Error 1062: Duplicate entry 'mydb/regimes' for key 'name'

Question

I am not an expert on databases but I'm modeling a database on mysqlworkbench 8.0.13 and when I try to run the script it breaks at this table(regimes). I can't figure out what KEY 'NAME' it is referring to. There's no key called name on this table.

I use this table's id as FK on two other tables. And both relationships are ONE-TO-MANY. But I don't think this should be a problem. Can anyone please be so kind as to point me in the right direction to solve this problem?

Answer 1

Error 1062: Duplicate entry ... is an error indicating you've tried to INSERT or UPDATE (explicitly or implicitly) a row in a table using a key that already exists and that key column is defined as being unique in the table/index. This could be a primary key or another key that has been explicitly defined as unique. However, in your case, I suspect the duplicate entry results from trying to create an index with the same name twice. (I came to that conclusion because the index definitions themselves are also stored in a table, and the error you get refers to the name of your table as a value for the duplicate key.)

That said, I don't think the CREATE TABLE statement for regimes is what is causing this error. Your error log says you successfully ran 49 statements, and 1 statement resulted in an error. In your script, look for statements that create the name key. Do you have any CREATE UNIQUE INDEX name ON regimes ... or ALTER TABLE regimes statements? That would be something to look out for.
