Hi, a question about mysql and servlets
Hello everyboy, nice to post you. I hope this question not to be very frequent but i'm new in this list. I'd like to know if anybody knows how to connect a servlet with MySQL. It doesn't matter if it is by a ODBC:JDBC bridge o a 100% JDBC Driver. I can download the drivers. I want to know the steps and the string connection to use. If you are so so so so kind and the driver u use is not big , plese post it. Thank's from a new MySQL user. Francisco Glvez Martnez [EMAIL PROTECTED] [EMAIL PROTECTED] --- Chatea con Isabel Pisano.

Communication Errors
Hi ! I've just upgraded to the new mysql server 3.23.32 and in the log I now see 'Aborted connection ... (Got an error reading communication packets)'. I have found information about this problem such as using the binary release instead of the source release. I have now done this and it still appears in the log, the last thing it suggested was to check the patch level of Solaris. I am running on a Sun Solaris 2.7 machine, does anybody know what the recommended patch level is to stop this problem happening ? Thanks.

Erratic behaviour of binary varchar fields
Description. The bug is about selecting binary varchar fields and consists in erratic behaviour of these fields in combination with OR. When executing a SELECT statement with an ORed WHERE-clause such that the two basic clauses each select a differently cased variant of one (binary varchar) term, only the first is returned, although both are in the table. The funny thing is that this only holds when you have *two* clauses with one OR. With more ORs, the bug disappears. Concretely: screenshot mysql desc terms; +-+-+--+-+-+---+ | Field | Type| Null | Key | Default | Extra | +-+-+--+-+-+---+ | term| varchar(200) binary | | PRI | | | | corpus_id | decimal(15,0) | | PRI | 0 | | | frequency | decimal(15,0) | | | 0 | | | weight | float | YES | | NULL| | | n_documents | decimal(15,0) | | | 0 | | +-+-+--+-+-+---+ 5 rows in set (0.00 sec) mysql select * from terms where term = 'bank' OR term = 'Bank'; +--+---+---++-+ | term | corpus_id | frequency | weight | n_documents | +--+---+---++-+ | bank | 2 | 128 | NULL | 75 | +--+---+---++-+ 1 row in set (0.00 sec) mysql select * from terms where term = 'Bank' OR term = 'bank'; +--+---+---++-+ | term | corpus_id | frequency | weight | n_documents | +--+---+---++-+ | Bank | 2 | 176 | NULL | 99 | +--+---+---++-+ 1 row in set (0.01 sec) mysql select * from terms where term = 'bank' OR term = 'Bank' OR term = 'banks' or term = 'Banks'; +---+---+---++-+ | term | corpus_id | frequency | weight | n_documents | +---+---+---++-+ | Bank | 2 | 176 | NULL | 99 | | Banks | 2 |18 | NULL | 11 | | bank | 2 | 128 | NULL | 75 | | banks | 2 | 176 | NULL | 66 | +---+---+---++-+ 4 rows in set (0.00 sec) mysql \screenshot (The client on a WinNT machine (mysql Ver 9.37 Distrib 3.22.29, for Win95/Win98 (i586))).

