Question

I am having a Problem with a MySQL Query. My Database Structure looks like this:

id (PRIMARY_KEY, AUTO_INCREMENT)

deviceID (TEXT)

name (TEXT)

latidude (TEXT)

longitude (TEXT)

Now this is how the first Entry looks like (in the order like above):

1 fc29daf8-bc53-4235-a1df-7d54b4e67b4c username 46.993393 5.448076

I’m search the Database with this Query:

$result = mysql_query("SELECT name FROM position WHERE deviceID = '$deviceID'");

But it doesn’t find the entry. The deviceID is obtained from $_GET and it is exactly the same as this in the database. I also checked if it is right by printing it with echo.

It is sent to the PHP file like this:

read_uniqueid.php?deviceID=fc29daf8-bc53-4235-a1df-7d54b4e67b4c

and read from the .php file like this:

$deviceID = $_GET['deviceID'];
echo $deviceID.'<br>';

After those lines the query from above is sent.

There is a working connection to the database.I only have a Problem in the query if I search the name like that it works then I get all the other Entries.

This query works and gives me all entries:

$result = mysql_query("SELECT * FROM position WHERE name = '$name'");

Answer 1

Try like,

$result = mysql_query("SELECT name FROM position WHERE deviceID like '%$deviceID%'");

the column deviceID may have space in before or after the value.
