Fedora :: Inserting To Escape Single Quote For Mysql Insert?
Oct 2, 2010
the project I'm working on requires parsing a text file with fields separated by the | char and using perl to insert/update a mysql database. Some of the fields are simple numeric and others are text fields. In some of the text fields I run into a problem creating a proper insert statement for the perl api to mysql if I don't escape the single quote (') char with a backslash (). I can take each text file and do a manual subsitutiton, but I would prefer to use the script that prepares the text file to do it for me. I've tried sed (ex: sed s/'/\'/g ) and it runs cleanly, but does nothing to accomplish my goal. I suppose I could write a function to read the file character by character and write it out that way, but it seems a waste.

I want to convert double quote to single quote in a text file. I tried escape characters however no success. Please find details as follows:
-sh-3.00$ sed 's/"/'/g test.txt
sed: -e expression #1, char 7: unterminated `s' command
-sh-3.00$ cat test.txt
"unix"
I want "unix" to be converted to 'unix'

I want to watch a number of processes in "D" status repeatedly with following command:Code:# watch -n 1 'top -b -n 1 | awk '{if ($8 == "D") {print; count++} } END {print count}''but it didn't work. I also tried with double quote. Can I use 'watch' command is this case?PS: I know 'while' and 'sleep' can do the same but it is dirty workaround.

I need sed to be able to search a string that includes both single quotes (') and double quotes ("). can anyone help me out, there has to be a way to do this.
So far I have tried:
But none of these work and I cannot think of how else to escape the sed quote inside of brackets.

I installed Ubuntu 11.04 and it refuses to show me a boot menu so I can select single user mode. When it does boot, it continues to cycle as X11 fails, but will not let me change into any of the consoles via control+shift+1-7 or control C or any command. X11/GDM continues to cycle as I hear my video card keep spinning up and down. In every version prior, after 3-4 fails it would give you a shell and say, ok it failed. how to boot into single user mode or escape out of this GDM/X11 fail cycle?

I've down loaded mysql database file and now I'm looking at adding it into a new dedicated server. Should I upload that sql file to the root folder I created for the domain and insert it with shh like that? If not where should I upload this mysql file to insert it to the new database. It's rather large so I have to use SHH Fir example if this is the code,
Code:
mysql -uUSERNAME -pPASSWORD DATABASENAME < MYDATABASE.sql
where is that actual location of MYDATABASE.sql

I have about 200k data entries in xml file. I wrote php script (using php-xml) to read xml file and insert into mysql. At first it went really quickly inserting, then after a while after inserting 100k entries, it slowed right down, just like it would not even doing anything. I have CentOs with 512M on VirtualBox running as server.

Making a low-pace instance of Conky on my server, running once a minute and without X-output. and then every minute it inserts a row in a MySQL table with some variables. Once it is in a MySQL database I can make a nice PHP-application showing some graphs and statistics or maybe even send a mail when the motherboard is catching fire or so

I would like to store JPG files in a mysql database table. I figured that using BLOB fields on the one hand and the 'load_file' command on the other would do the trick. Here is how I set up the table:
mysql> create table blobtable (id int(10) not null auto_increment,
fileName varchar(15) not null,
file longblob not null, primary key(id) );
Query OK, 0 rows affected (0.51 sec)
Then I tried to enter the data:
mysql> insert into blobtable(filename,file)values('pic',load_file('/var/www/temp/IMGP4764.JPG'));
Which got me the following error signal:
ERROR 1048 (23000): Column 'file' cannot be null
It seems to me that the file path to the JPG file (although correct) is the source of the problem, and is causing the load_file command not to work. My first attempt was with the JPG file in my PC's home directory. When that returned the same error message, I figured that maybe the file had to be in the PC's (server's) web area so I put it under the 'www' directory.

Trying to take a UK formatted date (30/12/2010) and insert it into Mysql (2010-12-30) is just not going to plan. I have a feeling I'm getting close, however it's just not working out.
Code:
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$unformatted_date = $_POST['date'];
$formatted_date = substr($unformatted_date,6,4) . "-" . substr($unformatted_date,3,2) . "-" . substr($unformatted_date,0,2);
[Code]....

Relational databases usually have their data over in /var/lib/something. Users are in /home (with data in /var/www). How can I apply a single total disk space quota across all of these independent software systems (file systems, RDBMS, etc.)?
P.S. There's a bet going on around me as to just how awesome SU is. Let's see what you've got.

I just installed F15 and although different, I like it a lot. One thing I don't like, however, is the default auto-completion of environment variables in the terminal. In F14 and older, if you type for instance
Code:
ls $HOME and hit TAB, auto-complete will list the contents of $HOME to search deeper, so to say. But in F15, the terminal automatically escapes the $ sign. If you do the same as above, you get
Code:
ls $HOME
instead of
Code:
ls /home/benny/
how to change the auto-complete settings of the terminal so that $'s are not escaped anymore?

recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.

I've been attempting to set up a LAMP for local web development, which meant installing mysql-server. But now have a problem when trying to run mysql, I get:-
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
When trying to downgrade mysql-server I saw that there are dependency problems between the various modules (but can't recall which). But whichever route I truied the results are always the same.
Thought about trying XAMPP but I note that even has it's problems, is there any way I can get a lamp set up on FC14, or must I give it up as a bad job.
Howver, just been trying to again to fix the problems with downgrading mysql and get:-
Error: Package: mysql-server-5.1.55-1.fc14.i686 (@updates)
Requires: mysql(x86-32) = 5.1.55-1.fc14
Removing: mysql-5.1.55-1.fc14.i686 (@updates)
mysql(x86-32) = 5.1.55-1.fc14
