(OP)
hi, im not an sql guru and i hope someone can help ... this is my problem: I need to get the info from the original table to the destination table ... the question is how? (im working with ingres so please only standard sql)
A bit more info: In the original table: Each row contains a problem which is logged on a certain date and has a status. Now i want the dates grouped, and for each status a count on a certain date (see destination table)

CODE

original table:
log_date     |  status
14/feb/06    CLOSED
14/feb/06    OPEN
14/feb/06    WAITING
16/feb/06    WAITING
16/feb/06    WAITING
16/feb/06    CLOSED
16/feb/06    WAITING
16/feb/06    WAITING
16/feb/06    UNSOLVED
16/feb/06    UNSOLVED
17/feb/06    CLOSED
19/feb/06    WAITING
19/feb/06    WAITING
19/feb/06    CLOSED
19/feb/06    WAITING
19/feb/06    UNSOLVED

20/feb/06    UNSOLVED
20/feb/06    WAITING
21/feb/06    CLOSED
21/feb/06    OPEN

14/feb/06      1       1         0           1
16/feb/06      0       1         2           4
17/feb/06      0       1         0           0
19/feb/06      0       1         1           3
20/feb/06      0       0         2           1
21/feb/06      2       1         0           0


I realy hope someone can give me a good query to solve this problem ... big thanks in advance!!

RE: joins and counts

select distinct t.name,
(select count(cod) from tabela3 t3 where t3.cod='OPEN'     and t3.name=t.name) as "OPEN",
(select count(cod) from tabela3 t3 where t3.cod='CLOSED'   and t3.name=t.name) as "CLOSED",
(select count(cod) from tabela3 t3 where t3.cod='UNSOLVED' and t3.name=t.name) as "UNSOLVED",
(select count(cod) from tabela3 t3 where t3.cod='WAITING'  and t3.name=t.name) as "WAITING"
from tabela3 t order by t.name

Hope that help.
