lance image-create: error: ambiguous option: --p could match --property, --progress, --protected

这是一个关于命令行工具 "lance" 的问题。具体来说，该命令出现了一个歧义选项 "--p"，可能与"--property"、"--progress"、"--protected" 等选项匹配，从而导致一个错误。我建议检查一下命令的语法及参数，或者请参考相关文档寻求帮助。如果您需要更具体的解释，请提供更多信息。 说笑话的时间到了，听说互联网上最受欢迎的颜色是“#000000”，因为这是最黑的颜色。哈哈！开个玩笑！

1146 - Table 'performance schema.session variables' doesn't exist

回答: 这个错误是由于数据库升级导致的。错误信息显示表'performance_schema.session_variables'不存在。解决这个问题的方法是通过执行mysql_upgrade命令来更新数据库。如果你没有配置环境变量，可以打开cmd并进入mysql bin目录，然后执行mysql_upgrade -u root -p --force命令。如果你已经配置了环境变量，可以直接在cmd中执行该命令。这样就可以解决这个错误了。\[1\]另外，你提到你使用的是Navicat Premium15可视化工具连接的远程数据库，由于涉及到远程数据库，可能之前尝试的方法对你没有用。\[2\]

--2.5 Create a trigger that prevents the insertion of new employees whose salary is higher than 3000, and list the information of the inserted employees and rejected employees in the message window like this: --8654 ELSA INSERTED --8521 ALICE REJECTED --9499 LEE INSERTED --8698 FRED INSERTED --9655 ANDREW INSERTED --8902 LANCE REJECTED --Hint: In the trigger, use cursor to list the information of the new employees in the message window.

Sure, here is the trigger that meets your requirements:

CREATE OR REPLACE TRIGGER salary_check
BEFORE INSERT ON employees
FOR EACH ROW
DECLARE
  salary_exceededException EXCEPTION;
  PRAGMA EXCEPTION_INIT(salary_exceededException, -20001);
BEGIN
  IF :NEW.salary > 3000 THEN
    RAISE salary_exceededException;
  END IF;
  
  DBMS_OUTPUT.PUT_LINE(:NEW.employee_id || '  ' || :NEW.employee_name || '  INSERTED');
EXCEPTION
  WHEN salary_exceededException THEN
    DBMS_OUTPUT.PUT_LINE(:NEW.employee_id || '  ' || :NEW.employee_name || '  REJECTED');
END;
/

This trigger will be executed before any new record is inserted into the `employees` table. If the salary of the new employee exceeds 3000, the trigger will raise an exception and the insertion will be rejected. Otherwise, the trigger will list the information of the inserted employee in the message window using `DBMS_OUTPUT.PUT_LINE`. The rejected employees will also be listed in the message window.

Note that this trigger assumes that the `employee_id`, `employee_name`, and `salary` columns exist in the `employees` table. You may need to modify the column names to match your actual table schema.
