I dont think you can do that with DRI , but one solution is :

xcues me..what is DRI.

i think i can use on delete set null...

thaks all for helping me...

ya.. that was usefull.

but i want to know the way to write it formally

is it true if i say that has_passed is transitivily depends on student_id and subjedt_id?

actually what i meant is this, you go through set of values to find a particular value inside that set is comparison,

and while comparing if you want to exchange two...

i appreciate ur modesty

it means i hv to delete this table and all the depending tables and and restart creating , in order to add on delete cascade option.

oh dear don think abt it

'cause user requirements change very rapidly

since i want only to show 't' or 'f' in upper case letters, i will use

select upper(flag)

from patient

...

thank u for ur replies..

and is there any way to combine access forms with sql?

thank you so much..
