sql - 删除 SQL 命令中的毫秒数

Question

有了这种 SQL 语句，如何从“date_created”列中删除毫秒数？

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

试试这个

 DATE_TRUNC('second', sales.date_created);

请参阅 DATE_TRUNC 的文档.
