Yeah, and funny enough, it's still "to be" included in the next version of MySQL ... and what they have so far for 4.1 (in the 4.1.1 Alpha) is one implementation of subselects for the FROM clause and apparently another one for the WHERE clase (this is an assumption based on the fact that subselects support different language features if they are in the FROM clause or the WHERE clause). Fortunately I don't have to maintain any of that code.

While feature comparisons may work with people migrating from commercial RDBMSs, as they'll consider the feature/price ratio, this does not quite work with MySQL crowd. I was recently giving a small presentation on PostgreSQL on a Russian PHP conference and found out an interesting thing: no one there really cared about feature comparisons. I did a table with PostgreSQL features and the versions they appeared in. This did not go completely unnoticed, as the next lecture was about the new features of MySQL 4.1/5.0, but the people were not really interested and didn't ask questions. What's more interesting, no one really cared about PL/PHP as well. The meta-questions asked were: 1) The main *drawbacks* of PostgreSQL; 2) When does one need to use PostgreSQL; 3) The performance question. As the PostgreSQL advocacy group thinks that PHP programmers are among their *main* target audience, may I humbly suggest answering the questions that are asked instead of the ones that are not? The most successful (most quoted) advocacy articles I remember were the once from OpenACS (Why not MySQL?) and sql-info.de (MySQL gotchas). To make people look at PostgreSQL you should concentrate on why MySQL is *bad*, to create a sense of insecurity in its users. That is the propaganda that works.
Alexey, First off, I'm glad you posted this. Our advocacy thinking tends to be heavily US-dominated and I've wondered for a while how things are in your part of the world. > I was recently giving a small presentation on PostgreSQL on a Russian > PHP conference and found out an interesting thing: no one there really > cared about feature comparisons.

Clayton Christensen has a facinating book called "The Inventor's Dillemma" about how business forces inevitably push companies to over-feature their own customer base. Certainly both MySQL and PostgreSQL already have more features than 85% of the PHP community has any interest in. > As the PostgreSQL advocacy group thinks that PHP programmers are among > their *main* target audience, may I humbly suggest answering the > questions that are asked instead of the ones that are not? Well, the first question I would ask *us* is whether or not PHP programmers *are* among our main targets for advocacy. Based on my experience at PHPCon, I would say that 80% of PHP coders would be well served by SQLite -- MySQL is more powerful than they need or want, let alone us. Not that I'm writing off the PHP community. Given PostgreSQL's powerful functions, views, and other in-database code, it makes a really dynamic pairing with a lightweight scripting language like PHP -- one which I've used to great effect. But I think that the target audience for this message is not necessarily existing PHP jockeys, but rather coders in client-side languages, and database designers used to Oracle and MSSQL, looking to move to the web. Overall, though, if you look at PostgreSQL adoption in my area (the San Francisco Bay Area and Silicon Valley), it's at least 80% Java and J2EE. In fact, of the 6 new clients I've signed in the last year, all of them were using Java as middleware and client. > The most successful (most quoted) advocacy articles I remember were the > once from OpenACS (Why not MySQL?) and sql-info.de (MySQL gotchas).

Unfortunately, this sort of propaganda can also backfire dramatically; the danger of mud-slinging is that you always seem to get some on yourself as well. Maybe it's different in Russia, but in the US I'd advocate pretty strongly against any really aggressive trashing of MySQL; the winner in that is liable to be the proprietary databases, not us. If you really want to reach the PHP coders where they live, though, just point out MySQL's licensing policy. If they want to use MySQL and *not* open-source their entire site, then they have to cough up $300 to $500US to MySQL AB as a commercial license, and pay for *each server* they use. That's a persuasive reason to switch to PostgreSQL. You can also point out that MySQL AB has changed the MySQL license 3 times since 2.0; what's to keep them from closing it entirely, and eliminating the Open Source version, if they feel it will be profitable? -- Josh Berkus Aglio Database Solutions San Francisco
Remember that MySQL for better or worse is tacking on features that Postgres was designed for 15 years ago. You could always do subqueries of a kind by using functions in the where clause. Surfacing the SQL only in 7.1 surprises me. elein On Mon, May 24, 2004 at 10:17:37AM -0400, Jan Wieck wrote: > Martin Marques wrote: > > > El Sáb 22 May 2004 20:00, Robert Bernier escribió: > >> http://det-dbalice.if.pw.edu.pl/det-dbalice/ttraczyk/db_compare/db_compare. > >>html > > > > I don't know when they wrote this but...: > > > > > > Subqueries in FROM clause > > > > Possibility of using subquery (nested query) in FROM clause of SQL query. > > > > MySQL: > > No. Will be added in next versions. > > > > Oracle8: > > Yes. > > > > Postgres: > > No. The feature will be supported from version 7.1. > > > > > > When was 7.1 released? 2001? > > Yeah, and funny enough, it's still "to be" included in the next version > of MySQL ... and what they have so far for 4.1 (in the 4.1.1 Alpha) is > one implementation of subselects for the FROM clause and apparently > another one for the WHERE clase (this is an assumption based on the fact > that subselects support different language features if they are in the > FROM clause or the WHERE clause).

