How can I implement MS SQL 2014 Stored Procedure - sql-server

Question

I am new to MS SQL 2014 stored procedure. I have a table as shown below. I want to create a stored procedure.
I design my stored procedure but I feel so difficult that I can’t even start. Can anyone help me how can I do that?
I have to send CardNo, CardPassword and the PosSerialNo to SQL store procedure. In return I need to get customer name, surname and the amount.
SENDING: CardNo, CardPass, PosSerialNo
RECEVING:
If Sending.CardPass = CardPasswordTable.Password
Do the following:
If successful I get: CustomerName, CustomerSurname and Amount
If not I get: “No Data Found”
MY TABLES:
1) CardIssueTable:
Columns:
CardId, CardNo, CustId
2) CustomerTable:
Columns:
CustId, CustName, CustSurname
3) PosTable:
Columns:
PosId, PosSerial, PosLocation
4) PaymentTable:
Columns:
PaymentId, PaymentLoaction, PaymentAmount
5) CardPasswordTable:
Columns:
PassId, Password
Edited:
Here is my Stored Procedure. When I execute I get an error.
Store Procedure:
USE [LTKB_Card]
GO
/****** Object: StoredProcedure [dbo].[CardCustomerControl] Script Date: 2.03.2016 10:03:15 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

/*parameters*/
ALTER Procedure [dbo].[CardCustomerControl](
#CardNo varchar(50),
#CardPass varchar(10),
#PosSerialNo varchar(50)
)
AS
BEGIN
DECLARE /*internal of sp*/
#CustName varchar(100),
#CustId int,
#CustSurName varchar(100),
#Amout int,
#PosId int,
#PassId int

INNER JOIN PAYMENT PT on P.PosLocation=PT.PAYID

if (#CustId is not null and #PassId is not null and #PosId is not null)
begin
select #CustName CustName, #CustSurName CustSurname , #Amout Amount
end
else
begin
select 'NoDataFound'
end
END
Execute Statement:
USE [LTKB_Card]
GO
DECLARE #return_value int
EXEC #return_value = [dbo].[CardCustomerControl]
#CardNo = N'5852354822730001',
#CardPass = N'jSCm6xkBpK',
#PosSerialNo = N'RR-312-001387'
SELECT 'Return Value' = #return_value
GO
Error:
Msg 248, Level 16, State 1, Procedure ElitcardCustomerControl, Line 21
The conversion of the varchar value '5852354822730001' overflowed an
int column.

And here are the relationship of the tables:

Answer 1

Looking at the data model this line
INNER JOIN CUSTOMERS CUS ON C.CardCustomer=CUS.CustomerName
Is joining a string to an integer. I can't look at the data to see if this is the exact problem but according to your model the join you want is this:
INNER JOIN CUSTOMERS CUS ON C.CardCustomer=CUS.CUSTID
This is a standard relationship -- I've no idea why you felt the Customer's name was the field to join to.

Answer 2

I truly hope you do not store password in plain text, and I don't get all relations between your tables (for example where is relation between postable and paymenttable, between passwordtable and cartable), but I give you an example of SP you needed. Don't forget IT'S JUST EXAMPLE.
CREATE PROCEDURE dbo.spnamegoeshere
#CardNo int,
#CardPass nvarchar(8),
#PosSerialNo nvarchar(8)
AS
BEGIN
--Check if password is Sending.CardPass = CardPasswordTable.Password
IF (SELECT ISNULL(PassId,0) FROM CardPasswordTable WHERE Password = #CardPass) != 0
BEGIN
-- If successful you get: CustomerName,
-- CustomerSurname and Amount
-- not sure of table relations
SELECT ct.CustomerName, ct.CustomerSurname, pat.PaymentAmount
FROM CardIssueTable cit
INNER JOIN CustomerTable ct ON cit.CustId = Ct.CustId
LEFT JOIN PosTable pt ON pt.PosSerial = #PosSerialNo
LEFT JOIN PaymentTable pat ON pt.PosLocation = pat.PaymentLoaction
WHERE CardNo = #CardNo
END
ELSE
BEGIN
--If not you get: “No Data Found”
SELECT 'No Data Found'
END
END
