mysql - 对同一个表同时更新2条记录，但更新不同字段，会不会造成数据丢失？

Question

运营要求修改某条记录的权重，但用户参与的时候，会对另外一个字段更新，如果用户和运营的操作是同时进行的话，会不会导致前者或者后者更新丢失 ？

Answer 1

Let’s put it this way. When data is updated, a write lock is added. When another operation is to be written, it will enter waiting. until the write lock is released.

Answer 2

Updating different fields will not work, provided that each of your update statements only updates one field

Answer 3

No, make sure the where condition of update is correct
