I have a new mysql server but I can't connect to it with %mysql-protocol 
v1.2.1 :

>> open mysql://user:[traiteur-:-localhost]/testjmg
connecting to: localhost

** User Error: ERROR 1251 : Client does not support authentication 
protocol requested by server; consider upgrading MySQL client
** Near: open mysql://user:[traiteur-:-localhost]/testjmg


I know I have to change something in the mysql server configuration, 
but does anyone can point me to what it is ?

there are two types of authentication schemes ... IIRC, onwards from 
4.1 or 4.0.1 mysql switched to stronger authentication. So - if you 
upgraded or used older DBs, you have to explicitly set old auth method 
...

It's MySQL - 5.0.51a
Do you know how to do that ?

I'm using 5.0.18 and don't have such issues. Anyway to find a fix, 
have a look here : http://dev.mysql.com/doc/refman/5.1/en/old-client.html

Start mysqld with the --old-passwords option. 
 seems the simpliest way to workaround that.

Btw, you should check if your code is not using an older version 
of %mysql-protocol.r (just in case you're reusing old source files).

Just installed 5.0.77 community server on Windows, no problem to 
log in using default password mode with mysql protocol v1.2.1.

OK, old-password is off in the server variable. Do you know where 
is the config file where this variables are sets (Ubuntu) ?

Client version is the last one.

(I just look at the variable in phpmyadmin.

Does protocol v1.2.1 works with new password method ? If so, maybe 
I just need to update the user password int he db ?*

v1.2.1 is supposed to work with both old and new passwords.

MySQL config file (my.cnf) can be in one of these places :
- /etc/
- $HOME/ 
- MySQL data folder

Ok, it works now. My bad, I put the last protocol in a folder but 
I where still loading the old one from another folder !

Can you create a database remotely?

Anyone know the syntax?

I tried:
insert db [create-db "test2"]

with db=port but does not seem to work

Is there a limit to the number of tables in a database?

Anyone know SOP for this situation:

 I have hundreds of users (not yet really) )and I need to store several 
 tables of user data for each. Should I create a seperate database 
 for each user or is it better to use a naming scheme for the tables 
 and store all of them in one database? or is it just personal preference?

insert db "SELECT * FROM user"

insert db "CREATE DATABASE test2"

forget the first one:)

I don't know details, but I think one database should be enough

Thanks olds...I think that will making everything simpler for me 
too.

Oldes

I think there is no limit on number of tables. A database in MySQL 
is implemented as a directory containing files that correspond to 
tables in the database.

I still can't create db but never mind as I'm going with tables...Thanks 
again

I got it!

insert db [create-db "test2"] works flawlessly here....You've probably 
connected to the server with a user that didn't had enough rights 
for creating databases, but it's hard to figure out from a "does 
not seem to work" issue description.


I start to better understand Carl's willings for filtered communication 
channels that improve the signal to noise ratio in order to save 
some valuable working time...

I've run into situations where MySQL will fail to do DDL without 
throwing an error, at least not one the mysql:// driver notices. 
Haven't tested with the /Command driver or qcmysql:// though.

The DDL in question is create table statements where some obscure 
semantic rule is violated. By obscure, I mean it took me a day to 
track down the error in the MySQL manuals.

You should try with the official command line mysql client. If you 
notice a different behaviour than the mysql:// driver, please report 
it here.

Does the /Command client support MySQL 5.1?

Don't know, I think it doesn't support anything above 3.x but I can't 
find the full /Command feature list on rebol.com to confirm.

Btw, I've never tested my driver with a 5.1.x server.

Yeah, but you're driver has the source. Also, in the ancient times 
before COmmand 2.x and your mysql:// I did a library interface, it's 
still on rebol.org

I use your driver with 5.1.x no problem 8-)

Good to know! Thanks.

for large query results is there a way to show a progress bar as 
an indicator of the download progress?

Is there some type of callback method like "read-net"?

No, there's no such callback. But you can easily add one in my driver 
by inserting a call to "read-net" in the FOREVER loop inside READ-ROWS 
function. Can you describe briefly the situation where you need to 
get large query results and display a progress bar (just curious)?

I'm hosting a large number of text docs broken up by sections in 
a mysql db. Once all the material is on line the changes (and thus 
downloads) wil be smal for the most part. But in the mean time large 
amounts of material are still to be uploaded to the db and when a 
client finds this new material it will download it and any changes 
to previous material. The material contains a lot of image data too 
so it could add up. Right now I have about 40 megs of data and I 
have about 10X more to upload.


If its too tuff for me I will just display some animated gif but 
I would prefer something more tangible..

I'll look into your suggestion, Thanks Doc...


BTW I tried the latest mysql-protocol and it broke my app. I have 
not had a chance to look into it but I think you changed some syntax 
for selects??
I'm using Version: 1.1.2 at the moment.

Thanks for the additional info. The main change in 1.2.0 is the new 
READ syntax, and it's documented here : http://softinnov.org/rebol/mysql-usage.html#sect2.2.

Doc, I played around with read-net but no luck.

Would not read-net need to know total size of query result to work?
Does the server send this info first?


also, read-net wants a URL. Where am I pointing it to? Is this the 
same as the db port i'm using?

I'm just understanding now what you're trying to do. READ-NET is 
not what you want to use, it's for downloading files! You have to 
write your own progress bar function. About the total size of result 
set, AFAIK, MySQL server doesn't send that information, it just marks 
the last record of a result set.

Thanks anyway...

Has anyone released a sphinx Rebol client api implementation?

There is this API document being worked on http://sphinxclient.codeplex.com/SourceControl/ListDownloadableCommits.aspx

I have made a primitive client libs to the SOLR search engine, if 
that helps anyone

it's not much though - but I can share without problem if anyone 
needs

Can you put it on rebol.org in the library.

This is interesting http://sphinxsearch.com/news/37.html.. you can 
now connect to the sphinx searchd daemon using the mysql binary protocol 
... so doc's mysql driver can also now connect to sphinx??

I will put it on rebol.org
