Converting Excel formulas to SQL Case

I would like to ask fro help converting a few excel formulas to sql syntax.

I have the task to use them in a stored procedure, but I am having difficulty converting them.

I have a sample of the excel file and the stored procedure I am using for testing, using hard coded values, same as the first row of the excel file.

There are 5 formulas in the following cells: D, J, K, L, M

Thank you very much for your help.

Formulas:

Number Of Days = IF(SalesOrderTypeCode="Blanket",IF(Today>ContractEndDate,1,IF(Today>ReportEndDate, 0,(IF(Today<ReportStartDate,(+C7ReportEndDate-ReportStartDate+1),(ReportEndDate-Today+1))))),(IF(OR(AND(RequestedDeliveryDate>=ReportStartDate,RequestedDeliveryDate<=ReportEndDate), AND(RequestedDeliveryDate>=Today,RequestedDeliveryDate<=ReportEndDate, Today>ReportStartDate)),1,0)))

Proration Quantity = +NumberOfDays * RemainingDailyQuantity

Original Contract Length 	= IF(SalesOrderTypeCode="Blanket",+ContractEndDate - ContractStartDate + 1, 0)

Remaining Contract Length = IF(SalesOrderTypeCode="Blanket",+ContractEndDate-Today+1,0)

Remaining Daily Quantity = IF(SalesOrderTypeCode="Standard",SalesOrderLineOpenQuantity,IF(Today>ContractEndDate,SalesOrderLineOpenQuantity,SalesOrderLineOpenQuantity/RemainingContractLength))

The formulas are in the excel file I attached to this question.

The columns with formulas are: D, J, K, L, M

I attached the excel file that contains the columns with the formulas, and a stored procedure I started writing, using the values of row 7 in the excel file.

Here they are:
NumberOfDays = case when SalesOrderTypeCode='Blanket' then
	case when Today > ContractEndDate then 1
		when Today > ReportEndDate then 0
		When Today < ReportStartDate then ReportEndDate - ReportStartDate + 1,
		Else ReportEndDate - Today + 1
	End
Else
	case When (RequestedDeliveryDate >= ReportStartDate AND RequestedDeliveryDate <= ReportEndDate) 
				OR (RequestedDeliveryDate >= Today AND RequestedDeliveryDate <= ReportEndDate AND Today > ReportStartDate)
		Then 1,
	else 0 End
End

ProrationQuantity = NumberOfDays * RemainingDailyQuantity

OriginalContractLength = case when SalesOrderTypeCode = 'Blanket' then ContractEndDate - ContractStartDate + 1 Else 0 End

RemainingContractLength = case when SalesOrderTypeCode = 'Blanket' then ContractEndDate - Today + 1 else 0 end

RemainingDailyQuantity = 
	Case when SalesOrderTypeCode = 'Standard' Then SalesOrderLineOpenQuantity
		When Today > ContractEndDate Then SalesOrderLineOpenQuantity
		Else SalesOrderLineOpenQuantity/RemainingContractLength
	End

Wow. Thank you so much.

I tried using the first converted formula for "NumberOfDays" and I get an error:

Implicit conversion from data type datetime to int is not allowed. Use the CONVERT function to run this query.

Is it because the formula performs arithmetic with dates? would you be able to show me how to work around this problem?

Once again, thank you very much

the error comes from this part:

when @Today < @ReportStartDate 
then @ReportEndDate - @ReportStartDate + 1
else @ReportEndDate - @Today + 1

Change the lines as below:
when @Today < @ReportStartDate 
then DATEDIFF(dd, @ReportStartDate, @ReportEndDate) + 1
else DATEDIFF(dd, @Today, @ReportEndDate) + 1

Thank you.

There is something that works different, because in excel I get a different number:

DECLARE @ReportStartDate DATETIME
DECLARE @ReportEndDate DATETIME
SET @ReportStartDate = '03/15/2014'      -- Excel Cell B
SET @ReportEndDate = '03/31/2014'      -- Excel Cell C

SELECT DATEDIFF(dd, @ReportEndDate, @ReportStartDate) + 1  

Gives me -15

But excel calculation gives me 17 as the number of days

Harish VargheseProject LeaderCommented:
It should be
SELECT DATEDIFF (dd, @ReportStartDate, @ReportEndDate) + 1  
NOT SELECT DATEDIFF(dd, @ReportEndDate, @ReportStartDate) + 1

metropiaAuthor Commented:
Harish,

Would the funtion DATEDIFF also be used in the subtraction formula for the column "RemainingContractLength"?

RemainingContractLength = case when SalesOrderTypeCode = 'Blanket' then ContractEndDate - Today + 1 else 0 end

Impeccable work Harish. I really copied and pasted the code, made just a few changes and it worked smoothly.
