Locked out of mySQL.
Hello, I'm trying to learn mysql PHP. I recently set up the mysql server (with the file: mysql-3.23.32-pc-linux-gnu-i686.tar.gz) My problem is this: I either forgot the password, or neglected to set up any user accounts. The documentation says to do this: ./bin/mysqladmin -u root -p password 'new-password' ./bin/mysqladmin -u root -h twistedlogic -p password 'new-password' which returns the following: Enter password: ./bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: 'root@localhost' (Using password: YES)' I also tried renaming the mysql directory (in /usr/local/) and re-installing it. no. maybe I did something wrong there, because that seems to me it should have worked, being a binary package... and the mysql table being held in mysql/data/mysql. anyway, if anyone knows how I can get back in tell me! :) thanks, AJ. - 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: Locked out of mySQL.
In the manual First off, have you tried the following ... 6.15 Causes of Access denied Errors If you encounter Access denied errors when you try to connect to the MySQL server, the list below indicates some courses of action you can take to correct the problem: After installing MySQL, did you run the mysql_install_db script to set up the initial grant table contents? If not, do so. See section 6.12 Setting Up the Initial MySQL Privileges. Test the initial privileges by executing this command: shell mysql -u root test The server should let you connect without error. You should also make sure you have a file `user.MYD' in the MySQL database directory. Ordinarily, this is `PATH/var/mysql/user.MYD', where PATH is the pathname to the MySQL installation root. After a fresh installation, you should connect to the server and set up your users and their access permissions: shell mysql -u root mysql The server should let you connect because the MySQL root user has no password initially. That is also a security risk, so setting the root password is something you should do while you're setting up your other MySQL users. If you try to connect as root and get this error: Access denied for user: '@unknown' to database mysql this means that you don't have an entry in the user table with a User column value of 'root' and that mysqld cannot resolve the hostname for your client. In this case, you must restart the server with the --skip-grant-tables option and edit your `/etc/hosts' or `\windows\hosts' file to add an entry for your host. If so, then do this ... 20.11 How to reset a forgotten password. If you have forgotten the root user password for MySQL, you can restore it with the following procedure. Take down the mysqld server by sending a kill (not kill -9) to the mysqld server. The pid is stored in a .pid file which is normally in the MySQL database directory: kill `cat /mysql-data-directory/hostname.pid` You must be either the Unix root user or the same user the server runs as to do this. Restart mysqld with the --skip-grant-tables option. Connect to the mysqld server with mysql -h hostname mysql and change the password with a GRANT command. See section 7.34 GRANT and REVOKE syntax. You can also do this with mysqladmin -h hostname -u user password 'new password' Load the privilege tables with: mysqladmin -h hostname flush-privileges or with the SQL command FLUSH PRIVILEGES. Note that after you started mysqld with --skip-grant-tables, any usage of GRANT commands will give you an Unknown command error until you have executed FLUSH PRIVILEGES. -Original Message- From: AJ Hawks [mailto:[EMAIL PROTECTED]] Sent: Saturday, 27 January 2001 19:01 To: mySQL Subject: Locked out of mySQL.

Thanks. In 3.23.32 the test case I submitted apparently works better,
but bad things still happen, like the following table corruption:
DROP TABLE IF EXISTS t1;
CREATE TABLE t1 (
id mediumint unsigned NOT NULL auto_increment,
tag char(6) NOT NULL default '',
value text NOT NULL default '',
PRIMARY KEY (id),
KEY kt(tag),
KEY kv(value(15)),
FULLTEXT KEY kvf(value)
) TYPE=MyISAM;
INSERT INTO t1 (tag,value) VALUES ('foobar','baz');
CHECK TABLE t1;
The error says: "Can't read indexpage from filepos: -1". Moreover,
myisachk isn't able to repair it! (neither -r nor -o).
Tested on both sparc64-linux (sun4u) and sparc-solaris2.6 (sun4m).

Thank you for reporting this.
This will be fixed in a next release.
But it was really not a big problem - the table was not really corrupted.
myisamchk thought it was because there was empty index and non-empty
table - something that should never happen with normal index.
The bug was fixed by making myisamchk to treat such a situation
as normal.