Well, they are somewhat different. For example, Russian version of MySQL's manual still sports the famous comparison with PostgreSQL: http://dev.mysql.com/doc/mysql/ru/Compare_PostgreSQL.html >>As the PostgreSQL advocacy group thinks that PHP programmers are among >>their *main* target audience, may I humbly suggest answering the >>questions that are asked instead of the ones that are not? > > Well, the first question I would ask *us* is whether or not PHP programmers > *are* among our main targets for advocacy.

That 80% of PHP coders do *not* go to conferences and are indeed best served by SQLite. But I am speaking about the other 20%, and if some of them switch that'll be extremely good: * advocacy within the community * quality web apllications that support PostgreSQL > Not that I'm writing off the PHP community.

OK, let's replace "PHP developers" by "current MySQL users". My point being, that most of them already know about features, and some of them even *want* these features. While there are some real problems preventing them from switching (lack of Win32 port, for instance), there also are some imagined ones and the natural aversion to change. >>The most successful (most quoted) advocacy articles I remember were the >>once from OpenACS (Why not MySQL?) and sql-info.de (MySQL gotchas).

Yes, and that is precisely the approach I called "creating a sense of insecurity". "You can get fired for choosing MySQL", "what happens when MySQL AB goes bankrupt?", etc. :] The recent article on licensing problems was noticed *very* well. I'd like to suggest doing the same things in technical perspective: why implementing the functionality on client side is *bad*, length of MySQL's release cycles, creating some "switching" stories, this kind of stuff.

The licensing leaves many developers untouched as long as they don't mess with MySQL Libs.

IMO, that's a great point. PostgreSQL seems like it's a good DBA's database and bluntly, MySQL is not. The inverse, I believe, can also be said. Which is, PostgreSQL is currently not a non-DBA's database. MySQL, on the other hand, gets lots of exposure to non-DBA's and does quite well. We really need some advocacy that talks to non-DBA users rather than the more technical crowd where PostgreSQL has long been well received. I would think the PHP crowd would fall more toward the non-DBA direction. -- Greg Copeland, Owner greg@copelandconsulting.net Copeland Computer Consulting 940.206.8004

I am opposed to "advocating PostgreSQL" in this manner (regardless of how effective it may or may not be). Promoting PostgreSQL ought to be centered on explaining why PostgreSQL is a good DBMS, not trash-talking the competition.

I am not suggesting forcing PostgreSQL down the throats, either. I am speaking of people who may benefit from the switch (e.g. people who right *now* are considering switch to MySQL 4.1 or even 5.0), but need some *additional* push in the right direction.

(Or, to be more precise, doing _even more > hideous_ things ;-).) Exactly! The more "idiots" we make believe that we think PostgreSQL is the tool for them, the more "idiots" will run this sophisticated crashme (doing 10,000 CREATE TABLE, DROP TABLE), or they run the 571st variation of 10,000 INSERT, 10,000 single SELECT over one connection "benchmark". And this is not because they are biased, it is because that is the level of complexity they are capable of. They don't even think there could be something wrong with it, they are that simple. They do not need stored procedures because what they do can be done in 5 lines of PHP code. They do not need a view because there are only 3 tables in their schema. And they do not need MVCC because the 24 site hits per day querying 8 rows in their database wouldn't really benefit from it anyway. However, when they "port" their "applications" to PostgreSQL, it'll produce a lot of stupid noise based on ignorance and incompetence, with the net result that they "stick to MySQL" anyway. Nobody please get this wrong, there are a lot of serious people using MySQL today who are in need of a strong and powerfull database system. That is the reason why MySQL is tacking on features like crazy, features they have ignored for way too long. But those people do understand what we're talking about when we're doing it on the DBA level. We don't have to get down to the database-baby-talk. In fact, I think MySQL AB is currently talking exactly in that way, about 5 9's, NDB HA-clustering "integrated" into the "MySQL database engine". This is marketing babble directed at PHB's, bacause what they really "have" is yet another loosely tacked on table handler. Sure, it's linked into the same executable, but my understanding of "integration" goes a little further. Anyhow, what they do is they talk to "our" customers, the PostgreSQL users. They tell those who are waiting for replication and PITR that MySQL now has referential integrity, and that the next version will have multimaster replication while we are trying to educate dumbass PHP coders that transactions are a good thing (tm). That their multimaster NDB "sticker" is not integrated with the rest of the nice features like foreign keys doesn't matter. They get the foot into the door that way. And we all know that PHB's rather ruin a company than admitting to have been pulled over the table by a sales guy.
