Re: Binary data
Barry,
This can be done using normal insert/update statements. You only have to
'escape' the binary zero, the backslash and the quotes (' or ") out;
suppose jpg contains the binary data, the following code will do the trick:
(pseudo code:)
for (i=length(jpg); i--; i0) {
if (jpg[i] in [#0, '\', , '"'] ) { jpg=jpg[1..i-1] + '\' +
jpg[i..length(jpg)]
};

It's real. Here is a demonstration. First, the table definition...
Auto_increment fields will re-use values for ISAM tables (i.e.
tables created in versions before 3.23 or being created with
TYPE=ISAM). This behaviour was changes with the introduction
of MyISAM tables (introduced in v. 3.23).

Re: Backup?
While on the subject of backup scripts - Someone had asked on a message board for my webhost about whether a script existed for backing up a MySQL database, and, rotating backups. I couldn't find anything that did everything that he asked, so I wrote something myself. It's written in Perl and uses mysqldump since the person didn't have a shell account, much less root, on the MySQL server. It's not the greatest example of Perl programming, and it's only written to backup a single database, but hey, I didn't spend more than 2 hours on it. I've used it myself on some of my databases for the past 5 months with no problems. I just never got around to tweaking it... I have to get out of the habit of treating these sorts of things as trivial. Here is the script - http://www.trickortreat.org/mysql_backup.txt Basic usage - create a directory for the database backups, edit some variables in the script and create a cron job. And here is an example of a crontab file for using the script - http://www.trickortreat.org/mysql_backup_cron.txt Mike Willey [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?

Choice of BLOB or store in a directory
I would much appreciate to hear from experienced mySQL practitioners on the following: I have a large relation in mind (strictly fixed length for performance) with potentially 1-3 million entries. Associated with each of these rows i have a variable number of blobs. I would not consider storing them in the table itself for obvious performance and other reasons but i have choices and i would like all your opinions on them : A) Would you store them in a single relation? B) Because of max table size would you consider one table for each possible kind of blob? C) Consider storing them as files in directories? D) If recommending (A/B) which table type is recommended? In particular has anyone experience on the choice between (B) (C) on performance grounds? e.g. how does directory search compare to an index in mySQL?

RE: AND on a many to many table, with arbitrary ANDs
I don't think that solves his problem, since he wants to know AND, not
OR...
the closest thing I could get to was using select into... although it
seems like it might be possible with a left join, i just can't figure
out how.
one of the things that I thought of with select into was to select count
and the story name from the story,category, and storycategories join on
their respective ids, then used IN ('Classics','Childrens') and grouped
by story, yielding something like:
Peter Pan | 2
Alice in Wonderland | 2
Pokemon | 1
War and Peace | 1
Tale of Two Cities | 1
then selecting from that subset for count = 2;
if anyone can think of a way to do it with left joins, or a way to do it
without select into, i'd be very curious to see the solution :0

