Replication question to MySQL list

INSERT INTO tempTableA ... SET SQL_LOG_BIN = 1; INSERT INTO nomalTableB SELECT * FROM tempTableA --- it does not work because tempTableA table has not been replicated.

Re: design help
Hi dn, thanks for replying. I suspect you're right about my 'problem' - I'm probably misunderstanding some simple SQL construct :-) Let's say I have the following tables: parts (partid int, partname varchar(255)) cats(catid int, catname varchar(255)) parts_cats (id int, partid int, catid int) To track which categories are assigned to which parts. I can use the following query to return parts and associated categories: SELECT partid,catid,partname,catname FROM parts_cats LEFT JOIN parts ON parts_cats.partid=parts.partid LEFT JOIN cats ON parts_cats.catid=cats.catid However, as I won't know how many categories are assigned to a given part, how can I: a) Form a query that only returns a list of parts that match a specifc set of categories (i.e. parts_cats has records where catid=1, 3 and 7 for any given partid) b) Know how many unique records I'm dealing with. Using the SQL above, if a part has, say, 3 categories then 3 rows would be returned. 4 categories and 4 rows are returned, etc. - how can I tell how big my result set is so that I can page through it using LIMIT? Hope I've explained myself clearly! - thanks in advance, james ps Completely OT question - how do you find your HomeChoice service? Been thinking about getting it for a while. j. At 09:39 10/02/2002 +, you wrote: The separate table idea is standard relational theory. The tbl schema might involve (1) a unique Id column (with AUTO_INCREMENT), (2) a 'copy' of whatever data from the existing tbl(s) to sufficiently identify the particular response/select box, and (3) one of the select box return values - there would then be as many rows as there were responses in the select box (n=3 in this example). The second of these must be sufficient information to uniquely identify which table entry in the original table relates to the particular select-response - these are called Foreign Keys. To retrieve all of the select-responses, you would indeed issue a SELECT...JOIN and thus be able to reassemble the HTML select command, for example. Yes you are correct (in your example) such a SELECT will produce a resultset of 3 rows. This will allow you to search on a single, or multiple (concurrent) select-responses. As mentioned, this is SOP. You say you want multiple responses but not multiple entries, but not why. Perhaps most of the 'problem' lies hidden there? =dn - 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?

Windows Version of MySQL licensing question?
I read in Paul's book that to use MySQL on a Windows platform you need to pay for it. I have downloaded a version of the server and client software from the official MySQL.com site and installed it on XP without incident. Paul also writes that the version for windows will be shareware only. This seems not to be the case I have had my server 3.23.43-nt up and running now for some months. I only use the server for my own uni work but I am curious as to what is the real deal. Anyone?

Hi folks - I am still having 2 related problems with the timezone setting for mysqld was hoping to get some help. Basically my squestions are as follows: a) the documentation says to set timezone by simply using --timezone=# when starting mysqld - but WHAT are the valid number values which time zones do the map to? b) I have tried to set the timezone using safe_mysqld --timezone=XX where I have tried various values for XX such as o1, 1, 13, 05,08 BUT near as I can tell ANY value I put in gives me GMT/UTC time (I think that's what it is) rather than giving me time offset by the given amount i entered.

Re: Tweaking MySQL on a RaQ (or any server) Help please.
Hi James, Many of the questions on this list are answered by people like myself who are users of MySQL. We are busy trying to run our own servers and put food on the table. That being said, you are wondering why your question did not get an answer, it may be the length of the message and the not-very-specific question. My guess is this one will get more answers as you asked 'where can I find the resources to help myself'. I would recommend starting with a good sysadmin book (there are many) such as: Unix System Administration Handbook, Prentice Hall This will help you manage system resources. Futhurmore on MySQL, the manual is an excellent source of information. Have you read all the information about tunable parameters in the manual? There is lots of it. Then when you have a specific question post it here. Addntl books on MySQL: MySQL by Paul Dubois from New Riders is a standard Core MySQL by Leon Atkinson Prentice Hall (Just out this year) and excellent resource and goes beyond Paul's book but and it is newer (despite the numerous spelling errors in the examples and the text). Also there are web resources: http://www.mysql.com/portal/books http://www.faqts.com/knowledge_base/index.phtml/fid/52/ Articles on MySQL in the portal section of the web site: http://www.mysql.com/portal/development/html/development-61-1.html Also one last point, time is money. If you are using MySQL in a commercial venture purchasing a support contract would be wise. They will help (at anything but the most basic level) to tune your system and the higher levels they will do it for you! The MySQL support contract is by far the best money I have ever spent on software!

