Re: Query Question
Hi, Since you have over 10,000 member ids it depends on the exact appln that you have. If the length of the SQL query increases above a certain length (i am not sure abt the exact figure), an error is thrown saying query too complex. such wont be the case in your former method. but, if there are n member ids to be updated, the former update query will have to be executed n number of times, giving n disk accesses from your VB program, while the later query would need just 1. So if you can guarentee that the query string will not become too long, then the later update statement is good. If you are not sure, its better to go for the former update stmt and forget abt disk write time(at least ur program wont crash). -Sagar __ Do You Yahoo!? Yahoo!

Re: MERGE Tables
Hi, Ok, the first bug (incorrect COUNT, etc. for MERGE and individual tables) was fixed some time ago. Though, it is possible that you found another bug, the probability is low. I thought I might be encountering actual bugs in the code in my 3.23.32 version. I'd taken a look at the changelog to see if any fixes seemed to apply to this situation, but it wasn't very clear. As for the second - ALTER TABLE ... UNION = () is absolutely legal syntax and MySQL does support it (if you have source distribution, look at mysql-test/t/merge.test). So, let's upgrade now, and then we'll see. I had no doubt it was supported - so I knew MySQL must've been lying when it said it didn't support that operation... :) I assume this has been fixed also in later versions, yes? So, it looks like I need to upgrade my server. I've just been looking at the changelog again and I notice there are some entries for 3.23.38 - is there a new release imminent? Should I wait for this, or just upgrade to 3.23.37 now?

Re: What can I do to help the mysql developers to get mysql to work on OS X?
[EMAIL PROTECTED] writes:
So, I'd really like to have mysql working on OS X and while there were a
few people trying it out and having difficulty, I have yet to see any
posts of total success.
I'm an experienced MacOS programmer, but I have little experience on
Unix -- so I'm way behind the curve on looking at the source and
figuring it out. My only thought is to try to dive in and run mysqld
via gdb and then try to figure out the source tree sufficiently to see
where the shutdown (HUP?) message is getting handled and then set a
breakpoint to see if that code is ever getting called and watch where it
gets stuck by tracing from there.
Unfortunately, I don't know how to use gdb (yet), and there is a LOT of
source to slog through to find where the shutdown code is.Perhaps a
more experienced unix hack could recommend some starting places; perhaps
someone more experienced with the mysql source could point me to the
locations of signal handling code (I hope it's not too obvious, since I
haven't even looked yet... :-( Got to get gdb working first... ).
So, if there is something I can do here to help get the issues resolved,
I'd like to do so. Please feel free to email me directly with
suggestions, staring points etc., if that helps.
Thanks,
Tyler
[EMAIL PROTECTED]
P.S. The problems I have seen posted and experienced myself are:
1) the small edit to get it to compile (not a big deal, but should get
fixed)
2) The mysqld cannot be stopped short of kill -9
3) trying to use mysqladmin shutdown to stop mysqld (and safe_mysql)
fails (hangs, requires kill -9 to halt)
4) the tests do not work.
4a) make test fails
4b) mysql-test-run fails
Hi!
Yes, you can help MySQL being better ported to OS X.
You should first learn to use gdb ... ;o)
It is truly not so difficult.
There are also some GUI interfaces for it. I do not know which ones
work on OS X.
Regarding a diff to make it compile, if you have not sent it to us,
please do.
Regarding second and third problem, you should take a deeper look at
OS X signals and try to see what goes on. Signal handling is all done
in mysqld.cc in sql/ subdir.
Regarding failing tests, you should examine the error log.

