I have a table like below
Name Year Bonus
---- ----- ------
Ram 2011 1000
Ram 2011 2000
Shyam 2011 'No Bonus'
Shyam 2012 5000
I want to display the total bonus year wise for each person.I tried below query
SELECT [Year],[Ram],[Shyam] FROM
(SELECT Name, [Year] , Bonus FROM Employee )Tab1
PIVOT
(
SUM(Bonus) FOR Name IN (Ram,Shyam)) AS Tab2
ORDER BY [Tab2].[Year]
My Output Should be like below
Name 2011 2012
---- ------ ------
Ram 3000 0
Shyam 'No Bonus' 5000
But it is not working.
Can anyone help me on this?
If your dbms is sql-server you can try to use SUM condition aggregate function in a CTE
then use CAST with coalesce to make it.
;WITH CTE AS(
SELECT Year,Name,
SUM(CASE WHEN Bonus LIKE '%[0-9]%' THEN CAST(Bonus AS DECIMAL) ELSE 0 END) total,
COUNT(CASE WHEN Bonus = 'No Bonus' THEN 1 END) cnt
FROM T
GROUP BY Year,Name
)
SELECT Name,
coalesce(MAX(CASE WHEN Year = 2011 THEN CAST(total AS VARCHAR(50)) END),'No Bonus') '2011',
coalesce(MAX(CASE WHEN Year = 2012 THEN CAST(total AS VARCHAR(50)) END),'No Bonus') '2012'
FROM CTE
GROUP BY Name

If you want to create columns dynamically you can try to use dynamic PIVOT.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
;WITH CTE AS(
SELECT Year,Name,
SUM(CASE WHEN Bonus LIKE '%[0-9]%' THEN CAST(Bonus AS DECIMAL) ELSE 0 END) total,
COUNT(CASE WHEN Bonus = 'No Bonus' THEN 1 END) cnt
FROM T
GROUP BY Year,Name
)
SELECT #cols = STUFF((SELECT distinct ',coalesce(MAX(CASE WHEN cnt > 0 and Year = ' + cast(Year as varchar(5)) + ' THEN ''No Bonus'' WHEN Year = ' + cast(Year as varchar(5)) + ' and cnt = 0 THEN CAST(total AS VARCHAR(50)) END),''0'')' + QUOTENAME(Year)
FROM CTE c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = '
;WITH CTE AS(
SELECT Year,Name,
SUM(CASE WHEN Bonus LIKE ''%[0-9]%'' THEN CAST(Bonus AS DECIMAL) ELSE 0 END) total,
COUNT(CASE WHEN Bonus = ''No Bonus'' THEN 1 END) cnt
FROM T
GROUP BY Year,Name
)
SELECT Name, ' + #cols + '
from CTE
GROUP BY Name'
exec(#query)

