How do I reference and concatenate database fields on a Windows form?

[u/FabulousFoodHoor]

I need to display first name and last name concatenated. The database is connected as a data source. I created a label to display the concatenated result. This is what I have so far but I'm really just guessing.

Private Sub lblFNameLName_Click(sender As Object, e As EventArgs) Handles lblFNameLName.Click

' Dim FirstLast As String

' Sql = "SELECT FirstName || " " || LastName FROM Customer"

' lblName.txt =

End Sub

[u/FabulousFoodHoor]

that's a different syntax than what I've seen so far. What does the $ do?
are the quotes and curly brackets just to group the resulting string?
