Question

查询MYSQL以获取＆＃39; current_date＆＃39;中的记录今天的日期，＆＃39; No＆＃39;查询日期返回数据。相反，它返回

"MySQL returned an empty result set (i.e. zero rows). ( Query took 0.0004 sec )"

已尝试且以下查询均未返回任何记录。

TRIED SQL QUERIES：

SELECT hash FROM malware_db WHERE current_date like '%2017-07-10%'

SELECT hash FROM malware_db WHERE date(current_date) like '%2017-07-10%'
SELECT hash FROM malware_db WHERE date(current_date) between date('2017-07-10 00:00:00') AND date('2017-07-10 23:59:59')

SAMPLE DB RECORDS

在＆＃34; Type＆＃34;的结构current_date中列是＆＃34; datetime＆＃34; 。

不确定，这里有什么问题？有什么建议吗？

Answer 1

SELECT hash FROM malware_db WHERE DATE( current_date ) = '2017-07-10'

但这听起来好像你没有找到合适的数据库/表格，因为所有这些建议都应该有效。

Answer 2

select hash from malware_db where date(current_date) = date(now());

MySQL为日期查询返回了一个空结果
