SELECT command with variables

[Former Member]

Hi,

I have a number of table-variables and field-variables coming from a dialog. I can easily concatenate those into constructs like [table]~[field].

Following, I have a SELECT statement that simply fetches all those fields from n different DB tables which are for that purpose connected, currently using JOINs.

What I need to find now is a way to use those construct-variables in the SELECT statement, as simple as that. The idea is that I will, going forward, concatenate those into a field_list and put that into the command since that way I will be independent of how many fields there might be.

Can anybody give me a hint on how to do that? I haven't yet found out.

Thanks a lot!

Best regards,

Hi - Below section of code could be helpful. Please check.

DATA: lv_sel_list TYPE TABLE OF edpline," Dynamic sel list
         lv_xref TYPE REF TO cx_dynamic_check,
         lv_message_txt TYPE string,
         lv_whereclause TYPE string.

   CONSTANTS : lc_x(5) VALUE  ' ''X'' '.

*For each entry in zbc_dbtrack select count and groupby fieldname
   LOOP AT i_dbtrack INTO w_dbtrack.

     APPEND 'count(*) as count' TO lv_sel_list.
     APPEND w_dbtrack-zgbfield  TO lv_sel_list.
     IF w_dbtrack-zgbfield IS NOT INITIAL.
       TRY.

*Dynamic Count and groupby field name
           SELECT (lv_sel_list)
           FROM (w_dbtrack-ztable)
           INTO TABLE i_fieldcount
           GROUP BY (w_dbtrack-zgbfield).

*Get count of flagged for deletion data
           IF w_dbtrack-zdelfield IS NOT INITIAL.

*Dynamic where clause
             CONCATENATE w_dbtrack-zdelfield '=' lc_x
             INTO lv_whereclause
             SEPARATED BY space.

             SELECT (lv_sel_list)
              FROM (w_dbtrack-ztable)
              INTO TABLE i_delfieldcount
              WHERE (lv_whereclause)
              GROUP BY (w_dbtrack-zgbfield).

           ENDIF.

*Catch dynamic sql errors
         CATCH cx_sy_dynamic_osql_error
      cx_sy_create_data_error INTO lv_xref.

           lv_message_txt = lv_xref->get_text( ).

           MESSAGE lv_message_txt TYPE 'E'.


       ENDTRY.
