I want to get (select) the next row value from MySql query using SQLYog, with the same id_voyage_order?
Example :
id_timesheet | id_voyage_order | Duration
----------------------------------------
1 | 106 | 0.00
2 | 106 | 24.00
3 | 210 | 12.00
4 | 106 | 12.00
5 | 210 | 24.00
i want to select it and make in View file Yii based on the same id_voyage order become like this and set the Duration of the last record become 0 :
id_timesheet | id_voyage_order | Duration
1. | 106 | 24.00
2. | 106 | 12.00
4. | 106 | 0.00
For instance:
SELECT a.id_timesheet
, a.id_voyage_order
, COALESCE(b.duration,0) duration
FROM my_table a
LEFT
JOIN
( SELECT x.*
, MAX(y.id_timesheet) previous
FROM my_table x
JOIN my_table y
ON y.id_voyage_order = x.id_voyage_order
AND y.id_timesheet < x.id_timesheet
GROUP
BY x.id_timesheet
) b
ON b.previous = a.id_timesheet
WHERE a.id_voyage_order = 106;
