hm... already found how to get the correct port number so now it's 
not important

New MySQL release 1.2.0 beta : http://softinnov.org/tmp/mysql-protocol.r

o Changed behaviour and syntax of the 'read command :

	read mysql://[root-:-localhost]/
	==> return the list of databases

	read mysql://[root-:-localhost]/db
	==> return the list of tables in database "db"

	read mysql://[root-:-localhost]/db/tbl
	==> return the description of table "tbl" in database "db"

	read/custom mysql://[root-:-localhost]/db ["...sql query..."]

 ==> execute the sql query on database "db" and return the resultset.

This new 'read implementation avoids the SQL encoding issues encountered 
in previous versions. The side effect it that it will break compatibility 
with previous sources using 'read.

Thank you Dock!

Congrats Doc.

MySQL driver release v.1.2.0 - Download at : http://rebol.softinnov.org/mysql
- Changed behaviour and syntax of the READ function.
- Fix for parsing correctly quoted empty strings. (Fix by Oldes)

- Fix for the driver loosing local flags, like 'flat, 'auto-ping?,... 
when reconnecting (thanks to Will Arp)

- Fix a remanence issue on /flat and /raw flags in 'send-sql after 
automatic reconnection. (thanks to Will Arp)

- Improved port recovery support after a failed request upon a shutdown 
server.
- An init SQL string can now be specified for an opened port.

Doc, first of all, thanks for the driver. It is amazing. Secondly, 
I've tried a few ways to be able to detect for an open port without 
the program erroring out. I've just settled on a "error? attempt 
[db/locals]" Do you have any recommendations?

some nice performance tips http://www.scribd.com/doc/393792/MySQL-performance-coding

Read the comments: The CEO of MySQL sets the story straight.

Does anyone experimented with the sphinx search engine? http://www.sphinxsearch.com/

Here's a handy function to test if a MySQL server is up :

mysql-alive?: func [/host ip /port n /local p][
	either attempt [
		p: open/direct/no-wait join tcp:// [
			either host [ip][127.0.0.1]
			#":"
			either port [n][3306]
		]
	][
		close p
		yes
	][
		no
	]
]

you can also use a simple : port: attempt [ open mysql://... ]

ok but your driver should reconnect automagically 8-)

Yes if the server is just restarted, no problem, the driver will 
reconnect.

You rock Doc. Thanks. That was an answer several years in the making!

Will, I have, and for Qtask I have even implemented the search protocol 
in REBOL. It's fast.

(i.e. the search client protocol that can talk to Sphinx). You can 
also compile a client in mysql and then use sql for your queries.

Maarten: that is great news! Do you plan on releasing it for the 
rest of us?

would there be any advantage having rebol as an external language 
plugin compared to Dock sheme?

http://forge.mysql.com/wiki/ProjectPage_External_Language_Stored_Procedures

bad question, but it would be cool to program stored procedures in 
rebol

here is a short and concise presentation about sphinx http://www.scribd.com/doc/2670976/Sphinx-High-Performance-Full-Text-Search-for-MySQL-Presentation

Will: I'll have to ask Reichart.

Please 8P

Guys, what do you think about Tim Johnson's ml remark? Could we help 
him somehow?

-----------------------------------

I've been using mysql-protocol (Mysql Scheme) and cgi for many years 
now. I 

really like it, but I think that /command would bring some advantages, 
if
it can directly access the "C" API for MySQL.


Example: Using the mysql scheme on a tcp/ip connection, I have to 
code

the escaping of special characters for insert and updates and code 
the
unescaping of special characters for retrieval. 


Using the C API from other scripting languages, the mysql_real_escape_string()
function handles the escaping _appropriate_ to the version, and
queries are similarly unescaped.

Isn't REBOL fast enough for most operations in regards to MySQL? 
Wouldn't it be sufficient to write such escaping fun in REBOL?

about escaping, Nenad's driver has such functions already, so i don't 
see that as an advantage for the native driver. Qtask has a native 
driver too (for speed reason with large record sets), but remember 
that when you use the mysql c library either your app has to be GPL 
or you need a license from MySQL (Qtask has a license).

I have a mysql wrapper that I use in production but haven't released 
because it need cleaning and docs, but if there is interest I could 
release for testing as is. id does things like:

print .db/get/all/sort/debug [mailing/m mailingLog/ml] [ml.dc m.email 
ml.url] [{ml._mailing=m.id}] [m.email asc ml.dc desc]

SELECT `ml`.`dc`,`m`.`email`,`ml`.`url` FROM `mailing` `m`,`mailingLog` 
`ml` WHERE ml._mailing=m.id ORDER BY `m`.`email`,`ml`.`dc` DESC
print .db/set/debug 'mailing 12 reduce['active false] 
UPDATE `mailing` SET `active`=0 WHERE id=12.0

print .db/get/all/flat/debug '_node_tree [_node _media] [{_tree=? 
AND _issue=?} 5443 22]

SELECT `_node`,`_media` FROM `_node_tree` WHERE _tree='5443' AND 
_issue='22'
..

Will, that would be sweet.

Gabriele, I thought you only needed a license if you are releasing 
your software ....

graham, i'm not entirely sure, in principle the GPL2 is as you say, 
however i'm not sure if MySQL has a different interpretation here. 
iirc the GPL3 states that being a server for users is the same as 
releasing the software.

No, that's the Affero GPL.

They took that clause out of the regular GPL3 during the review process, 
after many protested it.

So, looks like you didn't need a license

Qtask? no, it does, because you can also put qtask on your own server.

Has that happened yet?

i don't think you can buy it right now, and the focus has shifted 
to the SaaS model, but otherwise there are no major tech obstacles 
iirc. ask reichart for more details, i'm not really up to date on 
the marketing/sales stuff :)

He's often mentioned that they are considering open sourcing qtask 
in which again the license was not needed!

well, not all of qtask, but again i don't really know. i know they 
talked to mysql and all is fine. i'm not implying they paid or are 
paying money, since i don't know. my point is that Qtask has permission 
from MySQL to do what they do, while you may not if you were to use 
the same code. Is that more clear?

Why didn't qtask use postgresql instead??

Why is the world flat?

because of a limited viewpoint

I agree, your viewpoint wasn't economics....

With two open source databases to choose from of approximately similar 
functionality and stability, it is hard to understand why one would 
choose the one that has the restrictive license ... I can only imagine 
it is a mind share thing.

James, thanks for your interest, I' ll upload it in a couple days 
8)

Thanks.

Why wouldn't Qtask want to talk to Postgres too if they had chosen 
it?

Qtask might do this in the future...

Never used mysql before .. and just downloaded Nenad's driver.
