RE: MYSQL DATABASE BACKUP
Yes and no If you are taking info from a live database you would have it in a steady state to copy it. This means locking the tables. But once you have a copy of the table all you would need to do is update the changes from the logs. Using replication for this I is the most simple way but would mean a second copy of MySQL but you would only need a low spec system.. I hope this helps...

Re: No support for multiple statements via JDBC?
Hi Allon, Only one query can be sent to server at a time. But your particular case can be handled with the single query Insert Into orders (Number) select Max(Number) FROM Orders; Anvar. At 04:45 PM 19/03/2002 -0800, you wrote: Hi All- We are using the mm driver for MySQL and multiple statements in one connection do not seem to be supported: I.e. SELECT @a:=MAX(Number) FROM Orders;insert into orders (Number) values (@a+1) The driver throws a syntax error. You can do either one of these statements on their own, and you can have a semicolon in the statement, but you cannot combine the statements. Are we missing something? How would you do a transaction or table lock without multi statement support? -Allon Allon Bendavid Imacination Software [EMAIL PROTECTED]http://www.imacination.com/ 805-650-8153 Visit Imacination and start selling on the Web today with Ch-Ching! - 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?

slow inserts and selects for fulltext indexes (mysql4)
Hi,
Is there a way to speed up inserts on a table with three fulltext
indexes? I'm using the multiple value insert format like:
insert into blah (field1, field2) values ('val1', 'val2'), ('val2',
'val3'), etc..
Perhaps this is a bug in the current mysql4 bk snapshot, but inserts and
selects on a table with three fulltext indexes are taking up to 23
seconds!
On average it's still taking up to 2.5 seconds to insert 50 records into
a table with 15000 records already (Which I think is kinda slow). But
every now and then it'll really slow down. I just logged 9 seconds for a
fulltext select on a table with 15000 records, and 23 seconds for an
insert of 106 rows on the same table. The machine has 400 megs of RAM
and is a PIII 750 with IDE drives. (as opposed to SCSI). Running MySQL
version 4 (the latest bk snapshot).
Here are the entries from the 'slow.log':
##
SET timestamp=1016613725;
select SQL_CACHE
id,search_category,search_jobtype,joblink,title,d_date_posted,n_date_posted,jobsite,jobsite_home,jobsite_con

# User@Host: root[root] @ localhost []
# Query_time: 9 Lock_time: 0 Rows_sent: 0 Rows_examined: 0
use workzoo;
SET timestamp=1016614900;
insert into search_cache (ctime,
search_category,search_jobtype,joblink,title,d_date_posted,n_date_posted,jobsite,jobsite_home
# Time: 020320 9:02:04
# User@Host: root[root] @ localhost []
# Query_time: 23 Lock_time: 0 Rows_sent: 106 Rows_examined: 13081
#
My my.cnf is included below. Based on the config above, particularly the
amount of RAM, is this the ideal config for my machine? (considering
that I do large inserts, updates and select on all three fulltext
indexes on the same table)
btw. I'm getting great performance on multiple sequential updates (over
200 records takes under .1 seconds) by locking the table.

I run a number of web servers all of which are mirrored by a second identical failover server. During normal office hours when the sites are busiest, the main server dumps all databases every hour to an NFS share and the failover server first drops all the backup databases and then imports them from the share. (The two servers have a private dedicated netwotk conection between them for this, separate from the main public Internet connections). The sites themselves, httpd configuration files, clinet FTP account info, etc are mirrored every night by simply updating all the files that have changed during the previous 24 hours. The failover server simply pings the main server every minute - if it fails to get a response for 2 minutes, then it stops Apache, Cold Fusion servers, etc, areconfigures its network interfaces to use the IP addresses of the failed server, replaces the Apache httpd.conf with the last one from the main server and restarts Apache. Outside of normal office hours and at weekends, the MySQL databases are synchronised every 3 hours and all changes made to the databases are logged using the NySQL logging feature. This can be 'played' back from the last update to reflect any changes made since the previous update. Simple but effective. Now that version 4.0.x is here, we might look at using the master/slave replication features this offers but there's no great rush and we need to do it in such a way that downtime on existing servers is minimised.

