I want to retrieve all the properties in the range 2200000(min_price) to 2700000(max_price)
The query should look like
SELECT *
FROM properties
WHERE ( ((raw_min >= '{$min_price}')
OR (raw_min <= '{$max_price}'))
AND ((raw_max >= '{$min_price}')
OR (raw_max <= '{$max_price}')))
AND (..)
query should satisfy the below 6 conditions
raw_min - raw_max
(1) 1000000-2000000 (false)
(2) 1500000- 2400000 (true)
(3) 2300000-2600000 (true)
(4) 2500000-3000000 (true)
(5) 3200000-5000000 (false)
(6) 2000000-3000000 (true)
Please try this query:-
SELECT *
FROM properties
WHERE (raw_min between 2200000 AND 2700000)
OR (raw_max between between 2200000 AND 2700000)
OR (raw_min <= 2200000 && raw_max >= 2700000)
Please check I have updated the query.

can anyone tell me why I can not run this code in SQL Management studio?
Thanks in advance.
SELECT * FROM TabKontaktJednani
where
TabKontaktJednani.Typ IN (
CASE 'ERP'--(SELECT ALIAS FROM TabCisZam where LoginId = SUSER_NAME())
WHEN 'ERP'
THEN ('HeO','OST')
WHEN 'TO'
THEN ('SW','OST')
END)
The reason you can't run that code is that CASE expressions can only return one scalar value, not a list of values.
Your CASE expression returns a tuple. That is not allowed in SQL. But as MySQL supports a boolean data type, a CASE expression may result in a boolean:
SELECT *
FROM tabkontaktjednani
WHERE
CASE (SELECT alias FROM tabciszam WHERE loginid = suser_name())
WHEN 'ERP' THEN typ IN ('HeO', 'OST')
WHEN 'TO' THEN typ IN ('SW', 'OST')
END;

I want to select multi-column and condition in a condition (nested condition) like a one below if it is written in a programming language:
(bulan_pembayaran == 7 && semester_payment == 1) && (bulan_pembayaran == 6 && semester_payment == 4)
How to make the above command for SQL query?
In general, you just use boolean operators just as you would in a programming language. mysql uses or/|| and and/&& interchangeably, but because || is a concatenation operator in other flavors of sql, it can be good to stick to or/and:
(bulan_pembayaran = 7 and semester_payment = 1) or (bulan_pembayaran = 6 and semester_payment = 4)
(The parentheses are only needed for clarity here; and is higher precedence than or, so without them it would produce the same result.)
But in this specific case, you can use mysql's support for list values and the in operator; this is especially helpful when there are more than a couple cases being checked:
(bulan_pembayaran, semester_payment) in ((7,1),(6,4))

I ask myself why this request
SELECT * FROM world.city WHERE '20181109' > datedebut and '20181109' < datefin;
doesn't return the same result as this
SELECT * FROM world.city WHERE datedebut < 20181109 < datefin;
The last select sentence is not valid SQL, but mathematically it is the optimal solution
For each operator (ie < or > ) there must be a distinct right and left side.
When you write datedebut < 20181109 < datefin it is parsed as datedebut < 20181109 and the result of that comparison is sent to the next operator.
You need to think differently when writing SQL than when writing mathematics. You can argument that both "languages" have parsers, but they are slightly different.
EDIT comment:
As I have been made aware in the comments, My original answer was not entirely correct, since that would ave given a parse error. The essence is correct: Your query is not being parsed as you expected.
As others have answered, if you want a more compact answer, you need to use the BETWEEN keyword instead of the <and > operators.
There is a MySQL expression syntax which more closely matches your second form, which is BETWEEN:
SELECT * FROM world.city WHERE '20181109' BETWEEN datedebut AND datefin

I am trying to add random number in one of my database column called likes which have about 5000 row in it. currently I have tried like below to get random number from 10 to 50.
$randomnumberlike = (rand(10,50));
but this is setting same number in all row...instead I want different number in row...anyone can please suggest how can I do it ?
Thanks
Try: UPDATE Table SET fieldName = ((rand() * 1000) % 40) + 10;
Because when you preset it in a variable, it'll be the same for all...
You're setting a variable:
$randomnumberlike = (rand(10,50));
If you're then using $randomnumberlike to add to the db then it will always be the same, its already be assigned (unless within a loop), you need to use (rand(10,50)) (or working similar) directly in the query like this:
UPDATE <table_name> SET <field_name> = ROUND((RAND() * (50-10))+10) WHERE ...;

I used Bootstrap datepicker to get date from the user. I stored that value in database.
But when i render this date in html, it showed unexpected value with the date !
I give the screen shot of the result.
Can anyone help me to solve this ?
How have you stored the date in the database?
Make sure you used DATETIME and not VARCHAR
Also how did you get the date from the database?
I would use:
$query = "SELECT DATE_FORMAT(ColumnName, '%Y-%m-%d %H:%i:%s') AS Date FROM Table";
$result = mysqli_query($cxn,$query) or die(mysqli_error());
$date = $result->fetch_object()->Date;
