我试图删除我正在拉的日期字段的时间部分。我正在使用Teradata。我试过了
select cast(inv_dt as date) as invoice
from tablex
无济于事仍然显示09/01/2015 12:00:00 AM 我不想把它作为一个char，因为我需要在计算日期时使用该字段。谢谢。

完全符合您的要求，您可以在日期的计算中使用 ...
如果它仍然显示时间部分，则由于您的客户（也许它假设Teradata＆＃39; cast(inv_dt as date)类似于Oracle，包括时间）。< / p>

终于想通了
select
cast(cast(inv.INV_DT- EXTRACT(DAY FROM inv.INV_DT) + 1 as date format 'mm/dd/yyyy') as char (10)) as inv_dt
from invoice inv
