Passing a variable to select statement

Question

Hi there,
I have a selection screen on which you can choose which table do you want to display.
I store the name of the selected table in a variable tab_name.
I want to use something like that:
data: tab_name(40).
select * from tab_name
    into gt_master.
endselect.
But it did not allowed because tab_name is not a database table.
Is it possible to pass the table name in a select statement using a variable?

Hello
Yes it is posible you can use a dynamic select...
Try this:
DATA  tabname(10).
DATA: BEGIN OF wa,
        id   TYPE scustom-id,
        name TYPE scustom-name,
      END OF wa.
tabname = 'SCUSTOM'.
SELECT id name INTO CORRESPONDING FIELDS OF wa FROM (tabname).
  WRITE: / wa-id, wa-name.
ENDSELECT.
or
CONSTANTS: flight_tab_name(30) VALUE 'SPFLI'.
DATA: from_clause TYPE STRING.
DATA: BEGIN OF wa,
        name(20) TYPE C,
        connid   TYPE spfli-connid,
      END OF wa.
CONCATENATE flight_tab_name ' AS t1'
            ' JOIN scarr AS t2 ON t1carrid = t2carrid'
   INTO from_clause.
SELECT t1connid t2carrname AS name
    FROM (from_clause)
    INTO CORRESPONDING FIELDS OF wa.
  WRITE: / wa-name, wa-connid.
ENDSELECT
Hope this helps
