Description
bool 
oci_fetch ( resource statement)
     oci_fetch() fetches the next row (for SELECT
     statements) into the internal result-buffer.
    
     如果成功则返回 TRUE,失败则返回 FALSE。
    
注: 
      In PHP versions before 5.0.0 you must use ocifetch() instead. 
      This name still can be used, it was left as alias of
      oci_fetch() for downwards compatability. 
      This, however, is deprecated and not recommended.
