title: How to build dynamic SQL with using
body: <p>I am trying to make dynamic <code>sql</code> like this  <code>'select col1,col2 from '|| my_table ||'</code> it works fine but I want to write like this <code>sql_stmt:='select col1,col2 from :myTable';  execute immediate sql_stmt using  my_table;</code> but I have error I have same error when I want to do something like this  tooo <code>v_filter := my_proc();   sql_stmt:='select col1,col2 from my_table where :filter' execute immediate sql_stmt using v_filter;</code> is it impossible to build dynamic <code>sql</code> like this  with <code>using</code> ? If it is impossible what is another way to avoid <code>sql injections</code>  ? </p>