Re: Access denied on use mysql;
Joel, I have read the manual related to windows several times. But the problem that I was not having is not mentioned in the manual. I am not too sure if I am the one who needs root canal like someone earlier claimed. Or the manual needs one. I dont think the manual is helpful for beginners. Of course, I can say that the manual is not good. Of course, everyone can say it is free. The manual blends UNIX with Windows when they should be separate. And does not explain at all when mysql -u root -p does not work. It seems to work for everyone for the first time. Not me! Before getting into nitty and gritty details with you on my problem, please dont bring up hardware limits.

Perhaps for those who work in the museum. Your information on how to grant access to databases for specific users is very good, but I was not able to put it to work. I could not done it as a root user. It just wont grant access to me as a root user.I cannot type mysql -u root -p OR mysql -u root at all. It will display ACCESS denied. Same problems with first and second installation. The second installation was not necessary; you said you said waste of time. I am not going to disagree on that, either. But the NT server from the first installation must have still been running in the background without my knowing. I cannot explain how things went wrong with the first installation. But it seemed that the first installation transmitted disease to the second. Everything was impossible with both of these installations. Until then, I learned how to use WINMYSQLADMIN for adding my username and password. MYSQLADMIN did not do any good at that time. Still I was not granted access until that traffic light icon thing popped up in the right corner. There were 7 of them there. I never saw them before! But I think it was the turning point. After deleting one by one. To make story short...I learned how to stop and start server with that traffic light icon. When I stopped the server, I then started it with NET START MYSQL.. Then I was able to type in my user name and password (not root user this time), but think root user will be granted access. It appears that WINMYSQLADMIN is finally put to work. I was granted access on my user name/password. Everything appears to be working fine. I think removing those 7 traffic lites and STOP Server and then START server somehow fixed everthing for me. I have been granted access already without doing any configuration. I did not have that privilege in the beginning. The manual does not explain what I should do if mysql -u root -p does not work. And on how to use WINMYSQLADMIN on adding users. And also traffic lights. There is a program called MYSQLADMIN for DOS does not cover examples on how to using many different commands.

I think the documentation does not need 300 pages. And they should be separate with UNIX and WINDOWS. And explain what we should do if mysql -u root -p does not work in some pages.

Yes, GRANT is a MySQL command, and you do need to understand it. It would be easier if you had someone handy to configure a database for you. Then you wouldn't need to understand the GRANT command, just how to log in with a user name and password. Actually, your initial installation should be without a root password, so you should be okay.

Re: default value
From: Michal Dvoracek [EMAIL PROTECTED] s possible to create table with default value returned by built-in function ?? like: create table x (a int not null default UNIX_TIMESTAMP()); When inserting new column in table field a will contains timestamp? In general, this cannot be done. Default values cannot be the return of a MySQL function (as much as I'd love to use NOW() for default values!). However, there's one loophole. When inserting, not specifying a value for the first timestamp field in a table will generate the current timestamp. For example: -- CREATE TABLE foo ( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, email VARCHAR(50), entered TIMESTAMP ); INSERT INTO foo SET email='[EMAIL PROTECTED]'; SELECT * FROM foo; DROP TABLE foo; -- This will return: ++--++ | id | email| entered| ++--++ | 1 | [EMAIL PROTECTED] | 20020320092330 | ++--++ 1 row in set (0.00 sec) This won't give you UNIX_TIMESTAMP(), but it gives you the MMDDhhmmss timestamp.

RE: C API Question
multiple commands Not as far as I know, you need to open your file, read the commands and process them one at a time. The C API is not magic and has no more capability than you do setting down and typing in the commands yourself. What you can do is build one HUGE insert command from lots of individual row inserts, but you need to do that programatically, too. If you have loads of inserts to perform, it may be better to bulk load the data from a file made of the inserts' data than a record at a time if speed is an issue. I'd sure try the simple way first, though.

