Comments:
<0> dan__t: Use a loop in your script language, use while or foreach if using PHP <1> anyone have experience with xcart and tuning it's database? <2> there are some prewritten perl scripts that do a very good job <2> ability to specify multiple simultaneous connections, etc <3> benchmark(count, expression) Evaluates expression count times. Always returns zero - the point of this function is to time execution and look at the execution time at the bottom fo the result <2> expression <2> not query <3> I must not recognize the difference <3> Care to clue me in? <0> I think thats general script difference <2> an expression is a small part of a query <0> Look up what an expression is <2> "'true' = 'false'" is an expression <2> datediff(NOW(),NOW() - interval 1 day) is an expression <3> ok, sorry. <0> looks like your using perl but php.net has a good explanation of what an expression is
<2> he's talking in the context of mysql <2> he's talking about mysql's benchmark() function <0> oh, i've never heard of it, sorry <3> rad. <0> is there a linux shell chatroom on this server? <4> "chatroom" ? <0> IRC room <4> you mean "channel" on IRC <4> try #bash <0> what would you call SSH and telnet <4> bash = Bourne-Again SHell <0> bash or shell? <4> neither <0> whats the difference? <4> I call them remote terminal protocols <4> remote consoles <0> wise guy huh? <4> but if you mean the actual command line <4> that's usually bash <0> alrighty <4> not a "wise guy" at all. <4> if you don't say what you mean, nobody can help you. <0> im trying to figure out what im supposed to mean <4> so, is it the command shell you want help with ? <4> or getting access to one ? <0> and im pretty sure you knew i meant the command line <0> i got my protocol working fine, just i seem to newb out with some of the bash commands <4> look man, I can just put you on ignore if you keep that up <5> grml <4> ok, well #bash is the channel specializing in the shell scripting language <0> thank yo <4> at least here on freenode <0> free node has the best computer related support i've found <5> this damn print job... i hate design >;/ <5> crap has to be at print @ 8 am... <4> Clownboy: no disagreement with that <2> i'm an efnet kind of guy <2> the abuse is the best part <0> efnet isn't bad <2> you have to be ok with the abuse :) <2> but i've been on efnet for, uh, 13 years <2> so the abuse is ok. <0> Ok, mysql question, would you reccomend using backticks or not? to me it helps mysql in the long run, but i've been told not to use them.... <2> i'd advise against it in general, simply because it keeps you from using reserved words <1> anyone have experience tuning xcart? <0> (SELECT `col` FROM `table` WHERE 1) <2> that is, people can go around creating tables named "where" willy nilly if they used backticks, and then user b comes in to try to maintain the code and gets screwed when he doesn't use 'em :) <1> Clownboy: you will only "need" them when using table names that conflict with reserved words. <2> column names, db names as well <0> But does it really hurt to use them? <1> no. <2> for the reasons i mentioned, sure :) <0> Well I rarley code with another person <2> so? <2> you might <2> someone might have to maintain code at some point <0> and I've got the brain not to use reserve words <2> then why bother using backticks? <6> sometimes it causes problem when you upgrade and there are new reserved words that you did not quote previously, so used unlikely reserved words
<2> well yes <2> although ***orted practices help with that <0> my brain likes it better, my brain parses(reads) the code better, dunno, just a preference <2> there are very few reserved words with _s in them and those are pretty easy to predict <6> try to used identifier that is not likely to become a reserved word <0> Anyways, backticks are playing it safe right? That's how I play <1> gleam_: you can get into a situation when you write scripts to deal with table/db names that you didn't control or you wont know what the name will be. It is alot safer to use them. <0> la <0> Sorry, meant to type ls in putty, and it came out la in IRC, LOL <2> i'm not saying you should never use them, i'm just saying you shouldn't use them unless you need to <2> and you rarely need to <2> this is all personal preference anyway <0> And your reasoning for that is that it might encourage me to use reserved words as cols and tables, correct? <2> and that i don't like the way it looks :) <0> TodoInT1: Good point <0> I think it looks better :) So pretty much is boils down to opinion <2> (cdt) <0> yeah figured that out arleady <3> Has anyone written a super duper InnoDB preformance document yet? <7> evening <3> hi. <3> I want to squeeze as much as I can out of this. <7> is there a way I can get the total number of rows in a database out, and still do a LIMIT x,y ? or do I need 2 queries <3> SELECT COUNT(*) FROM table WHERE ... ... <6> TheDeathArt: SQL_CALC_FOUND_ROWS and FOUND_ROWS() <7> yeah, but dan__t that would only return the rows in the limited result, wouldn't it ? <7> ahh, SQL_CALC_FOUND_ROWS :) thanks <3> ahh <7> lokus do I need both in the query ? <6> !m TheDeathArt select <8> TheDeathArt: (SELECT Syntax) : http://dev.mysql.com/doc/mysql/en/SELECT.html <9> !m random <8> Incorrect usage. See 'help m' <7> yeah, im looking at it <9> Hmm <7> but can't figure out how to use it, since it returns 0 <7> a sec, and i'll slow the query <9> Then: does anyone know of a way to return rows in random order? <6> TheDeathArt: called select found_rows() to get the number <7> http://phpfi.com/119479 <10> !tell us about random <8> infi asked me to tell you this: For information on selecting random values see http://jan.kneschke.de/projects/mysql/order-by-rand/ <9> Ah <7> that current query returns the data correct, but the "totalrows" is 0 <7> confuses me a bit <11> Anyone know why in phpmyadmin I change a type to char(32) and it says the sql query was exec'd, but it still shows as varchar(32)? http://hashmysql.org/paste/viewentry.php?id=1888 <7> is it not possible to use SQL_CALC_FOUND_ROWS and FOUND_ROWS() in the same query ? currently I can only see the manual does it in 2 <2> no, and who cares? <2> what's wrong with two queries? <7> well.. the idea using it was to avoid 2 queries :) <2> this isn't really two queries <6> anyway the 2nd query just read the value off a counter <6> no table access <2> yeah <2> doesn't have any impact on anything <2> kind of like last_insert_id() <7> mm, but just read it don't work for LIMIT x,y , only for LIMIT x <6> no reason it won;t work <7> well, comments says it don't return all rows then <2> probably returns foundrows-x <7> http://dev.mysql.com/doc/refman/4.1/en/information-functions.html , 3rd last comment <2> try it and see <2> actually it returns same # regardless of limit x,y or limit x <2> (just tested) <7> okay <2> easy enough to test for yourself, of course. <7> ye doing, except asp.net can't just do a quicky query, hehe <2> that's what the command line interface is for. <6> that comment did not use the correct syntax anyway <2> yeah really <2> and the comment above it explains that <6> TheDeathArt: always have mysql CLI for testing purpose <2> totally.
