Collapsing queries
Hello, I am relatively new with MySQL (and SQL for that matter) and I couldn't find much reference to my problem in earlier posts. Let's say I have 2 tables, CONTENT: msg_id, msg_text ADDRESS: msg_id, address and I receive the msg Hello World addressed to the twins Foo and Bar. now my tables look like this: CONTENT: 1 Hello World ADDRESS: 1 Foo 1 Bar I am desperatly looking for a sql statement that would produce 1 | Hello World | Foo, Bar Is there such a thing??

Try this: SELECT * FROM content, address WHERE content.msg_id = address.msg_id If I understand what your asking for, you want a JOIN.

Re: MySQL 4
Hi I am not sure if you mean what I am thinking you mean. Lets say you have several input fields and you only want the output where ALL entries apply, you can manage that with the IF(match...against(), IF(match...against,0,0),0,0) -something like that - clause. At least thats worked for me. Its a bit messy but I am sure you could get it to work even if you have only one input field: you just need to make up a spacer and get the seperate words in the input (ie you could use + as spacer and then use explode() function). If this sounds confusing or you need more details let me know and Ill send an example of my select query.

Regarding non-functionality of query in mysql under linux
Respected Sir,
I am working as a System Analyst for Topworld Inftech, India. We are using php-mysql
for our web based projects. I found a problem while i am using the following Query.
SQL-query:
select distinctrow c.name, p.cat_id, p.prd_id, p.name, p.description, p.title, p.price
from categories c inner join(products p left join(products a
left join products b on a.prd_id = b.prd_id)on p.prd_id = a.prd_id)
on c.cat_id = p.cat_id where lower(p.name) like lower('%a%') or
lower(a.title) like lower('%a%') or lower(b.description)
like lower('%a%');
Error
You have an error in your SQL syntax near 'inner join(products p left join(products a
left join products b on a.prd_id = ' at line 2
Can u tell me how to solve this problem. Waiting eagerly for your reply.
With Regards,
V.Satakopan,

Well, that's what's supposed to happen if you have a primary key or unique key on multiple columns where the last column is an AUTO_INCREMENT value. If you want your AUTO_INCREMENT column to have unique values for each row, then you could drop that index and set up a PRIMARY KEY on just the AUTO_INCREMENT column. Actually, I'm not sure I understand what you want to do, so I'm just guessing. If that doesn't answer your question, please clarify. Hi i want to fix the auto_increment col to have unique entries, but if i drop the index there are double entries in for the col, so i dont think it works just by dropping the key. there is data in the table that i dont want to loose. regards sven - 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?

mysql.sock
Hi, I have a problem with MySQL. I am running Redhat Linux 6.1, MySQL 3.23.38 and PHP 4.0. The command line client mysql is working perfectly. But if i try to connect to the MySQL server from a web site using PHP I get this error message: Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111) in /web/domains/allegro-viatatry/index.php on line 3 In the index.php I am using the same code I used on other machine, with the same parameters, and it worked. I looked into the /tmp directory. There is no file named 'mysql.sock'. Please help. Thank you. Marek Mahdal, Slovakia

Respected Sir,
I am working as a System Analyst for Topworld Inftech, India. We are using
php-mysql for our web based projects. I found a problem while i am using the
following Query.
SQL-query:
select distinctrow c.name, p.cat_id, p.prd_id, p.name, p.description, p.title,
p.price
from categories c inner join(products p left join(products a
left join products b on a.prd_id = b.prd_id)on p.prd_id = a.prd_id)
on c.cat_id = p.cat_id where lower(p.name) like lower('%a%') or
lower(a.title) like lower('%a%') or lower(b.description)
like lower('%a%');
Error
You have an error in your SQL syntax near 'inner join(products p left join(products
a left join products b on a.prd_id = ' at line 2
Can u tell me how to solve this problem. Waiting eagerly for your reply.

Veerapuram:
What's the possibility you could set your clock correctly?
We appear to be in the year 2001, although that probably has little to do with
the issue you've reported.
Inner join requires the ON keyword:
from categories c inner join(products p left join(products a
If the above could possibly work, it would have to be:
from categories c inner join on products p left join(products a...
You might have some other issues with your query.
It's typically more useful to capitalize reserved words and Ucase query terms.
Recommendation:
SELECT ThisField, ThatField
FROM ThisTable
ORDER BY SomeArbitraryField;
Less useful:
select thisfield, thatfield
fromt hisfield
order by somearbitraryfield;
Perhaps the difference between the above 2 statements makes it obvious. Or,
perhaps you didn't note the deliberate mistake.
MySQL will honor capitalization in it's error messages.

