Hi people, I'm having a problem with my SQL query which is not doing what I would like. I have this query: SELECT a. id, a.kataloski_broj, SUM(a.quantity) AS zbroj, entry_type_desc, posting_date, item_category, product_group, b.nabavna_cijena as neto_nabavna, b.neto_VPC, b.preporucena_VPC, c.nabavna_cijena as rabat_nabavna, c.VPC, d.VPC as NAV_VPC, d.PVPC as NAV_PVPC FROM prodaja_zaliha a LEFT JOIN kalkulacija_stavke b ON a.kataloski_broj = b.kataloski_broj LEFT JOIN kalkulacija_stavke_rabat c ON a.kataloski_broj = c.kataloski_broj LEFT JOIN katalog_pribora_item d ON a.kataloski_broj = d.kataloski_broj_NAV WHERE a.entry_type_desc = 'Prodaja' AND YEAR(a.posting_date) = '2015' AND a.kataloski_broj = 'M1200' GROUP BY a.id ASC The problem is that it returns SUM(a.quantity) AS zbroj in 1432 quantity, while there is actually 182 quantity in DB. What am I doing wrong?

Hello all! I'm makeing car booking module and have one problem. Explaining... There is tree joined tables "books", "car" and "cat".

Thanks <?php if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error . ']'); } $query = " SELECT * FROM books LEFT JOIN car ON books.car_id = car.id LEFT JOIN cat ON books.cat_id = cat.id WHERE books.owner = '$owner'"; $result = mysqli_query($db,$query) or die("Error: ".mysqli_error($db)); $myrow = mysqli_fetch_array($result, MYSQLI_BOTH); if(mysqli_num_rows($result) > 0){ if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error . ']'); } do { printf ('<tr> <td>'.$myrow["id"].'</td> <td>'.$myrow["model"].'</td> <td>'.$myrow["cat_name"].'</td> <td>'.$myrow["name"].'</td> <td>'.$myrow["surname"].'</td> <td>'.$myrow["country"].'</td> <td>'.$myrow["phone"].'</td> <td>'.$myrow["notes"].'</td> <td>'.$myrow["start_date"].'</td> <td>'.$myrow["end_date"].'</td> <td>'.$myrow["owner"].'</td> <td>'.$myrow["site"].'</td> <td><a href="delete.php?id='.$myrow["id"].'">Delete</a></td> </tr>'); } while ($myrow = mysqli_fetch_array($result)); } else{ echo '<p align="center" style="margin-top:100px;">There are no records...</p>'; } ?>

hi there, i have the following query, which is supposed to return the valid sales lead counts and average the costs and count the leads during the past 30 days. SELECT SC.text_ServiceDescription, R.text_RegionDescription, GROUP_CONCAT(DISTINCT S.text_SupplierName SEPARATOR ', ') AS text_SupplierNames, IFNULL(SW.smallint_SuppliersWanted,0) AS bigint_SuppliersWantedAmount, COUNT(DISTINCT S.bigint_SupplierID) AS bigint_PremiumCustomersCount, ROUND(AVG(T.bigint_TransactionAmount),2) AS bigint_AvgCostPerLead, ROUND(COUNT(DISTINCT LS.bigint_LeadID, LS.smallint_LeadOrdinal),2) AS bigint_AvgNumLeadsGen FROM 4_servicesuppliers SS LEFT JOIN 2_servicescatalogue SC ON (SS.bigint_ServiceID = SC.bigint_ServiceID) LEFT JOIN 1_regions R ON (SS.bigint_RegionID = R.bigint_RegionID OR SS.bigint_RegionID = R.bigint_ParentRegionID) LEFT JOIN 5_suppliers S ON (SS.bigint_SupplierID = S.bigint_SupplierID) LEFT JOIN 11_supplierswanted SW ON (SS.bigint_ServiceID = SW.bigint_ServiceID AND R.bigint_RegionID = SW.bigint_RegionID) LEFT JOIN 3_serviceattributes SA0 ON (SC.bigint_PrimaryAttributeKey = SA0.bigint_AttributeID AND SC.bigint_ServiceID = SA0.bigint_AttributeServiceID) LEFT JOIN 3_serviceattributes SA1 ON (SA0.text_AttributeDescription = SA1.text_AttributeDescription AND SC.bigint_ServiceID = SA1.bigint_AttributeServiceID) LEFT JOIN 25_serviceleads SL ON (SC.bigint_ServiceID = SL.bigint_ServiceID AND SL.text_LeadAttributes LIKE CONCAT("%",SA1.text_AttributeDescription," = ",SA1.text_AttributeValue,"%")) LEFT JOIN 27_leadssent LS ON (SL.bigint_LeadID = LS.bigint_LeadID) LEFT JOIN 8_transactions T ON (SL.bigint_LeadID = T.bigint_LeadID AND LS.smallint_LeadOrdinal = T.smallint_LeadOrdinal) WHERE S.smallint_SupplierStatus = 0 AND IFNULL(SW.smallint_SuppliersWanted,0) > 0 AND SL.timestamp_LeadCreated >= DATE_SUB(CURDATE(),INTERVAL 30 DAY) AND SL.text_LeadAttributes LIKE CONCAT("%",SA1.text_AttributeDescription," = ",SA1.text_AttributeValue,"%") AND LS.text_Duplicates = "" GROUP BY SS.bigint_ServiceID, SW.bigint_RegionID ORDER BY SS.bigint_ServiceID ASC, R.bigint_RegionID ASC; however - this query takes forever to execute, even longer than the system timeout in phpmyadmin! also via php... in php i have a microtimer attached which times the query above, at 1568.6739211082 seconds. how can i optimize the query above, especially with regard to the 25_serviceleads, 27_leadssent and 8_transactions JOIN's? i have uploaded the sql digest for the tables above to this message, to recreate this issue (removing the email addresses of course - as we do not condone spam ) to: http://performatix.co/Untapped_Potential_Income.zip please respond if you authentically know your mysql (especially the joins!) - you are welcome to assist. i have not been able to do the course myself yet - what i do know - is all as result of a lifelong hobby. sincerely, Pierre "Greywacke" du Toit.
