Hello.
My father was born in Hrebeniv, but left for Canada as a young adult.
I know he would love to see any pictures for his home town.
Any photos that you could offer would be appreciated.

Thanks.

I get an error when running your code on MySQL 5.0.51

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'varchar(64) as
return @book_subject' at line 2

or instead of turning off such a useful feature, in rare scenario of creating an xml template where php naggingly turns on, you could simply echo out the xml definition before closing your php tags as such.

echo'' ."\n"

Re: STL sort strangeness

Although Fisher-Yates shuffle (unlike the one above) is evenly distributed in theory, its rand()-based implementation will still have a small deviation from the uniform distribution due to the modulo bias (small numbers will have higher probabilities).

If it works for your application that's fine, but your shuffle algorithm will have non-uniform distribution. Look up the Fisher-Yates shuffle, which is about as simple and almost certainly what std::random_shuffle uses.

stick,

no doubt the problem arised on a plain surface, but hopefully this post will save those many hours for someone who reads it. ;)

Rexxar,

didn't know about that one -- thanks for pointing out.

Why you don't you use "std::random_shuffle" defined in ?

Wow it seems like an incredible amount of energy went into something as absolutely braindead as shuffling the elements of an array.

Perhaps if you had used an array instead of relying on some esoteric use of the stl you could have saved yourself and all your readers many HOURS of time.

Live and learn. Have fun blogging instead of writing working code.

Re: MySQL views gotcha

Olexandr Melnyk — Sat, 22 Dec 2007 08:21:52 -0000

Hello Brik,

Seems I also want to update my view(s) with a trigger if an underlying table changes!

MySQL doesn't support schema-level triggers, so you'll have to handle that in your application.

Any examples for me? One example of a trigger that creates a view, using a fieldname as the viewname and also a fieldname in the where clause for the view? TIA.

I don't understand this part, could you elaborate on that?

How about a trigger that keeps track and updates all views? (I need that less)

When you change data in a table, a related view gets automatically updated. Please, read my post again carefully: view doesn't get updated on table structure changes.

Brik — Wed, 19 Dec 2007 16:50:29 -0000

WOW - I did not know that!!! I was about to mess up a bunch of stuff!

I am sort of new to mySQL and my DB experience is pretty slim in general. I am forced to work on a data collection app... long story.

Anyway - I have been researching how to create views with database triggers. Seems I also want to update my view(s) with a trigger if an underlying table changes!

Re: Local .NET conference

Sorry, if I was unclear in my explanations. Npgsql has a different purpose than plMono. Npgsql allows you to access PostgreSQL from your .NET application, while plMono was intended to provide you with the ability to extend PostgreSQL using Mono (write own stored procedures, triggers etc), like you can do with PL/Perl and plpython.
