MySql：如何通过检查where子句中的多个字段来更新表的列？

Question

I tried this way 我这样尝试

update message set status='Accepted' where tid=' ' and ltime=' ' and ldate=' ';

But it shows error in syntax. 但是它显示语法error 。

My row is uniquely identified through these three fields. 通过这三个字段可以唯一地标识我的行。

Answer 1

Since status is a reserved keyword 由于状态是reserved keyword

Try like this 这样尝试

update message 
set `status`='Accepted' 
where tid=' ' and ltime=' ' and ldate=' ';
