when you get a duplicate key error it says something to the effect
of "Duplicate entry 'xyz' for key x"
What I want to know is how to find out what table fields are part of key x?
'show index' is what you want, I think:
http://dev.mysql.com/doc/refman/5.0/en/show-index.html
Example:
[EMAIL PROTECTED]> create table test (c1 int, c2 int, index
i1 (c1,c2));
Query OK, 0 rows affected (0.02 sec)
[EMAIL PROTECTED]> show index from test\G
*************************** 1. row ***************************
Table: test
Non_unique: 1
Key_name: i1
Seq_in_index: 1
Column_name: c1

Cardinality: NULL
Sub_part: NULL
Packed: NULL
Null: YES
