表类型变量中的复合主键 [英] Compound primary key in Table type variable

问题描述

SQL Server 2008:

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?

Is there any way to have compound Primary key in Table valued variables?

推荐答案

您可以像这样定义复合主键:

You can define a composite primary key like this:

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