Re: *****SPAM***** when I installed mysql 3.23.43
Dave [ mysql query] when I installed mysql 3.23.43 it instructed me to be sure to add a password with the following results- : seaport2:/# /usr/mysql/bin/mysqladmin -u root -p password 'new-password' Enter password: /usr/mysql/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: 'root@localhost' (Using password: YES)' Read the man pages for mysqladmin for full details on all options (there are lots of them ;-P). The option -p is the password you use to connect to the server, however on a default installation you should specify no password. Essentially what you're doing is saying: Connect me to the server at 'localhost' with the password 'password' and user 'root' ...which is NOT what you want to do because the default databases don't expect a password _at all_ [which is why it is strongly suggested you change the passsword] Drop the -p so it looks like: /usr/mysql/bin/mysqladmin -uroot password 'newpassword' Also, don't forget to flush the privileges after changing the password.

Re: InnoDB on FreeBSD-Alpha problem
Heikki, I get the mysqld compiling/running ok. DB dump is restored ok locally. Locally everything wirks. But it what do you mean with this? If you issue SQL statements from the same computer, they work ok? Exactly. If I connect via local UNIX socket all happily works. If I just connect via network it crashes right away. If this only happens in an incoming network connection, then probably your network library is buggy. In Compaq Alpha C and C++ variables have to be aligned to machine addresses divisible by 4 or 8, which is not required in Intel x86. Looks like some variable in the library is not aligned. It's no such thing as network library in FreeBSD. It's networking support in kernel. And it's perfectly ok. Whole bunch of other apps work w/out any problems. MySQL server app is crashing. It only started when I enabled InnoDB at compile time. Before it was no such problem. So somewhere I guess they mangle with addresses and use unaligned one. It happens on *network* level. So even telnet connection on 3306 crashes it. Not even in logon phase. Or early in logon phase. So it's a bug in MySQL somewhere. I will try to troubleshoot it down to the source code line.

Re: InnoDB on FreeBSD-Alpha problem
Heikki, if you can compile with the gcc -g option and run mysqld inside gdb, then you probably see in what function and line it crashes. That's what I am going to do. If you just take a connection to mysqld, it does not execute InnoDB code at all. Well I was connecting to it before ok, but it was w/out InnoDB and older version. Yesterday I upgraded it to new stable and added InnoDB all at once. So I am not really sure it the bug was introduced with the new stable version or InnoDB enabling. Sounds more reasonable that it's just in the new stable version vs. InnoDB since it's in connect time. .So the bug is probably in the network code of MySQL or the libraries involved, for example, glibc. I guess that libraries are always involved in network communication. The kernel API is more primitive. In FreeBSD it's no glibc. And system libs aren't involved in networking. Kernel exposes POSIX-networking interface directly. So bug is somewhere in MySQL code. Will find out and make the patch.

Re: Query slowing down, need advice
Thanks for your input. Especially Tod for breaking it down at the hard ware
level and making me realize what is possible.
I have re-evaluated how this is going to work. Instead of trying this with
one query, I am using 2. I forget somethimes that MySQL is better at
running simple queries really fast than complex single queries.
I am now using Full-Text indexing (people will just have to upgrade) to
retrieve any id of a row matching my search criteria eg.
select id from single_table where MATCH (body,author,subject) AGAINST
('search criteria')
I then read all those id in from the results. That takes .2 seconds on my
server. I then feed those results (current 4450 rows) into a second query.
select id from single_table where approved='Y' and id in ( big id list )
order by datestamp desc
That query takes .2 seconds. id is the primary key so look ups on it are
really fast. There is a key on approved, datestamp as well.
From that I have the rows I am looking for. All in .4 seconds. This is
with 1Mil+ rows. The speed is consistent for all search criteria.

