BIGINT UNSIGNED value is out of range

Question

I am getting the error

BIGINT UNSIGNED value is out of range in \'(1301980250 - mydb.news_articles.date)\'

Answer 1

The problem was caused by unsigned integer overflow as suggested by wallyk. It can be solved by

1. using SELECT *, ((1 / log((date - 1301980250) * -1)) * 175) as weight FROM news_articles ORDER BY weight; (This one worked for me) `
2. Changing sql_mode parameter in my.cnf to NO_UNSIGNED_SUBTRACTION (haven't checked this)
