I have created a configurable product in my website and when i try to add an upsell product with this product, i get the below error

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '3-1949' for key 'UNQ_product_link_attribute_id_link_id'

I googled out this error and found the below suggestion,

“Try to clear the product_link_* tables in the databese, seem they contain invalid data.“

I am not sure about this suggestion. Could any one suggest me the fix for this or any reference link to solve this issue would be helpful.

Thanks.

    Try to clear the product_link_* tables in the databese, seem they contain invalid data.

    Yes, this helped me… I selectively removed the values as suggested by clockworkgeek.