Re: Problems with select
I have a (probably dumb) question. My table temperatura has two fields described bellow. snip When I try to select rows with floats, the result is an empty set. This is not a MySQL problem, nor a database one, but a general computer science one. It is almost never save to compare two floating point numbers for equality. The decimal representation you see in ASCII is not an exact representation but an approximation. Because of the way computers store floating point numbers in bunry and humans read them in decimal, the decimal value is alway rounded and there are invisible bits which can be different in apparently identical values. For floating point comparisons you should *always* use unequalities e.g. WHERE temp BETWEEN 15.75 AND 15.85.

FW: Escape a blob field.....
Hi There!
I am using mysql 3.23.41, for redhat-linux-gnu (i386).
My problem is this.
In java, I am trying to extract a blob field from a mysql table - I am
using
Byte[] somebytes = RS.getBytes(FPPICTURE);
String somestring = new String(somebytes);
This gives me a string of the blob data.
I then need to create a new SQL insert statement that will insert the
blob data stored within somestring into a table..
String sqlCommand = INSERT INTO SOMETABLE (FPPICTURE) VALUES
('+somestring+');;
However, when I attempt to execute the above query, I have a problem
because the contents of somestring contains some characters that are
illegal within a SQL statement such as a ' .
I have used PHPMyAdmin, and exported a table which has blob fields
within it. The result is a SQL string with the contents of the blob
field being escaped within the SQL query.
My question is, how can I get a blob field from a mysql table that had
already escaped any illegal charachters, or how can I encode the blob
field myself so that the mysql statement I create is valid ???
Thanks in advance,
Ian Packard

Re: Distributed Fulltext?
I did this at a previous job, and we split the data up more or less this way (we used a pre-existing item number for the split which was essentially random in relation to the text data), with a aggregator that did the query X ways, each to a separate box holding 1/X of the data. The results from each unit were paged and sorted, so all the aggregator did was do a simple merge sort on a page of the set, which was fast. On a 6M record dataset, it produced millisecond-range search results. Not exactly Google-class, but pretty good for 12 Linux boxes, two programmers, and about six weeks of effort. james montebello On Thu, 7 Feb 2002, Brian Bray wrote: It seems to me like the best solution that could be implemented as-is would be to keep a random int column in your table (with a range of say 1-100) and then have fulltext server 1 psudo-replicate records with a the random number in the range of 1-10, server 2 11-20 and server 3 21-30 and so on.

Re: opposite of PASSWORD('mypasswd').
dear friends,
in Mysql, under sql, we have the function PASSWORD('mypasswd') where we
can encrpt
'mypasswd' into a 16 character scrambled word.
which function in sql is used to decrypt the same and get back the
original mypasswd.

Re: Distributed Fulltext?
Steve Rapaport wrote: On Friday 08 February 2002 06:14 pm, James Montebello wrote: Distribution is how Google gets its speed. You say clustering won't solve the problem, but distributing the indicies across many processors *is* going to gain you a huge speed increase through sheer parallelism. True, but not enough. The BEST parallelism can do in a compute-bound application is divide the time by the number of processors. That's assuming a PERFECT routing system. (Correct me if I'm wrong here) There are actually some exceptions. Specifically if you have a very large problem set and parallelism allows you to move the problem set into a faster storage medium, you can sometimes see greater performance increases. Lets say you are doing a full text search. And you have a 20 GB full text index. It may not be feasible to build a machine with 20GB of RAM for storing the index in RAM. But it might be more feasible to store 1/20th of the index in each of 20 1GB machines. And with RAM being 1000 times as fast as hard disk. You could get a huge win. So to make the routing system + parallelism add up to a MILLION times better performance, you would need at least a MILLION processors. I doubt that even Google is doing that. Google uses thousands of processors to handle its index, and any given search is going to be spread over 100s of processors. Right, so we can expect Google to do, say, 10,000 times (10^4) better than Mysql at a Fulltext search. But in fact we're seeing a million, 10^6, being generous. It's that extra factor of a hundred (more likely a thousand, my estimates were very generous) that I'm getting all fussy about. Asking a general purpose RDBMS to be really good a 10 different things is asking a bit much. Fulltext searches are well down the list. Here we get out of the realm of hard numbers and into opinions. But here's mine: If mysql bothers to support fulltext searches, it's presumably because there's some demand for them in some circumstances. The level of scaling and optimization that could reasonably be expected: What it takes to make the feature useful (i.e. perform similarly) in similar cases to other Mysql features. With a regular index, I can do a hash lookup on 23 million records subsecond. With a fulltext index (on a small field, only 40 characters) my time slips to 3 to 180 seconds. That extra little factor of 100 is my problem. Distributing over 4 processors wouldn't really help much. And because people don't always type a company name the exact same way, FULLTEXT really is the best way to do this. So Monty et al, my request is this: please put on the wish list, enhancement of FULLTEXT search to approximately match the performance of an indexed search on 25 million records, on the same hardware and with other things held equal.

