Do the Number of Columns "Slow Down" the Time Required for SQL Joins?

2021.12.03 00:33 SQL_beginner Do the Number of Columns "Slow Down" the Time Required for SQL Joins?

I am running the following SQL query using the R programming language to perform an inner join:

table_1 = data.frame(id = c("123", "123", "125", "125"), id2 = c("11", "12", "14", "13"), date_1 = c("2010-01-31","2010-01-31", "2015-01-31", "2018-01-31" )) table_1$id = as.factor(table_1$id) table_1$id2 = as.factor(table_1$id2) table_1$date_1 = as.factor(table_1$date_1) table_2 = data.frame(id = c("123", "123", "125", "125"), id2 = c("111", "112", "14", "113"), date_2 = c("2009-01-31","2010-01-31", "2010-01-31", "2010-01-31" ), date_3 = c("2011-01-31","2010-01-31", "2020-01-31", "2020-01-31" )) table_2$id = as.factor(table_2$id) table_2$id2 = as.factor(table_2$id2) table_2$date_2 = as.factor(table_2$date_2) table_2$date_3 = as.factor(table_2$date_3) #SQL library(sqldf) sqldf("select distinct * from table_1 a inner join table_2 b on (a.date_1 between b.date_2 and b.date_3) and a.id = b.id or (a.id2 = b.id2)") 
My Question: In my actual data, "table_1" and "table_2" contain around 20 columns each - however, most of these columns are not required for the "join". If I include all these columns (e.g. select * from table_1 vs. select id, date_1 from table_1) - can this make the "join" take a longer amount of time? Or does the computer ignore the other columns not required in the "join" and simply take the same amount of time whether all columns are included vs. only the required columns?

Thanks!

2021.12.03 00:33 ElasticFish12 27/F Looking for long term friends to chat/game with!

Hello! I’m 27 and from Canada. I’m hoping to meet a few people to chat with and maybe eventually play some games. Some of my hobbies are fishkeeping which is probably my biggest hobby, I have four tanks and I’m hoping to upgrade soon! I also love Magic the Gathering and have been playing for around 18 years, I mostly play commander nowadays. I love gaming too, Monster Hunter Rise, Monster Hunter Stories 2, Fallout 3, Fallout 4, Fallout New Vegas, Morrowind, Oblivion, Skyrim, A bunch of The Legend of Zelda games, Pokémon, and Heroes of Might and Magic 3 are some of my favourites but I enjoy more as well! As for work I’m currently a supervisor of a cafe, not enjoying it too much but it pays the bills lol. I’d love to chat about anything!

One of our main priorities is making our token safe, fair and completely transparent for all investors. Thats why we have renounced ownership of the Shiba Max contract on launch ensuring no individual or entity has control of Shiba Max, ensuring that it is decentralized and secure for all investors.
Our Tokenomics are as follows:
Auto-Liquidity Generation: 7% of all Shiba Max transactions will be contributed to building Liquidity ensuring the growth, stability, and sustainability of the token. This feature ensures that the price of the token is backed by a constantly growing liquidity pool. Multiple secure liquidity pools will be added as we grow, and our token is listed on centralized exchanges such as Bilaxy and Hotbit. The rate of contributions will only increase as our community grows and trading volume increases providing stability and security to our investors.
Decentralization: Contract Ownership was renounced at launch as a result of this action no individual or entity has ownership of the contract, making Shiba Max secure and fair for our community and truly decentralized. 100% of Liquidity was locked on launch (Please refer to our FAQ section for link) to ensure security and peace of mind for our investors.Shiba Max was tested extensively using the testnet prior to launch to ensure absolute security and accuracy of function, it was designed to be scalable, self-sustaining, and to scale seamlessly and frictionlessly on a fully autonomous and rapidly growing DeFi ecosystem.
Shiba Maximum Rewards: All holders will have their Shiba Max balance grow through RFI Rewards at intervals as the Shiba Max Army grows. This function will allow the Army to effectively earn interest rewards which will increase as our community grows. Our mission is to ensure that the Shiba Max Army is rewarded as our domination of the Crypto Market continues on.
The Shiba Max NFT Marketplace and its offerings is brimming on the horizon. We will be working garner a roster of the best Digital artists, Influencers, Celebrities, and Athletes to have an all-star lineup of NFT releases at launch. The Dynamic NFT releases would also be paired with Physical Merchandise to add further value to our Marketplace offerings. Airdrops will also be going out to our top shillers and holders.

