Can someone tells me wich one is better ? I know that InnoDB have foreign keys support, but I deal very well without then since now. My interests are justified becaus eI got out of a very old struct ( DBM + Text Files ) and jumped head first into MySQL - MyISAM tables, but my site has a good deal of visitors ( about 30.000 unique visitors by day ) and speed and reliability are my primary concerns. I plan to use replication in MySQL, and I would like to know if InnoDB is better than MyISAM for this. MySQL replication works with InnoDB type tables, and is currently used at several sites. InnoDB Hot Backup (non-free software) makes it possible to set up a new slave without stopping the master or setting any locks on the master. This is a useful feature at sites requiring high availability. One note here is that transactions aren't preserved for replication with InnoDB, so you loose part of one of the major advantages of InnoDB. Rollbacks are O.K., since I don't think that goes out to the slaves until the commit, but if the master or slave goes down after part of a transaction is sent to the slave, you get a partially committed transaction on the slave. How critical this is depends on the application, and still is no worse than MyISAM which has no transactions to begin with. I think Heikki Tuuri has mentioned plans to get this fixed, though I think I remember that he said that the problem was in MySQL, not in the actual InnoDB code, which makes sense. A potential embedded license buyer is interested in getting this fixed. If the deal is closed, we may add the commit marks to the binlog rather soon. Have you ever heard the old saying, If it ain't broke, don't fix it?.bg If your website is mainly for read access to your database then you're not going to need InnoDb. Agreed 100%, but it doesn't hurt too much (except for index sizes) on readonly databases, so on our production system, we standardized on InnoDB for all tables for consistency, though we will allow for exceptions for tables that need features that aren't in InnoDB yet, such as full text searching. InnoDb inserts (for a single user) are much slower (for me it is around 10x slower) than MyISAM because InnoDb does a lot more work. This was not my experience. Without batching the commits, InnoDB lost out to MyISAM on our initial testing by about 1.5x rather than 10x. However, when I committed every 100 or so inserts, InnoDB beat out MyISAM by a small (25%) margin. This was with a single user hitting the database, a perl program that read in a text file, split it into fields, and stuffed it into the database one record at a time (identical programs except for handling the commits()). Now, this wasn't normal database activity, pure inserts into a freshly created table, but the results were still quite impressive. Also, I'm dealing with single-user activity, so there may have been some differences there as well.

MySQL spanned over several systems
Hi, I would like to try to implement a MySQL server that is spanned over several machines (a sort of database cluster) - as this is only a test, I am not too woried about the end OS, but I will probably use a Mandrake 8.1 or 8.2 Linux distribution. I have found in the manual information about running several servers on the same system, but nothing on running one (or several linked) servers that can run queries on a database distributed over several systems... Any information, passed experiences, or links to ressources on the web will be greatly appreciated.

SELECT ... LIMIT n,-1
Hello, I've been looking for a way to select and access all result rows starting at a specific offset. The according select clause with LIMIT n,m comes to mind, but unfortunately the current documentation is not very explicit concerning the appropriate value for m under these circumstances. What I'm looking for is a way to specify that for a query that would return x rows when not limited, I'd like to see X-n rows, starting at row n. All this without knowing X in advance :-) Tests with mySQL 3.23.37 on Linux shows that SELECT LIMIT n,-1 will achieve the desired result. Is this a supported approach, despite the fact it isn't documented, and may I expect this to work in future versions? Is there a different approach to this? And, last but not least, could the documentation be updated to reflect this issue? Thanks in advance.

