newlisp to get mysql table command lead to messy code

Post by shanquan2006 »

I study newLisp for two weeks. Now I was trying to connect mysql to get "create table sql", but it cause messy code .

the code is :

Code: Select all

 
 (:connect db mysql-host mysql-user mysql-pwd mysql-db mysql-port) 
 (set 'r (:query db (append "show create table " mysql-table-name)))  
 (set 'mysql_sql ((((:fetch-all r) 0) 1) 1))   
 (println mysql_sql )
the result is :

Code: Select all

CREATE TABLE `tvsn` (
                `order_id` varchar(13) NOT NULL COMMENT '??ID',
                `sn` varchar(50) NOT NULL COMMENT '??SN?'
               ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='???????SN?'
but in mysqlclient, the result is :

Code: Select all

CREATE TABLE `tvsn` (
  `order_id` varchar(13) NOT NULL COMMENT '订单ID',
  `sn` varchar(50) NOT NULL COMMENT '电视SN码'
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='电视机SN码'        
some description of mysql.lsp is:
;; @module Mysql
;; @author Jeff Ober <jeffober@gmail.com>, Kanen Flowers <kanendosei@gmail.com>
;; @version 1.05 beta
;; @location http://static.artfulcode.net/newlisp/mysql.lsp
;; @package http://static.artfulcode.net/newlisp/mysql.qwerty
;; @description A new MySQL module to replace the distribution standard module (requires newlisp 10).

how to solve it ?

Maybe you don't have installed the UTF-8 version? http://www.newlisp.org/index.cgi?page=Downloads

The version I installed is:

Code: Select all

-OptiPlex-3020:~$ newlisp --version
newLISP v.10.6.0 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h

A quick glance into the source indicates that "println" is not very i18n friendly, though I don't have too much experience with it myself. Thus, my theory is that the string in newlisp is correct (i.e., the same as the other), but presented badly by println. Maybe a raw string output works better?

Code: Select all

(write 1 <text>)

I modefied the program with your mehod, but the question is sitll not to solve.

Code: Select all

 (write 1 ((((:fetch-all r) 0) 1) 1))  

and I checked mysql code is

Code: Select all

mysql> show variables like 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

Maybe you can explain the problem a bit more in detail.

I understood it to be that the strings in the COMMENT phrases look different in the newlisp printing than in your 'mysqlclient', which by extension might lead us to assume that the string values are different.

My theory was that the string values are actually the same in the programs, but they get presented differently; maybe it is that the console shows unicode characters, and mysqlclient has a utf8-to-unicode filter, whilst newlisp doesn't. How about saving the newlisp output to a file, and then you view this with your utf8 aware text editor?

Or maybe I don't know at all what I'm taking about and should sit quiet for a while.

I fixed this problem. Just execute the following commands in newlisp before querying data from mysql table.

Code: Select all

(MySQL:query "SET character_set_client = utf8;")
true

(MySQL:query "SET character_set_connection = utf8;")
true
 (MySQL:query "SET character_set_results = utf8;")
Then check it:

Code: Select all

> (MySQL:query "SHOW VARIABLES LIKE 'character%';")
true
> (dotimes (x (MySQL:num-rows)) (println (MySQL:fetch-row)))
("character_set_client" "utf8")
("character_set_connection" "utf8")
("character_set_database" "utf8")
("character_set_filesystem" "binary")
("character_set_results" "utf8")
("character_set_server" "utf8")
("character_set_system" "utf8")
("character_sets_dir" "/usr/share/mysql/charsets/")
("character_sets_dir" "/usr/share/mysql/charsets/")

This is now part of the documentation: http://www.newlisp.org/code/modules/mysql.lsp.html for the standard module.
