Sie könnten auf diese

SELECT 
    SUM(CASE WHEN MONTH(Dt_Expense) = 1 THEN TotalExpense ELSE 0 END) AS January, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 2 THEN TotalExpense ELSE 0 END) AS February, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 3 THEN TotalExpense ELSE 0 END) AS March, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 4 THEN TotalExpense ELSE 0 END) AS April, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 5 THEN TotalExpense ELSE 0 END) AS May, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 6 THEN TotalExpense ELSE 0 END) AS June, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 7 THEN TotalExpense ELSE 0 END) AS July, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 8 THEN TotalExpense ELSE 0 END) AS August, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 9 THEN TotalExpense ELSE 0 END) AS September, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 10 THEN TotalExpense ELSE 0 END) AS October, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 11 THEN TotalExpense ELSE 0 END) AS November, 
    SUM(CASE WHEN MONTH(Dt_Expense) = 12 THEN TotalExpense ELSE 0 END) AS December 
FROM 
    expense 
WHERE 
    Dt_Expense BETWEEN '2017/01/01' AND '2017/12/31';