I know it's possible to use the DISTINCT operator to show only one of the identical records in a result, but that does not remove one of them from the database. One thought that I had would be to add a unique number to each record, and that could probably be done manually, one record at a time, but is there a way to automate the process so that unique numbers could be assigned with one command?

Embedded Quotes
The mySQL manual says that embedded double quotes within a single quoted expression (as in 'OHara') need no special treatment. However, when I try to update a data base field using such an expression, as in: UPDATE table set col1='OHara' the result I get is that everything to the right of the double quote is deleted. In other words, the result of the update is just the letter O in this example. I get the same result if I use the escape character as follows: UPDATE table set col1='O\Hara' Is this behavior expected??

Quick SQL design help
Hello MySQL users I was wondering if one of you could advise me on the best solution to a problem I'm having - I'm sure this has been done before but haven't found anything in the archives. Basically the problem I am having is how best to handle multiple values for a specific column, in this case the values in question are coming from an HTML SELECT MULTI box processed by PHP. The way I have been doing this so far is to have a delimited value stored in a varchar column, e.g. If my select box returns the values 2,4 and 7 I insert into my table the string '|2|4|7|'. Surely there must be a better way than this - but it escapes me. In this setup the only way to match a specifc value when searching is to use the query: SELECT dataid,title FROM table WHERE category LIKE '%|4|%' Which obviously has a huge performance penalty - and of course you can't JOIN against any of these values. The only other way I thought of was to use a separate table for the category entries: SELECT dataid,title,category FROM table LEFT JOIN table_categories ON table.dataid=table_categories.dataid But in the example above this would return 3 entries, which I don't want, and I can't select a particular dataid which satisfies more than category, e.g. has categories 4 and 7 (i.e. for the example above the LIKE statement would be: WHERE category LIKE '%|4|%' AND LIKE '%|7|%'). Any ideas? Please help!

However relational logic suggests that the way to set up a linkage between tables is to show this in dynamic logic - your SQL statement, eg SELECT * FROM tbl1, tbl2 WHERE tbl1.PrimaryKey = tbl2.ForeignKey; will produce a result-row for every intersection 'match' between the two tables. One of the MAJOR advances of relational databases over their predecessors was this move 'away' from structural 'connections'. However these have been maintained as 'features' by some, usually to promote speed/efficiency. Speed/efficiency is a minor issue. Integrity constraints are used to prevent people from writing queries that violate relational integrity rules; e.g. create orphan records. And integrity constraints are unrelated to joins, except in the most incidental way. It is possible to use them to create joins, but that's not why they're built into databases.

(@sys:=SUM(IF(DISPATCHLOG.Details = 'O/E by System' AND
DISPATCHLOG.ID_STATUS = 30 AND ORDERLINE.Step = 1,1,0))) AS 'System',
(@can:=(SUM(IF(DISPATCHLOG.ID_STATUS = 43 AND ORDERLINE.Step =
1,1,0))-SUM(IF(DISPATCHLOG.ID_STATUS = 73 AND ORDERLINE.Step = 1,1,0 AS
'Cancelled', (@tl-@wb-@sys-@can) AS 'Balance' FROM ORDERHEADER LEFT JOIN
ORDERLINE ON ORDERHEADER.ID = ORDERLINE.ID_ORDERHEADER LEFT JOIN DISPATCHLOG
ON ORDERLINE.ID = DISPATCHLOG.ID_ORDERLINE WHERE (ORDERHEADER.AvailableAt
BETWEEN '[param:Start Date]' AND '[param:End Date]') GROUP BY 'Date' ORDER
BY 'Date' DESC
but on mysql Ver 11.13 Distrib 3.23.36, for pc-linux-gnu (i686) it doesnt
calculate the balance column
--
SELECT @com:=SUM(PAYROLL.Amount) AS 'Commissions', '0.00' AS 'Other',

Note: about the use of [param:Variable], these select statements are stored

Hi Is there any reason to reboot MySql periodically? Short answer: No. My server has been up for just under 6 months without a reboot, That is not unusual. and some of the queries are noticeably slower. This may well be because the data has grown, but I wondered if there is any memory leakage at all. If you have deleted from many tables, OPTIMIZE will be your friend.