Sergei

FreeBSD 4.2-stable + MySQL 3.23.32 sig 11 problem
Hi! I am having this weird problem that MySQL just dies with signal 11 several time per day when loads get just a bit hight (the load is very low, about 1 q/s and on some export ops it gets a bit high two time per 24 hours). Any way, FreeBSD 4.2 is not RELASE but STABLE which is cvsupped pretty often (last time was on Jan 20th). So all those problem with thread which Ken Manzel mentions are gone as well as broken compiler. I do not use port for MySQL and build it from the tar ball source like: gmake gmake install (i use gmake for a historical reason, bsd make could not build it some time ago). I just looked at the ports and saw a couple of compiler options: -felide-constructors -fno-exceptions -fno-rtti And it is said that w/o then MySQL could crash under high loads. Well, I tried to make an experiment: sh CXXFLAGS='-felide-constructors -fno-exceptions -fno-rtti' ./configure --prefix=/usr/local/mysql --with-charset=win1251 --localstatedir=/usr/local/mysql/data --with-mit-threads=no --without-debug --without-perl --without-bench gmake gmake install Now I am going to see if the problem goes away.

Re: AW: Strange behavior of MySQL 3.23.xx with GROUP BY ...
I think that is the wrong answer ... Standard-SQL and ANSI-SQL require that a column that is displayed and has no grouping function applied to it MUST also appear in the GROUP BY-clause!!! Sir, every dialect of SQL has it's non-ANSI quirks. I've never heard of Standard-SQL, but ANSI-SQL is a standard established by a standards organization and used by vendors as a basis for their own dialects. There has never been a commercial dialect of SQL that fully matched its contemporary ANSI standard. They have all deviated from it in some way. In this case, MySQL extends the standard by allowing you to include an extra column in the SELECT clause. The result: fldNAME fldMONAT sum(fldSALARY) boris 1 10200 stephan 1 6000 itself makes no sense ... none earned as much money in January (1) ... ! You didn't group by month. You grouped by name. Since you didn't use an aggregate function on fldMONAT, MySQL returns the value found in that field in the first row in the group. Since you did use an aggregate function on fldSALARY, MySQL returns the aggregate value for that group. Postgres gives an error, Oracle gives an error, SQL-Server 7 gives an error even M$-Access 2000 gives an error why doesn't MySQL? There are parts of the Oracle SQL dialect that will raise errors in other RDBMSs, but not in Oracle. There are parts of Transact-SQL that will raise errors in other RDBMSs, but not in SQL Server. There are parts of the MySQL SQL dialect that will raise errors in other RDBMSs, but not in MySQL.

The documentation says to do this: ../bin/mysqladmin -u root -p password 'new-password' ../bin/mysqladmin -u root -h twistedlogic -p password 'new-password' which returns the following: Enter password: ../bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: 'root@localhost mailto:root@localhost' (Using password: YES)' I also tried renaming the mysql directory (in //usr/local//) and re-installing it. no. maybe I did something wrong there, because that seems to me it should have worked, being a binary package... and the mysql table being held in mysql/data/mysql. anyway, if anyone knows how I can get back in tell me! [:)] thanks, AJ.
how to delete records older than 14 days
Hello, I'm trying to figure out the correct syntax for requesting the database to remove all records older than 14 days. The mysql query that I am using (from within php4) is: //---update news so only last two weeks of news are available---// $sql2 = "delete from news where newsdate DATE_SUB(NOW(), INTERVAL 14 DAY)"; $result2 = mysql_db_query($dbname,$sql); But it doesn't seem to be working. Here is the the definition of the "news" table: mysql describe news; +--+--+--+-+-++ | Field| Type | Null | Key | Default | Extra | +--+--+--+-+-++ | id | int(3) | | PRI | 0 | auto_increment | | hub | char(3) | YES | | NULL || | newsdate | date | YES | | NULL || | headline | varchar(100) | YES | | NULL || | article | longtext | YES | | NULL || +--+--+--+-+-++ 5 rows in set (0.05 sec) Basically this is for a news page, and items get pushed down the "list" (what the viewer sees) and then eventually are supposed to be deleted. Any suggestions on how to do this more efficiently would be welcome as well. Please email me directly (hit reply to the message).

C api functions blocks the computer
I'm resending the e-mail again so it may be clearest...
First of all, before I forget it...
My MySQL is:
mysql Ver 9.38 Distrib 3.22.32, for pc-linux-gnu (i686)
I have a problem with mysql_fetch_row...
When I use it the system goes to 100% CPU usage and nothing else, I get
not rows...
The problem seems to be inside the mysql_fetch_row function but I don't
know
I have just upgraded mysql to 3.23 but in the server I'm working there
is an older
one so I have to work with it...
* THIS IS C LANGUAGE ***
int main (int argc,char **argv)
{
MYSQL *MySQLConnect=NULL;
MYSQL_RES *result;// Resultado de las operaciones
.
.
.
Row = mysql_fetch_row(result); Here is the problem
j=0;
while(Row!=NULL);
{
printf("\n\t%u %4s",j,Row);
Row=mysql_fetch_row(result); And Here
j++;
}
.
.
.
}
END C *
I know result contains a valid address before calling the function,
because I use it to show how many rows are available some lines before,
(42 rows) but the system blocks anyway until I press Ctrl-c
The program waits before j=0 and stops there;
Any points on this...?
Thank you
Answer to my e-mail too, thanks...

