If there a maximum connection limit for process ? No. Your process is only limited by your OS. E.g. Linux defaults to a limit of 256 sockets per process. I don't know about Windows. I know but i tried it on 1 GB RAM and dual processor PIII 700 MHZ on winnt 4 with service pack 6 a. There is a concurrent sleeped process limit. Same on linux too also. I think it is abnormal cause everyone is talking about 10.000 Web Hit. Sorry? You can handle 10.000 web hits with only one connection. i am not interested about web. it works. no problem. if you just create a server object on asp. loop the recordset. then close. no problem. cause you only open 1 process then close. and it take 1 secs. example. Think a scenario : You connect via ODBC or Data Environment from VB then you get a recordset. You will show this recordset on a grid. (excel style spreadsheet.) if you use additem method , you can loop recordset and manually add rows into grid then close recordset no problem. but if you bound grid into that dao object then until program or form close it run as a sleep process. and if you even use 3 connection for program , if max sleep process is limited to 90 (due to your hardware configuration , but even if you use 1 gb ram it is limited to max 120) that means maximum 30 user will be execute your program. and it is not satify us. Is it cause from sleeped process list ? Quite probably. Why do you need so much sleeping processes? Maybe there is a misconception about the need of them? mentioned above I increased maximum connection to 200 but it not works. I think it is not related with maximum connection. It is related with maximum process number. Why do you get so much processes? Do you really get so much hits? If so, maybe someone else can help (I have no clue about tuning Windows systems). yes i really need this. as i mentioned above every executed compiled software will be needed at least 3 connection till to unloaded.

Data won't display
Hello, I noticed that while access databases use 'memo' mysql does not. It uses blob. Anyway, I used it for a discussion board, and it stores messages, but it won't display on my web page via asp. It would work via access using 'memo' not 'text'. So what conditions apply when inserting/displaying 'blob' text ( I need text well over 1 characters I figure at times) that I should know about? Anybody notice how text records sometimes don't display?

Re: when does inserting become too much of an overhead?
Daniel Kirk writes:
Hi there,
I am considering porting a MS-SQLServer database to MySQL. After reading
some of the documentation, I am concerned about inserts.
I run a sports prediction website, where players submit their predictions
for a competition. When a player submits their predictions, this is
generally 10 inserts into each of 3 different tables.
It is not feasible to store these inserts in a pool and execute them later -
they must be done so that the player receives confirmation that their
predictions were submitted straight away - their predictions must also be
submitted by a certain time so the time they submitted them must be
accurate.
The website generally gets busy on a friday afternoon as that is when most
people want to submit their predictions. Hence I need the database to be
able to inserts thousands of records per second - how much would MySQL be
able to handle?
Another problem I foresee is that this table is also used for people to view
the predictions of other users. So a common query is something like "SELECT
tip FROM UserTippingInfo WHERE userid = x AND matchnumber = y". Would I be
best to keep the in the one table or should I create a View on the table or
a copy of the table to query?
thx for your help
Dan
Hi!
If you would use multi-row INSERT's, you would be surprised of the
speed that MySQL is capable of.
Regarding SELECT's, you just have to normalize your schema and put
indices to the right place, which in the above situation would be on
userid and matchnumber, without unnecessary duplicating tables. Also
try not to DELETE rows, but to mark them so that INSERT's and SELECT's
could work in parallel (if on UNIX).

Sinisa

But - when I modify the mysql database or create new databases then only the files outside the jail, in /var/lib/mysql/ gets modified. So why there is a need for having this mysql database copy in the jail?!

Since you're using an inner join, the order of joins has no effect on the output. It's purely an optimization issue. The other thing you're asking about is getting all rows from one table and matching rows from other tables. The answer is to use LEFT JOIN, with the main table as the left table.

Re: Problem with Match / Against and multi-table join
I am trying to write a query using the fulltext and match and I've
run into a problem. I'm new to MySQL, so this question might have
already been asked, but I just can't seem to find it.
I'm using the fulltext capabilities to do a query. The query
requires joins with four different tables. The problem that I've
run into is once I add the fourth table, the match column no longer
has any value -- it's always zero. I'm running version 3.23.32 on a
Windows 2000 server machine.
Query 1: Works as expected
select message.thread_id, message.forum_id, message.user_id,
message.created, match message.body against ('test') as score,
thread.thread_title, user.username
from message,thread,user
where message.thread_id = thread.thread_id
and message.user_id=user.user_id
order by score desc limit 10
Query 2: Returns rows (the joins are working), but match column is
zero for every record.
The only difference is the addition of the forum table (adding
forum.title as a column, and adding a join condition in the where
clause)
select message.thread_id, message.forum_id, message.user_id,
message.created, match message.body against ('test') as score,
thread.thread_title, user.username, forum.title
from message,thread,user,forum
where message.forum_id = forum.forum_id
and message.thread_id = thread.thread_id
and message.user_id=user.user_id
order by score desc limit 10
Am I missing the point with all this? Should I be doing a
match...limit x into a temporary table and then do my join against
that?
I would appreciate any help anyone can offer.
Sir, in the example you're not doing anything with the fourth table.
Why are you adding it to the FROM clause?

