MySQL数据库UPDATE LIKE查询错误

Question

我正在尝试使用查询

更新行

 update tblstudent a, tmpstudent2013 b set a.dob=b.doa where a.dob like '%2013%' and a.admissionno=b.admissionid;

但它给了我错误：日期时间值不正确“％2013” 请帮忙

Answer 1

使用YEAR()

update tblstudent a, tmpstudent2013 b 
set a.dob = b.doa 
where year(a.dob) = 2013
and a.admissionno = b.admissionid;

Answer 2

尝试：where YEAR(a.dob) = 2013
