I am having trouble figuring out what's wrong whit my code. The code is used to take out specific columns from 2 big tables from a database. But we also need to sum 1 specific value when after I have used the query.
The problem is in this part
$query = substr($query, 4);
$sql2 = "SELECT SUM(Forspris) FROM orderrad
JOIN orderhuvud on orderhuvud.OrderKund = orderrad.Orderdatum
where ". $query;
echo $sql2;
$result = mysqli_query($conn, $sql2) or die(mysqli_error($conn));
while($row = mysqli_fetch_array($result)){
echo print_r($row); }
this is the error i get:
SELECT SUM(Forspris) FROM orderrad JOIN orderhuvud on orderhuvud.OrderKund = orderrad.Orderdatum where OrderKund = '15' AND Orderdatum between '2015-04-16' AND '2015-05-06'Unknown column 'orderrad.Orderdatum' in 'on clause'
but it longer up in the code it can find the column orderdatum in the query