No. Not for the C API, or for any API. The client-server protocol requires that you issue a single query at at time. But there's nothing to stop you from writing a utility function that takes all the statements and issues them. Then you just call *that* function once.

Regarding your issue with accents, I understand more now about your problem, you are using shell tools in free BSD and you have not set the LANG shell environment variable.

unable to start mysql daemon - bug?
Hello, I hope someone here can help me out with this. I can't find anything in the documentation that does help. Everything points to the port being in use, however it isn't. I know it for a fact (netstat/telnet), no the mysqld also is not running, I know that for a fact (process list). I installed mysql-3.23.49-win on Windows 2000 to drive D: (the installer lets one choose the location). After reading the docs, I can see that I need to start the daemon like this: mysqld --basedir d:\mysql However, when I do it I get this: D:\mysql\binmysqld --basedir d:\mysql Can't start server: Bind on TCP/IP port: No error 020318 14:54:30 Do you already have another mysqld server running on port: 3306 ? 020318 14:54:31 Aborting 020318 14:54:31 mysqld: Shutdown Complete Netstat -a reveals that nothing is using port 3306. The port is free. There is no local firewall on the computer blocking the port either. I have also tried the --port option to point to another port. Nope. Interesting how mysql says all ports are in use, even when they are not. Running mysqld without any arguments results in a 30 sec delay, then the command prompt reapears and the deamon is not running. I added a my.cnf to the C:\ and this also has no effect. I then removed this and tried the winmysqladmin.exe and this also does not help. However, it also does not report any errors, with the exception of trying to generate an error report with it, which returns the wonderfull error message that it can't generate a report because it can't connect to the server, hmm, why offer to generate an error report if it can only do it when it can connect?

Re: Access denied on use mysql;
Hi Liyju, Before answering your note, I need to explain about the using the syntax for mysql -u user -p. If I use the format above for mysql -u root -p, I can press ENTER after typing mysql -u root -p and wait for the password inquiry. I dont need to enter the password (I dont have one, anyway) and then click ENTER again to bypass the password inquiry. I think it is the right way to do this if I am a root user. I am not sure if the root user can have a password. Does it? It does not sound possible. Perhaps someone has already mentioned it. I had learned the hard way to skip that inquiry. I doubt it is mentioned in the manual. Nevertheless, I have other problems with the installation, anyway. I think typing in mysql is the very same with mysql -u root -p. The grants are the very same. I hope it does. Does it? Your explanation about using the grant commmand for those who dont have password. mysqlgrant all on mysql.* to root@localhost identified by ''; Your correct! But I was not able to do that earlier because of something that went wrong with the installation. And I had 7 traffic lights in right corner without my knowing. After eliminating them and NET CLOSE MYSQL and then NET START MYSQL. I had done that alone several times before to no avail. It seems the combination of elimination of 7 traffic lights and NET CLOSE MYSQL gave me a good fix. I still dont know what the real problem was. I thought all I could do was install. By now, I know how to use mysql -u root -p, but I could not see how it could affect the installation in any way. I will be watching Mysql for several days. It looks like the second installation gave more problems. The NT server must have still running from the first installation. I thought I had deleted all my Mysql directores and subdirectories and also the NT server; but it may had never deleted the NT server that was still running. I do really appreciate many people who tried to help me out. - Original Message - From: Liyju Janardhan [EMAIL PROTECTED] To: alan4100 [EMAIL PROTECTED] Sent: Wednesday, March 20, 2002 12:30 AM Subject: Re: Access denied on use mysql; Hi Alan, I am using mysql on linux, so I suggest you to send cc to the list, let others help you.

