Duplicated Check Constraints

[aarroyob]

Thanks for your quickly reply Pando, but it doesn't work:

SQL> select table_name
2 from user_constraints where
3 search_condition='"ANO" IS NOT NULL';
search_condition='"ANO" IS NOT NULL'
*
ERROR en lÃ*nea 3:
ORA-00997: uso no válido del tipo de datos LONG
(invalid use of datatype LONG)

(I think you understand spanish no? :-) )

Regards

Angel
