用UNIQUEIDENTIFIER作为PK创建表

Question

I have been trying (unsuccessfully) to create a table with a UNIQUEIDENTIFIER as the primary key. The script below will create the table just fine, however there is no PK specified. This is my first time using a UNIQUEIDENTIFIER, however. Any ideas?

T-SQL

CREATE TABLE [dbo].[AgentRelationshipCodes]
(
Id UNIQUEIDENTIFIER NOT NULL DEFAULT NEWID(),
RelationshipId char(3) NULL,
EffectiveDate datetime NULL,
LastChangeDate datetime NOT NULL,
LastChangeId char(6) NOT NULL,
AgtTableId int FOREIGN KEY REFERENCES AgentTransmission(ID)
);

Management Studio

Answer 1

"
    create table [dbo].[AgentRelationshipCodes]
    (
        ID uniqueidentifier not null primary key default newid(),
        .
        .
        .
    )
    Repeat for the other tables.
