    Nothing at all amazing about horribly inefficient joins. Anyone can (and often does) do that. The only WTF here is that the "consultants" were believed without question for so long... I mean, was there really nobody with any experience at all who'd look at the DB size and  say "hey, the reports can't be that complex!"

  • Curious George (unregistered)

    The real WTF here (tm) is that they didn't add more RAM to the system.  Surely every IT guy/gal knows that a reporting engine needs a lot of RAM.

    Or, if you want to be picky, you could optimize the query to do "{START_DATE}' OR {FIELD_NAME} BETWEEN '{START_DATE}' AND '{END_DATE} WHERE {FIELD_NAME} LIKE "%Paula%" OR {START_DATE} LIKE '%Brillant%'.

  • dasmb (unregistered) in reply to ChiefCrazyTalk

    No, it's because to be a successful consultant you only need to be smarter than your smartest client.  Find a dumb guy who's got good sales and you can suck at his teet for a while.  And this stupidity is bolstered by proper misinformation.  I'll bet this relationship could have continued onward to big iron and week-long batches if Adam hadn't gone and screwed it up.

    The irony here is that the consultant who fucks things up and gets paid to come back, multiple times, to fix it at high rates, will inevitably be more successful than one who does it right the first time for cheap.

    Last place I worked we had a bunch of servers set up by "guys across the hall" who had their own IT consultancy (we were a software firm).  Their hard work presented us with a) A broken active directory, web and file server b) A seperate mail server, running a beta version of Exchange that ran out (!) while I was working there c) A Novell Netware server, whose sole task was acting as a summarily crappy firewall that left the development server in a "DMZ" d) a tape drive, complete with backup software, that close as we could tell never once backed up anything properly, ever, but was programmed to spit out its tape every morning.

    None of these machines had any virus protection, so all of them had viruses.

    The only consolation was that we very rarely paid them.

    Not a big WTF here, but you would think that the consultants would at *least* go back and check their query to see if they could speed it up rather than suggesting going to a report server, and then to an over night cron....but maybe that's why I'm not a highly paid consultant.

    That's also assuming that the consultants can write basic SQL and recognize that they incorrectly joined a few tables.

  • (cs) in reply to rbriem

    This should be an effing axiom.

    "If your row count is best represented in scientific notation, you should probably recheck your design."

    Even in a situation where you have hundreds of thousands of transactions coming in a day, you need to do the reports, and move on. I worked in a system were we got more than a million data inputs a day in a single table. The solution was to make a new table for every days transactions, and as the tables aged we'd consolidate them into summaries, and remove the originals to hard storage. Smooth as clockwork. Reports never took more than a half an hour to run except at end of year closing, where we had to run a year-end summary, and that barely took an hour.

    Another possibility is that the query accidentally had a cartesian product which was being masked by a union statement. Such errors are very easy to make and would not have been easily noticed in early testing phases. Making such errors is quite understandable and hardly constitutes a WTF. Being unable to find and correct such errors, however, is another matter entirely.

    What always makes me nervous is finding a query written by someone else that contains unions and distinct. I start reasoning as follows: either the union / distinct is masking duplicates or it is not. If it is not, I should switch to union all / remove distinct to improve performance. If it is, I should switch and fix to improve performance. Therefore, I should switch to improve performance. Then another part of my brain kicks in and says "dont fix it if it aint broke".

    Indeed. My rule of thumb is if I find myself using DISTINC or UNION (not ALL), I'm probably doing something wrong, and should re-think my where clause.

    By the way, Sybase really needs the SQLServer "join" syntax so where clauses can be less WTF-ery in and of themselves.

    Maybe the consultants were on a fixed bid contract and would not get paid for fixing their queries. On a fixed bid contract, your solution to every performance problem is telling the client to buy more hardware or run the job less often. I charge/get paid hourly so my solution to every database performance problem is looking at my queries, staring at the explain plan, and fiddling around till it runs faster. Clients may prefer fixed bid for many reasons though.

    I think the bit about the fancy pants consultants comes from the expectation (created by the sales department) that Consultants with high charge out rates will be creating better code than low paid employees. Salesmen often overpromise in order to close a deal. I like to underpromise and overdeliver if I cannot give a good estimate (like Scotty from Star Trek) which is why I'll never be make it as a salesman.

    Well, I worked as internal "IT manager" (that meaned "Everyone's slave") and programmer in a place where day after day after day external programmers came to "refine" the "exceptional do-it-all make-a-coffee" management program. Well, consider that it manage ANY aspect of the factory, from bookeeping to production. The server had Win2003 and MySQL.

    This just to make you aware of the critical level of this "wonder".....

