mySQL in Hebrew
Does anyone have any experience of working with mySQL in Hebrew? The front end to my database is written in Delphi/Windows; it transmits Hebrew characters and displays Hebrew characters. The backend is in mySQL/Linux, and what was Hebrew appears in English characters. The only problem which I have with this is that almost every table has a 'name' index, and the names aren't sorted in the correct order. I had a quick glance at the documentation regarding internationalisation and didn't completely understand it, so I am asking for help. Would it be a good idea to build a translation table, ie 'aleph' = 'a' and comes first in the sorting order? What about numbers and English names? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: How Do I Insert ...... ?
"where and how do I indicate that there is a problem
insert a row into the table 'message'?"
I don't understand you there.
INSERT INTO message(thread_topic, thread_body) VALUES ('This is a
topic','This is the body.');
That should work just fine.

Subject: How Do I Insert .. ?
I have a table 'message' in the MySQL database. To
make it simple; say, I have three fields in that
table: thread_ID, thread_topic, and thread_body.
The thread_ID field is AUTO_INCREMENT; therefore, I do
not insert any value into that column. The value of
that field starts with 1 when the first row is
inserted.
Now, I have the values for thread_topic and
thread_body and want to insert those values into the
'message' table to create the first record in that
table.
1. where and how do I indicate that there is a problem
insert a row into the table 'message'?
2. Do I code this way:
protected static void create(String threadTopic,
String threadBody) throws CreateException,
DatabaseException, ForeignKeyNotFoundException
{
StringBuffer sb = new StringBuffer(512);
sb.append("INSERT INTO " + message
+ "(thread_topic, thread_body)");
sb.append(" VALUES (?, ?)");
try
{
Connection conn =
DBConnection.getDBConnection();
Statement stmt =
conn.createStatement(sb.toString());
stmt.setString(1, threadTopic);
stmt.setString(2, threadBody);
}
catch(SQLException sqle)
{
sqle.printStackTrace();
throw new DatabaseException("Error executing SQL
in ThreadHelper.create.");
}
finally
{
stmt.close();
conn.close();
}
}

Selecting the latest entries
Hi there,
This subject might be discussed before, but I couldn't find any mail
from the archives.
I have a table containing weather reports of different types and cities.
The structure is following:
- type
- city
- time
- report
Which kind of query should I use to select the latest reports of
specified cities. I mean, if I had three different types of reports for
Helsinki and Turku, how can I get them all in one query?
One way is to make two queries: first to get the latest report time for
each type/city...
SELECT MAX(time) FROM reports WHERE city IN ('Helsinki', 'Turku') AND
type IN ('Observation', 'Forecast 1', 'Forecast 2') GROUP BY type, city;
... and then another query getting the report text for each time and
city and type.
Anyway I find this not very good one and now wondering if there is any
other way to make it in one query...
Thanks for any help. :)

creating a minimal mysqldump
I'm currently working on a little PHP-project, where I would like the possibillety of automatically upgrading the MySQL-tables, so that users don't have the need to drop the database, and then run the installscript again, from a mysqldump of the original database I'm running. What I was thinking, is a PHP-script that parses the running database, and a mysqldump --no-data of my database, and checks if it's something that doesn't match, and the run an ALTER TABLE of that. Instead of reinventing the wheel; I was wondering if anyone has a better solution to it Is mysqldump capable of if not exists field... alter table add column ?

Re: relative performance between innodb and myisam
Bruce, InnoDB in most cases uses some more CPU time than MyISAM. But the main performance disadvantage of InnoDB is that tables in the InnoDB format typically require 50 % - 300 % more disk space than MyISAM format tables. Marko Mäkelä of Innobase Oy is writing a new InnoDB table format which will reduce space usage substantially, maybe 30 % - 80 %. The new InnoDB table format will probably be available in some MySQL-5.0.x release. We will probably offer some PACK_KEYS=1 option in CREATE TABLE, so that the user can control the tradeoff between using more CPU time to compress/uncompress data, or using more disk bandwidth. You could find this from the TODO at www.innodb.com, but unfortunately our web host has technical problems, and the website is not accessible at the moment. Merry Christmas!

