   # == Conditions
   #
   # Conditions can either be specified as a string, array, or hash representing the WHERE-part of an SQL statement.
-  # The array form is to be used when the condition input is tainted and requires sanitization. The string form can
-  # be used for statements that don't involve tainted data. The hash form works much like the array form, except
-  # only equality and range is possible. Examples:
