16 rows in set (0.00 sec)
In the above chart, I need to select 2 seats those are in the same row AND column numbers are next to each other.
For e.g. Seat Numbers 38 & 39 can not be issued even if both the seats are from the same row because the column numbers 2 & 5 are not adjacent.
The expected results are as follows:
31
33
35
37
39
41
43
These are the starting numbers and the next seat will be automatically booked as well. for e.g. 31 & 32
