Mysql updates the data without error prompts, but what is the reason for not updating it?

there is no problem for the database to insert data using Mysql, insert, but I don"t know why the update data has not been updated successfully. The mysql update statement is as follows:

UPDATE `system_member`  SET `passwd`="e968053af15baf1b6f52458bb693deff"  WHERE  `id` = 1;

ask the leaders of the community to help analyze the reason. Thank you very much!

if you look at it this way, you don't see any problem for the time being, at least there is no problem with the sentence. Well, if you say that the update has not been successful, would you first check to see if your data is exactly the same as what you are updating now? if yours is exactly the same, in this way, the impact line will not change.
