Hi again,
I have it working. Here is my working script:
on mouseUp
global vDatabaseID --database ID
--magic command for UTF8/mySQL, from forum user "bancock
--without this I cannot send or receive UTF8 from mySQL
revExecuteSQL vDatabaseID, "SET NAMES 'utf8'"
--fld "query" contains SQL query, English & Japanese text
put the unicodeText of field "query" into locSQLParams
put uniDecode(locSQLParams, "UTF8") into locSQLParams
put revDataFromQuery(, , vDatabaseID, locSQLParams) into myResult
--fld "queryresults" holds data returned by mySQL
--works great; get a field that shows the returned English
and Japanese
set the unicodetext of fld queryresults to
uniEncode(myResult, "UTF8")
--adding "unicodetext" to any part of "dgtext of group
results causes error
--following line does NOT work. Japanese text is broken in
datagrid
set the dgText of group "results" to uniEncode(myResult,
"UTF8")
end mouseUp
My next problem, though, is that while I can get the returned
Japanese into text or table fields, I cannot get it into a
datagrid. I have googled, as well as read (again) all the unicode
and datagrid lessons on the runrev.com site. Their lesson uses a
dummy button to set a custom property?? I did the steps without
really understanding them... with predictable (non) results!
Can anyone tell me how you get unicode text into a datagrid?
Thanks,

Tim,
I don't know the answers, but here are some thoughts based on my experience
with unicode text in SQL db's.

Starting to work with LC with a MySQL database on my on-rev.com account. Got
the database, user, table etc. made and imported all my data using phpMyAdmin
and can use the database with phpMyAdmin.
For testing purposes, I made some of the column names Japanese and some
English. (Ideally, I would like all column names to be in Japanese utf8.)
Everything works fine on phpMyAdmin, that is searching for Japanese data using
the Japanese column names works fine.
Wow, I didn't know you could even do that with MySQL!
On my stack, I have a fld "query" that has
SELECT *
FROM `tablename`
WHERE `県` LIKE '東京'
LIMIT 0 , 30
when I put that in a variable to send to the server, the variable replaces the kanji
characters with "?" -- whether the kanji is in the column name, or in the data
to search for -- and of course the search fails.
on mouseUp
global vDatabaseID
set useunicode to true
revExecuteSQL vDatabaseID, "SET NAMES 'utf8'"
I can't find anything on SET NAMES in my MySQL reference. What it is supposed
to do? I suspect that each revExecuteSQL instance is treated as a single
transaction. I wonder if you could put multiple SQL statements into a variable
and execute them all at once?
put fld query into dbsql
put revDataFromQuery(, , vDatabaseID, dbSQL) into myResult
put uniencode(myResult,"UTF8") into tData
set the unicodetext of field "queryresults" to tData
end mouseUp
<put uniencode(fld query, "UTF8") into dbsql> doesn't work either
How do I get the kanji/utf8 into a variable correctly?
Can anyone give me a pointer?
This is just an educated guess, but I believe that the LiveCode database libraries can
only handle ASCII characters when sending SQL statements to a database. The way I've
always handled unicode data in MySQL is to unidecode everything to UTF-8, insert/update
it to the database (so it essentially is stored as ascii), then reverse the process to
retrieve it and display it in LiveCode fields. If I need to do text comparisons in WHERE
clauses I do the comparisons using the "ascii-fied" text. Not the most
convenient method maybe, but it has been reliable for me.
