Question

I know SQL, but am not heavy in SQL. So, here is a question that I would want to know if it is possible and if so how.. (Group By?)

We have a table

Data   Date
1      JUN-1-2001
2      JUN-1-2001
3      JUN-2-2001
4      JUN-2-2001
5      JUN-3-2001

I would like to have the result set sorted by date with a “pre header” of the date, something like…

Target is SQLLite 3

Data    Date
0       JUN-1-2001
1       JUN-1-2001
2       JUN-1-2001
0       JUN-2-2001
3       JUN-2-2001
4       JUN-2-2001
0       JUN-3-2001
5       JUN-3-2001

Anyway, would appreciate the help on this one. There is a reason for my madness.

Answer 1

Try:

select data, date from mytable union all
select distinct 0 as data, date from mytable
order by 1, 2
