target data that failed to be written into the target data table. Therefore, during the data synchronization process, if the data synchronization fails due to the excessive length of one or more target data items, the field length of the target data table will be automatically modified, and the target data that failed to be written will be rewritten into the target data table until Write all target data into the target data table to complete the whole process of data synchronization.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data synchronization method, device, electronic equipment, and storage medium. Background technique [0002] In the existing technology, whether it is data synchronization of heterogeneous databases or data synchronization of homogeneous databases, if the data synchronization fails due to too long data, the subsequent data synchronization is generally completed by manually locating the problem and manually modifying the field length of the table structure . In this way, when the number of fields in the data table is large, it is not easy to determine which field has too long data, the efficiency is low, and manual modification of the table structure is prone to errors. Contents of the invention [0003] The invention provides a data synchronization method, device, electronic equipment, and storage medium to solve the defects of low efficiency and error-prone defects ...
