Operand type clash: int is incompatible with date + The INSERT statement conflicted with the FOREIGN KEY constraint

create table pilot (
emp_num int,
pl_license varchar (3),
pl_ratings varchar (30),
pl_med_type int,
pl_med_date date,
pl_pt135_date date,
constraint PK_pilot primary key (emp_num)
)

insert into pilot(emp_num,pl_license,pl_ratings,pl_med_type,pl_med_date,pl_pt135_date)
values (101,'ATP','SEL/MEL/instr/CFII',1,12-4-2005,15-6-2005)
insert into pilot(emp_num,pl_license,pl_ratings,pl_med_type,pl_med_date,pl_pt135_date)
values (104,'ATP','SEL/MEL/instr',1,10-5-2005,23-3-2006)
insert into pilot(emp_num,pl_license,pl_ratings,pl_med_type,pl_med_date,pl_pt135_date)

values (109,'COM','SEL/MEL/instr/CFII',1,14-4-2006,21-4-2006)


My question is there is an error in every insert

Answer

This expression 12-4-2005 is a calculated int and the value is -1997. You should do like this instead '2005-04-12' with the ' before and after.
