Hi there,

I am looking for a code that combine the rows when end_date = start_date for a certain ID when all the variables have same values. For example, in the table below, ID 1 has 4 rows and their variables x and y have the same values in each rows under ID 1. ID 1 has end_date=start_date in each of its row. In that case, ID 1 will be combined into one row that will show the very first start_date and very last end_date.

id start_date end_date x y
1 10 12 10 12
1 12 14 10 12
1 14 16 10 12
1 16 21 10 12
2 11 13 15 17
2 13 15 15 17
3 16 18 20 22
3 18 20 20 22
3 20 25 20 22



Result will look like this:

id start_date end_date x y
1 10 21 10 12
2 11 15 15 17
3 16 25 20 22

I am seeking for help to get the code.
Thank you.

Kind regards,
Rakib
