I am connecting to MySql 3.23(innodb) with

committed changes through JDBC client. Does anyone know about this
issue?
...
The isolation level of READ_COMMITTED has no effect currently in MySQL,
unless you're using BDB tables...InnoDB runs either as REPEATABLE_READ
or SERIALIZABLE, and converts everthing else to REPEATABLE_READ, because
it can do REPATABLE_READ as fast (or faster) than most other DB's
READ_COMMITTED.
I have to correct that BDB always runs at the SERIALIZABLE isolation level.
The default for InnoDB is REPEATABLE READ, and you can enhance it to
SERIALIZABLE with the
SET [GLOBAL | SESSION] TRANSACTION ISOLATION LEVEL
{ READ UNCOMMITTED | READ COMMITTED | REPEATABLE READ | SERIALIZABLE }
SQL command. Since MyISAM uses table locking, we can say that MyISAM always
runs at the SERIALIZABLE level.
The command SHOW VARIABLES currently shows the MySQL default isolation level
as READ-COMMITTED, but it has no effect on any of the table handlers.
Version 4.0.5 will probably feature a new InnoDB isolation level READ
COMMITTED. I will probably at the same time change the MySQL default
isolation level to REPEATABLE READ. You can then lower the InnoDB isolation
level by the command
SET [GLOBAL | SESSION] TRANSACTION ISOLATION LEVEL ...
Users porting from Oracle and other databases will find READ COMMITTED a
useful level.

Bug at GRANT statement?
Hi, When one is doing a GRANT statement at the database level the database name is stored in mysql.db in lowercase letters only, regardless of the upper/lowercase characters used for the database name at the GRANT statement. Example: GRANT SELECT ON SYSMON.* TO theUser@% results in having stored the database name SYSMON as sysmon at mysql.db, column db. GRANT SELECT ON SysMon.* TO theUser@% will grant the privilege to the same database sysmon as the statement above. On a Unix plattform there can be two different databases SYSMON and SysMon! Furthermore, if one manually changes the database name back to the original name - SYSMON - at the column mentioned above and re-run the statement there is a second entry generated in mysql.db: the old one having SYSMON and the new one having sysmon as database name. As the database name is case-sensitive in Unix systems this is critical. I'm running on Win XP, and found this behavior in mysql-MAX NT versions 4.0.2 to 4.0.4. Is this a Bug or intended behaviour?

ANNOUNCE: moodss-16.6 and moomps-2.0
### CHANGES ### --- version 16.6 --- - moomps version 2.0: implemented data cells history feature where cell values are stored in a database (MySQL or PostgreSQL via ODBC) over time, so that for example, common spreadsheet software can be used for presentations, ... - added Edit/Database menu - wrote UNIX manual pages for both moodss and moomps - added support for 3.23.52 and 4.0.4 MySQL server versions in mystatus, myvars and myerrorlog modules - improved internal package management so that modules with a name identical to another package (such as log from tcllib) can still be dynamically loaded - ps module could sometimes initially fail because of an internal divide by zero bug - mounts module now really works from Windows - uses scwoop widget library version 4.1 - removed myquery modules from windows distribution (use existing odbcquery) - successfully tested with Tcl/Tk 8.4.0 ### README ### This is moodss (Modular Object Oriented Dynamic SpreadSheet) version 16.6. 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. 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. 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... Along with a core trace module, arp, cpustats, diskstats, interrupts, kernmods, log, memstats, minimal, mounts, netdev, pci, ps, random, route, sensors, system modules for Linux, MySQL (myerrorlog, myhealth, myprocs, myquery, myreplication, mystatus, myvars), odbcquery, ping, snmp, snmptrap for UNIX, apache and apachex, Minimal and Random Perl modules, minipy and randpy Python modules are included. Running wish moodss ps cpustats memstats mimics the top application with a graphic edge and remote monitoring capability. 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-langual 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. I cannot thank the authors of the tkTable, BLT, MIME/SMTP and the HTML libraries enough for their great work. In order to run moodss, you need to install the following packages (unless you can use the rpm utility, see below): Tcl/Tk 8.3.1 or above, at (or at a mirror near you) http://dev.scriptics.com/ or ftp://ftp.scriptics.com/ the latest tkTable widget library at: http://tktable.sourceforge.net/ the latest BLT library at: ftp://tcltk.sourceforge.net/pub/tcltk/blt/ eventually the latest tclperl library for writing modules in Perl, or the latest tclpython library for writing modules in Python at: http://jfontain.free.fr/ (see the INSTALL file for complete instructions, for UNIX and also Windows platforms).

