MySQL disallows the creation of the table in the first place, and displays the following error:

Error Code: 1118. Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