    The wonder wich I'm talking of (it's an industrial application, not an "ad-hoc" solution) had an internal scripting language very similar to basic (and to this point it could also be ok) with "advanced" features to access  databases and modify the native interface of the program.
    Some features of this beautiful scripting thing:
    - NO functions, only labels, goto and gosub;
    - multi-dimensional arrays limited to 3 dimensions;
    - an array could had up to 64000 values - IN TOTAL!!! So, you couldn't have had arr(100,100,10);
    - no variable types - just numbers (var) and strings (var$);
    - proprietary developement environment, 72 cols * 19 rows (no kidding). A single row could have been long up to 400 chars, if i remember well. I finished my right and left cursor keys;
    - copy/CTRL-C and paste/CTRL-V? Are you kidding? I don't remember well, but F3 starts block/F5 ends block/F7 paste;
    - and, just to make everyone happy, ALL CODE IN CAPITAL LETTERS.

    This should have introduced you to the horror.....

    When you add to this gems like:

    ANGSUPSIN$ = "|"
    RIGSUP$="-"
    ANGSUPDES$="|"
    PRINT ANGSUPSIN$+RIGSUP$+RIGSUP$+RIGSUP$+RIGSUP$+ANGSUPDES$

    and so on to make a rectangle (substitute |- with graphical symbols), you begin to get the keep of it.

    Some exaples of variables the consultant geniuses used in nearly every program:
    A$
    XA$
    XXXA$
    XXAXX$
    Naturally, without any comment.

    I'll post later some other examples....

    Yes!  that is a great rule of thumb.  Too many people just add "DISTINCT" to the beginning of a SELECT because the results have duplicates to "fix" it.  And 9 times out a 10 a UNION should be a UNION ALL (which is also much more efficient).

    That's ANSI join syntax, not SQL Server, by the way.

    I think I need full outer joins about once per project. Unfortunately, one of those projects was on Oracle 8i. I was young and naive and thought that putting the + sign on both sides of the equls sign would do the trick - ah the bliss of ignorance. I felt so dirty doing a left join and union alling with a right join and copy-pasting the query text. Each time I had to modify the query, I had to change the same crap in two places. Cringe.

    I remember asking about upgrading to Oracle 9 which supported full joins and the ansi syntax. Then I learned that they would have to upgrade their unix operating systems to support Oracle 9. Then I learned that there were lots of other older apps running on the same server and that upgrading the OS could make the older apps blow up. Then I learned that upgrading the OS on the test server would be bad because then other apps on other production servers would become out of sync with "the test server". Yup, that's right, there were multiple independent applications on separate production servers all sharing the same test server. Double Cringe. I wonder if this setup counts as a WTF.

    FULL OUTER JOINS should never be used, or for that matter, RIGHT OUTER JOINS.  If you think you need a full outer join, then you are doing something wrong.  Any JOIN that potentially returns a null in *every* column, including all key columns (albeit on different rows), is a complete mess.   You literally must wrap every column with a COALESCE() function, and any further processing of those results cannot use any indexes since all columns are now wrapped in functions.

    Often, a UNION or a clever CROSS JOIN is all that you need to generate the resultset that you *think* might require an ugly FULL OUTER JOIN. 

    RIGHT OUTER JOINS should *always* be written a LEFT joins.  no exceptions there, either.

    Asking a candidate when to use about FULL OUTER or RIGHT joins is a great interview question; you can immediately tell if they are book smart and just memorized definitions, or if they have actual skill and experience with SQL.

    Got a problem with something being slow?  Throw more hardware at it!


    The thought of throwing hardware at the consultants is an attractive one.

    And don't bother to hire more sysadmins to manage it all... they're expensive just slack anyway.

    No, I'm not THAT bitter.  Really.


    One municipality could not find it in their budget to have a full-time IT person.  They ended having to use a local company for network support.  I do not know the dollar amounts involved, but it would not have taken much to equal a full-time salary, and they would have had a person available for many more hours.  Penny proud, pound (and just plain) foolish.

    Sincerely,

    Gene Wirchenko

    FULL OUTER JOINS should never be used, or for that matter, RIGHT OUTER JOINS.  If you think you need a full outer join, then you are doing something wrong.


    Pshaw.


    Disagree?  Do you have an example?

    Disclaimer: I started out my career as a professional software developer (trained in Computer Science) with eight years of (successful) experience. I have since moved into a consulting firm.

    The reality of consulting firms is that knowing how to run a query analyzer and interpret the results (or horrors, look at the query itself) isn't the kind of skill that's going to justify the margins that they need to pay their bills. These days, moving deep technical work to offshore labor for is a big part of how consulting firms compete on price. (Considering that consultancies drive a lot of offshoring, it's natural that they do it themselves.)

    The same thing goes for consulting firm employees: technical work doesn't pay the bills where they work, so it doesn't help people succeed in the hierarchy (which is very strong in consultancies). The ability to interview a client team, understand their business process,  and work with them to write a 100 page specifcation for a business application is going to be far more useful than the ability to actually code the app. (which will probably be done in India.). While this typically implies that the on the ground technical skills of your consultants aren't what you'd like, aren't you glad your company isn't paying $200/hour for a SQL skills? (I haven't worked with anybody where I work now that I'd trust with a copy of Eclpse or even Visual Basic)

    (Of course, if your management is expecting coding miracles (or even adequacy) out of $200/hour consultants, then you're f***ed anyway... and for reasons likely to be more significant than most of the code shown on this website).
