hi
i have an error
Error: PL/SQL: ORA-00904: "GPS_TIMESTAMP": invalid identifier
as per the error number it referees to miss spelt column names
but in my table there is a colmn with name gps_timestamp
then what possibly is the error referring to
 
@user285oo6 add a question in the site, with your full code that produces this error.
gps_timestamp is not the same as "GPS_TIMESTAMP" by the way.
 
??
column names are dsiplayed in caps by default
in sql
 
It might be. But we can't see your code.
 
@ypercube is your crystal ball broken?
 
12:03 PM
@ypercube i hope the code is clear
 
@user285oo6 Then that table (or view, whatever it is) does not have a gps_timestamp column. As I said above, add a question at the site. Including the code and the table's definition (create table or create view).
 
k i will ask but i have the table created with restricted permission that's why i cannot post the table's defination
i can only post the screen shot of the defination
 
What do you mean? Can you not copy paste the code?
 
i will try please edit it if any mistakes are there

Q: Error in the procedure Invalid identifier is given,sql statement ignored

Of course I miss the point. Because your are not explaining anything.

@swasheck So, are you saying that the whole internet is wrong and should be terminated?.
Hey people, click here to see @swasheck say that internet is more dangerous than cancer
 
@Lamak that's my default mode
 
yeah, but that's no fun
 
but it's more realistic
 
3:29 PM
ok, you convinced me
 
that it's more realistic or that the information on the Internet is all wrong?
 
the realistic one. There's good information on the webz
 
No, "fast" is not ambiguous.
Fast can only mean one thing, regardless of your scale. "Faster" may be difficult for us to gauge, but it's still not ambiguous. Meanwhile, performant can mean a bunch of things, as can "more performant." — Aaron Bertrand ♦ 3 mins ago
 
@Lamak That was good information, for instance.
 
there's this chat, lots and lots of information
 
3:36 PM
@AaronBertrand Performant is a phrase thought up by someone who thought. Could I sound like more of an arrogant prig while speaking about performance?
 
Hi, @Zane. How's it going?
 
Pretty great how've you been?
 
I'm good. I'm going to Panama tomorrow

Q: SQL: Using outer join in SQL Server 2012

MikeI'm trying to learn how to use the OUTER JOIN function in SQL Server, so that the select query returns all values from two tables, even the unmatched ones. Here are the two sample tables I'm using (Boys and Girls): Boys: Name City Andrew Cape Town Mike Paphos Simon Amsterdam Girls:...

 
This is like 1984 all over again
 
@billinkc No, Zane and I didn't exist in 1984 ;-)
 
@billinkc party like it's 1985
 
@Zane what's wrong?
 
My client has an internal time entry system. That's not unheard of
What I do find ... unique is that they record time in increments of a day
Not hours mind you, just how much of the day did you do X
 
3:49 PM
" FROM boys, girls
RIGHT OUTER JOIN boys as men" Sounds like a bad SQL Server R and B band."
 
Spend your entire day doing something, you write 1D
 
@Zane well maybe they've never written sql before
 
Still funny.
 
agree, but at least they actually included a query they tried no matter how bad it was
that's a rarity
 
does there exist good documentation/whitepaper info on how CPU architecture affects SQL Server performance? i've been trawling berry's blog and have some good information, but was just wondering what else was out there
 
3:52 PM
@mmarie how long?
 
@swasheck he has some good ones on sqlperformance.com too. Although by "CPU architecture" do you mean x86 vs. x64 or do you mean generation / size / number of cores / clock speed or ...?
 
nehalem versus mmx
 
@swasheck Quantum processors or Biological?

@swasheck Zilog Z80 or Ricoh 2A03
 
4:15 PM
@AaronBertrand yeah. i've been reading through his stuff and most of his recommendations are for OLTP workloads. i guess i'm looking for what to look for in a CPU for data warehouses. my working theory is that i should sacrifice "performance" for "capacity" (in berry's parlance) to increase the potential MAXDOP for scans and such.
 
I'd say you should focus on number of cores and amount of memory. For DW you don't need blazing fast CPU speed.
 
i thought i'd referenced data warehousing in my original chat message but clearly i didnt. derp. i'm reading the FTDW.
@AaronBertrand right. that's the sense i got from berry's articles. Core count, chip cache, and memory. tune storage for best sequential reads.
 
Ideally you don't care about storage because you spent enough on memory
 
@AaronBertrand Agree the CPU we had at Wand was nothing special. It was all about the RAM.
 
@AaronBertrand ideally. sure. :)
 
4:21 PM
Right and I didn't mean you don't care about storage but you don't have to spend 99% of your money and time on the storage if you can get most or all of the data into memory
 
absolutely. i didnt take it that way. "all reads come from memory" so if you can get most/all of your reads to come from memory then that's the ideal.
 
@mmarie That is awesome.
@swasheck In a DW scenario I always notice the users almost all gravitate towards the same few sets of data anyway.
 
