What are the privileges required to use triggers?

We must have SUPER privileges to create or destroy triggers with the help of a CREATE or DROP statement. Other than that if the triggered statements use OLD or NEW then there are some additional privileges as follows which we require −

  • To assign the value of a column with SET NEW.column_name = value then we must have the UPDATE privilege for the column.
  • To use NEW.column_name in an expression to refer to the new value of a column, we must have the SELECT privilege for the column.
