can you reference a column using the "." syntax? ie does users.first_name =users(first_name)?
when does one use users.first_name over users(first_name), and vice versa?
Well while using workbenches it does not allow me to use dot notation in replace for the other.
So if that answers your question then the answer would be no.
I assume it is because the dot notation is grabbing a value from the selected row in the query while the () is just defining what something is to be referenced on...
I am not entirely sure, but I will keep looking it up to find the answer!
EDIT: it looks like the dot notation is used when working directly with a row, while the () has been used while referencing a column.... Still a bit unsure sorry!
