MYSQL :: System Tables?

MYSQL System Tables
I have to 2 questions:
1. I am very new to MySQL. I wonder what is the equivalent table for sysobjects in SQL server 2000.
2. I am trying to connect my hosted mysql db, it gave me mysql error number 2013. I dont know what is the problem.

Join Tables For An Email Alert System
I am creating an email alert system so when a new ad is posted within a certain metro area, emails will be sent out to those that have subscribed to that metro area's alert.

Users can subscribe to multiple metro areas. I want to send one email to each subscriber which contains all the alerts for multiple metro areas.

I can write a query just fine for returning all the ads that were posted the day before (emails sent out 3AM in the morning), see Code:

Can't Create The System/user MySQL Tables
I have mysql installed via rpm package, but when I check the data
dirs, the only table there is "test". The instructions say there
should be others, like users tables, and other such tables.

I stopped the server and ran mysql_install_db which is the command to
create these, I get the following excerpt:

linux:/usr/bin # mysql_install_db --user=mysql
Installing all prepared tables
050304 6:10:00 [Warning] Asked for 196608 thread stack, but got
126976
Fill help tables
050304 6:10:00 [Warning] Asked for 196608 thread stack, but got
126976
.....

But when I check, it doesn't seem to make these tables, only the test
table.

Is this normal? I thought the user table contains the login info, so
if there isn't one, how can I log in?

Best Way To Set Up Membership System
My site will have users that sign up and can then become part of multiple groups (think similar to Yahoo Groups or something like that). How would be the best way to set up the database/table structure so queries could be run to find both all the groups that a user is a member of and also get membership lists for each individual group?

Registration System
I have my database and HTML forms made. When I click submit to submit the registration it doesnt go to to the database it comes to a page with all of my database stuff on it. Can someone help? I have the page register.html made with the forms on it. When you click on submit its supposed to go to register.php which will send the info to the database. But is doesnt.

Privilege System
Is there a way to limit update access for a user to a single record? I have a database table that contains various information about people. That information is contained in a record for each person.

Is there a system log file which can be checked to see the histroy of triggers. I am trying to debug a trigger that is not executing when it should.

Rating System
i want to do a rating system like youtube's where it averages out the total ratings. i'd store each of the ratings per each row and have them seperated by comma's then in my code put them in to an array.

i also wanted to store the usernames of the voters in the database in the same fashion (without displaying them though) as above say instead of using cookies (as they can be deleted). would method this be feasible? or would this say overload the database and cause slow down?

Booking System
Hi, does anyone know of a site (tutorialised / open source) that offers a PHP-MySQL Online Booking System (similar to a Hotel Booking System)

Privilege System

System Variable
i am connected to the server and
i build some tables etc etc. everything is fine.

i run the command "show variables". it executes fine and shows me the values
of all the variables on the server. now if i try and change the value of the
variable tmpdir using the set command, it tells me unknown "error 1193:
system variable tmpdir". help needed here........

another point, the variable "tmpdir", points to the dir c:/windows/temp. i
put a text file in that dir and try to load some data from that file into a
table, and i get an error "file not found".

Ranking System
I've made a forum and i want to have a ranking system with it. I managed to display a postcount but i also want a few images to be displayed, like if you have made more then 50 posts, it displays 50.jpg or something, how can i accomplish this, in another way then just str_replace()ing all the number of posts?
And how do i display 2, like if you have 50 posts, 50.jpg and if you have 60 posts, 60.jpg.

System.OutOfMemoryException
sql 2 error: Exception of type 'System.OutOfMemoryException' was thrown.

this is the error I am getting using Mysql connect and Visual Studio.

My program is set on a loop and after the program has opened and closed around a million connections in my error logs i see this error about 80 or 90 times then it gives me a timeout error until I stop the loop. If i try to restart it it will continue to fail unless I restart the computer containing the database. Does anyone know what is causing this or how I can fix it?

