Hi,

in case of 'variable' selects i use &Variables. Here is stmt.statement the clob column.

Code
select ...
 ,&< name = "Statement Clob" 
     hint = "with clob?" 
     list = "    NULL           ""Statement Full""    ,N
              ,""stmt.statement ""Statement Full"" "" ,J 
            " 
     description=YES 
     DEFAULT = "N"
   > 
...

There is no shortcut for experience(d).
