Re: store JPG in MySQL DB
For real-life example, check out http://cdbaza.ultracgis.com, and check out the filename of the thumbnails images. I'm SELECTing those images from the MySQL database. That's how it's done: 1_ Create a table to store your JPGs, and the column that holds JPG data should be declared as BLOB CREATE TABLE images ( image_id INT UNSIGNED NOT NULL AUT_INCREMENT PRIMARY KEY, image BLOB NOT NULL ); 2_ Now you are ready to load the JPG data into the image column. I use Perl to open the JPG file and dump the contents into the table, and the resulting query looks something like: INSERT INTO images SET image=here goes contents of the JPG file; Perl code that does this job would look like: local ($/); sysopen (JPG, test.jpg, O_RDONLY) or die $!; $dbh-do(qq|INSERT INTO images SET image=?|, undef, JPG); close (JPG); Sorry if you don't know Perl, but you should be able to do similar thing in any other language you might be using Good luck! -- Sherzod - 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?

MyISAM internal algorithms
Hi MySQL-Team, my question is about MySQL(which means MyISAM) internal sorting/storeing algorithms. I found some hints in the manual (How MySQL ... e.g. store tables), but not exactly what I want. I don't need any exact information or code fragments (I fell down my chair when I took a first look to the source), it's just a point of my interest how MySQL manages datasets. One of my professionals told me that it would have something to do with B-(2-3-4)-Trees that are the best solution for reading blocks from disks, and that indexes would be stored in Binary-sorted-Trees or Tries. Do you have any short description of this for me?

Join takes way too long. How to optimize this smal query?

optimisation trouble
Hi! I got a problem I'm trying to fix with no luck. I got 2 tables : CREATE TABLE news ( id int(6) NOT NULL auto_increment, topic_id int(3) NOT NULL, section_id int(3) NOT NULL, author_id int(6) NOT NULL, lang_id int(2) NOT NULL, user_id int(6) DEFAULT '0' NOT NULL, state int(1) DEFAULT '0' NOT NULL, main_page int(1) DEFAULT '0' NOT NULL, timestamp timestamp(14), title varchar(150) DEFAULT '' NOT NULL, departement tinytext, ip varchar(9) NOT NULL, KEY id (id,topic_id,section_id,author_id) ); CREATE TABLE news_body ( id int(6) NOT NULL auto_increment, body blob NOT NULL, content_type varchar(16) DEFAULT 'text/plain' NOT NULL, KEY id (id) ); (and few more but it doesn't matter). A select gives me : desc SELECT news.id,news.timestamp,news.title,news.departement,news.author_id,news_body.body,news_body.content_type,topics.topic,sections.section,news_author.name,news_author.contact FROM news_body,news,topics,sections,news_author WHERE news.id=news_body.id AND news.author_id=news_author.id AND news.topic_id=topics.id AND news.section_id=sections.id AND news.state='1' AND news.main_page='1' order by news.timestamp desc LIMIT 10; +-++---+-+-+-+--+-+ | table | type | possible_keys | key | key_len | ref | rows | |Extra | +-++---+-+-+-+--+-+ | news_body | ALL| PRIMARY | NULL|NULL | NULL| 7853 | |Using temporary; Using filesort | | news| eq_ref | PRIMARY | PRIMARY | 4 | news_body.id|1 | |where used | | topics | eq_ref | PRIMARY | PRIMARY | 4 | news.topic_id |1 | | | | sections| eq_ref | PRIMARY | PRIMARY | 4 | news.section_id |1 | | | | news_author | eq_ref | PRIMARY | PRIMARY | 4 | news.author_id |1 | | | +-++---+-+-+-+--+-+ and it takes about 1.5sec to run.

I did read the mysql documentation, but I don't see how to fix that. Would it be better to put the body into the news table ?

