在Oracle,这一回归者03/01/2010。 这对我来说没有意义。 任何人都知道为什么?
SELECT TO_DATE( 2010 , yyyy ) AS STRANGE_YEAR_RESULT
FROM DUAL
我在Oracle 10g和11g受审。
Oracle需要一个完整的日期,即其类型价值领域,因此它占用了当值<>/strong>月的第一天,我想到,因为你不需要一年以外的其他信息。 认为你总是需要通过以Oracle为标志的“DATE()”和“CHAR(CHAR)”日期。 假设是,将获得所需资料的Oracle“知识”。
我认为没有任何合理的理由,它只是“它这样做了”。 它还在一年前的网上论坛上讨论了http://forums.oracle.com/forums/thread.jspa?threadID=854498” rel=“nofollow noreferer”。
不知道,但我的猜测是,几个月是零的,因此,Jan = 0, Mar = 2等。
“10”可能是制造中的Y2K问题,但它被解释为2010年。
如果没有一天时间,也许会算起这个月的第一天。
为什么要检验? 你们永远不想这样说。
