Question

我想在日期之间获取数据。我有一些来自和迄今的记录。现在我想用日期检查该记录。

Employee  Leave_from_date  Leave_to_date Leave_Type
001       06-10-2012       07-10-2012    Casual

我想使用像这样的

这样的select语句

 Select * from leave_request where fldempid=001 as L on fldfromdate
     >= 06-10-2012 and fldtodate<='06-10-2012'

如果使用07-10-2012意味着再次显示上述记录。

请帮我创建这个......

Answer 1

在between子句中反转值和列的通常位置：

select * 
from leave_request 
where fldempid = 001
and '06-10-2012' between fldfromdate and fldtodate

Answer 2

试试这个：

SELECT Employee, Leave_from_date, Leave_to_date, Leave_Type 
FROM  leave_request 
WHERE fldempid = 001 AND 
      DATE('06-10-2012') between fldfromdate and fldtodate

Answer 3

我建议先将日期转换为unix时间戳，以便使用<= >=运算符进行安全比较

e.g

SELECT
Employee, Leave_Type  
UNIX_TIMESTAMP(fldfromdate) AS Leave_from_date, 
UNIX_TIMESTAMP(fldtodate) as Leave_to_date 
FROM 
leave_request
where 
fldempid=001 as L on 
Leave_from_date>=1349481600 and Leave_to_date<=1349481600;

没有尝试过上述内容，但应该使用一些推文...

使用mysql获取两个日期之间的记录
