This query generates an error:
UPDATE sale
SET NumFacture='Null',
WHERE Code='22'
Where NumFacture is a foreign key in table sale so I can't update it with Null value. How can I do please!
Try without single quotes:
UPDATE sale
SET NumFacture=Null
WHERE Code='22'

How would one set a maximum call price? For example, limit the spend to $0.25 per call using Twilio.
If the calls cost exceeds this limit, then disconnect call.

I save some images in my database. Each images have a "tags" property.
I'm gonna show "search by tags" result to users, but there is a problem.For example, "IMAGE1" has "c#, programming, scripting" tags and I'm gonna show every images which have "programming" and "scripting" tags. So If I do that, "IMAGE1" will be duplicated.
So how can I prevent this duplicating ?!
Thanks !!
You can use DISTINCT operator of MySQL to retrieve non-duplicates
SELECT DISTINCT `imagename`
FROM `images`
WHERE (`tags` = 'programming') OR (`tags` = 'scripting')
The conditions for WHERE may be different depending on your PHP code.
