Timeout expired. The timeout period elapsed prior to completion of the operation

I an a stored procedure which selects files with pagination criteria
In this problem, when run this stored procedure, get an exception
Timeout expired. The timeout period elapsed prior to completion of the operation
How to works again without above exception?
My researches and tries:
I compared same db on two database servers(prod and test). Test server can work and prod one can not.
I changed connecion string to add "connect timeout=30000" (5 mins)
I also added CommandTimeOut=30000 at file list method.
Additional information: Prod's db server and IIS server placed different server. I searced some articles and because of the slow connection or heavier traffic on db server. But I encountered this error at first time on today.
My stored procedure located below

Add OPTION RECOMPILE and transform the non-SARGable where clauses. see http://sommarskog.se/dyn-search.html
eg
((NULLIF(#IlkTarih,'') IS NULL OR (#IlkTarih<=CONVERT(date, DATEADD(day,0,cte.RaporTarih)))))
should be
#IlkTarih is null or cast(#IlkTarih as date)<=cte.RaporTarih

I resolved this issue with adjust memory on SQL Server management studio because of low memory of db server.
If record is high, then query execution can take a long time.

How to make a schedule table query from SQL Server 2012?

I need help to make a schedule table for employee from my table the main problem is the row not start from first row on every column so the row keep continue, see picture below:
we can see that the next column is null on the first row and continue from the last row. this is my query and table relations, you can see it below.
SELECT (SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Tuesday')) AS Selasa,
(SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Wednesday')) AS Rabu,
(SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Thursday')) AS Kamis,
(SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Friday')) AS Jumat,
(SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Sabtu')) AS Saturday,
(SELECT PEGAWAI.NAMAPEGAWAI
WHERE (JADWAL.HARIKERJA = 'Monday')) AS Minggu FROM JADWAL INNER JOIN
JADWALPEGAWAI ON JADWAL.IDJADWAL = JADWALPEGAWAI.IDJADWAL INNER JOIN
PEGAWAI ON JADWALPEGAWAI.IDPEGAWAI = PEGAWAI.IDPEGAWAI WHERE (JADWAL.SHIFT = 'I')

What seems to be causing your query not to behave as you expect, is that you have no GROUP BY clause in your query, which means that you get one row of output for each for (in this case) each row of the JadwalPegawai table.
At a minimum, adding GROUP BY Pegawai.NamaPegawai after your WHERE … clause should fix this, but I think that we can do even better:
Select Min(iif(j.Harikerja = 'Tuesday', p.NamaPegawai, Null)) As Selasa,
Min(iif(j.Harikerja = 'Wednesday', p.NamaPegawai, Null)) As Rabu,
…
From Jadwal As j
Join JadwalPegawai As jp On j.IdJadwal = jp.IdJadwal
Join Pegawai As p On jp.IdPegawai = p.IdPegawai
Where j.Shift = 'I'
Group By p.NamaPegawai;
This should be logically equivalent, but doesn't use subqueries. Hope I didn't make any spelling errors, I'm not too good at bahasa Indonesia...

I want the last entries in my Microsoft SQL Server database but get duplication

My problem is that I want to start a database query which should give me the last (maxDate) entry of every Serial number.
I am working with a Microsoft SQL Server database.
The first picture shows all entries in the database:
After I have run the following code I get this output:
string aQuery = #" SELECT *
FROM (
SELECT SerialNumber, MAX(Date) as MaxDate
FROM eBox_Deploy
GROUP BY SerialNumber
) r
INNER JOIN eBox_Deploy t
ON t.SerialNumber = r.SerialNumber AND t.Date = r.MaxDate";
using (var db = new eBoxDataContext())
{
list.AddRange(db.ExecuteQuery<eBox_Deploy>(bQuery));
}
After picture:
Now my problem is that I have duplicates because they already exists in the database. Distinct doesn't work well because these all have different Id´s.
How can I get them away?

You could use windowed functions:
SELECT *
FROM (SELECT *,
rn = ROW_NUMBER() OVER(PARTITION BY [SerialNumber] ORDER BY [Date] DESC)
FROM eBox_Deploy) AS sub
WHERE rn = 1;
If your [Date] is not unique within SerialNumber group use RANK() to get ties.

Complicated SQL Server query

I am trying to write an SQL (Server) query which will return all events on a current day, and for all events where the column recurring= 1, I want it to return this event on the day it is being held and for the subsequent 52 weeks following the event.
My tables are structured as followed :
Event
{
event_id (PK)
title,
description,
event_start DATETIME,
event_end DATETIME,
group_id,
recurring
}
Users
{
UserID (PK)
Username
}
Groups
{
GroupID (PK)
GroupName
}
Membership
{
UserID (FK)
GroupID (FK)
}
The code I have thus far is as follows :
var db = Database.Open("mPlan");
string username = HttpContext.Current.Request.Cookies.Get("mpUsername").Value;
var listOfGroups = db.Query("SELECT GroupID FROM Membership WHERE UserID = (SELECT UserID from Users WHERE Username = #0 )", username);
foreach(var groupID in listOfGroups)
{
int newGroupID = groupID.GroupID;
var result = db.Query(
#"SELECT e.event_id, e.title, e.description, e.event_start, e.event_end, e.group_id, e.recurring
FROM event e
JOIN Membership m ON m.GroupID = e.group_id
WHERE e.recurring = 0
AND m.GroupID = #0
AND e.event_start >= #1
AND e.event_end <= #2
UNION ALL
SELECT e.event_id, e.title, e.description, DATEADD(week, w.weeks, e.event_start), DATEADD(week, w.weeks, e.event_end), e.group_id, e.recurring
FROM event e
JOIN Membership m ON m.GroupID = e.group_id
CROSS JOIN
( SELECT row_number() OVER (ORDER BY Object_ID) AS weeks
FROM SYS.OBJECTS
) AS w
WHERE e.recurring = 1
AND m.GroupID = #3
AND DATEADD(WEEK, w.Weeks, e.event_start) >= #4
AND DATEADD(WEEK, w.Weeks, e.event_end) <= #5", newGroupID, start, end, newGroupID, start, end
);
This results in when one queries for the date of the event stored in the database, this event and 52 weeks of events are returned. When one queries for the event the week after this one, nothing is returned.

