DateTimePicker, Access

[torg]

I`ve got a DateTimePicker DtpDate

 

 dtpDate.CustomFormat = "dd.MM.yyyy"

 

I`ve got an access database with a table

 table tblExpenses(amount, Date)

tblExpenses.Date format format is DateTime (i.e : dd.mm.yyyy (11.01.2003))

 

I want to select sum(Amount) from tblExpenses where tblexpenses.date = dtpDate.value

 

Dim Date As String = dtpDate.Value.Month
           Dim Expences As String = cboUtgift.Text
           adExpences= New OleDb.OleDbDataAdapter("SELECT Sum(tblExpences.Amount) AS 'Totals ' from tblExpences where '" & Date & "' = Month(tblExpences.Date) ", Me.OleDbConnection)
           adExpences.Fill(dsExpences, "dtExpences")
            Me.OleDbConnection.Close()

 

What am I missing?

 

give me a code example if possible

Forgot to say: the code acts like the "WHERE" clause doesn`t work. As if the comparison isn`t a valid comparison. Anybody got an Idea about how to solve this problem?

You have it backwards, try this...

 

"......from tblExpences where tblExpences.Date = #" & dtpDate.value & "#", 

[torg]

I tried as you described, but received following message:

"Syntax error in Date in query expression "tblExpences.Date = #19.01.2003"".

 

tableExpemces.Date has Date/Time as Datatype, and short Date as format. dtpDate format is Short

 

adInntekt = New OleDb.OleDbDataAdapter("select sum(tblExpences.Amount) as Tor FROM tblExpenceswhere tblExpences.date = #" & dtpDate.value & "# ", Me.OleDbConnection)

It may have a poblem with the field name Date, it's a reserved word. In that case use square brackets...

 

 

 

.....Where [date] =....

[torg]

I solved the problem by doing the following:

Dim myString As String = dtpDato.Value
   Dim aString As String
       aString = (Replace(myString, ".", "/"))
       MessageBox.Show(aString)

       Try
           Me.OleDbConnection.Open()
   Dim Expences As String = cboExpences.Text
           adExpences= New OleDb.OleDbDataAdapter("select (tblExpences.Amount) as tot FROM tblExpences where tblExpences.date = #" & aString & "#;) ", Me.OleDbConnection)
           adExpences.Fill(dsExpences, "dtExpences")
            Me.OleDbConnection.Close()

Yeah, my fault, I forgot that dtpDato is returning a date type, so you could simply eliminate the pound (#) sign in you SQL string.

[Robby]

btw, it's preferable to use Replace from the .NET library...

 

aString = myString.Replace(".","/")