Re: Distributed Fulltext?
Why is it that Altavista can index terabytes overnight and return a fulltext boolean for the WHOLE WEB within a second, and Mysql takes so long? I don't know about Altavista, but if you read up on Google, they do indeed do some sort of spreading of keywords across multiple machines - last I saw they had over 10,000 machines. But you have to ask the question as to whether this would be an appropriate development for MySQL. This would seeem to me to be a very complex development of interest to a very small subset of MySQL customers. MySQL, it seems to me, specialises in doing the mainstream database manipulations used by many people simply, quicly, and (my most important criterion) reliably. Such a development would, IMO, be away from the whole trend of MySQL, and shouldn't happen before triggers, stored procedures and the like - if ever. A multe-machine distributed database is a wholly different animal - IMO again. If I was going there I wouldn't start from here - it would need a clean brain look at the whole problem. If you really need such searches, Google survives by licencint that technology - speak to them.

Re: Distributed Fulltext?
Ooops, factual error: If, say, Google, can search 2 trillion web pages, averaging say 70k bytes each, in 1 second, and Mysql can search 22 million records, with an index on 40 bytes each, in 3 seconds (my experience) on a good day, what's the order of magnitude difference? Roughly 10^9. Google has only 2 Billion with a B web pages. So the order of magnitude difference is only 10^6. But that still leaves a mysql Fulltext search a MILLION times slower than Google. Someone correctly pointed out today that it's not Mysql's job to be Google, and I agree. But it seems to me that it would be fair for mysql to be able to handle searches in under 1 second for databases 1 millionth the size of Google. All I want here is a decent flexible phone book lookup, not a search engine. -steve - 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: I must ask.
Hello André I am playing hard with mysql, cause my ultimate objective is to make a big databank for a game. I notice that i cant find a way to make relations beteen tables. Must i do it also with PHP ? Just to confuse you, the mathematical jargon for table is relation... May I suggest that you search the web for some tutorials on the use of SQL in general/MySQL in particular - it will help your playing, and ultimately your game. There are some RDBMS-es that implement SQL to the point of apparently setting up a construct that links tables - foreign key based data integrity being the first example that springs to (my) mind. However relational logic suggests that the way to set up a linkage between tables is to show this in dynamic logic - your SQL statement, eg SELECT * FROM tbl1, tbl2 WHERE tbl1.PrimaryKey = tbl2.ForeignKey; will produce a result-row for every intersection 'match' between the two tables. One of the MAJOR advances of relational databases over their predecessors was this move 'away' from structural 'connections'. However these have been maintained as 'features' by some, usually to promote speed/efficiency. Perhaps this is a major interest for you/gaming - but in which case, you will find that indexed-file systems will likely be a better/faster/smaller option. (?) An original objective, and one well worth bearing in mind today, is that relational technology allows one to establish a 'relationship' between items of data today, that was not anticipated/designed into the system when it was first built n-years ago.

Re: Retrieving a numeric series from a SELECT
Hi, Fellows! Sorry for my poor english. Thats why I can explain myself properly. :- ) What I really want is a calculate column with consecutive numbers from n to m, where n can be any number, and m depending on the result of the WHERE clause. I need to print pay orders for students, this pay orders use a consecutive control number, the criteria to select students use to be variable. Example: SELECT colnum, id, name FROM students WHERE status='OK' (4 rows selected) or SELECT colnum, id, name FROM students WHERE grade=1 (230 rows selected) colnum must be the same number that is printed in the pay order. The next pay order on the printer is 15000, then colnum of the first row of the SELECT must be 15100, the next row 15001, and so on. you get it? I remember that the sample i saw in this SQL list only used a SELECT statement without a table, or whitout a memory variable. it was only a SELECT something, and it returns a consecutive serie from 1 to 100.

And I don't expect the data format to change. BUT: thought experiment: When Mysql decides to generate a FULLTEXT index, it is using an index file, the .MYI file, which can have ANY FORMAT it wants to. If the .MYI format is poorly optimized for fulltext searches, they can improve the format. They can even introduce a new index file type .MYF solely for optimizing fulltext searches. None of this need have any impact on the data file format or the SQL search optimizations, and yet it could still improve the search speed for fulltext. It might not help as much for the slow indexing, but it could certainly improve the performance of the search. Thinking out loud...