fast,efficient query for counting
I'm setting up some tracking stats for (opt-in) e-mail campaigns, and
one of the things I'm tracking is click-thrus. I'm going to re-direct
traffic thru a script that will just count the number of clicks, and
store that number in a mysql table.
It needs to be fast and efficient, and I'm somewhat of a mysql newbie,
so I was wonderinf if there is any more efficient way to simply add a
number to the existing number in that table with mysql and perl. My way
seems like a lot of code to do a little task. Any help is appreciated!
# set up the db connection and SQL
$dbh =
DBI-connect(DBI:mysql:database=$database;host=$host,$user,$mysqlpassword,{'RaiseError'=1});
$select_number = select total_clicked from $table;
# actually execute the checking query
$sth = $dbh-prepare($select_number);
if (!$sth) { die Error: . $dbh-errstr . \n; }
if (!$sth-execute) { die Error: . $sth-errstr . \n; }
# loop thru the query and set the result variables
while (my $ref = $sth-fetchrow_arrayref) {
$total_clicked = $$ref[0];
}
# add 1 to total_clicked
$total_clicked=$total_clicked+1;
# update the number
$update_number = UPDATE $table set total_clicked = $total_clicked;
# actually execute the update query
$sth = $dbh-prepare($update_number);

Anis, My problem has been solved without configurating my.cnf. It looks like I dont need it at all because WINADMINSQL has created its own my.ini file. You may find my email to others about the fix.

Cheers Anis alan4100 [EMAIL PROTECTED] 03/20/02 08:00PM Joel, I have read the manual related to windows several times. But the problem that I was not having is not mentioned in the manual. I am not too sure if I am the one who needs root canal like someone earlier claimed. Or the manual needs one. I dont think the manual is helpful for beginners. Of course, I can say that the manual is not good. Of course, everyone can say it is free. The manual blends UNIX with Windows when they should be separate. And does not explain at all when mysql -u root -p does not work. It seems to work for everyone for the first time. Not me! Before getting into nitty and gritty details with you on my problem, please dont bring up hardware limits. I have an excellent computer DELL 4100 Dimension with well over 256 megs ram..etc..etc.. on windows xp just installed few days ago. My processor is near 1 giga hertz! Who has 64 megs and 100 HRZ? Perhaps for those who work in the museum. Your information on how to grant access to databases for specific users is very good, but I was not able to put it to work. I could not done it as a root user. It just wont grant access to me as a root user.I cannot type mysql -u root -p OR mysql -u root at all. It will display ACCESS denied. Same problems with first and second installation. The second installation was not necessary; you said you said waste of time. I am not going to disagree on that, either. But the NT server from the first installation must have still been running in the background without my knowing. I cannot explain how things went wrong with the first installation. But it seemed that the first installation transmitted disease to the second. Everything was impossible with both of these installations. Until then, I learned how to use WINMYSQLADMIN for adding my username and password. MYSQLADMIN did not do any good at that time. Still I was not granted access until that traffic light icon thing popped up in the right corner. There were 7 of them there. I never saw them before! But I think it was the turning point. After deleting one by one. To make story short...I learned how to stop and start server with that traffic light icon. When I stopped the server, I then started it with NET START MYSQL.. Then I was able to type in my user name and password (not root user this time), but think root user will be granted access. It appears that WINMYSQLADMIN is finally put to work. I was granted access on my user name/password. Everything appears to be working fine. I think removing those 7 traffic lites and STOP Server and then START server somehow fixed everthing for me. I have been granted access already without doing any configuration. I did not have that privilege in the beginning. The manual does not explain what I should do if mysql -u root -p does not work. And on how to use WINMYSQLADMIN on adding users. And also traffic lights. There is a program called MYSQLADMIN for DOS does not cover examples on how to using many different commands. I am a very new mySQL newbie. I barely start. I feel very sorry for the new comers to mySQL. But hopefully, these new comers are able to locate newsgroups like this. I think the documentation does not need 300 pages. And they should be separate with UNIX and WINDOWS. And explain what we should do if mysql -u root -p does not work in some pages.