Sinisa

Re: MATCH AGAINST 2-3 tables
You need to add the table joining information the the where clause so
the join only returns properly joined records.
EX: where ta.id=tb.id
Paul Van Slyke wrote:
Thanks for the response!
The two tables contain different types of information which are related
by a foreign key (orginally designed that way).However, there is no
reason that there can't be a single table that contains both (actually 3
seperate tables) sets of data. Unfortunately, building the
FULLTEXT index on the third table is incredibly slow on tables sizes
500Megs or more.
So, it sounds like we don't have much of a choice. Your suggestion to
have one table for the FULLTEXT searches seems the best way to go.
What we decided to do is to compile mysql-4.0, build a combined table of
the three (which will be over a GIG) and index it under 4.0. Then move
the tables over to 3.23 for production use.
Thanks! Off to compile 4.0!
Paul
I've got two seperate tables that I would like to query using a MATCH
...
AGAINST() syntax.
Why are they two separate tables?
If I run the query individually on one table, the
speed of the returned results is great! Very fast, indeed. However,
when I try and use the following statement for querying both tables at
the same time, it is painfully slow. Too slow to use in a production
environment.
SELECT DISTINCT * from tA, tB WHERE MATCH tA.aName AGAINST ('name') ||
MATCH tB.bName AGAINST ('name');
You are doing a join between two tables. This means that if table A
has 100 matches and table B has 400 matches, you get 40,000 results
(before applying DISTINCT). *SLOW* !!!
I don't know the structure of your tables, but if they are identical,
why aren't these in one table (with an extra column for which table
they belong in) ?
The fast queries are
SELECT DISTINCT * from tAWHERE MATCH tA.aName AGAINST ('name');
SELECT DISTINCT * from tBWHERE MATCH tB.bName AGAINST ('name');

Re: Help MySQL on website...
Well, if you have to ask, then you are not ready. You need to discuss this with your ISP. Thay may have an implementation doc that shows you what you need to do. In the mean time, get a box, Linux, MySQL, Apache, and PHP. Read the manuals on all these, and pay special attention to the apache installation instructions. You may want to buy one of the Web-in-a-box packages that walk you through it. At any rate you have some reading to do. Mads Andersen wrote: Hi can anyone, please help me!!!

Re: Is my table hosed?
Stop the server, then myisamchk the index. Carina C. Zona wrote: MySQL 3.23.33: This morning, one of my tables suddenly reported index corruption. I locked the table, fixed with myisamchk -o, unlocked, and thought the problem was solved. But it keeps on re-corrupting (I'm not even writing anything to it first). Plus any query on that table which uses a where clause takes an *extremely long time to execute. Queries that normally take .01 seconds are taking 10-15 *minutes*. Or more. DESC TABLE shows that the indexes are all still in place. I even tried dropping and re-creating an index, but that didn't seem to make a difference. EXPLAIN on the queries shows that MySQL still knows to use the indexes that are there. Yet obviously something is quite wrong. One other odd thing: after one of the (many) repair operations, I started getting disk quota filled errors. It turned out that a 142M file with the prefix #sql had surfaced in /tmp. I deleted it, and things went back to semi-normal after that (everything working, but the table still extra slow). Where did that big file come from? My whole db is only 8M, the corrupted table is only 4M, so does it sound right that a 142M temp file was somehow generated..? Odd. Anyway, I'm hoping someone recognizes this problem and can point me toward the right section of the manual to learn how to fix it. fingers crossed that the table is still recoverable...

Re: ORDER BY DESC optimization
First, you don't have an index on 'b', and second, you don't have 'b' in the where clause, so it would not use it if it had one. It needs to sort the result set before it can apply the limit. ryc wrote: I have a fairly large table (greater than 4mil rows) that I would to preform a query like: SELECT col1,col2 FROM table WHERE a=1, c=2 ORDER BY b DESC LIMIT 50; I have an index on the table INDEX1( a,b,c ); When running the query as is, it takes around 4seconds. If I omit the DESC part the query runs in a fraction of a second. I would like the query to run faster when I use DESC. I looked at myisamchk -R to sort by the 'b' index but I want to be sure it will speed up my query since it may take a while to sort all 4million rows.