Re: Storing UTF-8 text with MM.MySQL 2.0.13 driver.
This code works fine, which shows you can use the useUnicode and
characterEncoding properties with simple Statement's:
Properties prop = new Properties();
Class.forName(org.gjt.mm.mysql.Driver);
// true as String and not: Boolean.valueOf(true)!
prop.put(useUnicode, true);
prop.put(characterEncoding, UTF-8);
con = DriverManager.getConnection(dbUrl, prop);
String s = \u20AC (euro) \u2126 (ohm);
Statement stm = con.createStatement();
stm.executeUpdate(DROP TABLE IF EXISTS TestUnicode);
stm.executeUpdate(CREATE TABLE TestUnicode (code VARCHAR(128)));
stm.executeUpdate(INSERT INTO TestUnicode (code) VALUES (\'+s+\'));
ResultSet rs = stm.executeQuery(SELECT code FROM TestUnicode);
if (!rs.next()) {
System.err.println(No row?!);
} else {
System.out.println(s.equals(rs.getString(code)) ? OK : FAILED);
}
...
The downside is that the stored String does NOT appear correct in the
SQL tools (for instance MySqlManager). I *think* the problem is that
MySQL is not using UNICODE.
Is there a workaround for this issue??

SQL join help
Dear list, I've done basic SQL for a number of years, but I recently came up against a query I can't quite seem to figure out the join syntax for. Suppose I have rows in an Object table which are linked in a hierarchy by the entries in a Link table and I want to find all Objects which have given set of Objects as children. For example, given the following data ... CREATE TABLE Object ( id int(11) NOT NULL auto_increment, PRIMARY KEY (id) ); INSERT INTO Object (id) VALUES (1); INSERT INTO Object (id) VALUES (2); INSERT INTO Object (id) VALUES (3); INSERT INTO Object (id) VALUES (4); INSERT INTO Object (id) VALUES (5); INSERT INTO Object (id) VALUES (6); CREATE TABLE Link ( parent int(11) NOT NULL, child int(11) NOT NULL, ); INSERT INTO Link (parent, child) VALUES (1, 4); INSERT INTO Link (parent, child) VALUES (1, 5); INSERT INTO Link (parent, child) VALUES (2, 4); INSERT INTO Link (parent, child) VALUES (2, 5); INSERT INTO Link (parent, child) VALUES (2, 6); INSERT INTO Link (parent, child) VALUES (3, 4); ... I want to find all Objects that have exactly 2 children with ids 4 and 5 (i.e. should match 1, but not 2 or 3) ... what's the query syntax? How about if I want to find all Objects which have no children (i.e. should match 4, 5 and 6, but not 1, 2 or 3).

Is this a Bug?: Query returns an unexpected result.
Description:
Query returns an unexpected result.
How-To-Repeat:
run the script below:
-
create table member
(
userid int(11) primary key auto_increment,
mailaddress char(40) not null
);
insert into member values (null,'[EMAIL PROTECTED]');
insert into member values (null,'[EMAIL PROTECTED]');
create table orders
(
orderid int(11) primary key auto_increment,
userid int(11) not null,
placedate datetime,
status enum('WORKING','ACCEPTED','CANCELED','SHIPPED'),
comments char(255)
);
insert into orders values (null,1,sysdate(),'ACCEPTED',null);
insert into orders values (null,2,sysdate(),'ACCEPTED',null);
alter table orders add
(
contact_date datetime,
payment_date datetime,
shipping_date datetime,
followup_date datetime,
cancel_date datetime
);
update orders set shipping_date=sysdate();
update orders set cancel_date=sysdate() where orderid=1;
select
o.orderid,
o.shipping_date,
o.cancel_date
from orders o, member u
where o.userid = u.userid;
select
o.orderid,
o.shipping_date,
o.cancel_date
from orders o, member u
where o.userid = u.userid
and o.orderid = 1;
-
the results of the last two queries are:
orderid shipping_date cancel_date
1 2002-05-20 21:50:24 NULL
2 2002-05-20 21:50:24 NULL
orderid shipping_date cancel_date
1 2002-05-20 21:50:24 2002-05-20 21:50:24
in the first query, cancel_date should not be null for orderid=1.

Re: Join takes way too long. Query optimizing, or denormalizing?
I guess this is not an issue on the index. Explain select says it is using the index. So I assume, that I did just write down the join syntax wrong. MySQL is joining all 32000 records with the city table and then looks for the country code. So this looks ok to me. Maybe I should denormalize my data and include the country code in the other table as well?

