Question

我有一张包含以下记录的表

slno | FirstName | LastName | Attended | Month  | Year |
-----|-----------|----------|----------|--------|------|
1    |  John     |  Smith   |   0      |   04   | 2017 |
2    |  Jack     |  Paul    |   1      |   04   | 2017 |
3    |  Jerry    |   Tom    |   1      |   04   | 2017 |
4    |  Beth     |  Home    |   0      |   04   | 2017 |
5    |  Julia    |  John    |   1      |   04   | 2017 |
6    |  Cris     |  joy     |   0      |   05   | 2017 |
7    |  Meiy     |  Rony    |   1      |   05   | 2017 |
8    |  Ronald   |   Jony   |   1      |   05   | 2017 |
9    |  Quest    |  Pio     |   0      |   05   | 2017 |
10   |  Mary     |  June    |   1      |   05   | 2017 |
11   |  Joy      |  Meth    |   0      |   03   | 2017 |
12   |  Ruby     |  Rony    |   1      |   03   | 2017 |
13   |  Royal    |   Jony   |   1      |   03   | 2017 |
14   |  Tweet    |  Pio     |   0      |   03   | 2017 |
15   |  Min      |  June    |   1      |   03   | 2017 |

我想根据月份和年份显示数据。例如：2017年4月应仅显示4月份的数据和3月份参加的数据= 0。但是当我搜索2017年05时，它应该显示五月份的数据，包括上个月的数据，这些数据是Attended = 0 [march and april]。

我有以下声明：

select FirstName,LastName,Attended from UserTable 
where Attended in (0,1)
and ( Attended not in (1) or (Month='04' and Year='2017'));

我会得到我想要的记录。但如果我搜索Month ='03'Year ='2017'，它会显示从5月到4月的所有Attended = 0。

if   Month='05' year='2017' -- current month

    6    |  Cris     |  joy     |   0      |   05   | 2017 |
    7    |  Meiy     |  Rony    |   1      |   05   | 2017 |
    8    |  Ronald   |   Jony   |   1      |   05   | 2017 |
    9    |  Quest    |  Pio     |   0      |   05   | 2017 |
    10   |  Mary     |  June    |   1      |   05   | 2017 |
    1    |  John     |  Smith   |   0      |   04   | 2017 |
    4    |  Beth     |  Home    |   0      |   04   | 2017 |
    11   |  Joy      |  Meth    |   0      |   03   | 2017 |
    14   |  Tweet    |  Pio     |   0      |   03   | 2017 |

如果month ='04'年='2017'

1    |  John     |  Smith   |   0      |   04   | 2017 |
2    |  Jack     |  Paul    |   1      |   04   | 2017 |
3    |  Jerry    |   Tom    |   1      |   04   | 2017 |
4    |  Beth     |  Home    |   0      |   04   | 2017 |
5    |  Julia    |  John    |   1      |   04   | 2017 |
11   |  Joy      |  Meth    |   0      |   03   | 2017 |
14   |  Tweet    |  Pio     |   0      |   03   | 2017 |

如果month ='03'年='2017'

11   |  Joy      |  Meth    |   0      |   03   | 2017 |
12   |  Ruby     |  Rony    |   1      |   03   | 2017 |
13   |  Royal    |   Jony   |   1      |   03   | 2017 |
14   |  Tweet    |  Pio     |   0      |   03   | 2017 |
15   |  Min      |  June    |   1      |   03   | 2017 |

我该怎么做？

Answer 1

您可以将月份和年份解析为日期，然后像这样查询：

SELECT * FROM your_table
WHERE
('05' = `Month` AND '2017' = `Year`) 
OR
(
    '05-2017' >= DATE_FORMAT(STR_TO_DATE(CONCAT(`Mont`, '-', `Year`), '%m-%Y'), '%m-%Y')
    AND
    Attended = 0
);

Answer 2

SELECT * FROM your_table
WHERE
('05' = `Month` AND '2017' = `Year`) 
OR
(
    '05-2017' >= DATE_FORMAT(STR_TO_DATE(CONCAT(`Mont`, '-', `Year`), '%m-%Y'), '%m-%Y')
    AND
    Attended = 0
);

Mysql获取当月未处理的所有记录