connection lost on long-distance connection
I've ran into some problems when connecting to a mysql server over a long-distance connection (i.e.: the internet). The first time a client reconnects from a idle connection this reconnect fails, only the second time it succeeds. The main problem is that i've written a win32 app that connects to this server. Normally the client and server will be on a LAN but i test the program on a their database from my place. I use libmysql.dll for this. (no odbc!) Normally i relied on libmysql.dll to reconnect when a connection was lost, on a lan this never gave any problem but now it does, giving my app no result set on a particulair query after been idle for a while, and thus introducing bugs. I am able to reproduce this with the standard mysql client. Both the win32 and the linux client behave the same. Tech info: server running mysql 3.23.32 win32 binary distribution Client app is behind a firewall, MySQL server is directly connected to the internet. Telnet or other sessions normally remain alive through my firewall. ping trip-around time: about 200ms, however sometimes loads of packet loss (possible cause?) Just after a connection everything is fine: mysql show processlist; +-+---++--+-+--+---+ --+ | Id | User | Host | db | Command | Time | State | Info | +-+---++--+-+--+---+ --+ | 429 | admin | cx.upc-c.chello.nl | NULL | Query | 0| NULL | show processlist | +-+---++--+-+--+---+ --+ 1 row in set (0.21 sec) Then if a leave the client for a while (say: ten minutes) the connection is gone: mysql show processlist; ERROR 2013: Lost connection to MySQL server during query mysql show processlist; ERROR 2006: MySQL server has gone away No connection. Trying to reconnect... Connection id:430 Current database: *** NONE *** +-+---++--+-+--+---+ --+ | Id | User | Host | db | Command | Time | State | Info | +-+---++--+-+--+---+ --+ | 429 | admin | cx.upc-c.chello.nl | NULL | Sleep | 2732 | | NULL | | 430 | admin | cx.upc-c.chello.nl | NULL | Query | 0| NULL | show processlist | +-+---++--+-+--+---+ --+ 2 rows in set (5.99 sec) So, the server still thinks i've got an active connection. this list keeps on growing. For as far as I can see, my win32 app behaves the same as the mysql client. It'll try to reconnect but it fails, only second time it succesfully reconnects. I ported my app from interbase to mysql. with interbase i did not have this connection problem, but it's so terribly slow on many queries/ larger result sets (interbase fetches a result field by field, generating numerous network packets...) I also have some PHP scripts that connect to this server, running in win32 cgi mode. They do behave normally, i guess because they have to connect every time (i.e.: no persistant connections for win32 w/o isapi) they are called. When not idle (i.e. active querying) everything behaves normal and i notice no errors at all, not even on heavy load.

RE: BDB table corruption when inserting/retrieving a BLOB into a BDB table
We had similar problems with version 3.23.33. For us, the fix was to move
the errant tables to MyISAM. We did not need transaction support for those
tables. We have since moved the tables back to BDB with MySQL version
3.23.34a. The problem seems to have been resolved in this latest update.

We have also experienced the same exact behavior, also using the mm.mysql
driver, on Linux. However, our problem is intermittent. There are times
(though these times cannot be accurately predicted) where the data is
retrieved correctly, which implies that the data is stored correclty. We
have verified that the data is being stored correctly by using mysql to
select the data into a dumpfile. We did not try to recreate the problem
with a table handler other than BDB.

in the real table, most of them work fine but one in particular is all of
the sudden causing problems):
---code snip---
String fn="badblob.txt";// Filename of the blob I'm loading that
causes problems
FileInputStream style_fis=new FileInputStream(fn);
byte[] style_bytes=new byte[style_fis.available()];
style_fis.read(style_bytes);
String dQuery="delete from ttest4";
String iQuery="insert into ttest4(id,ablob) values(1,null);";
conn=cp.getConnection();// Gets a JDBC connection from a pool I
keep elsewhere
Statement stmt=conn.createStatement();
stmt.executeUpdate(dQuery);
stmt.executeUpdate(iQuery);
stmt.close();
String uQuery="update test4 set ablob=? where id=1";
pstmt=conn.prepareStatement(uQuery);
pstmt.setBytes(1,style_bytes);
pstmt.execute();
pstmt.close();
cp.releaseConnection(conn);
---end code snip---
(I've modified this some, but basically my code will insert an empty row
then update it with the blob, this is to deal with some issues we've had
with other RDBMs' implementations of JDBC).
This seems to go just fine.
3) Retrieve that blob with the following code:
--code snip--
conn=cp.getConnection();
Statement stmt=conn.createStatement();
String query="select ablob from ttest4 where id=1";
ResultSet rs=stmt.executeQuery(query);
while(rs.next()) {
Blob b=rs.getBlob(1);
byte[] blobBytes=b.getBytes(0,(int)b.length());
System.out.println(new String(b));
}
--end code snip--
At this point my output ends up very garbled. The output usually starts off
with some very strange ASCII characters (seemingly binary data) with things
like filesystem names thrown in the mix... Then at some point parts of my
actual data (from the "badblob.txt" file in step 2) appears... Then the end
of it is usually overwritten with more strange ASCII characters.
In attempting to fix this problem, I dropped and recreated the entire
database a few times, restarted the server daemon, etc. I finally ended up
changing the table to TYPE=MyISAM and the problem went away. Unfortunately,
I need transaction support for this project.
I've been using this code, data, server version, bdb table, etc for a few
weeks now with no problems, but suddenly when regenerating the schema last
night this started to occur and is now happening regularly.
I'd like to blame this on the particular blob I'm

