------解决方案--------------------
调过程或者函数的时候，call{ }里面的参数无效，检查一下。
------解决方案--------------------
看看连接数据库的实例名有没写对，以及连接参数比如驱动名、URL、用户名、密码等。
------解决方案--------------------

检查{}里面的参数
------解决方案--------------------
你写的SQL不要连数据库？连数据的配置文件或实例名看看是否正确，就是这个意思
------解决方案--------------------
可能是传递的参数和数据库定义的字段数据类型不一致造成的，可以检查下
