'函数名称：LinkSQLServerTable
'作    用：根据表名和SQL Server服务IP地址，在ACCESS中创建SQL SERVER链接表
'作    者：杨恒
'优    化：陈友福 QQ86053924 欢迎大家和我交流。
'优化日期：2017-11-29
'优化内容：将sub过程修改为函数、增加了对已有链接表的删除、添加了1个判断表在ACCESS中是否存在的通用函数
'参数说明：LinkSQLServerTable("表1,表2,表3,表n", "IP,端口号", "数据库名称", "用户名", "密码")
'调用实例：If LinkSQLServerTable("tblTest,tblTT","127.0.0.1,,1433","DataTest","sa","Pwd123") Then MsgBox "链接成功
'以下代码：在Access2016+SQL Server2014中测试通过
Public Function LinkSQLServerTable(ByVal strTableNames As String, ByVal IP As String, ByVal strDataBaseName As String, ByVal strUID As String, Optional ByVal strPwd As String = "") As Boolean
    Dim dbs As DAO.Database
    Dim tdf As TableDef
    Dim strConnect As String
    Dim arr As Variant

    Dim strSourceTableName As String
    ar = strTableNames                                                                              '要链接的SQL Server数据库表名
    arr = Split(ar, ",")