Slight correction, for some reason the query below does NOT work on my sample DB unless I quote the date values.

RE: Possible to load only index MYI file into RAM?
Thanks for the help Kent and the rest of the list, Would be grateful for some help interpreting some mysql system variables. Just to recap on what I am trying to achieve, I want to load as much of a very large key file (224704512 mykeyfile.MYI) into RAM to improve selects. I did a "show status;" and the mysql variables for the keys were as follows :- | Key_blocks_used | 7793 | | Key_read_requests| 107315735 | | Key_reads| 219450 | | Key_write_requests | 0 | | Key_writes | 0 | Variable key_buffer_size is set to 8388600. I understand that the key_buffer_size is in bytes so I have a 8MB key buffer size. So I can increase this and that should improve select speeds. That's great. My QUESTION is : what do the "Key_read_requests" and "Key_reads" figures tell me. Are they in bytes? I'm not quite sure how to use them and interpret them to determine if select speeds are improving? Thanks everyone. This is such a great list! Michael Thomas -Original Message- From: Kent Hoover [mailto:[EMAIL PROTECTED]] Sent: Friday, January 26, 2001 2:39 PM To: [EMAIL PROTECTED] Subject: Possible to load only index MYI file into RAM? You can tell MySQL to use (lots) more RAM to cache Index Keys by setting an explicit value for its key_buffer variable. You can use the SHOW STATUS query to determine the cache hit rate by comparing these two values: Key_reads versus Key_read_requests. Key_reads divided by Key_read_requests would give you the cache "miss rate".

Problem with replication in 3.23.32
Greetings- I have been experiencing an unusual issue with replication in 3.23.32. We are using a dual-master setup on two FreeBSD4.2-STABLE machines. I am able to initially set up the replication, and issue simple updates from one or the other machine, but in certain circumstances we receive errors like this, although I've not changed any settings: 010126 23:31:14 Slave thread: error connecting to master:Can't connect to MySQL server on '86' (65)(22), retry in 3306 sec mysql show slave status; +-+--+-+---+ --+-+---+-+ -+ | Master_Host | Master_User | Master_Port | Connect_retry | Log_File | Pos | Slave_Running | Replicate_do_db | Replicate_ignore_db | +-+--+-+---+ --+-+---+-+ -+ | 86 | 209.95.64.253 | 0 | 3306 | test1-bin.001 | 0 | Yes | | | +-+--+-+---+ --+-+---+-+ -+ 1 row in set (0.01 sec) This has happened under a number of circumstances, the most recent being after resynching the two database, successfully performing a couple of updates, and then issuing "reset master" and "reset slave" on both machines. I then shutdown one machine's MySQL server, and inserted 100,000 very simple rows into the other server. Upon restarting the first server, it begins to replicate, all the way to about 93,000 records, and then quits with a message like this: 010126 22:27:30 Error reading packet from server: Could not find first log (read_errno 0,server_errno=65535) At this point, show slave status looks normal, but all replication has ceased. However, the next time that the slave is restarted, I see an anomaly such as the show slave status above, and also this in the master.info file (which was previously normal): test2-bin.001 0 73 test2.circle.n replicator 0 3306 ! 3306 10 As well as the following in the error log (timestamp equivalent to MySQL server startup): 010126 22:39:56 Warning: setrlimit returned ok, but didn't change limits. Max open files is 1064 010126 22:39:56 Warning: Changed limits: max_connections: 250 table_cache: 402 010126 22:40:41 Slave thread: error connecting to master:Can't connect to MySQL server on '86' (65)(65), retry in 3306 sec I have verified that the binary logs do exist and are readable by the mysql user. I have tried clearing all logs, resetting both master and slave on both servers, resynching and then restarting, and am still encountering this issue. A similar error also occurs when both servers are running - the replication stops at a certain point and the slave table gets corrupted as above. my.cnf reads as follows on both machines (with the master-host and server-id different): [mysqld] port= 3306 socket = /tmp/mysql.sock skip-locking set-variable= key_buffer=16M set-variable= max_allowed_packet=1M set-variable= table_cache=64 set-variable= sort_buffer=512K set-variable= net_buffer_length=8K set-variable= myisam_sort_buffer_size=8M set-variable= max_connections=250 set-variable= connect_timeout=60 log-update master-host=test2.circle.net master-user=x master-password=x master-connect-retry=10 log-bin server-id=2 Does anyone have any suggestions or ideas about this? Any help would be most appreciated. I would be glad to provide any more information that might be necessary. Please cc me off the list with any responses.

