SQL - 从现在到六个月前提取时间戳的数据

Question

I would like to get data that's within the last 6 months. I have a time stamp stored but its stored as an int(11) rather then time stamp in the database.

would would be the correct sql statement to pull this data? (below is the statement I have tried but pulls 0 results - possibly due to the fact its stored as int rather then timestamp)

SELECT * FROM `Main_Stats` WHERE `Dates` >= now() - INTERVAL 6 month

Answer 1

Try this for mysql:

SELECT * FROM `Main_Stats`
WHERE from_unixtime(`Dates`,'%Y-%m-%d') >= now() - INTERVAL 6 month

Answer 2

You probably want a unix_timestamp .

Try this

SELECT * FROM `Main_Stats` WHERE `Dates` >= unix_timestamp(now()-interval 6 month)

Answer 3

Try this code

SELECT * 
FROM `Main_Stats`
WHERE `Dates` >= DATEADD(MONTH, -6, GETDATE())
