| Janko 9-Sep-2012 [200x2] | 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) | |
| DocKimbel 9-Sep-2012 [202x2] | 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... | |
| Janko 9-Sep-2012 [204] | 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? |
| DocKimbel 9-Sep-2012 [205x2] | http://softinnov.org/tmp/mysql-protocol-41.r |
Yes, the link from the blog entry is the right one too. | |
| Janko 9-Sep-2012 [207] | thanks! I will try it ... otherwise I will reinstall mysq 5.1 |
| DocKimbel 9-Sep-2012 [208] | Ah right (reading the blog article reminded me a few things), the multiple results reading + stored proc needed more tests. |
| james_nak 9-Sep-2012 [209] | I've been relying on 4.1 for a long time now. No problems so far. Thanks Doc. |
| DocKimbel 9-Sep-2012 [210] | You're welcome. |
| Gabriele 10-Sep-2012 [211] | 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. |
| Chris 25-Sep-2012 [212x3] | 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. | |
| Kaj 25-Sep-2012 [215] | Did you port WITH from Red/System? ;-) |
| Chris 25-Sep-2012 [216] | No, just an old QM function : ) |
| Kaj 25-Sep-2012 [217] | Ah, I remember now |
| Chris 25-Sep-2012 [218] | Erk, fixed a couple other dependencies, d'oh! |
| Endo 26-Sep-2012 [219] | Very nice work Chris. It would be nice to have that for MS-SQL too. |
| Chris 26-Sep-2012 [220] | 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... |
| afsanehsamim 9-Nov-2012 [221x2] | 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 | |
| Arnold 9-Nov-2012 [223] | Show what you have got so far, may be you are close. |
| afsanehsamim 9-Nov-2012 [224x9] | 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"]

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 | |
| Arnold 9-Nov-2012 [233] | what did the probe results show? |
| afsanehsamim 9-Nov-2012 [234x5] | in rebol interpreter only created table |
i mean when i run data.r it creats table | |
i do not know how should i mix cgi file with database file | |
the results is like this: | |
do %data.r
Script: "Untitled" (none)
Script: "MySQL Protocol" (12-Jul-2008)
MySQL protocol loaded
connecting to: localhost
[
["raj" "pune"]
["ekta" "delhi"]
["ankur" "mumbai"]
]
| |
| Arnold 9-Nov-2012 [239] | you have to mix them something like
#! "C:/wamp/bin/apache/Apache2.2.11/cgi-bin/rebol-core-278-3-1.exe"
-cs
REBOL [Title: "Table"]
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
print "content-type: text/html^/"
print [<HTML><BODY><TABLE bgcolor="black" border="1">
{
<tr bgcolor="white">
<td style="width:30px; height:30px;"><input name="one-one" type="text"
size="1">}
print results/name
print {</td>}
etc

| afsanehsamim 9-Nov-2012 [240] | and what extension should i use ? .r ???/ |
| Arnold 9-Nov-2012 [241] | learning comes with a lot of try and err even for a 'simple' language as REBOL Probably yes and have your apache server set up right for .r files |
| afsanehsamim 9-Nov-2012 [242] | you're right,i configured my apache server for cgi ... i think i should configure again |
| TomBon 9-Nov-2012 [243] | just rename it to .cgi you have the correct shebang at the top. apache should recognize it automatically. don't forget to chmod your cgi to grant execution permission. |
| afsanehsamim 9-Nov-2012 [244x2] | but my OS is windows 7 |
i am not using linux | |
| BrianH 9-Nov-2012 [246] | Then you don't have to chmod, you just have to put it in the right directory. |
| TomBon 9-Nov-2012 [247] | correct |
| afsanehsamim 10-Nov-2012 [248x2] | thank you Arnold.... i van fetch data from database :) ...i am working on compare two values (value that is entered by user and value that is correct )... |
do you know for comparing which aommand should i use? | |
