ORDER BY problems
Hi all, We are running into trouble with slow queries that use ORDER BY and would like some advice. The main question is: are we experiencing data-modelling/index issues or fundamental restrictions of MySQL. Help would be greatly appreciated - see description below. Patrick -- Say we have three tables: 1- contact (contact_id, name) with contact_id as the primary index and another index on name - name is a CHAR. 6717 records. 2- contact_address_index (index_id, contact_id, address_id ) with index_id as the primary index and two other indexes, one on contact_id, one on address_id. 7580 records. 3- address (address_id, city) with address_id as the primary index and another index on city - city is a CHAR. 7071 records. Note that we can have more than one address per contact and that the same address may be shared by several contacts. The following query takes at least 0.5 seconds using MySQL 3.22.30 (7200 results): SELECT contact.contact_id, last_name, city FROM contact, contact_address_index, address WHERE contact.contact_id = contact_address_index.contact_id AND contact_address_index.address_id = address.address_id ORDER BY last_name The same query without the ORDER BY take less than 0.01 second. explain gives: +---++-+-+-+--+--+-+ | table | type | possible_keys | key | key_len | |ref | rows | Extra | +---++-+-+-+--+--+-+ | contact_address_index | index | address_idx,contact_idx | contact_idx | 8 | |NULL | 7580 | Using index | | contact | eq_ref | PRIMARY | PRIMARY | 4 | |contact_address_index.contact_id |1 | | | address | eq_ref | PRIMARY | PRIMARY | 4 | |contact_address_index.address_id |1 | | +---++-+-+-+--+--+-+ on MySQL 3.23.39, a query like SELECT contact.contact_id, last_name, city FROM contact USE INDEX( name_idx ) , contact_address_index, address WHERE contact.contact_id = contact_address_index.contact_id AND contact_address_index.address_id = address.address_id ORDER BY last_name where name_idx is the index on name (contact table) helps but still take 0.16 seconds. It is not a good solution to force the index anyway as if the WHERE of the query is more complicated it may be better to use another index. Using inner join under MySQL 3.23 doesn't help.

Re: AW: MySQL is hogging my box
I assume you've done the slow-query-log review thing... making sure all your
queries are fast, yes?
Yes, you're right. After I did the myisamchk, the box has been more or
less stable with loads from 10 to 15. Still seems a lot ot me. I've
checked slow-query-log and only seemed to have one slow query every 4 or 5
minutes.

Re: Re: MySQL is hogging my box
There are some others with a similar problem(including me). Hi guys. I'd be really interested in knowing things like how many requests, and of what type, are being made of your database(s). If you're making a couple of dozen SELECTs per day, then I'd say that you have a problem, but if you're doing 500,000,000 INSERTs and 1 Bil. SELECTs, then I could see some call for your systems to slow down. Here are my relevant data: Hardware: DualPentium 1GHz with 2GB RAM and a RAID5 HD-Array MySQL: 3.23.37 average of 20 queries/second peak about 40 or 50 Only small tables with a few thousand entries per table now the special: there is a merge table that merges 10 other tables sometimes i access the MyISAM tables, sometime the mergetable about 90% read operations. Sometimes 2-3 times per day the load average raises above 50 in a few seconds and fall back (a bit slower) below 1. During the time of the high LoadAverage i get too many connections errors. It's not traffic depended (well of course it's more often at high traffic times, but it occured in low traffic times, too) as far as i can see. My suspicion is that something is wrong with the mergetable... I set the log-slow-queries and after the describes behavior i can only find queries which accessing the merge table in the slow.log. - 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?

From clause not allowed in update, delete
I am pretty new to mysql, and have been studying the feesibility of offering a mysql version of my product (currently uses ms sql server). Reading a post to this list yesterday, it came to my attention that there is no FROM clause allowed in either the UPDATE or DELETE statements (actually, the DELETE statement has a FROM clause but you can't, as I understand, JOIN tables there). This will pose significant design challenges for me as my app relies heavily on this functionality. So far, I have conceived 2 ways to work around this limitation. 1. Use CREATE TEMPORARY TABLE (...) SELECT (with my join); Then, REPLACE INTO ... SELECT. (Note, for deletes, it would be necessesary to carry a flag field which would be updated using the above process and then DELETE ... WHERE flag = set) 2. Build an app with the C API which will simulate the functionality in two steps. (Note, this would be a pain!) Getting to my question... Surely this gaping whole in the functionality spectrum has inspired the creativity of many in this group. Would anyone care to share the details of solutions they have invented to work around this limitation? - 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: Mysql Daemon starts at boot then Terminates??
Since you failed to check the error log and post it here I can only guess.
chown -R mysql /usr/local/mysql

any HELP!!!

