I have a field in the database of type POINT (phpMyAdmin). I use this column to save gps coordinates.
Now I want to extract the value of latitude and longitude from database.
Can I do that without having to add other fields?
$query="SELECT * FROM risk_disposal WHERE id=$id";
$result=mysqli_query($conn,$query);
while ($row2 = mysqli_fetch_array($result))
{echo "$row2['gps']";}
Database
Try it:
SELECT ST_X(point), ST_Y(point) FROM ...

I have a table that have a CP value (numeric), for example, 28030, 28060, 27100 etc. And the user can introduce a number via PHP. I want to, having this number for example, 28050, order in MYSQL my table putting 28060 as the first position.
This is the basic of my table:
SELECT * FROM `tiendas` ORDER BY `CP`
ABS() will work. Here's a query that does the job:
SELECT
CP
FROM tiendas
ORDER BY ABS(CP- 28050) ASC

I want to extract each row from a table, but in random order. How can I do that? I tried using rand(), but I was not successful.
My database is named "permis54_permis-online-date" and my table is named: "intrebari".
Use ORDER BY RAND() MySQL:
SELECT column FROM intrebari
ORDER BY RAND()
select * from intrebari order by rand();

I'm trying to obtain a column name EmailId from the table named Users. But it returns only the first string and nothing else?
PHP:
$sql="SELECT EmailId FROM Users;";
$result =mysqli_query($conn,$sql);
$col=mysqli_fetch_array($result);
The database has 3 email-ids but count($col) returns only 1. Why so?
Thanks in advance.
The database has 3 email-ids but count($col) returns only 1. Why so?
Because
$col=mysqli_fetch_array($result);
only fetch the first row according to the internal pointer of the dataset, and therefore
count($col)
returns 1 because $col is an array having 1 item.
