[英]How to convert Fuzzy date as Date field in SQL and VB.net
I have a duedate field on a table which the datatype is Fuzzydate. 我在数据类型为Fuzzydate的表上有一个Duedate字段。 How to convert this to Date field in SQL and VB? 如何在SQL和VB中将其转换为Date字段?
For example the Duedate on backend is : Duedate = 20160531 and I wan to convert it as Duedate = 2016-05-31 例如后端的Duedate是:Duedate = 20160531,我想将其转换为Duedate = 2016-05-31
If this is always in the exact format you specified then you can use DateTime.ParseExact: 如果始终采用您指定的确切格式,则可以使用DateTime.ParseExact:
dateValue = DateTime.ParseExact("20160531", "yyyyMMdd", CultureInfo.InvariantCulture)
If it is in a number of different formats, you can use TryParseExact a number of times with different formats or just: 如果它采用多种不同的格式,则可以使用TryParseExact多次使用不同的格式,或者仅使用:
CDate()
Then to convert it to whatever date format you need: 然后将其转换为所需的任何日期格式:
dateValue.ToString("yyyy-MM-dd")