Empty Set Query question
Hello everyone. I am new to this list and hope it's the right one for my question. This may be really obvious, but I can't seem to figure it out...so here's the problem: I have a table that stores network incident report information, IP address, dates, type of incident, report name, etc. I am trying to query the table for a specific ip address that's in the source_ip field. I can see that the record is there when I query all of the records, but when I query for one specific ip, I get the empty set result! :( Here is my query select * from IDReport where source_ip=xxx.xxx.xxx.xxx; The field type is char(16). Any ideas why mysql is not finding that record?? I appreciate ANY help on this matter!!! :) Thanks, Erica -- Erica B.

Re: problem
Your mysql database (a system db with the access privileges) has a table called host which has amongst other files, one called host.frm It seems that mysqld doesn't have permission to read this file. Check that the mysqld owner and this file's owner are the same and change accordingly. regards, thalis p.s. in general do a: $ perror error_code to see what the error you are getting means.

Re: newbie question on variable length records.
This is straight from 7.7.1 of the MySQL manual: * If any column in a table has a variable length, the entire row is variable-length as a result. Therefore, if a table contains any variable-length columns (VARCHAR, TEXT, or BLOB), all CHAR columns longer than three characters are changed to VARCHAR columns. This doesn't affect how you use the columns in any way; in MySQL, VARCHAR is just a different way to store characters. MySQL performs this conversion because it saves space and makes table operations faster. See section 8 MySQL Table Types. * http://www.mysql.com/documentation/mysql/bychapter/manual_Reference.html - TIM FRASER Hi, I am a newbie to Mysql. I would like to know how to create a table with variable length records? i have an object with following variables: varchar v, int a, int b, int c. and i want to store variable number of such objects into the rows. varchar v is the primary key. the entries in the table would look like: v11,a11,b11,c11,a12,b12,c12,a1,b13,c13 v21,a21,b21,c21,a22,b22,c22 Can you please help me with my problem?

RE: trouble installing mysql rpm on Linux
I installed only mysql-3.23.32-1.7.i386.rpm -- at ftp://ftp.redhat.com/redhat/linux/7.0/en/os/i386/RedHat/RPMS/ there is no mysql-client, so I thought maybe the client was included in the same package. Now that you mention it, I just noticed that in the 7.1 directory there is a mysqlclient9-3.23.22-4.i386.rpm, as well as a newer version of whatever I had before, mysql-3.23.36-1.i386.rpm. There's also a mysql-server-3.23.36-1.i386.rpm, which makes me think the other does indeed contain both client and server. Anyway, I'll give those a try... What is this post installation you mention? Where are those steps documented? I'll re-check the mysql docs, but from what I read earlier it looked to me like with an rpm all I had to do was install. Obviously I'll have to set up some users and such, but I thought at least the daemon should be running. Thanks for your help.

Re: Empty Set Query question
You are doing a text compare, and they have to match exactly, including leading zeros after the dots. You might look at storing them as integers. MySQL has to functions INET_ATON() and INET_NTOA() to convert them back and forth to strings. Erica B. Tanner wrote: Hello everyone. I am new to this list and hope it's the right one for my question.

Any ideas why mysql is not finding that record?? I appreciate ANY help on this matter!!! :) Thanks, Erica -- Erica B.

Re: Problem with LAST_INSERT_ID();
This works for me. You will have to translate the javascript to whatever you are using
...
SQL = insert into myTable(field2, field3, field4) values(dat2, dat3, dat4)
var dataConn = Server.CreateObject(ADODB.Connection);
dataConn.open(MM_soCalData_STRING);
var rs1 = dataConn.Execute(SQL); // Here my record is inserted
rs1 = null;
SQL = select field1 from myTable where field1 = last_insert_id(); //field1 is the
auto_increment field
var rs2 = dataConn.Execute(SQL)
if (rs2.Eof==false){
lastIDvar = rs2(field1);
rs2 = null;
}

But the following 'select LAST_INSERT_ID()' return zero :-((
Weird. I've used them often (on ISAM tables) and it works just fine.
Do you use the same connection for the 'LAST_INSERT_ID' query as for
the INSERT query? The LAST_INSERT_ID is kept per connection and until
another INSERT is done.
Regards,
Fred.
What does your INSERT query look like? It should specify NULL
for ID_ordine, e.g.:
INSERT INTO ordinit(ID_ordine, Cod_Cliente) VALUES (NULL, 10);
Any other value for ID_ordine will not assign an auto_increment
value.

