So, Im having a lot of trouble with executing a query in PHP. It executes well in phpmyadmin and gives me a neat list of results.
Here is the query I inserted into phpmyadmin:
SELECT RIGHT(`Pair`, LOCATE('_', REVERSE(`Pair`))-1)
FROM `poloniex`
WHERE LEFT(`Pair`, 3) = 'BTC';
For example an entry in the Column Pair: BTC_NXT
The query should return NXT (everything right of the "_").
Now, when switching over to php while I haven't edited the query at all, I don't get any result. The dbconnection is already established; no problems on that front.
$query_get_pairs = "SELECT RIGHT(`Pair`,LOCATE('_',REVERSE(`Pair`))-1) FROM `poloniex` WHERE LEFT(`Pair`, 3) = 'BTC'";
$result_get_pairs = mysqli_query($dbc,$query_get_pairs);
var_dump($result_get_pairs) returns an empty array.
Summary:
-
poloniex
is the table name. -
Pair
is the column name which contains values like "BTC_NXT". The query should give me NXT.
