推荐答案
你无法'解决'异常:你抓住它并处理,在catch块中,错误。
如果'在0位没有行',那么你的查询可能会失败。根据您的情况,您可以告知用户失败,或终止应用程序或攻击海盗或其他......
You cannot 'resolve' the exception: you catch it and handle, in the catch block, the error.
If there is 'no row at position 0' then you probably have a failed query. Depending on your scenario you could inform the user of the failure, or terminate the application or attack the pirates or whatever...