I copied and the mysql.server to /etc/rc.d/init.d/

ln -s /etc/rc.d/init.d/mysql.server /etc/rc.d/rc0.d/K01mysql
Also the end of make install asked me to do the following
something like
mysqladmin -u root -p password = newpassword ('data')
mysqladmin -h mymachine.peer -p password = newpassword ('data')
( I hope I remembered that correctly)
I am baffled my next step will be entries to my.cnf

Subject: Simple SELECT query (or so I thought)
I am running a stats page for our Genome@Home team, and I'm
trying to get a
simple SELECT that will get the data that I need...
Ok, I have a table setup like this:
Genomestats
---
username varchar(255)
curDate datetime
wucount bigint
genecount bigint
updates int
rank int
teamnumberbigint
A sample record from the table may look like this:
|DP | 2001-08-24 16:00:00 | 25786 | 1588 | 1 | 24 |
983928120|
My SELECT looks like this (note that the dates are dynamically generated):
SELECT * FROM genomestats WHERE curDate IN ('$curDate', '$lastUpdate',
'$lastDay') order by wucount desc, rank desc;
Where $curDate is the most recent data update, $lastUpdate is the update
from 3 hours ago, and $lastDay is the update from 24 hours ago. When I
execute the SQL, and print the resulting recordset to my log file, I get
data like this:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 || 983928120

2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 || 983928120
Now, the problem is that the user IronBits had a wucount at somepoint (in
the last 24 hours here) that was less than Zoso's wucount.
Basically, this
means that IronBits passed Zoso sometime in the past 24 hours. I need to
have all of the data grouped by the username, but if I add in group by
username, then I only get one set of records, not 3, as shown above. Here

RE: Simple SELECT query (or so I thought)
I am not possitive that I completely follow what you are trying to do...
but, here goes:
What if you create a temporary table first:
CREATE TEMPORARY TABLE tu (
usernamevarchar(255),
maxwucount bigint,
maxrank int
) SELECT username, max(wucount) as maxwucount, max(rank) as maxrank
FROM genomestats
WHERE curDate IN ('$curDate', '$lastUpdate', '$lastDay')
GROUP BY username;
Then:
SELECT genomestats.*
FROMgenomestats INNER JOIN tu ON genomestats.username = tu.username
WHERE genomestats.curDate IN ('$curDate', '$lastUpdate', '$lastDay')
ORDER BY tu.maxwucount desc, tu.maxrank desc, tu.username,
genomestats.wucount desc, genomestats.rank desc
I've seen the other suggestions telling you to just add the username to your
order by but if I understand your situation this would not work because it
would not satisfy your wish to have the list sorted with the highest
wucount/rank first... right?

If you're using kill -9 on mysqld, stop it. If you're doing things to the table files while mysqld is running, don't. I was reading in the manual that u could up some of the cache sizes, /usr/local/mysql/bin/safe_mysqld --user=mysql -O key_buffer=64M -O table_cache=256 \ -O sort_buffer=4M -O record_buffer=1M Of course, otherwise there'd me no point in having them. If you have a gigabyte of RAM I see no point in not letting mysqld use at least a few hundred megabytes or so just for buffers. //C -- Carl Troein - Círdan / Istari-PixelMagic - UIN 16353280 [EMAIL PROTECTED] | http://pixelmagic.dyndns.org/~cirdan/ Amiga user since '89, and damned proud of it too. - 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?

Dear MYSQL, I Received an Unexpected Error 1034 and am Reporting It
Description: Hello, I've been using MY-SQL with 3 tables, which all have the same primary key = CHAR(2), VARCHAR(50). Everything was fine for several months but yesterday I received an ERROR 1034 in mysql stating that the key file for one of the tables was incorrect. I was able to fix the index with MYISAMCHK but I am reporting this because I do not know why this error occurred. How-To-Repeat: I am not sure if this error can be easily reproduced. I have about 35,000 records in the main table and 7,000 records in the second table, and none in the third. Fix: Use MYISAMCHK as documented on the index files for the tables.

mysqldump problem
Hi The following example gives me a problem. I create a new database by sending the following SQL commands: create database dummy create table `Dummy Table` (`Dummy Time` timestamp(14) NOT NULL) When i run mysqldump with the parameters shown below mysqldump -uroot -pxx -A -a -F -l --opt -rc:/mysql/data/dump.sql I will get a dump file which look like the following section: / # MySQL dump 8.16 # # Host: localhostDatabase: # # Server version3.23.42-log # # Current Database: dummy # CREATE DATABASE /*!32312 IF NOT EXISTS*/ dummy; USE dummy; # # Table structure for table 'dummy table' # DROP TABLE IF EXISTS `dummy table`; CREATE TABLE dummy table ( Dummy Time timestamp(14) NOT NULL ) TYPE=MyISAM; # # Dumping data for table 'dummy table' # LOCK TABLES `dummy table` WRITE; UNLOCK TABLES; / As you can see drop table uses the ` character around dummy table, but don't use it in the create CREATE TABLE statement. The `character is also missing around the colum name Dummy Time. These two things make it difficult for me to restore the database from the dump file so I hope you can give me some advise.

RE: Simple SELECT query (or so I thought)
Well, here is where the problem comes in... Taking the data that I posted:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 || 983928120
junior || 2001-09-14 03:30:00 || 51743 || 3014 || 155 || 11 || 983928120
junior || 2001-09-13 06:30:00 || 51480 || 2997 || 149 || 11 || 983928120
IronBits || 2001-09-14 06:30:00 || 50787 || 3021 || 156 || 12 || 983928120
IronBits || 2001-09-14 03:30:00 || 50712 || 3016 || 155 || 12 || 983928120
Zoso || 2001-09-14 06:30:00 || 50549 || 2917 || 156 || 13 || 983928120
Zoso || 2001-09-14 03:30:00 || 50505 || 2914 || 155 || 13 || 983928120
Zoso || 2001-09-13 06:30:00 || 50188 || 2893 || 149 || 12 || 983928120
IronBits || 2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 || 983928120
The problem still exists that if someone has a wucount at any point that is
higher than anothers. Take Zoso and IronBits for example. On the 13th at
6:30 am, IronBits had a wucount of 50181. But at some point, Zoso had a
wucount higher than that of IronBits. So then, the order by fails to sort
the data in a way that I'd like. Here's how it should look:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 || 983928120
junior || 2001-09-14 03:30:00 || 51743 || 3014 || 155 || 11 || 983928120
junior || 2001-09-13 06:30:00 || 51480 || 2997 || 149 || 11 || 983928120

IronBits || 2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 || 983928120
Zoso || 2001-09-14 06:30:00 || 50549 || 2917 || 156 || 13 || 983928120
Zoso || 2001-09-14 03:30:00 || 50505 || 2914 || 155 || 13 || 983928120
Zoso || 2001-09-13 06:30:00 || 50188 || 2893 || 149 || 12 || 983928120
I need the usernames grouped together, but the data still sorted on wucount.
Ideas?

Subject: Simple SELECT query (or so I thought)
I am running a stats page for our Genome@Home team, and I'm trying to
get a simple SELECT that will get the data that I need...
Ok, I have a table setup like this:
Genomestats
---
username varchar(255)
curDate datetime
wucount bigint
genecount bigint
updates int
rank int
teamnumberbigint
A sample record from the table may look like this:
|DP | 2001-08-24 16:00:00 | 25786 | 1588 | 1 | 24 |
983928120|
My SELECT looks like this (note that the dates are dynamically
generated):
SELECT * FROM genomestats WHERE curDate IN ('$curDate', '$lastUpdate',
'$lastDay') order by wucount desc, rank desc;
Where $curDate is the most recent data update, $lastUpdate is the
update from 3 hours ago, and $lastDay is the update from 24 hours ago.
When I execute the SQL, and print the resulting recordset to my log
file, I get data like this:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 ||

IronBits || 2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 ||
983928120
Now, the problem is that the user IronBits had a wucount at somepoint
(in the last 24 hours here) that was less than Zoso's wucount.
Basically, this means that IronBits passed Zoso sometime in the past
24 hours. I need to have all of the data grouped by the username, but
if I add in group by username, then I only get one set of records, not
3, as shown above. Here is what I want:

Correct. I need the data sorted by the wucount first, but still have the
data grouped together by the username. I don't quite follow the reasoning
behind a temp table. Won't I still have the problems of the sorting, or can
you explain to me how this will solve that problem?