Re: Do any of your applications work?
Ditto here. If you have a support contract, then this is not the channel for seeking support, since it's a free mailing list. And anybody would need more information than you provided to solve the problem. Did you try to install a binary version? Did you try to build from source? MySQL is installed on millions of servers around the world. So, yes, the applications work and work well. I am not, by any means, a guru and I have installed MySQL on my Linux box and run it for a couple of years now. Having said all of that, you are welcome to support from this list, if you want it, but you ought to provide more detailed information. This side of MySQL is a community of volunteers and not a business. It doesn't do a whole lot of good to make threats and demands here.

corrupt .FRM files?
Yesterday we discovered a strange problem with our database running on MySQL version 3.23.45 on a Linux OS version 2.2.16 The MySQL database had been running perfectly with a PHP interface on the web since january 30th and records were added normaly. Now suddenly the MySQL server is brought back into the state of March 11th, which means that all data since then are not shown. It seems that there is a problem with the permission to files of DB. there a solution on how we can fix or repair DB - files? Also does anyone have ideas on what might have happened.

InnoDB and lock wait timeout
Hi. I have a question about rollbacks and innodb. Suppose that a query begins with begin. Then a couple inserts happen but before the commit statement is executed, the client hits stop in the browser. What is going to do the rollback? If there is a persistent connection, is it going to wait for 8 hours or so and what would happen then? Is there a significant increase in speed using persistent connections in MySQL? I am using PHP and I am cuious how one would do a persistent connection example. Does php would keep a class loaded in mem like java would? It doesn't sound plausible since php is loaded with an apache thread, which gets recycled every now and then, leaving the connection open on the mysql side but never used by apache agian. What are some approaches to solving these issues?

RE: InnoDB and lock wait timeout
Hi, Generally, an apache setup will kill a PHP enabled page when it has run for 30 seconds. Also, when a php script exits, all connections to the database are closed, so somwhere you need to keep the results of your script somwhere (hidden HTML variables, URI string), otherwise, when you change pages (and scripts of course), you lose your connection... and the transaction will probably abort... IMHO, you can only use a transaction within 1 PHP program (therefore within 1 page only), and remember your 30 second execution limit). If you are implementing a PHP / HTML application, I would guide the user over PHP enabled HTML form pages, and pass the result via a post or a URI string to the next page, etc. When you have all the info that you need, you send all the information from your previous pages to 1 parser script, which inserts all info into the database, with or without a transaction. This is the price you have to pay for a stateless connection - Your script is only active when your page is active. Hope that helps !

If there is a persistent connection, is it going to wait for 8 hours or so and what would happen then? When the user hits the STOP button, your script (most likely) will have no idea that the browser closed the connection until it tries to send it some output, at which point it would probably receive SIGPIPE or some kind of indicator that the client is gone. By default, applications that receive SIGPIPE will terminate (Broken pipe). The connection to the mysql server would be broken, and the mysql server would issue a rollback. If your web server does any buffering, you may not know until the entire page is sent that the client disappeared. Your environment may provide different default behavior, but you should be able to modify these things to taste if you're willing to get low-level enough. PHP (since you mention it in the next paragraph) will by default kill running scripts if a timeout value is reached. This timeout can be modified accordingly.

It doesn't sound plausible since php is loaded with an apache thread, which gets recycled every now and then, leaving the connection open on the mysql side but never used by apache agian. We don't do persistent connections at all with our sites and we don't notice a speed problem (mod_perl). PHP provides a mysql_pconnect() function which is supposed to do persistant connections according to the documentation. If you don't maintain persistent connections, you may want to take measures to ensure that each mysql connection attempt doesn't involve a DNS lookup (either put the hostname in /etc/hosts or use an IP address instead of a name) if your mysql server is not localhost.. -- Michael Bacarella | Netgraft Corporation | 545 Eighth Ave #401 Systems Analysis | New York, NY 10018 Technical Support | 212 946-1038 | 917 670-6982 Managed Services | [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?

