How to see data selected from a database

In order to exercise SELECT, we need to know which values were selected from the database. How to show data is covered in Chapter 7, Building User Interfaces. For now, I will get you a fragment of code to display data, which is selected from your SELECT statement.

DATA: gr_alv     TYPE REF TO cl_salv_table,
      gr_columns TYPE REF TO cl_salv_columns_table.
 
 CALL METHOD cl_salv_table=>factory
   IMPORTING
     r_salv_table = gr_alv
   CHANGING
     t_table      = YOUR TABLE.
 
 gr_columns = gr_alv->get_columns( ).
 gr_columns->set_optimize( value = 'X' ).
 gr_alv->display( ).
