Instance Method Details

#arguments ⇒ Object

The list of arguments at the next level (when the argument is of a record or table type).

This method returns an array containing type information when the type is a user-defined type and the Oracle server version is 12c or earlier. Otherwise, it returns an empty array.

#level ⇒ Object

The nest level.

Oracle manual says that it always returns zero. However it returns the depth of ArgBase#arguments calls when #arguments returns a non-empty array.

#link ⇒ Object

For :named_type or :ref, returns a string with the database link name of the database on which the type exists. This can happen only in the case of package local types, when the package is remote.

#precision ⇒ Object

The precision of numeric arguments. 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.

# File 'lib/oci8/metadata.rb', line 1590

def type_metadata
  __type_metadata(OCI8::Metadata::Type)
end

#type_name ⇒ Object

Returns a string which is the type name, or the package name in the case of package local types. 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.
