LOOP AT dbtab

Short Reference

Other versions: 7.31 | 7.40 | 7.54

Obsolete Syntax

LOOP AT { dbtab | *dbtab } [VERSION vers].


... VERSION vers


The statements LOOP and ENDLOOP define a loop around a statement block (not allowed in classes). For dbtab, you must specify a database table that begins with "T" and has a maximum length of five characters. For the database table 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 dbtab must be character-type.

In each loop run, the statement LOOP reads a line from the database table dbtab and assigns its content either to the table work area, or on specification of *dbtab, to the additional table work area. The lines to be read are determined by the content of the components of the table work area, which correspond with the primary key fields of the database table dbtab. Before the first loop run, the content of these components is taken as the search key, reading from the left, and the database table is searched generically for suitable entries. The search key handles blanks as if they match all values.

If a database table is specified that does not begin with "T", then the first letter is implicitly replaced by "T". The loop is not executed if the database table does not exist

System Fields

sy-subrc Meaning
12 The database table was not found.


  • This form of the LOOP-loop is not allowed in classes. It must be replaced by the statement SELECT.
  • 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.


... VERSION vers


If the addition VERSION is specified, then the database table dbtab is not read, and the table 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.


Sequential reading of rows from database table T100.

TABLES t100.

t100 = space.
t100-sprsl = 'E'.
t100-arbgb = 'BC'.
t100-msgnr = '1'.

LOOP AT t100.

The Open SQL syntax to be used instead reads:

DATA wa TYPE t100. 

       FROM t100 
       INTO wa 
       WHERE sprsl = 'E' AND 
             arbgb = 'BC' AND 
             msgnr LIKE '1%'.
