Exclude unoccupied columns

Question

I would like to be able to issue a select statement in SQL*plus or use an Oracle view to return data from occupied columns only without having to specify every column name in the table.
Is there a way of doing this simply?

Answer 1

it is possible through dynamic sql.you can pass not null column as a patrameter.
look like:
=======
create or replace procedure selecttable1(p_table_name in varchar2,p_col1 in varchar2,p_col2 in varchar2,p_col3 in varchar2,p_whr in number) is
v_stmt varchar2(2000);
v_stmt1 varchar2(2000);
begin
v_stmt:='select '||p_col1||p_col2||'from '||p_table_name||'where '||p_col3||'='||p_whr;
execute immediate v_stmt into v_stmt1 ;
dbms_output.put_line(v_stmt1);
end selecttable1;