That's why I said "almost" a one-liner. You are also right that I got the perl line wrong. Considering how much perl I use, that's embarassing. Sigh. I have to admit I tested the sql I suggested but not the perl. I should have been more careful. Your regular expression isn't quite right either, though. The * means to match 0 or more, so [a-z]* will match the start of ANY string. That's why you needed the $ at the end, as it anchors the search to match at the end. Thus [a-z]*$ matches 0 or more lower case letters at the end. This is fine if there are any lower case letters in the string, but will put a / at the end of any string that doesn't contain a lower case letter. For example, it will turn "ABCD" into "ABCD/". It will also turn "ABcdEFg" into "ABcdEF/g". In other words, your version puts a / after the last non-lower case letter, instead of in front of the first lower case letter. To find the first lower case letter, we need to look for [a-z]. So the perl line should be $field =~ s/([a-z])/\/$1/ or, better yet $field =~ s|([a-z])|/$1| In vi, then, this would be :%s/[a-z]/\/&/ Michael -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Php > mysql question please help
I just started working with mysql and I'm very novice
Created a simple database and programmed php to connect as follows...
$link= mysql_connect($hostname,$user,$password)or die ("_something is
whong");
mysql_select_db($db,$link);
$query ="SELECT * FROM projects";
$result = mysql_query($query);
$array = mysql_fetch_array($result);
$usercount = mysql_num_rows($result);
mysql_close($link);
?>
Question 1
I put the files created from mysql(MYI ,MYD,frm) in the correct
directory at my site
Is this correct or do they need some kind of compilling?
Question 2
How do I Grant my host name and user name
I'm comfused..It gives me an error message Can't connect because of host
and user mistake..
Thanks Aaron
Hot standby database question
I would like to set up two systems, a primary, and a backup, in physically seperate locations. I want the backup to be synced with the primary, and if the primary goes down, dns will resolve to the backup, so it needs to be able to start processing transactions immediately. I am new to MySQL, and to SQL in general, I *think* I can do the first part (stay in sync with the primary) by making the backup a slave, and replicating the DB on a constant basis. But will the slave DB happily start accepting transactions when stuff starts coming in from the webserver? or do I have to do something to allow that in MySQL? As an aside, a recommendation on good beginner and intermediate level MySQL books would be appreciated.

For Unix Review, moodss is "a must-have application for today's network and systems administrators". Moodss won in the Best System Admin Technology category (Tcl Tips and Tricks, Valuable Real World Programming Examples) at the O'Reilly Tcl/Tk 1999 Conference. Linux Magazine calls it a "lifesaver". Tucows gives it 5 stars (cows or penguins :-). Moodss is a modular application. It displays data described and updated in one or more modules, which can be specified in the command line or dynamically loaded or unloaded while the application is running. Data is originally displayed in tables. Graphical viewers (graph, bar, 3D pie charts, ...), summary tables (with current, average, minimum and maximum values) and free text viewers can be created from any number of table cells, originating from any of the displayed viewers. The display area can be extended by adding pages with notebook tabs. Thresholds can be set on any number of cells. Moomps (shipped with moodss) is a monitoring daemon which works using configuration files created by moodss. Thresholds, when crossed, create messages in the system log, and eventually trigger the sending of email alert messages and the execution of user defined scripts. For both moodss and moomps, it is also possible to use a database as a storage mean, so that data history is for example available for presentations and graphs, via commonly available spreadsheet software. Specific modules can easily be developed in the Tcl, Perl and Python scripting languages or in C. A thorough and intuitive drag'n'drop scheme is used for most viewer editing tasks: creation, modification, type mutation, destruction, ... and thresholds creation. Table rows can be sorted in increasing or decreasing order by clicking on column titles. The current configuration (modules, tables and viewers geometry, ...) can be saved in a file at any time, and later loaded at the user's convenience, thus achieving a dashboard functionality. The module code is the link between the moodss core and the data to be displayed. All the specific code is kept in the module package. Since module data access is entirely customizable (through C code, Tcl, Perl, Python, HTTP, ...) and since several modules can be loaded at once, applications for moodss become limitless. Many modules are provided, such as a comprehensive set for Linux system monitoring, MySQL, network, SNMP, Python and Perl modules examples. For example, thoroughly monitor a dynamic web server on a single dashboard with graphs, using the Apache, MySQL, ODBC, cpustats, memstats, ... modules. If you have replicated servers, dynamically add them to your view, even load the snmp module on the fly and let your imagination take over... Thorough help is provided through menus, widget tips, a message area, a module help window and a global help window with a complete HTML documentation. Moodss is multi-lingual thanks to Tcl internationalization capabilities. So far only English and partially French are supported. Help with other languages will be very warmly welcomed. Development of moodss is continuing and as more features are added in future versions, backward module code compatibility will be maintained. ### you may find it now at my homepage: http://jfon
