Have a look here[^].
A persisted column, that'd be a computed/calculated field? Are you sure that's a good idea to use as a primary key?

Hi guys,

So yearly will have 52 weeks. My financial year will start every year October to next year September end.
EX my Financial year 2012-13 Start date will be 01/10/2012 end date will be 30/09/2013.
Any help will be appreciated.
Thanks and regards
Vishwa

Look into DATEPART that will give you the week number of the date within the year. Count the issues and group by the week datepart

Sum up want ever you want and make group by with datepart.

What have you tried? What is the error that you get? If you expect someone to write the function for you, then you're in the wrong place.

What precisely are you expecting us to do with this information? You need to supply the script for the function and the error you are getting for us to help you!

What I have nothing better to do than write your code for you tsk tsk not going to happen I'm afraid. How can you expect to learn if you don't research and try and do the coding, getting help when you stumble.

try something like
CREATE FUNCTION func_check_seat_availability
(
@in_bUS_No int,
@in_DateOfJourney datetime,
@in_NoOfAdults int,
@in_NoOfChildren int
)
RETURNS decimal(36,30)
AS
BEGIN
--considering 64 is the total count of bus
declare @value decimal(36,30)
select
@value=case when sum(@in_NoOfAdults+@in_NoOfChildren) >= 34 then 0
when sum(@in_NoOfAdults+@in_NoOfChildren) < 14 then 1
end
from Details where BusNo=@in_bus_No and DateOfJourney=@in_DateOfJourney
return @value
END

Good Day
i have been hit by this error this night.
I have a UDF defined like this
CREATE FUNCTION [dbo].[funcFormatPercentages_Extended]
(
@parPercentageToBeFormatted nvarchar(20)
)
RETURNS nvarchar(20)
AS
BEGIN
RETURN CAST(CAST(convert(float,@parPercentageToBeFormatted)* 100 AS decimal(4, 1)) AS nvarchar(5)) + N'%'
END
so i will call the UDF with the value like this
select [dbo].[funcFormatPercentages_Extended_numeric]('-43.4703076923077')
OR
select [dbo].[funcFormatPercentages_Extended_numeric]('36.403813624481')
i get an Error
Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type nvarchar.
I tried to change the datatypes and Precision around , but still the error.
Thanks

A guess only, try removing the N'%' and see if it makes a difference. % is an operator and the interpretor may be making a mistake on the operation.

decimal(4, 1) means a number with three digits before the decimal point and one digit after:
http://msdn.microsoft.com/en-gb/library/ms187746.aspx[^]
Based on your provided inputs: 36.403 * 100 = 3640.3
Therefore, your result requires four digits before the decimal point, so the precision should be 5:
RETURN CAST(CAST(CONVERT(float, @parPercentageToBeFormatted) * 100 AS decimal(5, 1)) AS nvarchar(5)) + N'%'

<pre>hi all below is my Store Proc
SELECT vb.Sno,
vb.Vehicle_Number,
vb.Vehicle_Booking_Date,
vb.Time_From,
vb.Time_To,
vb.Vehicle_Used_By,
vb.Cost_Code,
vb.Budget_Line,
lb.Vehicle_Number,
lb.Vehicle_Booking_Date,
lb.Time_From,
lb.Time_To,
lb.KM_Start,
lb.KM_End,
lb.Vehicle_Used_By,
lb.Cost_Code,
lb.Budget_Line
FROM mtblVehicle_Booking vb
LEFT JOIN mtblLog_Book lb
ON vb.Sno = lb.Sno
where vb.Vehicle_Number = @Vehicle_Number
AND DATEPART(MONTH,vb.Vehicle_Booking_Date) = MONTH(getdate())
it is working fine. But here I need to put a condition, it should give priority to mtblLog_Book means if mtblLog_Book having data then it should show from mtblLog_Book table otherwise it should shows data from mtblVehicle_Booking for a particular Sno.
Actually firstly on the behalf of mtblVehicle_Booking I am binding a Gridview after updating the data it should show the data from mtblLog_Book.
So let me know please how to put a condition in my sp.
Thanks</pre>

Use a Case When or IsNull condition like this:
SELECT isnull(lb.somefield,vb.anotherfield) as columnname
FROM mtblVehicle_Booking vb
LEFT JOIN mtblLog_Book lb
ON vb.Sno = lb.Sno If lb.somefield is null it will be replaced by vb.anotherfield

your query may be right, let me complete my sentence. according to you query it will show the not null columns, Yes I need that,
but suppose I update vehicle_no in LogBook, now both Vehcile_Booking table and LogBook tabel both have Different Vehicle_no, but after updation I just want to show it from LogBook table instead of Vehicle_Booking table.
|
|
|
|

Did you actually try what Jorgen wrote, the isnull test does exactly what you are asking for:
select ISNULL(LogBook, Vehcile_Booking) from .. .
Will test logbook and return a non null result, if it is null then it will return vehicle_booking.
