I have 2 buttons which execute a post operations and set a hidden variable which is used to set the MySQL query to filter the database according to date
if result = today
$query = "SELECT id,customer_name,CAST( `register_date` AS DATE ) AS dateonly,status,
DATE_FORMAT(book_date, '%m/%d/%y') FROM table WHERE book_date
BETWEEN (CURDATE() - INTERVAL 1 DAY) AND CURDATE()";
if result = week
$query = "SELECT id,customer_name,CAST( `register_date` AS DATE ) AS dateonly,status,
DATE_FORMAT(book_date, '%m/%d/%y') FROM table
WHERE book_date BETWEEN (CURDATE() - INTERVAL 7 DAY) AND CURDATE()";
I then want to use something like
$result=mysql_query($query);
while ($mytable=mysql_fetch_array($result))
{
loop and display all the information in array in a table
}
But I need the red bean equivalent of this.
The easiest way is to just paste the $query inside the sql function:
$results=R::getAll($query);
foreach($results as $row){
echo $row['id'];
}
The next way is to manually build the query.... which may just make it look sloppier in my opinion:
$results=R::$f->begin()->select('id, customer_name, CAST( register_date AS DATE ) AS dateonly,status, DATE_FORMAT(book_date, '%m/%d/%y')')->from('table')->where('book_date BETWEEN (CURDATE() - INTERVAL 1 DAY) AND CURDATE())->get();
The final way is to grab results via redbean and handle them manually:
$results=R::find('table','book_date BETWEEN (CURDATE() - INTERVAL 7 DAY) AND CURDATE()');
Then loop through the results, configuring data along the way in php.
I always use this when I have to access a lot of data from mysql:
while ($row = mysqli_fetch_array($query)) { #converts query into array
$array[] = $row;
}
$array will be a multidimensional array. $array[x][column_name] will get you your data, x being the row which you want to access it from. Hope this helped.

I am using PHP with MySQL and would like to select rows that have a booking time within 2 hours from now. How do I compare what is in my database with the NOW() MySQL function?
I have columns pickupDate in the format yyyy-mm-dd and pickupTime in the format HH:mm (24-hour). I have tried creating a query with NOW() which returns the a 12-hour time as HH:mm:ss e.g. 2019-05-24 07:54:06 . I can't figure out how to format this to 19:54, or if I should use a different function instead.
For example, if the current date and time is 24/05/19 19:54:06, I would like to select rows between 19:54 and 21:54 on this date.
My table structure is:
referenceNo VARCHAR(100)
pickupDate DATE
pickupTime VARCHAR(100)
You need to create a DATETIME compatible value out of your pickupDate and pickupTime (which you can do by CONCATing them together), then you can compare that with a time range from NOW() to 2 hours later:
SELECT *
FROM yourtable
WHERE CONCAT(pickupDate, ' ', pickupTime) BETWEEN NOW() AND NOW() + INTERVAL 2 HOUR
Demo on dbfiddle
To add two hours in php
$hoursnow = date('H:i');
$timestamp = strtotime(date('H:i')) + 60*60*2;
$plusTwohours = date('H:i', $timestamp);
And $PlusTwohours using this variable frame the query like below
Sql Query:
$sqlQuery = 'select * from foodorder where pickupDate=DATE(NOW()) AND pickupTime>='.$hoursnow.' and pickupTime<='.$plusTwohours;
$result = mysql_query($sqlQuery);
variable $result will have the values of query
For Second Scenario: Adding hours to end of the day May 24 23:30:00
This should be handle by two different date for same column pickupDate
$d = new DateTime('2011-01-01 23:30:30');
$startDate = $d->format('Y-m-d H:i:s'); // For testing purpose assigned manually
$starttime = date('H:i');
// Here Process start, storing end date by adding two hours
$enddate1 = strtotime($startDate) + 60*60*2;
$enddate = date('Y-m-d', $enddate1); // Extracting date alone
$endtime = date('H:i', $enddate1); // Extracting time alone
Have to compare start and end date for column pickupDate, here is the query
$sqlQuery = "select * from foodorder where pickupDate>=DATE(".$startDate.") AND pickupDate<=DATE(".$enddate.") AND pickupTime>='".$starttime."' AND pickupTime<='".$endtime."'";
$result = mysql_query($sqlQuery);
I need to find max date from a table(mysql database). I am storing my date as varchar.
