Question

I have two tables in my database Requests and Balance tracker which has no relation…. but I want to select data from two tables and bind it two grid…

Requests

EmpID | EmpRqsts | EmpDescription | ApproverID | ApprovedAmount | RequestPriority
   1  | asdfsb   | sadbfsbdf      |     1      |
   2  | asbfd    | sjkfbsd        |     1      |

Balance Tracker

EmpId | BalanceAmnt | LastUpdated | lastApprovedAmount
  1   |    5000     | sdfbk       |
  2   |    3000     | sjbfsh      |

Now I want to update both tables at a time, based on the EmpID. Whenever amount is approved, it should be updated in request table column [ApprovedAmount] and with priority…

When [ApprovedAmount] is updated [BalanceAmnt] Balance Tracker of also should be Updated by adding the amount approved,[LastUpdated],[lastApprovedAmount] should be updated with date and time

Can anyone help me with the query please….

Answer 1

First create a stored procedure to update your [ApprovedAmount] column

create procedure SP_UpdateRequestedAmount
    (@EmpID int,
     @AmountApproved varchar (50),
     @RequestPriority varchar (50))
as
begin
    Update Requests   
    set ApprovedAmount = @AmountApproved,
        Request_Priority = @RequestPriority 
    where
        Emp_ID = @EmpID
end

Then use a triger to update the other table when ever [AmountApproved] column is updated

CREATE TRIGGER tr_ApprovedAmount_UPDATE 
ON Requests   
AFTER UPDATE 
AS 
    --Make sure Priority was changed 
    IF NOT UPDATE(ApprovedAmount) 
        RETURN 

    --Determine if Priority was changed to high 

    -- PUT your queries for Updatating other table 
     declare @Balance_LastUpdated date
     declare @ApprovedDate date

     UPDATE Balance Tracker
     SET Balance Tracker.Balance_BalanceAmount =  Balance Tracker.Balance_BalanceAmount +   PTS_Requests.Request_IsApproved,
         Balance_LastUpdated = @Balance_LastUpdated,
         Balance_LastApproval = @ApprovedDate
     FROM
         Balance Tracker 
     INNER JOIN
         Requests ON Balance Tracker.Emp_ID = Requests.Emp_ID

Hope this helps………
