题目中的异常处理块未显式处理`ZERO_DIVIDE`,但包含`WHEN OTHERS THEN`分支。`OTHERS`会捕获所有未被其他分支显式处理的异常,因此此时`test.result`会被插入`'ERROR4'`。 1. **ERROR1**(NO_DATA_FOUND):在查询无结果时触发,与除数为0无关。 2. **ERROR2**(TOO_MANY_ROWS):在单行查询返回多行时触发...
no_data_found异常的处理方法 在PL/SQL中,no_data_found异常可以通过在代码中使用EXCEPTION块来捕获并处理。当查询结果为空时,程序控制流会跳转到EXCEPTION块中对应的WHEN no_data_found THEN部分,从而允许开发者自定义处理逻辑,如输出错误消息、记录日志或执行特定的业务逻辑等。
在MySQL中处理no_data_found异常是非常重要的,它可以帮助我们更好地管理程序的异常情况,并保证程序的稳定性和可靠性。通过合理地编写异常处理代码,我们可以更好地应对no_data_found异常,提高程序的鲁棒性和可维护性。希望本文对您有所帮助!
