Re: Change Data Capture 10gR2

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