Trouble automating backup
Hi, I'm trying to write a Perl script that will automate the backing up of
the tables in my database. I'm building an array of the tables in the
database, using show tables, and then I step through the array with a
foreach loop. I've setup the SQL statement (to do the backup) as follows:
$sth_backup = $dbh-prepare("BACKUP table ? TO ?");
And I'm calling it like this:
$sth_backup-execute($table_name, $backup_location)
|| warn "Cant backup table $table_name: $DBI::errstr";
I've tried various values for $backup_location, but I can't seem to get it
to work. When I use 'c:/' I get this:
DBD::mysql::st execute failed: You have an error in your SQL syntax
near ''iteration_failure'
TO 'c:/'' at line 1 at backup_tables.pm line 24
When I use 'c:\' I get this:
Bareword found where operator expected at backup_tables.pm line 18,
near "$sth_tables-execute
() || die "Can't" (Might be a runaway multi-line '' string starting on
line 11)(Missing
operator before t?) String found where operator expected at
backup_tables.pm line 25, near "||
warn "" (Might be a runaway multi-line "" string starting on line 18)
(Missing semicolon on
previous line?)
Anyone have any thoughts on what I need to do to get this to work? Thanks

You cannot embed table names or column names with the
placeholder. If you do, that will not be mapped to
BACKUP table foo
but to
BACKUP table 'foo'
which will most probably fail.
Use
prepare("BACKUP table $table TO $othertable")
instead.

[#Deleted] records in Access
Is anybody aware of a problem when connecting Microsoft Access to MySQL 3.23 where records with AutoIncrement fields claim to be deleted after entry? Here's what I have: MySQL 3.23.32 MyODBC 2.50.36 Microsoft Access 2000 Some of my tables have an AutoIncrement Integer field as the primary key and some have a Char() field as the primary key. The tables with Char() for the primary keys work fine. If I enter a record with AutoIncrement numbers as the primary key, Access claims the record is deleted as soon as it is updated. I do not enter a value for the AutoIncrement field (that would defeat the whole purpose of having and autoincrement field). The record does actually get saved correctly, and refreshing the data shows the newly created record. Also, if I do enter a value for the autoincrement field, it will not have this problem. Is there anything I can do to get this problem fixed? One more thing, in the past, I have used a similar setup with MySQL 3.22.29 for Windows. Everything worked fine with that version, but since it was shareware, I tried to upgrade to the 3.23.xx version under the GPL license. That is when I first ran into this problem, and I see that it still has not been fixed, or has not been reported. Please let me know what I can do to help solve this problem.

Re: Transactions
Ryan, How exactly does the BEGIN/COMMIT/ROLLBACK transaction process work? The examples I have seen are like: BEGIN; statement 1; statement 2; statement n; COMMIT; Does this imply that if any of the statements fail then a ROLLBACK will be called, otherwise it will COMMIT? you have to code the rollback logic in your application. Since you send SQL statements to MySQL one at a time, the MySQL server cannot know what statements are still coming. In your example, MySQL/Innobase would do the following: if any single SQL statement fails, then depending on the error, Innobase will roll back part of the statement, the whole statement, or everything you have done since the last BEGIN (= the whole transaction). Then, if you continue sending statements to MySQL, they will be processed like nothing would have happened to the previous statement. Currently, in MySQL/Innobase a duplicate key error in an insert of a row only rolls back that single row insert. A deadlock with other transactions rolls back the whole transaction. ANSI SQL standard specifies that an error in an SQL statement should result in a rollback of that whole statement. We have to consider in future if MySQL should by default follow the ANSI spec.

