Try the below - without assigning some value you define a condition like - and t3.MNAME + cast(t3.N as nvarchar) and t3.NAME
Also, it is best to use explicit JOIN

SQL Server : searching for occurrences in different months

I am trying to do a project which uses Visifire to display graphed data. It takes in a single DataTable. I need to create an SQL query that searches a date column for a particular month (format is: Friday, 03 November 2017) and then stores how many times that month is repeated. It has to do this for all 12 months. This is done in C# in visual studio. Currently, it displays no data on the line graph.
public DataTable ReadDataMonthlyBooked()
{
// Declare references (for table, reader and command)
DataTable monthlyBookedTable = new DataTable();
SqlDataReader reader;
SqlCommand command;
string selectString = "SELECT COUNT (BookingNum) AS Bookings "
+ "FROM Booking "
+ "WHERE Booking.EndDate LIKE 'January' "
+ "AND Booking.EndDate LIKE 'February' "
+ "AND Booking.EndDate LIKE 'March' "
+ "AND Booking.EndDate LIKE 'April' "
+ "AND Booking.EndDate LIKE 'May' "
+ "AND Booking.EndDate LIKE 'June' "
+ "AND Booking.EndDate LIKE 'July' "
+ "AND Booking.EndDate LIKE 'August' "
+ "AND Booking.EndDate LIKE 'September' "
+ "AND Booking.EndDate LIKE 'October' "
+ "AND Booking.EndDate LIKE 'November' "
+ "AND Booking.EndDate LIKE 'December'";
try
{
// Create a new command
command = new SqlCommand(selectString, cnMain);
// open the connection
cnMain.Open();
command.CommandType = CommandType.Text;
reader = command.ExecuteReader();
// read data from readerObject and load in table
monthlyBookedTable.Load(reader);
reader.Close(); //close the reader
cnMain.Close(); //close the connection
return monthlyBookedTable;
}
catch (Exception ex)
{
return (null);
}
}
This is the current SQL query I have and I hope its hopelessly wrong with logic errors but I do not know SQL well enough.

select 'Friday, 03 November 2017'
select cast('03 November 2017' as date)
select SUBSTRING('Friday, 03 November 2017', CHARINDEX(',', 'Friday, 03 November 2017') + 2, 100)
select cast(SUBSTRING('Friday, 03 November 2017', CHARINDEX(',', 'Friday, 03 November 2017') + 2, 100) as date)
select datepart(month, cast(SUBSTRING('Friday, 03 November 2017', CHARINDEX(',', 'Friday, 03 November 2017') + 2, 100) as date))
select datepart(month, cast(Booking.EndDate, CHARINDEX(',', Booking.EndDate) + 2, 100) as date))
, COUNT (BookingNum) AS Bookings "
from booking
group by datepart(month, cast(Booking.EndDate, CHARINDEX(',', Booking.EndDate) + 2, 100) as date))

You'll need a group by, like this
SELECT COUNT(BookingNum) as Bookings, MONTH(EndDate) as Month
FROM Booking
GROUP BY MONTH(EndDate)
But as your EndDate is a varchar, you'll have to extract the month
SELECT COUNT(BookingNum) as Bookings
, SUBSTRING(EndDate,
CHARINDEX(',',EndDate) + 4,
CHARINDEX(' ',EndDate, CHARINDEX(',',EndDate) + 5) - CHARINDEX(',',EndDate) + 4)
FROM Booking
GROUP BY SUBSTRING(EndDate,
CHARINDEX(',',EndDate) + 4,
CHARINDEX(' ',EndDate, CHARINDEX(',',EndDate) + 5) - CHARINDEX(',',EndDate) + 4)
There may be a better way to do this (cursors maybe?) but basically you want to get the location of the first ',' and add 4 to get the month (assuming the date is always 2 digits like in your example) and then use that as a start index for a search of the first blank (that'll be the end of the month name) and substract the first index we found to get the length fo the month.
So, basically, just change the date to a DATE field
or cast it
SELECT COUNT(BookingNum) as Bookings, MONTH(CONVERT(DATE, EndDate)) as Month
FROM Booking
GROUP BY MONTH(CONVERT(DATE, EndDate))
But I don't know if the format you are using will be interpreted correctly by the engine.