I am not possitive that I completely follow what you are trying to do...
but, here goes:
What if you create a temporary table first:
CREATE TEMPORARY TABLE tu (
usernamevarchar(255),
maxwucount bigint,
maxrank int
) SELECT username, max(wucount) as maxwucount, max(rank) as maxrank
FROM genomestats
WHERE curDate IN ('$curDate', '$lastUpdate', '$lastDay')
GROUP BY username;
Then:
SELECT genomestats.*
FROMgenomestats INNER JOIN tu ON genomestats.username = tu.username
WHERE genomestats.curDate IN ('$curDate', '$lastUpdate', '$lastDay') ORDER
BY tu.maxwucount desc, tu.maxrank desc, tu.username,
genomestats.wucount desc, genomestats.rank desc
I've seen the other suggestions telling you to just add the username to your
order by but if I understand your situation this would not work because it
would not satisfy your wish to have the list sorted with the highest
wucount/rank first... right?

Subject: Simple SELECT query (or so I thought)
I am running a stats page for our Genome@Home team, and I'm trying to get a
simple SELECT that will get the data that I need...
Ok, I have a table setup like this:
Genomestats
---
usernamevarchar(255)
curDate datetime
wucount bigint
genecount bigint
updates int
rankint
teamnumber bigint
A sample record from the table may look like this:
|DP | 2001-08-24 16:00:00 | 25786 | 1588 | 1 | 24 |
983928120|
My SELECT looks like this (note that the dates are dynamically generated):
SELECT * FROM genomestats WHERE curDate IN ('$curDate', '$lastUpdate',
'$lastDay') order by wucount desc, rank desc;
Where $curDate is the most recent data update, $lastUpdate is the update
from 3 hours ago, and $lastDay is the update from 24 hours ago. When I
execute the SQL, and print the resulting recordset to my log file, I get
data like this:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 || 983928120
junior || 2001-09-14 03:30:00 || 51743 || 3014 || 155 || 11 || 983928120

2001-09-13 06:30:00 || 50188 || 2893 || 149 || 12 || 983928120 IronBits ||
2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 || 983928120
Now, the problem is that the user IronBits had a wucount at somepoint (in
the last 24 hours here) that was less than Zoso's wucount. Basically, this
means that IronBits passed Zoso sometime in the past 24 hours. I need to
have all of the data grouped by the username, but if I add in group by
username, then I only get one set of records, not 3, as shown above. Here
is what I want:
junior || 2001-09-14 06:30:00 || 51819 || 3019 || 156 || 11 || 983928120
junior || 2001-09-14 03:30:00 || 51743 || 3014 || 155 || 11 || 983928120
junior || 2001-09-13 06:30:00 || 51480 || 2997 || 149 || 11 || 983928120
IronBits || 2001-09-14 06:30:00 || 50787 || 3021 || 156 || 12 || 983928120
IronBits || 2001-09-14 03:30:00 || 50712 || 3016 || 155 || 12 || 983928120
IronBits || 2001-09-13 06:30:00 || 50181 || 2982 || 149 || 13 || 983928120
Zoso || 2001-09-14 06:30:00 || 50549 || 2917 || 156 || 13 || 983928120 Zoso
|| 2001-09-14 03:30:00 || 50505 || 2914 || 155 || 13 || 983928120 Zoso
|| ||
2001-09-13 06:30:00 || 50188 || 2893 || 149 || 12 || 983928120
But I can't think of a good, simple way to do this. Anyone have any ideas?

Is there a version of MySQL compiles with '-64' option on SGI?
Hi, I am making a program which reads information from the online system and logs them into the MySQL database. The libraries for the other part were compiled with '-64'. However I found that the lib of MySQL client was compiled with '-32'. Thus create linking problem! Is there a version of MySQL lib that is complied with '-64' option on SGI IRIX 6.5?

