SQL Server getdate() 转换为类似“2009-12-20"的字符串
在 Microsoft SQL Server 2005 和 .NET 2.0 中,我想将当前日期转换为以下格式的字符串:YYYY-MM-DD".例如,2009 年 12 月 12 日将变为2009-12-20".我如何在 SQL 中执行此操作.
In Microsoft SQL Server 2005 and .NET 2.0, I want to convert the current date to a string of this format: "YYYY-MM-DD". For example, December 12th 2009 would become "2009-12-20". How do I do this in SQL.
表定义中此 SQL 语句的上下文.换句话说,这是默认值.因此,当创建新记录时,当前日期的默认值以上述格式存储为字符串.
The context of this SQL statement in the table definiton. In other words, this is the default value. So when a new record is created the default value of the current date is stored as a string in the above format.
我正在尝试:SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]
I'm trying: SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]
但 SQL 服务器不断将其转换为:('SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]')
But SQL server keeps converting that to: ('SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]')
所以结果就是:
'SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]'
'SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]'
以下是 Visual Studio 服务器资源管理器、表、表定义、属性显示的屏幕截图:
Here's a screen shot of what the Visual Studio server explorer, table, table definition, properties shows:
这些包装器位正在自动添加并将其全部转换为文字字符串:(N' ')
These wrapper bits are being adding automatically and converting it all to literal string: (N' ')
这就是我尝试使用我之前使用的基本 DATETIME 以外的其他内容的原因:
Here's the reason I'm trying to use something other than the basic DATETIME I was using previously:
这是我将所有内容连接到 ASP.NET GridView 并尝试通过网格视图进行更新时遇到的错误:
This is the error I get when hooking everything to an ASP.NET GridView and try to do an update via the grid view:

注意:我添加了一个相关问题来尝试解决 正在使用的 SQL Server 不支持数据类型日期"错误,因此我可以按照建议使用 DATETIME.
Note: I've added a related question to try to get around the SQL Server in use does not support datatype 'date' error so that I can use a DATETIME as recommended.
