我想更新格式为dd-mm-yy的日期列。在我的数据库中，该列为date数据类型。因此，在更新时我将数据作为
05-12-2017但是收到错误
ORA-01843：不是有效月份
在我的存储过程中，我将其作为
发送 HOTO_ACCEPTENCE_DATE = TO_DATE(PHOTO_ACCEPTENCE_DATE, 'dd-m-yy'),

答案 0 :(得分：3)
HOTO_ACCEPTENCE_DATE = TO_DATE(PHOTO_ACCEPTENCE_DATE, 'DD-MM-YY')
TO_DATE( date_string, format_model, nls_params )将字符串作为第一个参数，因此Oracle必须将非字符串参数隐式转换为字符串，并且实际上是这样做的：
HOTO_ACCEPTENCE_DATE = TO_DATE(
TO_CHAR(
PHOTO_ACCEPTENCE_DATE,
( SELECT value
FROM NLS_SESSION_PARAMETERS
WHERE parameter = 'NLS_DATE_FORMAT' )
),
'DD-MM-YY'
)
如果NLS_DATE_FORMAT会话参数与DD-MM-YY不匹配，那么您将收到错误消息。由于NLS_DATE_FORMAT是一个会话参数，并且可以由每个用户更改，因此依赖于此是代码在用户更改其设置时开始引发异常的一种方式，而代码不会发生变化。
您想要做的只是使用：
HOTO_ACCEPTENCE_DATE = PHOTO_ACCEPTENCE_DATE,
当您将日期存储为日期时，您不需要将日期转换为任何内容。
我想更新我的日期列，格式为
dd-mm-yy。
日期没有格式 - 它是stored internally to the database as 7-bytes（表示年，月，日，小时，分钟和秒），直到您使用的是任何用户界面（即SQL / Plus，SQL）开发人员，Java等）尝试将它显示给您，即用户，并将其转换为您会发现日期具有格式的有意义（通常是字符串）的内容。
答案 1 :(得分：0)
答案 2 :(得分：0)
考虑到您发布的格式'dd-m-yy'，似乎月份部分不正确。它应该是MM而不是M。
