如何匹配配置单元查询中的特定日期格式，因为我必须获取具有除最大行数之外的日期格式的行。

EG。我的最大行的日期格式为MM / dd / yyyy，我必须列出除上述格式之外的所有行

+----------------------------+--------------------------+--------------------+-----------+
| AllocationActBankAccountID | GiftCardActBankAccountID | UpdateTimeStampUtc |   Date    |
+----------------------------+--------------------------+--------------------+-----------+
|                         14 |                       14 | 41:39.8            | 4/19/2016 |
|                         14 |                       14 | 37:16.4            | 4/20/2016 |
|                         14 |                       14 | 52:15.2            | 4/21/2016 |

Answer 1

或

select  *
from    mytable
Where   not
        (
            date rlike '^\\d{1,2}/\\d{1,2}/\\d{4}$'
        and cast(split (date,'/')[0] as int) between 1 and 12
        and cast(split (date,'/')[1] as int) between 1 and 31 
        and cast(split (date,'/')[2] as int) between 1900 and 2099 
        )

或

select  date
from    mytable
Where   coalesce(from_unixtime(to_unix_timestamp(date,'M/d/y')),'0000-01-01') 
            not between date '1900-01-01' and date '2099-12-31'
