公司一段 SQL 是這樣寫的:
select top 1 t2.xxx
from (
巴拉巴拉一大串,看到眼花
) t1
left outer join t2
on t1.xx = t2.xx
where t2.xx = XXX
所以我說,前輩中間寫那一大串是在裝忙嗎?
select top 1 t2.xx
from t2
where t2.xx = XXX
結果一模一樣 @@
最近大前輩一直抱怨公司資料庫效能太差,我彷彿知道了什麼

As this will be the last week for you to register the Coway Run, we’re giving away 10 free tickets, WOHOO! Just tell me where’s the location of Coway Run and booomm you will win the tickets. Its that simple!
Just as a fellow runner myself, here are my favorite and the best places to run!
1. Lembah Kiara Park:
Level: Beginner to Intermediate
- If you want to do some regular running. I would say this place is a good start. The distance of the standard loop is about 1.1km and they are mostly flat! Well, this place isn't just full flat, you can opt for a more challenging route by taking the outer loops.
2. Bukit Kiara:
Level: Intermediate to Advanced
- Seriously, this place is one of my favourite spot! If you are ready to hit the hills hard for some intensive hilly conditioning, this place is for you. If you want to try trail running, you can try going off-piste! However, if you do so you must run at your own risk, and make sure you do it early of the day.
3. Desa Park City
Level: Beginner to Intermediate
- For those who love running at night. I would say Desa Park City is probably one of the best and the safest place for late evening run. Well, other times are actually great too... Some of you might have seen me here quite often, because this is somewhere convenient for me to train.
So where is the best place you should train? Well, it doesn't really matter where, as long as you are able to train consistent at places that is convenient and safe for you!
Now, we have only 2 weeks left to the Coway Run! If anyone wants to join me in the run, here's your last chance before the registration close. Hurry! www.cowayrun.com.my

The Outwer Worlds
ซื้อเกมได้ที่ https://store.epicgames.com/legendauser/the-outer-worlds
The Outer Worlds is a new single-player first-person sci-fi RPG from Obsidian Entertainment and Private Division.
Lost in transit while on a colonist ship bound for the furthest edge of the galaxy, you awake decades later only to find yourself in the midst of a deep conspiracy threatening to destroy the Halcyon colony. As you explore the furthest reaches of space and encounter various factions, all vying for power, the character you decide to become will determine how this player-driven story unfolds. In the corporate equation for the colony, you are the unplanned variable.
• The player-driven story RPG: In keeping with the Obsidian tradition, how you approach The Outer Worlds is up to you. Your choices affect not only the way the story develops; but your character build, companion stories, and end game scenarios.
• You can be flawed, in a good way: New to The Outer Worlds is the idea of flaws. A compelling hero is made by the flaws they carry with them. While playing The Outer Worlds, the game tracks your experience to find what you aren't particularly good at. Keep getting attacked by Raptidons? Taking the Raptiphobia flaw gives you a debuff when confronting the vicious creatures, but rewards you with an additional character perk immediately. This optional approach to the game helps you build the character you want while exploring Halcyon.
• Lead your companions: During your journey through the furthest colony, you will meet a host of characters who will want to join your crew. Armed with unique abilities, these companions all have their own missions, motivations, and ideals. It's up to you to help them achieve their goals, or turn them to your own ends.
• Explore the corporate colony: Halcyon is a colony at the edge of the galaxy owned and operated by a corporate board. They control everything... except for the alien monsters left behind when the terraforming of the colony’s two planets didn’t exactly go according to plan. Find your ship, build your crew, and explore the settlements, space stations, and other intriguing locations throughout Halcyon.