@Zane yeah. the most recent set (for us). that's a logical model change that we're recommending. we're also buying new hardware and we've been asked to make recommendations (this time, we weren't last time and it blew up on us)
 
There always seem to be a few stand out items that they go to over and over.
@swasheck I'd recommend upgrading from a Ricoh 2A03 to a Ricoh 5A22. Enter the blazing world of 16 bit!
 
Yeah so I'd say take most cores vs. fastest CPUs, maybe balance with cache (but I wouldn't go nuts about that), and spend the savings on more memory. Don't buy a server unless you stuff it with the largest amount of memory it will support. IMHO.
 
4:27 PM
Sorry I spent all Sunday playing and doing research on old game systems.
 
cool. thanks for the rec, @aaron. i suspected as much, but it's nice to have guidance from someone i trust more than myself :)
@Zane well - we're currently on AMD so you're not far off
 
Glenn has some specific recommendations but like you said he focuses on OLTP workloads (and it may be difficult to cross-ref that list with the supported CPUs for the motherboard in the server you need, which may be driven by other requirements such as U size, network, storage)
 
@swasheck lol.
 
@Zane I learned assembly on a Z80A
 
@swasheck oh yuck
 
4:29 PM
AMD was were it was at back in 2004.
AKA the last time I built a rig.
 
yeah. the per-core licensing penalty really kills you with amd
 
I didn't even trust it then. Maybe for a PC for my grandma
 
(we're going to 2014 with this as well)
 
@swasheck but there's a built-in AMD discount!
 
That original like of 64 Bit processors were sick nasty(how we talked back then).
 
4:30 PM
@AaronBertrand yeah. not worth it.
 
And my xp3200 that and my Radeon 9800 I could run some serious CoD 1 on that rig. :)
But oh the times have changed.
It's decided. I'm building a new PC.
I miss having one.
 
@James ... i found what appears to be the source of your vendor's recommendation - and it's not because of performance
> Logical File System: Mounting LUNs to mount-point folder paths in Windows, rather than drive letters, is preferred due to the number of volumes in many Fast Track systems.
 
I'm so over building PCs anymore.
 
@MikeFal I took about a 10 year break.
 
hi, i'm @MikeFal and i just purchase surface tablets on day 0
 
4:37 PM
Bah, day 30, please
@Zane I'm just tired of spending 8-10 hours trying to figure what I plugged in wrong.
And I don't game NEARLY as much as I used to. I gamed for 5 hours yesterday, which was the longest stretch of gaming time I had in about 4 months.
 
That's actually why I did consoles for about 10 years.
 
I'm just not a console gamer.
The only thing I played on console was HAlo.
 
The idea of working a 14 hour day at Wand and then come home to fix driver issues was sickening. However now the console market is really starting to feel like a rip off.
The a bunch of the games I've bought for my Xbox One have been rushed. Hell BF didn't work at all.
Destiny was all hype and no content.
 
Yeah, I've heard some poor things about Destiny, which is pretty disappointing considering it's from Bungie.
 
Do any of these games work like bowling on the Wii? (I feel so old all of a sudden)
 
4:48 PM
The content all got gutted for reasons unknown. Gameplay = great. Story = appallingly bad. Content = 4 hours worth.
 
Ummm....no
@Zane The main reason I play Bungie games is FOR the content. Damn shame if they took all that out.
 
Yeah their head writer quit like a year prior to the launch and they took out the entire story.
Now it's literally a fight between the good guys(light) and the bad guys(darkness).
All information about the world is given to you by telling you've unlocked a story card and to go to Bungie.net to read said card....
@AaronBertrand Shooter games.
 
@AaronBertrand tecmo super bowl FTW!
 
@swasheck Still the best sports game ever made.
@swasheck did you know this is a thing? tecmobowl.org/topic/…
 
i liked some of the old NES hockey games. eric lindros was badass. could score goals and destroy fools with massive checks. lemieux was still the scoring machine, but lindros was fun to play
@Zane didnt
but it's blocked

Tecmo 2015 Updated teams and Rosters.
You can even get it loaded onto a cartridge.

Oppy doesn't want you playing tecmobowl on company time!
 
i'm not that much into gaming right now
but ... it may be fun for a trip down memory lane
@MikeFal no doubt. they also dont want me to be productive either
 
Any good recomendations for an SSD?
 
I love Samsung 840 - I have two 1TBs in my Promise J4
 
5:09 PM
I don't know if I could do the TB as that would make it the most expensive part on my system.
 
You probably don't need the TB. I bought it because of $/GB, not because it was the biggest
I built a concatenated disk set - 2 x 1TB, plus a 512 and 256 I had laying around, nets me a 2.69 TB backup/archive drive, connected by Thunderbolt. I don't need to store anything locally anymore, so all my downloads, ISOs, VMs etc. go there.

