See there are child records available in the User_Organization table. and u have the relationship with the User table. So naturally when you delete a row in the User table which is having the reference value in the User_Organization table it won't allow.

that is why u get this error.

Rgrd,

Hi iyerganapas,

Why it won't allow me to delete?

Correct me if I'm wrong.

I have UserID=133 in [User].

In [User_Organization] I have UserID=133 OrgID=234.

I have ON DELETE CASCADE to [User_Organization].

Why it cannot delete UserID 133 in both tables?

i SEE WHERE YOU HAVE ON UPDATE CASCADE. BUT YOUR SCRIPT DOES NOT INCLUDE ON DELETE CASCADE.

look your organisation table does not have the cluase on delete cascade. that is why u get the error when u try to delete the master record.

Hi, deleting a row in User Table will leave any row using that UserID in organization_User Orphan ,you are violating Referential Integrity.The only way to avoid the error is to delete the row in Organization_User first and then the the one in User table.

Regards.

Thank you all!

It was my mistake.

Instead of having "ON DELETE CASCADE"

I selected "ON UPDATE CASCADE"

and didn't take care of the children in [User_Organization].

Sorry!

But you helped me to realize what I'm doing wrong.

Thank you very much for your help, guys!
