RE: Updating a field with the result of a select
Is it possible to update a field with the result of a select.
For example:
Try:
SELECT @newbalance := ordr_order.total_cost - sum(ordr_payment.amount) FROM
ordr_order LEFT JOIN ordr_payment on ordr_payment.ordr_order_id =
ordr_order.id WHERE ordr_order.id = 1;
UPDATE ordr_order SET balance = @newbalance WHERE id = 1;
UPDATE ordr_order SET balance = ('SELECT ordr_order.total_cost -
sum(ordr_payment.amount) FROM ordr_order LEFT JOIN ordr_payment on
ordr_payment.ordr_order_id = ordr_order.id WHERE ordr_order.id = 1')
WHERE id = 1
This doesn't work because it's setting balance to the text of the query, not
the result of the query itself. Since balance is probably not a string type,
it gets converted to a number which probably ends up making it zero. If
MySQL supported subselects it might work except without the single quotes
around the query.

RE: Most Performance, Opinions ?
regarding mysql_pconnect() we haven't tried that, but the nature of the site suggests it would need like 500 apache deamons connected all the time. And that's a lot of sort buffers and stuff beeing allocated for each one of those ? Not if you disable keepalive requests, which I do on most web servers with heavy PHP and MySQL usage. It doesn't impact performance on the client side much since we keep our images on another server which can have keepalives enabled. You said you had messageboards, guestbooks, etc. Do any of these scripts use something like... SELECT table1.stuff, table2.stuff, table3.stuff FROM table1, table2, table3 WHERE (required constraints for joins) AND table1.messageboardid = '#' ORDER BY table1.timestamp DESC LIMIT 5; ? On large tables, this will lock the table for a long time since MySQL can't follow indices in reverse order, so it ends up having to do a full table scan. I have found that breaking it into two separate queries has improved performance considerably: SELECT id FROM table1 WHERE messageboardid = '#' ORDER BY timestamp DESC LIMIT 5; SELECT table1.stuff, table2.stuff, table3.stuff FROM table1, table2, table3 WHERE (required constraints for joins) AND table1.id IN (ids taken from previous query, separated by commas); This reduces the amount of time MySQL will lock the table, since with the first query it will do the full table scan on all 3 tables involved in the join and will keep all 3 tables locked for that time. I have seen times where the first method with one query takes 10 to 15 seconds to execute, while the second method with two separate queries both take 0.00 sec according to the MySQL command line client. - 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?

After you type it in, the server will scramble it and check that the scrambled value matches the scrambled value stored in the database -- but you can't intercept that part of the process and insert the known scrambled password to be checked. It's called bruteforcing... knowing the scrambled password, you can encrypt every possible password and compare it to the scrambled password to find the original password. Either that or the scrambled password is encrypted by the client then sent for comparison, but I doubt it. - 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: programmatically getting field list from a table
Is there any way -- using either MySQL directly, or (ideally) using the DBI perl module -- to get a list of fields from a (possibly empty) table?

RE: Is last_insert_id reliable?
$sql4 = SELECT hits.hit_id as pixels from hits WHERE hit_id=LAST_INSERT_ID();; $result = mysql_query ($sql4, $connection) or die(error # . mysql_errno() . : . mysql_error()); $row = mysql_fetch_object($result); $pixels = number_format($row-pixels); It's staggering the difference in speed. But if I sit there and hit refresh on the browser, I get wildly different values for $pixels. It jumps around the actual number by +-10 or 12. The first method is precisely the same every time (unless a hit is recorded in the interim). Am I doing something wrong here? Can I not count on MySQL to know how many rows it has recorded in a table? Any idea why that select statement would select a different row each time? From http://www.mysql.com/doc/M/i/Miscellaneous_functions.html: The last ID that was generated is maintained in the server on a per-connection basis. Since LAST_INSERT_ID() works on a per-connection basis, and since you are most likely using persistent connections, each reload of your web browser returns a different instance of the http server and therefore a different persistent connection. The best way to do it would probably be to update the last id in the table right after inserting the row (update othertable set row = last_insert_id() where yadda yadda yadda). - 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: Re[2]: LIMIT with mysql_num_rows
He wants to know the maximum, like on a search for mysql at google it says Results 1 - 10 of about 2,580,000. He wants to know that 2,580,000 number without doing another query. I don't think that's possible. Of course it is. That's what I do all the time. That's what I was talking about. I am looking at the result of my query. Then I know how many I have. I won't and cannot show all of them, if there are too many. So I check and repost that query with a LIMIT constraint. I said without doing another query :-) Sure you can do count(*) beforehand... Also, you can't really do select * from table, get the number of rows, and just stop fetching rows after your limit is reached, cause that would waste the resources of preparing the entire result set. One thing I would like to know is how Google does about 2,540,000 instead of an exact number (does it just get the exact number and round it off, or does it do an estimation that is somehow less resource intensive... then again I think they have some funky system so that their database of words fits in ram). - 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 create table with unique 2 column tuple
ALTER TABLE tblname ADD UNIQUE (column1, column2); The index will automatically be used if you use it in your WHERE clause in that order. If you want to do fulltext searching on those columns, repeat the query with FULLTEXT in place of UNIQUE. Hello, I'm trying to create a table with columns A, B, C, D such that values in columns A and B are not unique but if you consider them as a paired tuple, then for every row, value in col A, value in col B is unique.

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: (clipped) produces a table with 1 rows each containing an integer. Then we do: mysql SELECT * FROM mytable ORDER BY RAND() LIMIT 5; (clipped) 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. Watch out though. 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?

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??

RE: MySQL compression?
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? A simple gzip wouldn't add too much overhead to the system, and you could still have clear-text indexes. - 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?