Re: newbie question on variable length records.
I think he may be trying to put a variable number of *fields* in each record. This of course cannot be done directly. If that is what he wants he will need to have his own program merge/parse the data into a fixed number of MySQL fields (columns). On Tue, May 01, 2001 at 09:53:21AM -0400, Tim wrote: This is straight from 7.7.1 of the MySQL manual: * If any column in a table has a variable length, the entire row is variable-length as a result. Therefore, if a table contains any variable-length columns (VARCHAR, TEXT, or BLOB), all CHAR columns longer than three characters are changed to VARCHAR columns. This doesn't affect how you use the columns in any way; in MySQL, VARCHAR is just a different way to store characters.

Re: bug report
For over a year the topic of mathematical operations on date values
has been disussed. It has never been possible to perform such math
on a date value without using DATE_ADD or converting the to days or
seconds first.
Why is this now all the sudden a reasonable bug?
Aurelian:
I suggest that you use DATE_ADD, I'm quite sure what you have found
is not a bug
20010501 - 1 = 20010500
MySQL sees CURRENT_DATE as the value 20010501 and performs your subtraction
as requested, if you want to subtract a day from today I suggest
DATE_ADD( CURRENT_DATE, INTERVAL -1 DAY )
Or the previously suggested TO_DAYS, FROM_DAYS method.

Re: ORDER BY DESC optimization
I have a fairly large table (greater than 4mil rows) that I would to preform a query like: SELECT col1,col2 FROM table WHERE a=1, c=2 ORDER BY b DESC LIMIT 50; I have an index on the table INDEX1( a,b,c ); When running the query as is, it takes around 4seconds.

I looked at myisamchk -R to sort by the 'b' index but I want to be sure it will speed up my query since it may take a while to sort all 4million rows. To improve things I'd suggest you drop the (a,b,c) index and create two new ones: one on (a,c) and another on (b) and then do the myisamchk -R on the second index You might also consider the --sort-records=# option The reason I decided to use (a,b,c) as the index is because I read in the How mysql uses indexes (http://www.mysql.com/doc/M/y/MySQL_indexes.html) that with the index (a,b,c) if you have a where clause where a=constant and have order by b (the key_part2) it will use the index. I may be wrong, but if I have an index just on (a,c) and a seperate index on (b), the b index will span the whole table (greater than 4 mil rows) and thus the cardinality is higher, while (a,b,c) would only span the rows that I am looking for making the query faster. If this isnt right, I will go ahead and try the other index method. The only reason I wouldnt just do it is changing the indexes on the table takes quite a while. What I forgot to include in my first post reguarding the optimization of the order by, when the query contains ORDER BY b DESC, explain says it will use file sort (and hence the query takes around 4 seconds). When I drop the DESC part from the ORDER BY clause, explain no longer says it will use file sort and the query takes .1 seconds or so. I would like the DESC case to be faster as that is the query I need to use. Is --sort-records the option with myisamchk I want or --sort-index?

My only thought is to try to dive in and run mysqld via gdb and then try to figure out the source tree sufficiently to see where the shutdown (HUP?) message is getting handled and then set a breakpoint to see if that code is ever getting called and watch where it gets stuck by tracing from there. Unfortunately, I don't know how to use gdb (yet), and there is a LOT of source to slog through to find where the shutdown code is.Perhaps a more experienced unix hack could recommend some starting places; perhaps someone more experienced with the mysql source could point me to the locations of signal handling code (I hope it's not too obvious, since I haven't even looked yet... :-( Got to get gdb working first... ).

