In my code I have written an update query according to the date. That means, I have created an application for payroll, in that monthly they want to add month leave as two. If it is a new joinee that will separate two. This is the process I have done through my code. Now they want to change the model, that is, if the new joinee date of join has been greater than 15 days it should add one day leave. Please help me to do this. And this is my code befor I used:
UPDATE tbl_emploeedetails
SET elbal = elbal - 2
WHERE employeestatus = 'L'
AND ( Month(doj) = Month(Getdate()) - 1
AND Year(doj) = Year(Getdate())
AND Day(doj) > 25 )
OR ( Month(doj) = Month(Getdate())
AND Year(doj) = Year(Getdate()) )
and this is month leave add query :
update tbl_emploeedetails
set elbal = elbal + 2 where employeestatus = 'L'
You can use something like this
UPDATE YourTable
SET UpdateColumn =
(CASE
WHEN <Condition1> THEN <Expression1>
WHEN <Condition2> THEN <Expression2>
ELSE <Expression3>
END)
Example:
UPDATE YourTable
SET UpdateColumn =
(CASE
WHEN A>B THEN D * 2
WHEN A>C THEN D * 3
ELSE D * 4
END)

I have a query and it shows the months where there is corresponding data. However, I would like to show all of the months in the year and have the months where there are no data shown as zero.
There is my SQL Statement:
SELECT DATENAME(MONTH, hb_Disputes.OPENED) AS MonthValue,
COUNT(CASE WHEN REV_CLS = 2 THEN 1 END) AS SmallCommercialIndust,
COUNT(CASE WHEN REV_CLS <> 2 THEN 1 END) AS Residential
FROM hb_Disputes
WHERE (hb_Disputes.ASSGNTO = 'E099255') AND (YEAR(hb_Disputes.OPENED) = YEAR(GETDATE()))
GROUP BY hb_Disputes.OPENED
And this is my output:
I also have a table name MonthName that shows all of the months in a year and I know I may need to use this to accomplish what I'm trying to achieve but I'm not sure how to get there:
If you have data in the table for all months, but the where clause is filtering it out, then the simplest method is to extend the conditional aggregation:
SELECT DATENAME(MONTH, d.OPENED) AS MonthValue,
SUM(CASE WHEN d.ASSGNTO = 'E099255' AND d.REV_CLS = 2 THEN 1 ELSE 0 END) AS SmallCommercialIndust,
SUM(CASE WHEN d.ASSGNTO = 'E099255' AND d.REV_CLS <> 2 THEN 1 ELSE 0 END) AS Residential
FROM hb_Disputes d
WHERE YEAR(d.OPENED) = YEAR(GETDATE())
GROUP BY DATENAME(MONTH, d.OPENED)
ORDER BY MIN(d.OPENED);
Note: This does not fix the issue in all cases. It should just be a simple way to modify your query -- and will often work.
I want to show top ten customers,sales,margin where customers is registred during this accounting year. The query takes about 65seconds to run and it is not accepted :-(
As you may see i am not good at sql and will be very happy for help to improve the query.

Welcome to the community. You have a good start, but future, it is more helpful if you can provide (as commented), the CREATE table declarations so users know the actual data types. Not always required, but helps.
As for your query layout, it is more common to show the JOIN syntax instead of WHERE showing relations between tables, but that comes in time and practice.
Indexes help and should be based on a combination of both WHERE/JOIN criteria AND Grouping fields. Also, if fields are numeric, then do not 'quote' them, just leave as numbers. For example, your AcYr, AcPr, AcNo. I would think that an account number really would be a string value vs number for accounting purposes.
I would suggest the following indexes on your tables
Table Index
Actr ( AcYr, AcPr, AcNo, R3 )
Actor ( CustNo, CreDt )
The Actr table I have the filtering criteria first and the R3 last to help optimize the GROUP BY. The Actor table by the customer number, then the CreDt (Create date??), and is it really a string, or is it a date field? If so, the date criteria would be something like '2018-09-01' and '2019-04-30'