RE: RAW Device support
That would be more like DB2 or Oracle which would be more than happy to setup their own table space on a raw drive. They build their own file system and tables on the drive. Its very efficient and why a lot of large databases reside on DB2 or Oracle.

RE: 3 million+ records problems.
Adding another 192megs of ram or so would really boost performance. When I increased the RAM on my PIII 450Mhz from 128 to 256Mb, performance almost doubled for most queries on a 72k record table.

MySQL connecting to MSSQL7
Hi, It may sound strange, but the fact is that I'm needing to share data between one M$SQL7 and the MySQL. It's one business envoirnment that is migrating from one to the other, and in the meantime (until the new system does have all the features developed) I may still need to query the data in different structure. Did anyone has any information about putting MySQL either as a master or as a slave in a automatic replication configuration with M$SQL7 server ? I'm not talking about simultaneous updates, but only updates at MySQL to be replicated at M$SQL7 server, obviously in different machines, one running RedHat and other running WinNT.

Re: how to delete records older than 14 days
Sir, your DELETE statement runs fine on my computer. The problem appears to be in your PHP code. Post the problem to a PHP group with all the relevant lines, not just the two shown below. Hello, I'm trying to figure out the correct syntax for requesting the database to remove all records older than 14 days. The mysql query that I am using (from within php4) is: //---update news so only last two weeks of news are available---// $sql2 = "delete from news where newsdate DATE_SUB(NOW(), INTERVAL 14 DAY)"; $result2 = mysql_db_query($dbname,$sql); But it doesn't seem to be working. Here is the the definition of the "news" table: mysql describe news; +--+--+--+-+-++ | Field| Type | Null | Key | Default | Extra | +--+--+--+-+-++ | id | int(3) | | PRI | 0 | auto_increment | | hub | char(3) | YES | | NULL || | newsdate | date | YES | | NULL || | headline | varchar(100) | YES | | NULL || | article | longtext | YES | | NULL || +--+--+--+-+-++ 5 rows in set (0.05 sec) Basically this is for a news page, and items get pushed down the "list" (what the viewer sees) and then eventually are supposed to be deleted. Any suggestions on how to do this more efficiently would be welcome as well. Please email me directly (hit reply to the message).

Not much. Since you're constantly accessing the same small amount of files over and over, there just isn't enough metadata being changed for any of those three options to make any difference (all three options affect metadata only; file data itself is written async by defaut).

Re: Bug ?? combining NOT and like in where clause
Tor-Erik,
If 'I' was a language syntax interpreter, i'd see
"where not field like pattern" as
where (not(field) like pattern
and
"where field not like pattern" as
where (field !like pattern)
notice that not(field) probably returns 'False' so your first query is:
where False like pattern
with, of course, a empty result set
Use brackets anyhow because
"where not (field like pattern)"
makes sense!

Tested on the following versions of mysql: 3.22.32, 3.23.31 on Linux
Description:
"where not field like pattern" gives empty set, while
"where field not like pattern" return what i expect
How-To-Repeat:
create table testtabell(test varchar(10));
insert into testtabell values('test.com')
insert into testtabell values('test.no')
insert into testtabell values('test2.com')
insert into testtabell values('test2.no')
select * from testtabell where not test like '%.no';
This returns an empty set
select * from testtabell where test not like '%.no';
This one returns:
+---+
| test |
+---+
| test.com |
| test2.com |
+---+
2 rows in set (0.00 sec)
That is right.
I don't know if the first one is legal syntax, but it should
then return an parse error on the sql, not an empty set.

Re: how to get the union of the values in a SET column ?
Hi again Bob,
I know it's not 'proper' database design and I should have
normalized the one-to-many relationships to multiple tables.
However, it was fast and gave me a result which worked quickly
(and up against a mad deadline).
I think you've just identified the most common use of the SET datatype.
In your original posting, you said that a procedural solution
wouldn't scale well. If you database will never be more than 5,000
records, why are you concerned about scalability? Are you planning on
processing a hundred concurrent queries?
I meant scalability in terms of the number of items in the SET
(not the number of rows in the table). For example, consider a
SET field with 26 items -
eg. set_col SET ('A','B','C'. 'Z')
If I wish to find out which values of the SET have been used
at least once, I have to either:
a) Query for each member of the SET and find out which gives a result:
SELECT * FROM my_table WHERE set_col LIKE ('%A%')
SELECT * FROM my_table WHERE set_col LIKE ('%B%')
etc.
b) Select DISTINCT(set_col) and then parse the results
for for each member of the set .. which is a worse method.
I was hoping that since each member of the SET really
represents a number, that there would be some bitwise
operation that would painlessly produce all the members
of the SET that appear at least once.
If not, no worries - I'll redo the database properly
when I get some time.
Thanks again,
chas

