hi all,
i have just gone through the discrimininator and implmented table per class model of inheritance. here i have used only one column as discrimininator.
but can we use discriminator on two diffrent columns??

i got situation like this. i have two columns as follows

col1 --- col2

fax --- in
fax --- out
scan --- done
scan --- notdone

i have to diffrentiate rows basing on these two columns.
so here i have to use col1 and col2 as descriminators.
how can i do this??

ANY Idea??

You can register at most one column element-attribute to a discriminator but you can combine two columns using the power of formula.