specifically left out of the field list in the LOAD DATA INFILE statement
as
follows:
LOAD DATA INFILE 'example.csv' replace into table example FIELDS

otherwise TIMESTAMP will be set to the appropriate zero value

Microsoft
Access 2000 using ODBC and MYSQL.
MYSQL Ver 11.12 Distrib 3.23.32, for pc-linux-gnu (i686)
ODBC myodbc-2.50.36-win95
MS Access2000 with MDAC 2.1
The error messages I am getting are "this record has been changed by

I believe it is due to duplicate timestamp(14) values.
For Example:
I have a simple data base created using the following statement:
create table example (id int(11) NOT NULL AUTO_INCREMENT, name
varchar(10),timestamp timestamp(14),PRIMARY KEY(id));
***no problem***
mysql describe example;

| id| int(11) | | PRI | NULL| auto_increment |
| name | varchar(10) | YES | | NULL||
| timestamp | timestamp(14) | YES | | NULL||
+---+---+--+-+-++
3 rows in set (0.00 sec)
***problem***
when I import external data in the following format (example.csv)

| 1 | aa | 00 |
| 2 | bb | 00 |
| 3 | cc | 00 |
++++
3 rows in set (0.00 sec)
The timestamp has not been changed upon import and hence is duplicated
throughout.
***Question***
Is there any way to import from an external source and create a modified
(unique) timestamp upon import ?
I have tried defining the timestamp(14) column with "default 'now' ",
suggested by somone else with a
similar problem but it doesn't seem to work.

Need help debugging 3.23.32 crashing
MySQL 3.23.32 has been crashing on me quite frequently, as well as the past several versions. At first I gave MySQL the benefit of the doubt and blamed it on the compilation. I've since tried 6 different builds, ranging from fully optimized with no debugging to bloated and slow, with full debugging. Each one of the crashes. I know the table that is causing MySQL to segfault, but I can't reproduce yet the sequence of queries that caues it to happen. What I really need help with is instructions on how to make mysqld write its core file after it crashes. I have "core" on its own line in /etc/my.cnf, in the [mysqld] section. Is that enough? Obviously not. I'm new to using the my.cnf the parsing of that file seems somewhat odd. If that is what I'm supposed to do, where are the core files supposed to go? Also, the error doesn't show me a stack trace, but instead says: Bogus stack limit or frame pointer, aborting backtrace. Then, mysqld restarts and I see a bunch of lines like: read_const: Got error 126 when reading table ./livejournal/dirsearchres I've pretty much figured out that MySQL crashes after I do a "DELETE FROM dirsearchres". That table is constantly growing up to a million rows or so, and then a cron job deletes everything in them. (Why this is necessary is another discussion in itself) MySQL developers --- maybe that means something to you. The schema is: CREATE TABLE dirsearchres ( dsid INT UNSIGNED NOT NULL, userid INT UNSIGNED NOT NULL, KEY (dsid) --- really an INDEX, not a key ); The this table grows a ton, then rapidly shrinks. Maybe TRUNCATE dirsearchres would work better than DELETE FROM dirsearchres. But regardless, MySQL is crashing and should be fixed. I don't want to find a workaround. Any suggestions? - Brad - 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?

Different versions causing this?
I recently asked for some help with join order and it's now fixed, kinda :) On a web server running mySQL version 3.22.32 on a Linux box (cobalt RAQ) I get the following output for this query: EXPLAIN SELECT * FROM (LOG_LOG LEFT JOIN SAT_CMD ON LOG_LOG.LOG_ID=SAT_CMD.LOGID) LEFT JOIN SAT_GEN ON LOG_LOG.LOG_ID=SAT_GEN.LOGID; table type possible_keys key key_len ref rows Extra LOG_LOG ALL NULL NULL NULL NULL 41 SAT_CMD ALL LOGID NULL NULL NULL 7 SAT_GEN eq_ref LOGID LOGID 8 LOG_LOG.LOG_ID 1 As you can see it's not an optimal query. Nothing I did could fix it. So I dumped the tables and put them on my local machine running mySQL version 3.23.28-gamma on Win98. This is the output I get now for the same query: +-++---+---+-++--+---+ | table | type | possible_keys | key | key_len | ref| rows | Extra | +-++---+---+-++--+---+ | log_log | ALL| NULL | NULL |NULL | NULL | 41 | | | sat_cmd | eq_ref | LOGID | LOGID | 8 | log_log.log_id |1 | | | sat_gen | eq_ref | LOGID | LOGID | 8 | log_log.log_id |1 | | +-++---+---+-++--+---+ 3 rows in set (0.55 sec) All fields remained the same except for case and all indexes are the same. Is it the different versions causing this or different platforms? Thanks and thanks for the previous help in getting this query working in the first place, Chuck Murison