Re: Speed question.
At 01:17 AM 3/20/2002, you wrote: An Oracle DB programmer reviewed a query that I wrote and told me that putting constants at the beginning of the query would make it slower. I thought I'd go to the experts on MySQL and be told the truth one way of the other. Example query: SELECT TABLE1.COL, TABLE2.COL FROM TABLE1, TABLE2 WHERE TABLE1.COL='CONSTANT' AND TABLE1.COL=TABLE2.COL [ OR ] SELECT TABLE1.COL, TABLE2.COL FROM TABLE1, TABLE2 WHERE TABLE1.COL=TABLE2.COL AND TABLE1.COL='CONSTANT' I know that indexes are important and such, the above is just an example to give some visual. Thanks for any help you can offer. Rob. Rob, The only thing to watch out for is that the constant should be the same data type as the column. Fox example, don't compare a Char to an Integer (or vice-versa) otherwise MySQL will have to convert the column on a row by row basis thus eliminating the use of the index.. Also if you perform a function on a column name, then it also can't use the index. So if you need to use functions it is best that you move the function to the constant side of the comparison if possible. Brent _ Do You Yahoo!?

Kathy, Sounds like mine, but it is fixed. I still dont know what the fix was. May I ask you how you signed in as Kreyes? Did you add username and password yourself? Since you are denied access to mysql (default) database, it surely sounded like mine. Before I may give you some help, may I ask you again how you signed in as Kreyes. Did you use mysqladmin? How long have you been using MySQL? Did you install recently? It sounds you may need to NET CLOSE MYSQL at DOS PROMPT. And then NET START MYSQL again.

If I use the format above for mysql -u root -p, I can press ENTER after typing mysql -u root -p and wait for the password inquiry. I dont need to enter the password (I dont have one, anyway) and then click ENTER again to bypass the password inquiry. I think it is the right way to do this if I am a root user. I am not sure if the root user can have a password. Does it? It does not sound possible. Perhaps someone has already mentioned it. I had learned the hard way to skip that inquiry. I doubt it is mentioned in the manual. Nevertheless, I have other problems with the installation, anyway. I think typing in mysql is the very same with mysql -u root -p. The grants are the very same. I hope it does. Does it? Your explanation about using the grant commmand for those who dont have password. mysqlgrant all on mysql.* to root@localhost identified by ''; Your correct! But I was not able to do that earlier because of something that went wrong with the installation. And I had 7 traffic lights in right corner without my knowing. After eliminating them and NET CLOSE MYSQL and then NET START MYSQL. I had done that alone several times before to no avail. It seems the combination of elimination of 7 traffic lights and NET CLOSE MYSQL gave me a good fix. I still dont know what the real problem was. I thought all I could do was install. By now, I know how to use mysql -u root -p, but I could not see how it could affect the installation in any way. I will be watching Mysql for several days. It looks like the second installation gave more problems. The NT server must have still running from the first installation. I thought I had deleted all my Mysql directores and subdirectories and also the NT server; but it may had never deleted the NT server that was still running.

