使用主鍵和唯一鍵創建表

Question

我正在使用sql server 2000我想要創建一個有主鍵作爲主鍵和一個有唯一鍵約束的列的表。

Answer 1

這應該做到這一點。

CREATE TABLE [dbo].[TestTable] 
(
    [id] [int] NOT NULL, 
    [otherValue] [int] NOT NULL, 
CONSTRAINT [IX_OtherValye] UNIQUE NONCLUSTERED 
(
    [otherValue] ASC 
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] 
) ON [PRIMARY] 

Answer 2

CREATE TABLE [MyTable] 
(
    ID INT NOT NULL, 
    SomeUniqueColumn varchar(20) NOT NULL, 

    CONSTRAINT PK_MyTable PRIMARY KEY(ID), 
    CONSTRAINT U_MyTable UNIQUE(SomeUniqueColumn) 
)
