VB.net中来自标签的SQL过滤器日期

Question

I am stuck with little problem. I have a sql database with DATE column. It is populated from a Label like this: Label1.text = Date.today and need to show records from one date in datagridwiev . So I need filter date using date from Label. So far I have this:

 Public Sub ShowData()
        cmd = New SqlCommand("Select * FROM Cisnik WHERE Datum = #" & Label3.Text & "# ", con)
        If con.State = ConnectionState.Closed Then con.Open()
        myDA = New SqlDataAdapter(cmd)
        myDataSet = New DataSet()
        myDA.Fill(myDataSet, "Cisnik")
        DGV3.DataSource = myDataSet.Tables("Cisnik").DefaultView
    End Sub

This code throws : Incorrect syntax near '11.'. The number 11 is a part of European form of date 24.12.2018 Incorrect syntax near '11.'. The number 11 is a part of European form of date 24.12.2018 The database works OK. Only need this filter problem to solve.

Answer 1

Try:

 cmd = New SqlCommand("Select * FROM Cisnik WHERE Datum = '" &  cdate(label3.Text).ToString("yyyy-MM-dd") & "'", con)

Your query will be:

Select * FROM Cisnik WHERE Datum = '2018-11-11'
