Translated question: can I create a boolean column that will only accept TRUE or FALSE? You cannot: MySQL does not have such feature (neither booleans nor check constraints). You can create an UNSIGNED TINYINT column and use 0 as false, 1 as true, but MySQL won't prevent you from inserting 2. (No se puede ya que MySQL no tiene ni campos booleanos ni check constraints). |
