更改查询中的WHERE部分,如下所示,它应该对您有用。

WHERE a.teknisi_ticket = '3603191601000002' 
AND a.status_ticket IN ('Approved','Progress')

请在下面的代码中尝试此操作

SELECT 
t.pc, 
t.trans_date, 
(
    SELECT SUM(x.sale) FROM tbl_sample x
    WHERE x.id <= MAX(t.id) AND t.pc = x.pc
    -- Just used MAX(t.id) in place of t.id
    -- As group by is available in the query
) - 
SUM(sale) AS accum_sales_beginning, 
SUM(sale),
(
    SELECT SUM(x.sale) FROM tbl_sample x
    WHERE t.pc = x.pc AND x.id <= MAX(t.id)
    -- Just used MAX(t.id) in place of t.id
    -- As group by is available in the query
) AS accum_sales_ending

FROM tbl_sample t
WHERE t.trans_date BETWEEN '2019-08-27' AND '2019-08-29'
      AND t.pc = 'p1'
GROUP BY t.pc,t.trans_date;
