When I click the "edit" pencil on my PRIMARY key on a simple table, a message in a red box says
("PRIMARY" must be the name of and only of a primary key!)
Well, it is. The PRIMARY index is defined on a column called "time_stamp", which is, surprisingly, a timestamp. The index name and index type are both "PRIMARY". Nothing fancy about it. The time_stamp field is defined as CURRENT_TIMESTAMP, not NULL.
Everything seems to work OK. So what is this error message all about? I have never attempted to create records with the same timestamp.
Using MySQL 5.5, Safari on Mac OS 10.7.3.
There is no error. It's just that one of the PMA programmers used a message of type "error".
This has been fixed in the upcoming version 3.5.0 and the message is now of type "notice".