In section 12.2.2.1 of the manual it states that MySQL will allow one to move a table and symbolically link it. Then MySQL uses realpath() to find the absolute path. I have done this and all is fine until someone does a DELETE FROM or a ALTER TABLE . When these are done the symbolic links are removed and the tables is recreated in the original database directory. I believe this is because MySQL does a rm on the link. This behavior seems contrary to the use of realpath. Anyone have any idea how to move tables and use links without the above problems ? Thanks.

Failover and Replication
Hi, We are implementing a linux cluster, and rather than get gouged by oracle (in performance and licensing) would much rather use MySQL. I searched through the archives and found several references to failover and replication but still have some questions. If I understand correctly, replication creates a working copy of mysql on another server, but it looks like the algorithm to automatically change slave to master if the master dies will not be added until mysql 4.x (from 11.4 in the manual). Is this still the case? Im not sure when that was written, perhaps there is news on this front? I also did not find a expected release date Does anyone have any stories/suggestions/experiences in regards to rolling our own monitoring script? Thanks!

Working with UltraDev
Hello guys Does anyone ever work with Macromedia Dreamweaver Ultradev 4.0 and MySQL? I've just started a project and would like to work with MySQL on a RH6.2 box. The goal is to have UltraDev easily working on a Windows PC but managing the data bases store on the RH box. I guess I must start by downloading MyODBC, as I'm newbie to this topic, don't know where to get it and if it is its real name.

RE: use one database or many databases
I have a similiar situation where I've got a huge database that maintains data for quite a few clients. Queries have gotten extremely sluggish. What I'm working on right now is to have a control database with a single table that contains a unique identifier for each client and a database name. When they log in it figures out the name of the database to use by looking in this table. Each instance of the program only accesses this one database (after finding it in the control) Since all of the programs that make up the suite call the same routine to establish a connection, it is a fairly painless update that I hope will provide substantial performance increases. The only drawback to this is if you need to run a lot of reports across clients. A few administrative reports wouldn't be so bad, but I wouldn't want to like construct a web page on the fly based on a query accessing 50 different data sources. Since this isn't the case here, it shouldn't be a problem. I'm by no means a guru, but this just seems like a logical way to handle the problem. If there is some major logic flaw here, please let me know now! ;) --James [EMAIL PROTECTED] --- From your message of Wed, 14 Mar 2001 08:26:21 -0600: If all the data will be used by the same application then I would suggest that you stick with a single database.

RE: Full tables...
Hi, The output from mysqladmin variables would be useful. Quentin -Original Message- From: Dave Camarillo [mailto:[EMAIL PROTECTED]] Sent: Thursday, 15 March 2001 7:42 a.m. To: [EMAIL PROTECTED] Subject: Full tables... Hello all, I've run into a minor problem with my schema/mysql. I have a table with 64 columns (varying data-types) and about 7 indexes (some multi-column indexes) containing roughly 19 million records. Were running Solaris 2.8 on Sparc with mysql 3.23.33 with raid-tables and large files compiled in with gcc 2.95.2. In my development, I have roughly 30 MyISAM tables that are identical in columns/indexes to this particular table, the only difference is the number of records in this table (this table has the most records) My problem, is that when I go to do an update statement to the table, I get an error message back from the Perl DBI saying that "The table BLABLABLA is full". I have this table set up with raid-0, across 8 slices, each slice with a max size of 2 gigs. (in theory the max size of the table would be 16 gigs). After looking at the actual table slices in the mysql data directory, the sum of the slices only takes up about 4.5 gigs while, the index file is about 1.5 gigs and only in 1 file. There is plenty of memory on the machine, currently mysql has malloc'ed about 4 gigs. In my code, I've tried putting in "SET SQL_BIG_TABLES=1;", however I still get the same error. What kinds of things cause "Table Full" errors? I've looked through the mysql documentation, however I haven't been able to find a fix that works. Any suggestions, ideas etc? Thanks Dave [EMAIL PROTECTED] Some other info about how mysql is setup: Tmp_table_size=1gig Record buffer = 512M Table cache = 1gig Key_buffer = 1gig (I've been playing around with these settings so I know they are not optimal) Another question, off this subject. The most memory I've seen mysql use is 4 gigs. Is it possible for it to use more? Do I need to compile it with a different memory model? If so, what kind of model and where can I find out more about it. - 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?

