[PHP-DB] Problem with MySQL4.0.1 speed, cpu- and memory-usage
Hello, in order to be able to use the replication features of MySQL we recently gave version 4.0.1alpha a try, since these features are reportedly more reliable in this version - although it is still alpha. Unfortunately the disadvantages - at least on our machines - don't seem to make up for the advantages: we experienced a very high server load combined with higher memory-usage than usual, the average speed dropped to a level the tested databases became almost unusable. Let me explain our setup: we're running a site-internal messaging system that handles approx. 110.000 messages per day. The databases consists of a header and a content table, the first one being a fixed-length MyISAM-table with almost 40.000.000 records, the second one is a dynamic-length MyISAM-table with some 20.000.000 records. We don't use fancy stuff like InnoDB but only very basic SELECT (on indexed columns) and INSERT statements, not even JOINs. The whole thing runs on a 850MHz dual-pentium with 4GB memory under Linux 2.4.17 and RAID1. Until now we used MySQL 3.23.32 which in our tests remains the fastest version so far, all following versions (including 3.23.47 and 4.0.1alpha) remarkably dropped in speed. Now finally to my question: is there a way to speed up 4.0.1alpha (or any other version with reliable replication), maybe a different OS (BSD is reported to be more performant but we have no experience with that so far) could help? Are there any fine-tunings in the ./configure that may have a positive effect (we didn't notice big changes in speed and memory usage when playing with these options)? Usually we would just stick with 3.23.32 but, as mentioned above, we need the slightly more advanced and reliable replication features of its successors in order to be able to distribute read accesses to several slaves while the master does all the writing stuff.

RE: [PHP-DB] Pictures in MySQL database
Agreed, i think you'll find aan easy way of doing this is to name each image after the primary key to your table (ie 1.jpg, 2.jpg, 3.jpg etc if the primary key is an autonumber. and store them all in a certain file, then when you fetch the record from the table, you can run a simple check to see if there is an image corresponding to the record number in that file, and if so, display it. (if not, you can then use a default image, or a message saying no image. much easier than putting the binary stuff into a database! -Original Message- From: Miles Thompson [mailto:[EMAIL PROTECTED]] Sent: 24 January 2002 14:04 To: [EMAIL PROTECTED] Subject: Re: [PHP-DB] Pictures in MySQL database Re the PLS.

The only column that I would like to extract a value from is the password field (this is the key as well). I do not have an AUTO_INCREMENT field. Although, I see how adding that field could be of use by using it with the SELECT MAX() as you mentioned. The last record is whatever the last record was inserted using INSERT INTO. To give you the overall picture of what I am trying to accomplish: 1) I am opening up a db table and searching for the password of the last record in the table 2) I then open a flat file and search for that password and grab the next record after that (as records are appended to the end of the flat file) and any other subsequent records added to the flat file 3) Write those new records to the db table In this scenario, the last record would be the last record from the flat file added to the db table. Another suggestion from [EMAIL PROTECTED] was to: Select your password field, and whatever other fields you need to Use -mysql_num_rows() to capture the number of rows returned -mysql_data_seek() to position pointer on last row (remember indexing starts at 0) -mysql_fetch_row() or mysql_fetch_array(), your choice, to return the data. This is done with one select statement, however all the passwords from the table have to be loaded into array (perhaps not the most efficient way? But better than what I had come up with.). I do generally find that the more brief I am in describing an issue, the more likely I am to get a reply. Then details can be given if needed, in further correspondences.

So far all you have informed us is that the table has one column, which contains a bunch of passwords (I also suggest that this is not really the case and there'll at least be some sort of userId field - but you haven't bothered to tell me/us that) The concept of last in relational terminology is ambiguous. Do you mean last entered, or do you mean the row with the field containing the highest value in the column - for example. Some people are used to the idea that there is also some 'phantom' rowId that counts/labels each row. In other file systems this might have been the case, but the physically last record in an RDBMS table-file may not conform to either of the last definitions mentioned above. There is no such 'highest' in an RDBMS unless you put it there - as mentioned by another correspondent, it's a good idea to use some sort of 'id' field in every table. This can be generated for you with the AUTO_INCREMENT feature.

Re: [PHP-DB] dynamic sql
Have you tried it? I've done this sort of thing before, and it works just fine. By the time the query string is executed, the variables have been interpreted. So, if $colName = id, and $id = 12, then your query variable looks something like select * from myTable where $colName = $id. By the time you get to executing the query, it's been interpolated (?) to select * from myTable where id = 12. Michael K. Dolan Jr. wrote: Is it possible to do a sort of dynamic sql.

[PHP-DB] dynamic sql
Rich, thanks. I got the dynamic sql to work (i had a syntax problem), now my problem is what's the most efficient way to loop it through all the form fields that are passed to the processor? This is my current sql statement which handles 1 field: $sql_update = UPDATE md_users SET .$formName. = '$formValue' WHERE user_id = $user_id; How can I loop this through all the form fields? efficiently? I'm thinking of 2 scenarios, 1. loop and create an update and execute statement for each variable, but that has to be inefficient. 2. concantinate all the fields and then enter the names values where I have .$formName and $formValue - I don't know how to access an array of the posted values in php. I can do it in ASP with a request array, but I'm stuck on the PHP equivalent. If anyone can help, I'd appreciate it. Thanks, Mike
Re: [PHP-DB] problem with LOAD DATA INFILE for date format
There may be a better way, but in migrating from Filemaker to MySQL, I encountered similar problems. My solution was to pass the data through Excel and use that to convert the dates into the required format (CTRL-1, Custom, -mm-dd). Of course, you ned to watch out for those nasty ' ' ' that Excel puts around any cell containing a comma. So you might need to filter the output from excel in a text editor too but if its a one-off, its worth it. george - Original Message - From: Hendra [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, January 25, 2002 5:09 AM Subject: [PHP-DB] problem with LOAD DATA INFILE for date format Hi, I have a sample data like below in text file (policy.txt). PolicyNo,DateOfBirth,PaidToDate 0003573607, 9/25/1973, 8/27/2001 708802,11/26/1959, 5/25/1998 0002776507, 3/19/1973,11/18/1999 0002776703, 3/13/1969,11/18/1999 Policy table structure: +---+-+ | Field | Type| +---+-+ | PolicyNumber | char(10)| | DateOfBirth | date| | PaidToDate| date| +---+-+ When I do: LOAD DATA INFILE policy.txt INTO TABLE Policy FIELDS TERMINATED BY ',' ENCLOSED BY '' LINES TERMINATED BY '\n' IGNORE 1 LINES; All data in field DateOfBirth PaidToDate become -00-00 I notice this is because mysql only accept date format in -mm-dd. However, in my text file, the date format is in mm/dd/ format. Any idea? Thanks in advance.