Re: LAST_INSERT_ID returning 3 rows?
Ok I was thinking that you had to tell LAST_INSERT_ID the table you wanted
to get the last insert id from. What if you run a web site and you have 10
tables in a database, how can you tell what the last insert id of table 6
was?
Thanks,
Graeme
Because you included a from clause, you got one line for each row
of 'outages'
Leave out the from outages

Is it possible?
hi, I was reading the manual for the full-text search. It is really interesting to have a search engine embedded into the database itself!!!. Mysql uses the criterias defined by the mysql developers. Is it possible for the user to specify the the criteria in his/her program and mysql rank the results accordingly. If not, is anything like that on the mysql developer's agenda? This would of course need a highly plug and play architechture. This would ease off the work of people(like me) who are working on search engines. -Sagar A. Tamhane __ Do You Yahoo!? Yahoo!

mysqlimport and Optionally Enclosed By spec
Hello, Has anyone experienced and/or solved this problem on a Linux / Apache / MySQL system? I'm trying to call mysqlimport remotely over CGI using perl's system command, to upload and import csv files. Basically everything works except for setting the '--fields-optionally-enclosed-by' argument, which I want to set to (doublequote), as Excel puts them round any field containing a comma. The full command is: mysqlimport --verbose --fields-terminated-by=, --fields-optionally-enclosed-by='' mydb myfilename It just gives up after the first row with a comma in it, after trying to put the whole of the remainder of the csv file into the one field. Any ideas? Thanks in advance, Vyv Hope-Scott 377a St Margarets Rd Twickenham TW1 1PP h 020 8744 2488 m 07768 660 247

When I look at the logs, the last thing in each log is:

or
2 Shutdown
The .err files say the following:
Both errors are actually pointing to the same problem with signals.
So, I guess that there is perhaps only that one problem with the
shutdown signal getting handled properly. ???
I'll work on looking at that then.
Yes.

hi. your table looks something like this: table1 - date(date) order_number int(6) ...i wasn't sure if order_number is referring to a order table somewhere... if there are multiple rows for each day, and you want to add up order_number for each day, use: select DAYOFMONTH(date) as d, SUM(order_number) from table1 group by d if you want to count the rows per day (which i think is what you're after), use: select DAYOFMONTH(date) as d, count(order_number) from table1 group by d you probably want to add in a where clause where MONTH(date) = 4 to limit the rows to all days in april, for example. hth. -ravi. -Original Message- From: Graham Nichols [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 01, 2001 11:23 AM To: [EMAIL PROTECTED] Subject: Newbie group/count query question I have a table which contains a date column and an order_number column.

column count doesn't match and updating 2 tables
I have 2 tables with identical structures. The following sql statement works fine: insert into table_2 select * from table_1 but if I attempt to say insert into table_2 select fieldname_1 from table_1 or any combination of selecting specific fields to be put into the other table, I get an error which is column count doesn't match value count at row 1 I suspect this has something to do with an auto-increment ID field and/or a primary key on ID. Does anyone know how I can overcome this? I have also used replace into table_2 select * from table_1 with the same problems. what I am ultimately trying to do is to have one table go and get certain information from the other table to update itself from the other table. I don't really want to dump all fields from one into the other. Thanks for your help
Re: ORDER BY DESC optimization
On Tue, 1 May 2001, ryc wrote: I have a fairly large table (greater than 4mil rows) that I would to preform a query like: SELECT col1,col2 FROM table WHERE a=1, c=2 ORDER BY b DESC LIMIT 50; I have an index on the table INDEX1( a,b,c ); When running the query as is, it takes around 4seconds. If I omit the DESC part the query runs in a fraction of a second. I would like the query to run faster when I use DESC. I looked at myisamchk -R to sort by the 'b' index but I want to be sure it will speed up my query since it may take a while to sort all 4million rows. To improve things I'd suggest you drop the (a,b,c) index and create two new ones: one on (a,c) and another on (b) and then do the myisamchk -R on the second index You might also consider the --sort-records=# option The reason I decided to use (a,b,c) as the index is because I read in the How mysql uses indexes (http://www.mysql.com/doc/M/y/MySQL_indexes.html) that with the index (a,b,c) if you have a where clause where a=constant and have order by b (the key_part2) it will use the index. This is correct, but that way the 'where a=1 AND c=3' clause would use the index only for the a=1 condition and would do an exhaustive search to find which of those rows also have c=3. This is why I suggested the (a,c) index as a better alternative for your where clause. The reason why I suggested an index on (b) by itself is for the soring of the results. BUT I don't know whether mysql will utilize this index to sort the temporary results or whether only one index can be used from the beginning till the end of a query. Anyone a bit more experienced willing to lend a hand here? If the second index is not used for the sorting, then since both your 'where' conditions are using constants (a=1 and c=3), the optimal index for you is on (a,c,b). cheers again, thalis - 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?