Voting System
***********************
| game_id | discussion_id |
***********************

SELECT game_id, discussion_id, count( * ) FROM `games_voting` AS votes
GROUP BY votes.game_id, votes.discussion_id

using the above query to generate a count of votes grouped by game and then user who got the votes
right now it returns all the users that received votes for each game, i'd like to only receive the user with the top vote count

Scoring System
Im sure some of you have come across 'neave' games?

The scoring system is setup as below:
CREATE TABLE games_pacman (
name VARCHAR(20) PRIMARY KEY NOT NULL,
score INT(11) DEFAULT '0' NOT NULL,
ip VARCHAR(15)
);

CREATE TABLE games_banned_ip (
ip VARCHAR(15) PRIMARY KEY NOT NULL
);

Clearly, it is possible to ban ip addresses from using the score system.

But, can anyone tell me please if it is possible to set it up to ban certain names from being used?

System Configuration
I'm currently rebuilding my home system - a couple of linux boxes with Debian.
Although I don't have a high load on any of my systems, I am going to set up a separate box with my mail server and another for my web services. I'm wondering if there is an arguement for or against putting MySQL over on the mail box or even putting it on its own box?Assuming the arguement is for putting MySQL on a different box, are there any pitfalls, tips, tricks I should consider before starting this project?

Heavy Traffic System
I am developing a very heavy traffic site. It may happen that at same time (exactly same) two user will try to register with the same username. What will be the approach to prevent this situation. Which user will be able to register and which one will be denied? Do I need to use any locking facility? If so is it a wise decision to lock entire table?

Song Request System
I'm new to MySQL and have been racking my brains at this for hours, studying the MySQL documentation, etc, and have given up.

All I want is some form of PHP/MySQL integration on my website that allows visitors to Reuqest Songs, and my DJ's be able to view all the reuqests in a page.

It'd just involve adding values to a database (song name and song title) then getting a page to query them out and display them again.

Would someone be so kind to write me a very very basic script that will do what I require?

Standardized Naming System ?
is there a common naming system for db objects ?

Like:

1) Tables: mytable, tblmytable, tbl_mytable

2) Indices: idx_anindex

3) Columns: int_somenumber, date_lastupdate

4) id for the numerical primary key e.g. table customers.id
and then for referencing foreign keys
table addresses : addresses.customer_id or addresses.customer_fk

OK, I know I could name them the way I want but perhaps there is some
kind of common sense in this regard ?

System Variable Tx_isolation
The System Variable tx_isolation is used for what? What this actually means,

Development Server

System Variable Value
tx_isolation READ-COMMITTED

Production Server
trx_isolation REPEATABLE-READ

What will be the difference between these two thing?

System Requirements Of MySQL
I need minimum system requirements for installing MySQL server. This is for
service definition. Please provide me the info/link from where I can get the
info.

Recommended System Specs?
I was wondering if anybody could point me to any documentation or could suggest some info on a small MySQL server that I'm setting up.

This will be running Windows and IIS (i know, i know) and be for a maximum of 20 users; nothing special.

Any suggestions for processor and RAM or things to look out for? It will be running the MySQL Community Server 5.0.

Client Login System
I am working on making a client login system. I would like client's to be able to login on my site and just basically see their individual invoices, pay with Paypal, see site progress, that kind of thing. I have some ideas as how to do it, but I was wondering if anyone had some suggestions?

ASP And MySQL Membership System?
I'm trying to set up an ASP and mySQL (or Microsoft Access if absolutely necessary).

It needs to allow users to register, certain pages to be "members only," and it needs to have an email password reminder system.

I have a good deal of beginning experience with coding (I've studied the beginnings of C++, VB, javascript, CSS, and have sort of worked with PHP on a discussion board).

Anyone have a GOOD and somewhat UPDATED and RECENT tutorial?

External System Call
Is it possible to trigger external system calls from mysql db? I want to start an external script after a certain value has been set in DB?

Example

I write a message -> it goes into a db with al the messages posted for the day -> the next day al the messages will be posted in another db for the frontpage at a given time.

So you get msg 1 at 12.00 at the fp
msg2 at 14.00 at 14.00 at the fp
etc.

