HTML in MySQL?
Hi guys, I'm fairly new to MySQL and I've searched for about a week looking for an answer to this... I'm trying to design a Database that would hold HTML sites in the DB itself and use PHP to call for the HTML file - which would be populated with Content from another table in MySQL. I was told I could put HTML into MySQL... so my main question would be: is this possible?, is this a BAD thing? but most of all... would this be resource intensive? Thanks for any answers! I hope I'm using this list correctly - I did search Google and I've been reading an MySQL Manual for over a week now trying to get it down 110%! Thanks, Clint

RE: HTML in MySQL?
Hi Clint, Another possibility is to actually run the mysql client with a --html option and let mysql do the work for you eg : prompt $ echo SELECT some_stuff FROM table | mysql -u xyz -pxxx --html This generates a block of html for a table with the data encapsulated within, then it is just a matter of capturing the output and putting it in the html stream. You can also generate xml the same way.

So far I have found this article to help: http://www.databasejournal.com/features/mysql/article.php/10897_1402311_3 But it still leaves me with a ton of questions. For starters, and don't laugh, I just installed mysql and let it run, started adding sites to it and such. The machine has 1 gig of ram in in, but at times, I could ask it were a little snappier. It is a 1.2Ghz machine. First thing I did last night was to try to get a hnalde on this.

I set up a cron job to run the following: show variables like 'table_cache' show status like 'open%_tables' I have been running this once a minute for a day now, how long should I run it to get an idea of what I need to change to better suit my servers load usage?

I am really looking for some pretty detailed docs on exactly what I can do in my.cnf to make this work out better. Thanks again, and if there are any questions that would help me get a better answer, please let me know. Try to find a book called High Performance MySQL from Derek J. Balling Jeremy Zawodny (the guy from Yahoo). It's an interesting and useful book which skips all the basic stuff and gets you into performance tuning.

Re: Delayed UPDATE execution?
Hello. So now my question... is it possible that MySQL didn't execute that first UPDATE query on that first page until after the rest of the process completed? ... - Every page has UPDATEs, INSERTs, or DELETE commands so I'm wondering whether the There is no 'UPDATE DELAYED' or similar. Possible cause of the problem is that your application uses REPLACE DELAYED instead of UPDATE, but you haven't meant this statement. Are you sure that this issue doesn't come from browser's (proxy) cache? - I did notice that the website was very sluggish during that time and even unresponsive. Would that affect the order of query execution? If you don't use DELAYED statements the order of the query execution from one connection shouldn't change. Hi all, I'll give you a little background so that my question is put into context. I've already posted this question to my local programmers message group and they said to post it here. So, here it goes: I have a phone order system that I wrote in PHP. It has a series of pages starting with a customer select and edit screen. After the billing and shipping information is verified and modified, the employee continues through the shopping process until the final checkout page where the order is stored. One of the employees contacted me and said that she was placing a new order, found an existing customer, modified the shipping address on that first page and then entered the rest of the order. The order does not reflect the change in shipping address, BUT looking at the account now shows the correctly changed shipping address. She says that she did not go back after the order was entered to change the account. So now my question... is it possible that MySQL didn't execute that first UPDATE query on that first page until after the rest of the process completed? - The customer page is a basic form that posts the information to itself with a simple UPDATE command and then goes to the next page. - Every page has UPDATEs, INSERTs, or DELETE commands so I'm wondering whether the commands are queued and that first update was delayed for some reason? - There are no session variables, or hidden form fields, that would cause a problem with hitting BACK or whatnot in the process. - I did notice that the website was very sluggish during that time and even unresponsive. Would that affect the order of query execution? Any ideas? Thanks in advance for your help!

