Answer 1

This may help:

SQL Server:

SELECT FORMAT (GETDATE(), 'MMM yyyy')  -- Jul 2019
SELECT FORMAT (GETDATE(), 'MMMM yyyy') -- July 2019
SELECT RIGHT(CONVERT(VARCHAR(11), GETDATE(), 106), 8) -- Jul 2019

MySQL:

SELECT DATE_FORMAT("20150102", "%M %Y");  -- January 2015
SELECT DATE_FORMAT("20150102", "%b %Y"); -- Jan 2015
SELECT YEAR(date) AS 'year', MONTH(date) AS 'month'

MySQL 会将日期字符串识别为日期，因此您可以使用date_format()来获取您想要的格式：

select date_format('20150102', '%b %Y')
