processes stuck in Opening table state

Slow query
Hi all. I'm using MySQL server 3.23.47 (client 3.23.44) on Windows 98 (...sorry) accessing to database via ODBC (MySQL ODBC release 3.5.01.01) and VC++6.0 MFC (CRecordset). I have noticed that queries are really slow... with a simple SELECT like this: SELECT ID_Field, Text_Field, Date_Field, Num_Field FROM mytable ORDER BY Num_Field the server takes about 31 seconds to show all the 2872 records. I tried to modify some parameters in the DSN and I noticed that checking 'Use compressed protocol' the same query takes only about 6 seconds to complete and I said That's great : I have used for the tests WinSQL (www.indus-soft.com/winsql) and -of course- the program I'm developing. Now I would like to know: Am I doing something wrong? Is that a bug? Is that a normal server behaviour? Why is that?

Innodb replication and Database renaming question
Hi, I'm still using Mysql 3.23.46 because, as far as I remember, in .47 was reintroduced the limit of 500 chars max in Innodb primary keys (limit that would break my application). Is it still present ? Is it present in Mysql 4 ? I also need to know if Innodb is reliable in replication mode. I remember that with past versions, if the master broke the slave would lose synchrony, or something of this kind that would make a self-recovery impractical. I need to implement a read-only fall-back DB, and I'm planning to use a combination of cron script to dump the live db to the slave after having renamed the good (old) versions, and after having verified that all the data in the new dump is fine, renaming the new db to the right name. The problem is that I can't find in the manual a command to rename a database. I will appreciate any suggestion, Thanks, Nico - 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?

It'a a very strange situation. You can run install mysql_install_db
but you should first move old privileges tables from mysql data dir.
You can read about running mysql_install_db at:
http://www.mysql.com/doc/m/y/mysql_install_db.html
After running mysql_install_db you will get new privileges table with
user 'root' without a password and default anonymous user.
You can also start mysqld with '--skip-grant-tables' option and re-create missing
columns using ALTER TABLE statement to add those missing columns:
`Grant_priv` enum('N','Y') NOT NULL default 'N',
`References_priv` enum('N','Y') NOT NULL default 'N',
`Index_priv` enum('N','Y') NOT NULL default 'N',
`Alter_priv` enum('N','Y') NOT NULL default 'N'

Re: Changing Default for Not Null to NOTHING

MYSQL,Linux large threads number
Hello mysql,
Some time ago I wrote about slow down of mysql with large number of
threads, which is quite common in Linux-Apache-Mysql-PHP enviroment.
The test was simulating the worst case of concurrency - all the
threads are modified global variable in a loop 500 times in
total, using standard mutex for synchronization. The yeild is used
in a loop to force even more fair distribution of lock usage by
threads and increase context switches, therefore it did not change
much with large number of threads. I.e with 64 threads time without
yeild is 1:33.5
Test was run on PIII-500 1G RAM Kernel 2.4.18. 3 runs were made for
each number of threads and best results were taken:
Num threads. Time Peak cs rate.
2 53.4 179518
4 53.8 144828
16 1:06.3 85172
64 1:48.1 48394
256 8:10.6 10235
1000 36:46.2 2602
The surprising thing is the time grows in less then linear way for up
to 64 threads but later it stars to go linear way or even worse. May
be this is because some other process are sleeping in the system which
also is used in scheduling.
For Next test I'll try to use Ingo's scheduler to see if it helps to
solve the problem, also I'll try to test real mysql server to see
which slowdown it will have.
CODE: (Dumb one just for test)
#include stdio.h
#include pthread.h
#include time.h
#define NUM_TH 1000
#define TOTAL_VALUE 500
#define LOOP (TOTAL_VALUE/NUM_TH)
pthread_t th[NUM_TH];
int thread_data[NUM_TH];
int rc,rc2;
int global=0;
pthread_mutex_t mut = PTHREAD_MUTEX_INITIALIZER;
pthread_mutex_t start = PTHREAD_MUTEX_INITIALIZER;
void f(int *thn)
{
int i;
pthread_mutex_lock(start);
pthread_mutex_unlock(start);
for (i=0;iLOOP;i++)
{
pthread_mutex_lock(mut);
global++;
pthread_yield();
pthread_mutex_unlock(mut);
}
}
main()
{
int i;
pthread_mutex_lock(start);
for (i=0;iNUM_TH;i++)
{
thread_data[i]=i;
rc=pthread_create(th[i],NULL,f,thread_data[i]);
if (rc!=0)
{
printf(Failed to create thread #%d errorcode:%d\n,i,rc);
}
}
pthread_mutex_unlock(start);
for (i=0;iNUM_TH;i++)
{
rc2=pthread_join(th[i],NULL);