One case that comes to mind is when you have a table that you both need to write to often and read from often. If the columns you are reading from and writing two are different, then you can break them out into different tables. This is in-line with a general rule of thumb that a table should be mostly read from or mostly written to, not both equally (as databases have trouble doing both efficiently). Here's an example of a case I had a while back. I had an "Accounts" table which contained username, password, and last-access columns. The username/password fields were read from often, and the last-access column was written to often. So, I broke out the last-access column into its own table. This reduced the load on the Accounts table and thus speeded up access. With "mysqladmin processes" I had been seeing clients waiting for access to the Accounts table while the Last updates were happening. Meanwhile, I actually stopped using UPDATE to change the last-access column in the new Lasts table, instead I now use INSERT DELAYED. I did this because it's my understanding that UPDATEs are slower than INSERTs, plus using DELAYED has its performance benefits as well. This did complicate reading the last-access info, I have to do an "SELECT last-access FROM Lasts ORDER BY last-access DESC LIMIT 1" to get the most recent info. Plus I have a nightly script that cleans-up(deletes) non-latest Lasts rows. But, all this did solve my db performance problem. -bill - 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: Full tables...w/ show variables
Hello again. A few thoughts - nothing certain, and all derived from the fine manual, which you have already read, I'm afraid: Are you issuing the SQL_BIG_TABLES=1 in the same connected session as the query? Is there enough space in '/var/tmp'? However, if that was filling up, mysqld would wait for it to empty, rather than report an error. Are you able try setting the --big-tables option for the server, or increase the 'tmp_table_size' variable? If these lead nowhere, I'll have to leave it to the MySQL guys to figure out.

mysqldump Error
I'm trying to use mysqldump to dump a database (obviously). Here's the commandline I'm using: [root@fugu work]# mysqldump --tab=. wonderdesk mysqldump: Got error: 1: Can't create/write to file '/root/work/Calls.txt' (Errcode: 13) The interesting thing, is that is IS creating Calls.sql, but it then crashes on Calls.txt. I've got plenty of drive space, file permissions aren't a problem, and it's creating some files, but not all of them. Anyone got any Ideas? I've searched around a bit, and haven't been able to find what an errcode 13 is, so I'm out of ideas. Thanks guys! Joel

Re: setting simple mysqld options in /etc/my.cnf
I've found that past versions of MySQL ship with a version of safe_mysqld that reads the config file itself and only passes on a few of the parameters. We had to rewrite our own version to allow mysqld to actually parse the stuff on its own. Note that the my.cnf file that ships often seems to put the error log entry in the [mysqld] section which causes mysqld to stop with an error because it doesn't understand it if you run mysqld directly. I am assuming you are using Linux/Unix here. If it is Windows, I can't help :-) If you are using Linux/Unix, look through safe_mysqld and make sure that it will correctly pass these parameters through to mysqld. We had to make changes to get the logs to work the way we wanted them and eventually wrote our own version. Our version is not publically available, sorry.

Re: use one database or many databases
I've run into a situation where i need to split an enormous database (only say a million rows but oh so long possibly many K) Using JDBC and prepared statements this could be facilitated if we could have the driver implement a setSQL(int x, "--text--") function which could replace a '?' placeholder for the table name in the SQL statement. I can imagine other uses for this too. Unfortunately not a feature in JDBC2.0 or 3.0. Dave.

Each instance of the program only accesses this one database (after finding it in the control) Since all of the programs that make up the suite call the same routine to establish a connection, it is a fairly painless update that I hope will provide substantial performance increases. The only drawback to this is if you need to run a lot of reports across clients.

