Re: 2007 MySQL Community Survey - Got Ten Minutes to Spare?
Problems again with the survey design and functionality. Page 4 asks questions about Falcon, and to be honest I don't know anything about Falcon, but you've required answers to advance and only offered yes' and no' as choices. Without a Don't know choice as an option, your results will be totally skewed. I designed survey questionnaires in my past life as a psychologist, and this one is fatally flawed. I'm done. I won't try again. David Thanks for the input! Hopefully, I've fixed the problem. Please retry. It should have saved your previous answers. Thanks much! Jay J.R.

Inserting null values in mysql with PHP
Hello I have a table which contain a few numerical values. I set the default values to be NULL. When I insert values using phpMyAdmin, it sets the values to NULL correctly. But when I insert using a PHP script that I wrote it sets the values to 0.00or 0. In my script I do test if the values are empty and in case they are I set the variable to NULL. But that still doesn't help. Is that a mysql problem ? Thank you. -- -Mahmoud Badreddine http://www.spreadfirefox.com/

Re: Suse Linux (SLES10), Portuguese characters and dead keys in MySQL monitor in SSH sessions with Unicode (UTF-8)
Hi all, Here I am, following up to my own post - available below and at http://lists.mysql.com/mysql/208343 - with a solution (basically, a workaround). To summarize: I couldn't enter Portuguese accented characters in MySQL monitor (MySQL command line / console client), when I'm in a SSH (Secure Shell) Session, in a SUSE Linux Enterprise Server 10, configured to use Unicode (UTF-8 encoding). The Portuguese accented characters appeared well, in the same SSH session, for other shell (bash) commands and in Vim editing sessions (using the same Portuguese keyboard with accent keys that are dead keys). To make a long story short, the problem does NOT seem to be related with the SSH session, but seems to be related with the shell *user* that I use to login: 1 - If I log in to the shell of the Linux server with a regular user, either through a SSH session or directly in the local console (the one physically attached to the server) and I do a su to change to the root user, then the following happens: when I enter the mysql console (by entering the mysql command), the accented characters do NOT appear (typing ã - lowercase a with tilde accent - appears as a # - hash sign). 2 - If I log in to the shell of the Linux server directly with the root user, when I enter the mysql console (by entering the mysql command) all the accented characters appear correctly (this also happens either in a SSH session or by logging in directly in the local console). Like I said in my previous post, this server has the following MySQL version: 5.0.41-community MySQL Community Edition (GPL). I forgot to mention that I'm using bash shell - GNU bash, version 3.1.17(1)-release (i586-suse-linux) and that my readline version is 5.1-24.4 The bug is also happening in another server that's using version 5.0.45-community MySQL Community Edition (GPL). Did anyone else have this problem? If so, how did you solve it? Did you change everything from UTF-8 back to ISO-8859-1? *Or* do you enter directly as root, as I'm doing now (to work around this issue)? *Or* do you simply do NOT type accented characters directly in the MySQL Monitor (that is, the command line mysql client)? Thanks in advance for any info that you may give me! :) Best wishes, Ricardo Dias Marques newsgroup DOT posts AT gmail DOT com On 7/31/07, Ricardo Dias Marques [EMAIL PROTECTED] wrote: Hi all, First of all, sorry for the lengthy subject, but it serves to describe my problem: I'm having problems entering Portuguese accented characters (with a Portuguese keyboard) in MySQL monitor (MySQL command line / console client), when I'm in a SSH (Secure Shell) Session, in a Linux Server configured to use Unicode (UTF-8 encoding). I'm using dead keys - http://en.wikipedia.org/wiki/Dead_key - to enter the accented characters.

Not the rest of the 934 records... You are using ENCLOSED BY '' in your SQL, which I have had cause hassle with excel generated csv files. Basically, excel will only wrap field values in double quotes if the value contains the field delimiter. This caught me out, although I seem to remember I did get an error. Try removing the ENCLOSED BY anyway, it's optional. Another thing to watch for is column headers in your input file that may be triggering column constraints. You can get past this by using the IGNORE n LINES syntax in your command. I usually specify the table column names too - I have happily loaded up csv files from excel with something like the following: LOAD DATA LOCAL INFILE 'file.csv' INTO TABLE MyTable FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 LINES (column1,column2,column_etc); Hope this helps.

Re: Import file into MySQL Database..
I believe that excel files generally terminate lines with '\r\n' and if you use terminated by '\n' it will cause this behavior. so try it with lines terminated by '\r\n' or get TextPad or a similar editor that can save the file as unix platform that uses the same line terminators that MySQL expects by default and leave out the optional terminated by cj On 8/8/07, Jason Pruim [EMAIL PROTECTED] wrote: Okay, so I have been going crazy trying to figure this out...

Binary Log Incremental / Full Backups
I am new to MySQL administration, and must devise a backup plan, I have read the manual but still want to know if I am understanding and applying the principals correctly, please let me know if you have a better way, or if I am wrong somewhere, my main question is regardng the locking of the database while dumping, is it strictly neccessary (see [Confusion] block)? I am trying to devise a backup plan for MySQL ISAM Databases, I have chosen to use binary logs to enable incremental an incremental backup plan. I need to eliminate possibility of data being lost, and assure integrity of data, I will mainly be dealing with the former in this message. The Backup Plan: Preparation: 1. Enable binary logging on server 2. Prepare backup location (I was thinking SCP over the internet to a backup host, any faster/better soloutions?) 3. Write full and incremental script(s) 4. Set up cron jobs to run the incremetal and full backup scripts daily, and weekly respectivley 5. Run the Full backup script once [Full backup script actions] 1. Lock the database so it cannot change, 2. Backup the entire database via a dump, compress, transfer 3. Reset the logs (RESET MASTER, causing binlog index to be reset, ALL logs deleted and new log file created, thats ok, we have a full backup) 4. Unlock the database [/Full backup script] [Incremental backup script actions] 1. Flush logs 2. backup all logs except the last one via compress and transfer 3. purge all logs except the last one [/Incremental] [Schedule] Day 1: execute incremtal .. Day 7: execute incremtal execute full, binary log index is reset [/Schedule] Please tell me if this is the best correct way to do it, and if any of my following statements are incorrect/I have missed something: [Confusion] You need to lock the database when doing a full backup to maintain integrity of the logs, after the backup time becuase without locking: 1. If you flush logs, then dump, and a change occurs which is reflected in the dump, restoring the log to this backup will duplicate the change. 2. If you reset logs then dump, you have lost the information between your last backup and the dump if the dump fails 3. If you dump then reset, and data has changed in between the dump of a record and the new log, that change will be lost forever. 4. If you dump then flush (excuse the pun), restoring the log from before the dump to the dump could duplicate data [/Confusion] Whereas: If you lock the database, then dump, then reset logs and unlock, you have an exact mirror of the data, and a log file which contains changes after the dump was made Thanks.

Re: auto increment format
If you are going to implement real security, it shouldn't matter if someone nows the unique id of a record. You should be checking if they have the right to see that record. But regardless, there is an easy way to set random ids as your unique identifier. Setup 2 fields, one being the random number of string that you generate, the other being an auto_increment field. You primary key will be the combination of these field (random +autoincrement). The auto_increment field will almost always be 1 until there is a conflict with the random ids, in which case it will increment. The downside is that all your queries (joins too) will need to reference 2 fields instead of 1. On Aug 7, 2007, at 8:05 AM, shivendra wrote: Hi, I'm looking for some basic help.