Re: Problem with join syntax
* andy [EMAIL PROTECTED] thank you roger for your reply. I am wondering how to form the stmt if I do already know the user_id I tryed this, but it does not work though. Anyhow there has to be a from field. But on which table? SELECT w.website, c.comment LEFT JOIN user_websites AS w ON w.user_id = '10' LEFT JOIN user_comments AS c ON c.user_id = '10' That is correct, when you use LEFT JOIN (or any join, actually) you must select FROM one table, and then JOIN with the other table(s). Try this: SELECT w.website, c.comment FROM user_websites AS w LEFT JOIN user_comments AS c ON c.user_id = w.user_id WHERE w.user_id = '10' Note that the ON expression contains one field from each of the two tables. This expression is also known as the 'join condition'. It is perfectly legal to use a constant, like you did, but that will not be possible in most cases, like if you want to list more than one user. The above statement will list the website for the user with id '10', even if he does not have an associated comment, because of the LEFT JOIN. The following statement would only find website-rows _with_ comments, ie, if user_id '10' does not have a comment, you will get 0 rows: SELECT w.website, c.comment FROM user_websites AS w, user_comments AS c WHERE c.user_id = w.user_id AND w.user_id = '10' This statement does not contain the word JOIN, but it is still a joined select. The comma between the tables in the FROM caluse means 'INNER JOIN'. This is the _excact_ same statement: SELECT w.website, c.comment FROM user_websites AS w INNER JOIN user_comments AS c WHERE c.user_id = w.user_id AND w.user_id = '10' ...and this is also legal (in versions 3.23.16 and later): SELECT w.website, c.comment FROM user_websites AS w INNER JOIN user_comments AS c ON c.user_id = w.user_id WHERE w.user_id = '10' The join condition can be in the WHERE clause, but it is still a join condition. I hope this makes things clearer. :) -- Roger sql - 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?

I don't need any exact information or code fragments (I fell down my chair when I took a first look to the source), it's just a point of my interest how MySQL manages datasets.

Re: store JPG in MySQL DB
well, let's just say if it crashes it will mean longer recovery time, you are adding extra processing to the SQL server to handle data it wasn't meant to handle, storing it in the file system has the main advantage that if any changes occurs you can change it faster + easier, besides a database is supposed to store essential data so you don't overload it with things that can be calculated or made pretty easily, and I'd say an image fits under that category.

Re: Join takes way too long. Query optimizing, or denormalizing?
In my experience, you rarely want to fully normalize your data (unless it's something simple). City and country codes I wouldn't split up because they never change. Well, alright, there have been quite a few new countries popup in Europe recently. But you don't need to change hundreds or thousands of records, in this case, to update your data, so full normalization doesn't buy you anything. I like to think of the joke where the guy programmed 911 (US emergency phone number) on his speed dial, so to dial 911 he just had to press *78. I guess this is not an issue on the index. Explain select says it is using the index. So I assume, that I did just write down the join syntax wrong. MySQL is joining all 32000 records with the city table and then looks for the country code. So this looks ok to me. Maybe I should denormalize my data and include the country code in the other table as well?

Hello everyone. While you are on this subject, can I ask you a question? Is it possible to store sound, or video in the mySQL database? If so, is it wise? Are there any performance issues I should be aware of I just want my users to be able to add their photo, and sound (or maybe a short video) to their profile.

Re: query - primary key
Hi, Firstly, how do i correct that error of BAD text coz i actually have a text file which has a HISTORY dump from IE. Secondly what about the Duplicate Entry stuff, its comming for all the URLs why?? Regards Sameer It's been my experience with loading data from text files that most errors are caused by the end-of-line character/s. You may be importing text from a file created by Windoze, and loading it into a db on Unix. The end of line characters are different. In this case you will have to specify what the 'termination' is: \r\n, \n, or whatever. Also check your field delimter: is it a tab or what. If it's a tab you shouldn't have to do anything, but if it's something else you will either have to change your textfile, or specify what the field terminator is. Something like this: LOAD DATA LOCAL INFILE yourfile.txt INTO TABLE LevelOne FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\r\n' This mixup will cause the duplicate key error as well I believe, since the line pointer is not moving forward in your file. -- /* All outgoing email scanned by Norton Antivirus 2002 */ Amer Neely, Softouch Information Services W: www.softouch.on.ca E: [EMAIL PROTECTED] V: 519.438.5887 Perl | PHP | MySQL | CGI programming for shopping carts, data entry forms.