Dates not compared properly?
Howdy all... I've run into a strange date problem as of midnight, May 1, 2001 on my i686 Linux machine running mySQL 3.23.37. For some reason, queries can no longer compare dates properly: mysql select count(*) from hit where date NOW()-1135560; +--+ | count(*) | +--+ | 2633 | +--+ 1 row in set (2.05 sec) mysql select count(*) from hit where date NOW()-1145560; +--+ | count(*) | +--+ |0 | +--+ 1 row in set (2.05 sec) mysql select NOW()-1135560,NOW()-1145560; +++ | NOW()-1135560 | NOW()-1145560 | +++ | 2001057384 | 2001047384 | +++ 1 row in set (0.00 sec) mysql describe hit; ++--+--+-+-+---+ | Field | Type | Null | Key | Default | Extra | ++--+--+-+-+---+ | dig_id | int(10) unsigned | | MUL | 0 | | | date | timestamp(14)| YES | | NULL| | | ip | varchar(16) | YES | | NULL| | | site | varchar(255) | YES | | NULL| | ++--+--+-+-+---+ NOW() is being expanded properly, yet for some reason the comparison of hit.date with NOW()-n fails when n is larger than an abitrary number. As it becomes later and later in the day, n becomes larger and larger (so eventually it will reach 1970 and everything will work again). I've optimized the tables, but don't really have any other good ideas. For now, I'm just doing select count(*) as hits, substring(date,1,8) as foo from hit where ip NOT like x.x.x.% AND ip != x.x.x.x group by foo order by foo desc limit 10; to get the count of most recent hits instead of the faster select count(*) as hits, substring(date,1,8) as whee from hit where date NOW() - 1000 AND ip NOT like 64.5.98.% AND ip != 141.142.22.95 group by whee order by whee desc; Any ideas?

Re: column count doesn't match and updating 2 tables
Hi Suzanne, When you say: insert into table_2 select * from table_1 alls fine. All the records and fields will get copied. But when you say: insert into table_2 select fieldname_1 from table_1 you are just selecting fieldname_1 from table_1 while table_2 consists of fieldname_2 also. So the correct sql statement will be: insert into table_2(fieldname_1) select fieldname_1 from table_1; The fieldname_2 will get its default value and if it is an autoincrement field then the value will be incremented and auotmatically inserted. Hope this will clear your doubt. -Sagar A. Tamhane __ Do You Yahoo!? Yahoo!

mySQL Hangs with Status 'D'
I have been having repeated problems with mySQL 3.23.36 on Linux (Red Hat 6.0, 2.4.3 kernel). I think I've got traced the problem but I don't know how to fix it... At some point after being started one or more of the mySQL threads hang with the ps status of 'D' (my research suggests this can mean something disk related or not). At that point mySQL is totally hung. It won't respond to new connections, thus basically hanging all my Apache sites that use it. Trying to launch 'mysqladmin' just hangs forever trying to connect. The only solution is a restart. Processes with status 'D' cannot be killed. What can I do about this? I've had to restart this server twice today and it's a production Web server. Not fun.

