MySQL 8 触发器 - 字段列表中未知表“NEW”

Question

我正在建立一个数据库并尝试实施触发器。所有表和触发器都在没有警告的情况下上传到数据库中，但是当我在表操作符更新时激活触发器时，我收到一条错误消息

UPDATE operator SET `NAME_FIRST`='JOHN' WHERE `OPERATOR_ID`=0;

SQL Error (1109): Unknown table 'NEW' in field list

我怀疑它在审核员触发器中。

使用 HEIDISQL 导出数据库

我尝试替换触发器中的

NOW.%Value%

，但这有时会阻止错误出现，但并非总是如此

编辑：错误也显示为

insert into auditor (`Operator_ID`,`IS_ACTIVE`) VALUES (2, 'FALSE');

。

显然，错误仅在审核员表发生更改或审核员记录的父级发生更改时显示，明确指向该过程

Answer 1

我发现了导致问题的

NEW

引用，作为auditor_validation过程的一部分，将其更改为参数修复了问题并允许插入审计表并更新操作员表