Sir, the basic problem is that you've violated first normal form,
which states columns should only contain atomic (indivisible) data.
Since you plan to divide up the data in your columns, it's obviously
not indivisible.
My recommendation is to brush up on the first three normal forms and
redesign your tables. There may be a way to do what you want with
MySQL functions, but that will require a lot of processing and slow
your queries down. You'll be back where you started, with a solution
that doesn't scale well.
Chas wrote:
I have a column that is defined as a SET. For simplicity's sake,
let's say the column is defined as:
set_col SET ('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'Z')
After entering a few hundred rows, I know that some but not all
values of the SET have been used at least once. How can one work
out which values have been used at least once ?
Doing a SELECT DISTINCT(set_col) on the table might provide
something like this:
A,B,D
A,C,G,N,M,P
C,E,F,H,I,R,S
C,E,G,I
D,F
G,H,L,M,O
etc
But it then requires processing to work out which
values have been used at least once. It's not very
scalable.
Is there a method to retrieve a list of all the values
that have been used at least once ?

threads stuck waiting for table in 3.23.32 linux
DescripWell, for some reason after a table is being automatically repaired by mysql , some thread will be a suspended state. Mysqladmin will report a "waiting for table" in the state column of those threads. A look at the .err file showed me a "Warning: Checking table:" message. I waited a while and eventually I got my usual "Aborted connection" but the threads were still there. The oldest one had a times value of 95510. precise description of the problem (multiple lines) How-To-Repeat: run your server with myisam-recover and wait. Fix: mysqladmin flush-tables got rid of the offending threads Submitter-Id: submitter ID Originator:[EMAIL PROTECTED] Organization: MySQL support: none Synopsis: stuck threads Severity: non-critical Priority: medium Category: mysql Class: sw-bug Release:mysql-3.23.32 (Source distribution) Server: /usr/local/bin/mysqladmin Ver 8.14 Distrib 3.23.32, for pc-linux-gnu on i686 Copyright (C) 2000 MySQL AB MySQL Finland AB TCX DataKonsult AB This software comes with ABSOLUTELY NO WARRANTY.

RE: OK, I'll bite
NuSphere announced Gemini a few months ago and there is a press release on our website if you want to see the official details at: http://www.nusphere.com/releases/103000.htm Gemini is a project that NuSphere is doing to add a new table type to MySQL that will provide ACID transactions, row-level locking, and automatic crash recovery. The underlying code was part of the kernel of a successful commercial database and has the reputation for being one of the most reliable and easy to use databases available. Gemini brings mature enterprise-class database technology to MySQL in areas that have not been the focus of the popular MyISAM table type. Gemini and MyISAM table types are extremely complementary and I believe the combination will result in an expanding number of applications that will use MySQL as part of their core IT infrastucture not only for front end web functions, but also backend ecommerce functions. In November we met with members of the core MySQL development team in our offices to finalize design issues for the integration effort and since then have been hard at work building the gemini table handler. If you are interested watch this space or our website at www.nusphere.com for more information.

Re: ArabiaSoft and NuSphere
NuSphere is cheaper, comes with a printed MySQL manual, and IMHO, installs easier. - Original Message - From: "Frank J.

indexed text fields aren't handled correctly
Description:
When creating an index with multiple text fields, `where' clause
isn't handled correctly. If no index is present, "a = 'foo' and
b = 'bar'" does work well. However, if an index is present,
"a = 'foo'" and "a = 'foo' and b != 'bar'" work correctly, but
"a = 'foo' and b = 'bar'" doesn't. Surprisingly enough, "a = 'foo'
and (b = 'bar') = 1" still works!
How-To-Repeat:
create table test (a text, b text);
insert test values ('foo', 'bar');
insert test values ('foo', 'foo');
/* This works. */
select * from test where a = 'foo' and b = 'bar';
create index test_index on test (a(3), b(3));
/* This doesn't work. */
select * from test where a = 'foo' and b = 'bar';
/* But this works. */
select * from test where a = 'foo' and (b = 'bar') = 1;
Fix:
Use STRCMP.
