我想从DateTime列获取日期。
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [name], [book_id], [book_name], [taken_date], [last_date], [renewed_date], [status], [comment], [fine_amount] FROM [library] WHERE ([admn_no] = @admn_no)">
<SelectParameters>
<asp:ControlParameter ControlID="TextBox1" Name="admn_no" PropertyName="Text"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
从以上这些
[taken_date]
,[last_date]
,[renewed_date]
列显示日期和时间
(例如:
4/14/2015 12:00:00 AM
)。
如何仅显示日期
(例如:
4/14/2015
)?
答案 0 :(得分:5)
您可以将CAST(column_name AS DATE)
用于Sql-server 2008及以上版本
SELECT [name], [book_id], [book_name],
cast([taken_date] as date) as [taken_date],
cast([last_date] as date) as [last_date],
cast([renewed_date] as date) as [renewed_date],
[status], [comment], [fine_amount]
FROM [library] WHERE ([admn_no] = @admn_no)

对于sqlserver 2008之前的早期版本,你可以像
那样做SELECT CONVERT(VARCHAR(10),GETDATE(),111)
所以整个查询就像这样
SELECT [name], [book_id], [book_name],
CONVERT(VARCHAR(10),[taken_date],111) as [taken_date],
CONVERT(VARCHAR(10),[last_date],111) as [last_date],
CONVERT(VARCHAR(10),[renewed_date],111) as [renewed_date],
[status], [comment], [fine_amount]
FROM [library] WHERE ([admn_no] = @admn_no)

将日期格式从yyyy/dd/mm
格式化为dd/mm/yyyy
,您可以更改为101
而不是111
SELECT CONVERT(VARCHAR(10),GETDATE(),101)
所以查询将是
SELECT [name], [book_id], [book_name],
CONVERT(VARCHAR(10),[taken_date],101) as [taken_date],
CONVERT(VARCHAR(10),[last_date],101) as [last_date],
CONVERT(VARCHAR(10),[renewed_date],101) as [renewed_date],
[status], [comment], [fine_amount]
FROM [library] WHERE ([admn_no] = @admn_no)