According to your problem the following query is what I understood. Not the ideal solution but this will do.
You can modify the query if you need to make it dynamic.
SELECT [Name]
, case when [2011] = 0 then 'No Bonus' when [2011] is null then '0' else cast([2011] as varchar(50)) end as [2011]
, case when [2012] = 0 then 'No Bonus' when [2012] is null then '0' else cast([2012] as varchar(50)) end as [2012]
FROM
(SELECT Name, [Year] , cast(Bonus as int) Bonus FROM Employee)Tab1
PIVOT
(
SUM(Bonus) FOR Year IN ([2011],[2012])) AS Tab2
ORDER BY [Tab2].[Name]
You need to pass 0 in the table though and then modify in the PIVOT
I would just give up on storing numbers as strings. I don't see the difference between 0/NULL and 'No Bonus', except that the latter makes queries prone to really bad type conversion problems.
So, my advice is to do:
SELECT [Year],[Ram],[Shyam]
FROM (SELECT Name, [Year], TRY_CONVERT(int, Bonus) as Bonus
FROM Employee
) e
PIVOT (SUM(Bonus) FOR Name IN (Ram, Shyam)) AS Tab2
ORDER BY [Tab2].[Year] ;
You probably don't like that solution -- although I really do strongly recommend it because I have spent way too many hours debugging problems with numbers and dates stored as strings.
So, if you persist with storing values as string, use conditional aggregation and a bunch of logic:
select year,
coalesce( sum(case when name = 'Ram'
then convert(varchar(255), try_convert(int, bonus))
end),
'No Bonus'
) as Ram,
coalesce( sum(case when name = 'Shyam'
then convert(varchar(255), try_convert(int, bonus))
end),
'No Bonus'
) as Shyam
from employee e
group by year
order by year;
I have a requirement to get the data for rolling next 12 months. This comes with a special condition to show the months with blank data if data does not exist in the database. For example - If data exists only till Jan 2017 then the result query should show Feb 2017 also but with blank data.
Using below query I am able to get the data which exists. I don't want to add any loops to check which month is missing and add those months.
SELECT
SiteCode
,CustomerName
,CalYear
,CalMonth
,CalDay
, CONVERT(DATE,CONVERT(VARCHAR(4),CalYear)+'-'+CONVERT(VARCHAR(2),CalMonth)+'-'+CONVERT(VARCHAR(2),CalDay)) AS CalDate
,MachineDownTimes
,MaterialsDownTimes
,LineBalancingLost
,Others
FROM
dbo.ProcessBackend
WHERE CustomerName = 'ZAS' AND SiteCode = 'HU01'
AND DATEFROMPARTS(CALYEAR, CALMONTH, CALDAY)
BETWEEN DATEFROMPARTS(DATEPART(YEAR, GETDATE()), DATEPART(MONTH, GETDATE()), 1) AND
DATEFROMPARTS(DATEPART(YEAR, (DATEADD(MONTH, 12, GETDATE()))), DATEPART(MONTH, (DATEADD(MONTH, 12, GETDATE()))), 1)
What would be the best option to achieve this in SQL or C#
As already mentioned, these are the steps to achieve your goals:
1) create a months table, since you want to display month data even if data is not present. You can choose something from these answers - I have adapted the shortest and elegant solution from there:
declare #today DATE = GETDATE()
declare #thisMonth DATE = DATEFROMPARTS(YEAR(#today), MONTH(#today), 1)
declare #startMonth DATE = DATEADD(month, -11, #thisMonth)
PRINT 'This month '; PRINT #thisMonth
PRINT 'Start month '; PRINT #startMonth
declare #monthInfo TABLE (BOM DATE)
insert into #monthInfo (BOM)
select top 11 dateadd(month, num, #startMonth) as mon
from (select row_number() over (order by (select 1)) as num
from sys.columns c
) n cross join
(select #startMonth firstdate) const
SELECT * FROM #monthInfo
The results is:
BOM
2015-05-01
2015-06-01
2015-07-01
2015-08-01
2015-09-01
2015-10-01
2015-11-01
2015-12-01
2016-01-01
2016-02-01
2016-03-01
2) create final query by selecting from generated dates and your table
DECLARE #CustomerName VARCHAR(100) = 'ZAS'
DECLARE #SiteCode VARCHAR(32) = 'HU01'
;WITH CTE AS (
SELECT SiteCode, CustomerName, DATEFROMPARTS(CalYear, CalMonth, 1) AS CalMonth,
MachineDownTimes, MaterialsDownTimes, LineBalancingLost, Others
FROM dbo.ProcessBackend
WHERE CustomerName = #CustomerName AND #SiteCode = #SiteCode
)
SELECT #CustomerName, #SiteCode, M.BOM,
SUM(MachineDownTimes), SUM(MaterialsDownTimes), SUM(LineBalancingLost), SUM(Others)
FROM #monthInfo M
LEFT JOIN CTE ON CTE.CalMonth = M.BOM
GROUP BY CTE.CustomerName, CTE.SiteCode, M.BOM
Create default month table which included (Jan -> Dec).
Union default month table with your output table and SUM (those columns you can to show) these column:
(MachineDownTimes
,MaterialsDownTimes
,LineBalancingLost
,Others)
Done.