Re: Urgent: lost connections,
Lo Victoria FreeBSD 4.6-STABLE (Master), MySQL 3.23.51 Windows 2000 Professional (Slave):, MySQL 3.23.49-nt I've recompiled the master about three times now, and it still crashed. Eventually, it came to such a extend that the moment I open port 3306 MySQL would crash. I can just use telnet ip 3306, or open a netcat on port 3306, and MySQL would die. So far, the only way I found to keep the FreeBSD Port up, was to recompile it with debug support. I so far have 90 minutes uptime on the Master with debug support compiled in, but it's needless to say not really the desired result. I also don't think it's got anything to do with the replication. In my attempts to debug this, I've disabled (shut down), the slave mysql server, and the master would still crash the moment I open a tcp socket... It also doesn't seem to be a generic system library or something as the error log states, because I have *nothing* else on my box that is giving me any problems... If it where to be a shared lib used by many applications, surely more than just MySQL would have been dying because of the faulty / corrupted library. -- me - Original Message - From: Victoria Reznichenko [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, August 17, 2002 5:13 PM Subject: Re: Urgent: lost connections, Chris, Saturday, August 17, 2002, 2:04:40 AM, you wrote: CK Lo everyone, CK I've implemented replication on my MySQL Server...

Strange PHP + MySQL add / update issue with NULL values
I have a table where I have specified several columns which I have specified that NULL values are not allowed. I have created a PHP based create / update / delete page where users can update the table. I have an INSERT script that takes the user input and generates the following query statement. Insert: INSERT INTO table SET required_field = NULL I have set the required field to NULL which results in an error because naturally this is a required field. If I use an actual value the query runs fine and the row is added. Now I have another page that allows the user to update the existing rows. Update: UPDATE table SET required_field = NULL WHERE id = '2' This assumes that the user has cleared a required field and is attempting to enter NULL data for a required field. If I execute this directly in mysql the query fails (0 rows touched). If I execute this via PHP from the web page the row is updated but it passes instead of NULL so the row is updated. The query above is echoed right from the web page and pasted into MySQL. Any idea?

Re: [PHP] RE: Strange PHP + MySQL add / update issue with NULLvalues
That is what PHP / MySQL seems to be doing to the query once it is sent. I want to pass NULL to the column not a blank field (i.e. for text and 0 for numbers). If I do INSERT INTO table SET required_field = I get the same results. NULL means no value at all and is a empty string which in MySQL terms are two completely different things. I have also noticed another weird issue: UPDATE table SET required_field = NULL, notrequired_field = NULL WHERE id = '2' Results in: idrequired_field notrequired_field 2 NULL This is strange... All of my NOT NULL columns result in '' data instead of NULL but colunms that do not have a NOT NULL constraint do result in NULL!

Words in fulltext search
Hi. I'd like to know is it safe to tune mysql-4.0.2/myisam/ft_parser.c #define true_word_char(X) (isalnum(X) || (X)=='_') to #define true_word_char(X) (isgraph(X) (X)!='@') Or is anywhere better place to redefine chars which are accepted by fulltext search ?

I want to add up in a select Statement
Hi If I do this and projectdonations is say 5 sqlst = update sfproducts set projectdonations = projectdonations + 1 WHERE prodID = ' sProdID ' projectdonations then = 6 - great however the number I want to add is in a variable called test value and if I do this and say testvalue is 66 sqlst = update sfproducts set projectdonations = projectdonations + testvalue WHERE prodID = ' sProdID ' projectdonations then = 566 so its appending rather than adding. Im sure its just a syntax thing but for the life of me I can work it out pointers appreciated.

Replication and tmp tables
Hello, I am continuing to have what seems to be intermittent problems with replication. I have attempted to exclude temporary tables from replication by using ignore wild specifications in my.cnf on both master and slave. For some unknown reason there are times that MySQL still tries to replicate a temporary table.

Lo everyone,
I seem to be having a problem with the structuring of my query - more
specifically, with the WHERE clause...
mysql SELECT ZoneName

CompanyDetails.CompanyID=CompanyDNSZones.CompanyID

How do I get it to only return the item specified in the WHERE clause?
I explictly tell MySQL in my where clause to only return results where
CompanyDNSZones.ZoneName='megalan.co.za', so where does it fall out
returning lists.megalan.co.za as well?

PS: Just for interest takes, can LEFT / RIGHT / a combination of LEFT
RIGHT joins be used to cross-reference three or more tables, or is it
limited to 2 tables only?
