unicode charset support ?
hi mysql guru's, does anyone put light on the unicode charset support of MYSQL? i searced everywhere in the archives and the docs , but couldn't find a related thing.It seems that it doesn't support, however i am asking you to be sure. My application needs to save both japanese and chinese charsets, thus i must use unicode to support both of those charsets. So far i was using mysql jsut for big5(traditional chinese ) charset, it was working okey.When i try to save japanese characters i am having trouble, the characters become garbled.??? Any one who knows the solution for this. thanks for helping me. (note: my mysql version is 3.23, os is win2000) - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Too many connections (again) (could Mark answer this please)
thanks a lot Mark,
now i figured it out, i should have used finally {} statements around
close() functions.
Best regards :)

I've answered this twice, both in personal e-mails, but I'll answer it
again, one last time :).
Three things, First, you're using an old version of the driver. Please
upgrade to the latest (you should do this when you suspect it might be the
driver. Always check http://mmmysql.sourceforge.net/ as this is
_the_only_official_ MM.MySQL download site. I can't vouch for anything you
download from somewhere else).
Second, you are not closing your connections in finally{} blocks, so you
can
not guarantee that they are being closed! Many browsers terminate the
connection to the servlet/JSP early (IE for example), which can cause code
you think should be executing not to execute. You should _always_ get rid
of
expensive resources in a finally{} block to make sure that it actually
happens.
Third, please subscribe to the [EMAIL PROTECTED] This forum is not the
correct place to ask these types of questions, and I only get it in digest
mode, so it takes me a while to read/get back to people who ask JDBC
questions in the mysql list.
-Mark

Me , too, have the same problem.
it seems that every opened page establishes a connection but
those connections can't be closed, although i explicitly close in my code
I posted a message related with this problem a few days ago,
unfortunately couldn't get a satisfying answer. So, i request from Mark
Matthew
to help us with this problem , since he is the author of Mysql.
(my Mysql version is 3.23 , i use jdbc through tomcat 4 b7, on win 2000.)
Thanks in advance

Re: number of connections keeps increasing
Hi takashi,
My environment is :
Win2000, jdk1.3, tomcat 4,
Well, i am sure i added a snippet which closes statemnt and the connection.
for example, below is the snippet from one of my pages content.jsp :
% if (stmt!=null) { // actually this is a curly left brace
stmt.close(); } // actually this is a curly right brace
if (conn!=null){ // stmt is a Statement object
conn.close(); // conn is a Connection object
} %
whenever i call this page , number of connections inreases by one
it seems that the connections can not be closed
Any idea or suggestions ?
thanks a lot in advance
best regards :)

nested select queries
hi everybody, i have a simple problem, but somehow i couldn't solve it i hope someone overthere can help me. i have a select query as below: select no,subject,ndate from cat1 where news like '%+search+%' limit +page_no+,5 i also want to find out how many rows are there in the result set. what is the easiest way to do this? actually , i wonder if there is a facility such as: select count(*) from (select no,sub.) but this doesn't work. is there a similar way? the only way i could think of is creating a table with the first select query and then counting it eg: query1=create table temp as select 'query1' select count(*) from the_table_resulted_from_query1 but this seems too inefficient and stupid way. any one has a better idea? thanks a lot? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

how to auto_decrement a primary key?
Hi all, i want to keep the track of row numbers to display the results , say, five by five. the most common way to do this is defining a column which is auto_incrementing and not null. but htere is a problem with this approach. say, i have a table which stores the subject and contents of articles, and it has a primary key, say pk. since pk is auto incrementing , whenever a new article is added it will increment by one.However, if i delete an article ( a row) it will not decrement. So when i want to display them five by five, i will have trouble, because some numbers do not exist. In oracle there is an imbedded variable called rownum, so that you can workaround this. Is there a similar varible or a kind of solution for this problem? i am looking forward to your help, and suggestions. many thanks in advance cheers :) - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