Re: Set up help needed
If you want to get the most out of MySQL, then you really need to learn to use the command line tools. MySQL has the easiest to use tools and language of any database I've used. SQL allows you to do really powerful things easily. Download the Windows version and install it. You can use the mysql client to connect to the remote server from your Windows box. Alternatively, and probably even easier, download an SSH client for Windows (do a Google search for putty) and SSH in to your Linux box. Then use the mysql client locally there. For long SQL queries like creating tables, I find it useful to type them up in Notepad and then paste them into the client. If you made a mistake, fix it in Notepad and paste it again. mysqldump is also a very handy tool for viewing a table's schema. What is the best or easiest client to set up on my NT4 workstation so I can connect to the MySql server and create tables, etc via scripts? I tried downloading one or two from the MySql site but none of them seem to have any instructions as to how to set them up or get the connection going. - 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: How to connect in non-interactive mode
Dan, Thanks for your response. I see what you're saying. However, in our case, the only 'clients' connecting to the MySQL server are software modules, no humans. Well actually, humans too, but only through our software modules. So no clients getting disconnected until the server is restarted is what we want. Some of them, in this case our system logger, may have long periods of inactivity (ie, overnight, more than 8 hours, no logs to store in the database, so no activity on that client connection). So... if there is a way to set the interactive_timeout to infinite, that would be most handy. Regards, Becky Daniel Rosher wrote: If you set the interactive_timeout to infinite then no clients will get disconnected until the server is restarted. I know the perl DBI allows for a client to implement ping ($dbh-ping) ... this will reset the timeout for that particular client, allow the client to check for connectivity, without having to make ever client connect forever!!.

Delete oldest data
I'm using MySQL-Max-3.23 and I need to keep a table from exceding a certain size. I plan on running a cron job that checks the size of the table and if its close to the max, executes a delete statement. The problem I have is that 3.23 doesn't support delete from .. order by .. -- this was added in MySQL 4.x .. Ideally I'd use DELETE FROM table ORDER BY datestamp ASC LIMIT 1, but of course this doesn't work. How are people doing this in 3.23.xx?

binary installation questions
OK, here's the setup: Using the binary package in mysql-3.23.47-sun-solaris2.8-sparc.tar.gz all unpacked, untarred (with gtar, yes), etc. I follow all the instructions in the INSTALL-BINARY file, with this one change: I intend for the user to be mysql_st, not mysql. But according to note #4 in the INSTALL-BINARY file this should be okay, although it does not say whether this necessitates any changes elsewhere in the installation. Oh, and also the data directory in /usr/local/mysql is softlinked to another drive with much more space. Permissions on that directory are set to the mysql_at user with the rest set to root, as described in the INSTALL-BINARY file. And yes, I ran the scripts/mysql_install_db script. OK, so here is what I have now: I can connect to mysql as mysql -u root and no password is needed. So according to page 414 of the MySQL book I need to run mysqladmin -u root password to fix this. BUT!! Everytime I try to do this, whether as myself, as the mysql_st user, or even as root, I get this: [4:17pm] cindy@steph /usr/local/mysql/bin/mysqladmin -u root password kool /usr/local/mysql/bin/mysqladmin: unable to change password; error: 'You must have privileges to update tables in the mysql database to be able to change passwords for others' At the same time: [4:17pm] cindy@steph mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 15 to server version: 3.23.44 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql works fine (again, no matter who I am) Eh? Now, what I'm guessing is that I should be using GRANTS to set this up, as outlined in the online manual in section 4.3.6 (Setting up Passwords). But before I muck around much more, I'd like some assurance that I'm on the right track, or whether I've flubbed something else that should be taken care of instead. Particularly because according to this section, doing the insert into the user table should be exactly equivalent to the mysqladmin command that fails above. I also wonder if maybe the INSTALL-BINARY file should include a brief note on setting up a root password, even if just a pointer or whatever.