The simplest solution would be to alter the following 2 lines
AND e.event_start >= #4
AND e.event_end <= #5"
to
AND DATEADD(WEEK, w.Weeks, e.event_start) >= #4
AND DATEADD(WEEK, w.Weeks, e.event_end) <= #5"
However, I'd advise putting all this SQL into a stored procedure, SQL-Server will cache the execution plans and it will result in (slightly) better performance.
CREATE PROCEDURE dbo.GetEvents #UserName VARCHAR(50), #StartDate DATETIME, #EndDate DATETIME
AS
BEGIN
-- DEFINE A CTE TO GET ALL GROUPS ASSOCIATED WITH THE CURRENT USER
;WITH Groups AS
( SELECT GroupID
FROM Membership m
INNER JOIN Users u
ON m.UserID = u.UserID
WHERE Username = #UserName
GROUP BY GroupID
),
-- DEFINE A CTE TO GET ALL EVENTS FOR THE GROUPS DEFINED ABOVE
AllEvents AS
( SELECT e.*
FROM event e
INNER JOIN Groups m
ON m.GroupID = e.group_id
UNION ALL
SELECT e.event_id, e.title, e.description, DATEADD(WEEK, w.weeks, e.event_start), DATEADD(WEEK, w.weeks, e.event_end), e.group_id, e.recurring
FROM event e
INNER JOIN Groups m
ON m.GroupID = e.group_id
CROSS JOIN
( SELECT ROW_NUMBER() OVER (ORDER BY Object_ID) AS weeks
FROM SYS.OBJECTS
) AS w
WHERE e.recurring = 1
)
-- GET ALL EVENTS WHERE THE EVENTS FALL IN THE PERIOD DEFINED
SELECT *
FROM AllEvents
WHERE Event_Start >= #StartDate
AND Event_End <= #EndDate
END
Then you can call this with
var result = db.Query("EXEC dbo.GetEvents #0, #1, #2", username, start, end);
This elimates the need to iterate over groups in your code behind. If this is actually a requirement then you could modify the stored procedure to take #GroupID as a parameter, and change the select statements/where clauses as necessary.
I have assumed knowledge of Common Table Expressions. They are not required to make the query work, they just make things slightly more legible in my opinion. I can rewrite this without them if required.

I would check my parameters one at a time against some trivial SQL, just to rule them out as possible culprits. Something like this:
var result = db.Query("select r=cast(#0 as varchar(80))",username);
var result = db.Query("select r=cast(#0 as int)",newGroupID);
var result = db.Query("select r=cast(#0 as datetime)",start);
var result = db.Query("select r=cast(#0 as datetime)",end);

SQL + ASP.Net Efficient paging

My method of paging is inefficient as it calls the same query twice therefore doubling the query time. I currently call the 1 query that joins about 5 tables together with XML search querys to allow for passing List from ASP.net.. then I need to call exactly the same query except with a Count(row) to get the amount of records
For Example (I have removed bits to make it easier to read)
Main Query:
WITH Entries AS (
select row_number() over (order by DateReady desc)
as rownumber, Columns...,
from quote
join geolookup as Pickup on pickup.geoid = quote.pickupAddress
where
quote.Active=1
and //More
)
select * from entries
where Rownumber between (#pageindex - 1) * #pagesize + 1 and #pageIndex * #pageSize
end
Count Query:
select count(rowID)
from quote
join geolookup as Pickup on pickup.geoid = quote.pickupAddress
where
quote.Active=1
and //More
)

You could select the results of your big query into a temp table, then you could query this table for the row number and pull out the rows you need.
To do this, add (after your select statement and before the from)
INTO #tmpTable
Then reference your table as #tmpTable
select row_number() over (order by DateReady desc)
as rownumber, Columns...,
into #tmpTable
from quote
join geolookup as Pickup on pickup.geoid = quote.pickupAddress
where
quote.Active=1
and //More
)
SELECT #Count = COUNT(*) FROM #tmpTable
select * from #tmpTable
where Rownumber between (#pageindex - 1) * #pagesize + 1 and #pageIndex * #pageSize

You can set an output parameter which will hold the number of rows from the first query.
You could do something like
WITH Entries AS (
select row_number() over (order by DateReady desc)
as rownumber, Columns...,
from quote
join geolookup as Pickup on pickup.geoid = quote.pickupAddress
where
quote.Active=1
and //More
)
select #rowcount = max(rownumber) from entries
select * from entries
where Rownumber between (#pageindex - 1) * #pagesize + 1 and #pageIndex * #pageSize
Hope this helps
