Hi Sasikala,
Just for your understanding am giving a sample code snippet which you can use to read the contents of your Table UI element & save the data on to your database. Suppose you have a button up on pressing which you want to read the data from your screens table & save on to the database then you can proceed as shown below:
1) Obtain the reference of your context node.
2) Fetch all the data present in your table into an internal table using methods of if_wd_context_node
3) Use your normal ABAP logic to update the database table with the data from your internal table
In my example I have a node by name SFLIGHT_NODE and under this I have the desired attributes from SFLIGHT. Am displaying these in an editable table & the user would press up on a push button after making the necessary changes to the tables data. I would then need to obtain the tables information & save on to the database.
data: node_sflight           type ref to if_wd_context_node,
        elem_sflight           type ref to if_wd_context_element,
        lt_elements            type WDR_CONTEXT_ELEMENT_SET,
       stru_sflight           type if_main=>element_sflight_node,
       it_flights             type if_main=>elements_sflight_node.
"   navigate from <CONTEXT> to <SFLIGHT_NODE> via lead selection
    node_sflight_node = wd_context->get_child_node( name = 'SFLIGHT_NODE'  ).
   lt_elements = node_sflight->get_elements( ).
"   Get all the rows from the table for saving on to the database
    loop at lt_elements into elem_sflight.
      elem_sflight->get_static_attributes( importing static_attributes = stru_sflight ).
      append stru_sflight to it_flights.
    endloop.
" Finally save the entries on to the database
    modify ZSFLIGHT99 from table it_flights.
    if sy-subrc eq 0.
endif.
However a word of caution here.... SAP doesn't ever recommend directly modifying the database through an SQL query. You would preferably make use of a BAPI for the same. Try go through Thomas Jung's comments in [here|modify the data base table which is comming dynamiclly;.