Okay so here's my issue.
The user can go onto my site and retrieve 8 records at a time, then he/she is given the option to load more. These 8 records can be sorted by a param passed into the proc. Now when I get these 8 records on the front end, I have their ID's (hidden to the user though obviously), but their ID's are not in any specific order because the records are sorted by a variety of possible things.
When they click "Load More", I should be able to get the next 8 records from the database, sorted in the SAME fashion as the first 8 were.
For example, "Give me the top 8 records sorted by age". -> Click Load More -> Give me the next 8 oldest records without showing me the onces I just saw.
How can I call the proc and make sure none from the first result set are returned though? I only want to return 8 records at a time for efficiency reasons.
SELECT TOP 8
m.message,
m.votes,
(geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 as distance,
m.location,
datediff(hour,m.timestamp, getdate()) as age,
m.messageId,
ml.voted,
ml.flagged
FROM
tblMessages m
left join tblIPMessageLink ml on m.messageid = ml.messageid
WHERE
m.timestamp >= DATEADD(day, DATEDIFF(day, 0, #date), 0)
and
m.timestamp < DATEADD(day, DATEDIFF(day, 0, #date), 1)
ORDER BY
CASE WHEN #sort = 'votes1' THEN m.votes END DESC,
CASE WHEN #sort = 'votes2' THEN m.votes END ASC,
CASE WHEN #sort = 'age1' THEN datediff(hour,m.timestamp, getdate()) END ASC,
CASE WHEN #sort = 'age2' THEN datediff(hour,m.timestamp, getdate()) END DESC,
CASE WHEN #sort = 'distance1' THEN (geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 END ASC,
CASE WHEN #sort = 'distance2' THEN (geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 END DESC
END
That's my current query. How would I change it to work with paging?
use row_number
example
call 1
;WITH cte AS(SELECT *,row_number() OVER( ORDER BY name) AS rows FROM sysobjects)
SELECT * FROM cte WHERE ROWS BETWEEN 1 AND 8
ORDER BY rows
call 2
;WITH cte AS(SELECT *,row_number() OVER( ORDER BY name) AS rows FROM sysobjects)
SELECT * FROM cte WHERE ROWS BETWEEN 9 AND 16
ORDER BY rows
of course you want to use parameters instead of hardcoding the numbers, this way you can reuse the query, if the column can be sorted arbitrarily then you might need to use dynamic SQL
edit, here is what it should look like, you probably also want to return the max rownumber so that you know how many rows can be potentially returned
also you can make rows per page dynamic, in that case it would be something like
where Rows between #StartRow and (#StartRow + #RowsPerPage) -1
make sure to read Dynamic Search Conditions in T-SQL Version for SQL 2008 to see how you can optimize this to get plan reuse and a better plan in general
anyway, here is the proc, untested of course since I can't run it here
DECLARE #StartRow INT,#EndRow INT
--SELECT #StartRow =1, #EndRow = 8
;WITH cte AS (SELECT ROW_NUMBER() OVER (ORDER BY
CASE WHEN #sort = 'votes1' THEN m.votes END DESC,
CASE WHEN #sort = 'votes2' THEN m.votes END ASC,
CASE WHEN #sort = 'age1' THEN datediff(hour,m.timestamp, getdate()) END ASC,
CASE WHEN #sort = 'age2' THEN datediff(hour,m.timestamp, getdate()) END DESC,
CASE WHEN #sort = 'distance1' THEN (geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 END ASC,
CASE WHEN #sort = 'distance2' THEN (geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 END DESC
END) AS rows
m.message,
m.votes,
(geography::Point(#latitude, #longitude, 4326).STDistance(m.point)) * 0.000621371192237334 as distance,
m.location,
datediff(hour,m.timestamp, getdate()) as age,
m.messageId,
ml.voted,
ml.flagged
FROM
tblMessages m
left join tblIPMessageLink ml on m.messageid = ml.messageid
WHERE
m.timestamp >= DATEADD(day, DATEDIFF(day, 0, #date), 0)
and
m.timestamp < DATEADD(day, DATEDIFF(day, 0, #date), 1)
)
SELECT *
FROM cte WHERE ROWS BETWEEN #StartRow AND #EndRow
ORDER BY rows
David Hayden has a nice article on paging. You'll just need to keep track of the number of records and offset.
Also you'll still need to merge and resort the records on the client every time they load more
Here's the SP from that article
CREATE PROCEDURE dbo.ShowLog
#PageIndex INT,
#PageSize INT
AS
BEGIN
WITH LogEntries AS (
SELECT ROW_NUMBER() OVER (ORDER BY Date DESC)
AS Row, Date, Description
FROM LOG)
SELECT Date, Description
FROM LogEntries
WHERE Row between
(#PageIndex - 1) * #PageSize + 1 and #PageIndex*#PageSize
END
I'd like to allow my users to setup a schedule for their events. It could be a single day, or for convenience I'd like to allow them to specify a reoccurring event (similar to an Outlook appointment).