More like Äpplen och Apelsiner, that is, different but similar. You Swedish guys should know. Thanks for answering, David, I appreciate the attention from a founder. I also appreciate your point that Google is updating continuously and therefore not always caught up to the current state of the web. But isn't that a problem with indexing speed, not with search speed? Their search speed is still amazing, as is Altavista, and most of the other engines. Your other point about exact vs. approximate answers is unclear, I expect that Google's answers are exact for their currently available indexes at any given time. But even if they are approximate, I'd be happy with that too. The scoring on a FULLTEXT search in Mysql is exact but based on a formula that is approximate anyway. No, MySQL returns all data according to a search. Web engines return what they they find on one search machine. So you can get different results with Google every time you hit refresh if you are routed to different machines. This had happened to me when I was looking for the number of matches and not the result itself. So we should try to make fulltext searches with a limit between 10 and 100 be fast to be closer to google. I have also head about some other things web search engines do since I know some people at FAST but I have forgot that already. I'll summarize this thread best I can. From the math I used, we started with my estimate of 10^9, which was mistaken. The real figure was 10^6, that is, Google searches fulltext about a million times faster than Mysql. Then we used Google's 1 machines +DRAM indexing to reduce the gap to 10^2, or 100 times faster. I would say we should reduce it even further but that could be discussed. It turns out that 100 times is about the factor that is causing my application problems. If it just ran 100 times faster it would be about as fast as a regular indexed search, and I'd be happy. A few people suggested that Mysql shouldn't try to be faster, I (and some high-support customers like Mike Wexler) disagreed. And Alex Aulbach, bless him, actually did his homework and showed that things could be much improved with smart index techniques like inverted files. We will try to make every feature as good as possible. But we do have limited resources. Then Sergei Golubchik wrote back to say he had taken some of the good ideas and inserted them into the TODO list, although he had higher priorities at the time. And I was satisfied for now, although my application still isn't working satisfactorily due to a really slow and CPU-hungry FULLTEXT search. Well there is always the option of sponsoring further fulltext development. We have a guy who has been working on the GNU fulltext engines who is interesting in working with MySQL fulltext. But for the moment we can not afford it. So if some of you are interested in sponsoring this (or know about others who might be) write to [EMAIL PROTECTED] I think that's our story so far.

Re: outer join + count() + group by
Hi, Yes I have made some mistakes. There was problem with the outer join. It should have been ad outer joined to review, not the other way. I didn't notice the first tabel person in the query. Try the following with two tables ad and review and later add person table. We don't know the columns of person table to relate with the othere tables. select ad.id,sum(review.id is not null) from ad left join review on ad.id=review.id group by ad.id; OR select ad.id,sum(if (ifnull(review.id,0)=0,0,1)) from ad left join review on ad.id=review.id group by ad.id; the id column can't be null, it's defined as varchar(16) not null. Even though the id column is defined as not null and there is no null values in this field of review table, the value returned by the query for this column can be null for outer joins. In fact we use outer joins to return a row even if there is no rows in the second (right table in the outer join ) with all the columns of this row with null value. The above query (first) behaves like this: It will return one row each for each row in review table which has a corresponding id in ad table. Additionally it will return one row for each row in ad table for which there is no corresponding row in review table but with review column value as null. So for each id in ad for which there is no reviews the review.id will be null and the expression (review.id is not null) will return 0, for which there is review it will return 1. Hence summing this on this expression should give you the right answer.

Re: Distributed Fulltext?
[comparisons to Google...] While any speed up with a full table fulltext search would be helpful and useful, there are instances where the search is intersected with another column and the problem of search is therefore more complex but also leads to potential optimizations. In our case we rarely do searches that use just the FTS index. More commonly, we do searches based on other columns and a FTS indexed text column. The WHERE clause restraints on the non-text column usually eliminate 99% of the rows. Fulltext indexes can not be combined with numeric columns in a single composite index, so as far as I can tell, MySQL performs the FTS then filters the results to meet the WHERE conditions. I believe the required amount of the index to be paged into main memory is much larger than might otherwise be needed (since the indexes are larger than available memory, and there a zillion other tables accessed simultaneously, this tends to effect all queries). So besides the obvious desire to lower the size of indexes, it would be beneficial if a combined index could lower the number of matching rows and the amount of the index needed to be in memory. I actually find it odd for people to not be using secondary columns in a fulltext search, other than to do something like Google (which does not lend itself to using SQL in the first place. Of course, I have a myopic view stemming from my own requirements and experience. All that said, I'm glad to have the FTS we have. Thanks Sergei for such a wonderful improvement to LIKE '%word%'!

