sql – 操作数类型冲突：int与日期不兼容INSERT语句与FOREIGN KE

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_pt135_date)
values (104,'SEL/MEL/instr',10-5-2005,23-3-2006)
insert into pilot(emp_num,pl_pt135_date)
values (105,'COM','SEL/MEL/instr/CFI',2,25-2-2006,12-2-2005)
insert into pilot(emp_num,pl_pt135_date)
values (106,02-4-2006,24-12-2005)
insert into pilot(emp_num,pl_pt135_date)
      values (109,14-4-2006,21-4-2006)

我的问题是每个插入都有一个错误

Operand type clash: int is incompatible with date

如何解决这个问题？
