- Add `as <int_type>` to sequence creation options - int_type can be signed or unsigned integer types, including tinyint, smallint, mediumint, int and bigint - Limitation: when alter sequence as <new_int_type>, cannot have any other alter options in the same statement - Limitation: increment remains signed longlong, and the hidden constraint (cache_size x abs(increment) < longlong_max) stays for unsigned types. This means for bigint unsigned, neither abs(increment) nor (cache_size x abs(increment)) can be between longlong_max and ulonglong_max - Truncating maxvalue and minvalue from user input to the nearest max or min value of the type, plus or minus 1. When the truncation happens, a warning is emitted - Information schema table for sequences
