  ORDER BY  AlertDate ASC 

列に出力が表示2013-04-04 00:00:00.000されますAlertDate

次のように日付のみ (時刻なし) を取得したい: 2013-04-04"AlterDate列に。

クエリのアドバイスやコードの更新を手伝ってもらえますか?

前もって感謝します

Answer 1

date代わりにタイプを使用できますdatetime

 declare @temp Table
(
iLeadID int,
Title varchar(Max),
AlertDate date
)

Answer 2

AlterDateDATETIME として入力しました。日付のみを格納する場合は、DATE データ型を使用します。これを行うことの追加の利点は、DATETIME の 8 バイトではなく、DATE データ型が 3 バイトしかとらないことです。

その後、AlterDate を DATETIME に戻す必要がある場合は、現在表示されている午前 0 時の値が使用されます。