Subject: AND on a many to many table, with arbitrary ANDs
Hello everyone,
I am in the process of building a search engine on a database. I have
two
tables that have a many-to-many relationship: A story table and a
category
table.
Story Table:
---
id | story|
---
1 | Alice in Wonderland
2 | Peter Pan
3 | Pokemon's adventure
4 | Tale of Two cities
5 | War and Peace
..etc..
Category Table:
--
id | category|
--
1 | Children
2 | Classics
3 | Tolstoy
..etc..
`
Storycategories Table:
--
storyid | catid |
-
1 | 1
1 | 2
2 | 1
2 | 2
3 | 1
4 | 2
5 | 2
5 | 3
..etc..
From my (admittedly dim) understanding of SQL, this is how one is
supposed
to organize a many-to-many relationship. So peter pan is listed as 1
(childrens) and 2 (classics).
I am writing a web interface to do searches for stories. In my web
interface, you have something like this:
---
[]Classics []Childrens []Tolstoy []Fiction ...
Search Categories:
(x) match all categories
( ) match any category
---
In order to build a query that matches ALL categories, I use aliasing.
To
do
a search on stories that are Children AND Classics, I make two
instances
of
each table as shown in the example below.
select
S.story
from
stories_tbl S,
categories_tbl C1, storycategories_tbl O1,
categories_tbl C2, storycategories_tbl O2
where
S.id = O1.storyid and O1.catid = C1.id and
C1.category like "Children" and
S.id = O2.storyid and O2.catid = C2.id and
C2.category like "Classic"
group by
story
This query works fine. My problem arises when I have many categories
to
choose from. If I check many of the categories boxes, and select match
all
categories, my program builds a query with a large amount of tables, I
get
an error like this:
Error 1116: Too many tables. MySQL can only use 32 tables in a join
My guess is that there is a limit of 32 tables in a join, and that my
use
of
aliasing here ends up violating the 32 table limit.
Even worse is when I make a query that has a little less than 32
tables.
This won't give an error, but will leave a process running on the
machine
that consumes 100% cpu. After a while, this process will render the
database
unusable, and no one can use the database until the process is killed!
So to clarify, the query that ends up being built looks like this:
select
S.story
from
stories_tbl S,
categories_tbl C1, storycategories_tbl O1,
categories_tbl C2, storycategories_tbl O2
categories_tbl Cn, storycategories_tbl On
where
S.id = O1.storyid and O1.catid = C1.id and
C1.category like "Children" and
S.id = O2.storyid and O2.catid = C2.id and
C2.category like "Classic"
...
S.id = On.storyid and On.catid = Cn.id and
Cn.category like ""
group by
story
This query fails when "n" is around 16.
My question is, how can I build a query that will support an arbitrary
number of ANDs on a many to many relationship? I'd like to be able to
do a
search on stories that are "Children AND Classics AND Tolstoy AND
Category N" where N is fairly large (hundred or so)..
Is there any way to do this? Am I using aliasing incorrectly?
Those of you that have made it in reading this far, thank you :). I

RE: Finding the 'field names'
hi Jamie I' not too sure about the fields for the tables but I think a better way to implement this is to seperate the items from the options hence you have three tables instead of one,ie table 1 *product_id, (other product fields) table 2 *option_id, name, value, ...(whatever you need) table 3 *+product_id, *+option_id Explanation: Table 1 is used to hold data about the product, ie data that is relevant to the product only. table 2 is used to keep track of the various options that you require. Table 3 will be used to link the product to an option. This way you can alter your options,add or delete, without changing your tables all the time, remember to to try and keep only unique data in a table otherwise you end up duplicating things. Also maintenance becomes a pain(my opinion) regards Barry -Original Message- From: Jamie [mailto:[EMAIL PROTECTED]] Sent: 31 January 2001 02:25 To: Mysql@Lists. Mysql. Com Subject: Finding the 'field names' I was wondering what the SQL command is to find the filed names of a database once it has been created. I'm trrying to write a script that will allow 'options' table to be created where there is an ID fiield for the product then fields representing each of the avalible options eg red blue green which are going to be a boolean variable. I'm hopeing that this is the best way tyo do this as each product can have multiple options and there may even be more option fields added at a later date (which is why I need to be able to find them) My table design: ___ | Product_ID | Red | Blue | Green | Yellow | A4 | A5 | |--||-|--|---|--|--| |_12345678_|__+__|_|__+__|__+___||| |_75487345_|_|__+__|___+_|__|_+__|__+_| |_43657322_|_|_|_|__||| |_12355578_|__+__|_|__+__|__+___||| |_66635678_|_|__+__|__+__|__+___|_+__|| - 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?

