Open SQL supports access to LOBs using streams and locators. For a similar read access to these streams and locators, there are the interfaces
which both include the superordinate interface
which then also includes the <>IF_ABAP_CLOSE_RESOURCE> interface.
The connection to streams and locators is as follows:
The instances of the system classes which implement the IF_ABAP_DB_LOB_HANDLE interface are called LOB handles.
Note
The LOB interfaces shown here can only be used for read accesses. Reference variables for LOB handles which are specified as read targets of the INTO clause in the SELECT statement can be typed statically using these interfaces. The class which is used to create the object must then be specified using the special addition CREATING in the SELECT statement. For write accesses with the statements INSERT, UPDATE, or MODIFY, the reference variables which are used as a source must be typed using the classes for write streams or locators.
