ENDLOOP.
Addition:
Effect
The statements LOOP and ENDLOOP define a loop around a statement block, which is forbidden in classes. dbtab expects a database table or DDIC table view that starts with "T" and has a maximum length of five characters. For the database table or view dbtab, a table work area or an additional table work area must be declared using the statement TABLES. All components of the table work area that match the primary key fields of the database table or view dbtab must be character-like.
In each loop pass, the statement LOOP reads a row from the database table or view dbtab and assigns its content either to the table work area, or if *dbtab is specified, to the additional table work area. The rows to be read are determined by the content of the components of the table work area that match the primary key fields of the database table or view dbtab. Before the first loop pass, the content of these components is taken left-aligned as the search key and the database table or view is searched generically for suitable entries. The search key handles blanks as if they match all values.
If a database table or view is specified that does not start with "T", the first letter is implicitly replaced by "T". The loop is not executed if the database table or view does not exist.
System Fields
| sy-subrc | Meaning |
| 12 | The database table or view was not found. |
Notes
- This form of the LOOP-loop is not allowed in classes. It must be replaced by the SELECT statement.
-
The obsolete access statements do not support automatic
client handling. The
client identifier
of a database table must be specified explicitly. The application programs are only to work with data for the current client. In systems with
multitenancy, this is checked by the ABAP runtime environment.
Addition
... VERSION vers
Effect
If the addition VERSION is specified, the database table or view dbtab is not read, and
the table or view whose name is composed of "T" and the content of vers is read instead. vers
expects a data object with a maximum of four characters, of type c. The content of the row is
still assigned to the table work area of dbtab or *dbtab and its type is cast. If the table work area is too short, a runtime error occurs.
Example
Sequential reading of rows from database table T100.
TABLES t100.
t100 = space.
t100-sprsl = 'E'.
t100-arbgb = 'BC'.
t100-msgnr = '1'.
LOOP AT t100.
...
ENDLOOP.
