update api_visit_ua ua set total_count = total_count + 10 where id = '1645332340066418692'; update api_visit_ua ua set total_count = total_count + 20 where id = '1645332340066418694'; 报错了， You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'update api_visit_ua ua set total_count = total_count + 20 where id = '16' at line 7

这个错误提示是 MySQL 语法错误，因为在一个 SQL 语句中不能包含多个 SQL 语句，需要将两个 update 语句分开执行。你可以将这两个 SQL 语句分别执行，或者使用事务将这两个 SQL 语句包装起来，然后一起提交，例如：

BEGIN;
update api_visit_ua ua set total_count = total_count + 10 where id = '1645332340066418692';
update api_visit_ua ua set total_count = total_count + 20 where id = '1645332340066418694';
COMMIT;

这样就可以避免一个 SQL 语句包含多个 SQL 语句的错误了。
