Sliding certain records to the end of a run of the same date

Question

I have three columns -

• TheDate - Obviously a date.
• TheID - A strictly increasing ID.
• TheType - A Record t

Answer 1

If TheID cannot be null then just change the TheID to null as part of the order by where TheType is a special value:

order by TheDate, 
         case TheType
           when 101 then null
           else TheID
         end nulls last
