SQL Server2000怎么去掉字段得自增属性

[donny2000]

使用SQL语句来写是怎么些得

使用SET IDENTITY_INSERT可以手动插入表示列的值：
一个例子：
-- Create products table.
CREATE TABLE products (id int IDENTITY PRIMARY KEY, product varchar(40))
GO
-- Inserting values into products table.
INSERT INTO products (product) VALUES ('screwdriver')
INSERT INTO products (product) VALUES ('hammer')
INSERT INTO products (product) VALUES ('saw')
INSERT INTO products (product) VALUES ('shovel')
GO

-- Create a gap in the identity values.
DELETE products
WHERE product = 'saw'
GO

SELECT *
FROM products
GO

-- Attempt to insert an explicit ID value of 3;
-- should return a warning.
INSERT INTO products (id, product) VALUES(3, 'garden shovel')
GO
-- SET IDENTITY_INSERT to ON.
SET IDENTITY_INSERT products ON
GO

-- Attempt to insert an explicit ID value of 3
INSERT INTO products (id, product) VALUES(3, 'garden shovel').
GO

SELECT *
FROM products
GO
-- Drop products table.
DROP TABLE products
GO


如果你想修改的是字段的属性，使用alter语句即可

这个是sql server 自己修改identity的语法！你好好看看！也许有用
