我知道 $m->debug(); 正如这里提到的

但我不确定我应该如何开始调试以下问题。我的方法是在 dsql.php 中做一个 var_dump 并比较字段，然后在 OOP 层中逐步向上。我想知道是否有一些简单的方法可以做同样的事情。

实际错误：

/Users/Qambar/Work/VERYCOOLAWESOMEPROJECT/atk4/lib/DB/dsql.php  :1518   bozims_db_db_dsql_mysql DB_dsql_mysql-  >exception("Database Query Failed")

通常 - 做一个 debug() 它会给你一个查询本身。将查询复制粘贴到 SQL 控制台中。如果您在那里遇到错误，请尝试了解原因。

您还可以使用 setActualFields 来缩小查询的字段列表，这将使您的查询更简单。

这应该可以帮助您缩小问题的范围。