For the single event it seems pretty easy (pseudo-code):
Just have a DateOfEvent column that has the date on it.
To grab future events:
Select * from events where DateOfEvent > {DateTime.Now}
But how could I store and query a reoccurring event? I don't need to do times, as I'd just store that seperately, and if they needed a different time I'd just have them create another event. So no: Every wednesday at 5 and thursdays at 3.
Examples:
Every mon, tues, wed, thu, fri, every week
Every wed every week
Every second tuesday of the month
What I used to query
I added a start and end dates. If the user selected a single date I set both start and end dates to the chosen date. I just had to modify the answer's code a bit.
DECLARE
#StartDate SMALLDATETIME,
#EndDate SMALLDATETIME;
SELECT
#StartDate = '20091129',
#EndDate = '20101220';
SELECT
d.CurrentDate,
m.*
FROM
Calendar AS d
INNER JOIN Meet AS m
ON
(
(d.CurrentDate = m.StartDate AND d.CurrentDate = m.EndDate)
OR d.DaysOfTheMonth = m.DayOfTheMonth
OR (d.DaysOfTheWeek = m.DayOfTheWeek AND COALESCE(m.WeekOfTheMonth, d.WeekOfTheMonth) = d.WeekOfTheMonth)
OR d.DaysOfTheWeek IN (1,7) AND m.OnWeekends = 1
OR d.DaysOfTheWeek BETWEEN 2 AND 6 AND m.OnWeekDays = 1
)
-- now you can inner join to the event table
-- to list the name, other details, etc.
WHERE
d.CurrentDate BETWEEN #StartDate AND #EndDate
AND d.CurrentDate BETWEEN m.StartDate AND m.EndDate
ORDER BY d.CurrentDate;
GO
Filling in the Calandar table:
INSERT dbo.Calendar(CurrentDate, DaysOfTheMonth, DaysOfTheWeek, WeekOfTheMonth, IsWeekDay, Even)
SELECT
CurrentDate, DaysOfTheMonth, DaysOfTheWeek,
WeekOfTheMonth = DATEDIFF(WEEK, DATEADD(DAY, 1-DaysOfTheMonth, CurrentDate), CurrentDate) + 1,
CASE WHEN DaysOfTheWeek IN (1, 7) THEN 0 ELSE 1 END AS IsWeekDay,
CASE WHEN w % 2 = 1 THEN 0 ELSE 1 END AS Even
FROM
(
SELECT
CurrentDate,
DaysOfTheMonth = DATEPART(DAY, CurrentDate),
DaysOfTheWeek = DATEPART(WEEKDAY, CurrentDate),
w = DATEPART(WEEK, CurrentDate)
FROM
(
SELECT CurrentDate = DATEADD(DAY, n-1, '20141001')
FROM
(
SELECT TOP 900
n = ROW_NUMBER() OVER (ORDER BY c1.[object_id])
FROM sys.all_columns AS c1
CROSS JOIN sys.all_columns AS c2
ORDER BY n
) AS x) AS y) AS z;
You could do something like this:
CREATE TABLE dbo.EventSchedule
(
EventID INT, -- FOREIGN KEY to event details
EventDate SMALLDATETIME, -- if one-time event
DayOfMonth TINYINT, -- if once a month, e.g. 3rd of every month
DayOfWeek TINYINT, -- if once a week, e.g. every Tuesday = 3
WeekDays BIT, -- if only on weekdays, e.g. 1 = mon-fri
Weekends BIT, -- if only on weekends, e.g. 1 = sat-sun
-- the next two are combined, e.g. 2/2 = 2nd Monday of each month
MonthlyInstance TINYINT,
MonthlyWeekday TINYINT
);
So then if you wanted to find all the events scheduled to happen on a given date, you could do:
DECLARE
#dt SMALLDATETIME,
#dm TINYINT,
#dw TINYINT,
#inst TINYINT;
SELECT
#dt = '20091201',
#dm = DATEPART(DAY, #dt)
#dw = DATEPART(WEEKDAY, #dt),
#inst = DATEDIFF(WEEK, DATEADD(DAY, 1-#dm, #dt), #dt) + 1;
SELECT EventID
FROM dbo.EventSchedule
WHERE EventDate = #dt
OR DayOfMonth = #dm
OR DayOfWeek = #dw
OR (Weekdays = 1 AND #dw BETWEEN 2 AND 6)
OR (Weekends = 1 AND #dw IN (1,7))
OR (MonthlyInstance = #inst AND MonthlyWeekday = #dw);
This is untested (I am posting from a Mac on Thanksgiving, after all), and relies on SET DATEFIRST being the default (where Sunday = 1, Monday = 2, etc). I'm also not 100% confident on the 2nd Tuesday part, as it likely needs some additional math depending on the weekday of the first day of the month. But I thought this could give you a start for the other parts, and I'll come back and revisit when I have a chance.
For some much more complicated options, see: http://www.codeproject.com/KB/database/sqlscheduleselector.aspx

For storing the schedule, take a look at my answer in this question
What is the best way to represent "Recurring Events" in database?
Here I describe how SQL Server stores schedule information in their sysschedules and related tables. They have a really nice schema design which supports all the scheduling cases you are asking about. The documentation on MSDN is also very helpful.
To get all the schedule dates between a date range for outlook type display, take a look at Peter Larsson's blog, he created an excellent sproc to calculate these values.
CREATE PROCEDURE dbo.uspGetScheduleTimes

#startDate DATETIME,
#endDate DATETIME

We have created sql'server job, that periodically (looking at you claim hourly is enough) called some stored procedure. On other turn this procedure selects does 2 things:

Selects ready to fire events from table [B]
