Two short stays days apart in Thailand (British Passport)

I have a British Passport and I want to fly from HeHo (Myanmar) to Chiang Mai (Thailand), spend a few days there, fly to Luang Prebang (Laos), spend a four or so days there and then fly to Bangkok (Thailand) from Vientiane (Laos). When I arrive in Bangkok I will stay for four days before returning home on a flight.

Will I be okay with getting a Visa Waiver when I arrive each time, or should I do something in advance?

I did email the embassy but I got a canned reply that didnt quite provide the detail or the confidence I needed that all would be well.

splitting apart a mysql column with mutliple values. Not sure how to display

How would I make this dynamic?? for example -1 and -21 I have to change..
but in some columns I only have 11 or less.I am trying to display all the data between 'add to bob' AND '€' from one column. I tried searching for pivot table etc..

IMPORTANT >> I want each record for the column to display as a row..

I have tried functions and other stuff.. So far this is the best maunal way I can do it but in some cases
only a record of 11 may exist.. so I am thinking maybe some sort of left…