RE: Simple SELECT query (or so I thought)
Try it and see. What I think you want is to rank your usernames according
to who has the highest wucount and rank and then show the individual records
in descending order of wucount/rank but grouping records by username. This
differs from the suggestion of simply adding username at the front of your
order by in that in that scenario, the records will be sorted alphabetically
by username. If you want to group by username, then you must determine in
what order usernames will print. The solution I have outlined will order
the usernames according to who has the highest (max) wucount and rank.
Within each username group, the individual records will follow your original
order of wucount desc, and rank desc. The only potential problem with this
is that the max(wucount) and the max(rank) for each username may not occur
within the same individual record. You should think about the ramifications
of this and decide if.
Like I said, give it a try... what have you got to lose?

Correct. I need the data sorted by the wucount first, but still have the
data grouped together by the username. I don't quite follow the reasoning
behind a temp table. Won't I still have the problems of the sorting, or can
you explain to me how this will solve that problem?

Subject: RE: Simple SELECT query (or so I thought)
I am not possitive that I completely follow what you are trying to do...
but, here goes:
What if you create a temporary table first:
CREATE TEMPORARY TABLE tu (
usernamevarchar(255),
maxwucount bigint,
maxrank int
) SELECT username, max(wucount) as maxwucount, max(rank) as maxrank
FROM genomestats
WHERE curDate IN ('$curDate', '$lastUpdate', '$lastDay')
GROUP BY username;
Then:
SELECT genomestats.*
FROMgenomestats INNER JOIN tu ON genomestats.username = tu.username
WHERE genomestats.curDate IN ('$curDate', '$lastUpdate', '$lastDay') ORDER
BY tu.maxwucount desc, tu.maxrank desc, tu.username,
genomestats.wucount desc, genomestats.rank desc
I've seen the other suggestions telling you to just add the username to your
order by but if I understand your situation this would not work because it
would not satisfy your wish to have the list sorted with the highest
wucount/rank first... right?

Re: Getting data from Oracle to Mysql
Since I know Oracle, MySQL, and Java the fastest way I did it was: 1) I created scripts for creating the tables in both DBs (this is the way I usually do). They differ a bit on datatypes, and I had to remove all the foreign key when dealing with MYSQL. I have 2 scripts called makeOraDB.sql and makeMySQLDB.sql that will call others scripts and generate the dbs in both environments any time I run them. If I need to update or fix the schemas all I need to do is run the scripts again. 2) I created a class in java to deal with the migration and persistence. This class creates 2 connections one with Oracle and another with MySQL. I read the rows in Oracle into a resultset and then I navigate this result set and for every row I do an insert in the MySQL DB. Notice that this is a one shot process. The MySQL tables are completely empty in the beginning of this process. Notice also that the scripts for generating the DB are used in a development environment. In production it would make no sense dropping and generating the DBs again and again. I am in a development process. If you are in a production environment, with your Oracle DB completely populated with data, you can just work on the MYSQL scripts and the java migration class. In summary: I did everything from scratch, completeluy manually. No tools involved. If someone know a better way please let me know.

RE: Getting data from Oracle to Mysql
What is copy-db utility? Where can I find it? Does it come with MySQL or any other DB? Tell me and I will make use of it, and let you know if there are issues. Today I have 4 dbbases (LDAP, Oracle, SQL Server and MySQL) and I have to keep them with the closest table structure as possible. This means that I have the same tables in all of them. They differ in datatypes (required by the products) but the data is the same for all. Today I have been working with scripts for all relational dbs (it works fine and gives you the whole control of what you are doing). However I would love to try something else.

They differ a bit on datatypes, and I had to remove all the foreign key when dealing with MYSQL. I have 2 scripts called makeOraDB.sql and makeMySQLDB.sql that will call others scripts and generate the dbs in both environments any time I run them. If I need to update or fix the schemas all I need to do is run the scripts again. 2) I created a class in java to deal with the migration and persistence. This class creates 2 connections one with Oracle and another with MySQL. I read the rows in Oracle into a resultset and then I navigate this result set and for every row I do an insert in the MySQL DB. Notice that this is a one shot process. The MySQL tables are completely empty in the beginning of this process. Notice also that the scripts for generating the DB are used in a development environment. In production it would make no sense dropping and generating the DBs again and again. I am in a development process. If you are in a production environment, with your Oracle DB completely populated with data, you can just work on the MYSQL scripts and the java migration class. In summary: I did everything from scratch, completeluy manually. No tools involved. If someone know a better way please let me know.

