Re: Urgent Help needed: How to Correct this table so it doesn't have Composite Primary Key?

So normally we don't use char(36) ? and its primary purpose is not for
data /model integrity .. if I hear you right, AD.

Is the Model::save method the way we usually save by calling

function add()
{
}

are there additional steps ?

thanks, best regards.
