LOB Handle Structure
The structure of a special work area to support streaming and locators for LOBs in ABAP SQL. LOB handle structures have the same components as database tables or views. However, there is at least one component which is assigned to an LOB, which is not a string but a LOB handle component instead. A LOB handle structure can be defined by component using ABAP statements or in ABAP Dictionary or it can be derived by referencing a structure which contains LOBs.
