I get the following error: 

ERROR 1062 (23000) at line 1901: Duplicate entry '3-3820-50-0' for key
 'UNQ_CAT_CTGR_ENTT_DTIME_ENTT_TYPE_ID_ENTT_ID_ATTR_ID_STORE_ID'

How can I find out which table and columns this is referring to?

What version of MySQL? Are you using innodb? – Phil Oct 5 '12 at 12:02

This should do it:

select table_schema, table_name, column_name
from information_schema.key_column_usage
where constraint_name = 'UNQ_CAT_CTGR_ENTT_DTIME_ENTT_TYPE_ID_ENTT_ID_ATTR_ID_STORE_ID'
order by ordinal_position

Yes it would, +1 !!! Hope you don't mind but I added table_schema so that the database of the table is known as well. – RolandoMySQLDBA Oct 5 '12 at 17:03
@RolandoMySQLDBA: good point. Thanks. – a_horse_with_no_name Oct 5 '12 at 17:12
