i have the following query
select DAY,reqport,count(message) as numberofsms,Year(datetimein) as years, Month(datetimein) as months, Day(datetimein) as days
   FROM [radiomix].[dbo].[chat]
  group by DAY,reqport,Year(datetimein), Month(datetimein), Day(datetimein)
  order by Year(datetimein) desc, Month(datetimein) desc, Day(datetimein) desc 
 

Open in new window



DAY      reqport      numberofsms      years      months      days
TH      630590      26                     2012              12           27

and the another selection is :

  select reqport
  FROM [radiomix].[dbo].[chat]
  group by reqport

Open in new window


the result
reqport
84448
630590
730165
732265
732222


i want to make a result to get this result :

This query needs an inner join not a union; do you have a common column between the tables?

excuse me  the two result from the same table [radiomix].[dbo].[chat]

but the problem in some day,month,year i don';t have records of some  reqport

Sorry, I didn't notice it was the same table.  Are you looking to remove the rows from the query result that have no value for reqport?

WHERE reqport is not NULL

It looks like you need to generate a list of unique reqport, a list of all year-month-day combinations you want to report on, and then cross join the two. The result can then be used as the left-most table in a LEFT OUTER JOIN to your table of data. This will yield zeros for the missing data.

Try like this:
SELECT d.DAY
     , r.reqport
     , COUNT(c.message) AS numberofsms
     , YEAR(d.datetimein) AS years
     , MONTH(d.datetimein) AS months
     , DAY(d.datetimein) AS days
FROM ( /* Distinct reqport values. */
    SELECT reqport
    FROM [radiomix].[dbo].[chat]
    GROUP BY reqport
) r
CROSS JOIN ( /* Distinct dates. */
    SELECT datetimein, DAY
    FROM [radiomix].[dbo].[chat]
    /* Filter to desired date range. */
    WHERE datetimein >= '2012'
    AND datetimein < '2013'
    GROUP BY datetimein, DAY
) d
LEFT JOIN [radiomix].[dbo].[chat] c
  ON c.reqport = r.reqport AND c.datetimein = d.datetimein
GROUP BY d.DAY
       , r.reqport
       , YEAR(d.datetimein)
       , MONTH(d.datetimein)
       , DAY(d.datetimein)
ORDER BY years DESC, months DESC, days DESC
;

If you require reqport or datetimein values not present in the original table, then you will need to generate the unique lists elsewhere. The assumption with above example is that each of the dates or reqport values have at least one record.

your code is powerful thank you a lot  mwvisa1 :)
please when i check your query i got some reqport with some day not included and with some month not included ?

That would mean that the day or month is not in the data at all; therefore, you will have to build up the dates via a dates (or numbers) table or through a common table expression. Plus I just realized that you probably have timestamps in the original data why you are using GROUP BY DAY(datetimein). Therefore, you probably just need to truncate the time portion.

SELECT d.DAY
     , r.reqport
     , COUNT(c.message) AS numberofsms
     , YEAR(d.datetimein) AS years
     , MONTH(d.datetimein) AS months
     , DAY(d.datetimein) AS days
FROM ( /* Distinct reqport values. */
    SELECT reqport
    FROM [radiomix].[dbo].[chat]
    GROUP BY reqport
) r
CROSS JOIN ( /* Distinct dates. */
    SELECT DATEADD(DD, DATEDIFF(DD, 0, datetimein), 0) AS datetimein, DAY
    FROM [radiomix].[dbo].[chat]
    /* Filter to desired date range. */
    WHERE datetimein >= '2012'
    AND datetimein < '2013'
    GROUP BY datetimein, DAY
) d
LEFT JOIN [radiomix].[dbo].[chat] c
  ON c.reqport = r.reqport 
 AND c.datetimein >= d.datetimein 
 AND c.datetimein < DATEADD(DD, 1, d.datetimein)
GROUP BY d.DAY
       , r.reqport
       , YEAR(d.datetimein)
       , MONTH(d.datetimein)
       , DAY(d.datetimein)
ORDER BY years DESC, months DESC, days DESC
;

If that does not fix the issue, try generating the dates this way.
CROSS JOIN ( /* Distinct dates. */
    SELECT DATEADD(DD, [number], '2012')
         , UPPER(LEFT(DATENAME(DW, DATEADD(DD, [number], '2012')),2))
    FROM master..spt_values
    WHERE [type] = 'P'
    AND DATEADD(DD, [number], '2012') < '2013'
) d(datetimein, DAY)
