在sql查询中获取Teacher Superannuation年龄

Question

提前致谢：请帮我解决一个sql查询，找到一个员工的退休日期，我必须得到所有那些将在不同日期年满60岁的员工，所以我需要得到这些日期从出生之日起。

TeacherName         DateOfBirth          TeacherAge     SupperannuationDate(onwhich teacher going to be 60 yers)
-------------------------------------------------------
S. KHALID SALIM 1958-03-23 00:00:00.000  55
ZUBAIDA BEGUM   1976-08-01 00:00:00.000  36
TANZEEM AKHTAR  1974-09-25 00:00:00.000  38

RABIA TABASSUM  1976-11-10 00:00:00.000   36

这是我的查询，我需要一个名为“AnnunationDate”的第四栏，教师年龄为60岁。

select  TeacherName ,DateOfBirth , datediff(mm, DateOfBirth, getdate()) / 12 as TeacherAge  from Teachers

------------------------例如，在第一行，它将显示在第四列中  1963-03-23 00：00：00.000 somthing

Answer 1

SQL服务器

SELECT
TeacherName,
dateadd(year, 60 , DateOfBirth) as superannuationDate
FROM Teachers

Mysql的

SELECT
TeacherName,
DATE_ADD(DateOfBirth, INTERVAL 60 YEAR) as superannuationDate
FROM Teachers

的Oracle

SELECT
TeacherName,
ADD_YEARS(DateOfBirth, 60) as superannuationDate
FROM Teachers