Hi I've been using mysql for a couple of years now, and until now had no real need of transactions. The could list recommend BDB or InnoDB to implement transatcions. On a small system, which one is faster, and handles load better ? Do they both offer foreign key constraints ? Do they fix the enum() field validation feature ?

re: 3.23.52 log rotation crash
On Mon, 2002-10-07 at 17:40, Victoria Reznichenko wrote: MJF One of the machines is simultaneously slave to one server and master to MJF two others; on that machine, if a RESET MASTER or PURGE MASTER LOGS MJF is executed while its slave thread is performing a query, mysqld MJF reproducibly dies. I also saw the similar bug report, but I couldn't repeat it. Could you test it with our binaries? As mentioned, the original crash was observed with the stock Solaris 8 3.23.52-Max binary. The result was the same, just without a gdb-able backtrace. Just to confuse matters, I put the install back to 3.23.42 and could still make it fall over with a stream of INSERTs (just input from a local client and not even the slave thread) and a RESET MASTER concurrently. So, either we've been living very, very luckily for about a year, or this is a problem specific to Solaris 8. (The old installation, which suffered from a number of bugs but never this one, was Sol7/3.23.42) My job is currently to fix this, so I'll try to spread some test cases around a selection of machines to find more information.

date_add function
Hi I hope I am not being lazy here. I want to use the SQL date_add function on a value from one of my column values but I can't seem to figure out the syntax. This works: select 2002-10-08 09:35:10 + interval 7 hour; but how do I change 2002-10-08 09:35:10 to current_date or feed the values from one (or 2) fields. Ideally I just want the return the time +7 hours. What would also help out is if someone can explain if there is a general rule for using literal strings and column values? Thanx.

Connexion to mySQL failure : error 10060
Greetings, I just installed mySQL Server 3.25.52 on my internet connected PC ( which makes Internet gateway via Internet Connexion Sharing ) using Win98SE. I have created a VB program which attacks the mySQL Server using ODBC. Over LAN and Localhost, everything works just fine. I am trying to reach the mySQL Server on another machine via Internet using the Configuration Panel ODBC Drivers DSN utility but I get this error : mySQL : cant connect to mySQL server '123.456.789.123' (10060) Remote user for this client computer was created on the Server using : GRANT ALL PRIVILEGES ON *.* TO soemone@% IDENTIFIED BY 'somepass'; and everything should work... but does not !!! ( worked over LAN ) Remarks : when I try to reach the mySQL server using Telnet + ServerIP + ServerPort ( 3306 ), I get the server's version ( 3.25.52 ) whilst on the LAN. When I do the same on the Client computer over Internet, I cannot get a response from the server despite the fact that ping works fine between the machines... Did I get something wrong ? Could this be the Internet Connexion Sharing translation which provokes this error ? PS : I do not use any Antivirus program and all firewalls have been stopped while testing in course !

AW: Bug at GRANT statement?
Veronica, That's maybe true, I'll check it. As it's the default setting on Windows and I've never changed it I guess it's on. If the flag lower_case_table_names is turned on, I would expect that SHOW DATABASES os SHOW TABLES is returning lowercase-only names as well? I do get back the exact database and table names as the files in the DATA directory are named, including full upper/lowercases, thus I do get back the name as originally specified when creating the database / table. The manual says (including LOOKUP queries): 8=== If lower_case_table_names is 1 MySQL will convert all table names to lowercase on storage and lookup. (From version 4.0.2, this option also applies to database names.) ===8 Thanks!

startup on win2000 as service not working.
Hi everyone, I have recently moved my mysql server from a win98 machine to a win2000 machine. After running the self extracting setup for mysql, I copied my existing my.ini file over from the win 98 box, made neccesary changes to start mysqld-max-nt from correct dir, I copied the my.ini file because of the Innodb settings I had setup on the win98 machine. I then copied over my Ibdata, and IbLogs directories and their contents to the win2000 box, and the replaced the data directory with the one from the 98 box. I then started mysql from the command prompt with mysqld-max-nt --console it said ...Innodb: Flushing modified pages from the buffer pool... Innodb: Started Ready for connections... And all works fine, however when I restarted the pc, and winmysqladmin.exe was started as a service, the server is not started, I get the red light and no server, or table information. If I then go and start it through the console and run winmysqladmin.exe All my information appears like normal. Can anyone suggest what I should do? Thanks alot, Steve. - 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?

