Question

I am developing c# application.
I am using OLEDB connections.

I have following two tables>>

payment

AdmissionNumber  | StudName |

       1            John
       2            Smith

paymentDetails

   AdmissionNumber  | RemainingFee |    Date         | Payment

        1                5000         10/10/2012         3000
        1                3000         10/11/2012         2000
        2                4000         15/11/2012         3000
        1                1000         10/12/2012         2000

In this I want to get the table result as following>>

 AdmissionNumber | Name | Date           |RemainingPayment|Payment|
       1           John    10/12/2012          1000         2000

In this case Admission number and date is already provided in the form via textbox and datetimepicker.

Answer 1

In this case Admission number and date is already provided in the form
via textbox and datetimepicker.

So you want to search for a specific Admission number and a date. If so, then try this:

SELECT 
  p.AdmissionNumber,  
  p.Name,   
  pd.Date,
  pd.RemaingFee AS RemainingPayment,
  pd.Payment
FROM Payment p
INNER JOIN PaymentDetails pd ON p.AdmissionNumber = pd.AdmissionNumber
WHERE p.AdmissionNumber = @AdmissionNumberParamFromTxtBox
  AND pd.Date           = @DateParamFromTheotherTextBox;
