问题描述
我在我的表上有一个DATETIME列,用于存储创建记录的时间。我只想选择在特定日期创建的记录。如果我尝试:
SELECT *
从myTable
WHERE postedOn ='2012-06-06'
即使表中有许多行,也不返回任何行, postedOn
设为
2012-06-06 21:42:02
, 2012-06-06 07
$ b:解决方案
使用标量:
SELECT *
FROM myTable
WHERE date(postedOn) ='2012-06-06'
I have a DATETIME column on my table which stores when a record was created. I want to select only the records created on a particular date. If I try:
SELECT *
FROM myTable
WHERE postedOn = '2012-06-06'
It returns no rows even though there are many rows in the table with the postedOn
set as 2012-06-06 21:42:02
, 2012-06-06 07:55:17
, and so forth.
Any ideas?
解决方案
Use the DATE scalar:
SELECT *
FROM myTable
WHERE date(postedOn) = '2012-06-06'
