在vs2010 vb.net中獲取sql語句的結果

Question

我正在執行一條sql語句，以獲取數據庫中所有以“ A”開頭的數據。

Sub searchMap()
    Dim connectionString As String = ConfigurationManager.ConnectionStrings("WeddingPerfectionConnectionString").ConnectionString
    Dim connection As SqlConnection = New SqlConnection(connectionString)
    connection.Open()
    Dim sql As String = "SELECT LocationName FROM MapSearch WHERE LocationName=" Like ("1%")
    Dim command As SqlCommand = New SqlCommand(sql, connection)
    Dim reader As SqlDataReader = command.ExecuteReader()
    Dim customerId As Integer
    If (reader.Read()) Then
        customerId = reader.GetValue(0)
    End If
    reader.Close()
End Sub

我想得到結果並顯示在標簽中。

我該怎么做呢？

在SQL Server中：

Dim sql As String = "SELECT LocationID, LocationName FROM MapSearch WHERE LocationName LIKE 'A%'"

像（Transact-SQL）