RAID by itself doesn't mean much. You prorably have to define which exact RAID level you mean. Raid0 (striping), raid1 (mirroring), other raids? Of course, RAID0 can give double speed on whatever disks, RAID1 gives redundancy, and so on.

ODBC Drivers
Hows it going! I have created a mysql database on a windows 2000 platform and have been able to connect, start it as a service, performed all basic SQL statements(insert, update, select, delete) and use it from the command line. I obtained a copy of MySQL from sams teach yourself MySQL in 24 hours. I am a java programmer and I have written a program to access this program. Along with the MySql CD there is a Windows NT driver.zip file I belive I installed that correctly. To Install it I unziped it and followed the steps. After this I went into the controll panel\DataSources(ODBC) and checked the System DNS and added the MySQL database I created at that time I saw an option to choose MySQL as the driver and that is what I selected. What I am confused on is the driver part. Im not sure If I installed everything I needed? What the name of the driver would be??? Do I need to take a class file and add it to my classpath or was that done for me when I installed and ran the Windows NT driver.zip? One of the first things I need to do when running my java program is pass the name of the MySQL driver that Im using. When working with db2 I would add a zip file to the class path and within the zip file would be the ODBC class I need. If you could provide me with some information on MySQL driver setup on windows 2000 I would really appreciate it. Especially the name of the driver class.

HELP PLEASE - C API code help: UPDATE query using result from SELECT
Hi,
I believe that the query below is correct, but I do not believe that it is
possible in MySQL currently due to it not supporting sub-selects:
UPDATE table1 SET ID=table2.ID, Company=table2.Company,
Modified=table2.Modified FROM table1 INNER JOIN table2 ON
table1.Company=table2.Company WHERE table1.Modified='9';
The error produced was:
ERROR 1064: You have an error in your SQL syntax near 'FROM table1 INNER
JOIN table2 ON table1.Company=table2.Company WHERE table1.Modi' at line 1
If you can't tell from the SQL query above...what I am trying to do is
update data in table1 with data from table2...the two tables have pretty
much identical information, although table2 has updated data and table1
can't just be overwritten because it may have something newer than table2
again (this is only part of the entire process which involves two MySQL
servers and a MS SQL server :)
I've read that the only way to do it at the moment is using code such as C
or C++. Does anyone have any experience with this type of procedure?
My code so far is below...my coding knowledge is very weak and this was
obtained from a text:
#include stdlib.h
#include stdio.h
#include /usr/local/mysql/include/mysql/mysql.h
MYSQL my_connection;
MYSQL_RES *res_ptr;
MYSQL_ROW sqlrow;
void display_row();
int main(int argc, char *argv[]) {
int res;
uint i = 0;
query = 0;
mysql_init(my_connection);
if (mysql_real_connect(my_connection, localhost, username,
password, database, 0, NULL, 0)) {
printf(Connection success\n);
res = mysql_query(my_connection, SELECT ID, Modified
FROM table1 WHERE Modified = 9);
if (res) {
printf(SELECT error: %s\n,
mysql_error(my_connection));
} else {
res_ptr = mysql_store_result(my_connection);
if (res_ptr) {
while ((sqlrow = mysql_fetch_row(res_ptr))) {
for (i=0; i
mysql_num_fields(res_ptr); i++)
printf(%s\n,sqlrow[i]);
printf(Fetched data...\n);
/*mysql_query(my_connection,
Some UPDATE code );*/
/*display_row();*/
}
if (mysql_errno(my_connection)) {
fprintf(stderr, Retrieve error:
%s\n, mysql_error(my_connection));
}
}
mysql_free_result(res_ptr);
}
mysql_close(my_connection);
} else {
fprintf(stderr, Connection failed\n);
if (mysql_errno(my_connection)) {
fprintf(stderr, Connection error %d:
%s\n, mysql_errno(my_connection), mysql_error(my_connection));
}
}
return EXIT_SUCCESS;
}
void display_row() {
unsigned int field_count;
field_count = 0;
while (field_count mysql_field_count(my_connection)) {
printf(%s , sqlrow[field_count]);
field_count++;
}
printf(\n);
}
This code works very well in obtaining the data from the tables, but I need
to get a procedure that will perform the UPDATE once the necessary data has
been obtained. In the section
/*mysql_query(my_connection, Some UPDATE code );*/
I have been able to get a static update to work, such as UPDATE table1 SET
Company = 'NewCompany' where Modified = 9, but I need it to input the
values which were obtained from the initial SELECT statement.
I've seen some incomplete code which defines a variable such as query[2048]
and then I assume somehow assigns a query to it which can then be used
similar to:
mysql_query(my_connection, query);
Can somebody please help me get this code completed, as it is going nowhere
awfully fast at the moment.
Thankyou,
John Mravunac

