You need to add id column on group by

For Version <= 5.7

Query: 

select 
    coalesce(id, 'Total') as id,
    date,
    customer,
    sum(amount) as amount
from
    mytable
group by date, customer, id with ROLLUP
having customer is not null;

Result: 

id    | date       | customer | amount
:---- | :--------- | :------- | -----:
3     | 2017-09-18 | A        |      1
7     | 2017-09-18 | A        |      1
10    | 2017-09-18 | A        |      1
13    | 2017-09-18 | A        |      1
16    | 2017-09-18 | A        |      1
Total | 2017-09-18 | A        |      5
11    | 2017-09-18 | B        |     20
15    | 2017-09-18 | B        |     40
Total | 2017-09-18 | B        |     60
2     | 2017-09-18 | C        |     90
Total | 2017-09-18 | C        |     90
1     | 2017-09-19 | B        |     10
4     | 2017-09-19 | B        |     15

8     | 2017-09-19 | B        |      2
Total | 2017-09-19 | B        |     50
9     | 2017-09-19 | C        |     11
12    | 2017-09-19 | C        |      9
14    | 2017-09-19 | C        |     10
Total | 2017-09-19 | C        |     30

For Version > 5.7

Query:

select 
    coalesce(id, 'Total') as id,
    date,
    customer,
    sum(amount) as amount
from
    mytable
group by date, customer, id with ROLLUP
having grouping(customer) = 0;

Result:

id    | date       | customer | amount

Total | 2017-09-18 | B        |     60
2     | 2017-09-18 | C        |     90
Total | 2017-09-18 | C        |     90

6     | 2017-09-19 | B        |     18
8     | 2017-09-19 | B        |      2
Total | 2017-09-19 | B        |     50

14    | 2017-09-19 | C        |     10
Total | 2017-09-19 | C        |     30

Note: When using group by without ERROR 1055 you need to set as

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

I think below query will solve your problem.

SELECT IF(temp.date IS NULL, 'Total', temp.Id), temp.Date, temp.Customer, temp.Amount
FROM
     (Select group_concat(Mytable.Id),
             Mytable.Date,
             Mytable.Customer,
             SUM(Mytable.Amount)
      From Mytable
      GROUP BY Mytable. Date, Mytable.Customer WITH ROLLUP)) AS temp

You need an aggregation. Does this do what you want?

select t.Date, t.Customer,
       sum(t.Amount) as Amount
from Mytable t
group by t.Date, t.Customer with rollup;

If you actually really do want the id, then:

select t.id, t.Date, t.Customer,
       sum(t.Amount) as Amount
from Mytable t
group by t.id, t.Date, t.Customer with rollup;
