You can write a bit of PL/SQL around the dbms_cdc_publish call and query dba_tab_columns to generate the list of columns with the data types.
E.g. something like:
|| ' '
|| decode( data_type
, 'NUMBER', decode( data_precision , null, 'NUMBER' , 'NUMBER('
) , decode ( data_type , 'DATE', data_type , data_type || '(' || data_length || ')' ) ) value
where table_name = <your table>
and owner = <owner> ;
Extend that a little and you generate all statements for a set of tables by just running a simple script.
