SQL function to calculate simple interest - sql

I have worked on the solution, I need some intervention to optimize the solution.
Here is my current script:
create function SI (#Principal int, #roi int , #time int)
returns int
as
begin
declare #Principal_Amt int
--set #Principal_Amt = 10000
set #Principal_Amt = #Principal
declare #rate int
--set #rate=10
set #rate = #roi
declare #time_period int
--set #time_period = 5
set #time_period = #time
declare #Simple_Interest int
set #Simple_Interest = #Principal_Amt * #rate * #time_period / 100
return #Simple_Interest
end
select dbo.SI(10000, 8, 5)


It's only
create function SI(#Principal int = 0, #roi int = 0, #time int = 0)
returns int
as
begin
return (#Principal * #roi * #time /100)
end
You don't need to declare those variables, since you already have them, so use them directly.

Generate Next Alphanumeric Code on SQL Server

I need to create a consecutive sequence of varchar(5) (always 5 chars only) code starting from PREVIOUS code.
For example
'00000', '00001', '00002'...'00009', '0000A', '0000B'...'0000Z', '00010','00011'...'ZZZZZ'.
So if I have #PREVIOUS_CODE = '00000', #NEXT_CODE will be '00001'.
If I have #PREVIOUS_CODE = '00009', #NEXT_CODE will be '0000A'
If I have #PREVIOUS_CODE = '0000Z', #NEXT_CODE will be '00010'
So I need something like that
USE [DATABASE]
GO
CREATE PROCEDURE [dbo].[spGetNextCode]
#PREVIOUS_CODE VARCHAR(5)
AS
DECLARE #NEXT_CODE VARCHAR(5)
DO STUFF
...
SELECT #NEXT_CODE AS NEXT_CODE
GO
Any Help?

Just keep an integer counter in the same table and convert it. I'm using the following SQL Server function in one of my applications:
CREATE FUNCTION [dbo].[GetAlphanumericCode]
(
#number BIGINT,
#leadingzeroes INT = 0
)
RETURNS varchar(255)
AS
BEGIN
DECLARE #charPool varchar(36)
SET #charPool = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'
DECLARE #result varchar(255)
IF #number < 0
RETURN ''
IF #number = 0
SET #result = '0'
ELSE BEGIN
SET #result = ''
WHILE (#number > 0)
BEGIN
SET #result = substring(#charPool, #number % 36 + 1, 1) + #result
SET #number = #number / 36
END
END
IF #leadingzeroes > 0 AND len(#result) < #leadingzeroes
SET #result = right(replicate('0', #leadingzeroes) + #result, #leadingzeroes)
RETURN #result
END
It should be a trivial task to rewrite it as a stored procedure

How to specify the value of the selected field with type date displayed Jalali (Shamsi) instead of date miladi (Gregorian Date) [duplicate]

I want to convert my datetime into Persian datetime in SQL Server. My datetime is in MM/DD/YYYY format. Is there any function in SQL Server to do this as when I want hijri datetime I use this

It is really easy to customize the result of the function.

I know it is too late but maybe useful for others like me having this trouble.
You should write a SQL Function for this conversion like this:
Converting Gregorian to Persian Date
and then use it like this:
SELECT dbo.[UDF_Gregorian_To_Persian]('2013-08-24')

Try this:
select format(getdate() , 'yyyy/MM/dd', 'fa-ir')

You can use the following code to convert the date. This practical and important method has been added to the 2012 version of SQL and can be used.
SELECT FORMAT(GETDATE(), 'yyyy/MM/dd-HH:mm:ss', 'fa')
Result: 1400/02/08-05:08:51
SELECT cast( FORMAT(GETDATE(), 'yyyyMMdd', 'fa') as int)
Result: 14000208
And you can use Format as Follow to get Higri Date:
SELECT FORMAT(GETDATE(), N'yyyy/MM/dd', N'ar')
Result: 1443/06/19

Out of the box, no.
You'd have to write your own UDF, however there is one on CodePlex and another

I believe the best available solution is to use SQLCLR-Jalali-Date-Utility. It has a straightforward installation guide and easy to use functions. Moreover, you can define the format of the converted date without any limitation. in fact, you can use the standard time formatting to define the shape of converted dates.
There are several examples provided inside the GitHub page.
select dbo.GregorianToJalali(GETDATE(),'yyyy/MM/dd hh:mm:ss tt') -- returns 1395/07/01 03:04:33 ب ظ

You can convert it to shamsi using this functions.

And also you can find shamsi months from this function

Thank You.

Function GETNEXTBUSINESSDAY has two parameters, #dDate Datetime and #nDaysAfter Float
When calling it, provide both parameters, for example
dbo.GETNEXTBUSINESSDAY(convert(Datetime,Cast(#nYear as varchar(4)) +'/05/31'), 0);

How to output the results of a stored procedure with a while loop MS SQL Server?