You have to eiether change the source or create /etc/my.cnf where you
would define socket file in the [client] options header, as described

Selecting games which a given user can join
Hi there! I'm new to SQL and I can't figure out a query which would give me the result I need. What I want to do is this: I have table that stores names of players and number of the game they play (one player can play more games concurrently). Other users can join the game. For given user I want to display the games which he can join. The only condition is that the user can't join any game which he already plays. If I have this +-+-+ | gid | user| +-+-+ | 1 | jack| | 1 | john| | 1 | peter | | 1 | richard | | 2 | john| | 2 | richard | | 3 | peter | | 4 | jack| | 4 | peter | | 5 | peter | | 5 | john| +-+-+ then for jack I want numbers 2, 3, 5 but not 4; for peter it should be 2 and no other.

Re: How to select the 10 last items from a table?
I think the only way to do it is first get the amount of items:
SELECT COUNT(*) FROM item;
if you use PHP, store the count in a variable called $count.
subtract 10 from count:
$limit = 10;
if($count $limit) {
$limit = $count;
}
$count = $count - 10;
if($count 0) {
$count = 0;
}
then do the following:
SELECT * FROM item ORDER BY id LIMIT $count,$limit;

Re: mysql_fetch_row blocks my computer...
That syntax seems correct. Make sure you have defined Row as:
MYSQL_ROW Row;
Yes this is a structure, not a pointer.
and that result is defined as
MYSQL_RES *result;
Yes it is a pointer.
printf("\n\t%u %4s",j,Row); ---YOUR problem seems to be here! change
Row to Row[0] and see if that works!
This is sure, this line is wrong and must be Row[#], but the programs
does not reach to
this line, it hangs before in the "mysql_fetch_row(result)" line...
I have updated to the latest mysql and recompiled it, and now works ok,
so there was a bug
in compilation of the old mysql or a bug of the library...
Thanks for your help.

Excel-MySQL
Not sure if this was ever asked, but I'm fighting a dilemma over here and the answer to this greatly affects what I'll end up doing: I know I can PULL FROM an MySQL database (sitting on a Limix box) INTO MS Excel.

can I select from one table only where some records exist in anothertable?
Sorry, that's not a very good formulation of the question. I have 2 tables, and I want to retrieve data from records in table A only if there are corresponding records in B. I don't care what's in the records in table B: all I want to know is which items in A _have_ records in B. If I do: select distinct A.this, A.that from A, B where A.key=B.key order by A.key then the join produces zillions of records and the query takes ages. Similarly if I do select distinct A.this, A.that from A left join B on A.key=B.key where B.key is not null it takes ages. I guess if I could somehow apply 'limit 1' to the join, so that I just get any one record from B (I don't care which record: after all I'm not using data from B) then it would go like greased lightning, but I can't see how to express that in mySQL SQL. Is this one of those things that can't be done without sub-selects? Something like: select A.this A.that from A where (select count(*) from B where B.key=A.key)0 (I'm not sure if that's valid SQL, but I hope it conveys my meaning.) regards, -- John Stumbles [EMAIL PROTECTED] I.T.

Re: Are all SQL-databases based on the same query-language?
SQL itself is not the way the data is stored. SQL stands for Structured Query Language and is a way of retrieving and modifying/adding records. If you write your SQL carefuly, yes you can use it pretty much "as is" on any SQL system. There are little changes and such however that every SQL server makes to the ASNI SQL standards. Somethings will work on one, but not another. Just be careful when writing your syntax and you should be fine. - Original Message - From: "SED" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, January 31, 2001 10:26 AM Subject: Are all SQL-databases based on the same query-language?

RE: Are all SQL-databases based on the same query-language?
SQL is a language that is based on standards that are modified every so often. So, yes, in general there are SQL statements that you put together will work with Access, MSSQL, Informix, DB2, and Oracle, etc. But *THE* key issue is that each DBMS application has it's own hooks that are native the vendor's implementation. MySQL's version of SQL doesn't support sub-selects as of yet, for now, but Oracle and SQL Server do. On the flip side, mySQL's version of SQL has better regular expression support than SQL Server. Access' version of SQL is a little bizarre because it requires you to use * instead of % in LIKE clauses, (unless M$ has changed it). I think it's somewhat polluted. Aside from minor adjustments for db connections, you're in decent shape. -Original Message- From: Eric Fitzgerald [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 31, 2001 10:40 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Are all SQL-databases based on the same query-language?

