child node is the sharding item sequence number, starting from zero and ending with the total number of shards minus one. The child node of the sharding item sequence number stores detailed information shardingItemParameters: The sequence numbers and parameters of the Sharding items are separated by equal sign, and multiple key‐value pairs are separated by commas. The Sharding sequence number starts from 0 divided, the redundant sharding item that cannot be divided will be added to the server with small sequence number in turn. For example: 1. If there are 3 job servers and the total sharding count is 9, each

If your database table uses an IDENTITY, AUTO_INCREMENT, or SERIAL column, or you have defined a SEQUENCE/GENERATOR, you can use the element in an statement to use or return that database-generated
