有一表：
结构如下

SQL code

CREATE TABLE [dbo].[AB](    [AA] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,    [BB] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL) ON [PRIMARY]

SQL code

insert into AB(AA,AB)values('A1，A2，A3，A4，A5，A6，A7','A5，A3，A7')insert into AB(AA,AB)values('张三，李四，王五，赵柳，王八','王八，李四，张三')

SQL code

               AAA1，A2，A3(有),A4，A5(有),A6,A7(有)张三(有)，李四(有)，王五，赵柳，王八(有)