Problems with Fulltext query
Hi,
I have some problems with the Fulltext query it doesn't
seem to function as I aspect. E.g. I have a table with a
Fulltext index on columns title and description.
If I query for:
SELECT node_id, title FROM node WHERE MATCH (title,description)
AGAINST('bil');
(bil is car in Danish) it doesn't get any results back. It's not because
'bil' is a stop word and it cannot be in more than 1% of the records (I've
tried
to query like this WHERE (title LIKE '%bil%' OR description LIKE '%bil%')
and
came up with a lot of hits but not nearly halve).
Shouldn't a match against a description like this
'Find butikker på nettet indenfor kategorier som tøj, møbler, have, smykker,
hobby og bil m.fl.'
or a title like this 'Bolig, Have Bil'.
Any help is very much appreciated.

java driver
I'm new to mysql and relatively new to java. I've downloaded a type 4 driver from
mm.mysql. I've put the folder containing the driver in my classpath and included the
driver in my code as per the instructions as follows:
try{
Class.forName(org.gjt.mm.mysql.Driver);
}
The problem is that though the code compiles it throws a ClassNotFoundException when I
try to run it. For some reason the driver is not found. I'm probably missing something
really obvious but can anyone help me with this.

Fw: Adding data to Mysql from VB6 front end

I am using VB6 as front end tool. MY problem is: that when i am trying to enter the data from front end to the colunm having Varchar it is taking null value from front end. i had used these command mysqlcreate table table_name (col_1 varchar(25) not null,col_2 int(6)); The table gets created,however, if i am trying to enter the data from front end,in an empty table, my data is not get stored in to the table in case varchar or char but it works for integer or float. On the other hand when I enter the data throuhg the backend directly, then it is taking data in the varcha of char columns. Infact when I enter the first recordset through the backend and the rest of the records through the front end, then it allows it but the column width is restricted to the first entry through the backend in case of varchar and char. Please help on how I can add data from the front end. Thanks and Regards, Manish Poddar

Re: Relationships???
Referential integrity should be maintained by the program (programmer) using the file handler/database. We design all of our schemas with a Parent/Child hierarchy in mind. We always have a unique key and there is always a column or key in common where any relationship exists or could exist between tables. Consider an invoice with a 1-many relationship. Header information regarding the sold to, ship to, etc.. and the Detail containing the items, quantity, etc... . These two tables would have an invoice number field/column in common. The program used to Add,Edit,Delete would enforce the relationship, thereby, maintaining referential integrity. The concept of a DBA (read 'not a programmer') attempting to enforce referential integrity by pure schema design without consideration of the applications designed to use the data or the unlimited creativity of the end-user at the keyboard over simplifies the process and itself imposes data integrity questions.

Check your AUTO_INCREMENT column. You probably have it set to a TINYINT (0-128). Use ALTER TABLE to change it to an INT or BIGINT. I hope this helps.

Stringifying MySQL C types
Hi, does the MySQL client library contain any support for a proper stringification of the MySQL specific data types like my_ulonglong?

RE: Can only create 127 records in a table :o(
Your autoincrement column is of type TINYINT. This type is specifically designed to only hold numbers from 0 to 127. For best results, use an INTEGER - they can accept numbers up to 999 IIRC.

Re: Collapsing queries
Thank you for your help but this is not quite what I wanted. I tried your solution, but it raises the following problem: It would return 1 | Hello World | Foo 1 | Hello World | Bar and if I neglect to look at the msg_id in the first column (which I hope I can get rid of) then there is no way of saying if it's one msg to Foo and Bar, or if it's two messages, one for Foo and one for Bar. So when i said in the subject header collapsing, I really meant it ;-) Do you have more resources? Cheers, Matt --- SELECT * FROM content, address WHERE content.msg_id = address.msg_id If I understand what your asking for, you want a JOIN. If I don't understand, forgive me, it's late... :) Hello, I am relatively new with MySQL (and SQL for that matter) and I couldn't find much reference to my problem in earlier posts. Let's say I have 2 tables, CONTENT: msg_id, msg_text ADDRESS: msg_id, address and I receive the msg Hello World addressed to the twins Foo and Bar. now my tables look like this: CONTENT: 1 Hello World ADDRESS: 1 Foo 1 Bar I am desperatly looking for a sql statement that would produce 1 | Hello World | Foo, Bar Is there such a thing??

