如何使SELECT NEXT VALUE在SQL Server中工作？

我试图让以下内容在sql Server中工作时遇到一些困难：

CREATE TABLE table_X AS
    SELECT 
        NEXT VALUE FOR GROUP_A AS GROUP_ID,RISK_ID
    FROM 
        ( SELECT UNIQUE RISK_ID,FROM table_Y ) SS;

有人告诉我：

"Incorrect Syntax near the keyword 'SELECT'."
"Incorrect Syntax near the keyword 'UNIQUE'."

究竟是什么问题以及如何在sql Server中解决此问题？

解决方法

CREATE TABLE Person
(
FirstName Varchar(50),LastName Varchar(50)
);

/*
Insert Some Values Into Person
*/

CREATE SEQUENCE CountBy
    START WITH 1
    INCREMENT BY 1 ;

SELECT NEXT VALUE FOR CountBy OVER (ORDER BY LastName) AS ListNumber,FirstName,LastName
    INTO table_x
FROM Person