Patch for mysql_read_default_options segfault

Re: Help me to Frame Query
I would structure things differently. Have you thought about making each question a record/row in a table? Then if you add or remove a question, you don't have to change you table structure or your code if you do it right. You could also then easily compile stats on a per question basis. Like how many people answer 4 for question #25 or how many people got the right/wrong answer. It's a little harder to program, but it would be the most flexible. hi all, i am working on Mysql to make a table to store following data Varchar Semester, Varchar Name, Varcahr Course, int Enroll, int Responses, int Question#22, int Question#23, int Question#24, int Question#25, int Question#26, int Question#27, int Question#28, int Question#29, int Average One Sample Data row is XYZ, 1999,ABCDEF,990,6,4,4.75,3.33,4.67,4.00,4.25,4.00,4.25,4.50,4.22 My question is, can i store the data for fields Question#22.Question#29 in one data field in table (Say TABLE1), and when i retrieve the field, i should be able to break them into individual questions#, take each Question# into PHP variables and work on it. Any idea how to do that? My aim is to reduce the number of columns for the TABLE1.

Need some direction please
Here's my dilema. Our website runs a quarterly prize giveaway. Currently we have an ASP form that gathers the inputed info into a database and then sends us an e-mail confirmation of the entry. Our rules specifically state that only one entry is allowed per quarter. As I am not a programmer (just a dabbler in programming) I have no idea on how to do the following and need some help. What we need is a script that will check our current database against an e-mail, last name, and first name entry. If that entry is in our database a message pops up telling them that they have already registered with us. If there entry is not located in our database then the new info passes along unhindered. We are on a Cobalt RaQ4r with ChiliAsp 3.62 installed and are using MySQL. Thanks in advance for the help. Sincerely, Stephen M.

Hung login mysql processes - unable to kill.
Hi everyone, I have a rather obscure problem with hung login connections in mysql. I've set the wait|interactive_timeout to 120 seconds, but it has no effect.\ If I attempt to `mysqladmin kill id`, the process is marked 'killed', but never goes away. Now I know the main problem is with the program I am using to create the connections and access the data, but I'm ignoring that right now because I want to deal with these stale (or hung) login processes. And find out how to remove them or time them out (without restarting mysql mind you, if at all possible). Here's some brief output from my `mysqladmin processlist`: ++--+---+--+-+--+---+--+ | Id | User | Host | db | Command | Time | State | Info | ++--+---+--+-+--+---+--+ | 22088 | via_httplogs | localhost | | Connect | | login | | | 22877 | via_httplogs | localhost | | Connect | | login | | | 23135 | via_httplogs | localhost | | Connect | | login | | | 23226 | via_httplogs | localhost | | Connect | | login | | | 26523 | via_httplogs | localhost | | Connect | | login | | | 32105 | via_httplogs | localhost | | Connect | | login | | | 32113 | via_httplogs | localhost | | Connect | | login | | | 37098 | via_httplogs | localhost | | Connect | | login | | | 38300 | via_httplogs | localhost | | Connect | | login | | | 51212 | via_httplogs | localhost | | Connect | | login | | | 89713 | via_httplogs | localhost | | Connect | | login | | | 99008 | via_httplogs | localhost | | Connect | | login | | | 119642 | via_httplogs | localhost | via_httplogs | Sleep | 2 | | | | 119644 | via_httplogs | localhost | via_httplogs | Sleep | 29 | | | | 119645 | via_httplogs | localhost | via_httplogs | Sleep | 14 | | | | 119646 | via_httplogs | localhost | via_httplogs | Sleep | 41 | | | ... Nothing shows up in the mysql error log either. Any ideas?
