#precision ⇒ Object
The precision of numeric type attributes. If the precision is nonzero and scale is -127, then it is a FLOAT, else it is a NUMBER(precision, scale). For the case when precision is 0, NUMBER(precision, scale) can be represented simply as NUMBER.

#scale ⇒ Object
The scale of numeric type attributes. If the precision is nonzero and scale is -127, then it is a FLOAT, else it is a NUMBER(precision, scale). For the case when precision is 0, NUMBER(precision, scale) can be represented simply as NUMBER.

#type_name ⇒ Object
A string which is the type name. The returned value will contain the type name if the datatype is :named_type
or :ref
. If the datatype is :named_type
, the name of the named datatype’s type is returned. If the datatype is :ref
, the type name of the named datatype pointed to by the REF is returned.
