Programming :: Insert Values Into A MySql Database?
Feb 9, 2010
I want to insert values into a MySql database. The following line works fine:1
Code:
mysql_query(connection, "INSERT INTO main (NumofShows , Title) VALUES('12', 'Home')");
but if the data to be inserted is from a string... like....
Code:
string NewTitle = "Monaco";
string NumofShows = "2";
How do i edit my sql statements so variables can be inserted into the Values ( ) , and it will be able to read the variables and then store it into the database.

I am writing a script to mine data from my game server logs which are going to mysql. My first question is syslog-ng is sticking $msg into one colum it self, $msg tends to be a long string here are a few examples:
cn name team frag death flags role host.
0 Maik CLA 2 0 0 normal *.70.233.118.
1 lizardncd RVSF -1 3 0 normal
[*.22.247.40] lizardncd fragged Maik.
And they are not always in the same format, How could I parse this data to do something useful, like creating a user stats page with frag counts and flag counts. Should I create a script that runs in a cronjob that parses this data to a new table maybe once a day. Even then the $msg string value is random and I am thinking in terms of awk.
Second. I would like to keep track of what ip's are using what nicknames. Kinda in the sense of and ip associated to a array of names that have been used on that ip address so I can keep track of users. How would this work logically with a mysql db, could a column allow multiple values, then loadable into an array, which then can add, remove, and store to mysql.

I have mysql installed successfully. I can insert rows into my table using phpMyAdmin. I can successful retrieve those rows in PHP with a select statement. However, I cannot insert or update rows from PHP. I get no error messages and everything appears to be working okay, just no results in mysql table.

I have created a database which stores students grades for different stages of a project. One of the stages of the project is the specification part. I have a simple bit of html code which is going to be used as the searching facility. I want the user to be able to enter their ID and then it will display only their results. At the moment, it is displaying the results for EVERY student because I cant seem to find the correct syntax for my statement.
Heres the HTML code
<html>
<head>
</head>
<body>
<body bgcolor="#6881bb">
<center>
[Code]....
At the moment when i click the button, no matter what I enter every students marks appear on the screen.
I think, but obviously dont know for sure because if i did i would know how to solve the problem, the code that i need to change is in green.

I've setup a CentOS apache web server, and loaded a site onto it. The site previously was functioning under windows xp (before I "stepped in") and wamp. What I did was copy the site in /var/www, reconfigure the httpd.conf (DocumentRoot /var/www/site, etc). Although when I try to open the webpage I get this error: Database Error: Unable to connect to the database:The MySQL adapter "mysql" is not available.

I'm getting duplicate entries in mysql database when submitting a new item from a form. I initially loaded the database via IMPORT function in phpMyAdmin. This is my input form:

However, I do need to return the input form in order to keep entering new items into the database.

I have a MySQL database running on my local server, which I currently access via laptop, desktop using HTML/PHP.I want to re-write in HTML5, I have gone through a couple of HTML5 tutorials but cannot figure out the database interface. The best match I can find is Server-Sent Events, is this the best way forward? What about writing to the database? I have found several suggestions using Web SQL database but I don't think this is suitable as my database is also accessed from Python code on the server.

I have set up a MySQL database which has only three fields for user-name, password and index number. But there is a LOT of data (thousands of columns) which would take too long to enter manually. I'm sure MySQL must have a file format whereby a single large file containing different data types can be successfully automatically imported and the various data elements distributed to their intended fields. Does anyone know which characters MySQL uses as field seperators for this formatting of data, or is there a program already written which can take raw data and organize it into a SQL compatible file?

I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:
Code:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I have a LAMP server. I know sql but I'm currently learning PHP.
Correct me if I'm wrong, but you're supposed to use PHP to insert/select data from the database, right? If so, SQL shouldn't need a port at all.
Apache uses port 80, but it's listening for connections. MySQL uses port 3306, but I've never logged into it from anywhere besides 127.0.0.1/localhost. I have mysqladmin installed and it demands that I give it an IP so I used localhost.
I'm not interested in doing anything remote, so can I block this port? When I say "block" I mean on the router, not locally through iptables. Obviously I have to foward port 80 because that's how people would connect to my server. But once they connect and send something, my server would interpret the data locally and send it back on port 80.

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.

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.

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);

My existing MySQL database is running on 11.1. I plan to do a fresh install of 11.3 in order to utilize the trimming feature for SSD drives. How should I install my MySQL database to the new version? Do I perform a backup then restore to the new install? Or can I just save the mysql db files to a cd and somehow attach it to the new install?