RE: Getting a text field in a table....
I don't believe you specify a size for a column of type TEXT. Only types CHAR and VARCHAR take a size. http://www.mysql.com/doc/B/L/BLOB.html says: A BLOB is a binary large object that can hold a variable amount of data. The four BLOB types TINYBLOB, BLOB, MEDIUMBLOB, and LONGBLOB differ only in the maximum length of the values they can hold. See section 6.2.6 Column Type Storage Requirements. The four TEXT types TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT correspond to the four BLOB types and have the same maximum lengths and storage requirements. Whereas, http://www.mysql.com/doc/C/H/CHAR.html says: The length of a CHAR column is fixed to the length that you declare when you create the table. The length can be any value between 1 and 255. and... Values in VARCHAR columns are variable-length strings. You can declare a VARCHAR column to be any length between 1 and 255, just as for CHAR columns.

mysql_num_rows/insert/3.23.41
Found a strange problem with a system here I'm wondering if anyone can help with. Got a v3.23.41 installation (source build) on RedHat 6.2 using BDB tables. A front end program uses this database via the C API. gcc on this system is egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) At one point the front end generates an INSERT query to put a new record into the main table of the database. In another bit of the code it does a check to see if a particular record exists (SELECT query on the primary key followed by a mysql_num_rows on the result) before trying to update the record. Now this program has been running fine for a good while, but yesterday in the space of five minutes I got 6 warnings from my front end program that the users were trying to update records that didn't exist. When I did some digging, it looks like the records were/should-have-been present. So I've got two possibilities: 1. The initial insert for the six records didn't work. I'm not sure about this, since there were other record inserts being done around the same time frame that did work. 2. For some reason, either my SELECT decided to return no results, or mysql_num_rows decided to return zero. I'm going to put in some error trapping on the insert now, so if it does fail at least I get an error message. I'm a bit loathe to do this since the system has been so stable, (100K's of transactions at these are the first failures, so replicating the problem is near enough impossible). Plan B is to replace the r41 install with a local build of r49a(/r50?) in case it's a know problem now solved. Any ideas oh great MySQL gurus?

I would really like the server to do the work though through the grant though I could create the table first, then make the grants, then delete the tables, BUT I have a slave replicating this database ( so when I load the data, it will be replicated right from the get go) and I would rather not have that unneccissary stuff in the bin logs.

My JDBC does not work.
I have spend three days try to get jdbc for mysql work, but failed. I am
very frustrated. I will
be appreciated if somebody can help me out.
I have redhat 7.2 OS, I download the sever and client mysql .rpm files and
instaled it, i believe succssfully. i use command like 'mysqladmin
version' to test the mysql server, the server seems work fine, I have a
mysql user account 'jianping' which has been granted all global privilges.
I downloaded the JDBC mm.mysql-2.0.4-bin.jar to my system and set the env
varible properly.
I have a database called 'evote' and there is one table 'stocks' in the
database.
I use the code download form a jDBc tutrial website the code is:
import java.sql.*;
import java.io.*;
import java.util.*;
class StocksMy {
public static void main (String args []) {
try {
Class.forName(org.gjt.mm.mysql.Driver).newInstance();
System.out.println();
// Create a Connection and a Statement
Connection conn = DriverManager.getConnection(
jdbc:mysql://localhost/evote?user=jianpingpassword=ping1830);
System.out.println(33);
Statement stmt = conn.createStatement();
// Select all columns from the STOCKS table
ResultSet rset = stmt.executeQuery (select * from stocks);
// Iterate through the result and print the records
while (rset.next()) {
String ticker=rset.getString(1).trim();
String title=rset.getString(2).trim();
String price=rset.getString(3).trim();
String blanks=
;
// print the data in a table format
System.out.print (ticker);
System.out.print(blanks.substring(1,8-ticker.length()));
System.out.print (title);
System.out.print(blanks.substring(1,41-title.length()));
System.out.println (price);
}
} catch (Exception e) {
System.out.println(StocksMy: JDBC exception);
System.exit(1);
}
}
}
I added some System.out.println () trying to the code.
The code can be compiled succesfully, but when i tried to execute it, it
gave folliing output.
1
Stocksmy: JDBC exception
because it did not print 333 so I believe the problem is that
the connection can not be establish.
Thanks in advance.

Re: A problem with ROUND()
Your problem, I _think_, is that your query works as follows:
for i = 0 to table_name.rows {
row -- table_name.row[i]
if row.count = ROUND(rand() * 10) then result += row
}
NOTE: ROUND(rand() * 10) is performed FOR EACH ROW in your table. You
actually mean for it to be performed once and that specific row be returned.
The solution, then, is to have a constant in your WHERE clause. Or at least,
determine its value outside of the select statement.