2021.12.03 00:33 ForgottenZodiac 29 [M4F] Pennsylvania/USA/Anywhere, Looking for endless conversations and someone to call mine

Hello, I am 29, 5’11 and average build. I am 100% Italian and naturally tan. I own a house and have a steady job.
I enjoy camping, cooking and watching movies. With the pandemic I find myself being more of a homebody.
What I’m looking for, I’m open to all little bit of everything honestly. Getting along and having a connection is what matters most to me. I’d prefer 21-32 but am open to it as long as we connect.
I don’t want to rush into anything friends first and let something evolve naturally. Think it’s the best way to go about doing this.
I am big on cuddling and have been told I give great massages. So that could be something to look forward to?
If you made it this far thank you for taking the time and reading it! If you message me include your favorite flower or color, maybe both!

2021.12.03 00:33 PatriaBeckert POMPA ($PMP) - Just launched and it's pumping. 💎 x100 potential 💎

POMPA

Had enough of rugs? Had enough of coins that promise to give you insane gains only to be left hanging with a heavy bag of practically useless tokens? Aren’t we all 😆. Well then you must have a horseshoe up your ass cause I have the one coin that will actually give you the crazy 10X 20X 30X or even more which other coins always promise but ultimately fail to deliver. 😤

What is POMPA ($PMP)?
$PMP is a frictionless yield generating protocol. All you have to do is HODL.

The holders are automatically rewarded more $PMP by holding. This is done by charging a 5% tax on all transactions, which are then split 3% to all holders as rewards, and 2% automatically added to the liquidity pool, creating price support and stability.

SAFU?
$PMP is completely safe. There is no proxy in the contract and it’s not pausable. Ownership is also renounced and liquidity is locked.

2021.12.03 00:33 OkJaguar6479 I want to get into the Legend of Zelda game :)

I’ve recently wanted to start playing Legend of Zelda but i’m not sure what to start on, I’m not sure where it’s available but i’d prefer to use it on a Nintendo DS. I’m completely set on that but i’m not sure what version to get, i already own a Nintendo 3DS and could most likely “borrow” my moms old 2DS so i’m pretty set on one or the other. I’m not a huge video game person, although I’d like to be, my experience with video games is pretty much limited to Monkey Ball Banana Blitz on Wii and Minecraft. Which is why I need help because i have no clue what version of the game to get and i just wanna know what would be the best thing to go for. I just want the little chip to stick inside one of my DS’s idk how well i explained my situation but if anyone can help I’d be super grateful.

2021.12.03 00:33 ClownBabyBrandon22 Lolita Express aka Epstein’s plane

I heard Epstein’s plane is named Lolita Express. Its interesting how they named their private jet after a Stanley Kubrick film. In 1999 he made Eyes Wide Shut effectively exposing and revealing the dark underbelly of our society through the depiction of the discovery of a sex trafficking cult. Thats ironic and/or creepy right?

What separates Verify from the rest of the crypto projects that are currently launching? A unique and needed use case. Verify Lens is not a gimmick and it will help each and every investor in various ways!
Let me introduce you to the ICO of 2021, VerifyToken! You’re probably wondering what makes Verify different than all of these other shilled posts, so allow me explain.
Cryptocurrency crimes rose by 1,000% in the last year alone! According to the FTC, consumers lost at least 80 million dollars as a result. Guess who the consumers are…us. And, nobody is stepping up to protect ‘us’ so there is a clear need for what Verify is doing!
Verify is bringing full transparency to the crypto market. The utility behind Verify is Verify Lens. It is a cloud-based dashboard that will gather data on defi projects—new and old—to aid the investor in making a more informed decision. The dashboard is currently under development. We will be using our own API’s to communicate with API's from multiple sources to answer your typical DYOR questions. On top of that, users will be able to check audits and doxxed devs, label wallets, track wallet movements, and get a security rating for any project—and more! Our algorithms will create confidence scores for every project so you can make more informed investment decisions. With so many people being scammed daily in BSC (some of us included), we believe this will be a powerful tool to educate investors and deter scammers.
Doesn’t that sound like a much-needed service? And you can get in on it early! Join our Telegram to get the details about how you can purchase!!!!
At this point, you probably want to head over to our website to learn more about Verify Lens and see our timeline—hope to see you soon!

2021.12.03 00:33 FinanciallyAddicted Are American Employers giving more Workload

So I work for an American company offshore and what really came to my attention was the work that was given to other employees. It seemed like they would actually have to work hard to complete it in a work day.
The tasks that are setup sound like we have a lot of work on our hands.
So is it like true that the workload has increased compared to like 5 years ago. I read some confession post where the guy was happy with his job but had to work from 9-7:30.
