将Null 值插入到 text 或 image 列不创建有效的文本指针,也不预分配 8 KB 的文本页 。 使用uniqueidentifier 数据类型创建的列存储特殊格式的 16 字节二进制值。 与标识列不同,数据库引擎 不为 uniqueidentifier 数据类型的列自动生成值。 在插入操作过程中,可以将 uniqueidentifier 数据类型的变量和 xxxxxxxx-xxxx...

Actually, there are two things to consider: When you linked the Access accdb to the SQL Server tables, were you asked to identify the Primary Keys for those tables? Did you select the appropriate field in the SQL Server tables? Also, you still have both the Access table ...