RE: Request for help in testing new replication code in 4.0.2
I have finished a script that takes the bit keeper sources and makes MySQL-4.0.2 RPMS for Redhat 6.x and apparently 7.X as well. I can put these up on our site for download if you want. They might get others trying the code out. I use the spec file included with the source code. I'll put it up if it's something you might find useful. -Original Message- From: Steven Roussey [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 12:41 PM To: 'Sasha Pachev' Cc: 'Mysql' Subject: Re: Request for help in testing new replication code in 4.0.2 * If you want to do it this very moment, read the instructions at http://www.mysql.com/doc/I/n/Installing_source_tree.html and install a pre-release 4.0.2 MySQL on your test server. You may also wait until 4.0.2 is released, but in that case, replication in 4.0.2 may have a bug you could have caught on your system and it will not be fixed until 4.0.3. Is that possible to provide a binary snapshot of the pre-release? This can be done with some simple shell scripting, I think. I always found the one I build myself is about 30-50% slower then the official binary. I think that's related to the debian patched glibc-2.95 I am using. Hi, I have to agree with this. I don't want to have to factor in RedHat's 7.2 compiler oddities (which one to use?). Some software projects have a machine to do regular builds on a schedule. This would be ideal. You would find more people testing it. You might just do it in special cases like this one. Testing the new code is relatively easy, and does not require risking the stability of your application by running alpha code. Yes and no. Taking down a server and copying gigs of data can take down a service for a long time (moving gigs of data just is never fast, and the machine I'm going to use has lots of power but no RAID). I don't have time to download and install gcc, bitkeeper, autoconf 2.13, automake 1.4, libtool, m4, and mysql today, but I'll try and get to it this week. Taking down the server will have to wait until maintenance windows over the weekend anyhow. Our test plan for MySQL 4 is as follows: 1. Serialized writes (i.e. replication slave) for two weeks (or about 1 billion insert/update/delete type queries) with no crashes. 2. Everything. We will have the app send duplicates of all queries to the mysql 4 server, but will automatically halt when mysql 4 crashes. We will keep trying this until mysql doesn't crash for a week. 3. Check that the two servers hold the same information and return the same results from queries. With the type and volume of queries that we have, mysql alpha versions either fail within minutes/hours/days or they don't fail at all. We certainly are not the biggest user of mysql, but historically, we have been able to push it hard enough to crash. Not the stable version though. Thankfully, that takes a licking and keeps on ticking. :) Eventually (spring/summer), we will move the main server to v4 and keep the slave around as a live backup. I've been wanting such a slave for a long time. Stopping the slave to make a backup would be great. Not to mention faster fulltext and order by DESC.

Regarding Mysql Database file system
I need to create a database in MySQL that I need to bundle with my program for distribution. The user will have its own copy of MySQL running. User using my program will not bother about database issues and the bundled database will provide him, through my application program GUI, to enter/retrieve data. For this I have thought of using the file based database ie some file(s) will be bundled that are MySQL database. The configuration to tell where the MySQL is running that will operate on the file system database bundle will be done before running the program. How to create such database in MySQL. An analogy could be the way MS-ACCESS creates the .mdb file that one can use anywhere configuring the ODBC32 on windows. For creating such database in MYSQL whether i will use INNODB Database or ISAM table. if using INNODB database it is possible then from where i will get mySql that support INNODB(which version of mysql for linux and windows).