Can somebody point me to a resource on complicated multi-table select statements?

CHAR vs. VARCHAR
After reading the mysql documentation, I am not sure to get correctly the pros and cons of the VARCHAR type. My understanding is that it is useful when a text field has a length that may vary a lot. For example I am thinking using it for a description field where users will put nothing or a small text (for example cf protocol 43) or a bigger text. Am I right in my understanding? If yes, Is it right that using VARCHAR(255) has no influence on the database size? I mean let said that users never use more than 128 chars, would have defined the field as VARCHAR(129) be better? What are the disadvantages of using VARCHAR instead of CHAR. Is it going to be considerably slower? Also, If I want to allow users to add an optional comment for each entry of a table, is it reasonnable to use a VARCHAR so that only one byte is used when no comment are added? or should I create another table to store the comments only when defined by the user?

Re: Resubmit: How to Print field(s) to Printer ??
* tmb I'm Running RedHat Linux 7.3 - Apache - MySQL scripting with PHP on an Intel box... Question 1: I want to print a specified field or fields, in specified records of an mysql db to the line printer several times a day... OK, let's see if we can break this down into smaller tasks: 1) You want specified field/fields from specified records... 2) ...sent to the printer 3) ...several times a day The details: 1) To get data from a mysql database, you use the SELECT statement: URL: http://www.mysql.com/doc/en/SELECT.html 2) To send data to a printer in a Linux environment, take a look at the 'lp' utility by entering 'man lp' on the linux command line. 3) To do this periodically, you can use the cron facility of your linux system, see 'man cron'. Can anyone get me started on the PHP script to do this? Are you sure you want to use PHP for this? PHP is very well suited for making web pages, but not so good for tasks like this... anyway, to get you started with PHP and mysql: URL: http://www.php.net/manual/en/ref.mysql.php Question 2: Is there a better place to post PHP MySQL questions? This list is for mysql questions, but even if your question is mostly PHP related many of the users on this list will be able to help you. Of course, if it is not related to mysql at all, you should not post it to this list. If there is a better place to post PHP MySQL qustions, I don't know. -- Roger - 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?

If I then go and start it through the console and run winmysqladmin.exe All my information appears like normal. Can anyone suggest what I should do? Hi, Run mysqld-max-nt --install first in order to install your new MySQL as a service. Then it should work, at least you should be able to start the service by entering 'net start mysql'.

Re: .Optimize mySQL memory usage ? 41MB threads??
Jon, So how do I optimize memory usage? Where to start ? If your server is compiled with debug=full, the command mysqladmin proc stat shows you total server memory use. Look in the manual at How MySQL uses Memory SHOW VARIABLES (for all vars that control server memory use) Perhaps the following little vignette we worked up may help ... The size of the non-InnoDB index buffer is set by key_buffer_size, which to improve performance for even moderately sized databases can be set to a value up to a quarter or more of available server RAM, but to avoid thrashing, should be set to not more than half. The FIFO table handler cache allots up to 64 entries on a per-open-table-per-connection basis. Issuing mysqladmin flush-tables closes all tables that are not in use, marks all other tables for closing when the corresponding thread ends, and frees most allocated memory. The maximum number of concurrent connections is set by max_connections. Each connection - uses a stack of thread_stack bytes, default 64k, - uses a connection buffer of net_buffer_length bytes, default 16k, - uses a result buffer (same size), and - opens each data and index file once, creating for each table a table buffer, buffers for each column, a row buffer 3 times the maximum row length, and if the table has a BLOB column then a BLOB buffer up to the size of the largest BLOB value. So suppose you expect ... - 200 maximum connections, - queries that access 10 tables max + 3 temp tables each, - average table buffer sizes of 32k, - average row lengths of 10k, - no BLOB columns, and - a quarter of all queries requiring sorts, then - the average number of open tables for all threads, (the MySQL variable table_cache) is 200(10 + 3) = 2600, - the server needs 2600*(64+16+16+3*10+32)k + 50(200/4)MB = 510 MB RAM for connection buffering.