Well, that's what's supposed to happen if you have a primary key or unique key on multiple columns where the last column is an AUTO_INCREMENT value. If you want your AUTO_INCREMENT column to have unique values for each row, then you could drop that index and set up a PRIMARY KEY on just the AUTO_INCREMENT column. Actually, I'm not sure I understand what you want to do, so I'm just guessing. If that doesn't answer your question, please clarify. Hi i want to fix the auto_increment col to have unique entries, but if i drop the index there are double entries in for the col, so i dont think it works just by dropping the key. there is data in the table that i dont want to loose. Drop the AUTO_INCREMENT column, than add it back as an AUTO_INCREMENT PRIMARY KEY.

Try to repair it But then myisamchk finds nothing, even using extended-check: angelina:/usr/var/devel# myisamchk -e calls Checking MyISAM file: calls Data records: 457423 Deleted blocks: 0 myisamchk: warning: 1 clients is using or hasn't closed the table properly - check file-size - check key delete-chain - check record delete-chain - check index reference - check data record references index: 1 - check records and index references MyISAM-table 'calls' is usable but should be fixed My suspicion is that this is because I inproperly copied the table from our main database server. The reason I say so is that the above warning seems invalid; SHOW processlist reports no client threads accessing this table. Even so, why would this cause the problem running the DELETE query? And attempting to repair the table with myisamchk gets rid of the above warning but doesn't fix the problem with the query. Any thoughts? Thanks, Kyle Cronan [EMAIL PROTECTED] P.S.

order by rand() question
Hi all, trying to do something and have it be as efficient as possilble. My question is if I have a table with say 10,000 rows in it, and I issue a command like this select * from table where number=1 order by rand() limit 1; If 1000 rows would match this command does mysql first find all 1000 rows and THEN randomly select 1 of those to return, OR does it just randomly start somewhere and then stop when it finds one? The first method would be really slow and inefficient, but I am afraid that is how it works? Is there anyone out there that knows FOR SURE how the order by rand() operation works? I can't find a specification out there for it.

RE: Collapsing queries
this is as close as I could come to what you want.
it involves 2 steps
set a variable
set @var:= '';
then query
select address.msg_id, content.msg_text,
@var:= CONCAT_WS(',',@var,address.address) as addresses
from content, address
where content.msg_id = address.msg_id;
this returns a list but if you grap the last one in the list
it will be what you want
++-+---+
| msg_id | msg_test| addresses |
++-+---+
| 1 | Hello World | Foo |
| 1 | Hello World | Foo,Bar | --- it will always be the last one you
can't reorder
++-+---+
that's as close as I could figure

Subject: Re: Collapsing queries
Thank you for your help but this is not quite what I wanted. I tried
your solution, but it raises the following problem:
It would return
1 | Hello World | Foo
1 | Hello World | Bar
and if I neglect to look at the msg_id in the first column (which I hope I
can get rid of) then there is no way of saying if it's one msg to Foo
and Bar, or if it's two messages, one for Foo and one for Bar.
So when i said in the subject header collapsing, I really meant it ;-)
Do you have more resources?

RE: order by rand() question
I don't think the answer has changed since last week :-)
IMHO it's not really slow and inefficient, anyway - this script:
---start---
?php
$db = mysql_connect(localhost, root, :-));
mysql_select_db(Playground, $db);
mysql_query(CREATE TABLE mytable (myfield INTEGER UNSIGNED, PRIMARY KEY
myfield)));
for ($foo=1; $foo=1; $foo++) {
$s = INSERT INTO mytable SET myfield=. $foo;
mysql_query($s);
}
?
end
produces a table with 1 rows each containing an integer. Then we do:
mysql SELECT * FROM mytable ORDER BY RAND() LIMIT 5;
+-+
| myfield |
+-+
|9935 |
|3221 |
|1530 |
|3889 |
|2133 |
+-+
5 rows in set (0.08 sec)
Right, that's *less than a tenth of a second*, and that's on a crufy old
P200 that also happens to be serving our company Intranet at the same time
as doing this little experiment.
So what's so inefficient? I can't blink in 0.08 seconds, let alone think a
query is running too slowly.
Cheers