Re: warning using php
Maybe mysql_result description could help you.
int mysql_result(int result, int row, mixed [field] );
mysql_result() returns the contents of one cell from a MySQL result set. The
field argument can be the field's offset, or the field's name, or the
field's table dot field's name (fieldname.tablename). If the column name has
been aliased ('select foo as bar from...'), use the alias instead of the
column name.
When working on large result sets, you should consider using one of the
functions that fetch an entire row (specified below). As these functions
return the contents of multiple cells in one function call, they're MUCH
quicker than mysql_result(). Also, note that specifying a numeric offset for
the field argument is much quicker than specifying a fieldname or
tablename.fieldname argument.
Calls mysql_result() should not be mixed with calls to other functions that
deal with the result set.
Recommended high-performance alternatives: mysql_fetch_row(),
mysql_fetch_array(), and mysql_fetch_object().
I usualy use mysql_fetch_object($result).

Tru64 4.0F Upgrade
After upgrading an 1000A from 4.0E to 4.0F and successfully running 3.23.29a-gamma for three days I thought I was out of the woods. This BTW was an upgrade from 3.22.xx with the Binary release: mysql-3.23.29a-gamma-dec-osf4.0f-alphaev6.tar.gz. I did the OS and Database at the same time, living on the edge? Compiling mysql C clients using the following cc line failed: cc -o test test.c -I/usr/local/mysql/include -L/usr/local/mysql/lib -lmysqlclient -lm ld: Unresolved: mysql_num_fields mysql_error /usr/local/mysql is my default installation directory. A "ls -l" of the lib directory in /usr/local/mysql/lib has: -rw-r--r-- 1 mysql mysql 369074Feb 4 05:34 libmysqlclient.a I was quite concerned and downloaded the mysql-3.23.32 source and compiled the client library portions using gnu's make (3.79.1). After this successful compilation (It did fail on ./strings doing strxmov.c and the include c_asm.h later on.) and make install from those directories I tried replacing the -L/usr/local/mysql/lib (Binary Distribution Files) with: -L/usr/local/lib/mysql (Source compiled locally.) and it worked. The ls -l of /usr/local/lib/mysql is: -rw-r--r-- 1 root system 455926 Feb 4 18:43 libmysqlclient.a "file" on both says "Alpha archive" My question is this: Is there a `problem' with the 23.29a-gamma-dec-osf4.0f-alphaev6 binary release? The alpha I'm working with is a EV5.6, is this the problem? **Obvious** (I will probably take a crash through the mail lists and dig up the files on successfully building a mysqld from source on 4.0f and give it a try. With GNU make it bailed with the error (above) and I'm sure I've seen this on the list or in the README for info specific to Alpha/Tru64.) In the meantime am I safe to continue to run the binary client/server programs including mysqld from the Binary release? They don't seem to be causing in grief and no errors over three days now...

usage of distinct in a table join query?

The query I'm running shows a number of records returned equal to the number of records in table #2... although they ARE ordered correctly. What am I doing wrong? If there's no way to do what I want I suppose I could keep a list of each item encountered and skip over the next element if it has already been encountered but that seems like a lot of extra unneccessary code.

print $output;
but it doesn't give me any output at all. i'd like to know if there
is any special parameter to use with sth-execute to do this. did i
miss anything here?
A couple of points:
(1) You should really `use strict' in your Perl code.
(2) The return value of $sth-execute is not what you expect. Check
the DBI docs to learn what it really is.

Re: sth-execute - screen/file output
You are just missing a step. The execute method does exactly what it says,
executes the prepared SQL statement. Once this is done, you must fetch data
from the handle with one of the fetch methods such as fetchrow_array or
fetchall_arrayref. Another alternative is to combine the prepare, execute,
and fetch into a single statement with one of the operations on a database
handle such as $dbh-selectrow_array(sql statement), etc. There are a few
ways to actually fetch the data, I'd suggest taking a look at the
documentation.