any better way?
Subject: any better way? From: deco [EMAIL PROTECTED] === I have a bunch of data stored on a file and organized in messages... I got a message header and depending on the message type, i'll get a sequence of values which can be double, float, long, int, char, etc... Now i want to put this info in a mysql db, and i'm following this table structure (the whole thing is a bit more complicated, but this simple structure i think gives a nice picture of what i mean): TABLE types ( value_type_codeINT; value_type_descriptionTINYTEXT ); TABLE reads ( value_type_codeINT; read_valueTINYBLOB ); So, the thing is 'read_value' can be anything from a double, float, int, etc and so has a variable length. My solution was to have it like a TINYBLOB, where i may loose some space from the header (1 byte per record) but it's not very significative for me. But from here i'll have to be able to somehow make typecasts so i can make querys where i compare this blob values, and i don't quite know how to do this!! And i don't know if this is the best way to go, but i would surely be glad to hear from you all... The only other ways i thought of was to have this field like a double for all values, but it's not good. Other way was to have a different table for each value type, but that wouldn't be nice as i wan't to easily add new types as i go along!!

Re: VERY URGENT, possible bug. More on: What does this error message mean: InnoDB: Warning: difficult to find free blocks from the buffer pool..
I belive I have found a bug here, possibly. The last known commands to be run on the DB that are suspicious were a join between 2 tables. This is the info I got from the user who was workign on the DB: He was joining between keyword and billing select distinct(a.customerid) from cpcustomer.customerkeyword a left join cpbilling.billdetail b on a.customerid=b.customerid where b.customerid is null and active='y'; For some reason he hit ^c to exit (it didn't seem to be responding or somethign) He logged came back on to MySQL and ran: alter table add key bdetailcid (customerid); show create billdetail; It crashed (locked up) durning the last query mentioned above. I tried to shut down the server, but it wouldn't die so I ran the init-stop script a second time. It seems that the init start/stop script gets forceful on the second try. Started it back up, it took a _very_ long time recovering (InnoDB), then started in with the error message I first posted. Any ideas? I'm currently restoring from backups we'll see how it goes.

mysql database privilege problems...
Hi All, After working happily for months, my MySQL (v. 3.23.48-1) database has begun displaying the following problem: Whenever I log in as mysql root and try to change privileges for my database as follows: grant insert, select on MyDB_Name to MyExistingUserName; I get the error that the database mysql is read only. Is there an easy way to re-create the mysql permissions database and rebuild the permissions from scratch? I tried renaming the mysql db to mysql.bak and then restrating mysql, but it would not start until I renamed the file as it originally was. Any suggestions appreciated. __ Do You Yahoo!? Yahoo!

SQL Question...
Hello again, I am trying to set up a SQL statement using NOW(), what I am wanting to do is to use NOW() then do a search on any date less than 7 days. Before I get several e-mails asking why. I am trying to a news base database for the company intranet and I am wanting to only show newsitems that are 7 days or less. And I want NOW() to set today date and then go back as far as seven days. But I am not sure now to use less than in my statement with NOW(), or if it will work. | Chuck Payne | | Magi Design and Support | | www.magidesign.com | | [EMAIL PROTECTED] | BeOS, Macintosh 68K, Classic, and OS X, Linux Support.

Re: MySQL spanned over several systems
Try linux virtual server. You can Load Balance any port on a multitude of servers. Your MySQL Servers you would load balance would have to be read-only slaves though. We are currently running two linux virtual servers to load-balance same-port services on multiple servers with multiple Unix OSes. The Linux Virtual Servers are even clustering themselves for fail-over. -RG On Sat, 6 Apr 2002, Daniel Page wrote: Hi, I would like to try to implement a MySQL server that is spanned over several machines (a sort of database cluster) - as this is only a test, I am not too woried about the end OS, but I will probably use a Mandrake 8.1 or 8.2 Linux distribution. I have found in the manual information about running several servers on the same system, but nothing on running one (or several linked) servers that can run queries on a database distributed over several systems...

Re: VERY URGENT, possible bug. More on: What does this error message mean: InnoDB: Warning: difficult to find free blocks from the buffer pool..
Hi! MySQL AB and Innobase Oy entry-level support contract costs 3770 euros annually (3250 USD). For corporations with requirements for high availability we have more expensive telephone support options. These are extremely low priced compared against your costs for proprietary database products, and are low even when compared to rates charged by other open-source vendors.