Subject: order by rand() question
Hi all, trying to do something and have it be as efficient as possilble. My
question is if I have a table with say 10,000 rows in it, and I issue
a command like this
select * from table where number=1 order by rand() limit 1;
If 1000 rows would match this command does mysql first find all 1000 rows
and THEN randomly select 1 of those to return, OR does it just randomly
start somewhere and then stop when it finds one? The first method would
be really slow and inefficient, but I am afraid that is how it works? Is
there anyone out there that knows FOR SURE how the order by rand() operation
works? I can't find a specification out there for it.

Cannot connect to database
Hi Folks I am having trouble connecting to a MySQL table using the DBI-connect() call from a Perl CGI script. The error message I get is: Can't connect to database: Access denied for user: 'web504@localhost' (Using password: YES) The web504 account and password are defined in the user table for any host but with no privileges. The web504 account is also defined in the db table for any host but with select and delete privileges for the required database. If I check access rights with mysqlaccess everything is OK. I can also manually access the database from the web server by running mysql as web504. If I change the DBI call to use the root account and password the CGI script runs succesfully.

transactions and pconnect (PHP)
Hi!

Peter Few time ago I had to stop using lock tables as this lead to Peter locked system then somehow the php script was aborted before unlock Peter tables. Peter With transactions we could have the same bad situation if it's not Peter handeled, it's even worse as the result is unexpected depending on Peter the following statements transaction can be committed or rolled back. Peter I'm speaking about the following problem: Peter I issue the begin statement and some of the statements, then PHP Peter script is aborted before the transaction is committed, but as Peter connection is not terminated mysql does not rolls it back. The next Peter statements come from the other PHP script so they could commit Peter transaction or roll it back. The above problem should exist with all transactional databases. Peter The question is - does this problem present or not ? If it does I Peter think it would be nice to modify the behavior so PHP would unlock Peter all the tables and rollback all the transactions from the previous Peter script. I think that if a PHP script is aborted and you are using persistent connections, then it should send a 'bk abort' to the database if there is an active transaction. I don't however think the current PHP code does this. Peter and Tim, could you try to sort this out? This is a question for the PHP list..

Sure, it may be that fast when you're selecting one row out of 10,000 ints on a lightly loaded server. However MySQL works this way: - SELECT * FROM mytable; - Order all found rows by rand() - Send back the first 5 It's not that inefficient when you just have one column, since that's all you'll be getting anyways, however I have a table with 38 columns, 141000 rows and lots of data you are making MySQL get a lot of data it doesn't end up using. This is how fast your fast query runs on it (granted this is on a server with medium to heavy load and ~50 queries per second): mysql select * from users order by rand() limit 1; ... 1 row in set (1 min 29.48 sec) You can make this a little faster: mysql select id from users order by rand() limit 1; ... 1 row in set (10.10 sec) mysql select * from users where id = 123456; ... 1 row in set (0.12 sec) But it's still quite inefficient. The best way would be to generate the random numbers from your application. If you wanted five rows, generate 10 numbers (just to be really safe in case a few reference deleted rows) between 1 and max(id) (assuming you have an auto_increment column named id) and do: mysql select max(id) from users; ... 1 row in set (0.12 sec) mysql select * from users where id in (1, 2, 3, 4, 5, 6, 7, 8, 9, 10) limit 5; ... 5 rows in set (0.33 sec) - 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?

Look up myisampack in the mysql manual at http://www.mysql.com/doc/. The only drawback is you can't modify the table. I have a table that has massive amounts of text. Just plain text, stuff that would compress REALLY well. Does mysql have any sort of compression internally for the table data that it stores?

Re: mysql died with innodb
Dan, of course InnoDB could catch the error and send the error message to the client. But the problem is that we have to get NFS to flush the files, otherwise we may very easily get database corruption in case of a crash. MyISAM does not call f(data)sync at all, but then you may have to run repair if it crashes. I looked at FreeBSD manuals at www.freebsd.org and did not find any notice that fdatasync would not work for NFS. Presumably with some settings it should work, or maybe there is a bug in the OS/hardware combination.