I am trying to develop a simple request tracker system. I am just wondering if php/mysql is a good idea. Can you point me to a sample on the web?

Disable Privilege System
If I set skip-networking, what is the security risk if I also skip-grant-tables? Is there any performance benefit that might justify leaving the privilege system disabled?

This is a dedicated database that runs on the same machine that hosts the application that it supports.

MySQLdump Crippling System
I'm trying to backup a 3 GB MySQL database on a production web server. I started working on this server the other day and it is quite old and is running ancient packaged in FreeBSD, etc.

I also had a look at the backup system and it didn't appear to be working as intended. Can someone with experience just verify for me that I can use mysqldump --flush-logs --all-databases > backup.sql in order to backup all of my databases into that file? And is there a better way of doing this? It seems to take up a lot of system resources on this server.

Operating System Error
I have inherited some linux servers running mysql at my company from a prior administrator and have ran into a few problems.

For some reason my mysql server daemon stopped running unexpectedly. I attempted to start the daemon with the mysqld command a recieved the following error.

070917 10:22:33 InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
InnoDB: File name ./ibdata1
InnoDB: File operation call: 'open'.
InnoDB: Cannot continue operation.

I also found another command to start the daemon in some sort of safe mode and it shows the followin error:

Starting mysqld daemon with databases from /var/lib/mysql
STOPPING server from pid file /var/lib/mysql/mysqlsrvr.pid
070917 10:20:46 mysqld ended

I have checked permissions on pretty much every directory I could think of but still I get this error. Can someone please help?

Topic Rating System
I have a rating system on a forum I'm building. Users can rate a topic either good or bad. For each Good rating, one point is added to the topic's score. For every Bad rating, one point is subtracted to the topic's score.

Each time a rating is made, several things are inputted into a MySQL table called ratings

rating_id
rating_date
rating_username
rating_topic
rating_value

What I want to be able to do is query this table to grab the highest rated topics and lowest rated topics in a given time period. My MySQL knowledge is pretty limited right now.

School Mailing System
I am developing a bulk email system to send messages to parents of the
children in the school I work at, using php and mysql. The database
holding the parents' email addresses and what yeargroup their child is in.

I would appreciate any input on the best method of tracking a pupil's
yeargroup as they move up through the school. For example, I would like a
field in each record to indicate what yeargroup they are currently a part
of and when the next academic year comes around there wouldn't be any
needs for an update.

User Address System
I'm working on a user based data system. I need to store a user's addresses which could be 0 or more.

However the addresses could be domestic or foreign. I can tackle creating a multiple domestic address storage solution very easily. However, modifying this to encapsulate both a domestic and foriegn addressing system is boggling my mind. Mainly because foreign addresses don't all share the same format and ordering. Some use county, some don't. Some list a village, some don't, etc....

I'm looking for anything or anyone to provide me with some guidance and/or support to help development the foreign addressing system. I can modify it myself to integrate the domestic addresses.

Mysql System Administration..
if it is possible in mysql to change such a factory settings like to increase or limit the maximum connection, increase the maximum storage for mysql in the system. and one more thing if we are in mysql environment is it possible to view how many queries per second mysql i already have...
by the way the only thing i know is when in mysql..
mysql>s; ->shows or get status information from the server.
any advanced mysql administration information about this?

Modified Bug System"
i'd guess the bug report system http://bugs.mysql.com is from bugs.php.net, but modified
anyone know where can i get this version?

Simple Rating System
I want to create a very simple rating system. User chooses from a drop down menu 1 to 10 and the result is shown next it.
The catch is i don't know about PHP or MySql. But i've been at this for several hours and i'm a fast learner.

If any of you have heard of it i am trying to use the free RateIt! script availble from http://www.skintech.org/rateit/install.php

But it keeps going on about creating a MySql table. a) i don't know how and b) i don't even konw why, what the table is used for. perhaps if i knew this i could understand it better.

System Tables?

Is there documentation on the system tables? I couldn't seem to find anything when I did a search on system tables. I know about the information schema, but I want to know about the tables the information schema uses to build the views it contains.