Re: mysqldump Error
ahhh.. ok, I understand.. So the moral of the story is the mysql process itself touches the local filesystem. It's NOT the UID of the person running the command that matters, it's who the daemon is running as. Hence the reason the help page says "this only works when running on the same machine the daemon is on." But, I imagine the first part of the export IS running as root, because it works. Thank you for clearing this up, that didn't make a whole lot of sense to me, not it makes perfect sense. The export works now, case closed.. Thanks again!

MySql connection failed in browser
Hey everyone, I just went through a new setup of Information Resource Manager scripts under PHP 4.0.1p12-9 that work with MySql 3.23.22-6 under Apache 1.3.125-25, all of this stuff except the Resource Manager come standard with RedHat 7.0. After creating the database for the set of php scripts, I should be able to go right into my web browser and get to the scripts and see all the default screens. I can get to the login screen, but when entering a username and password I get the following: Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in ./irm.inc on line 83 Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in ./irm.inc on line 84 Warning: MySQL: A link to the server could not be established in ./irm.inc on line 84 It just looks like there may be a problem with the php scripts and the link to the mysql database, I've been through all of the config files I could find and have been searching the internet for some type of answer.

connection lost on long-distance connection
I've ran into some problems when connecting to a mysql server over a long-distance connection (i.e.: the internet). The first time a client reconnects from a idle connection this reconnect fails, only the second time it succeeds. The main problem is that i've written a win32 app that connects to this server. Normally the client and server will be on a LAN but i test the program on a their database from my place. I use libmysql.dll for this. (no odbc!) Normally i relied on libmysql.dll to reconnect when a connection was lost, on a lan this never gave any problem but now it does, giving my app no result set on a particulair query after been idle for a while, and thus introducing bugs. I am able to reproduce this with the standard mysql client. Both the win32 and the linux client behave the same. Tech info: server running mysql 3.23.32 win32 binary distribution Client app is behind a firewall, MySQL server is directly connected to the internet. Telnet or other sessions normally remain alive through my firewall. ping trip-around time: about 200ms, however sometimes loads of packet loss (possible cause?) Just after a connection everything is fine: mysql show processlist; +-+---++--+-+--+---+ --+ | Id | User | Host | db | Command | Time | State |Info | +-+---++--+-+--+---+ --+ | 429 | admin | cx.upc-c.chello.nl | NULL | Query | 0| NULL |show processlist | +-+---++--+-+--+---+ --+ 1 row in set (0.21 sec) Then if a leave the client for a while (say: ten minutes) the connection is gone: mysql show processlist; ERROR 2013: Lost connection to MySQL server during query mysql show processlist; ERROR 2006: MySQL server has gone away No connection. Trying to reconnect... Connection id:430 Current database: *** NONE *** +-+---++--+-+--+---+ --+ | Id | User | Host | db | Command | Time | State |Info | +-+---++--+-+--+---+ --+ | 429 | admin | cx.upc-c.chello.nl | NULL | Sleep | 2732 | |NULL | | 430 | admin | cx.upc-c.chello.nl | NULL | Query | 0| NULL |show processlist | +-+---++--+-+--+---+ --+ 2 rows in set (5.99 sec) So, the server still thinks i've got an active connection. this list keeps on growing. For as far as I can see, my win32 app behaves the same as the mysql client. It'll try to reconnect but it fails, only second time it succesfully reconnects. I ported my app from interbase to mysql. with interbase i did not have this connection problem, but it's so terribly slow on many queries/ larger result sets (interbase fetches a result field by field, generating numerous network packets...) I also have some PHP scripts that connect to this server, running in win32 cgi mode. They do behave normally, i guess because they have to connect every time (i.e.: no persistant connections for win32 w/o isapi) they are called. When not idle (i.e. active querying) everything behaves normal and i notice no errors at all, not even on heavy load. Any ideas / solution would be really appreciated thanx in advance, rene - 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: MySql connection failed in browser
Since you say you're new to this stuff, let's start with the very basics. RH7.0, I thought, was done poorly with many bugs. You can download their latest RPM patches from their ftp server which will fix up a lot of these bugs. With MySQL, my advice is to download the latest and greatest RPM directly from their website, not RH's. If you're not going to bother upgrading PHP then don't bother using persistent connections. The next step, once installed/upgraded, check that the server is working ok.

