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 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.

how to solve this and where is a problem
I spend much time on this issue but i'm unable to slove
please find out and how to solve this
I'm working a project with Yiiframwork and I have this table in my data base project
CREATE TABLE IF NOT EXISTS `tbl_annonce` (

I only use 'comment' because I found it in a tutorial for a yii framework project.
I have got the attribute 'idEntreprise' as FK in my DB but when I entred other 'idEntreprise' that does note exist in my table entreprise it was not problem, instead it must be a problem.
So I added 'identreprise' as Fk and that have this problem now.
Hope you understand my problem :/
can any one helep me plz !!
To define a foreign key on a column, it must fulfil some conditions.
Child and parent column must have same column definition by type,
signed.
Parent column must have an index defined on it.
Make sure that
The column tbl_entreprise.id is indexed.
The column definition idEntreprise tinyint(3) unsigned in tbl_annonce matches
with that of tbl_entreprise.id
Refer to: MySQL: Foregin Key Constaints
I have this table structure
CREATE TABLE IF NOT EXISTS `users` (

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 have got a problem with two tables:

The problem is, when i try to delete a record from address table I get the following error
DELETE
FROM addresses
WHERE per_id = 45
1451 - Cannot delete or update a parent row: a foreign key constraint fails (`site/events`, CONSTRAINT `adr_id` FOREIGN KEY (`adr_id`) REFERENCES `addresses` (`adr_id`) ON DELETE NO ACTION ON UPDATE NO ACTION) ;
The weird thing is that there is no record with the same per_id or adr_id in the events table.
So what's going on over here?
How Can I solve this? ;-)
/* I think it means "How can I solve this?" */
It may sound stupid, but are you absolutely sure there are no child rows?
Could you please run this:
SELECT e.*
FROM addresses a
JOIN events e
ON e.adr_id = a.adr_id
WHERE a.per_id = 45