The error is in your SQL statement.
SELECT
COUNT(BookingNum) AS Bookings
FROM
Booking
WHERE
Booking.EndDate LIKE '%January%',
AND Booking.EndDate LIKE '%February%',
AND Booking.EndDate LIKE '%March%',
AND Booking.EndDate LIKE '%April%',
AND Booking.EndDate LIKE '%May%',
AND Booking.EndDate LIKE '%June%',
AND Booking.EndDate LIKE '%July%',
AND Booking.EndDate LIKE '%August%',
AND Booking.EndDate LIKE '%September%',
AND Booking.EndDate LIKE '%October%',
AND Booking.EndDate LIKE '%November%',
AND Booking.EndDate LIKE '%December%',
You try to get a record where the month is every month in the year at the same time.
If I'm right, you try to get the number of bookings per month.
So it should look something much more like
SELECT
SUM(CASE WHEN Booking.EndDate LIKE '%January%' THEN 1 ELSE 0 END) AS JanuaryBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%February%' THEN 1 ELSE 0 END) AS FebruaryBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%March%' THEN 1 ELSE 0 END) AS MarchBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%April%' THEN 1 ELSE 0 END) AS AprilBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%May%' THEN 1 ELSE 0 END) AS MayBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%June%' THEN 1 ELSE 0 END) AS JuneBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%July%' THEN 1 ELSE 0 END) AS JulyBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%August%' THEN 1 ELSE 0 END) AS AugustBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%September%' THEN 1 ELSE 0 END) AS SeptemberBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%October%' THEN 1 ELSE 0 END) AS OctoberBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%November%' THEN 1 ELSE 0 END) AS NovemberBookings,
SUM(CASE WHEN Booking.EndDate LIKE '%December%' THEN 1 ELSE 0 END) AS DecemberBookings
FROM
Booking

Calculate Monday as first day of the week with a stored procedure

I have this C# code to pull up the number of postings created within the last week, which is working fine. But it's pulling up count from "last 7 days"; what I want to do is to set the first day of the week to "Monday" so that when we pull up the count of posting for "week", it should pull up the number from "monday to sunday" instead of default "last 7 days".
I created a class to set Monday as the 1st day of the week, but what I want to know is how can I (if I can) encapsulate that method in this code to simply pull count of posting etc
Here is my code:
if (ds.Tables[0] != null && ds.Tables[0].Rows.Count > 0)
{
lblJobPostings.Text = ds.Tables[0].Rows[0]["new_job_posting_this_week"].ToString();
}
if (ds.Tables[1] != null && ds.Tables[1].Rows.Count > 0)
{
lblNewEmployers.Text = ds.Tables[1].Rows[0]["new_employer_this_week"].ToString();
}
if (ds.Tables[2] != null && ds.Tables[2].Rows.Count > 0)
{
lblNewInstitutes.Text = ds.Tables[2].Rows[0]["new_institutes_this_week"].ToString();
}
public static DateTime CallFirstDayOfWeek(DateTime input)
{
int Delta = (7 - (DayOfWeek.Monday - input.DayOfWeek)) % 7;
return input.AddDays(-Delta);
}
Stored procedure:
select COUNT(od.id) [new_job_posting_this_week]
from rs_job_posting od
where od.date_created = GETDATE()-7

Try this in your Stored Procedure:
DECLARE #CurrentWeekday AS INT
DECLARE #LastSunday AS DATETIME
DECLARE #LastMonday AS DATETIME
SET #CurrentWeekday = DATEPART(WEEKDAY, GETDATE())
// Count backwards from today to get to the most recent Sunday.
// (#CurrentWeekday % 7) - 1 will give the number of days since Sunday;
// -1 negates for subtraction.
SET #LastSunday = DATEADD(DAY, -1 * (( #CurrentWeekday % 7) - 1), GETDATE())
// Monday is obviously one day after last Sunday.
SET #LastMonday = DATEADD(DAY, 1, #LastSunday)
SELECT COUNT(od.id) [new_job_posting_this_week]
FROM rs_job_posting od
WHERE od.date_created >= #LastMonday

select COUNT(od.id) [new_job_posting_this_week]
from rs_job_posting od
where od.date_created Between Convert(DateTime, DATEADD(D,-7,GETDATE())) And Convert(DateTime, GetDate())
To select 7 days starting on say last Monday, iterate through the last 7 days in C# until you hit Monday, then pass that date into the SQL Proc.
for (int i = 0; i < 7; i++)
{
DateTime mydate = DateTime.Now.AddDays(-1);
if (mydate.DayOfWeek == DayOfWeek.Monday)
{
//call sp here
}
}

sum of columns that are already sum in sql

SELECT DISTINCT emp_no, sum(CASE WHEN isnull(PresAbs,0)='WO' THEN 1 ELSE 0 END) WO,
sum(CASE WHEN isnull(PresAbs,0)='WP' THEN 1 ELSE 0 END) WP,
sum(CASE WHEN isnull(PresAbs,0)='HL' THEN 1 ELSE 0 END) HL,
sum(CASE WHEN isnull(PresAbs,0)='A' THEN 1 ELSE 0 END) A,**sum(WO+WP+HL+A)**
from TRN_ATTN072013 WHERE CONVERT(varchar,Tdate,112)>'20130712' and CONVERT(varchar,Tdate,112)<'20130717'
group by emp_no
ORDER BY emp_no
i want to sum up this columns WO,WP,HL,A how do i sum these columns

