选择日期SQL与替换月份到数字不起作用？

Question

I have a table containing data like this:

|-------|-------------------|
|   id  |       expired     |
|-------|-------------------|
|   1   |   03 Maret 2018   |
|   2   |   06 Juli 2018    |
|   3   |   02 April 2018   |
|   4   |   22 Agustus 2018 |
|   5   |   19 Juli 2018    |
|   6   |   27 Januari 2018 |
|   7   |   18 Mei 2018     |
|   8   |   13 Oktober 2018 |
|_______|___________________|

In the expired column, I use the language of INDONESIA , not English .

I would like to separate all content that has been expired on the website.

If now the date (08 Maret 2018) , then there should be 2 items that have been expired, including:

id = 1
id = 6

But I get different results, and the result is:

id = 1
id = 2
id = 3

I know these unsuitable results are caused by "month" that are not assigned as numbers. But I've changed it to SQL.

Here's the code I use:

$replace_month = "replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(expired, 'Januari', '01'), 'Februari', '02'), 'Maret', '03'), 'April', '04'), 'Mei', '05'), 'Juni', '06'), 'Juli', '07'), 'Agustus', '08'), 'September', '09'), 'Oktober', '10'), 'November', '11'), 'Desember', '12')";

$dateNow = date('d m Y');

$sql = $db->query("SELECT id FROM MyTable WHERE '$dateNow' > $replace_month");

while($row = $sql->fetch_array()) {
    echo 'ID : ' . $row['id'] . '<br>';
}

The result is:

1
2
3

Whereas I expect is:

1
6

When running SQL, the "month" in the expired column is already set as a number, for example 27 01 2018 , but why is the result still wrong?

The error lies in months that do not count, so it's possible to count only dates and years.

So for example now dated March 08, 2018 , then the script is only looking for the date below 08 only . As for the month is ignored. So that's what makes my code not working properly.

Anyone can help me?

I think the query compares dates as string not date format. so how about changing to date format like this. I hope this code can work.

mysql case:

$sql = $db->query("SELECT id FROM MyTable WHERE 
STR_TO_DATE('$dateNow', '%d %m %Y') > STR_TO_DATE(expired, '%d %M %Y')");

oracle case:

$sql = $db->query("SELECT id FROM MyTable WHERE 
TO_DATE('$dateNow', 'DD MM YYYY') > TO_DATE(expired, 'DD MONTH YYYY')");

if expired is date format, no need to change to date format. i don't know the DBMS can support the month string. if not, use STR_TO_DATE($expired, '%d %m %Y').