perl DBD make test errors??? Please Help (PROBLEM SOLVED, I think...)
I actually read the readme for DBD ;) and found what looks like the cause of the problem below: The Error means... that your linker doesn't include libgcc.a. You have the following options: a) Either recompile Perl or Mysql, it doesn't matter which. The important thing is that you use the same compiler for both. This is definitely the recommended solution in the long term. b)A simple workaround is to include libgcc.a manually. Do a make clean and make and in the output wait for a line like LD_RUN_PATH=/usr/lib/mysql:/lib egcs -o ../blib/arch/auto/DBD/mysql/mysql.so -shared -L/usr/local/lib dbdimp.o mysql.o -L/usr/lib/mysql -L/usr/lib/mysql -lmys qlclient -lm Repeat the same line in the shell by adding -L/usr/lib/gcc-lib/i386-redhat-linux/gcc-2.7.2.3 -lgcc ***QUESTION: I'll opt for the recompile Mysql. Perl was intalled from the RedHat install CD, Mysql I installed from the tar.gz file. I beleive I'll recompile Mysql - do I use and rpm to do this?

table corruption endemic

Optimization of MySQL
Hi, I am running a MySQL server on a nice machine (dual pIII 1gHz/1g ram), with RedHat 7.0. Currently, I am using the rpm version of mysql, which is 3.23.37. Our database is large, and getting larger, with several tables approaching the 1gig mark. In addition, the database will be moving to a dedicated node on a beowulf cluster. This node is compareable to the machine described above. For our users, we are not particulary interested in squeezing every last drop of performance out of MySQL, but I would be interested to know if there are obvious things that I should do to optimize our performace. For example, compiling my own mysql with certain flags, or perhaps startup options, etc. I searched the usenet and mysql site, and found some information but would like to hear some experienced advice before I jump in with both feet.

how does a user set his own password in mysql? I have searched through the archives, and have found only the 'st password..' command. this does not work. In my case, there are more then just one host in the user table and the set password command only changes the localhost entry, leaving me unable to connect with the new password form other hosts! how do I solve this? Any help would be appreciated. Thanks.
Apache/PHP/MySQL - processes multiply until about 30, then doom
I am running MySQL (3.23.27 at this point) with Apache1.3.12 and PHP3 on a PC running Redhat 6.0. My problem has survived upgrades of all components from earlier versions. Every PHP page has at least one query to a MySQL database for session tracking (home-rolled code, not PHPLib or anything off the shelf) There are also on some pages other queries, to a different database, same server (same mysql). Most of the latter are Phorum queries. Periodically the number of mysql instances that show up in 'ps auxww'1 gets to about 30 and mysql no longer listens to PHP/Apache. However I can still use the mysql shell with no problem, so MySQL is still running but can't hear anything from PHP. The only way to fix it is to run 'apachectl restart' or equivalent. 'graceful' doesn't do it. Im not sure if restarting MySQL instead works. After Apache is restarted, the mysql processes are down to 3 and everybody's happy again. I have been trying for months to figure out what is happening and how to fix it. I had heard at one point that there was a problem with Redhat 5.2 kernel that caused a similar problem, but I upgraded that but no joy. Temporarily I have built a kluge cron job that restarts apache every so often, which worked as long as the server was low volume. But now usage is dramatically increasing due to some new web sites that have been installed and announced to the entire corporation. So the problem is triggered before the restart cleans up the mess. I can't have it restarting every 20 minutes. I've also changed every instance of pconnect() to connect() where I can, but no difference. Can anybody tell me anything useful? I'm supposed to come back with a firm fixit schedule tomorrow morning, so please email me directly as well as on the list - I'm afraid I'll miss it in the volume on the list. If I don't get this fixed very shortly my consulting contract with this company will no doubt begin to fade out!!

RE: mySQL Hangs with Status 'D'
Upgrade to 2.4.4. 2.4.3 had some rwsem issues. -- Vibol Hou KhmerConnection http://khmer.cc -Original Message- From: Hunter Hillegas [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 01, 2001 2:20 PM To: mySQL List Subject: mySQL Hangs with Status 'D' I have been having repeated problems with mySQL 3.23.36 on Linux (Red Hat 6.0, 2.4.3 kernel). I think I've got traced the problem but I don't know how to fix it... At some point after being started one or more of the mySQL threads hang with the ps status of 'D' (my research suggests this can mean something disk related or not). At that point mySQL is totally hung. It won't respond to new connections, thus basically hanging all my Apache sites that use it. Trying to launch 'mysqladmin' just hangs forever trying to connect. The only solution is a restart. Processes with status 'D' cannot be killed. What can I do about this? I've had to restart this server twice today and it's a production Web server. Not fun.

Problem with mysqldump....
Hi everyone, I'm trying to backup all the databases from Server_A to Server_B. I'd issue mysqldump command in server_A to backup every single database, as below :- mysqldump -uusername -ppassword databases_name file_name In server_B, i create a new database using the command below :- mysqladmin -uusername -ppassword create database_name Then... i issued another mysqldump command to put everything back to server_B, as below:- mysqldump -uusername -ppassword databases_name file_name Problem happened where the databases being backup are all empty!! No tables being copied!! Anyone have idea on this?
Re: Problem with mysqldump....
Dont use mysqldump to import. Use mysql. I can't remember the exact syntax, but reference mysql.com for mysqldump, then in the syntax example for that, they show you how to import it.

very easy update, but how? Novice here
What is the syntax for UPDATING the results of this select statement? I am using mySQL 3.22.27 select service.servdef from service, account, user where account.number=user.account and user.number=service.user and (service.servdef = 1) and (account.customerof = 6 or account.customerof = 7 or account.customerof = 8 or account.customerof = 9 or account.customerof = 10) There are 4860 lines that result from this select statement. I want to be able to test an UPDATE statement and make sure that it works before it is applied to the database. Sorry for the newbie question, but I am having a hard time finding a good example doc or text for SQL syntax. I don't know the syntax for the update. Please help. Thanks.

Re: Optimization of MySQL
On Tue, May 01, 2001 at 04:46:39PM -0700, Bryan Coon wrote: Our database is large, and getting larger, with several tables approaching the 1gig mark. In addition, the database will be moving to a dedicated node on a beowulf cluster. Cool... :-) For our users, we are not particulary interested in squeezing every last drop of performance out of MySQL, but I would be interested to know if there are obvious things that I should do to optimize our performace. For example, compiling my own mysql with certain flags, or perhaps startup options, etc. I searched the usenet and mysql site, and found some information but would like to hear some experienced advice before I jump in with both feet. Well, just wait a few weeks for my article in the next issue of Linux Magazine. :-) But before that happens, here are some ideas... There are two approaches to optimization, and you should use both. First is optimizing your application. This is generally just making sure your queries are fast (well indexed), you're only retrieving the data you need, you aren't indexing columns which will never benefit from indexes, you're caching data in your app which can be cached, etc. Second is server tuning. You can look at increasing the size if the key_buffer, record_buffer, and so on in your /etc/my.cnf (or similar) file. Try to get an idea how efficient things are currently. I often use mytop (http://public.yahoo.com/~jzawodn/mytop/) to gather some info about my system before, during, and after tuning. It doesn't give you everything you'll need (yet!), but it's a decent start. You'll probably want to look closely at the output of SHOW VARIABLES and SHOW STATUS and learn more about what some of them mean. And, of course, we're glad to field specific questions on this list. (This reminds me... I'm thinking of another patch to the MySQL manual which explains some more of this stuff. Just need to find the time to do it. Things are getting more, uh... interesting as the number of table handlers expand. With ISAM, MyISAM, InnoDB, BDB, Gemini, and HEAP, there is more room for both improvement and error.)
