apex_application.g_print_error_messageis a variable, so you can set it to a value like '<span style="color:GREEN">Message</span>' but you can't executeit as a "command".
apex_application.g_print_error_message是一个变量，因此您可以将其设置为“<span style="color:GREEN">Message</span>”之类的值，但您不能将其作为“命令”执行。

No apex_application.g_print_error_messageis available, only apex_application.g_print_success_messageis.
没有apex_application.g_print_error_message可用，只有apex_application.g_print_success_message是。
Can try apex_errorpackage. See Using APEX_ERROR to manage custom error messages.
可以试试apex_error包。请参阅使用 APEX_ERROR 管理自定义错误消息。
