There are many ways to learn to code these days. From coding bootcamps like Flatiron School to online courses to totally free beginner resources. The best way to learn to code depends on many factors, but the most important one is you. See what course is best for you.
union all between two table
i have the following query
DAY reqport numberofsms years months days
TH 630590 26 2012 12 27
TH 84448 16 2012 12 27
TH 732222 2 2012 12 27
and the another selection is :
the result
reqport
84448
630590
730165
732265
732222
i want to make a result to get this result :
DAY reqport numberofsms years months days

TH 732265 0 2012 12 27
?????????????
select DAY,reqport,count(message) as numberofsms,Year(datetimein) as years, Month(datetimein) as months, Day(datetimein) as days

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
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.
yes mwvisa1 this is what i want :S but how ??
i have some reqport with null value i want to add this missing reqport and 0 value for numberofsms and ad each years,month,years
hope you can help me )

Try like this:
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.
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
;

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.
If that does not fix the issue, try generating the dates this way.
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)
powerfull please mwvisa1 i will add now new question for month and day ..
because after i run your script i get some field like this
DAY reqport numberofsms years months days

SA 732222 0 2011 1 8
year 2011 and month 1 start with day 8 and not from 1 to 30 or 1 it's depending from
so i should add the all reqport with 0 number of sms and year 2011 and month 1 ..
and same i have like year 2011 or 2011 without a month for example 2 so ..
what should be the modification :