Index only sometimes used
Hi All Could someone explain to me why an index in a select I am doing is only sometimes used. The select I do is a complex one with multiple tables, and when it uses the index it takes 1.5 seconds, but when it dosnt it takes 1 min and 25-50 seconds. I have simplified it down and founed the place the problem issee explains bellow: mysql explain select * from mailstat where domain_id in(1,3,4,7,50,20,11); +--+---+---+--+-+--++--- -+ | table| type | possible_keys | key | key_len | ref | rows | Extra | +--+---+---+--+-+--++--- -+ | mailstat | range | ind4 | ind4 | 4 | NULL | 239862 | where used | +--+---+---+--+-+--++--- -+ 1 row in set (0.00 sec) *notice ind4 is used mysql explain select * from mailstat where domain_id in(1,2); +--+--+---+--+-+--+-+--- -+ | table| type | possible_keys | key | key_len | ref | rows| Extra | +--+--+---+--+-+--+-+--- -+ | mailstat | ALL | ind4 | NULL |NULL | NULL | 2955648 | where used | +--+--+---+--+-+--+-+--- -+ 1 row in set (0.00 sec) *notice ind4 is NOT used mysql explain select * from mailstat where domain_id in(1); +--+---+---+--+-+--++--- -+ | table| type | possible_keys | key | key_len | ref | rows | Extra | +--+---+---+--+-+--++--- -+ | mailstat | range | ind4 | ind4 | 4 | NULL | 174922 | where used | +--+---+---+--+-+--++--- -+ 1 row in set (0.00 sec) *notice ind4 is used mysql explain select * from mailstat where domain_id in(2); +--+--+---+--+-+--+-+--- -+ | table| type | possible_keys | key | key_len | ref | rows| Extra | +--+--+---+--+-+--+-+--- -+ | mailstat | ALL | ind4 | NULL |NULL | NULL | 2955666 | where used | +--+--+---+--+-+--+-+--- -+ 1 row in set (0.00 sec) *notice ind4 is NOT used Basicaly, when I use '2' in the in() statement (and one or two other values from hundreds that do work), the index is not used. Initialy I thought that maybe the index was corupted, so I built a copy of the table, and inserted a handfull of rows, but the I got the same results, except for my new table 1 and 3 didnt work, but 2 did!. Out of interest I tried other indexes and found results like: mysql explain select * from mailstat where id558693; +--+---+---+-+-+--++ + | table| type | possible_keys | key | key_len | ref | rows | Extra| +--+---+---+-+-+--++ + | mailstat | range | PRIMARY | PRIMARY | 4 | NULL | 511375 | where used | +--+---+---+-+-+--++ + 1 row in set (0.00 sec) *primary key is used mysql explain select * from mailstat where id558694; +--+--+---+--+-+--+-+--- -+ | table| type | possible_keys | key | key_len | ref | rows| Extra | +--+--+---+--+-+--+-+--- -+ | mailstat | ALL | PRIMARY | NULL |NULL | NULL | 2956363 | where used | +--+--+---+--+-+--+-+--- -+ 1 row in set (0.00 sec) *primary key is NOT used If anyone could shed some light on this I would b most greatful :) Cheers, 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?

Updating MySQL using MS ACCESS
Hello, Does anybody know how MySQL works with MS Access especially when it comes to preventing concurrent updates from more than two users? I use InnoDB tables and link them through ODBC driver to MS Access for viewing and updates. Will there be any issues if two or more people have this type of ODBC link updating the same record? If yes, is there any way around it to prevent this from happening? How do I set the row locking from MS-Access or MySQL does this automatically? I'd appreciate any help on this.

RE: Fulltext Retrieval in big!??? Databases
Andreas, I gained some experience putting 15'000 documents into TEXT columns and indexing them. It's not quite 15gigs, but your amount of data will be reduced when you go from *.doc to pure ASCII. My table size is: -rw-rw1 mysqldaemon 187621564 Jan 8 20:02 plaintext.MYD -rw-rw1 mysqldaemon92874752 Jan 8 20:04 plaintext.MYI -rw-rw1 mysqldaemon8648 Jan 8 20:02 plaintext.frm Insert texts into the table and then later create the fulltext index with the ALTER TABLE statement. Having lots of RAM available speeds up index creation. It may be a lengthy process otherwise. And you have to increase some buffers. My model consists of the decisions from the Swiss Federal Court since 1954. Search runs are quite fast and I am happy with the results. BOOLEAN MODE still appears buggy but this situation may change shortly. Mail me off-list if you like. Thomas On Wed, 20 Mar 2002, Andreas Dau wrote: I have to plan a content retrieval system and am thinking of using mysql cause it's always been very reliable and convenient for my needs. Now, I do not have any experiences with databases of this size. The situation is as follows: We have round about 15gig of user documents (mainly MS Office documents such as doc or ppt). If you're storing those in native format, then they're not text documents and FULLTEXT searches are unlikely to benefit you. At least, I wouldn't guess so. Oh no, sorry I was not being clear. Of course I am thinking of a script that stores the _real_ text information into the field, which in addition will lower down the amount of data enormously since MS Office documents have a very poor snr *g* In that case, I'd say the best way to find out how well it'll work is to try it. Go for it! Well you're perfectly right that would be the best way. Unfortunately that is, as usual impossible since I have no comparable testing environment. Even If I'd take the effort and put all the documents into my local server , it's nowhere near to a high performance server and furthermore I do not have 50 people sitting here in my development LAN accessing all the different imaginable services. So I'd be really happy to get some _experience_ report. Is that understandable? My question is: can this be done with MySQL? What hardware (server) would be needed to get the results in a time anywhere near resonable? And, do the clients need to be tweaked or would it be acceptable to use a Browser for it (php on an Apache)? The client shouldn't matter all that much. The real work is being done on the server side -- unless you're planning to send several megabytes of search result to the client each time. :-) lol, naw *g* - 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?