Re: mysql died with innodb
In the last episode (Jun 15), Heikki Tuuri said: of course InnoDB could catch the error and send the error message to the client. But the problem is that we have to get NFS to flush the files, otherwise we may very easily get database corruption in case of a crash. MyISAM does not call f(data)sync at all, but then you may have to run repair if it crashes. I looked at FreeBSD manuals at www.freebsd.org and did not find any notice that fdatasync would not work for NFS. Presumably with some settings it should work, or maybe there is a bug in the OS/hardware combination. fsync (FreeBSD doesn't have fdatasync) definitely does work with NFS. Knowing the errno that fsync() returned when it failed might help the debugging process, though. -- Dan Nelson [EMAIL PROTECTED] - 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?

properly checking for existing records with perl
I am writing a small perl script that will write data to a Mysql
database. The SQL will need to be different based on whether or not the
e-mail address already exists in the database though. I coded something
that works, but I would like some feedback as to whether or not this is
the best way. I need this to be as efficient as possible because there
is occasionally very heavy traffic on it, and there will be over 100,000
records in the database.
Basically, I collect the data, then I query the database to see if the
e-mail exists. and if it returns row(s) then I update the data to the
database. if it doesn't, i insert the new data into the db. any help
is appreciated! here's the code snippet:
# see if the e-mail exists
$query = SELECT email FROM $table where email = \'$email\';
$dbh =
DBI-connect(DBI:mysql:database=$database;host=$host,$user,$mysqlpa
ssword,{'RaiseError'=1});
$sth = $dbh-prepare($query);
$sth-execute();
$numrows = $sth-rows;
# if there are rows returned, the e-mail is in there, so we need to
update the record
if ($numrows ge '1') {
# set the SQL for UPDATE
$sql = UPDATE $table SET prefix=\$prefix\, firstname=\$firstname\,
middlename=\$middlename\, lastname=\$lastname\,
address1=\$address1\, address2=\$address2\, city=\$city\,
state=\$state\, zip=\$zip\, country=\$country\, email=\$email\
WHERE email = \$email\;
#actually execute the UPDATE
$sth = $dbh-prepare($sql);
$sth-execute();
# finish and disconnect
$sth-finish();
$dbh-disconnect();
}
# if there are no rows returned, it's a new record, so insert it
else {
## Set sql to perfect insert format
$sql = insert into $table
(prefix,firstname,middlename,lastname,address1,address2,city,state,zip,c
ountry,email,phone,howfound,interest,lastpurch_web,optin,optin_partners,
mail_type,comments,record_type,date,browser) VALUES
(\$prefix\,\$firstname\,\$middlename\,\$lastname\,\$address1\,
\$address2\,\$city\,\$state\,\$zip\,\$country\,\$email\);
#actually execute the insert
$sth = $dbh-prepare($sql);
$sth-execute();
# finish and disconnect
$sth-finish();
$dbh-disconnect();
}

Re: mysqldump on large database..
Hello I created a perl script that might help. Because I like to have a full backup of my databases and table backups (I know I can split the full backup, but I'm too lazy ;), I created a perl script that queries MySQL for the table names in the database and then creates a shell script with individual mysqldump commands for each table, after it creates the script it executes it. I think this will help in this case because it is only asking MySQL to dump one table at a time. With 10,000 tables the script will run for a long time, but at least it will be automated. Contact me off the list and I will be glad to send it to you. Have a great day... John Someone please correct me if my idea of how mysqldump runs (i.e. it will still attempt to open all files) is incorrect.

Which OS are you running? You should be able to open 2 files (index+data) on most Unixes with a little tuning. It may be slow, but it should work. Alternatively, you can temporarily move tables 1000 at a time into another directory, mysqldump them, and move them back. - 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?

Expected speed of MySQL on a 166
I'm currently using a 166 UNIX machine for a dedicated MySQL database, and I'm interested in knowing what kind of speed I should be expecting from it. I ask because right now it's at a point of being unusable even for development on some of the larger queries. I compiled MySQL 3.23.37 myself with -O6's -march-i586 and various ./configure options I don't remeber. The database I'm using has 3 tables of about 9 thousand entries, un-indexed decimal(5,8)'s, and a few tinytext's. There are 168 columns. A query like 'SELECT 97TotalAssets, 98TotalAssets FROM Business WHERE SIC='112'' will take a good 5 seconds. Any more useful of a query will take up to 90 seconds. All the queries are SELECT's. Is there something I can do, or am I going to need something faster than a 166?
