Also, the response to each of the anticipated exceptions is to do nothing, but the CONTINUE HANDLER declaration expects a complete SQL statement; hence the dummy assignment.
另外,对于每种可能出现的异常的响应是不做任何事,但是CONTINUEHANDLER声明需要一个完整的sql语句;因此使用伪赋值。
Note that the dummy variable declaration has disappeared: you don't need it because you now have an actual statement in the exception handler.
注意,伪变量声明已经没有了:不再需要它是因为现在在异常处理函数中有了实际的语句。
In the AUTHORITY-CHECK statement, all fields of the object must be addressed or the keyword DUMMY is used to bypass checking on a field.
在AUTHORITY -CHECK语句中,这个授权对象的所有字段都必须检查到,或者使用关键字DUMMY可以忽略某个字段的检查。