If this is SQL server then you can use CTE
with tablesum as
(
SELECT DISTINCT emp_no, sum(CASE WHEN isnull(PresAbs,0)='WO' THEN 1 ELSE 0 END) WO,
sum(CASE WHEN isnull(PresAbs,0)='WP' THEN 1 ELSE 0 END) WP,
sum(CASE WHEN isnull(PresAbs,0)='HL' THEN 1 ELSE 0 END) HL,
sum(CASE WHEN isnull(PresAbs,0)='A' THEN 1 ELSE 0 END) A
from TRN_ATTN072013
WHERE CONVERT(varchar,Tdate,112) > '20130712' and CONVERT(varchar,Tdate,112) < '20130717'
group by emp_no
)
select t.*, t.WO + t.WP + t.HL + t.A
from tablesum t
order by t.emp_no

in mysql ;)
SELECT emp_no, wo+wp+hl+A FROM
(SELECT DISTINCT emp_no, sum(CASE WHEN isnull(PresAbs,0)='WO' THEN 1 ELSE 0 END) WO,
sum(CASE WHEN isnull(PresAbs,0)='WP' THEN 1 ELSE 0 END) WP,
sum(CASE WHEN isnull(PresAbs,0)='HL' THEN 1 ELSE 0 END) HL,
sum(CASE WHEN isnull(PresAbs,0)='A' THEN 1 ELSE 0 END) A,**sum(WO+WP+HL+A)**
from TRN_ATTN072013 WHERE CONVERT(varchar,Tdate,112)>'20130712' and CONVERT(varchar,Tdate,112)<'20130717'
group by emp_no
ORDER BY emp_no) AS SUB_Q;

How to Nested Case in Select SQL?

I have this select Case SQL statement which compute the totalvolume of a given quantity.
SELECT
DropshipPackinglist.CaseNumber as 'CASE NO.',
DropshipPackinglist.ItemNumber as 'BOM NO.',
DropshipPackinglist.Quantity as 'QTY',
CASE
WHEN DropshipPackinglist.Quantity >=31 and DropshipPackinglist.Quantity <= 36 then '1090x730x1460'
WHEN DropshipPackinglist.Quantity >=25 and DropshipPackinglist.Quantity <= 30 then '1090x730x1230'
WHEN DropshipPackinglist.Quantity >=19 and DropshipPackinglist.Quantity <= 24 then '1090x730x1000'
WHEN DropshipPackinglist.Quantity >=13 and DropshipPackinglist.Quantity <= 18 then '1090x720x790'
WHEN DropshipPackinglist.Quantity >=7 and DropshipPackinglist.Quantity <= 17 then '1090x720x570'
WHEN DropshipPackinglist.Quantity >=1 and DropshipPackinglist.Quantity <= 6 then '1090x720x350'
ELSE 'Unkown'
end
as 'TOTAL VOLUME (MM3)'
FROM DropshipPackinglist INNER JOIN
HuaweiDescription ON DropshipPackinglist.ItemNumber = HuaweiDescription.ItemNumber
WHERE (DropshipPackinglist.BatchCode LIKE '%0005041007100AHWA11HG')
-------------------------------------------------------------------------------------------
Result:
CaseNumber ItemNumber Quantity TotalVolume
1 52411573 5 1090x720x350
1 52411576 20 1090x730x1000
2 52411576 36 1090x730x1460
-------------------------------------------------------------------------------------------
Now is, i want to group casenumber and result with only one totalvolume.
And the result will be this one.
CaseNumber ItemNumber Quantity TotalVolume
1 52411573 5 1090x730x1230 -- sum(casenumber 1)=25
1 52411576 20 1090x730x1230 --
2 52411576 36 1090x730x1460

If you need just one row per caseNumber then use
SELECT CaseNumber, Quantity, SUM(ItemNumber) TotalVolume
FROM (...YourOriginalQuery...)
GROUP BY CaseNumber, Quantity
If you need all rows but want also report Total per case number then use the following query:
SELECT CaseNumber, ItemNumber, Quantity,
SUM(ItemNumber) OVER(PARTITION BY CaseNumber) TotalVolume