But you said earlier about emails that did not do much of help. I was lucky. Perhaps you have to wait for your turn. First, I feel I am not ready to solve this problem for you because your telneting into the linux machine from Windows 2000 machine. I have never tried this. I can tell you what I know as a complete beginner. I need to correct my saying NET CLOSE SERVER. When it should be NET STOP SERVER. You need to use WINMYSQLADMIN for adding users. There may be other ways, but I only know this way. But in your case about telneting, I am not sure what your doing because I never tried it. I am not clear about telneting, are your accessing data remotely for editing,etc, from your local Mysql server. Or vice versa. your transmitting data from your local machine to the remote Mysql server. I think your just accessing remote data. Your reply may help. I can only describe about my present settings on my pc with mysql. The present settings right after the installation of Windows XP, I did not go anything beyond granting privileges to other users like you do. But it is ready to accept my typing input: USE MYSQL before the database changed in computer's reply. At that point, I assume I am granted access to this MYSQL database. Did you type in USE MYSQL command? I dont know why you cannot. I believe you should cc your emails to [EMAIL PROTECTED] Others will help you. I think you have mentioned emails, but got no help.

Re: ADO API support?
I have had very much success with passing sql commands via ado over the myodbc layer. I wouldn't trust addnew and update batch methods nor have I tested how or if they work, it's better to keep your connections to the database stateless for performance purposes. Meaning to execute dml statements use the ado connection object to establish the connection and pass your sql command to the db, then close your connection. Get in, get out. Don't hold anything open as your looping thru your rs... imho Same with retrieving recordsets, I recommend using disconnected recordsets which work terrific.

In some cases MySQL doesn't use indexes. If the result of query is more than 30% rows in a table, MySQL won't use indexes. It works much faster without index usage.

Re: Dual master/slave config
On Wed, Mar 20, 2002 at 04:48:11PM +0100, Danny Kruitbosch wrote: Hi, I'd like to setup two database servers in a dual master/slave config. So both machines will be each others master and slave. Only one server will be queried (selects, inserts/updates and deletes). In case of failure of one master a network switch will handle failover. The failed machine should then (manually) reboot and the database should start to catch up with be new master. Makes sense. - Are the any of you that have experience with this kind of setup? Yes. How did you do it? Simply configured both servers to slave off of each other. All the fun comes in making absolutely sure that updates can't go to the non-master when the real master is running. If you have auto_increment ids, that can be a real problem. How are you planning to do it at the switch to avoid race conditions? There is a hosting company which offers redundant MySQL service via a configuration like this (thanks to a hardware load-balancer). It works pretty well once we got it all working right. I've yet to find a hardware-based load balancer that will use the algorithm I'd REALLY like in this situation. I need to bug the guys at Foundry Networks about this. What I want is a load-balancer where you can say: (1) Send all connections to host A. It is master. (2) If host A is down, send all connections to host B. (3) Even if host A comes back up, keep sending connections to B. (4) Only when B dies should A become the master again. The key realization is that database connections (unlike most HTTP) are persistent, so if you're not careful you can end up with applications that have connections to BOTH servers and they believe they're connected to the master. Most load-balancers have a master/slave configuration, but it always gives preference to a particular host. IF that host comes back up, it becomes master again. That's where you can get bitten hard. This can probably be solved with LVS, but I really want a hardware solution. Jeremy -- Jeremy D.

