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.

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();
