SQL错误IS操作数类型冲突：int与日期不兼容

Question

CREATE TABLE prime_emp (
emp_id INT not null,
first_name VARCHAR(14) not null,
 last_name VARCHAR(14) not null,
 birth_date DATE not null,
 father_name VARCHAR (14) not null,
 mather_name VARCHAR (14),
joing_date DATE not null,
departmen VARCHAR(14) not null,
Primary key (emp_id)
)
select * from prime_emp
insert into prime_emp
(emp_id,first_name,last_name,birth_date,father_name,mather_name, joing_date,departmen)
values(01,'Ashish','Soni',15-07-1990,'Suman','Usha',28-10-2013,'Media');

But I got an error message:

Msg 206, Level 16, State 2, Line 13 Operand type clash: int is incompatible with date

Answer 1

Write date field as following pattern {d 'yyyy-mm-dd'}

Another appoint: emp_id = 1 not 01, because emp_id is int so 0 has lost.

Try this:

insert into prime_emp
(emp_id,first_name,last_name,birth_date,father_name,mather_name, joing_date, departmen)
values
(1,'Ashish','Soni',{d '1990-07-15'},'Suman','Usha',{d '2013-10-28'},'Media');

Answer 2

You should give quotes around date values . Other wise it will be treated as an arithmetic expression.

So change your insert query to

insert into prime_emp
(emp_id,first_name,last_name,birth_date,father_name,mather_name, joing_date,departmen)
values(01,'Ashish','Soni','15-07-1990','Suman','Usha','28-10-2013','Media');
