MONTHS_BETWEEN 函数无法识别

Question

微软 SQL 服务器 2008

select months_between
   (TO_DATE('1992-09-12','yyyy','mm','dd'), TO_DATE('1991-08-23','yyyy','mm','dd') ) "months"
   from sales 

帮助

Answer 1

在 SQL Server 2008 中，使用DATEDIFF()：

SELECT DATEDIFF(mm, '23-08-1991', '12-09-1992') as "months"
FROM sales

我认为MONTHS_BETWEEN是oracle。
