php - Unixtime 和 MySQL

Question

我的表上有一个名为 X 的字段，我存储 unixtime(php -> time())。 我的问题是:

How can I list all the months from my DB, something like: 6.2009 8.2009 etc..

我的第二个问题是:

How can I make a query to list all the informations based on a month and year on the same field X(i store unixtime), I know this doesn't work, but mabe you can understand it better: where date = '06.2009'

有什么解决办法吗？

Answer 1

• 列出所有月份:

  SELECT DISTINCT EXTRACT(YEAR_MONTH FROM FROM_UNIXTIME(X)) FROM MyTable;
  

• 返回给定年份和月份的所有行:

  SELECT * FROM MyTable
  WHERE EXTRACT(YEAR_MONTH FROM FROM_UNIXTIME(X)) = 200906;