Re: Delayed UPDATE execution?
Okay, I asked the web host guys and this is what they said: Hi Jenifer, we only use single instances of MySQL so the master/slave replication issue would not be possible. As far as I know, the only way a delayed update could occur would be if you had multiple updates queued behind a slow update or any slow query that has left the table locked. But if that were to occur, I don't think the user of your application would have been able to advance to the next page of the site since the queries from them hitting submit would have been hung. Unless you are using timeout values in your php so after a delay, it gives up and lets the person move on anyway, and then ultimately the final page is reached while that first update finally went through. That's what I had thought that the user would have been stuck at that first page. I'm trying to figure out how a cache could affect it. The values are taken from the $_POST variable and inserted into the table that way. When I looked at the order and customer pages, it was after she had done everything, and I saw the incorrect order shipping address and a correct account address. I haven't looked at this client's account before as the company has 40,000+ customers in their database. (a big cudo for MySQL for handling them so well!) I think I'll just give up on this one and readdress it if it happens again. It will probably eat at me for awhile, though, not knowing the answer. lol! Jenifer - Original Message - How is your MySQL installation set up? At my company, we have a master server and several slaves replicating off that master. All inserts/updates go to the master, and all selects go to the slaves. We have had some instances where we insert or modify a record in the master, and request that information from a slave before the replication has had a chance to complete, so we get old data.

Help with SQL Command

The data will be in the form of a tab delimited text file that will generated several times a day with different data.

I know the SQL command works fine. I'm using it on another database, but I am manually entering it in. On this project, I won't have that kind of time to manually type it or open the MySQL Query Brower and re-run the command. Any help would be greatly appreciated, but remember I am still real new to this. Thanks, eric
RE: HTML in MySQL?
If you use textarea field of a form, it produces null characters (\n) in the end of every string. I recommed to replace them with br tags before writing into the database. It'll help to avoid output problems. Use preg_replace(); for it. Be careful here Vladimir, the (\n) are not 'null' characters; but newline characters. And i would highly recommend *not* replacing them with br tags as you write them into the database. This is asking for trouble on so many levels.

Re: `gmake test` probs Solaris9 for M. 4.1.4.
Hugh, I get the same thing on Mac OS X 10.3.9. My thinking was that rather than replying with an unhelpful Me too, I would do some digging and then reply with what I found. I realize now that left you hanging (sorry), so I'll report what I've found so far. The test suite is broken.

So I changed it there. I changed it to give me the alternative port and directory so I don't munge things for people using V3.x, used for teaching. [Besides, I'd have to mess with autoconf to fix configure properly, as it is setup by that, and I'm not so fluent in autoconf as I'd wish, plus it seems silly to mod the autoconf stuff for something so parochial as port + directory.] Maybe there's a better place altogether to define this stuff?

How to save graphs in a table?
I would like to save graphs in a mysql data base. The table definition I have set up is: CREATE TABLE `GRAPHS` ( `graphid` int(11) NOT NULL auto_increment, `graphic` blob, `f_time_stamp` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP, PRIMARY KEY (`graphid`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 And I have allocated the user account the file privilege. The sql I am trying to use is: load data infile 'filename.png' into table GRAPHS (graphic); What happens is that the takes the file and breaks it up into lines and loads each line as a row, thus storing it over many columns. How can I get it to store the file in the 'graphic' blob with one 'graphid'. Thanks in advance.

Re: row level replication in 5.1
Kenji HIROHAMA [EMAIL PROTECTED] wrote on 09/08/2005 08:54:58 PM: Hi, Does somebody point me out where I should refer to understand what is row level replication implemented in 5.1? I should have read the source comments in the source tree, but the bk port is closed at my environment. Regards, Kenji I couldn't find it in the manual either but I can try to explain the concept and how it is different than the currently used replication process, statement level replication (SLR). If you know how replication currently works in MySQL, you understand that each SQL statement that makes a change to data (INSERT, UPDATE, or DELETE) plus several others that modify database structures can be recorded to what is called the binary log or binlog for short. I say it as can be written because you can apply some filters so that you only binlog the events that apply to certain tables or datbases that you are interested in duplicating at the slave server. Events are only written to the binlog as each transaction is committed, transactions that fail or are rolled back are not logged in the binlog. Each slave server reads the binlog from the master, copies it to a local drive, then processes each command in sequence attempting to duplicate the results that occurred on the Master when it executed the same statement. Because the slave needs to execute each command within the exact same set of enviromental settings (what time did the original command occur on the MASTER, within the context of which database, using which user account, etc.) there are certain problems with duplicating the effects of particular commands correctly on the slave servers. Row level replication (RLR) gets around those environmentally-based pitfalls by actually duplicating each change, row by row, from master to slave. For statements that change many rows of data, RLR will need a lot of bandwidth because every change will replicate row-by-row from the master to the slave. (I don't remember reading if they are optimizing the difference stream by implementing field-level replication or not). This keeps the slave database in perfect coordination with the master (after some transfer and processing lag) because stored procedures and other functions that rely on system- and user-level environmental settings (like time zones) are not executed on the slave but only on the master.