Re: am I alone? (scale)
We've had fairly bad luck with Linux 2.2.X and SMP for any kind of high-end system. The DAC 960 SCSI controllers proved to be fairly problematic in this environment. Sometimes updating the drivers helps. We have a couple of systems that run much better when we do not use one of the CPUs. Just to offer another data point, we've had great luck with SMP Linux 2.2.x and the DAC 960 controller (a Mylex AcceleRAID 352). Debian Potato Linux 2.2.17 SMP, up 134 days. MySQL 3.23.32 up 39 days, Queries/second avg: 753. It's a dual 933 PIII w/2gb ram. No table corruption. We don't even use precompiled binaries ;) Obviously one person's good experience doesn't mean there's not a problem somewhere, but we sure haven't had any trouble, and it's not for lack of hammering on it. -- Pete Harlan [EMAIL PROTECTED] - 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: connection lost on long-distance connection
Hi, Here is the way I would fix that problem (assuming you're a programmer) write a simple function check_connection(MYSQL **conn) for example. that will issue a query "SELECT NOW()" to mysql, if that query fails that means connection to mySQL has gone away and the function has to reconnects to mySQL, if not then life is good and the function exits without having to do anything else. Now after writing that function, call it right before executing any query in your program.

hunting down duplicate entries
We recently moved our hardware inventory database off of access (yay!) over to mysql. During it's days as an access database it aquired a numbered of duplicate entries. In every case (or at least the ones I'm working on) the serial numbers will be the same but likely all other info will be slightly different. One of the records will be basically correct and current, the other faulty. I want to be able to find every case in the database where more than one record shares the same serial number (which is not at present a key feild, but will be once the dupes are removed) so we can look at the records and determine which ones are valid and which ones need to go.

RE: hunting down duplicate entries
Select serialNo, count(serialNo) serNoCount from table group by serialNo order by 2 desc This will give you a list of all the unique serial numbers in your table. The ones with serNoCount1 are your duplicates. Without the capability to do subselects (yes, we all know...it's coming in the mythical v4!) you'll have to process that list in something like Java or PHP.

Re: connection lost on long-distance connection
well, i use mysql_query as ported from libmysql.dll function mysql_query(_mysql:pmysql;const query: pchar):integer;stdcall;external 'libmysql.dll'; this function is supposed to return non-zero on failure and zero on succeed ( includes select/update/delete/insert/show etc.etc). This function behaves entirely normal. Until being idle for a while. The function then fails after first attempt to connect. But why? i haven't got any sql error. So i tested with the console client. Both win32 and linux clients behave the same. Unfortunately i can only test on a win32 server at "long" distance, but in fact i'd espect a linux server to behave the same (since i didn't notice any real difference before) Normally you'd expect them in the status "ERROR 2006: MySQL server has gone away No connection. Trying to reconnect..." However, i got: "ERROR 2013: Lost connection to MySQL server during query" Both client and server think the connection is active, but for one reason or another they fail. in the server's processlist you'll see the anomalial client for a while. The client just reconnects using a new socket resource. So, i can test if the function succeeds, i could test if had a reconnection error, but: why should i test if the function is supposed to reconnect by itself... and then fails ??? imho the result should be false because: - the server is really unavailable or: - the query is invalid. however it's not only libmysql.dll that suffers from this problem, it's also the (original) client... regards, rene - Original Message - From: "Boulat Khakimov" [EMAIL PROTECTED] To: "Ren Tegel" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Thursday, March 15, 2001 1:11 AM Subject: Re: connection lost on long-distance connection Hi, Here is the way I would fix that problem (assuming you're a programmer) write a simple function check_connection(MYSQL **conn) for example. that will issue a query "SELECT NOW()" to mysql, if that query fails that means connection to mySQL has gone away and the function has to reconnects to mySQL, if not then life is good and the function exits without having to do anything else.

