APPEND - result

Quick Reference

Other versions: 7.31 | 7.40 | 7.54

Syntax


... { ASSIGNING <fs> [CASTING]} 
  | { REFERENCE INTO dref }.

Effect

These additions can only be used when appending single rows. If the append was successful, the addition ASSIGNING is used to assign the appended row to a field symbol <fs>; the addition REFERENCE INTO is used to set a reference to the appended row in a reference variable.

The syntax and meaning are the same as when specifying the output behavior in the statement READ TABLE and the same restrictions apply regarding the modification of key fields for primary and secondary table keys. In particular, inline declarations using the declaration operators DATA and FIELD-SYMBOL are possible.


Example

See the addition INITIAL LINE.


Example

After the DO loops, the data references in stab point to the random numbers up to 50 and those in ltab point to the random numbers larger than 50 that were appended to itab.

DATA: 
  itab TYPE TABLE OF i WITH EMPTY KEY, 
  stab TYPE TABLE OF REF TO i WITH EMPTY KEY, 
  ltab TYPE TABLE OF REF TO i WITH EMPTY KEY. 

DATA(rnd) = cl_abap_random_int=>create( seed = + sy-uzeit 
                                       min  = 1 
                                       max  = 100 ). 

DO 100 TIMES. 
  APPEND rnd->get_next( ) TO itab REFERENCE INTO DATA(dref). 
  IF dref->* <= 50. 
    APPEND dref TO stab. 
  ELSE. 
    APPEND dref TO ltab. 
  ENDIF. 
ENDDO.
