MySQL Select statement trouble

Question

Look at the pic. How it even possible? How to avoid this?

I've no records with StartDate>='2013123-12-1'

Answer 1

Maximum year supported by MySQL is 9999.

MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.