Re: MySql connection failed in browser
I've been running Redhat 7.0 for 5 months now on my production server, haven't had any trouble with it. I had trouble with the rpms for 3.23.34 that were on mysql.com's download page. The server was getting intermittent signal 11's with blown stacks. I assume a shared library mismatch. My guess is that it was due to some incompatibility with RH 7.0 as I hear the rpms on mysql.com are built against RH 6.2. I reverted back to 3.23.32 from redhat.com's updates ftp area for 7.0 and it worked fine. To be honest, I don't really know what was causing the signal 11's. They were intermittent and thus hard to track down. Is anyone out there running the 3.23.34 rpms from mysql.com on RH 7.0 successfully (under load)? ...without getting signal 11's? If so, then I'm wrong and it was something else. -bill At 08:06 AM 3/15/2001 +0800, Rolf Hopkins wrote: Since you say you're new to this stuff, let's start with the very basics.

Example DAO (not ADO)
Please example DAO!! ADO When you are coding with the ADO API and MyODBC you need to put attention in some default properties that aren't supported by the MySQL server. For example, using the CursorLocation Property as adUseServer will return for the RecordCount Property a result of -1. To have the right value, you need to set this property to adUseClient, like is showing in the VB code below: Dim myconn As New ADODB.Connection Dim myrs As New Recordset Dim mySQL As String Dim myrows As Long myconn.Open "DSN=MyODBCsample" mySQL = "SELECT * from user" myrs.Source = mySQL Set myrs.ActiveConnection = myconn myrs.CursorLocation = adUseClient myrs.Open myrows = myrs.RecordCount myrs.Close myconn.Close

RE: Very (excruciatingly) slow select
Hi Hannes Several approaches to achieve your work. One is upgrade your resource i.e. CPU, memory... I do not take this. Another is check all columns used inside WHERE clause whether they are indexed. If not, pls create indexes for them. it will definitely smooth better. Programmatically, I suggest you try to divide your query into several small queries. According to your query below, you are likely to join about 10 tables. As data grows, join those tables will produce undetermined large set of data.

RE: Very (excruciatingly) slow select
One more suggestion is, using LIKE to search (whatever your column is indexed or not) is definitely slow than using "=". I try it in 0.38 M records before. -Original Message- From: Tony Shiu [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 15, 2001 11:21 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject:RE: Very (excruciatingly) slow select Hi Hannes Several approaches to achieve your work. One is upgrade your resource i.e. CPU, memory... I do not take this. Another is check all columns used inside WHERE clause whether they are indexed. If not, pls create indexes for them. it will definitely smooth better. Programmatically, I suggest you try to divide your query into several small queries. According to your query below, you are likely to join about 10 tables. As data grows, join those tables will produce undetermined large set of data.

connecting Microsoft Access to MySQL
The "trick" is that while an autoincrement field is a nice thing to have as a primary key, is to put a timestamp field in each MySQL table (in addition to the primary key). - 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?

A common solution to a common problem, I suspect. If I understand correctly, replication creates a working copy of mysql on another server, but it looks like the algorithm to automatically change slave to master if the master dies will not be added until mysql 4.x (from 11.4 in the manual). Right. Is this still the case? Yes. Does anyone have any stories/suggestions/experiences in regards to rolling our own monitoring script? What about having a dual-master setup? It's a bit tricky to get right, but it certainly can work. Jeremy -- Jeremy D.

Well, try decreasing some of the values in your my.cnf file so that they more closely match the amount of memory you're willing to let MySQL use. Jeremy -- Jeremy D.

koi8_ru question
Hello list! The question should be simple. Does koi8_ru stands for koi8 RUssian or is it koi8 Russian/Ukrainian. The reason I am asking is that I remember the days when RU was used for letter. But it does not seem to support Ukrainian characters. I could use koi8_ukr but I do not know if it will sort Russian characters correctly. So far I changed koi8_ru.conf to support Ukrainian, Russian and Belorussian (all, but short U for Belorussian, because I do not know where it is in a sorting order) characters. But I afraid my provider will not patch MySQL just for me.