Replication: bin-log confusion and other
Hi, i'm setting up a rather simple replication setup but i'm not able to understand the behaviour of mysql (3.23.44) - one server is master, all update are on master - some of the databases on master should be replicated to some slaves; the others should not - create/drop database/table should be replicated for theses databases - cross updates should work - If bin-log-do-db=xxx is set on master and nothing on slaves, then - as stated somewhere in the archive - crossupdates doesn't work. In addition, create database is not recoginzed and drop database is only recognized if it is useed ( seems to be the same Problem ) - If nothing beside bin-log is set on master, with replicate-do-db= or replicate-ignore-db= on slaves problem seems to be the same (as stated in the mysql-doc ). Furthermore I don't want to use any of the ignore directives Can i ignore %.% and replicate-do-wild=db.% ? - if replicate-do-wild-table=dbname.%, then i get the create database for any database from master. Isn't it possible to do something like bin-log-do-db=xxx on master, nothing on slave and to get all updates to mysql concerning this database (i.e. drop database, create database, any crossupdates) as one - o.k., me - would think prior to use ? Another, similar, effect: i would assume SET sql_log_bin = 0 to forbidd logging for *all* processes and all databases, but it seems to be only for the current process and all databases. Is there a command like set sql_log_bin_ALL|ME_DATABASE|ALL = 0 ? For now, i have to shtdown mysql, change my.cnf, then restart. Third Problem: What about sort of SET other_clients_can't_connect = 1 ? For sure, i can do flush tables with read lock, update and release lock, but possible client's would not notice, so i have to shutdown the db after my update to get sane state.

RE: replication through port forwarded firewall
From what you are writing here it looks as though you are porting a database to the slave that has already been bin logging. If your master has been logging the database in question, and you are copying that database over to the slave, then of course when it reads the bin logs from the master the data is already in there. When you port the database into the slave it should be a copy of the master database just at the instance you started the bin logging. My Slave-Master Setup ( at this time if you want to start over, stop the slave and the master) 1. Dump master database ( perhaps you should lock all the tables from writing at this time ) Or stop the master server and tar/gzip the master database directory and send it to the slave server to use later 2. Set master settings( if possible at this time, remove the bin logs and index file from master HOSTNAME-bin.### and HOSTNAME-bin.index) 3. Create database on slave and load it with the master dump ( remove the master.info if starting over ) 4. Set slave settings 5. Restart the master server so it starts the fresh bin logging ( unlock your tables if you locked them before ) 6. Restart the slave server so it starts its replication process You could combine a couple of the steps 1-3 by using this on the slave db mysqladmin -p create databasename mysqldump -p -h0.0.0.0 -c -q themasterdb | mysql -p databasename ^^^ host ip address this will dump right into the database on the slave ( again you might want to lock the master from writing at this time ) don't know, this might be your problem OR you could lock the master from writing, note the position and bin file it is on, copy the master as is, send it to the slave and use the MASTER CHANGE command to set up the binlog and position on the slave, then start up the slave and unlock the master of course hmm what else GRANT FILE on *.* to replicant@'slaveIP' identified by 'passwd'; This must be FILE and the *.* must be *.* not database.* ( FILE is a global grant option and is not available to database, table, column permissions) -Original Message- From: John Hunter [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 11:23 AM To: [EMAIL PROTECTED] Cc: MySQL mailing list Subject: Re: replication through port forwarded firewall Van == Van [EMAIL PROTECTED] writes: Van This means you need to re-initialize the slave; i.e. stop the Van master and slave; copy the data dir to the slave; start the Van slave (ensure the perms on the slave are correct first); Van start the master.

Re: A problem with ROUND()
I think you misunderstood how this is going to work. The expression ROUND(rand()*100) is not a constant, so it is going to re-evaluate it and generate a *different* random number for each line in the table. Apart from anything else, this is going to be slow because it will have to scan the whole table. There is an INDEPENDENT probability of one in a million that it will match each separate line, so you will get an average of one hit but, as you have found, sometimes none or two. One way to solve this would be to use a user variable: SET @Random = ROUND(rand()*100) ; SELECT count, character FROM table_name WHERE count = @Random ; Alternatively, this might work: SELECT count, character FROM tableName ORDER BY rand() LIMIT 1 ; Alec Cawley --- I have database with table and 1 milions random characters.

