在SQL命令中删除毫秒

Question

有了这种SQL语句，如何从“ date_created”列中删除毫秒？

SELECT sales.id,
       sales.filename,
       account.description customer,
       sales.uploaded,
       sales.date_created
  FROM account
       JOIN salesStore sales
            ON sales.customer_id = account.id
 WHERE sales.date_created::date BETWEEN '2014-02-27' 
                                    AND '2014-03-01'
ORDER BY 
       sales.date_created DESC

Answer 1

尝试这个

 DATE_TRUNC('second', sales.date_created);

请参阅DATE_TRUNC的文档。
