Re: AUTO_INCREMENT

Under "Setting Explicit Values" it is stated that "It is possible to specify a value for an AUTO_INCREMENT column. The value must not exist in the key.", but it seems not true if the AI column key is not unique, which is stated as a possibility under "Description" setting, "It must defined as a key (not necessarily the PRIMARY KEY or UNIQUE key).".

When testing that option, the above is confirmed (select version(): 10.3.16-1-MariaDB-enterprise-log) - am able to create records with explicitly specified duplicate values for the AI column which is not part of a unique key.