RE: problem with Linux
Last time I saw this error, it was due to an authentication issue. Try
adding the user you have for the JSP pages or the user who is used for
Apache to your domain controller or to the administrative user list
under the NT users dialog. If you add this to the domain controller
make sure Passwords match. If you add the user to your domain
controller you will need to add the user to the local system group for
administration.
I don't know if this will fix the issue, however it should be a
direction to go in.

You're using a _very_ old version of MM.MySQL that is not compatible
with newer versions of MySQL.
Please upgrade to something newer, like MySQL Connector/J 2.0.14 from
http://www.mysql.com/products/connector-j/
You also might want to look into the search functionality at
lists.mysql.com (click on the mailing list name) before asking

You need to Install MySQL as a service.

Re: CHAR vs. VARCHAR
VARCHAR basically sets a maximum length for the field and only stores the data that is entered into it, thus saving on space. The CHAR type has a fixed length, so if you set CHAR(100), 100 character worth of space will be used regardless of what the contents are. The only time you will gain a speed advantage is if you have no variable length fields in your record (varchar, text, etc.). You may notice that all your CHAR fields are changed to VARCHAR as soon as a variable length field type is added. CHAR is less efficient from a space storage point of view, but more efficient for searching and adding. It's faster because the database only has to read an offset value to get a record rather than reading parts until it finds the end of a record. Also, fixed length records will minimize fragmentation since deleted record space can be reused for new records. I always try to create fixed length records, sticking to CHAR types. I try to split out TEXT types into a separate table, although occasionally (rarely) it's not worth the extra coding effort. Hope that helps a bit. I didn't go into all the +/- off each field type, but I think those are the biggest ones.

Are you sure? :-)
As I pointed out, if the first query only gives one row and the second
query gives 7 rows, its an odd duplication of data to request the first
set alongside the second set. At any rate, try the SQL QUERY SELECTs I
recommended to see what results you get first. A contrived example,
with PHP (which would look a lot better if the list allowed the odd HTML
message to go through):
?php
$result = query(SELECT * FROM Products WHERE ...);
// Only one result ...
$row = mysql_fetch_array($result);
?
H2Product: ?php echo $row[Name]; ?, Description: ?php echo
$row[Desc]; ?/H2
?php
$result = query(SELECT * FROM ProductInfo WHERE ...);
// Multiple results ...
while ($row = mysql_fetch_array($result))
{

RE: transaction isolation level
Thanks for all your help. Then it's more confusing to me. I opened two MySql windows
and set autocommit=0 and then update one column and then issue the command COMMIT in
one window, in the other MySql window, I queried the column and saw the change
immediately.
I also did the same thing with one MySql window and one JDBC client(my testcase), and
the testcase can see the change immediately.
In either case, instead of issuing COMMIT, if I issue ROLLBACK, the change will be
rolled back. (Just to make sure the auto commit is not on).
Here is my testcase:
import java.sql.*;
import java.util.Properties;
import com.mysql.jdbc.Driver;
public class TestMySql {
public static void main(String[] args) throws Exception {
Driver.class.getName();
Properties props = new Properties();
props.setProperty(user, root);
props.setProperty(password, geneva);
Connection conn = DriverManager.getConnection(jdbc:mysql://localhost/test,
props);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(select * from testtable);
while(rs.next()) {
System.out.println(rs.getInt(1));
}
System.out.println(Please update the table TESTTABLE...);
System.in.read();
rs = stmt.executeQuery(select * from testtable);
while(rs.next()) {
System.out.println(rs.getInt(1));
}
}

The isolation level of READ_COMMITTED has no effect currently in MySQL,
unless you're using BDB tables...InnoDB runs either as REPEATABLE_READ
or SERIALIZABLE, and converts everthing else to REPEATABLE_READ, because
it can do REPATABLE_READ as fast (or faster) than most other DB's
READ_COMMITTED.
I have to correct that BDB always runs at the SERIALIZABLE isolation level.
The default for InnoDB is REPEATABLE READ, and you can enhance it to
SERIALIZABLE with the
SET [GLOBAL | SESSION] TRANSACTION ISOLATION LEVEL
{ READ UNCOMMITTED | READ COMMITTED | REPEATABLE READ | SERIALIZABLE }
SQL command. Since MyISAM uses table locking, we can say that MyISAM always
runs at the SERIALIZABLE level.
The command SHOW VARIABLES currently shows the MySQL default isolation level
as READ-COMMITTED, but it has no effect on any of the table handlers.
Version 4.0.5 will probably feature a new InnoDB isolation level READ
COMMITTED. I will probably at the same time change the MySQL default
isolation level to REPEATABLE READ. You can then lower the InnoDB isolation
level by the command
SET [GLOBAL | SESSION] TRANSACTION ISOLATION LEVEL ...
Users porting from Oracle and other databases will find READ COMMITTED a
useful level.

