Question is, how far do you go?
Just char, varchar, nchar, nvarchar, binary, varbinary?
Also decimal and numeric (default is numeric(18,0))?
Also time (default is time(7)), datetime2 (default is datetime2(7)) and datetimeoffset (default is datetimeoffset(7))?
The new datetime and time default to their highest precision. Numeric and decimal default to something in the middle. The character and binary types default to their minimum when declared.