Re: Grants to a database table that doesn't exist yet
Luc, I think you have to do the manual inserts to make this work before the tables are there. I wrestled with this problem briefly, before writing a quick script.

Extending tablespace for innodb
Hello, How can I increase the size of the tablespace for innodb tables? Can you say if this is a correct procedure: 1. Dumping the database; 2. Stopping it; 3. Deleting innodb log files (ib_logfile0, ...) and innodb data file specified in innodb_data_file_path; 4. Changing size of data file in innodb_data_file_path; 5. Starting mysql; 6. Restoring the databases from the dump file. Does it seems to be a correct procedure, or I've messed up something?

Re: How MySQL handles variables
Hi GEORGE, The typical way refers to the update syntax. Ideally, I would like to be able to do something like that: - read the value of the variable through a read statement. -Specify the value to be appended. -Do the task. Could you please help me out with that? I would like to ask a simple question about the way MySQL handles string variabels. Say i have a variable whose value is foo and I want to change it to foobar. Instead of doing it the 'typical' way, I would like to ask whether there is any mysql command that will allow me to say read the value of the variable and then append bar to it. What is the typical way that you don't want to use? Check out CONCAT( foo, bar ) = man ref 6.3.2 String Functions Sounds straightforward enough: - SELECT colNm [etc] FROM ... WHERE ... - ascertain the bar to be appended - UPDATE tblNm SET colNm = CONCAT( colNm, bar ) WHERE ... The ticklish part is making sure you get the WHERE clause(s) correct. I'm not sure what you wanted me to say about the middle task. That would depend upon where you were getting the data to be appended from, and if you are using native-MySQL or some language calling MySQL across an API/whatever.

mingw, mysql c api, win2k cmd line error
I am having a heck of a time getting a simple c program up and running using mingw and
the mysql c api.
My makefile is simple enough I'm not sure what the -lm switch on the search compile
line is for but I saw it in someone's makefile on the web so I through it in hoping it
would work):
# makefile for search
CC = gcc
CFLAGS = -Ic:\progra~1\mysql\include
COUT = search.exe
OBJ = main.o search.o site.o sqldb.o
default : search
pause
copy $(COUT) c:\usr\www\localhost\htdocs\cgi-bin\$(COUT)
search : $(OBJ)
$(CC) $(CFLAGS) -o $(COUT) $(OBJ) -Lc:\progra~1\mysql\lib\opt -lmysqlclient -lm
main.o : main.c
$(CC) $(CFLAGS) -c main.c
search.o : search.c
$(CC) $(CFLAGS) -c search.c
site.o : site.c
$(CC) $(CFLAGS) -c site.c
sqldb.o : sqldb.c
$(CC) $(CFLAGS) -c sqldb.c
clean :
del *.o
del $(COUT)
--
My c program contains the following (neither function is being called):
#ifndef SQLDB_H
#define SQLDB_H
#include windows.h
#include mysql.h
typedef MYSQL SQLDB;
SQLDB *sqldb_init(SQLDB *);
int sqldb_term(SQLDB *);
SQLDB *sqldb_init(SQLDB *sqldb)
{
return mysql_init(sqldb);
}
#endif /* SQLDB_H */
--
And the following error is being reported:
gcc -Ic:\progra~1\mysql\include -c main.c
gcc -Ic:\progra~1\mysql\include -c search.c
gcc -Ic:\progra~1\mysql\include -c site.c

Server Databases Clash
I read your article and found it to be interesting and overall, quite accurate. I do have one bone to pick with you however. I know the MySQL staffer who worked the MySQL portion of the test. I had occasion to meet him and talk briefly about the PC Magazine test in Houston the week following the test. From my discussions with him, I also believe that the MySQL folks asked if they could use a Linux based platform instead of Win2K and were told no. That's fine in that it makes the comparisons fair for all vendors. Frankly, I was surprised that MySQL did as well as it did under Win2K! My problem is that you then published numbers for MS SQL Server running in a non-standard configuration from the rest of the test! ... As an extra data point, we also rewrote the benchmark in ASP .Net and, due to time constraints, tested just SQL Server on this platform. We stress that the results of this test are not comparable to the Java benchmark results because the ASP .Net test used a different Web server (Internet Information Services 5.0), different application engine (ASP .Net) and different database driver (OLE DB). However, our results do provide evidence that this all-Microsoft software stack can produce excellent performance, peaking at just under 870 pages per second ... This leads one to believe that SQL Server and an all Microsoft solution is better than the 600 pages per second that MySQL and Oracle were able to serve up. At least that would have been the conclusion that I would have drawn from your article, not knowing the the test environment was supposedly fixed for all competitors. If you want to let SQL Server turn in it's highest numbers by running on a native platorm, that's fine. Just let the rest of the competitors do the same. Yes, I know that everyone would be interested in .Net performance, but I just don't think it should have been presented in a way that appears misleading.