RE: HELP PLEASE - C API code help: UPDATE query using result from SELECT
I am struggling with this myself right now. I posted a similar question to
this group earlier in the day and it must be a poser because no one has
responded.
I fear that the only way to do this with a single sql statement is using the
replace command:
Let's say you have 2 tables like this:
MainTbl
id int not null (primary key),
fld1int,
fld2int,
fld3int
UpdTbl
id int not null (primary key),
fld2int
And let's say that you have 20,000 recs in MainTbl and only 100 recs in
UpdTbl.
You want to join the 2 tables and flag the value from UpdTbl.fld2 into
MainTbl.fld2, right?
The best approach I have thought of is
REPLACE INTO MainTbl
SELECT MainTbl.id, MainTbl.fld1, UpdTbl.fld2, MainTbl.fld3
FROMMainTbl INNER JOIN UpdTbl ON MainTbl.id = UpdTbl.id;
I have not tried this yet but if I read the manual correctly, it should
work.
If anyone has a better solution, please fill us in.
Additionally, I would like ideas on how to work around MySQL's inability to
handle deletes like the following:
DELETE MainTbl
FROMMainTbl INNER JOIN DelTbl ON MainTbl.id = DelTbl.id;

Re: Aborted connection XXX to db.... (Got an error reading communication packets)
Thanks for the reply Jeremy. I keep getting 500 Internal Server error when accessing my database, my application is a C++ development of my own. Smells like Apache to me. Thats what I thought, but on reading Apache docs faq, it mentioned that it is probably the cgi script failure to return proper set of header. So I start rereading my lines of code and check for memory leaks and point of failure, but found none. Then I take out all the MySQL access code and wowla! everything is ok. So I start reading up (and cursing MySQL) and found a possible cause at http://www.mysql.com/doc/C/o/Communication_errors.html I used to suspect memory leaks but thats has been checked with LeakTracer, and passed! What about your Apache error log?

Re: Managing MySQL /w large tables

Is there any tricks/tips anyone can give me for managing large DB's? It also likes to crash tables every month or so to =) Okay First, make sure you're running a recent MySQL version. And try to use the binary distributions available on the mysql.com web site. I was reading in the manual that u could up some of the cache sizes, /usr/local/mysql/bin/safe_mysqld --user=mysql -O key_buffer=64M -O table_cache=256 \ -O sort_buffer=4M -O record_buffer=1M would making any of these bigger help at all? They will help A LOT if your queries use indexes. Make sure your queries are using indexes. I have a 1GB machine and set the key buffer to either between 256MB and 384MB most of the time. And I often use a record_buffer of 16MB or so. Jeremy -- Jeremy D.

Re: MySQL Swapping

I am working with a rather large MySQL DB, it seems that it likes to swap ALOT, even after the operations are done, i have bumped up my cache sizes, i have tones of .bin files in my var dir, any ideas? What OS are you running on? If Linux 2.4.x, you might be running into some of the same problems I saw with the VM subsystem. I posted a note about a week ago describing the problems I've seen. It has since migrated to the linux-kernel mailing list where folks are still trying to tune things correctly. If not, tell us which OS, how much RAM you have, and send along your my.cnf file. Then we can make some informed suggestions. Jeremy -- Jeremy D.

If it's a CGI program, it should be trivial to find the problem--try running it outside of Apache. Does it work? Try running it as the same user as Apache runs under. Does it still work? If so, this really isn't a MySQL problem. Jeremy -- Jeremy D.

Hopeing for kind help Gee, you could probably easily use 100,000 or more if you have ReiserFS or another filesystem that can handle large directories. I'll be impressed if you have anywhere near that many! You see, the limit is not in MySQL, it's in the operating system.

Seriously, though, I don't think anyone knows with much certainty. The 4.0 release has to hit alpha/beta/gamma testing and then be released. That should be starting soon, based on what we've heard here before. You can, of course, offer to sponsor the work on views and it might speed things up...
