Question

我想制作同一张桌子的2个字段（名字和姓氏）＆＃34;客户＆＃34;插入时大写。

mysql> show triggers LIKE 'clients'\G;
*************************** 1. row ***************************
             Trigger: ucase_insert
               Event: INSERT
               Table: tlc
           Statement: SET NEW.firstname = upper(NEW.firstname)
              Timing: BEFORE
             Created: 2017-02-04 11:53:45.87
            sql_mode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
             Definer: root@%
character_set_client: utf8mb4
collation_connection: utf8mb4_unicode_ci
  Database Collation: utf8_general_ci

我使用phpmyadmin作为界面。似乎我无法添加额外的第二个语句，如...

           Statement: SET NEW.lastname = upper(NEW.lastname)

...应该在与第一个事件和时间相同的事件和时间触发。

这可能吗？

我找到了解决方案。使用BEGIN / END，我可以包含多个语句。看起来很琐碎，但我花了很长时间才发现......

mysql> show triggers LIKE 'clients'\G;
*************************** 1. row ***************************
             Trigger: ucase_insert
               Event: INSERT
               Table: tlc
           Statement: BEGIN
SET NEW.firstname = upper(NEW.firstname);
SET NEW.lastname = upper(NEW.lastname);
END
           Timing: BEFORE
             Created: 2017-02-04 11:53:45.87
            sql_mode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
             Definer: root@%
character_set_client: utf8mb4
collation_connection: utf8mb4_unicode_ci
  Database Collation: utf8_general_ci

mysql - 触发器，同一事件的多个语句＆amp;时间
