Compound primary key in Table type variable
SQL Server 2008:
DECLARE @MyTable TABLE(
PersonID INT NOT NULL,
Person2ID INT NOT NULL,
Description NVARCHAR(100),
CONSTRAINT PK PRIMARY KEY CLUSTERED (PersonID, Person2ID)
);
Gives:
Msg 156, Level 15, State 1, Line 5
Incorrect syntax near the keyword 'CONSTRAINT'.
Is there any way to have compound Primary key in Table valued variables?
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)
);
