Sql server 2008 表类型变量中的复合主键

SQL Server 2008：

DECLARE @MyTable TABLE(
    PersonID INT NOT NULL,
    Person2ID INT NOT NULL,
    Description NVARCHAR(100),
CONSTRAINT PK PRIMARY KEY CLUSTERED (PersonID, Person2ID)
);

给出：

Msg 156, Level 15, State 1, Line 5
Incorrect syntax near the keyword 'CONSTRAINT'.

---

有没有办法在表值变量中使用复合主键？

您可以这样定义复合主键：

DECLARE @MyTable TABLE
(   
    PersonID INT NOT NULL,    
    Person2ID INT NOT NULL,    
    Description NVARCHAR(100),
    PRIMARY KEY (PersonID, Person2ID)
);
