Simply put - millisecond lock time is enough fine grained for my 
purposes, but - let's assume you have several ppl working on some 
customer list, where each customer has some orders. Those ppl do 
select particular customer, and work with orders. What I want is 
- when some user selects particular customer, I need its record being 
locked. The trouble is, that when I use BEGIN transaction for sqlite, 
it locks all the file, and does not allow other process to do write 
to the DB.


I wonder, if I can somehow obey it, not really having per record 
locking. I would have to implement my own lock mechanism (not locking 
in fact), not allowing others select/enter customer record, when 
some other person is working on it?

Or simply I have to use more powerfull SQL solution, but heck, I 
don't like all the heave SQL servers for some simple few tables solution 
....

It's interesting when I try to connect using a port scheme I cannot 
get error msg:

>> con: open [scheme: 'odbc target: "..."] ;try with wrong password 
for example
** Script Error: ODBC error:

>> con: open odbc://sa:[qwe1234-:-mydsn]

** Script Error: ODBC error: [Microsoft][SQL Server Native Client 
10.0][SQL Server]Login failed for user 'sa'.  <<< now I got error 
msg.

Any idea how to get "real" error message?

Shouldn't that rather be HOST instead of TARGET?
>> con: [scheme: 'odbc host: "mydsn"]

Only if the target is a DSN with no other settings specified. Otherwise, 
use target.

con: [scheme: 'odbc target: "dsn=mydsn"]

For instance, this is a common connection I use at work (server name 
changed):

conn: [scheme: 'odbc target: "driver=SQL Server Native Client 10.0;server=SERVER1;database=db1;Trusted_Connection=Yes;"]

I've just updated the R3 ODBC Extension to work with more SQL types 
and, with the support of BrianH, fixed and improved the boot code 
OPEN and COPY actors.


The extension is available over at Github in both source form as 
well as a DLL compiled for windows, see https://github.com/gurzgri/r3-odbc

dll compiled means use from R2?

It's an R3 extension. You could load it in R2, but you'd have to 
program the interface to the extension yourself

Is anyone using Doc's MySql protocol (v4.1 1.3.0) with MySql 5.5.24-cll, 
protocol v10? 


I have a client migrating to a new host. We've been using 1.2.1 against 
mysql 5.0.95, but 5.5 triggers the client auth error. Moving to Doc's 
4.1 version solved that, but a simple test query returns an empty 
block. 


Can't rule out a data migration error yet, as things just moved and 
getting connected was the frist step. Just curious if someone is 
known to have this combo working.

Nevermind. I was able to test another query which works, so all is 
well there. Thanks Doc, once again!

The failing query was a data migration issue, just FYI.

I just upgraded local ubutu and I made the rebol work with ia32-libs 
again, now rebol mysql client is givin me auth error

Gregg: what did you say you did to make it work? what did you move 
to 4.1 the mysql server or something else?

Janko: if you're using a newer MySQL version, you need my 4.1 driver.

aha, I hoped he meant that :) , but I only found 1.2.1 on your website

I am looking at this page http://softinnov.org/rebol/mysql.shtml
(google doesn't find me any ohter, I think)

It's not an official release yet...I wish I had time to finish it...:-/

IIRC, it was missing some minor feature support from the protocol 
and good new test cases...

well if it works for what I need it it's ok with me (I just use mysql 
for user db so it's rather simple). I found mention of it here now 
http://rebolweek.blogspot.com/2008_12_01_archive.htmlis this the 
latest version you have?

http://softinnov.org/tmp/mysql-protocol-41.r

Yes, the link from the blog entry is the right one too.

thanks! I will try it ... otherwise I will reinstall mysq 5.1

Ah right (reading the blog article reminded me a few things), the 
multiple results reading + stored proc needed more tests.

I've been relying on 4.1 for a long time now. No problems so far. 
Thanks Doc.

You're welcome.

I've also been using it for a very long time. Sadly, not a lot testing 
with multiple result sets as we don't use this on production, so 
i can't use multiple result sets. :( it did work correctly with simple 
tests.

Thought I'd share this in case anyone found it useful (or had any 
suggestions/criticisms).  First part is a description in REBOL of 
a database schema (sample here: http://reb4.me/r/schema-sample), 
second part is a function that generates the MySQL code to create 
the database/tables. I'd like to add functions to analyse database 
schemas against my REBOL schema and create 'ALTER' statements as 
necessary.  All in good time...

do http://reb4.me/r/schema
do http://reb4.me/r/mysql-schema
print schema-create load-schema http://reb4.me/r/schema-sample

Definitely a work in progress, but has saved me some time.

Did you port WITH from Red/System? ;-)

No, just an old QM function : )

Ah, I remember now

Erk, fixed a couple other dependencies, d'oh!

Very nice work Chris.  It would be nice to have that for MS-SQL too.

By the looks of it (I've not used MS SQL) it wouldn't be too different. 
Same for Sqlite. Just a matter of hacking http://reb4.me/r/mysql-schema
to include the most appropriate datatypes.


Of course, that's only for the 'create statement. I imagine detecting 
differences in schemas between SQL dialects might be more nuanced. 
But then I haven't got that far with any dialect of SQL, so...

guys , i have one project (crossword )which uses mysql database! 
i want use mysql driver ,i know how  we can create table and make 
connectivity with database !  crossword should show on web page ,and 
when user put characters in each field ,then press button ,it will 
chek with database and if it is correct ,user can continue otherwise 
shows error message ....i created crossword table with cgi and is 
working on web ,i have created database as well,now my problem is 
i do not know how can i fetch data and comparing with database? is 
there anybody for helping my mini project????

i need only simple example of that ...plz help me if you can ... 
i do not have time :( ...i am very begginer in rebol

Show what you have got so far, may be you are close.

my understanding of work steps is : i have two files *.cgi and *.r 
 ,in cgi file i created crossword that shows on web page ... in data.r 
 i have made connectivity with database and create table ... and 
my codes are as following : in cgi file:

#! "C:/wamp/bin/apache/Apache2.2.11/cgi-bin/rebol-core-278-3-1.exe" 
-cs
REBOL [Title: "Table"]
print "content-type: text/html^/"
print [<HTML><BODY><TABLE  bgcolor="black" border="1">

}
]
print [</TABLE></BODY></HTML>]

and my data.r codes :

sorryyyy

this codes:

REBOL []
do %mysql-protocol.r 
db: open mysql://[root-:-localhost]/test
insert db {create table data (
    name            varchar(100),
    address         text
  )} 
insert db {INSERT into data VALUES 
    ('raj', 'pune'),
    ('ekta', 'delhi'),
    ('ankur', 'mumbai')
    
}
insert db "SELECT * from data"
results: copy db
probe results
close db

the second file is only exaple of connectivity

table is differenet

what did the probe results show?
