I am running MySQL Workbench 6.3.8 b1228 CE (64-bit) in \"safe update mode\". I am trying to run a query with a \"WHERE\" statement, but it still returns \"Erro
As Arnolio mentions in a comment,
The important part of the error is : "...without a WHERE that uses a KEY column". So i have to ask is the email column a key column?
I wasn't focused on the KEY portion, and my email column wasn't a KEY, which caused the error. Thanks, Arnolio!
