我正在使用下面的代码使用姓氏和选定状态填充 ajax 自动完成文本框。因此，如果用户键入“Jones”，它将填充姓氏类似于“Jones”的所有行。是否可以添加另一个参数以便用户可以键入“Jones, John”？所以它也会查找 ", John" ？谢谢！

Public Function GetCompletionList(prefixText As String, count As Integer, ByVal contextKey As String) As String()
    Try
        Dim Con As SqlConnection
        Dim cmd As SqlCommand
        Con = New SqlConnection
        Dim test As String
        test = contextKey
        Con.ConnectionString = ""
        Con.Open()

        cmd = New SqlCommand
        cmd.Connection = Con
        'cmd.CommandText = "SELECT NPI, [Entity Type Code], [Provider Last Name (Legal Name)], [Provider First Name], [Provider Business Mailing Address City Name] FROM NPIData WHERE [Provider Last Name (Legal Name)] LIKE @Provider + '%' AND [Provider Business Mailing Address City Name] = @State"
        cmd.CommandText = "SELECT NPI, [Entity Type Code], [Provider Last Name (Legal Name)], [Provider First Name],[Provider First Line Business Mailing Address], [Provider Business Mailing Address City Name], [Provider Business Mailing Address State Name], [Provider Business Mailing Address Postal Code] FROM NPIData WHERE     ([Provider Business Mailing Address State Name] = @State) AND ([Provider Last Name (Legal Name)] LIKE N'%' + @Provider + N'%') ORDER BY [Provider First Name]"
        cmd.Parameters.AddWithValue("@Provider", prefixText)
        cmd.Parameters.AddWithValue("@State", contextKey)
        Dim customers As List(Of String) = New List(Of String)
        Dim reader As SqlDataReader = cmd.ExecuteReader()


        While reader.Read
            customers.Add(reader("Provider Last Name (Legal Name)").ToString + ", " + reader("Provider First Name").ToString + "   " + reader("Provider First Line Business Mailing Address").ToString + "  " + reader("Provider Business Mailing Address City Name").ToString + ", " + reader("Provider Business Mailing Address State Name").ToString + "  " + reader("Provider Business Mailing Address Postal Code").ToString + "  " + reader("NPI").ToString)

        End While


        Con.Close()

        Return customers.ToArray
    Catch ex As Exception

    End Try

End Function

在您的GetCompletionList函数中，您需要拆分传入的prefixText字符串，如下所示：

' Split prefixText string by commas
Dim words As String() = prefixText.Split(New Char() {","c})

现在您可以SQL通过引用字符串的各个部分来调整您的，如下所示：

words(0) = Last Name
words(1) = First Name