Query Spans Multiple Pages
Hello All. I hope you are all having a great day. ;) I am trying to query MySQL using PHP and I would like the results to display on multiple pages. I would like to display only 20 results per page and allow the user access to the other pages by clicking next or an index of numbers 1 2 3 4 5 6 and so on dependent upon the number of results returned. I do not know how to do this?? Can anyone point me in the right direction??? Also, When a user does perform this query, will all of the pages be created at that time. Or will the page be created with another request and response from the server. In other words. Does the result of the query get stored in a variable that is accessed on the client machine or does the php code return the limit per page and provide a link which acts as another query to display the next page of results. Thanks in advance.

RE: HA of MySQL
On Mon, 2002-10-07 at 22:02, Jeremy Tinley wrote: The problem isn't so much with the failover. It's with data integrity. Binlogs control replication. You can place a failover master in between the master and slaves. In the event of a master failure, you eliminate the loss of writes by directing them to the failover. If you lose your failover, the binlogs can be completely different thus pointing the slaves to the master is useless. The binlog position is the real problem. Since binlogs are stored with their byte position as the indicator instead of a unique value passed on from the master, there's no easy way of finding the position you were just at. Is is possible to write two binlogs? One to the local disk, one to a network device? If you set up your failover to log-slave-updates, then this will maintain a fairly up to date copy of your binlogs. There is a risk that if one update takes a very long time, then the master might get a long way ahead while the slave replicates this query, but generally as long as updates are short, this should provide a reasonably secure remote copy of the contents of your binlog. The next problem is that there is no way to synchronise the log position on the failover with that on the master. What you can do however, is periodically stop replication on the failover and snapshot the two log positions, eg: slave stop; show slave status; # for Pm show master status; # for Pf slave start; The slave and master positions give you a reasonable chance of doing the arithmetic required to resync all your slaves to the failover if the master fails. Eg: Psf = Psm + (Pf - Pm) where Psf is Position of slave relative to failover, Psm is Position of slave relative to master, Pm is a recorded master position, and Pf is the corresponding slave position of the failover. The arithmetic gets a bit hairy around rotations of the binlogs, compounded by mysql sometimes inserting extra markers in the binlog when rotations occur, and sometimes not. So, the more often snapshots are made of the positions, the better. Anyhow, there's another 2 cents... == Martin - 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?

