Choose the drop-down control, define your own events: ue_dropdown event_id: pbm_cbndropdown
Datastore lds_object

Lds_object. Dataobject='d_select_data'
Lds_object. Settransobject (sqlca)
Lds_object. Retrieve ()
Ll_rowcount=lds_object. Rowcount ()
If ll_rowcount & lt; 1 then return
For ll_row=1 to ll_rowcount
ls_add_data=https://bbs.csdn.net/topics/lds_object.getitemstring (ll_row, 'col_name)
If isnull (ls_add_data) or trim (ls_add_data)='then continue;

Also can use the cursor:
Declare c_data cursor for
