A label feature class can only be created from the feature class level. Each feature class can have only one label feature class.
The default attributes of a label feature class are as follows:
Default Attributes of the Label Feature Class |

FID |
Primary key |
FID_PARENT |
Foreign key to parent table’s FID |
GEOM |
Label geometry = insertion point. For more information, see Oracle Spatial Users Guide and Reference. |
HORIZONTAL_ALIGNMENT |
Horizontal alignment of the label. The default is Center. |
LABEL_DEF_ID |
Foreign key to TB_LABEL_DEF.ID. |
LABEL_TEXT |
Text of the label. |

This value is no longer used. Use alignment attributes instead. See also Label Properties: ORIGIN conversion |

VERTICAL_ALIGNMENT |

A label feature class always belongs to a parent feature class (relation FID_PARENT). Normally a label feature class has no additional columns and the application user will never edit it. The attributes of a label feature class are generated when a user places a label.