request for help with multiple JOINs
Is there anyone who could help me with this simple query. Did i ask anything in a wrong way because I still got no answers to my request? SELECT at.name, av.value, at.unit, at.id, a.product_id FROM attribute_type at LEFT OUTER JOIN attribute a on (at.id = a.type_id) LEFT OUTER JOIN attribute_value av on (av.id = a.value_id) WHERE (a.product_id = 21 OR a.product_id IS Not NULL OR a.value_ID IS Not NULL OR a.type_ID IS Not NULL) and the result: | name | value | unit | id | product_id | | height | 10| cm | 1 | 21 | | width| 20| cm | 2 | 32 | | width| 30| cm | 2 | 40 | | diameter | 222 | cm | 3 | 21 | Number of Results: 4 I only want to have attributes for one product_id (e.g. 21). However, every attributetype available has to be in the result and any corresponding value or NULL. So my preferred result should look like that: | name | value | unit | id | product_id | | height | 10| cm | 1 | 21 | | width| NULL| cm | 2 | NULL | because width is for this product still empty but should be available to fill with a value | diameter | 222 | cm | 3 | 21 | Number of Results: 3 Any chance to achieve this? I have 3 tables to describe attributes for a product database. e.g. attribute_type: ++--+--+ | id | name | unit | ++--+--+ | 1 | height | cm | | 2 | width| cm | | 3 | diameter | cm | ++--+--+ attribute_value: ++--+ | id | value| ++--+ | 1 | 10 | | 2 | 20 | | 3 | 30 | | 4 | 222 | ++--+ attribute: ++--+--++ | id | type_id | value_id | product_id | ++--+--++ | 1 | 1| 1| 21 | | 2 | 2| 2| 32 | | 3 | 2| 3| 40 | | 4 | 3| 4| 21 | ++--+--++ In a web form where I edit the product, there is also an attribute section where I would like to give certain attributes values specific for the product. The problem is when I associate values to attributes in one product, the same attribute in other products is hidden (not in the result of the query). Therefore I would like to list all attribute_types for each product regardless if there are values assigned or not. I used the following query and I think there must be something wrong: SELECT at.name, av.value, at.unit, at.id, a.product_id FROMattribute_type at LEFT OUTER JOIN attribute a on (at.id = a.type_id) LEFT OUTER JOIN attribute_value av on (av.id = a.value_id) WHERE (a.product_id = 21 OR a.product_id IS NULL OR a.value_ID IS NULL OR a.type_ID IS NULL) regards, Andreas - Andreas Habereder private: [EMAIL PROTECTED] mobile: +49 172 838 7771 - - 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: Windows Version of MySQL licensing question?
David Ayliffe a écrit : I read in Paul's book that to use MySQL on a Windows platform you need to pay for it. I have downloaded a version of the server and client software from the official MySQL.com site and installed it on XP without incident. Paul also writes that the version for windows will be shareware only. This seems not to be the case I have had my server 3.23.43-nt up and running now for some months. I only use the server for my own uni work but I am curious as to what is the real deal. Anyone?

Re: Probably OT - SQL join help needed
Hello Robert, Hello experts, I've got a small problem with an sql query here that's got me completely stuck. In my MySQL database I've got two tables here that have identical design, e.g. table 'detail' - columns sales-order, quantity, part-number, price, date-sent and table 'archived' - columns sales-order, quantity, part-number, price, date-sent. Detail is for 'active' orders, and Archived is for fulfilled orders. Now some genius here wants to see all the records that reference a particular part number, irrespective of whether in archived or detail. My current approach is to create a temporary table with all the suitable records from detail, add in any suitable records from archived, and then do a select * query from this temporary table, before dropping it. Now it strikes me that this isn't a very smart way to do this, and it's probably achievable via joins but, try as I might, I can't get the system to do it. Anyone got any bright ideas/suggestions? If the tables are identical then UNION may be what you're looking for: 6.4.1.2 UNION Syntax (MySQL 4.0). For every user genius who forgets to put something in the spec up-front, there's a computer guy who's smarter!

That's bad.
I presume (again ??) that the above line is trying to strip out all

Actually it's trying to strip out every database name which contains
two digits in a row. That's clearly not ideal. We need something
more specific there.

What it should be doing is identifying every file which isn't in a
two-digit sub-directory inside a database directory.
It should read:
my @non_raid = grep { ! m:/\d{2}/[^/]+$: } @$files;
I've sent a patch to internals.

Re: ignoring in ORDER
Hi Abdul, Can Mysql ignore alphabet , like 'the' when ORDERING a name. A sample : I have a table (first_name) : - The test. - Falcon - The Armageddon - Battle When ordering it will be : Battle Falcon The Armageddon The test. Can it be like this : The Armageddon Battle Falcon The test. Is that possible? =Anything is possible! =This is a common 'problem' in the library world where in the context of titles 'the', 'a', 'al' are considered 'noise-words'. Some of the 'library' scripts available on the various support/tutorial sites may offer assistance. =Here are three choices: 1 regimentation: insist that all title data entered, is expressed in a sequence-friendly fashion, eg Armageddon, The; 2 smart data: have two title fields in your db. One which is the title straight off the cover. The other which is a 'sequencing field' - sometimes with noise words removed/words re-ordered, sometimes exactly the same. Users should be presented with the former, but the RDBMS is programmed to use/sequence using the latter; 3 smart queries: (this is more of a challenge) look up IF() [6.3 Functions for Use in SELECT and WHERE Clauses] and rewrite the query so that if the title commences with a noise word miss it out of the sort process, eg if the left three characters are the sequence using only the Arrmageddon part. =Regards, =dn - 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?

Any help will be appreciated. Well done, you've successfully negotiated half of the 'traps' inherent in using LOAD DATA! I'll take a flying leap into the void and suggest that you are using Windows! Windows terminates lines in text files with CR and LF characters. Unix however uses only LF (and Mac only CR - but that's another story).
