SQL datetime to string format - sql

Question

I have some code which declares an object variable, and this variable is assigned a value from an existing database field.
Dim datestart As Object
datestart = dbToDate(dr("DateStart"))
The variable is then passed through a function which checks whether or not it is null, and then converts it into datetime data type.
Public Shared Function dbToDate(o As Object) As DateTime
If o Is DBNull.Value Then
Return Nothing
Else
Return Convert.ToDateTime(o)
End If
End Function
The last thing I need to do with it is convert it into a date formatted string, DD/MM/YYYY, so that I can insert it into a new database.
The function that I have so far is
Public Shared Function sqlDate(dt As DateTime) As String
Return "'" & Format(dt, "yyyyMMdd") & "'"
End Function
However, when I run the code, I get the following error message
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Why is this, and how do I fix it?

Answer 1

Simply, you can use toString function. Also check your timezone. The problem might be in the time zone setting.
Hope you are passing date as string to database, Try to pass date as Datetime variable rather than string
Public Shared Function sqlDate(dt As DateTime) As String
Return dt.toString("yyyy-MM-dd")
End Function