Performance of a sequence many indexed queries
I have a database with a table called targetTsObj, and I want to perform many queries from it, such as this one: select run,rerun,camcol,field,id,ra,decl,r from targetTsObj where ra between 255.84730673785904 and 256.31969326214096 and decl between 58.7494108 and 58.9577892 One of these returns a few hundred records from the 1.2 million records in the table. This query returns in under a second. However, after 40 or so of these queries, the time per query is up to 30 seconds or so. Is this perfomance as expected, or is there something I can do? Build the indices differently? A setting in my.cnf? The machine is running Linux, with 1 GB or ram, MySQL server version 3.23.49 Thanks! === I send the queries with a client program, using these C api's: mysql_real_connect(mysql, host, user, passwd, db, port, unix_socket, client_flag); mysql_query(mysql, query); mysql_store_result(mysql); In a loop, until all rows are fetched: field = mysql_fetch_fields(mysql_res); And after getting all the rows for a query: mysql_free_result(mysql_res); Here is the result of the show index command: mysql show index from targetTsObj; +-++--+--+-+---+-+--++-+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Comment | +-++--+--+-+---+-+--++-+ | targetTsObj | 1 | objId|1 | objId | A | 1228983 | NULL | NULL | | | targetTsObj | 1 | fieldId |1 | fieldId | A |1985 | NULL | NULL | | | targetTsObj | 1 | ra |1 | ra | A | 1228983 | NULL | NULL | | | targetTsObj | 1 | decl |1 | decl| A | 1228983 | NULL | NULL | | | targetTsObj | 1 | u|1 | u | A | 111725 | NULL | NULL | | | targetTsObj | 1 | g|1 | g | A | 122898 | NULL | NULL | | | targetTsObj | 1 | r|1 | r | A | 122898 | NULL | NULL | | | targetTsObj | 1 | i|1 | i | A | 122898 | NULL | NULL | | | targetTsObj | 1 | z|1 | z | A | 111725 | NULL | NULL | | | targetTsObj | 1 | ug |1 | u | A | 111725 | NULL | NULL | | | targetTsObj | 1 | ug |2 | g | A | 1228983 | NULL | NULL | | | targetTsObj | 1 | gr |1 | g | A | 122898 | NULL | NULL | | | targetTsObj | 1 | gr |2 | r | A | 1228983 | NULL | NULL | | | targetTsObj | 1 | ri |1 | r | A | 122898 | NULL | NULL | | | targetTsObj | 1 | ri |2 | i | A | 1228983 | NULL | NULL | | | targetTsObj | 1 | iz |1 | i | A | 122898 | NULL | NULL | | | targetTsObj | 1 | iz |2 | z | A | 1228983 | NULL | NULL | | +-++--+--+-+---+-+--++-+ 17 rows in set (0.00 sec) Finally, here is /etc/my.cnf: bash-2.04$ more /etc/my.cnf [mysqld] set-variable = key_buffer_size=512M set-variable = table_cache=512 set-variable = query_buffer_size=20M # set-variable = sort_buffer=100M # set-variable = read_buffer_size=100M datadir=/export/data/dp20.a/data/mysql socket=/var/lib/mysql/mysql.sock [mysql.server] user=mysql basedir=/var/lib [safe_mysqld] err-log=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid - 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: transaction isolation level
Jianliang,
I tested that with two mysql clients, and it appeared to work ok. Check with
SHOW CREATE TABLE tablename
what is the type of your table. Is it MyISAM?
Also put the line
log
to the [mysqld] section of your my.cnf and restart mysqld. Then you will see
all received queries in the file 'hostname'.log in your datadir. Check from
it what SQL queries your clients actually send to the mysqld server.

Thanks for all your help. Then it's more confusing to me. I opened two MySql

The isolation level of READ_COMMITTED has no effect currently in MySQL,
unless you're using BDB tables...InnoDB runs either as REPEATABLE_READ
or SERIALIZABLE, and converts everthing else to REPEATABLE_READ, because
it can do REPATABLE_READ as fast (or faster) than most other DB's
READ_COMMITTED.
I have to correct that BDB always runs at the SERIALIZABLE isolation level.
The default for InnoDB is REPEATABLE READ, and you can enhance it to

RE: transaction isolation level
Thanks Heikki,
My testcase is not valid. After I get the connection, I didn't set auto commit to
false on the connection object, so I was unable to see the committed data. I saw the
REPEATABLE READ behavior now, but it's unfortunate to know READ COMMITTED is not
supported yet...

MySQL on QNX anyone?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, we've started doing some work of porting MySQL 4.0 to the QNX operating system. The patches are already part of the source tree and MySQL currently compiles and runs, but we have not done any thorough testing yet. One of the known bugs is that mysqld currently does not create a socket file, so you can only access it via TCP/IP. If you are interested in running MySQL on QNX, please get in contact with me directly! We currently would appreciate any feedback on this topic.

Re: Getting Fields from a sql table
Hello everyone, Can someone please tell me how I can do the following: From the query below, I want to get the details of the header of the message and display them on a page, one per line. If I just query the Header field, it displays them in one long line. What can I do to display the them one per filed? [snip] I may be missing something, but it seems that all your code is doing is creating a very long string out of all the header information. If you want each piece on a 'new line' then you will have to add a 'newline' character yourself between each piece of the string.

