I have this table structure
CREATE TABLE IF NOT EXISTS `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(50) DEFAULT NULL,
`realname` varchar(50) NOT NULL,
`password` varchar(50) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`bos1` varchar(30) DEFAULT NULL,
`emailbos1` varchar(50) DEFAULT NULL,
`role` varchar(20) DEFAULT NULL,
`created` datetime DEFAULT NULL,
`modified` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=21 ;
I got an issue here :
Two persons (eg: username=steve, and balmer) has bos1 name (eg: bill)
When I login as steve and/or balmer I can see my own detail / data,
but when I login as bill, I want to show steve's and balmer's detail as well.
How do i suppose to do it ?
Thank you.

I am creating a database that will store 'graduate details'. I have been able to set the ID to auto increment, Unique and also my primary key that start from 1...
I also want to make the certificate number field unique and auto-increment value in an increasing order that will start from 00001.
Please any help on how to go about this will be very appreciated. Thank you.
This is the MYSQL code for the database below;
CREATE TABLE IF NOT EXISTS `graduates` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`f_name` varchar(25) NOT NULL,
`l_name` varchar(25) NOT NULL,
`gender` varchar(6) DEFAULT NULL,
`address` varchar(100) DEFAULT NULL,
`city` varchar(15) DEFAULT NULL,
`region` varchar(30) DEFAULT NULL,
`phone` varchar(15) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`certificate_number` int(50) NOT NULL AUTO_INCREMENT,
`programme` varchar(50) CHARACTER SET utf8mb4 NOT NULL,
`marks` int(10) NOT NULL,
`college_name` varchar(50) CHARACTER SET utf8mb4 NOT NULL,
`date_of_birth` date DEFAULT NULL,
`created_by` int(10) UNSIGNED NOT NULL DEFAULT 0,
`created_at` date DEFAULT NULL,
`updated_by` int(10) UNSIGNED NOT NULL DEFAULT 0,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `certificate_number` (`certificate_number`)
) ENGINE=InnoDB AUTO_INCREMENT=90 DEFAULT CHARSET=utf8;
after form submission, the data is stored in database. This is the query i already have:
CREATE TABLE IF NOT EXISTS `registered_users` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`first_name` varchar(255) NOT NULL,
`last_name` varchar(255) NOT NULL,
`gender` varchar(20) NOT NULL,
`date_birth` varchar(255) NOT NULL,
`address` varchar(255) NOT NULL,
`postal_code` varchar(255) NOT NULL,
`place` varchar(255) NOT NULL,
`school_name` varchar(255) NOT NULL,
`email` varchar(55) NOT NULL,
`tel` varchar(55) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
This is how i insert the data into the DB:
Now i want to insert a new row in the DB which can have only 2 values: "active" or "inactive" for each user. Default on "inactive". That should be inserted automatically for each user after submit. How can i do that?
When you create a table in a mysql db you can specify a default value for attributes. So if you want a boolean "active" / "inactive" flag you might want to try adding an active attribute to your table. See the added last column here:
CREATE TABLE IF NOT EXISTS `registered_users` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`first_name` varchar(255) NOT NULL,
`last_name` varchar(255) NOT NULL,
`gender` varchar(20) NOT NULL,
`date_birth` varchar(255) NOT NULL,
`address` varchar(255) NOT NULL,
`postal_code` varchar(255) NOT NULL,
`place` varchar(255) NOT NULL,
`school_name` varchar(255) NOT NULL,
`email` varchar(55) NOT NULL,
`tel` varchar(55) NOT NULL,
`active` BOOLEAN NOT NULL DEFAULT false,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

I keep on getting the below error message when I try to enter some important records I accentually deleted.
Duplicate entry 'EMIR2023 ' for key 'flightNo'
Is there a way in the phpMyAdmin environment I can disable the UNIQUE KEY then activate it when I am done with inserting the records?
Find below the structure of my table, I hope it helps

Looking forward to your reply :-)
Try unique_checks
SET unique_checks=0;
... import operation ...
SET unique_checks=1;
check reference
I have already running website and would like to integrate facebook connect with it.
My existing users table schema is :
CREATE TABLE `tbl_users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(32) NOT NULL,
`last_name` varchar(32) NOT NULL,
`email` varchar(96) NOT NULL ,
`password` varchar(120) NOT NULL,
`gender` varchar(5) DEFAULT NULL,
`about_me` text,
`image` varchar(120),
`status` int(1) NOT NULL,
`ip` varchar(15) NOT NULL DEFAULT '0',
`date_added` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
What are the changes required in above db table design?
Take a look at the following article:
http://net.tutsplus.com/tutorials/php/how-to-authenticate-your-users-with-facebook-connect/
Here is my USER table
CREATE TABLE IF NOT EXISTS `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(100) NOT NULL,
`expiry` varchar(6) NOT NULL,
`contact_id` int(11) NOT NULL,
`email` varchar(255) NOT NULL,
`password` varchar(100) NOT NULL,
`level` int(3) NOT NULL,
`active` tinyint(4) NOT NULL DEFAULT '1',
PRIMARY KEY (`id`,`email`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
And here is my contact_info table
CREATE TABLE IF NOT EXISTS `contact_info` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
`email_address` varchar(255) NOT NULL,
`company_name` varchar(255) NOT NULL,
`license_number` varchar(255) NOT NULL,
`phone` varchar(30) NOT NULL,
`fax` varchar(30) NOT NULL,
`mobile` varchar(30) NOT NULL,
`category` varchar(100) NOT NULL,
`country` varchar(20) NOT NULL,
`state` varchar(20) NOT NULL,
`city` varchar(100) NOT NULL,
`postcode` varchar(50) NOT NULL,
PRIMARY KEY (`id`,`email_address`),
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
The system uses username to login users. I want to modify it in such a way that it uses email for login. But there is no email_address in users table.
I have added foreign key - email in user table(which is email_address in contact_info).
How should I query database?
No, no, no, no no. Seriously, no. Don't make me come over there :-)
You're breaking third normal form by storing the email address twice.
The relationship need only be a short one, that of id. Assuming you're not guaranteeing the IDs will be identical in the two tables (i.e., my users.id isn't necessarily equal to my contact_info.id), just add a ci_id to the users table to act as a foreign key to the contact_info table.
Then the query to get a user's username and email will be something like:
select u.username, ci.email
from users u, contact_info ci
where u.username = 'paxdiablo'
and u.ci_id = ci.id;
