Access Data in an Object (dbo_access-data_in_object.htm)
Data is held in an object within fields. Depending on the object definition, this data may be directly accessible using the -> operator.
Object -> field = expression
Object -> field
| Object | DBO variable name. |
| field | The object field name being accessed. |
| -> | The object operator. |