select max(completion_date) from table_name returns wrong value.
http://sqlfiddle.com/#!9/c88f6/3
Assuming the date time format you have in your fiddle (e.g. '12/19/2012 05:30 PM') then:
select max(STR_TO_DATE(completion_date, '%m/%d/%Y %l:%i %p')) from test;
http://sqlfiddle.com/#!9/c88f6/15
It's unclear if you want to factor the time into your rankings or just the date. This example accounts for time too, but you can remove that part of the formatter if desired.
I am not sure why you would want to keep it as varchar not date.
But this will work for varchar:
SELECT completion_date
FROM test
ORDER BY STR_TO_DATE(completion_date, '%m/%d/%Y') DESC LIMIT 1;
http://sqlfiddle.com/#!9/c88f6/10
<?php
// Store dates
$dates = array();
// Loop through and transfer the result set
foreach ($result as $row => $data) {
$dates[$row] = $data['date'];
}
// Sort the array
usort( $dates, "date_sort_function" );
// Max is last date in array.
foreach ($dates as $date) {
$max = $date;
}
?>
Well, something like that. It is a php script and all you have to provide is the sorting function which returns 0 if equal, 1 if older, and -1 if earlier.
I want to select the data between two dates and I wrote the query as follows:
SELECT *
FROM hospital_details
WHERE expirydate BETWEEN '03/13/2015' AND '03/18/2015'
But it also displays the results of 03/17/2016
How can I solve it?
You could write single syntax.
SELECT * FROM hospital_details WHERE ExpiryDate BETWEEN '$Date' AND '$b';
The active record where function will take an associative array;
$array = array('expirydate >= ' => $Date, 'expirydate <= ' => $b);
$this->db->where($array);
or a custome string;
$where = "expirydate > ='$Date' AND expirydate < ='$b'";
$this->db->where($where);
Obviously, make sure your variables are in the right format.

Hi how can I do a query like this in zf2 with zend\db\sql?
Query:
SELECT * FROM table WHERE field = $field AND data > SUBDATE(NOW(), INTERVAL 1 DAY)
In ZF2
$select = $this->sql->select();
$select->from(self::MYTABLE)
->where(array('fiels' => $field))
->where(array('data > ' => 'SUBDATE(NOW(), INTERVAL '.$lifetime.' SECOND'));
$statement = $this->sql->prepareStatementForSqlObject($select);
return $statement->execute()->current();
change the line
->where(array('data > ' => 'SUBDATE(NOW(), INTERVAL '.$lifetime.' SECOND'));
to
->where(array('data > ?' => 'SUBDATE(NOW(), INTERVAL '.$lifetime.' SECOND'));
From the code snippet, it's seen you had missed the place holder for the parameter(?), include a question mark, I had mentioned the existing line of code and the modified code for quick reference
There's no parameter there so it doesn't need to be an array. Assuming you know $lifetime is a safe, integer value, try:
->where('data > SUBDATE(NOW(), INTERVAL '.$lifetime.' SECOND)');
I need to retrieve data from within a specific date range.Anybody can help me to create a query to getting the information within date range 12-12-2009 to 12-15-2009 from a mysql table.(including 12 and 15)
SELECT * FROM foo WHERE timestamp BETWEEN "2009-12-12" AND "2009-12-15"
Use this function in php first
function ChangeDateforDB($inputdate) {
if($inputdate>0) {
$month = substr($inputdate,0,2);
$date = substr($inputdate,3,2);
$year = substr($inputdate,6,4);
$show = $year."-".$month."-".$date;
return $show;
}
}
After that you can use this in query like this in the checking condition,
checkdate >= '".ChangeDateforDB($fromdate)."' and checkdate <= '".ChangeDateforDB($todate)."'
Check this one, you can get the correct answer.
SELECT ... WHERE DATEDIFF('2009-12-15',yourdatefield) <= 3 ...