MIN function returns different results with an index.
Hi, I'm trying to sort out an inconsistency where adding an index changes the results of a query. Seems like this is incorrect. I'm running 3.23.36-debug, under NT. I have yet to try this on other versions... The following may be a bug, but it's at least inconsistent. I wonder if this is fixed in a later version? I've found that when a query uses only the INDEX to get the answer to a query, the result of a MIN function may be different. Note that this seems to only happen when MYSQL takes the shortcut of looking only at the INDEX to get the answer. My guess is that the INDEX object contains a node for the record with NULL. And when querying, mysql doesn't bother to check whether the value it has looked up is real. I believe this is inconsistent with ANSI standards. Run the following scenario script to see the difference. Comments ? Thanks! Here's a scenario script. create table sometable ( col1 int,col2 int,col3 int,col4 int); insert into sometable values ( 1,2,3,null); insert into sometable values ( 1,2,3,4); insert into sometable values ( 1,2,1,5); explain SELECT min(col4), max(col4) from sometable; SELECT min(col4), max(col4) from sometable; create index sometable_col3_idx on sometable (col3); create index sometable_col4_idx on sometable (col4); explain SELECT min(col4), max(col4) from sometable; SELECT min(col4), max(col4) from sometable; - Results: mysql create table sometable ( col1 int,col2 int,col3 int,col4 int); Query OK, 0 rows affected (0.01 sec) mysql insert into sometable values ( 1,2,3,null); Query OK, 1 row affected (0.00 sec) mysql insert into sometable values ( 1,2,3,4); Query OK, 1 row affected (0.00 sec) mysql insert into sometable values ( 1,2,1,5); Query OK, 1 row affected (0.00 sec) mysql mysql explain SELECT min(col4), max(col4) from sometable; +---+--+---+--+-+--+--+---+ | table | type | possible_keys | key | key_len | ref | rows | Extra | +---+--+---+--+-+--+--+---+ | sometable | ALL | NULL | NULL |NULL | NULL |3 | | +---+--+---+--+-+--+--+---+ 1 row in set (0.00 sec) mysql SELECT min(col4), max(col4) from sometable; +---+---+ | min(col4) | max(col4) | +---+---+ | 4 | 5 | +---+---+ 1 row in set (0.00 sec) mysql mysql create index sometable_col3_idx on sometable (col3); Query OK, 3 rows affected (0.02 sec) Records: 3 Duplicates: 0 Warnings: 0 mysql create index sometable_col4_idx on sometable (col4); Query OK, 3 rows affected (0.02 sec) Records: 3 Duplicates: 0 Warnings: 0 mysql mysql explain SELECT min(col4), max(col4) from sometable; +--+ | Comment | +--+ | Select tables optimized away | +--+ 1 row in set (0.00 sec) mysql SELECT min(col4), max(col4) from sometable; +---+---+ | min(col4) | max(col4) | +---+---+ | NULL | 5 | +---+---+ 1 row in set (0.00 sec) -- Kevin Fries - 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: Inserting files from command prompt
I do this from the command line sometimes: mysql -h HOST -pPASSWORD DATABASE statements.sql The statements.sql file should contain full sql statements. This will read in the file and execute the sql 1 line at a time. The opposite would be to use mysqldump like so: mysqldump -h HOST -pPASSWORD DATABASE TABLE statements.sql This would dump the contents of the given table in the given database into the statements.sql file. This create full insert statements with schema.
