Error in magento when I try to delete a product

Question

When I try to delete a product in Magento I get the next error and I don't know where is the problem.

SQLSTATE[22003]: Numeric value out of range: 1690 BIGINT UNSIGNED value is out of range

Answer 1

Please try this:

DELETE FROM sales_flat_quote WHERE updated_at < DATE_SUB(Now(),INTERVAL 30 DAY);

It works for me.
