unable to set a column varchar(2048) in an innodb table (1 reply)

Hi,
guys need some help here.

This is a very large innodb table i have that has over 250 columns.
when i try to alter one of the columns to varchar (1024), get an error as the following..

ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs

* I could set varchar(1792) though.

I dnt understand this completely. pls help.
Also it's not that i cannot create any new columns after this. I can create several varchar(1024) columns..

Thanks.