Re: Total newb at performance tuning mysql
One of our engineers first installed MySQL on one of our Sun boxes which was doing nothing more than MySQL... It seems we also put it on the server and turned it on... it behaved very badly. Essentially when we started to investigate MySQL and find out if we could use it we discovered that our Sun box with four processors and 4Gbytes of ram was running MySQL in 64M of memory... it's an easy mistake to make, and the lesson here is that out of the box (as it were) MySQL settings are a little on the low side for performance... but work well for a shared environment where you may have web server, mail server and more all running on the same box. If you want MySQL to sing... you are going to have to do a lot of tuning. On the table_cache issue... We have about 40 tables per database, and some of our servers have 30 databases. Our servers have as many as 500 connections... one server at random which has an uptime of 60 days shows: mysql1 (none): show status like 'open%_tables'; +---+---+ | Variable_name | Value | +---+---+ | Open_tables | 2748 | | Opened_tables | 3288 | +---+---+ 2 rows in set (0.01 sec) mysql1 (none): show variables like 'table_cache'; +---+---+ | Variable_name | Value | +---+---+ | table_cache | 4096 | +---+---+ 1 row in set (0.01 sec) So we have a table cache value, but it's clearly on the high side and could be lower. Yours at 64 is on the low side. While I won't ignore table cache as being important, there are many many performance tuning things that need to get done to have an impact on the server. Firstly (knowing the type of things you are doing) InnoDB will likely be a far better choice for most of your tables than the default database engine, myisam. You need to tune the machine to run InnoDB, and then convert your data to InnoDB. If you are using MySQL 4.1 (which I can't remember) I would advise using innodb_file_per_table. If you are looking at upgrading to 4.1 I'd do that first before switching to innodb_file_per_table... it's a little hard to claim back the shared table space after the fact. If not 4.1 then go with InnoDB and build a big enough shared table space file set to hold all your data with room to spare. We typically build it with 20 2Gbyte files... for 40Gbytes of InnoDB table space. Decide how much memory you have to run MySQL... i the server does only MySQL, this is easy... if it's also a web server running Apache and so on, then you have to decide the mix. Assuming MySQL only give InnoDB 80% of the server's total memory, up to certain limits with 32 bit operating systems and the like... For OS X we found these are pretty much the magic numbers for max values if you have more than 2Gbytes of ram but can't handle 64 bit: innodb_buffer_pool_size=1850M innodb_additional_mem_pool_size=256M innodb_log_files_in_group=2 innodb_log_file_size=250M innodb_log_buffer_size=20M innodb_thread_concurrency=16 innodb_flush_log_at_trx_commit=0 innodb_lock_wait_timeout=30 Once you convert everything to InnoDB the regular MySQL buffers have less importance, but should still have some values. InnoDB or not the query_cache is a good thing, but don't set it too high... We are at 128Mbytes and that's a little higher than we need... it appears we could live in under 64Mbytes, and our query cache handles about 25% of our queries... properly set it's a good thing. So... most likely switching to InnoDB will improve performance... Managing all your memory settings and caches so that the ones that matter have values that will help will make a great deal of difference... of course to do this you'll need to make a my.cnf file and install it where MySQL will look for it. Also important for tuning is watching the slow queries, finding out if there are moe things you can do with indexes, or if there are other ways to optimize the queries. Turn on the slow query log... leave it set to the default 10 seconds... find out what queries are running longer than 10 seconds and figure out how to optimize them... changing indexes, changing the query etc... Once you have worked that out and your slow query log gets few hits, reduce it to 5 seconds and work through those queries... again reduce it further as you work out the performance issues and you'll find that you are streaming along. There's a lot more that can be done with specific memory settings and so on... but I think I've given you a handful of things to get started on, and you can come back for more when you have made some headway on this part.