Replication Problem - Bug with master.info?
Description: Replication problem. When I restart my slave server, it is unable to connect to the master. It says it cannot find the log file on the server. I noticed that it looks like the log file it's looking for looks correct but it has has a Line-Feed included in it. I tried fixing the master.info file to remove the line-feed, but it keeps putting it back in there. The only fix I found was to run this SQL command on the slave: CHANGE MASTER TO MASTER_LOG_FILE='server-bin.001'; After running that it works fine, until I restart mysql on the slave again. How-To-Repeat: Set up two master-slave servers and restart mysql on the slave. Fix: Temporary fix: run the SQL command listed above.

To thread or not to thread this is the question ..........
Hi, I have a problem with mysql 3.23.30 (binary distribution) and Slackware 7. Runnining different programs that access to database, the numbers of mysqld grow up. But when a single program exit, the number of mysqld processes should decrease by one. This works on RedHat 7.0 with the same mySQL distribution, but on Slackware 7 the number of mysqld never goes down, and they keep the maximum memory used in the last big query. So I tried to compile the last source distribution 3.23.32 on Slackware 7, but I got the same thing. I know that the mysqld should be threads not processes, and the memory used should be shared with all running mysqld, but something does not work properly. Do you think that the version of libpthread-0.8.so on Slackware 7 could be the cause ? (RedHat 7.0 has the libpthread-0.9.so). I cannot upgrade the OS now, and I think that is not a nice idea moving on the fly libpthread-0.9.so from RedHat to Slackware (the system is up and there are 102 users connected !!!). Could someone help me ? Thanks in advance. marcello - marcello giovagnoli Logical System s.r.l.

Re: Once again ... row to column conversion
Yeah, you should really change the way the database is setup but you could also do something like this. Have perl return an array and just do a foreach on the array and that will give you all the values of each column on the row, without you knowing how many rows there are. Even if your not using perl you can still do it in other languages. On 31 Jan 2001 12:10:36 -0800, Eric Fitzgerald wrote: Change the way it's stored in the table. Seriously, if the data is stored in a single row, there is no way via SQL (not defined in standards, not available in any SQL server implementation I've seen either), then the program has to convert that into columns. The standard mysql utility is capable of doing this, and you can do it in your program. If you want to use the mysql CLI, do something like this: mysql --execute='SELECT fields FROM table WHERE condition' --vertical dbname Otherwise write your program to do it. - Original Message - From: "leo.putz" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, January 31, 2001 11:50 AM Subject: Once again ... row to column conversion Sorry for having to post the same problem a second time - but by now I'm really at a loss.

Queries upon queries
We're looking at moving a web-based application currently built with Microsoft Access and Cold Fusion to a real database platform. I've only just started poking around mySQL, so I'm not really up on its capabilities. One of the things this application relies on fairly heavily is stored queries (aka stored procedures and/or views, depending on what platform you're coming from). There are sometimes five or six layers of SQL, with one query using other queries for their data, between the tables and what the user eventually sees. Poking around the documentation, it appears that mySQL doesn't support that sort of thing. Do I have that right, or am I missing something important? Even if I can't get deeply layered queries with mySQL, is there a relatively painless way of building them with some other tool (say, php or perl and the appropriate modules)? Am I likely to get a significant boost to performance if I keep Access in the middle for queries but move the tables to mySQL? - 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?

If you delete the row containing the maximum value for an
`AUTO_INCREMENT' column, the value will be reused with an ISAM
table but not with a `MyISAM' table. If you delete all rows in the
table with `DELETE FROM table_name' (without a `WHERE') in
`AUTOCOMMIT' mode, the sequence starts over for both table types.