Edited comment above
 
@ShawnMelton that's right
 
Ah, missed doing that last time...Thanks
 
6:17 PM
@swasheck Yes, that's part of why we originally started using mount points. I don't think it's the source of the SAP's consultant's misconception, though. He explicitly said that he thought using mount points improves performance. I'll try to ask him why he thinks that someday.
I guess it's possible that he read the Fast Track whitepaper and thought anything suggested in it must be fast -- is that what you're thinking?
The SAP consultants have also argued that they can't develop on Developer Edition, only Enterprise, and that log shipping is the only DR technology that works with SAP. I think they are more used to working with Oracle.
@swasheck It kind of loses at you 'write Javascript to query the database', doesn't it?
 
wired.com/2014/10/plantronics-backbeat-pro $50 is now considered less expensive
It was funny the contractor I worked for a bit with Army bought everyone the Boise headphones in an office that was "built" for collaboration (low wall cubicles)...I think that kind of defeated the purpose.
 
@ShawnMelton I recently got a pair of Sony MDR-10RBT - not quite as good as my wired QC-15s, but pretty darned close. And the number of times I've yanked the cord out (or someone next to me on the plane has)...
 
I never really like them, the high pitch frequency always gave me a headache if I wore them to long
 
Never had that problem. Usually only wear for an hour or two at a time - except on long flights overseas
(And I'm not brushing off the problem or suggesting it doesn't exist, just doesn't happen to me. :-)

Good luck finding one
 
@Zane OH.... hmmmm I'm free Nov 1 and 15 and Dec 6th and 13
Which reminds me I should probably book holiday flights to go see my family
 
My cousin and I are going to down there to scout it out. We'll see when works for us.

I undownvoted now, but one guy still used a shorthand

@MaxVernon yes, it is possible, and I don't think there is any auditing exposed to moderators (might take a ping to an employee). What was changed, exactly?
 
@AaronBertrand Actually, I thought there was a change, but realized now I'm just a dummy. Thanks for the answer, and your time.
 
7:16 PM
You should edit your profile to indicate you are in fact, a dummy

@billinkc SHUDDDDUP!
 
@MaxVernon Yeah I wouldn't really have believed it if you suggested that a moderator here changed your profile (or any site, really)
Don't even consider it. TVPs will outperform individual parameters and be much more scalable and flexible too (let's say you decide you want to support 100 parameters, then later change to 200, then pointy-haired boss wants 500 parameters - have fun maintaining that stored procedure definition). I really doubt the TVPs are the issue - this is like saying all the cars on the highway are slow, it must be the wheels - because they all have wheels! — Aaron Bertrand 55 secs ago

@PatrickHofman this is one of my all time greatest pet peeves. If you people don't like your answer they are free to downvote it for whatever reason they choose. It does not have to fit your or anyone else's standards. If someone feel shorthand is a good cause to DV then that's entirely their prerogative. Don't tell me how to use my vote. P.S. I didn't downvote but you should totes not use shorthand it's needless and confusing. — Zane 1 min ago
 
Did you just use "totes"?
 
Indeed. I don't know why but I thought it would be funny.l
 
@ShawnMelton I addressed that in my answer and got a little more direct about it in the comments

7:39 PM
Wasn't my down-vote either, but seriously, your initial error was wrong because you were using lazy shorthand, someone suggested an edit and you changed mm to mi instead of actually fixing it? Write your own code however you want, but I am opposed to promoting lazy shorthand that leads to the same problem that made your initial answer wrong in the first place. See #6 here blogs.sqlsentry.com/aaronbertrand/… and sqlblog.com/blogs/aaron_bertrand/archive/2011/09/20/…Aaron Bertrand 17 secs ago
 
I think I've seen a question with a query with ambiguous results but I can't remember it. It must have been long time ago.
I think it was more complicated than your example, and had three tables so it could be seen as either `(a LEFT JOIN b) JOIN c` or `a LEFT JOIN (b JOIN c)`
@AaronBertrand "your initial error was wrong" ?
 
@AaronBertrand Why do people get so pissy about loosed 2 magical unicorn points?

I don't think he is that pissed. He is just lazy - to edit the answer.

@Lamak Yeah, that's my point. He only edited 1 character.
 
always entertaining when The Heap™ gets on a comment thread

@Lamak that's the part that bugged me.
 
@AaronBertrand yeah, it's kinda bizarre, moreso taking into account that using a shorthand led him to an error in the first place
 
Yeah "learn from your mistakes" comes to mind

@billinkc I like to use "cubic hectare"
 
So, apparently "moreso" is an incorrect (but sometimes used) way of writing "more so". Didn't know that
 
@Zane I like it moreso because there is a greek word that sounds the same - and is also not a proper word.
 
I'll make the ask of Oxford to include it in their next edition
 
Yes, please doso
 
that ask better be made most performantly

You mean for a free MSDN subscription? Or a promo code for a discount?
 
for a discount
 
We used to get the former as MVPs - three a year, IIRC. I think they canned it because the Subscription IDs were appearing on eBay or similar.
