Trunc(date) group by query

Question

Hi.
I have the following queries:
1) select trunc(fechaalta), count(*) solicitudes from solicitud group by trunc(fechaalta)
trunc(fechaalta) solicitudes
30/01/12 14
29/01/12 28
28/01/12 205
2) select trunc(fechaalta), count(*) ots from ot group by trunc(fechaalta);
trunc(fechaalta) ots
30/01/12 33
29/01/12 39
28/01/12 193
I need a table merging both queries. It would be like this:
trunc(fechaalta) solicitudes ots
30/01/12 14 33
29/01/12 28 39
28/01/12 205 193
How can I do it?.
Thanks.

Hi,

Does "with as" command work in oracle 10g?You mean "with *subquery_name* as", right? You need to give a name to each result set, right before the AS keyword. (It looks like Solomon forgot to name the 2nd subquery, and the 2nd AS keyword.)
Try this:
WITH     sulicitud_summary     AS
     SELECT       TRUNC (fechaalta)     AS dt
     ,       COUNT (*)          AS solicitudes
     FROM       solicitud
--     WHERE       ...          -- If you need any filtering, put it here
     GROUP BY  TRUNC (fechaalta)
,     ot_group_summary     AS
     SELECT       TRUNC (fechaalta)     AS dt
     ,       COUNT (*)          AS ots
     FROM       ot_group
--     WHERE       ...          -- If you need any filtering, put it here
     GROUP BY  TRUNC (fechaalta)
SELECT       NVL (s.dt,         o.dt)     AS dt
,       NVL (s.solicitues, 0)          AS solicitudes
,       NVL (o.ots,          0)          AS ots
FROM                 solicitud_summary  s
FULL OUTER JOIN      ot_group_summary   o  ON   s.dt  = o.dt
;Yes, it works in Oracle 9.1 and higher.
Solikcitud_summary and ot_summary are defined in the WITH clause. Once they are defined, you can use the result sets from those sub-queries, as if they were tables, anywhere in the query, including in other sub-queries.
For more, look up "With query_name clause of SELECT" in the SQL language manual:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_10002.htm#sthref9758
I may have made some typos, too. Unless you post CREATE TABLE and INSERT statements to re-create your tables, I can't actually test it.
I get "invalid table name" error. It is the first time using this command. Maybe I am missing something.Your message is missing something: your code. Post exactly what you're running. Even if you just copied and pasted it from this site, there may have been an editing error.
