Answer 1

If you have tables on the database this is what you do:

INSERT INTO [tblMGT247FeeAccruals] ([PortfolioID], [TransactionDate], [SettlementDate], [TransactionValue]) 
VALUES (@PortfolioID, @TransactionDate, @SettlementDate, @TransactionValue); SCOPE_IDENTITY())

UPDATE [tblMGT247FeeAccruals] 
SET [PortfolioID] = @PortfolioID, [TransactionDate] = @TransactionDate,   [SettlementDate] = @SettlementDate, [TransactionValue] = @TransactionValue 
WHERE AccruedFeeID = @AccruedFeeID

DELETE 
FROM tblMGT247FeeAccruals
Where AccruedFeeID = @AccruedFeeID
