moi j'avais fait ca, et ca marche bien :
strreq10 = "create table OBSERVATIONS " & _
"(" & _
"observationid autoincrement, " & _
"ID char(8), " & _
"observation char(255), " & _
"observationtype integer, " & _
"constraint " & _
"pk_OBSERVATIONS primary ke(OBSERVATIONID), "& _
"CONSTRAINT " & _
"fk_student3 foreign key(ID) references STUDENTS (id) " & _
"on delete cascade" & _
" )"