Re: Mysql and security?

Perhaps you want to distribute a CD full of databases, and people buy access to specific databases. access = password It means that you don't have to create a different CD for each database, and therefore don't have to ship multiple CDs. I know some government department does that with Australian geographical maps. They send you the CD, which contains all the maps, but you have to pay to unlock the maps you need. Or at least I think that's how it works. :) 2 Regards, /|/| / | - 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?

Database/table encryption
I'm working for a company that has a paranoid client, and the client wants their database to be 'secure'. By 'secure' they mean that even if someone gains root access on the server, the data in the database can't be compromised (obtained). I can think of a couple of ways to do this, but I don't know if they're practical. The first is to have MySQL store the tables and such in an encrypted fashion, at the file layer. The second is to have the application encrypt the data when storing it in the database, and decrypt it when retrieving it. In this case, perhaps PGP could be used to do the encryption/decryption? PGP (or GnuPG) would be good, because it would only require a password from the user when decrypting. However, I suspect that the overhead in calling PGP/GnuPG for each record would be prohibitive. Perhaps there's a PGP/GnuPG Perl module that doesn't require PGP or GnuPG to be installed? (ie: has all code implemented internally, in Perl or C) Can anyone else offer any alternative suggestions, or some guidance? 2 Regards, /|/| / | - 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: Can I have two (or more) different SQL-databases on the same server?
If you mean databases others have already replied. If you mean multiple instances of the mysql server then that is also a yes. I haven't tried but I do know you have to specify a different port for the 2nd instance. This is also in the manual. - Original Message - From: "SED" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, February 01, 2001 3:01 Subject: Can I have two (or more) different SQL-databases on the same server? Hi, Can I have two (or more) different SQL-databases running at the same time on the same server (or same computer)? Does it varies between the systems? And if I can, are they all available to PHP at the same time?

Problem setting up separate MySQL server - some queries sleepuntil PHP times out
Hi, I am trying to setup a new MySQL server where I am working. The old one was on a machine with Apache/PHP4 and worked fine but recently MySQL was placing a big load on this machine so we decided to move it to its own server. I've set it up fine on a machine with Red Hat 7, MySQL 3.23.32 and it all works fine locally. SOME queries work fine from the web server to the new MySQL server and go through instantly, but others seem to be hanging. I've been testing it with the most intensive database we had on the old system. When you execute a large query on the old server ( Red Hat 6.2 / MySQL 3.22.32 ), if you watched the processlist the query was working away for about 10 seconds ( you could see the info field changing working through the query ) and then it would return the results. On the new server however, the queries seem to hang and sit in sleep mode. If you watch the processlist very carefully they are executing one 'line' of the query but then jumping back into sleep mode. Some of these large queries will eventually complete but more often they just time out. Other, simpler queries work fine on both the new and old MySQL servers. The large queries I've been using are just large select type statements, theres a couple of examples below. The queries are nested in the PHP because I need to perform tests/actions on the results from the first level of results before generating the next level. SELECT memcats.MemberNumber FROM memcats,members WHERE memcats.Category='".$category."' AND memcats.MemberNumber=members.MemberNumber ORDER BY members.Plan DESC,members.Name SELECT * FROM members WHERE MemberNumber=".$crow['MemberNumber']." AND ACTIVE=1 ORDER BY Name SELECT State,RegionID,Locality FROM regionpcodes WHERE Postcode=".$row['Postcode'] SELECT Region FROM regions WHERE ID=".$prow['RegionID'] Heres a sample processlist: Id User Host db Command Time State Info 4 root localhost Sleep 5409 34 root www.acenet.com.au ccare Sleep 4 35 root www.acenet.com.au ccare Sleep 0 36 root www.acenet.com.au mysql Query 0 SHOW PROCESSLIST Numbers 34 and 35 are examples of this, every few seconds they will reset their 'time' field value as well, this seems to be when they execute one step of the actual query.
