View 6 RepliesI have a DataSet where I need to filter the collection where one of the date columns is not null.
How do you term this in LINQ?
This is what I have so far but there is a compiler error on the w.CompletedDate field in the Where clause.
Dim completed = From ins In InspectionDataset.Inspection.AsEnumerable _
Where (Function(w) w.CompletedDate IsNot Nothing) _
Order By ins.Field(Of DateTime)("UpdatedDate")
I have also tried it the below way but the compiler will not allow the DBNull comparison.
Dim completed = From ins In Inspection.AsEnumerable _
Where ins.Field(Of DateTime)("CompletedDate") <> DBNull.Value _
Order By ins.Field(Of DateTime)("UpdatedDate")
I am pulling a date value from my database:
Dim qfresho = From p In dbConfig.Configs _
Where p.Description = "FROD" _
Select p.dateValue
Dim qfreshc = From p In dbConfig.Configs _
Where p.Description = "FRCD" _
Select p.dateValue
Then comparing these date values to the current date:

But for some reason its always returning the Else condition - even though the values in the database should make the query true. I'm guessing for some reason its not pulling the results as a date?

it's a log in form and I need to put case-sensitive validation in other words if your Username = Admin then Admin != admin Consider this code block (VB is really unfamiliar for me so break it to me gently ^^) This is after it has matched a record in the database to the parameter passed to the function LogIn()

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

View 2 RepliesI am trying to convert a string into Date (to put it later into INSERT command). My problem is that the string I am reading is always different (there is no rule what format it is going to be - as this is user-dependent).I found such piece of code on the stackoverflow:
DateTime myDate =
DateTime.ParseExact("2009-05-08 14:40:52,531",
"yyyy-MM-dd HH:mm:ss,fff",
System.Globalization.CultureInfo.InvariantCulture)
but in my case it will not work as I don't know what kind of format I am going to import.Is there any universal import function which checks all known formats? If now how should I write it?
