具有讽刺意味的是，在许多情况下，程序甚至可能不在乎检查SELECT INTO的结果是什么，因此，条件处理程序的工作是徒劳的。

Ironically, in many cases the program may not care to even check the outcome of the SELECT INTO and the condition handler's work was in vain.

So it's these little differences that you'll very quickly acclimate to but it's these stupid little syntactic details that trips off, especially those less comfortable early on because if you leave out a single character, namely that semicolon on the right hand side, nothing will work.

你会很快适应这些,微小的区别,但我们正是要把这些罗里吧嗦的语法细节,尤其是那些让人非常头大的句子啃下来才行,因为如果我们一旦遗漏掉某个符号，譬如一个分号,从另一方面看来，很有可能什么都工作不了。
