Michael,
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:
select column_name
|| ' '
|| decode( data_type
, 'NUMBER', decode( data_precision
, null, 'NUMBER'
, 'NUMBER('
|| data_precision
|| ','
|| data_scale
|| ')'
)
, decode ( data_type
, 'DATE', data_type
, data_type
|| '('
|| data_length
|| ')'
)
) value
from dba_tab_columns
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.
Mark.

It may not help you with the columns, but just a warning- I use CDC a
lot and found out if you have any unused columns in a table, it will
cause you a mighty headache in failures. CDC does not like unused
columns! :(
Not that most people have this problem, but as a new DBA starting out
here, I sure was unhappy to see them:
select owner, table_name, count from dba_unused_col_tabs;

Hello
I am going through the documentations on how to set up CDC with
Asynchronous HotLog.
Executing DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE requires listing all
column names and data types.
Is there an efficient way of getting all the columns in the table?
BEGIN
DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE(
owner => 'cdcpub',
change_table_name => 'products_ct',
change_set_name => 'CHICAGO_DAILY',
source_schema => 'SH',
source_table => 'PRODUCTS',
column_type_list => 'PROD_ID NUMBER(6), PROD_NAME VARCHAR2(50),
PROD_LIST_PRICE NUMBER(8,2)',
capture_values => 'both',
rs_id => 'y',
row_id => 'n',
user_id => 'n',
timestamp => 'n',
object_id => 'n',
source_colmap => 'n',
target_colmap => 'y',
options_string => 'TABLESPACE TS_CHICAGO_DAILY');
END;
/
TIA
