Hello, mysql,
After I create this table,and add foreign key tno to this table.
If I delete "tno" in "p_program_type" table,it would alarm that some data still in
"p_schedule".
How can I define the "p_schedule" or "p_program_type" table to make sure that while
delete the tno in p_program_type,the p_schedule table would delete the data matching
p_schedule table.
create table p_schedule(
sche_no int not null auto_increment,
cno int not null,
prog_no int not null,
start_time datetime,
end_time datetime,
index p_schedule_idx01 (cno),
foreign key (cno) references p_channel (cno),
index p_schedule_idx02 (prog_no),
primary key(sche_no),
foreign key (prog_no) references p_program( prog_no ),
foreign key (tno) references p_program_type(tno)
) TYPE=INNODB;
Best regards.
