    指定者:
    
    getGeneratedKeys 在接口中 Statement
    
    返回:
    
    the result set with one row and one column containing the key

    SQLException - if this object is closed
  - getMoreResults
```
public boolean getMoreResults()
                       throws SQLException
```
    Moves to the next result set - however there is always only one result set. This call also closes the current result set (if there is one). Returns true if there is a next result set (that means - it always returns false).
    
    指定者:
    
    getMoreResults 在接口中 Statement
    
    返回:
    
    false
    
    抛出:
