Hi all,
I have three tables like this:
table1 with column table1_ID
table2 with columns table1_ID, date ..etc
table3 with columns table1_ID, date ..etc
I would like to create one query to retrieve the rowcount ( count(*) ) from
both table2 and table3
WHERE date BETWEEN fromdate1 AND todate1

Through whatever mechanism you are using to issue the query.

Oops. I forgot that part in my reply. So my where clause is

Håkan,
You can add as many date ranges as you need:
Select t1.id,
sum(case when t2.date between d1 and d2 then 1 else 0
end) as sum1,
sum(case when t2.date between d3 and d4 t
Adam,
I just realised that issuing the SQL on one table produces the correct count.
SELECT sum(case when table2.date between '2007-07-13' and '2007-07-13' then 1
else 0
end) as sumx FROM table2 WHERE id = n;
This is working alright.
So the problem should lie in the last part:
