Hi,

I want to write a function for my code below.

to something like :

 Public Shared Function Assign_Correct_Date_Value(ByVal strData As String) As ....?

        If IsDate(strData) Then
                                        return "'" & Format(CDate(strData), "yyyy/MM/dd") & "'"
                                    Else
                                        return DBNull.Value
                                    End If

    End Function

Is it possible?

Thank you.


If IsDate(strData) Then
                                        strSQLCommand &= "'" & Format(CDate(strData), "yyyy/MM/dd") & "'"
                                    Else
                                        strSQLCommand &= DBNull.Value
                                    End If

No.

Please see below code.

Thank you.
If ERV_Global.Is_Date_Column_Field(dtRow("ColumType")) Then
                                    If IsDate(strData) Then
                                        strSQLCommand &= "'" & Format(CDate(strData), "yyyy/MM/dd") & "'"
                                    Else
                                        strSQLCommand &= DBNull.Value
                                    End If
                                End If

That way I don't know if its possible ... if you use the same to build the insert values you can not include the date field but that way I don't think

Ok.

  If IsDate(strData) Then
                                        strSQLCommand &= "'" & Format(CDate(strData), "yyyy/MM/dd") & "'"
                                    Else
                                        strSQLCommand &= DBNull.Value
                                    End If



Does  strSQLCommand &= DBNull.Value is a valid command for insert or update?

i.e. strSQLCommand  =  "INSERT INTO TABLEA (Date) VALUES(" & DBNull.Value

Thank you.

Wait a moment ... I don't to that way a long time ago but you can try this way

If IsDate(strData) Then
     strSQLCommand &= "'" & Format(CDate(strData), "yyyy/MM/dd") & "'"
Else
     strSQLCommand &= " NULL "
End If