I am trying to create a query that will group data by CT ID and Date that have all 3 MachineID's (1, 10, and 20) and at least one different Sawing Pattern Name.
This Image shows a highlighted example of the data I'm trying to get back and the code i'm currently using
I'm trying to only show data similar to the highlighted rows in the image (CT ID 501573833) and exclude the data in the rows around it where the Sawing Pattern Name is the same at all 3 MachineID's.
Your description suggests group by and having. The conditions you describe can all go in the having clause:
select ct_id, date
from t
group by ct_id, date
having sum(case when machineid = 1 then 1 else 0 end) > 0 and
sum(case when machineid = 10 then 1 else 0 end) > 0 and
sum(case when machineid = 20 then 1 else 0 end) > 0 and
min(sawing_pattern_name) <> max(sawing_pattern_name)
Seems to me that an EXISTS could be useful here.
SELECT
[CT ID],
[MachineID],
[Sawing Pattern name],
[Time],
CAST([Time] AS DATE) AS [Date]
FROM [DataCollector].[dbo].[Maxicut] t
WHERE EXISTS
(
SELECT 1
FROM [DataCollector].[dbo].[Maxicut] d
WHERE d.[CT ID] = t.[CT ID]
AND CAST(d.[Time] AS DATE) = CAST(t.[Time] AS DATE)
AND d.[MachineID] != t.[MachineID]
AND REPLACE(d.[Sawing Pattern name],',','') != REPLACE(t.[Sawing Pattern name],',','')
);
I have this query where I get totals of different stats from an employee roster table.
SELECT A.rempid AS EmpId,
E.flname,
A.rdo_total,
B.grave_total,
C.sundays,
D.holidays
FROM (SELECT rempid,
Count(rshiftid)AS RDO_Total
FROM rtmp1
WHERE rshiftid = 2
GROUP BY rempid
HAVING Count(rshiftid) > 0) A,
(SELECT rempid,
Count(rshiftid)AS Grave_Total
FROM rtmp1
WHERE rshiftid = 6
GROUP BY rempid
HAVING Count(rshiftid) > 0)B,
(SELECT rempid,
Count(rshiftid) AS Sundays
FROM rtmp1
WHERE Datepart(dw, rdate) = 1
AND rshiftid > 2
GROUP BY rempid
HAVING Count(rshiftid) > 0)C,
(SELECT rempid,
Count(rshiftid) AS Holidays
FROM rtmp1
WHERE rdate IN (SELECT pubhdt
FROM pubhol)
AND rshiftid > 2
GROUP BY rempid
HAVING Count(rshiftid) > 0)D,
(SELECT empid,
[fname] + ' ' + [sname] AS flName
FROM remp1)E
WHERE A.rempid = B.rempid
AND A.rempid = E.empid
AND A.rempid = C.rempid
AND A.rempid = D.rempid
ORDER BY A.rempid
I would like to add a date range into it, so that I can query the database within 2 dates. The rTmp1 table has a column called rDate. I was wondering what the best way to do this. I could add it to a stored procedure and add variable to each select query. Or is there a better way to run the query within a date range.
i think just add an additional where clause item similar to:
AND ( rDate > somedate AND rDate < someotherdate )
Adding the date range to each query is the most direct solution.
Making it a stored procedure is something that can always be done with a query, but has nothing to do with this specific case.
If the number of records resulting from narrowing down your table to the specified date range is substantially less than the entire table, it might be an option to insert these records into a temporary table or a table variable and run your existing query on that table/resultset.
Though I do not have any data to test, you might consider the following query as it is more easy to read and might perform better. But you have to check the results for yourself and maybe do some adjustments.
DECLARE #startDate date = '12/01/2012'
DECLARE #endDate date = DATEADD(MONTH, 1, #startDate)
SELECT
[e].[empid],
[e].[fname] + ' ' + [e].[sname] AS [flName],
SUM(CASE WHEN [t].[rshiftid] = 2 THEN 1 ELSE 0 END) AS [RDO_Total],
SUM(CASE WHEN [t].[rshiftid] = 6 THEN 1 ELSE 0 END) AS [Grave_Total],
SUM(CASE WHEN [t].[rshiftid] > 2 AND DATEPART(dw, [t].[rdate]) = 1 THEN 1 ELSE 0 END) AS [Sundays],
SUM(CASE WHEN [t].[rshiftid] > 2 AND [h].[pubhdt] IS NOT NULL THEN 1 ELSE 0 END) AS [Holidays]
FROM [remp1] [e]
INNER JOIN [rtmp1] [t] ON [e].[empid] = [t].[rempid]
LEFT JOIN [pubhol] [h] ON [t].[rdate] = [h].[pubhdt]
WHERE [t].[rdate] BETWEEN #startDate AND #endDate
GROUP BY
[e].[empid],
[e].[fname],
[e].[sname]
ORDER BY [empid] ASC
I have the next table: code, year, day
I want to find the code of the courses that was taken in 2000 in Sunday and Monday.
So I wrote the next query:
Select DISTINCT dbo.Course.Code
From dbo.Course
Where dbo.Course.CourseYear = 2000 AND
EXISTS (Select * From dbo.course Where (dbo.course.day = 'Sunday' and dbo.Course.CourseYear = 2000))and
EXISTS (Select * From dbo.course Where (dbo.course.day = 'Monday' and dbo.Course.CourseYear = 2000))
It's return me the courses that were given in 2000, in Sunday or Monday. Why?
Is this homework?
The query doesn't work as expected because your query only requires that any course in the year 2000 was on Mondays or Sundays - but it isn't specific to the row you're looking at.
SELECT c1.Code
FROM dbo.Course AS c1
WHERE c1.CourseYear = 2000
AND c1.day = 'Sunday'
AND EXISTS (
SELECT *
FROM dbo.Course AS c2
WHERE (c1.Code = c2.Code) AND (c2.day = 'Monday'))
You need to enforce that the same course record is being checked in both exists statement.
Your exists statement only ensure that there exists any course that was offered in sunday and any course that was offered on monday
Revising your query:
Select DISTINCT dbo.Course.Code
From dbo.Course c
Where dbo.Course.CourseYear = 2000 AND
EXISTS (Select * From dbo.course Where (dbo.course.day = 'Sunday' and dbo.Course.CourseYear = 2000 and dbo.course.Code = c.Code))and
EXISTS (Select * From dbo.course Where (dbo.course.day = 'Monday' and dbo.Course.CourseYear = 2000 and dbo.course.Code = c.Code))
A better written version
select distinct c.code
from
dbo.course c
inner join dbo.course c2 on c.code = c2.code
where
c.CourseYear = 2000
and c2.CourseYear = 2000
and c.Day = 'Monday'
and c2.Day = 'Sunday'
Also note that your schema is not normalized. You should have two tables:
Course (CourseId, Code)
CourseInstance (CourseId, Day, Year)
That's actually not what it's giving you. The way you're using exists, you're asking the server to return each record if ANY records exist in the table that satisfy "Sunday" and 2000, AND if any records exist that satisfy "Monday" and 2000. So the one way to query and get what you're trying to ask is:
select c.Code
from dbo.Course c
where c.CourseYear = 2000
group by
c.Code
having sum(case when c.day = 'Sunday' then 1 else 0 end) > 0
and sum(case when c.day = 'Monday' then 1 else 0 end) > 0
