怎么从 UNIX_TIMESTAMP() 中提取月,
也就是 MONTH( FROM_UNIXTIME( 1464408176 ) ) 能简写吗?主要是我觉得 MONTH( FROM_UNIXTIME( 1464408176 ) ) 这种用起来,肯定对服务器应能有影响,因为得得先把时间戳转成 字符串 ,然后 再从字符串计算,后提取月..
我做视图用的..
FROM_UNIXTIME( 1249488000, '%m' )FROM_UNIXTIME( 1249488000, '%y' )
Search for the rest!
select date(FROM_UNIXTIME(字段名)) from 表名;
To extract the year, month and day, you can use MySQL’s date_format function
date_format
FROM_UNIXTIME( 1249488000, '%m' )
