Cannot drop a column in Sybase table

I tried to drop a column in a Sybase table but I am getting this exception:

开发者_高级运维

Can't allocate space for object 'TABLE1' in database 'SAMPLE' because 'default' segment is full/has no free extents. If you ran out of space in syslogs, dump the transaction log. Otherwise, use ALTER DATABASE to increase the size of the segment.

I already tried ALTER DATABASE but to no avail. Please help.

Have you tried this?
