Setting a column's datatype to autonumber

I have noticed that in Access RDBMS you are able to set the data-type of a column to autonumber which then automatically assigns a unique identifying number to each row. Is there an equivalent SQL command for a database such as mySQL?

Yes, it's the identity property with seed and increment values.

Here's the sql:

create table tablename
 (fieldname int identity (1, 10))

1 is the seed value and 10 is the increment value.

If you want other UniqueIdentifier as datatype (that 128 byte long GUID), you may assign the Default value of the column to NEWID()

create table tablename
 (fieldname uniqueidentifier DEFAULT NEWID())