Re: HTML in MySQL?
Hello! Be careful here Vladimir, the (\n) are not 'null' characters; but newline characters. Agree, I was wrong. And i would highly recommend *not* replacing them with br tags as you write them into the database. This is asking for trouble on so many levels. The database will cope with carriage returns and newlines just like any other character, so will have no problems. HTML is just string; treat it as such and don't give it anymore credit than that and you'll be fine. If you need to output a HTML string (not in a textarea field), you'll need to replace \n with br. That is why, I think that it is better to replace it before saving (You will not need to replace \n during the output process. It will save you some lines of code, and add productivity.). Of course, you need to be sure that your program will make HTML output more often, than any other type of output. -- Удачи! Владимир Please, avoid sending me Word or PowerPoint attachments.

Tomita If you look at the output from mysqldump, you will realize that it is just a series of SQL statements. Execute them with your command line client just as you would any other SQL script file. mysql database -u username -p dumpfile.txt or use the source or . commands if you are already in the CLI mysqlsource dumpfile.txt Where you will run into problems is if you didn't specify a max_packet_length WHEN YOU MADE THE DUMP. That option tells mysqldump just how long the longest single statement can be. If you try to run a dump file that contains a statement that exceeds the max_packet_length setting on your server, it will fail silently (server gone away). If you failed to dump with a maximum set, your options are to increase the MAX_PACKET_LENGTH on the server to accept the longest single statement in your dump file or to edit your dump by hand and break your long statements into shorter ones or both.

Simple Count Query
I know this has to be a simple query but its really kickin' my butt. I have the table below where fld1 is the year, fld2 is a number, fld 3 is a subnumber, and fld4 is the user. I need to know the count of all the records for user am without the sub number getting in the way. For example, the first record for user am shows in the 3rd year number 1 with two sub records was for user am . That needs to be counted as one item. So when all the items are counted I should have a total of 5 items for user am and not 17 like you'd normally get Any thoughts? thanks +--+--+--+--+ | fld1 | fld2 | fld3 | fld4 | +--+--+--+--+ | 3 | 1 | a | am | | 3 | 1 | b | am | | 3 | 2 | a | am | | 3 | 3 | a | pm | | 3 | 3 | b | pm | | 3 | 3 | c | pm | | 4 | 1 | a | pm | | 4 | 2 | a | pm | | 4 | 3 | a | am | | 4 | 3 | b | am | | 4 | 3 | c | am | | 4 | 3 | d | am | | 4 | 3 | e | am | | 4 | 3 | f | am | | 4 | 4 | a | am | | 4 | 4 | b | am | | 5 | 1 | a | pm | | 5 | 1 | b | pm | | 5 | 1 | c | pm | | 5 | 1 | d | pm | | 5 | 1 | e | pm | | 5 | 2 | a | am | | 5 | 2 | b | am | | 5 | 2 | c | am | | 5 | 2 | d | am | | 5 | 2 | e | am | | 5 | 2 | f | am | +--+--+--+--+ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Simple Count Query
Oops, that should be: select count(distinct fld1, fld2) from yourtable where fld4 = 'am'; That version of the query is tested and works with your data; it returns the fact that there are 5 combinations of fld1 and fld2 for all the rows where fld4 is 'am'.

Timezone query similiar to pgsql
Hi List, Does MySQL have something similiar to SELECT TIMESTAMP '2001-02-16 20:38:40' AT TIME ZONE 'Canada/Pacific'; I need to handle the timestamp in the database. Previous posts and some googling suggests it should be in the PHP layer which is not an option for me. My users come from various timezones, and so I plan to store everything in GMT (server time) and select the time based on their timezone preference which is stored in a user preference table. Suggestions always welcome :) Thanks Terence -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