404 on search function on mysql.com
Hi, For some reason I get a 404 error when I click on 'search' in the Quick links section at http://www.mysql.com/documentation/mysql/bychapter/. It looks like it does some type of redirect so my browser could be broken too, but usually not so much with a 404. :) 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?

Remote access to MySQL
Hi! I want to access various databases on a MySQL server remotely. I've set up an entry in the mysql.user table to allow access to mysql for all hosts in subnet 10.2.107.0/255.255.255.0. First this worked fine. Then my server moved from address 10.2.107.24 to 10.2.107.204. Now I do not have access anymore to any of the databases except on the server itself accessing via localhost. Any idea how to bring this back to work to allow access to whole subnet 10.2.107.0/255.255.255.0 would be appreciated! -- Thomas - 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?

ssl confusion
Hi All, I've been through the list archives and the documentation and have found no good discussion of getting ssl connetions working with mysql 4.

RE: drop down list using php and mysql
Hi,
This type of qustion should be forwarded to PHP-DB list. Its adres is:
[EMAIL PROTECTED] .
As for the answer to your question.. IF you'd like to create a dynamic
drop-down menu.. You can just just query the table for the options to be
displayed and loop through the result set and print them on html .. For
example:
$query=select field from table;
$result=mysql_query($query);
$numrows=mysql_num_rows($result);
echo 'select name=categories';
for ($i=0; $numresult $i; $i++)
{
$row=mysql_fetch_array($result);
echo 'option'.($row[field]).'';
}

RE: drop down list using php and mysql
A correction... for line has the greater sign wrong:) It has to be :
for ($i=0; $numresult $i; $i++)

Hi,
This type of qustion should be forwarded to PHP-DB list. Its adres is:
[EMAIL PROTECTED] .
As for the answer to your question.. IF you'd like to create a dynamic
drop-down menu.. You can just just query the table for the options to be
displayed and loop through the result set and print them on html .. For
example:
$query=select field from table;
$result=mysql_query($query);
$numrows=mysql_num_rows($result);
echo 'select name=categories';
for ($i=0; $numresult $i; $i++)
{
$row=mysql_fetch_array($result);
echo 'option'.($row[field]).'';
}

Re: drop down list using php and mysql
You could also bypass the num_rows entirely...
?php
$query=select field from table;
$result=mysql_query($query) or exit(mysql_error().BR.$query);
echo 'select name=categories';
for ($i=0; $row = mysql_fetch_assoc($result); $i++) {
echo 'option'.($row[field]).'';
}
echo '/select';

Fetching an optional array from an optional column
I'm working on a form that queries by selection in PHP, where a user selects a subject and an optional selection of geographic region to get information. Each database entry will have 2 subject fields, Subject 1 being the main subject and Subject 2 being the cross-subject, and a geographic field, which is optional. A table is set up like this: +--+--+--+--+--+-+ | ID | Organization | URL | SUBJECT1 | SUBJECT2 | Geographic | +--+--+--+--+--+-+ | 1 | Acme | www | Math| English | Canada | | 2 | Loony Toons | www | Comedy | Math| Brazil | ... The idea is that the query will check the database to see if $Subject has a match in either Subject1 or Subject2. The geographic is an optional selection. If I select a country, then that's fairly simple. However, if I select Math as a subject, and left the Geographic option unselected, I want it to select all records that has a match in either Subject1 and Subject2, irregardless of the Geographic option. I tried the following query: SELECT * FROM links WHERE (SUBJECT1='Legislation' OR SUBJECT2='Legislation') AND GEOGRAPHIC = '' But it won't find the above records because the geographic is not a blank field. I could drop the .. AND GEOGRAPHIC part, but then if someone does select a country, it won't take country into consideration. How do I get it to select all records based on the subject, irregardless of the country?

RE: drop down list using php and mysql
Yup Yup , you sure could.. Or you could also use
while ($array_name=mysql_fetch_Array($result)) {..}but for some reason
i always write at least a couple extra lines and use number of rows.. I
guess it is because thats how i learned it first :))

RE: Fetching an optional array from an optional column
Hi :)
Rewrite your query statement as:
$sql = SELECT * FROM links WHERE (SUBJECT1='$formatted_subject' OR
SUBJECT2='$formatted_subject') AND GEOGRAPHIC='.$geographic.%'
ORDER BY ORGANIZATION ASC;
I think it looks like a $geographic% variable:) Let me know if it does or
does not work..