I'm performing some calculations on tsunami's wave time between different radii. I'm having trouble outputting the results of the stored procedure into a table. The output I get is a blank table without any data stored. The log says "0 rows affected". For some reason my inputs and outputs are not registering. I thinking it could have something to do with the way I'm using the loop inside to SP.
CREATE PROCEDURE SP_Tsunami
(
#oceanDepth int,
#radii1 int,
#radii2 int,
#tsunamiSpeed int OUTPUT,
#tsunamiTimeDifference int OUTPUT
)
AS
BEGIN
SET #tsunamiSpeed = sqrt(32.1725 * #oceanDepth) * (60.0/88.0);
Truncate Table dbo.Tsunami
DECLARE #i int
SET #i = 0;
WHILE (#i <= 10000)
BEGIN
INSERT INTO dbo.Tsunami (Radius, Wavetime)
VALUES
(#i, (#i / #tsunamiSpeed))
SET #i = #i + 100;
END
DECLARE #tsunamiTime1 int
DECLARE #tsunamiTime2 int
SET #tsunamiTime1 = (Select Wavetime From Tsunami WHERE Radius = #radii1);
SET #tsunamiTime2 = (Select Wavetime From Tsunami WHERE Radius = #radii2);
SET #tsunamiTimeDifference = (#tsunamiTime2 - #tsunamiTime1);
END
/* Outputs */
DECLARE #Out_tsunamiSpeed int
DECLARE #Out_tsunamiTimeDifference int
/* Inputs */
DECLARE #IN_oceanDepth int
DECLARE #IN_radii1 int
DECLARE #IN_radii2 int
SET #IN_oceanDepth = 15088;
SET #IN_radii1 = 2500;
SET #IN_radii2 = 7500;
Execute SP_Tsunami #oceanDepth = #IN_oceanDepth, #radii1 = #IN_radii1, #radii2 = #IN_radii2, #tsunamiSpeed = #Out_tsunamiSpeed OUTPUT, #tsunamiTimeDifference = #Out_tsunamiTimeDifference OUTPUT

Doesn't make much sense to insert the data into table and then read it from there. All the rows you are inserting into your table eventually only one row is being read from the table to assign values to variables.
Also change the procedure name prefix from sp_ to something else, sp_ is system stored procedure prefix.
I have changed the procedure definition a little bit hope it makes sense.
ALTER PROCEDURE SP_Tsunami
(
#oceanDepth int,
#radii1 int,
#radii2 int,
#tsunamiSpeed int OUTPUT,
#tsunamiTimeDifference int OUTPUT
)
AS
BEGIN
SET #tsunamiSpeed = sqrt(32.1725 * #oceanDepth) * (60.0/88.0);
DECLARE #tsunamiTime1 int
DECLARE #tsunamiTime2 int
SET #tsunamiTime1 = #radii1 / #tsunamiSpeed;
SET #tsunamiTime2 = #radii2 / #tsunamiSpeed;
SET #tsunamiTimeDifference = (#tsunamiTime2 - #tsunamiTime1);
END
GO
Execute the procedure with your provided data.
/* Outputs */
DECLARE #Out_tsunamiSpeed int
DECLARE #Out_tsunamiTimeDifference int
/* Inputs */
DECLARE #IN_oceanDepth int
DECLARE #IN_radii1 int
DECLARE #IN_radii2 int
SET #IN_oceanDepth = 15088;
SET #IN_radii1 = 2500;
SET #IN_radii2 = 7500;
Execute SP_Tsunami #oceanDepth = #IN_oceanDepth
, #radii1 = #IN_radii1
, #radii2 = #IN_radii2
, #tsunamiSpeed = #Out_tsunamiSpeed OUTPUT
, #tsunamiTimeDifference = #Out_tsunamiTimeDifference OUTPUT
SELECT #Out_tsunamiSpeed AS Out_tsunamiSpeed
,#Out_tsunamiTimeDifference AS Out_tsunamiTimeDifference
Result Set:

Function returning null

ALTER FUNCTION [dbo].[getCourseCost]
(
#CourseCode varchar(50),
#Year nchar(10),
#Period nchar(10)
)
RETURNS int
AS
BEGIN
DECLARE #Pnr_personal varchar(50)
DECLARE #Timlön_personal int
DECLARE #Antal_timmar_personal int
DECLARE #Kostnad_personal int
DECLARE #Kostnad_labass int
SELECT #Pnr_personal = Personnummer FROM Bemannas_Av WHERE Period = #Period AND Läsår = #Year AND Kurskod = #CourseCode
SELECT #Timlön_personal = Timlön FROM Personal WHERE Personnummer = #Pnr_personal
SELECT #Antal_timmar_personal = Antal_Timmar FROM Bemannas_Av WHERE Period = #Period AND Läsår = #Year AND Kurskod = #CourseCode
SELECT #Kostnad_labass = (Antal_timmar * Timlön) FROM Labass WHERE Period = #Period AND Läsår = #Year AND Kurser = #CourseCode
SET #Kostnad_personal = #Timlön_personal * #Antal_timmar_personal
IF #Kostnad_personal = NULL
BEGIN
SET #Kostnad_personal = 0
END
IF #Kostnad_labass = NULL
BEGIN
SET #Kostnad_labass = 0
END
RETURN #Kostnad_personal + #Kostnad_labass
END
This keeps returning NULL even though none of the used values are NULL in the database.

This part has a problem #Kostnad_personal=null means nothing .
IF #Kostnad_personal is NULL
BEGIN
SET #Kostnad_personal = 0
END
IF #Kostnad_labass is NULL
BEGIN
SET #Kostnad_labass = 0
END
Or use this :
RETURN ISNULL(#Kostnad_personal,0) + ISNULL(#Kostnad_labass,0)