Binary data dumps?
I've been using MySQL now for around a month. I also administer the system where our MySQL implementation is installed. Each night, we perform a full file system backup around 11:50PM. I just noticed that our MySQL root data directory is filling up with binary data files named so: `hostname`-bin.### So, for instance (our hostname is 'dewey'), I saw the following being deposited into our MySQL data dir: -rw-rw1 root root14909 Oct 7 23:50 dewey-bin.035 There are now 35 of these files sitting in the data dir, some of which take up an enormous amount of disk space. Are these data dumps of some sort? Does this happen every time MySQL shuts down? Should I be concerned about this? Should I save these files or delete them? I've checked the logs and MySQL seems to be shutting down just fine (no errors). However, these files are quickly eating away my disk space. A couple of them are over 500MB in size! If any one has any advice or information it would be appreciated.

I'm setting up MySQL on a small ISP and would like to be able to restrict the size of individual databases to something like 25M. What's the best way of getting this done? The server is running Solaris, if it's necessary to do it through the OS insteady of through MySQL. Hi, Unfortunately you'll have to use Solaris disk quotas for that. Make sure that the table files of each restricted-space user count towards their personal quotas. This means that you have to create a separate OS account for each user you want to restrict with the quota. This also means that the table files must be owned by those restricted users. I hope this quota feature will be added into MySQL in the future.

Re: How to install INNODb in Windows 2000 server
If you want to stay with 3.23 then download the max version. Install the max version. Look at one of the .cnf files in the main mysql directory. Uncomment the lines having to do with innodb. Change the innodb_data_home_dir variable to be the path you want d:\mysql for instance. When you are done with the .cnf file rename it to my.cnf and put it in c:\mysql\data. Restart the server and you should be able to set up innodb tables. NOTE: I am currently using 4.0.4 pro and it loads up with Innodb by default. If you have any further questions please don't hesitate to ask.

Re: CHAR vs. VARCHAR (fork)
The only time you will gain a speed advantage is if you have no variable length fields in your record (varchar, text, etc.). You may notice that all your CHAR fields are changed to VARCHAR as soon as a variable length field type is added. CHAR is less efficient from a space storage point On that note, I've often wanted to be able to do something along the lines of: ALTER TABLE foo USE CHAR; ALTER TABLE foo USE VARCHAR; ... and just port the current max-length values between the two, while changing all relevant columns. -- Michael T.

What's the largest file your operating system will let you create? Is your answer related to the index size meaning that it is limited by the OS capability? I saw somewhere that it is limited to 4 Gig (MySQL 3.29) is it possible to do replication with a master on linux and a slave on windows? Yes. if yes, how can I make the slave work on linux if the master crashes? I'm not sure what you mean. Can you be more specific? Suppose the master file becomes corrupted (linux), can we recover the file from the slave (That is, from the Windows OS)? thanks David Jeremy -- Jeremy D.

MySQL install Problem?
I have am having problems getting the MySQL server to start running, please help me, here are my problems, I have also displayed my error logs below, at least I hope they are the error logs; I have been trying to install the mysql-3.23.52-pc-linux-gnu-i686.tar.gz Everything seems to be going smoothly until I entered the command ./scripts/mysql_install_db I got this output which i believe is ok; cords-orj86jfje:/usr/local/mysql/mysql # ./scripts/mysql_install_db Preparing db table Preparing host table Preparing user table Preparing func table Preparing tables_priv table Preparing columns_priv table Installing all prepared tables 021007 18:15:39 ./bin/mysqld: Shutdown Complete To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! This is done with: ./bin/mysqladmin -u root password 'new-password' ./bin/mysqladmin -u root -h cords-orj86jfje password 'new-password' See the manual for more instructions. You can start the MySQL daemon with: cd . ; ./bin/safe_mysqld You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory: cd sql-bench ; run-all-tests Please report any problems with the ./bin/mysqlbug script! The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at https://order.mysql.com Then I try to enter this command to configure my passwords; Firstly cords-orj86jfje:/usr/local/mysql/mysql # ./bin/safe_mysqld --user=mysql [1] 1346 cords-orj86jfje:/usr/local/mysql/mysql # Starting mysqld daemon with databases from /usr/local/mysql/mysql/data 021007 19:15:21 mysqld ended [1]+ Done./bin/safe_mysqld --user=mysql THEN, cords-orj86jfje:/usr/local/mysql/mysql # ./bin/mysqladmin -u root password sqlpass ./bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)' OR cords-orj86jfje:/usr/local/mysql/mysql # ./bin/mysqladmin -u root sqlpass ./bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)' Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
